Don't mutate the container's `Config.WorkingDir` permanently with a
cleaned path when creating a working directory.
Move the `filepath.Clean` to the `translateWorkingDir` instead.
Signed-off-by: Paweł Gronowski <pawel.gronowski@docker.com>
The `normalizeWorkdir` function has two branches, one that returns a
result of `filepath.Join` which always returns a cleaned path, and
another one where the input string is returned unmodified.
To make these two outputs consistent, also clean the path in the second
branch.
This also makes the cleaning of the container workdir explicit in the
`normalizeWorkdir` function instead of relying on the
`SetupWorkingDirectory` to mutate it.

Make the internal DNS resolver for Windows containers forward requests
to upsteam DNS servers when it cannot respond itself, rather than
returning SERVFAIL.
Windows containers are normally configured with the internal resolver
first for service discovery (container name lookup), then external
resolvers from '--dns' or the host's networking configuration.
When a tool like ping gets a SERVFAIL from the internal resolver, it
tries the other nameservers. But, nslookup does not, and with this
change it does not need to.
The internal resolver learns external server addresses from the
container's HNSEndpoint configuration, so it will use the same DNS
servers as processes in the container.
The internal resolver for Windows containers listens on the network's
gateway address, and each container may have a different set of external
DNS servers. So, the resolver uses the source address of the DNS request
to select external resolvers.
On Windows, daemon.json feature option 'windows-no-dns-proxy' can be used
to prevent the internal resolver from forwarding requests (restoring the
old behaviour).

No IPAM IPv6 address is given to an interface in a network with

We document that an macvlan network with no parent interface is
equivalent to a '--internal' network. But, in this case, an macvlan
network was still configured with a gateway. So, DNS proxying would
be enabled in the internal resolver (and, if the host's resolver
was on a localhost address, requests to external resolvers from the
host's network namespace would succeed).
This change disables configuration of a gateway for a macvlan Endpoint
if no parent interface is specified.
(Note if a parent interface with no external network is supplied as
'-o parent=<dummy>', the gateway will still be set up. Documentation
will need to be updated to note that '--internal' should be used to
prevent DNS request forwarding in this case.)

The internal DNS resolver should only forward requests to external
resolvers if the libnetwork.Sandbox served by the resolver has external
network access (so, no forwarding for '--internal' networks).
The test for external network access was whether the Sandbox had an
Endpoint with a gateway configured.
However, an ipvlan-l3 networks with external network access does not
have a gateway, it has a default route bound to an interface.
Also, we document that an ipvlan network with no parent interface is
equivalent to a '--internal' network. But, in this case, an ipvlan-l2
network was configured with a gateway. So, DNS proxying would be enabled
in the internal resolver (and, if the host's resolver was on a localhost
address, requests to external resolvers from the host's network
namespace would succeed).
So, this change adjusts the test for enabling DNS proxying to include
a check for '--internal' (as a shortcut) and, for non-internal networks,
checks for a default route as well as a gateway. It also disables
configuration of a gateway or a default route for an ipvlan Endpoint if
no parent interface is specified.
(Note if a parent interface with no external network is supplied as
'-o parent=<dummy>', the gateway/default route will still be set up
and external DNS proxying will be enabled. The network must be
configured as '--internal' to prevent that from happening.)

go1.21.9 (released 2024-04-03) includes a security fix to the net/http
package, as well as bug fixes to the linker, and the go/types and
net/http packages. See the [Go 1.21.9 milestone](https://github.com/golang/go/issues?q=milestone%3AGo1.21.9+label%3ACherryPickApproved)
for more details.
These minor releases include 1 security fixes following the security policy:
- http2: close connections when receiving too many headers
Maintaining HPACK state requires that we parse and process all HEADERS
and CONTINUATION frames on a connection. When a request's headers exceed
MaxHeaderBytes, we don't allocate memory to store the excess headers but
we do parse them. This permits an attacker to cause an HTTP/2 endpoint
to read arbitrary amounts of header data, all associated with a request
which is going to be rejected. These headers can include Huffman-encoded
data which is significantly more expensive for the receiver to decode
than for an attacker to send.
Set a limit on the amount of excess header frames we will process before
closing a connection.
Thanks to Bartek Nowotarski (https://nowotarski.info/) for reporting this issue.
This is CVE-2023-45288 and Go issue https://go.dev/issue/65051.

Partially reverts 0046b16 "daemon: set libnetwork sandbox key w/o OCI hook"
Running SetKey to store the OCI Sandbox key after task creation, rather
than from the OCI prestart hook, meant it happened after sysctl settings
were applied by the runtime - which was the intention, we wanted to
complete Sandbox configuration after IPv6 had been disabled by a sysctl
if that was going to happen.
But, it meant '--sysctl' options for a specfic network interface caused
container task creation to fail, because the interface is only moved into
the network namespace during SetKey.
This change restores the SetKey prestart hook, and regenerates config
files that depend on the container's support for IPv6 after the task has
been created. It also adds a regression test that makes sure it's possible
to set an interface-specfic sysctl.

Benchmark the `Images` implementation (image list) against an image
store with 10, 100 and 1000 random images. Currently the images are
single-platform only.
The images are generated randomly, but a fixed seed is used so the
actual testing data will be the same across different executions.
Because the content store is not a real containerd image store but a
local implementation, a small delay (500us) is added to each content
store method call. This is to simulate a real-world usage where each
containerd client call requires a gRPC call.

commit c655b7dc78 added a check to make sure
the TMP_OUT variable was not set to an empty value, as such a situation would
perform an `rm -rf /**` during cleanup.
However, it was a bit too eager, because Makefile conditionals (`ifeq`) are
evaluated when parsing the Makefile, which happens _before_ the make target
is executed.
As a result `$@_TMP_OUT` was always empty when the `ifeq` was evaluated,
making it not possible to execute the `generate-files` target.
This patch changes the check to use a shell command to evaluate if the var
is set to an empty value.

This code is currently only used in the daemon, but is also needed in other
places. We should consider moving this code to github.com/moby/sys, so that
BuildKit can also use the same implementation instead of maintaining a fork;
moving it to internal allows us to reuse this code inside the repository, but
does not allow external consumers to depend on it (which we don't want as
it's not a permanent location).
As our code only uses this in linux files, I did not add a stub for other

In de2447c, the creation of the 'lower' file was changed from using
os.Create to using ioutils.AtomicWriteFile, which ignores the system's
umask. This means that even though the requested permission in the
source code was always 0666, it was 0644 on systems with default
umask of 0022 prior to de2447c, so the move to AtomicFile potentially
increased the file's permissions.
This is not a security issue because the parent directory does not
allow writes into the file, but it can confuse security scanners on
Linux-based systems into giving false positives.

So, when migrating the old container-wide MAC address to the new
per-endpoint field - it is not safe to create a new EndpointSettings
entry unless there is no possibility that it will duplicate settings
intended for the same network (because one of the duplicates will be
discarded later, dropping the settings it contains).
This change introduces a new API restriction, if the deprecated container
wide field is used in the new API, and EndpointsConfig is provided for
any network, the NetworkMode and key under which the EndpointsConfig is
store must be the same - no mixing of ids and names.

Moby imports Swarmkit; Swarmkit no longer imports Moby. In order to
accomplish this feat, Swarmkit has introduced a new plugin.Getter
interface so it could stop importing our pkg/plugingetter package. This
new interface is not entirely compatible with our
plugingetter.PluginGetter interface, necessitating a thin adapter.
Swarmkit had to jettison the CNM network allocator to stop having to
import libnetwork as the cnmallocator package is deeply tied to
libnetwork. Move the CNM network allocator into libnetwork, where it
belongs. The package had a short an uninteresting Git history in the
Swarmkit repository so no effort was made to retain history.

This patch disables pulling legacy (schema1 and schema 2, version 1) images by

A `DOCKER_ENABLE_DEPRECATED_PULL_SCHEMA_1_IMAGE` environment-variable is
introduced to allow re-enabling this feature, aligning with the environment

Commit e6907243af applied a fix for situations
where the client was configured with API-version negotiation, but did not yet
negotiate a version.
However, the checkVersion() function that was implemented copied the semantics
of cli.NegotiateAPIVersion, which ignored connection failures with the
assumption that connection errors would still surface further down.
However, when using the result of a failed negotiation for NewVersionError,
an API version mismatch error would be produced, masking the actual connection
error.
This patch changes the signature of checkVersion to return unexpected errors,
including failures to connect to the API.
Before this patch:
docker -H unix:///no/such/socket.sock secret ls
"secret list" requires API version 1.25, but the Docker daemon API version is 1.24
With this patch applied:

NegotiateAPIVersion was ignoring errors returned by Ping. The intent here
was to handle API responses from a daemon that may be in an unhealthy state,
however this case is already handled by Ping itself.
Ping only returns an error when either failing to connect to the API (daemon
not running or permissions errors), or when failing to parse the API response.
Neither of those should be ignored in this code, or considered a successful
"ping", so update the code to return

This test was added in 27ef09a46f, which changed
the Ping handling to ignore internal server errors. That case is tested in
TestPingFail, which verifies that we accept the Ping response if a 500
status code was received.
The TestPingWithError test was added to verify behavior if a protocol
(connection) error occurred; however the mock-client returned both a
response, and an error; the error returned would only happen if a connection
error occurred, which means that the server would not provide a reply.
Running the test also shows that returning a response is unexpected, and
ignored:
=== RUN TestPingWithError
2024/02/23 14:16:49 RoundTripper returned a response & error; ignoring response

This will return a single entry for each name/value pair, and for now
all the "image specific" metadata (labels, config, size) should be
either "default platform" or "first platform we have locally" (which
then matches the logic for commands like `docker image inspect`, etc)
with everything else (just ID, maybe?) coming from the manifest
list/index.
That leaves room for the longer-term implementation to add new fields to
describe the _other_ images that are part of the manifest list/index.

Non-swarm networks created before network-creation-time validation
was added in 25.0.0 continued working, because the checks are not
re-run.
But, swarm creates networks when needed (with 'agent=true'), to
ensure they exist on each agent - ignoring the NetworkNameError
that says the network already existed.
By ignoring validation errors on creation of a network with
agent=true, pre-existing swarm networks with IPAM config that would
fail the new checks will continue to work too.
New swarm (overlay) networks are still validated, because they are
initially created with 'agent=false'.

Prior to release 25.0.0, the bridge in an internal network was assigned
an IP address - making the internal network accessible from the host,
giving containers on the network access to anything listening on the
bridge's address (or INADDR_ANY on the host).
This change restores that behaviour. It does not restore the default
route that was configured in the container, because packets sent outside
the internal network's subnet have always been dropped. So, a 'connect()'
to an address outside the subnet will still fail fast.

x86/shstk: Introduce map_shadow_stack syscall
When operating with shadow stacks enabled, the kernel will automatically
allocate shadow stacks for new threads, however in some cases userspace
will need additional shadow stacks. The main example of this is the
ucontext family of functions, which require userspace allocating and
pivoting to userspace managed stacks.
Unlike most other user memory permissions, shadow stacks need to be
provisioned with special data in order to be useful. They need to be setup
with a restore token so that userspace can pivot to them via the RSTORSSP
instruction. But, the security design of shadow stacks is that they
should not be written to except in limited circumstances. This presents a
problem for userspace, as to how userspace can provision this special
data, without allowing for the shadow stack to be generally writable.

mm/mempolicy: add set_mempolicy_home_node syscall
This syscall can be used to set a home node for the MPOL_BIND and
MPOL_PREFERRED_MANY memory policy. Users should use this syscall after
setting up a memory policy for the specified range as shown below.
mbind(p, nr_pages * page_size, MPOL_BIND, new_nodes->maskp,
new_nodes->size + 1, 0);
sys_set_mempolicy_home_node((unsigned long)p, nr_pages * page_size,
home_node, 0);
The syscall allows specifying a home node/preferred node from which
kernel will fulfill memory allocation requests first.

Since 964ab7158c, we explicitly set the bridge MTU if it was specified.
Unfortunately, kernel <v4.17 have a check preventing us to manually set
the MTU to anything greater than 1500 if no links is attached to the
bridge, which is how we do things -- create the bridge, set its MTU and
later on, attach veths to it.
Relevant kernel commit: 804b854d37
As we still have to support CentOS/RHEL 7 (and their old v3.10 kernels)

Commit 4f47013feb introduced a new validation step to make sure no
IPv6 subnet is configured on a network which has EnableIPv6=false.
Commit 5d5eeac310 then removed that validation step and automatically
enabled IPv6 for networks with a v6 subnet. But this specific commit
was reverted in c59e93a67b and now the error introduced by 4f47013feb
is re-introduced.
But it turns out some users expect a network created with an IPv6
subnet and EnableIPv6=false to actually have no IPv6 connectivity.

The monitorDaemon() goroutine calls startContainerd() then blocks on
<-daemonWaitCh to wait for it to exit. The startContainerd() function
would (re)initialize the daemonWaitCh so a restarted containerd could be
waited on. This implementation was race-free because startContainerd()
would synchronously initialize the daemonWaitCh before returning. When
the call to start the managed containerd process was moved into the
waiter goroutine, the code to initialize the daemonWaitCh struct field
was also moved into the goroutine. This introduced a race condition.
Move the daemonWaitCh initialization to guarantee that it happens before
the startContainerd() call returns.

Do not set 'Config.MacAddress' in inspect output unless the MAC address

The API's EndpointConfig struct has a MacAddress field that's used for
both the configured address, and the current address (which may be generated).
A configured address must be restored when a container is restarted, but a
generated address must not.
The previous attempt to differentiate between the two, without adding a field
to the API's EndpointConfig that would show up in 'inspect' output, was a
field in the daemon's version of EndpointSettings, MACOperational. It did
not work, MACOperational was set to true when a configured address was
used. So, while it ensured addresses were regenerated, it failed to preserve
a configured address.
So, this change removes that code, and adds DesiredMacAddress to the wrapped
version of EndpointSettings, where it is persisted but does not appear in
'inspect' results. Its value is copied from MacAddress (the API field) when
a container is created.

The bbolt library wants exclusive access to the boltdb file and uses
file locking to assure that is the case. The controller and each network
driver that needs persistent storage instantiates its own unique
datastore instance, backed by the same boltdb file. The boltdb kvstore
implementation works around multiple access to the same boltdb file by
aggressively closing the boltdb file between each transaction. This is
very inefficient. Have the controller pass its datastore instance into
the drivers and enable the PersistConnection option to disable closing
the boltdb between transactions.
Set data-dir in unit tests which instantiate libnetwork controllers so
they don't hang trying to lock the default boltdb database file.

If a reader has caught up to the logger and is waiting for the next
message, it should stop waiting when the logger is closed. Otherwise
the reader will unnecessarily wait the full closedDrainTimeout for no
log messages to arrive.
This case was overlooked when the journald reader was recently
overhauled to be compatible with systemd 255, and the reader tests only
failed when a logical race happened to settle in such a way to exercise
the bugged code path. It was only after implicit flushing on close was
added to the journald test harness that the Follow tests would
repeatably fail due to this bug. (No new regression tests are needed.)
Signed-off-by: Cory Snider <csnider@mirantis.com>
The journald reader test harness injects an artificial asynchronous
delay into the logging pipeline: a logged message won't be written to
the journal until at least 150ms after the Log() call returns. If a test
returns while log messages are still in flight to be written, the logs
may attempt to be written after the TempDir has been cleaned up, leading
to spurious errors.
The logger read tests which interleave writing and reading have to
include explicit synchronization points to work reliably with this delay
in place. On the other hand, tests should not be required to sync the
logger explicitly before returning. Override the Close() method in the
test harness wrapper to wait for in-flight logs to be flushed to disk.

The Go race detector was detecting a data race when running the
TestLogRead/Follow/Concurrent test against the journald logging driver.
The race was in the test harness, specifically syncLogger. The waitOn

which is not concurrency-safe. Make it concurrency-safe using the same
patterns that are used in the log follower implementation to synchronize

The journald reader uses a timer to set an upper bound on how long to
wait for the final log message of a stopped container. However, the
timer channel is only received from in non-blocking select statements!
There isn't enough benefit of using a timer to offset the cost of having
to manage the timer resource. Setting a deadline and comparing the
current time is just as effective, without having to manage the

Commit 8b7af1d0f added some code to update the DNSNames of all
endpoints attached to a sandbox by loading a new instance of each
affected endpoints from the datastore through a call to
`Network.EndpointByID()`.
This method then calls `Network.getEndpointFromStore()`, that in
turn calls `store.GetObject()`, which then calls `cache.get()`,
which calls `o.CopyTo(kvObject)`. This effectively creates a fresh
new instance of an Endpoint. However, endpoints are already kept in
memory by Sandbox, meaning we now have two in-memory instances of
the same Endpoint.
As it turns out, libnetwork is built around the idea that no two objects
representing the same thing should leave in-memory, otherwise breaking
mutex locking and optimistic locking (as both instances will have a drifting
version tracking ID -- dbIndex in libnetwork parliance).
In this specific case, this bug materializes by container rename failing
when applied a second time for a given container. An integration test is
added to make sure this won't happen again.

Commit 21e50b89c9 added a label on the buildkit
worker to advertise the host-gateway-ip. This option can be either set by the
user in the daemon config, or otherwise defaults to the gateway-ip.
If no value is set by the user, discovery of the gateway-ip happens when
initializing the network-controller (`NewDaemon`, `daemon.restore()`).
However d222bf097c changed how we handle the
daemon config. As a result, the `cli.Config` used when initializing the
builder only holds configuration information form the daemon config
(user-specified or defaults), but is not updated with information set
by `NewDaemon`.
This patch adds an accessor on the daemon to get the current daemon config.
An alternative could be to return the config by `NewDaemon` (which should
likely be a _copy_ of the config).

Commit 8ae94cafa5 added a DNS resolution
of the `device` part of the volume option.
The previous way to resolve the passed hostname was to use `addr`
option, which was handled by the same code path as the `nfs` mount type.
The issue is that `addr` is also an SMB module option handled by kernel
and passing a hostname as `addr` produces an invalid argument error.
To fix that, restore the old behavior to handle `addr` the same way as
before, and only perform the new DNS resolution of `device` if there is
no `addr` passed.

This matcher was only used internally in the containerd implementation of
the image store. Un-export it, and make it a local utility in that package
to prevent external use.
This package was introduced in 1616a09b61
(v24.0), and there are no known external consumers of this package, so there
should be no need to deprecate / alias the old location.

When resolving names in swarm mode, services with exposed ports are
connected to user overlay network, ingress network, and local (docker_gwbridge)
networks. Name resolution should prioritize returning the VIP/IPs on user
overlay network over ingress and local networks.
Sandbox.ResolveName implemented this by taking the list of endpoints,
splitting the list into 3 separate lists based on the type of network
that the endpoint was attached to (dynamic, ingress, local), and then
creating a new list, applying the networks in that order.
This patch refactors that logic to use a custom sorter (sort.Interface),
which makes the code more transparent, and prevents iterating over the
list of endpoints multiple times.

Some configuration in a container depends on whether it has support for
IPv6 (including default entries for '::1' etc in '/etc/hosts').
Before this change, the container's support for IPv6 was determined by
whether it was connected to any IPv6-enabled networks. But, that can
change over time, it isn't a property of the container itself.
So, instead, detect IPv6 support by looking for '::1' on the container's
loopback interface. It will not be present if the kernel does not have
IPv6 support, or the user has disabled it in new namespaces by other
means.
Once IPv6 support has been determined for the container, its '/etc/hosts'
is re-generated accordingly.
The daemon no longer disables IPv6 on all interfaces during initialisation.
It now disables IPv6 only for interfaces that have not been assigned an
IPv6 address. (But, even if IPv6 is disabled for the container using the
sysctl 'net.ipv6.conf.all.disable_ipv6=1', interfaces connected to IPv6
networks still get IPv6 addresses that appear in the internal DNS. There's
more to-do!)

For some time, when adding an interface with no IPv6 address (an
interface to a network that does not have IPv6 enabled), we've been
disabling IPv6 on that interface.
As part of a separate change, I'm removing that logic - there's nothing
wrong with having IPv6 enabled on an interface with no routable address.
The difference is that the kernel will assign a link-local address.
TestAddRemoveInterface does this...
- Assign an IPv6 link-local address to one end of a veth interface, and
add it to a namespace.
- Add a bridge with no assigned IPv6 address to the namespace.
- Remove the veth interface from the namespace.
- Put the veth interface back into the namespace, still with an
explicitly assigned IPv6 link local address.
When IPv6 is disabled on the bridge interface, the test passes.
But, when IPv6 is enabled, the bridge gets a kernel assigned link-local
address.
Then, when re-adding the veth interface, the test generates an error in
'osl/interface_linux.go:checkRouteConflict()'. The conflict is between
the explicitly assigned fe80::2 on the veth, and a route for fe80::/64
belonging to the bridge.
So, in preparation for not-disabling IPv6 on these interfaces, use a
unique-local address in the test instead of link-local.
I don't think that changes the intent of the test.
With the change to not-always disable IPv6, it is possible to repro the
problem with a real container, disconnect and re-connect a user-defined
network with '--subnet fe80::/64' while the container's connected to an
IPv4 network. So, strictly speaking, that will be a regression.
But, it's also possible to repro the problem in master, by disconnecting
and re-connecting the fe80::/64 network while another IPv6 network is
connected. So, I don't think it's a problem we need to address, perhaps
other than by prohibiting '--subnet fe80::/64'.

Pasta is similar to slirp4netns but its port forwarder achieves better

It is still not faster than RootlessKit's `builtin` port driver, but unlike the
`builtin` port driver, pasta can retain source IP address information.

---------------|----------------|----------------|-----------------|--------|---------|--------------------------------------------
slirp4netns | builtin | Slow | Fast ✅ | ❌ | ✅ | Default in typical setup
vpnkit | builtin | Slow | Fast ✅ | ❌ | ✅ | Default when slirp4netns is not installed
slirp4netns | slirp4netns | Slow | Slow | ✅ | ✅ |
**pasta** | **implicit** | Slow | Fast ✅ | ✅ | ✅ | Experimental
lxc-user-nic | builtin | Fast ✅ | Slow | ❌ | ❌ | Experimental

"detach-netns" mode, which leaves the runtime in the host network namespace to

The new OCI-compatible archive export relies on the Descriptors returned
by the layer (`distribution.Describable` interface implementation).
The issue with that is that the `roLayer` and the `referencedCacheLayer`
types don't implement this interface. Implementing that interface for
them based on their `descriptor` doesn't work though, because that
descriptor is empty.
To workaround this issue, just create a new descriptor if the one

The container may have been running without health probes for an
indeterminate amount of time. The container may have become unhealthy in
the interim. We should probe it sooner than in steady-state, while also
giving it some leeway to recover from e.g. timed-out connections. This
is easy to achieve by probing the container like a freshly-started one.
The original author of health-checks came to the same conclusion; the
health monitor was reinitialized on live-restored containers before
v17.11.0, when health monitoring of live-restored containers was

The `ExecBackend.ContainerKill()` function was called before removing a build-
container.
This function is backed by `daemon.ContainerKill()` which, if no signal is passed,
performed a `daemon.Kill()`, using `SIGKILL` as signal. However, the
`ExecBackend.ContainerRm()` (backed by `daemonContainerRm()`), which is called
after this, is executed with the `ForceRemove` option set, which calls
`daemon.cleanupContainer()` with `ForceRemove` set, which also results in
`daemon.Kill()` being called:
1a0c15abbb/daemon/delete.go (L84-L95)
This makes the `ExecBackend.ContainerKill()` redundant, so removing this from
the interface.
While looking at this code, one (possible) race-condition was found in
`daemon.cleanupContainer()`, where `daemon.Kill()` could return a `errdefs.Conflict`

A check was added to the bridge driver to detect when it was called to
create the default bridge nw whereas a stale default bridge already
existed. In such case, the bridge driver was deleting the stale network
before re-creating it. This check was introduced in docker/libnetwork@6b158eac6a
to fix an issue related to newly introduced live-restore.
However, since commit docker/docker@ecffb6d58c,
the daemon doesn't even try to create default networks if there're
active sandboxes (ie. due to live-restore).
Thus, now it's impossible for the default bridge network to be stale and
to exists when the driver's CreateNetwork() method is called. As such,
the check introduced in the first commit mentioned above is dead code
and can be safely removed.

This hopefully makes the test less flakey (or removes any flake that
would be caused by the test itself).
1. Adds tail of cluster daemon logs when there is a test failure so we
can more easily see what may be happening
2. Scans the daemon logs to check if the key is rotated before
restarting the daemon. This is a little hacky but a little better
than assuming it is done after a hard-coded 3 seconds.
3. Cleans up the `node ls` check such that it uses a poll function

The Go 1.21.5 compiler has a bug: per-file language version override
directives do not take effect when instantiating generic functions which
have certain nontrivial type constraints. Consequently, a module-mode
project with Moby as a dependency may fail to compile when the compiler
incorrectly applies go1.16 semantics to the generic function call.
As the offending function is trivial and is only used in one place, work
around the issue by converting it to a concretely-typed function.

When mapping a port with the userland-proxy enabled, the daemon would
perform an "exec.LookPath" for every mapped port (which, in case of
a range of ports, would be for every port in the range).
This was both inefficient (looking up the binary for each port), inconsistent
(when running in rootless-mode, the binary was looked-up once), as well as
inconvenient, because a missing binary, or a mis-configureed userland-proxy-path
would not be detected daeemon startup, and not produce an error until starting
the container;
docker run -d -P nginx:alpine
4f7b6589a1680f883d98d03db12203973387f9061e7a963331776170e4414194

However, the container would still be created (but invalid);
docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
869f41d7e94f nginx:alpine "/docker-entrypoint.…" 10 seconds ago Created romantic_wiles
This patch changes how the userland-proxy is configured;
- The path of the userland-proxy is now looked up / configured at daemon
startup; this is similar to how the proxy is configured in rootless-mode.
- A warning is logged when failing to lookup the binary.
- If the daemon is configured with "userland-proxy" enabled, an error is
produced, and the daemon will refuse to start.
- The "proxyPath" argument for newProxyCommand() (in libnetwork/portmapper)
is now required to be set. It no longer looks up the executable, and
produces an error if no path was provided. While this change was not
required, it makes the daemon config the canonical source of truth, instead
of logic spread accross multiplee locations.
Some of this logic is a change of behavior, but these changes were made with
the assumption that we don't want to support;
- installing the userland proxy _after_ the daemon was started
- moving the userland proxy (or installing a proxy with a higher
preference in PATH)
With this patch:
Validating the config produces an error if the binary is not found:
dockerd --validate
WARN[2023-12-29T11:36:39.748699591Z] failed to lookup default userland-proxy binary error="exec: \"docker-proxy\": executable file not found in $PATH"
userland-proxy is enabled, but userland-proxy-path is not set
Disabling userland-proxy prints a warning, but validates as "OK":
dockerd --userland-proxy=false --validate

Speficying a non-absolute path produces an error:
dockerd --userland-proxy-path=docker-proxy --validate

Befor this patch, we would not validate this path, which would allow the daemon
to start, but fail to map a port;

The defer was set after the switch, but various code-paths inside the switch
could return with an error after the port was allocated / reserved, which
could result in those ports not being released.
This patch moves the defer into each individual branch of the switch to set
it immediately after succesfully reserving the port.
We can also remove a redundant ReleasePort from the cleanup function, as
it's only called if an error occurs, and the defers already take care of
that.
Note that the cleanup function was handling errors returned by ReleasePort,
but this function never returns an error, so it was fully redundant.

The semantics of an "anonymous" endpoint has always been weird: it was
set on endpoints which name shouldn't be taken into account when
inserting DNS records into libnetwork's `Controller.svcRecords` (and
into the NetworkDB). However, in that case the endpoint's aliases would
still be used to create DNS records; thus, making those "anonymous
endpoints" not so anonymous.

Calculate the IPv6 addreesses needed on a bridge, then reconcile them
with the addresses on an existing bridge by deleting then adding as
required.
(Previously, required addresses were added one-by-one, then unwanted
addresses were removed. This meant the daemon failed to start if, for
example, an existing bridge had address '2000:db8::/64' and the config
was changed to '2000:db8::/80'.)
IPv6 addresses are now calculated and applied in one go, so there's no
need for setupVerifyAndReconcile() to check the set of IPv6 addresses on
the bridge. And, it was guarded by !config.InhibitIPv4, which can't have
been right. So, removed its IPv6 parts, and added IPv4 to its name.
Link local addresses, the example given in the original ticket, are now
released when containers are stopped. Not releasing them meant that
when using an LL subnet on the default bridge, no container could be
started after a container was stopped (because the calculated address
could not be re-allocated). In non-default bridge networks using an
LL subnet, addresses leaked.
Linux always uses the standard 'fe80::/64' LL network. So, if a bridge
is configured with an LL subnet prefix that overlaps with it, a config
error is reported. Non-overlapping LL subnet prefixes are allowed.

This repository is not yet a module (i.e., does not have a `go.mod`). This
is not problematic when building the code in GOPATH or "vendor" mode, but
when using the code as a module-dependency (in module-mode), different semantics
are applied since Go1.21, which switches Go _language versions_ on a per-module,
per-package, or even per-file base.
A condensed summary of that logic [is as follows][1]:
- For modules that have a go.mod containing a go version directive; that
version is considered a minimum _required_ version (starting with the
go1.19.13 and go1.20.8 patch releases: before those, it was only a
recommendation).
- For dependencies that don't have a go.mod (not a module), go language
version go1.16 is assumed.
- Likewise, for modules that have a go.mod, but the file does not have a
go version directive, go language version go1.16 is assumed.
- If a go.work file is present, but does not have a go version directive,
language version go1.17 is assumed.
When switching language versions, Go _downgrades_ the language version,
which means that language features (such as generics, and `any`) are not
available, and compilation fails. For example:
# github.com/docker/cli/cli/context/store
/go/pkg/mod/github.com/docker/cli@v25.0.0-beta.2+incompatible/cli/context/store/storeconfig.go:6:24: predeclared any requires go1.18 or later (-lang was set to go1.16; check go.mod)
/go/pkg/mod/github.com/docker/cli@v25.0.0-beta.2+incompatible/cli/context/store/store.go:74:12: predeclared any requires go1.18 or later (-lang was set to go1.16; check go.mod)
Note that these fallbacks are per-module, per-package, and can even be
per-file, so _(indirect) dependencies_ can still use modern language
features, as long as their respective go.mod has a version specified.
Unfortunately, these failures do not occur when building locally (using
vendor / GOPATH mode), but will affect consumers of the module.
Obviously, this situation is not ideal, and the ultimate solution is to
move to go modules (add a go.mod), but this comes with a non-insignificant
risk in other areas (due to our complex dependency tree).
We can revert to using go1.16 language features only, but this may be
limiting, and may still be problematic when (e.g.) matching signatures
of dependencies.
There is an escape hatch: adding a `//go:build` directive to files that
make use of go language features. From the [go toolchain docs][2]:
> The go line for each module sets the language version the compiler enforces
> when compiling packages in that module. The language version can be changed
> on a per-file basis by using a build constraint.
>
> For example, a module containing code that uses the Go 1.21 language version
> should have a `go.mod` file with a go line such as `go 1.21` or `go 1.21.3`.
> If a specific source file should be compiled only when using a newer Go
> toolchain, adding `//go:build go1.22` to that source file both ensures that
> only Go 1.22 and newer toolchains will compile the file and also changes
> the language version in that file to Go 1.22.
This patch adds `//go:build` directives to those files using recent additions
to the language. It's currently using go1.19 as version to match the version
in our "vendor.mod", but we can consider being more permissive ("any" requires
go1.18 or up), or more "optimistic" (force go1.21, which is the version we
currently use to build).
For completeness sake, note that any file _without_ a `//go:build` directive
will continue to use go1.16 language version when used as a module.

A validation step was added to prevent the daemon from considering "logentries"

WARN[2023-12-12T21:53:23.879869881Z] Unable to locate plugin: logentries, retrying in 8s
But would ultimately be returned as an error to the user:
docker container create --name foo --log-driver=logentries nginx:alpine
Error response from daemon: error looking up logging plugin logentries: plugin "logentries" not found
With the additional validation step, an error is returned immediately:
docker container create --log-driver=logentries busybox
Error response from daemon: the logentries logging driver has been deprecated and removed
A migration step was added on container restore. Containers using the
"logentries" logging driver are migrated to use the "local" logging driver:
WARN[2023-12-12T22:38:53.108349297Z] migrated deprecated logentries logging driver container=4c9309fedce75d807340ea1820cc78dc5c774d7bfcae09f3744a91b84ce6e4f7 error="<nil>"
As an alternative to the validation step, I also considered using a "stub"
deprecation driver, however this would not result in an error when creating
the container, and only produce an error when starting:
docker container create --name foo --log-driver=logentries nginx:alpine
4c9309fedce75d807340ea1820cc78dc5c774d7bfcae09f3744a91b84ce6e4f7

Error response from daemon: failed to create task for container: failed to initialize logging driver: the logentries logging driver has been deprecated and removed

For containers, this validation is added in the backend (daemon). For services,
this was not sufficient, as SwarmKit would try to schedule the task, which
caused a close loop;

This commit switches our code to use semconv 1.21, which is the version matching
the OTEL modules, as well as the containerd code.
The BuildKit 0.12.x module currently uses an older version of the OTEL modules,
and uses the semconv 0.17 schema. Mixing schema-versions is problematic, but
we still want to consume BuildKit's "detect" package to wire-up other parts
of OTEL.
To align the versions in our code, this patch sets the BuildKit detect.Resource
with the correct semconv version.
It's worth noting that the BuildKit package has a custom "serviceNameDetector";
https://github.com/moby/buildkit/blob/v0.12.4/util/tracing/detect/detect.go#L153-L169
Whith is merged with OTEL's default resource:
https://github.com/moby/buildkit/blob/v0.12.4/util/tracing/detect/detect.go#L100-L107
There's no need to duplicate that code, as OTEL's `resource.Default()` already
provides this functionality:
- It uses fromEnv{} detector internally: https://github.com/open-telemetry/opentelemetry-go/blob/v1.19.0/sdk/resource/resource.go#L208
- fromEnv{} detector reads OTEL_SERVICE_NAME: https://github.com/open-telemetry/opentelemetry-go/blob/v1.19.0/sdk/resource/env.go#L53
This patch also removes uses of the httpconv package, which is no longer included
in semconv 1.21 and now an internal package. Removing the use of this package
means that hijacked connections will not have the HTTP attributes on the Moby
client span, which isn't ideal, but a limited loss that'd impact exec/attach.
The span itself will still exist, it just won't the additional attributes that
are added by that package.
Alternatively, the httpconv call COULD remain - it will not error and will send
syntactically valid spans but we would be mixing & matching semconv versions,
so won't be compliant.
Some parts of the httpconv package were preserved through a very minimal local
implementation; a variant of `httpconv.ClientStatus(resp.StatusCode))` is added
to set the span status (`span.SetStatus()`). The `httpconv` package has complex
logic for this, but mostly drills down to HTTP status range (1xx/2xx/3xx/4xx/5xx)
to determine if the status was successfull or non-successful (4xx/5xx).
The additional logic it provided was to validate actual status-codes, and to
convert "bogus" status codes in "success" ranges (1xx, 2xx) into an error. That
code seemed over-reaching (and not accounting for potential future _valid_
status codes). Let's assume we only get valid status codes.

Config serialization performed by the graphdriver implementation
maintained the distinction between an empty array and having no Cmd set.
With containerd integration we serialize the OCI types directly that use
the `omitempty` option which doesn't persist that distinction.
Considering that both values should have exactly the same semantics (no
cmd being passed) it should be fine if in this case the Cmd would be
null instead of an empty array.

Acquire the mutex in the help handler to synchronize access to the

We don't need C-style callback functions which accept a void* context
parameter: Go has closures. Drop the unnecessary httpHandlerCustom type
and refactor the diagnostic server handler functions into closures which
capture whatever context they need implicitly.
If the node leaves and rejoins a swarm, the cluster agent and its
associated NetworkDB are discarded and replaced with new instances. Upon
rejoin, the agent registers its NetworkDB instance with the diagnostic
server. These handlers would all conflict with the handlers registered
by the previous NetworkDB instance. Attempting to register a second
handler on a http.ServeMux with the same pattern will panic, which the
diagnostic server would historically deal with by ignoring the duplicate
handler registration. Consequently, the first NetworkDB instance to be
registered would "stick" to the diagnostic server for the lifetime of
the process, even after it is replaced with another instance. Improve
duplicate-handler registration such that the most recently-registered
handler for a pattern is used for all subsequent requests.

[security] Go 1.21.5 and Go 1.20.12 are released
Hello gophers,
We have just released Go versions 1.21.5 and 1.20.12, minor point releases.
These minor releases include 3 security fixes following the security policy:
- net/http: limit chunked data overhead
A malicious HTTP sender can use chunk extensions to cause a receiver
reading from a request or response body to read many more bytes from
the network than are in the body.
A malicious HTTP client can further exploit this to cause a server to
automatically read a large amount of data (up to about 1GiB) when a
handler fails to read the entire body of a request.
Chunk extensions are a little-used HTTP feature which permit including
additional metadata in a request or response body sent using the chunked
encoding. The net/http chunked encoding reader discards this metadata.
A sender can exploit this by inserting a large metadata segment with
each byte transferred. The chunk reader now produces an error if the
ratio of real body to encoded bytes grows too small.
Thanks to Bartek Nowotarski for reporting this issue.
This is CVE-2023-39326 and Go issue https://go.dev/issue/64433.
- cmd/go: go get may unexpectedly fallback to insecure git
Using go get to fetch a module with the ".git" suffix may unexpectedly
fallback to the insecure "git://" protocol if the module is unavailable
via the secure "https://" and "git+ssh://" protocols, even if GOINSECURE
is not set for said module. This only affects users who are not using
the module proxy and are fetching modules directly (i.e. GOPROXY=off).
Thanks to David Leadbeater for reporting this issue.
This is CVE-2023-45285 and Go issue https://go.dev/issue/63845.
- path/filepath: retain trailing \ when cleaning paths like \\?\c:\
Go 1.20.11 and Go 1.21.4 inadvertently changed the definition of the
volume name in Windows paths starting with \\?\, resulting in
filepath.Clean(\\?\c:\) returning \\?\c: rather than \\?\c:\ (among
other effects). The previous behavior has been restored.

[security] Go 1.21.4 and Go 1.20.11 are released
Hello gophers,
We have just released Go versions 1.21.4 and 1.20.11, minor point releases.
These minor releases include 2 security fixes following the security policy:
- path/filepath: recognize `\??\` as a Root Local Device path prefix.
On Windows, a path beginning with `\??\` is a Root Local Device path equivalent
to a path beginning with `\\?\`. Paths with a `\??\` prefix may be used to
access arbitrary locations on the system. For example, the path `\??\c:\x`
is equivalent to the more common path c:\x.
The filepath package did not recognize paths with a `\??\` prefix as special.
Clean could convert a rooted path such as `\a\..\??\b` into
the root local device path `\??\b`. It will now convert this
path into `.\??\b`.
`IsAbs` did not report paths beginning with `\??\` as absolute.
It now does so.
VolumeName now reports the `\??\` prefix as a volume name.
`Join(`\`, `??`, `b`)` could convert a seemingly innocent
sequence of path elements into the root local device path
`\??\b`. It will now convert this to `\.\??\b`.
This is CVE-2023-45283 and https://go.dev/issue/63713.
- path/filepath: recognize device names with trailing spaces and superscripts
The `IsLocal` function did not correctly detect reserved names in some cases:
- reserved names followed by spaces, such as "COM1 ".
- "COM" or "LPT" followed by a superscript 1, 2, or 3.
`IsLocal` now correctly reports these names as non-local.
This is CVE-2023-45284 and https://go.dev/issue/63713.

The daemon currently provides support for API versions all the way back
to v1.12, which is the version of the API that shipped with docker 1.0. On
Windows, the minimum supported version is v1.24.
Such old versions of the client are rare, and supporting older API versions
has accumulated significant amounts of code to remain backward-compatible
(which is largely untested, and a "best-effort" at most).
This patch updates the minimum API version to v1.24, which is the fallback
API version used when API-version negotiation fails. The intent is to start
deprecating older API versions, but no code is removed yet as part of this
patch, and a DOCKER_MIN_API_VERSION environment variable is added, which
allows overriding the minimum version (to allow restoring the behavior from
before this patch).
With this patch the daemon defaults to API v1.24 as minimum:

The `ContainerCreateConfig` and `ContainerRmConfig` structs are used for
options to be passed to the backend, and are not used in client code.
Thess struct currently is intended for internal use only (for example, the
`AdjustCPUShares` is an internal implementation details to adjust the container's
config when older API versions are used).
Somewhat ironically, the signature of the Backend has a nicer UX than that
of the client's `ContainerCreate` signature (which expects all options to
be passed as separate arguments), so we may want to update that signature
to be closer to what the backend is using, but that can be left as a future
exercise.
This patch moves the `ContainerCreateConfig` and `ContainerRmConfig` structs

I noticed this log being logged as an error, but the kill logic actually
proceeds after this (doing a "direct" kill instead). While usually containers
are expected to be exiting within the given timeout, I don't think this
needs to be logged as an error (an error is returned after we fail to
kill the container).

Both the `TestDaemonICCPing`, and `TestDaemonICCLinkExpose` test were introduced
in dd0666e64f. These tests called `iptables` with
the `-n` (`--numeric`) option, which prevents it from doing a reverse-DNS lookup
as an optimization.
However, the `-n` option did not have an effect to the `prot` column before
commit [da8ecc62dd765b15df84c3aa6b83dcb7a81d4ffa] (iptables < v1.8.9 or v1.8.8).
Newer versions, such as the iptables version shipping with Debian Woodworm do,
so we need to update the expected output for this version.
This patch removes the `-n` option, to keep the test more portable, also when
run non-containerized, and removes the use of regular expressions to check the
result, as these regular expressions were quite permissive (using `.*` wild-

Change the repo name used as for an intermediate image so it doesn't
try to mount from the image pushed by `TestBuildMultiStageImplicitPull`.
Before this patch, this test failed because the distribution.source
labels are not cleared between tests and the busybox content still has
the distribution.source label pointing to the `dockercli/testf`
repository which is no longer present in the test registry.
So both `dockercli/busybox` and `dockercli/testf` are equally valid
mount candidates for `dockercli/crossrepopush` and containerd algorithm
just happens to select the last one.

BaseFS is not serialized and is lost after an unclean shutdown. Unmount
method in the containerd image service implementation will not work
correctly in that case.
This patch will allow Unmount to restore the BaseFS if the target is
still mounted.
The reason it works with graphdrivers is that it doesn't directly
operate on BaseFS. It uses RWLayer, which is explicitly restored

This is purely cosmetic - if a non-default MTU is configured, the bridge
will have the default MTU=1500 until a container's 'veth' is connected

The graphdriver implementation sets the ModTime of all image content to
match the `Created` time from the image config, whereas the containerd's
archive export code just leaves it empty (zero).
Adjust the test in the case where containerd integration is enabled to
check if config file ModTime is equal to zero (UNIX epoch) instead.
This behaviour is not a part of the Docker Image Specification and the
intention behind introducing it was to make the `docker save` produce
the same archive regardless of the time it was performed.
It would also be a bit problematic with the OCI archive layout which can
contain multiple images referencing the same content.

DNS config is a property of each adapter on Windows, thus we've a
dedicated `EndpointOption` for that.
The list of `EndpointOption` that should be applied to a given endpoint
is built by `buildCreateEndpointOptions`. This function contains a
seemingly flawed condition that adds the DNS config _iff_:
1. the network isn't internal ;
2. no ports are published / exposed through another sandbox endpoint ;
While 1. does make sense, there's actually no justification for 2.,
hence this commit remove this part of the condition.
This logic flaw has been made obvious by 0fd0e82, but it was originally
introduced by d1e0a78. Commit and PR comments don't mention why this is
done like so. Most probably, this was overlooked both by the original
author and the PR reviewers.

The `buildCreateEndpointOptions` does a lot of things to build the list
of `libnetwork.EndpointOption` from the `EndpointSettings` spec. To skip
ports-related options, an early return was put in the middle of that
function body.
Early returns are generally great, but put in the middle of a 150-loc
long function that does a lot, they're just a potential footgun. And I'm
the one who pulled the trigger in 052562f. Since this commit, generic
options won't be applied to endpoints if there's already one with
exposed/published ports. As a consequence, only the first endpoint can
have a user-defined MAC address right now.
Instead of moving up the code line that adds generic options, a better
change IMO is to move ports-related options, and the early-return gating
those options, to a dedicated func to make `buildCreateEndpointOptions`
slightly easier to read and reason about.
There was actually one oddity in the original
`buildCreateEndpointOptions`: the early-return also gates the addition
of `CreateOptionDNS`. These options are Windows-specific; a comment is
added to explain that. But the oddity is really: why are we checking if
an endpoint with exposed / published ports joined this sandbox to decide
whether we want to configure DNS server on the endpoint's adapter? Well,
this early-return was most probably overlooked by the original author
and by reviewers at the time these options were added (in commit d1e0a78)
Let's fix that in a follow-up commit.

The forwarding database (fdb) of Linux VXLAN links are restricted to
entries with destination VXLAN tunnel endpoint (VTEP) address of a
single address family. Which address family is permitted is set when the
link is created and cannot be modified. The overlay network driver
creates VXLAN links such that the kernel only allows fdb entries to be
created with IPv4 destination VTEP addresses. If the Swarm is configured
with IPv6 advertise addresses, creating fdb entries for remote peers
fails with EAFNOSUPPORT (address family not supported by protocol).
Make overlay networks functional over IPv6 transport by configuring the
VXLAN links for IPv6 VTEPs if the local node's advertise address is an
IPv6 address. Make encrypted overlay networks secure over IPv6 transport

This test was rewritten from an integration-cli test in commit
68d9beedbe, and originally implemented in
f4942ed864, which rewrote it from a unit-
test to an integration test.
Originally, it would check for the raw JSON response from the daemon, and
check for individual fields to be present in the output, but after commit
0fd5a65428, `client.Info()` was used, and
now the response is unmarshalled into a `system.Info`.
The remainder of the test remained the same in that rewrite, and as a
result were were now effectively testing if a `system.Info` struct,
when marshalled as JSON would show all the fields (surprise: it does).
TL;DR; the test would even pass with an empty `system.Info{}` struct,
which didn't provide much coverage, as it passed without a daemon:
func TestInfoAPI(t *testing.T) {
// always shown fields
stringsToCheck := []string{
"ID",
"Containers",
"ContainersRunning",
"ContainersPaused",
"ContainersStopped",
"Images",
"LoggingDriver",
"OperatingSystem",
"NCPU",
"OSType",
"Architecture",
"MemTotal",
"KernelVersion",
"Driver",
"ServerVersion",
"SecurityOptions",
}
out := fmt.Sprintf("%+v", system.Info{})
for _, linePrefix := range stringsToCheck {
assert.Check(t, is.Contains(out, linePrefix))
}
}
This patch makes the test _slightly_ better by checking if the fields
are non-empty. More work is needed on this test though; currently it
uses the (already running) daemon, so it's hard to check for specific
fields to be correct (withouth knowing state of the daemon), but it's
not unlikely that other tests (partially) cover some of that. A TODO
comment was added to look into that (we should probably combine some
tests to prevent overlap, and make it easier to spot "gaps" as well).
While working on this, also moving the `SystemTime` into this test,
because that field is (no longer) dependent on "debug" state

This commit introduces a new integration test suite aimed at testing
networking features like inter-container communication, network
isolation, port mapping, etc... and how they interact with daemon-level
and network-level parameters.
So far, there's pretty much no tests making sure our networks are well
configured: 1. there're a few tests for port mapping, but they don't
cover all use cases ; 2. there're a few tests that check if a specific
iptables rule exist, but that doesn't prevent that specific iptables
rule to be wrong in the first place.
As we're planning to refactor how iptables rules are written, and change
some of them to fix known security issues, we need a way to test all
combinations of parameters. So far, this was done by hand, which is
particularly painful and time consuming. As such, this new test suite is
foundational to upcoming work.

a.Contains(b.Addr()) || b.Contains(a.Addr())
is functionally equivalent to
a.Overlaps(b)
The (netip.Prefix).Contains method works by masking the address with the
prefix's mask and testing whether the remaining most-significant bits
are equal to the same bits in the prefix. The (netip.Prefix).Overlaps
method works by masking the longer prefix to the length of the shorter
prefix and testing whether the remaining most-significant bits are
equal. This is equivalent to
shorterPrefix.Contains(longerPrefix.Addr()), therefore applying Contains
symmetrically to two prefixes will always yield the same result as
applying Overlaps to the two prefixes in either order.

Shutting down containers on Windows can take a long time (with hyper-v),
causing this test to be flaky; seen failing on windows 2022;
=== FAIL: github.com/docker/docker/integration/image TestSaveRepoWithMultipleImages (23.16s)
save_test.go:104: timeout waiting for container to exit
Looking at the test, we run a container only to commit it, and the test
does not make changes to the container's filesystem; it only runs a container
with a custom command (`true`).
Instead of running the container, we can _create_ a container and commit it;
this simplifies the tests, and prevents having to wait for the container to
exit (before committing).

When starting a daemon in debug mode (such as used in CI), many log-messages
are printed during startup. As a result, the log message indicating whether
graph-drivers or snapshotters are used may appear far separate from the
informational log about the daemon (and selected storage-driver).
The existing log-driver also unconditionally uses the legacy "graph-driver"
terminology, instead of the more generic "storage-driver".
This patch changes the log message shown during startup to use the generic
"graph-driver" as field, and adds a new field that indicates wheter we're
using snapshotters or graph-drivers.
Given that snapshotters will be the default at some point, an alternative
could be to include the _type_ of driver used, for example;
`io.containerd.snapshotter.v1`, which may continue to be relevant after
snapshotters become the default, and at which point (potentially) the
type of snapshotter becomes more relevant.

commit def549c8f6 passed through the context
to the daemon.ContainerStart function. As a result, restarting containers
no longer is an atomic operation, because a context cancellation could
interrupt the restart (between "stopping" and "(re)starting"), resulting
in the container being stopped, but not restarted.
Restarting a container, or more factually; making a successful request on
the `/containers/{id]/restart` endpoint, should be an atomic operation.
This patch uses a context.WithoutCancel for restart requests.
It's worth noting that daemon.containerStop already uses context.WithoutCancel,
so in that function, we'll be wrapping the context twice, but this should
likely not cause issues (just redundant for this code-path).
Before this patch, starting a container that bind-mounts the docker socket,
then restarting itself from within the container would cancel the restart
operation. The container would be stopped, but not started after that:
docker run -dit --name myself -v /var/run/docker.sock:/var/run/docker.sock docker:cli sh
docker exec myself sh -c 'docker restart myself'
docker ps -a

The existing pkg/archive unit tests are primarily round-trip tests which
assert that pkg/archive produces tarballs which pkg/archive can unpack.
While these tests are effective at catching regressions in archiving or
unarchiving, they have a blind spot for regressions in compatibility
with the rest of the ecosystem. For example, a typo in the capabilities
extended attribute constant would result in subtly broken image layer
tarballs, but the existing tests would not catch the bug if both the
archiving and unarchiving implementations have the same typo.
Extend the test for archiving an overlay filesystem layer to assert that
the overlayfs style whiteouts (extended attributes and device files) are
transformed into AUFS-style whiteouts (magic file names).

The logic to rename an endpoint includes code which would synchronize
the renamed service records to peers through the distributed datastore.
It would trigger the remote peers to pick up the rename by touching a
datastore object which remote peers would have subscribed to events on.
The code also asserts that the local peer is subscribed to updates on
the network associated with the endpoint, presumably as a proxy for
asserting that the remote peers would also be subscribed.

When the default bridge is disabled by setting dockerd's `--bridge=none`
option, the daemon still creates a sandbox for containers with no
network attachment specified. In that case `NetworkDisabled` will be set
to true.
However, currently the `releaseNetwork` call will early return if
NetworkDisabled is true. Thus, these sandboxes won't be deleted until
the daemon is restarted. If a high number of such containers are

[security] Go 1.21.3 and Go 1.20.10 are released
Hello gophers,
We have just released Go versions 1.21.3 and 1.20.10, minor point releases.
These minor releases include 1 security fixes following the security policy:
- net/http: rapid stream resets can cause excessive work
A malicious HTTP/2 client which rapidly creates requests and
immediately resets them can cause excessive server resource consumption.
While the total number of requests is bounded to the
http2.Server.MaxConcurrentStreams setting, resetting an in-progress
request allows the attacker to create a new request while the existing
one is still executing.
HTTP/2 servers now bound the number of simultaneously executing
handler goroutines to the stream concurrency limit. New requests
arriving when at the limit (which can only happen after the client
has reset an existing, in-flight request) will be queued until a
handler exits. If the request queue grows too large, the server
will terminate the connection.
This issue is also fixed in golang.org/x/net/http2 v0.17.0,
for users manually configuring HTTP/2.
The default stream concurrency limit is 250 streams (requests)
per HTTP/2 connection. This value may be adjusted using the
golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams
setting and the ConfigureServer function.
This is CVE-2023-39325 and Go issue https://go.dev/issue/63417.

"//line" directives can be used to bypass the restrictions on "//go:cgo_"
directives, allowing blocked linker and compiler flags to be passed during

running "go build". The line directive requires the absolute path of the file in

So far, internal networks were only isolated from the host by iptables
DROP rules. As a consequence, outbound connections from containers would
timeout instead of being "rejected" through an immediate ICMP dest/port
unreachable, a TCP RST or a failing `connect` syscall.
This was visible when internal containers were trying to resolve a
domain that don't match any container on the same network (be it a truly
"external" domain, or a container that don't exist/is dead). In that
case, the embedded resolver would try to forward DNS queries for the
different values of resolv.conf `search` option, making DNS resolution
slow to return an error, and the slowness being exacerbated by some libc
implementations.
This change makes `connect` syscall to return ENETUNREACH, and thus
solves the broader issue of failing fast when external connections are
attempted.

split the function, but let's keep that for a future exercise.
- name the `ipv6Miss` output variable. The "ipv6 miss" logic is rather

giving the variable a name to make it more apparent what it is.

This function was used to check if the network is a multi-host, swarm-scoped
network. Part of this check involved a check whether the cluster-agent was
present.
In all places where this function was used, the next step after checking if
the network was "cluster eligible", was to get the agent, and (again) check
if it was not nil.
This patch rewrites the isClusterEligible utility into a clusterAgent utility,
which both checks if the network is cluster-eligible, and returns the agent
(if set). For convenience, an "ok" bool is added, which callers can use to
return early (although just checking for nilness would likely have been
sufficient).
Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
This removes redundant nil-checks in Endpoint.deleteServiceInfoFromCluster
and Endpoint.addServiceInfoToCluster.
These functions return early if the network is not ["cluster eligible"][1],
and the function used for that (`Network.isClusterEligible`) requires the
[agent to not be `nil`][2].
This check moved around a few times ([3][3], [4][4]), but was originally
added in [libnetwork 1570][5] which, among others, tried to avoid a nil-pointer
exception reported in [moby 28712][6], which accessed the `Controller.agent`
[without locking][7]. That issue was addressed by adding locks, adding a
`Controller.getAgent` accessor, and updating deleteServiceInfoFromCluster
to use a local var. It also sprinkled this `nil` check to be on the safe
side, but as `Network.isClusterEligible` already checks for the agent
to not be `nil`, this should not be redundant.

We try to perform API-version negotiation as lazy as possible (and only execute
when we are about to make an API request). However, some code requires API-version
dependent handling (to set options, or remove options based on the version of the
API we're using).
Currently this code depended on the caller code to perform API negotiation (or
to configure the API version) first, which may not happen, and because of that
we may be missing options (or set options that are not supported on older API
versions).
This patch:
- splits the code that triggered API-version negotiation to a separate
Client.checkVersion() function.
- updates NewVersionError to accept a context
- updates NewVersionError to perform API-version negotiation (if enabled)
- updates various Client functions to manually trigger API-version negotiation

The ability to read these files may offer a power-based sidechannel

[949dd0104c496fa7c14991a23c03c62e44637e71][2] by restricting read access
to root. However, since many containers run as root, this is not
sufficient for our use case.
While untrusted code should ideally never be run, we can add some
defense in depth here by masking out the device class by default.
[Other mechanisms][3] to access this hardware exist, but they should not
be accessible to a container due to other safeguards in the

Error check in defer block used wrong error variable which is always nil
if the flow reaches the defer. This caused the `newProcess.Kill` to be

Although this only happens in Exec (as Start does overwrite the error),
this also adjusts the Start to also use the returned error to avoid this

When the daemon process or the host running it is abruptly terminated,
the layer metadata file can become inconsistent on the file system.
Specifically, `link` and `lower` files may exist but be empty, leading
to overlay mounting errors during layer extraction, such as:
"failed to register layer: error creating overlay mount to <path>:
too many levels of symbolic links."
This commit introduces the use of `AtomicWriteFile` to ensure that the
layer metadata files contain correct data when they exist on the file system.

Fixes#18864, #20648, #33561, #40901.
[This GH comment][1] makes clear network name uniqueness has never been
enforced due to the eventually consistent nature of Classic Swarm
datastores:
> there is no guaranteed way to check for duplicates across a cluster of
> docker hosts.
And this is further confirmed by other comments made by @mrjana in that
same issue, eg. [this one][2]:
> we want to adopt a schema which can pave the way in the future for a
> completely decentralized cluster of docker hosts (if scalability is
> needed).
This decentralized model is what Classic Swarm was trying to be. It's
been superseded since then by Docker Swarm, which has a centralized
control plane.
To circumvent this drawback, the `NetworkCreate` endpoint accepts a
`CheckDuplicate` flag. However it's not perfectly reliable as it won't
catch concurrent requests.
Due to this design decision, API clients like Compose have to implement
workarounds to make sure names are really unique (eg.
docker/compose#9585). And the daemon itself has seen a string of issues
due to that decision, including some that aren't fixed to this day (for
instance moby/moby#40901):
> The problem is, that if you specify a network for a container using
> the ID, it will add that network to the container but it will then
> change it to reference the network by using the name.
To summarize, this "feature" is broken, has no practical use and is a
source of pain for Docker users and API consumers. So let's just remove
it for _all_ API versions.

and the crypto/tls, go/types, net/http, and path/filepath packages. See the
Go 1.20.8 milestone on our issue tracker for details:

From the security mailing:
[security] Go 1.21.1 and Go 1.20.8 are released
Hello gophers,
We have just released Go versions 1.21.1 and 1.20.8, minor point releases.
These minor releases include 4 security fixes following the security policy:
- cmd/go: go.mod toolchain directive allows arbitrary execution
The go.mod toolchain directive, introduced in Go 1.21, could be leveraged to
execute scripts and binaries relative to the root of the module when the "go"
command was executed within the module. This applies to modules downloaded using
the "go" command from the module proxy, as well as modules downloaded directly
using VCS software.
Thanks to Juho Nurminen of Mattermost for reporting this issue.
This is CVE-2023-39320 and Go issue https://go.dev/issue/62198.
- html/template: improper handling of HTML-like comments within script contexts
The html/template package did not properly handle HMTL-like "<!--" and "-->"
comment tokens, nor hashbang "#!" comment tokens, in <script> contexts. This may
cause the template parser to improperly interpret the contents of <script>
contexts, causing actions to be improperly escaped. This could be leveraged to
perform an XSS attack.
Thanks to Takeshi Kaneko (GMO Cybersecurity by Ierae, Inc.) for reporting this
issue.
This is CVE-2023-39318 and Go issue https://go.dev/issue/62196.
- html/template: improper handling of special tags within script contexts
The html/template package did not apply the proper rules for handling occurrences
of "<script", "<!--", and "</script" within JS literals in <script> contexts.
This may cause the template parser to improperly consider script contexts to be
terminated early, causing actions to be improperly escaped. This could be
leveraged to perform an XSS attack.

polling for it to be running (which likely would never happen).

To fix that: 1. the condition under what the container's mac-address is
applied is updated to also match the full ID; 2. the network mode is
normalized to a full ID when it's only a partial one.

- The `Version` field was not used for any purpose, other than a debug log
- The `X-Docker-Registry-Version` header was part of the registry v1 spec,
however, as we're not using the `Version` field, we don't need the
header for anything.
- The `X-Docker-Registry-Config` header was only set by the mock registry;
there's no code consuming it, so we don't need to mock it (even if an
actual v1 registry / search API would return it).
It's also worth noting that we never call the `_ping` endpoint when using
Docker Hub's search API, and Docker Hub does not even implement the `_ping`
endpoint;

There is no meaningful distinction between driverapi.Registerer and
drvregistry.DriverNotifyFunc. They are both used to register a network
driver with an interested party. They have the same function signature.
The only difference is that the latter could be satisfied by an
anonymous closure. However, in practice the only implementation of
drvregistry.DriverNotifyFunc is the
(*libnetwork.Controller).RegisterDriver method. This same method also
makes the libnetwork.Controller type satisfy the Registerer interface,
therefore the DriverNotifyFunc type is redundant. Change
drvregistry.Networks to notify a Registerer and drop the
DriverNotifyFunc type.

On startup all local volumes were unmounted as a cleanup mechanism for
the non-clean exit of the last engine process.
This caused live-restored volumes that used special volume opt mount
flags to be broken. While the refcount was restored, the _data directory
was just unmounted, so all new containers mounting this volume would
just have the access to the empty _data directory instead of the real
volume.
With this patch, the mountpoint isn't unmounted. Instead, if the volume
is already mounted, just mark it as mounted, so the next time Mount is
called only the ref count is incremented, but no second attempt to mount
it is performed.

This field was used when the code supported both "v1" and "v2" registries.
We no longer support v1 registries, and the only v1 endpoint that's still
used is for the legacy "search" endpoint, which does not use the APIEndpoint
type.
As no code is using this field, and the value will always be set to "v2",
we can deprecated the Version field.
I'm keeping this field for 1 release, to give notice to any potential
external consumer, after which we can delete it.

First, remove the loop over `apiVersions`. The `apiVersions` map has two
entries (`APIVersion1 => "v1"`, and `APIVersion2 => "v2"`), and `APIVersion1`
is skipped, which means that the loop effectively translates to;
if apiVersionStr == "v2" {
return "", invalidParamf("unsupported V1 version path %s", apiVersionStr)
}
Which leaves us with "anything else" being returned as-is.
This patch removes the loop, and replaces the remaining handling to check
for the "v2" suffix to produce an error, or to strip the "v1" suffix.

This method is not part of any interface, and identical to Endpoint.Iface,
but one returns an Interface-type (driverapi.InterfaceInfo) and the other
returns a concrete type (EndpointInterface).
Interface-matching should generally happen on the receiver side, and this
function was only used in a single location, and passed as argument to
Driver.CreateEndpoint, which already matches the interface by accepting
a driverapi.InterfaceInfo.

While working on this code, I noticed that there's currently an issue
with userns enabled. When userns is enabled, joining another container's
namespace must also join its user-namespace.
However, a container can only be in a single user namespace, so if a
container joins namespaces from multiple containers, latter user-namespaces
overwrite former ones.
We must add validation for this, but in the meantime, add notes / todo's.

the path, and the underlying error that occurred.

This function didn't need the whole container, only its ID, so let's
use that as argument. This also makes it consistent with getIpcContainer.
Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
`Daemon.getPidContainer()` was wrapping the error-message with a message
("cannot join PID of a non running container") that did not reflect the
actual reason for the error; `Daemon.GetContainer()` could either return
an invalid parameter (invalid / empty identifier), or a "not found" error
if the specified container-ID could not be found.
In the latter case, we don't want to return a "not found" error through
the API, as this would indicate that the container we're _starting_ was
not found (which is not the case), so we need to convert the error into
an `errdefs.ErrInvalidParameter` (the container-ID specified for the PID
namespace is invalid if the container doesn't exist).
This logic is similar to what we do for IPC namespaces. which received
a similar fix in c3d7a0c603.
This patch updates the error-types, and moves them into the getIpcContainer
and getPidContainer container functions, both of which should return
an "invalid parameter" if the container was not found.
It's worth noting that, while `WithNamespaces()` may return an "invalid
parameter" error, the `start` endpoint itself may _not_ be. as outlined
in commit bf1fb97575, starting a container
that has an invalid configuration should be considered an internal server
error, and is not an invalid _request_. However, for uses other than
container "start", `WithNamespaces()` should return the correct error
to allow code to handle it accordingly.

So it looks like the removal fails because we couldn't kill the container
because it was already stopped, which may be a race condition where the first
check shows the container to be running (but may already be in process to be
removed or killed. In either case, we probably shouldn't fail the removal if

Currently, IPAM config is never validated by the API. Some checks
are done by the CLI, but they're not exhaustive. And some of these
misconfigurations might be caught early by libnetwork (ie. when the
network is created), and others only surface when connecting a container
to a misconfigured network. In both cases, the API would return a 500.
Although the `NetworkCreate` endpoint might already return warnings,
these are never displayed by the CLI. As such, it was decided during a

This functionality has been replaced with Controller.GetSandbox, and is
no longer used anywhere.
This patch removes:
- the Controller.WalkSandboxes method
- the SandboxContainerWalker SandboxWalker
- the SandboxWalker type
Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
Various parts of the code were using "walkers" to iterate over the
controller's sandboxes, and the only condition for all of them was
to find the sandbox for a given container-ID. Iterating over all
sandboxes was also sub-optimal, because on Windows, the ContainerID
is used as Sandbox-ID, which can be used to lookup the sandbox from
the "sandboxes" map on the controller.
This patch implements a GetSandbox method on the controller that
looks up the sandbox for a given container-ID, using the most optimal
approach (depending on the platform).
The new method can return errors for invalid (empty) container-IDs, and
a "not found" error to allow consumers to detect non-existing sandboxes,
or potentially invalid IDs.
This new method replaces the (non-exported) Daemon.getNetworkSandbox(),
which was only used internally, in favor of directly accessing the
controller's method.

This is something that stood out to me: removing the intermediate
container is part of a build step, but unlike the other output from
the build, wasn't indented (and prefixed with `--->`) to be shown
as part of the build.
This patch adds the `--->` prefix, to make it clearer what step the
removal was part of.
While at it, I also updated the message itself: this output is printed
_after_ the intermediate container has been removed, so we may as well
make it match reality, so I changed "removing" to "removed".

This function was added in 36fd9d02be
(libnetwork: ce6c6e8c35),
because there were multiple places where a DNS response was created,
which had to use the same options. However, new "common" options were
added since, and having it in a function separate from the other (also
common) options was just hiding logic, so let's remove it.
What the above probably _should_ have done was to create a common utility
to create a DNS response (as all other options are shared as well). This
was actually done in 0c22e1bd07 (libnetwork:
be3531759b),
which added a `createRespMsg` utility, but missed that it could be used
for both cases.

- removes the setCommonFlags function

It's used in various defers, but was using `err` as name, which can be
confusing, and increases the risk of accidentally shadowing the error.
This patch:
- introduces a `retErr` output variable, to be used in defer statements.
- explicitly changes some `err` uses to locally-scoped variables.
- moves some variable definitions closer to where they're used (where possible).
While working on this change, there was one point in the code where
error handling was ambiguous. I added a note for that, in case this
was not a bug:
> This code was previously assigning the error to the global "err"
> variable (before it was renamed to "retErr"), but in case of a
> "MaskableError" did not *return* the error:
> b325dcbff6/libnetwork/controller.go (L566-L573)
>
> Depending on code paths further down, that meant that this error
> was either overwritten by other errors (and thus not handled in
> defer statements) or handled (if no other code was overwriting it.
>
> I suspect this was a bug (but possible without effect), but it could
> have been intentional. This logic is confusing at least, and even
> more so combined with the handling in defer statements that check for

This goroutine was added in c458bca6dc, and
looks for errors from the wait channel. If no error is returned, it attempts
to start the container, and *updates* the error if a failure happened while
doing so, so that the code below it can update the container's status, and
perform auto-remove (if set for the container).
However, due to the formatting of the code, it was easy to overlook that
the "err" variable was not local to the "if" statement.

this is not a local "err" variable, and adds a code-comment explaining the

Removing this type, because:
- containerNotModifiedError is not an actual error, and abstracting it away
was hiding some of these details. It also wasn't used as a sentinel error
anywhere, so doesn't have to be its own type.
- Defining a type just to toggle the error-message between "not running"
and "not stopped" felt a bit over-the-top, as each variant was only used once.
- So "it only had one job", and it didn't even do that right; it produced

Check the preferredPool first, as other checks could be doing more
(such as locking, or validating / parsing). Also adding a note, as
it's unclear why we're ignoring invalid pools here.
The "invalid" conditions was added in [libnetwork#1095][1], which
moved code to reduce os-specific dependencies in the ipam package,
but also introduced a types.IsIPNetValid() function, which considers
"0.0.0.0/0" invalid, and added it to the condition to return early.
Unfortunately review does not mention this change, so there's no
context why. Possibly this was done to prevent errors further down
the line (when checking for overlaps), but returning an error here
instead would likely have avoided that as well, so we can only guess.
To make this code slightly more transparent, this patch also inlines
the "types.IsIPNetValid" function, as it's not used anywhere else,
and inlining it makes it more visible.

Partially revert commit 94b880f.
The CheckDuplicate field has been introduced in commit 2ab94e1. At that
time, this check was done in the network router. It was then moved to
the daemon package in commit 3ca2982. However, commit 94b880f duplicated
the logic into the network router for no apparent reason. Finally,
commit ab18718 made sure a 409 would be returned instead of a 500.
As this logic is first done by the daemon, the error -> warning
conversion can't happen because CheckDuplicate has to be true for the
daemon package to return an error. If it's false, the daemon proceed
with the network creation, set the Warning field of its return value and
return no error.
Thus, the CheckDuplicate logic in the api is removed and
libnetwork.NetworkNameError now implements the ErrConflict interface.

During review, it was decided to remove `LimitNOFILE` from `docker.service` to rely on the systemd v240 implicit default of `1024:524288`. On supported platforms with systemd prior to v240, packagers will patch the service with an explicit `LimitNOFILE=1024:524288`.
- `1024` soft limit is an implicit default, avoiding unexpected breakage. Software that needs a higher limit should request to raise the soft limit for its process.
- `524288` hard limit is an implicit default since systemd v240 and is adequate for most processes (_half of the historical limit from `fs.nr_open` of `1048576`_), while 4096 is the implicit default from the kernel (often too low). Individual containers can be started with `--ulimit` when a larger hard limit is required.
- The hard limit may not exceed `fs.nr_open` (_which a value of `infinity` will resolve to_). On most systems with systemd v240 or newer, this will resolve to an excessive size of 2^30 (over 1 billion).
- When set to `infinity` (usually as the soft limit) software may experience significantly increased resource usage, resulting in a performance regression or runtime failures that are difficult to troubleshoot.
- OpenRC current config approach lacks support for different soft/hard limits being set as it adjusts additional limits and `ulimit` does not support mixed usage of `-H` + `-S`. A soft limit of `524288` is not ideal, but 2^19 is much less overhead than 2^30, whilst a hard limit of 4096 would be problematic for Docker.

These tests were made parallel to speed up the execution, but this
turned out to be flaky, because they mutate some shared state.
The tests use shared `storage` variable without any synchronization.
However, adding synchronization is not enough in all cases, some tests
register the same plugin, so they can't be run in parallel to each
other.
This commit adds the synchronization around `storage` variable
modification and removes parallel from the tests where it's not enough.

Includes a fix for CVE-2023-29409
go1.20.7 (released 2023-08-01) includes a security fix to the crypto/tls
package, as well as bug fixes to the assembler and the compiler. See the
Go 1.20.7 milestone on our issue tracker for details:

From the mailing list announcement:
[security] Go 1.20.7 and Go 1.19.12 are released
Hello gophers,
We have just released Go versions 1.20.7 and 1.19.12, minor point releases.
These minor releases include 1 security fixes following the security policy:
- crypto/tls: restrict RSA keys in certificates to <= 8192 bits
Extremely large RSA keys in certificate chains can cause a client/server
to expend significant CPU time verifying signatures. Limit this by
restricting the size of RSA keys transmitted during handshakes to <=
8192 bits.
Based on a survey of publicly trusted RSA keys, there are currently only
three certificates in circulation with keys larger than this, and all
three appear to be test certificates that are not actively deployed. It
is possible there are larger keys in use in private PKIs, but we target
the web PKI, so causing breakage here in the interests of increasing the
default safety of users of crypto/tls seems reasonable.
Thanks to Mateusz Poliwczak for reporting this issue.

The is-automated field is being deprecated by Docker Hub's search API,
and will always be set to "false" in future.
This patch deprecates the field and related filter for the Engine's API.
In future, the `is-automated` filter will no longer yield any results
when searching for `is-automated=true`, and will be ignored when
searching for `is-automated=false`.
Given that this field is deprecated by an external API, the deprecation
will not be versioned, and will apply to any API version.

IPv4AddrNoMatchError and IPv6AddrNoMatchError are currently implementing
BadRequestError. They are returned in two cases, and none are due to a
bad user request:
- When calling daemon's CreateNetwork route, if the bridge's IPv4
address or none of the bridge's IPv6 addresses match what's requested.
If that happens, there's a big issue somewhere in libnetwork or the
kernel.
- When restoring a network, for the same reason. In that case, the

Go 1.15.7 contained a security fix for CVE-2021-3115, which allowed arbitrary
code to be executed at build time when using cgo on Windows.
This issue was not limited to the go command itself, and could also affect binaries
that use `os.Command`, `os.LookPath`, etc.
From the related blogpost (https://blog.golang.org/path-security):
> Are your own programs affected?
>
> If you use exec.LookPath or exec.Command in your own programs, you only need to
> be concerned if you (or your users) run your program in a directory with untrusted
> contents. If so, then a subprocess could be started using an executable from dot
> instead of from a system directory. (Again, using an executable from dot happens
> always on Windows and only with uncommon PATH settings on Unix.)
>
> If you are concerned, then we’ve published the more restricted variant of os/exec
> as golang.org/x/sys/execabs. You can use it in your program by simply replacing
At time of the go1.15 release, the Go team considered changing the behavior of
`os.LookPath()` and `exec.LookPath()` to be a breaking change, and made the
behavior "opt-in" by providing the `golang.org/x/sys/execabs` package as a
replacement.
However, for the go1.19 release, this changed, and the default behavior of
`os.LookPath()` and `exec.LookPath()` was changed. From the release notes:
https://go.dev/doc/go1.19#os-exec-path
> Command and LookPath no longer allow results from a PATH search to be found
> relative to the current directory. This removes a common source of security
> problems but may also break existing programs that depend on using, say,
> exec.Command("prog") to run a binary named prog (or, on Windows, prog.exe)
> in the current directory. See the os/exec package documentation for information
> about how best to update such programs.
>
> On Windows, Command and LookPath now respect the NoDefaultCurrentDirectoryInExePath
> environment variable, making it possible to disable the default implicit search
> of “.” in PATH lookups on Windows systems.
A result of this change was that registering the daemon as a Windows service
no longer worked when done from within the directory of the binary itself:
C:\> cd "Program Files\Docker\Docker\resources"
C:\Program Files\Docker\Docker\resources> dockerd --register-service
exec: "dockerd": cannot run executable found relative to current directory
Note that using an absolute path would work around the issue:
C:\Program Files\Docker\Docker>resources\dockerd.exe --register-service
This patch changes `registerService()` to use `os.Executable()`, instead of
depending on `os.Args[0]` and `exec.LookPath()` for resolving the absolute
path of the binary.

IPv6 ipt rules are exactly the same as IPv4 rules, although both
protocol don't use the same networking model. This has bad consequences,
for instance: 1. the current v6 rules disallow Neighbor
Solication/Advertisement ; 2. multicast addresses can't be used ; 3.
link-local addresses are blocked too.
To solve this, this commit changes the following rules:
```
-A DOCKER-ISOLATION-STAGE-1 ! -s fdf1:a844:380c:b247::/64 -o br-21502e5b2c6c -j DROP
-A DOCKER-ISOLATION-STAGE-1 ! -d fdf1:a844:380c:b247::/64 -i br-21502e5b2c6c -j DROP
```
into:
```
-A DOCKER-ISOLATION-STAGE-1 ! -s fdf1:a844:380c:b247::/64 ! -i br-21502e5b2c6c -o br-21502e5b2c6c -j DROP
-A DOCKER-ISOLATION-STAGE-1 ! -d fdf1:a844:380c:b247::/64 -i br-21502e5b2c6c ! -o br-21502e5b2c6c -j DROP
```
These rules only limit the traffic ingressing/egressing the bridge, but
not traffic between veth on the same bridge.
Note that, the Kernel takes care of dropping invalid IPv6 packets, eg.
loopback spoofing, thus these rules don't need to be more specific.

Make the function return the constructed network.IPAM instead of applying
it to a network struct, and rename it to "buildIPAMResources".
Rewrite the function itself:
- Use struct-literals where possible to make it slightly more readable.
- Use a boolean (hasIPv4Config, hasIPv6Config) for both IPv4 and IPv6 to
check whether the IPAM-info needs to be added. This makes the logic the
same for both, and makes the processing order-independent. This also
allows for the `network.IpamInfo()` call to be skipped if it's not needed.
- Change order of "ipv4 config / ipv4 info" and "ipv6 config / ipv4 info"
blocks to make it slightly clearer (and to allow skipping the forementioned
call to `network.IpamInfo()`).

The rootChain variable that the Key function references is a
package-global slice. As the append() built-in may append to the slice's
backing array in place, it is theoretically possible for the temporary
slices in concurrent Key() calls to share the same backing array, which
would be a data race. Thankfully in my tests (on Go 1.20.6)
cap(rootChain) == len(rootChain)
held true, so in practice a new slice is always allocated and there is
no race. But that is a very brittle assumption to depend upon, which
could blow up in our faces at any time without warning. Rewrite the
implementation in a way which cannot lead to data races.

arrangeUserFilterRule uses the package-level [`ctrl` variable][1], which
holds a reference to a controller instance. This variable is set by
[`setupArrangeUserFilterRule()`][2], which is called when initialization
a controller ([`libnetwork.New`][3]).
In normal circumstances, there would only be one controller, created during
daemon startup, and the instance of the controller would be the same as
the controller that `NewNetwork` is called from, but there's no protection
for the `ctrl` variable, and various integration tests create their own
controller instance.
The global `ctrl` var was introduced in [54e7900fb89b1aeeb188d935f29cf05514fd419b][4],
with the assumption that [only one controller could ever exist][5].
This patch tries to reduce uses of the `ctrl` variable, and as we're calling
this code from inside a method on a specific controller, we inline the code
and use that specific controller instead.

This function was added in libnetwork through 50964c9948
and, based on the name of the function and its signature, I think it
was meant to be a test. This patch refactors it to be one.
Changing it into a test made it slightly broken:
go test -v -run TestErrorInterfaces
=== RUN TestErrorInterfaces
errors_test.go:15: Failed to detect err network not found is of type BadRequestError. Got type: libnetwork.ErrNoSuchNetwork
errors_test.go:15: Failed to detect err endpoint not found is of type BadRequestError. Got type: libnetwork.ErrNoSuchEndpoint
errors_test.go:42: Failed to detect err unknown driver "" is of type ForbiddenError. Got type: libnetwork.NetworkTypeError
errors_test.go:42: Failed to detect err unknown network id is of type ForbiddenError. Got type: *libnetwork.UnknownNetworkError
errors_test.go:42: Failed to detect err unknown endpoint id is of type ForbiddenError. Got type: *libnetwork.UnknownEndpointError
--- FAIL: TestErrorInterfaces (0.00s)
FAIL
This was because some errors were tested twice, but for the wrong type
(`NetworkTypeError`, `UnknownNetworkError`, `UnknownEndpointError`).
Moving them to the right test left no test-cases for `types.ForbiddenError`,
so I added `ActiveContainerError` to not make that part of the code feel lonely.
Other failures were because some errors were changed from `types.BadRequestError`
to a `types.NotFoundError` error in commit ba012a703a,
so I moved those to the right part.

commit ffd75c2e0c updated this function to

arrangeUserFilterRule to log the failure as a warning, but continue with
the next iptables version.

These functions were mostly identical, except for iptables being enabled
by default (unless explicitly disabled by config).
Rewrite the function to a enabledIptablesVersions, which returns the list
of iptables-versions that are enabled for the controller. This prevents
having to acquire a lock twice, and simplifies arrangeUserFilterRule, which
can now just iterate over the enabled versions.
Also moving this function to a linux-only file, as other platforms don't have
the iptables types defined.

insecure-registries supports using CIDR notation, however, buildkit in
moby was not respecting these. We can update the RegistryHosts function
to support this by inserting the correct host into the lookup map if
it's explicitly marked as insecure.
Signed-off-by: Justin Chadwell <me@jedevc.com>
The RegistryHosts lookup function is used by both BuildKit and by the
containerd snapshotter. However, this function differs in behaviour from
the config parser for the RegistryConfig:
- The protocol for insecure registries is treated as significant by
RegistryHosts, while the RegistryConfig strips this information.
- RegistryConfig validates and deduplicates mirrors.
- RegistryConfig does not parse the insecure-registries as URLs, which
can lead to parsing opaque URLs as was possible by the RegistryHosts
function.
This patch updates the lookup function to ensure consistency.

The driver-configurations are only set when creating a new controller,
using the `config.OptionDriverConfig()` option that can be passed to
`New()`, and used as "read-only" after that.
Taking away any other paths that set these options, the only type used
for per-driver options are a `map[string]interface{}`, so we can change
the type from `map[string]interface{}` to a `map[string]map[string]interface{}`,
(or its "modern" variant: `map[string]map[string]any`), so that it's
no longer needed to cast the type before use.

This patch contains some optimizations I still had stashed when working
on eaa9494b71.
- Use the bytes package for handling the output of "lsof", instead of
converting to a string.
- Count the number of newlines in the output, instead of splitting the
output into a slice of strings. We're only interested in the number
of lines in the output.
- Use lsof's -F option to only print the file-descriptor for each line,
as we don't need other information.
- Use the -l, -n, and -P options to omit converting usernames, host names,
and port numbers.
From the [LSOF(8)][1] man-page:
-l This option inhibits the conversion of user ID numbers to
login names. It is also useful when login name lookup is
working improperly or slowly.
-n This option inhibits the conversion of network numbers to host
names for network files. Inhibiting conversion can make lsof run faster.
It is also useful when host name lookup is not working properly.
-P This option inhibits the conversion of port numbers to port names for network files.
Inhibiting the conversion can make lsof run a little faster.
It is also useful when host name lookup is not working properly.
Output looks something like;
lsof -lnP -Ff -p 39849

The `store.Watch()` was only used in `Controller.processEndpointCreate()`,
and skipped if the store was not "watchable" (`store.Watchable()`).
Whether a store is watchable depends on the store's datastore.scope;
local stores are not watchable;
func (ds *datastore) Watchable() bool {
return ds.scope != LocalScope
}
datastore is only initialized in two locations, and both locations set the
scope field to LocalScope:
datastore.newClient() (also called by datastore.NewDataStore()):
3e4c9d90cf/libnetwork/datastore/datastore.go (L213)
datastore.NewTestDataStore() (used in tests);
3e4c9d90cf/libnetwork/datastore/datastore_test.go (L14-L17)
Furthermore, the backing BoltDB kvstore does not implement the Watch()
method;
3e4c9d90cf/libnetwork/internal/kvstore/boltdb/boltdb.go (L464-L467)

- our datastore is never Watchable()
- so datastore.Watch() is never used

The Dockerfile in this repository performs many stages in parallel. If any of
those stages fails to build (which could be due to networking congestion),
other stages are also (forcibly?) terminated, which can cause an unclean
shutdown.
In some case, this can cause `git` to be terminated, leaving a `.lock` file
behind in the cache mount. Retrying the build now will fail, and the only
workaround is to clean the build-cache (which causes many stages to be
built again, potentially triggering the problem again).

This patch:
- Updates the Dockerfile to remove `.lock` files (`shallow.lock`, `index.lock`)
that may have been left behind from previous builds. I put this code in the
Dockerfile itself (not the script), as the script may be used in other
situations outside of the Dockerfile (for which we cannot guarantee no other
git session is active).
- Adds a `docker --version` step to the stage; this is mostly to verify the
build was successful (and to be consistent with other stages).

Before 4bafaa00aa, if the daemon was
killed while a container was running and the container shim is killed
before the daemon is restarted, such as if the host system is
hard-rebooted, the daemon would restore the container to the stopped

If an exec fails to start in such a way that containerd publishes an
exit event for it, daemon.ProcessEvent will race
daemon.ContainerExecStart in handling the failure. This race has been a
long-standing bug, which was mostly harmless until
4bafaa00aa. After that change, the daemon
would dereference a nil pointer and crash if ProcessEvent won the race.
Restore the status quo buggy behaviour by adding a check to skip the

go1.20.5 (released 2023-06-06) includes four security fixes to the cmd/go and
runtime packages, as well as bug fixes to the compiler, the go command, the
runtime, and the crypto/rsa, net, and os packages. See the Go 1.20.5 milestone
on our issue tracker for details:
https://github.com/golang/go/issues?q=milestone%3AGo1.20.5+label%3ACherryPickApproved
full diff: https://github.com/golang/go/compare/go1.20.4...go1.20.5
These minor releases include 3 security fixes following the security policy:
- cmd/go: cgo code injection
The go command may generate unexpected code at build time when using cgo. This
may result in unexpected behavior when running a go program which uses cgo.
This may occur when running an untrusted module which contains directories with
newline characters in their names. Modules which are retrieved using the go command,
i.e. via "go get", are not affected (modules retrieved using GOPATH-mode, i.e.
GO111MODULE=off, may be affected).
Thanks to Juho Nurminen of Mattermost for reporting this issue.
This is CVE-2023-29402 and Go issue https://go.dev/issue/60167.
- runtime: unexpected behavior of setuid/setgid binaries
The Go runtime didn't act any differently when a binary had the setuid/setgid
bit set. On Unix platforms, if a setuid/setgid binary was executed with standard
I/O file descriptors closed, opening any files could result in unexpected
content being read/written with elevated prilieges. Similarly if a setuid/setgid
program was terminated, either via panic or signal, it could leak the contents
of its registers.
Thanks to Vincent Dehors from Synacktiv for reporting this issue.
This is CVE-2023-29403 and Go issue https://go.dev/issue/60272.
- cmd/go: improper sanitization of LDFLAGS
The go command may execute arbitrary code at build time when using cgo. This may
occur when running "go get" on a malicious module, or when running any other
command which builds untrusted code. This is can by triggered by linker flags,
specified via a "#cgo LDFLAGS" directive.

Some snapshotters (like overlayfs or zfs) can't mount the same
directories twice. For example if the same directroy is used as an upper
directory in two mounts the kernel will output this warning:
overlayfs: upperdir is in-use as upperdir/workdir of another mount, accessing files from both mounts will result in undefined behavior.
And indeed accessing the files from both mounts will result in an "No
such file or directory" error.
This change introduces reference counts for the mounts, if a directory
is already mounted the mount interface will only increment the mount
counter and return the mount target effectively making sure that the
filesystem doesn't end up in an undefined behavior.

Many of the fields in LinuxResources struct are pointers to scalars for
some reason, presumably to differentiate between set-to-zero and unset
when unmarshaling from JSON, despite zero being outside the acceptable
range for the corresponding kernel tunables. When creating the OCI spec
for a container, the daemon sets the container's OCI spec CPUShares and
BlkioWeight parameters to zero when the corresponding Docker container
configuration values are zero, signifying unset, despite the minimum
acceptable value for CPUShares being two, and BlkioWeight ten. This has
gone unnoticed as runC does not distingiush set-to-zero from unset as it
also uses zero internally to represent unset for those fields. However,
kata-containers v3.2.0-alpha.3 tries to apply the explicit-zero resource
parameters to the container, exactly as instructed, and fails loudly.
The OCI runtime-spec is silent on how the runtime should handle the case
when those parameters are explicitly set to out-of-range values and
kata's behaviour is not unreasonable, so the daemon must therefore be in
the wrong.
Translate unset values in the Docker container's resources HostConfig to
omit the corresponding fields in the container's OCI spec when starting
and updating a container in order to maximize compatibility with
runtimes.

The daemon has made a habit of mutating the DefaultRuntime and Runtimes
values in the Config struct to merge defaults. This would be fine if it
was a part of the regular configuration loading and merging process,
as is done with other config options. The trouble is it does so in
surprising places, such as in functions with 'verify' or 'validate' in
their name. It has been necessary in order to validate that the user has
not defined a custom runtime named "runc" which would shadow the
built-in runtime of the same name. Other daemon code depends on the
runtime named "runc" always being defined in the config, but merging it
with the user config at the same time as the other defaults are merged
would trip the validation. The root of the issue is that the daemon has
used the same config values for both validating the daemon runtime
configuration as supplied by the user and for keeping track of which
runtimes have been set up by the daemon. Now that a completely separate
value is used for the latter purpose, surprising contortions are no
longer required to make the validation work as intended.
Consolidate the validation of the runtimes config and merging of the
built-in runtimes into the daemon.setupRuntimes() function. Set the
result of merging the built-in runtimes config and default default
runtime on the returned runtimes struct, without back-propagating it
onto the config.Config argument.

The existing runtimes reload logic went to great lengths to replace the
directory containing runtime wrapper scripts as atomically as possible
within the limitations of the Linux filesystem ABI. Trouble is,
atomically swapping the wrapper scripts directory solves the wrong
problem! The runtime configuration is "locked in" when a container is
started, including the path to the runC binary. If a container is
started with a runtime which requires a daemon-managed wrapper script
and then the daemon is reloaded with a config which no longer requires
the wrapper script (i.e. some args -> no args, or the runtime is dropped
from the config), that container would become unmanageable. Any attempts
to stop, exec or otherwise perform lifecycle management operations on
the container are likely to fail due to the wrapper script no longer
existing at its original path.
Atomically swapping the wrapper scripts is also incompatible with the
read-copy-update paradigm for reloading configuration. A handler in the
daemon could retain a reference to the pre-reload configuration for an
indeterminate amount of time after the daemon configuration has been
reloaded and updated. It is possible for the daemon to attempt to start
a container using a deleted wrapper script if a request to run a
container races a reload.
Solve the problem of deleting referenced wrapper scripts by ensuring
that all wrapper scripts are *immutable* for the lifetime of the daemon
process. Any given runtime wrapper script must always exist with the
same contents, no matter how many times the daemon config is reloaded,
or what changes are made to the config. This is accomplished by using
everyone's favourite design pattern: content-addressable storage. Each
wrapper script file name is suffixed with the SHA-256 digest of its
contents to (probabilistically) guarantee immutability without needing
any concurrency control. Stale runtime wrapper scripts are only cleaned
up on the next daemon restart.
Split the derived runtimes configuration from the user-supplied
configuration to have a place to store derived state without mutating
the user-supplied configuration or exposing daemon internals in API
struct types. Hold the derived state and the user-supplied configuration
in a single struct value so that they can be updated as an atomic unit.

Ensure data-race-free access to the daemon configuration without
locking by mutating a deep copy of the config and atomically storing
a pointer to the copy into the daemon-wide configStore value. Any
operations which need to read from the daemon config must capture the
configStore value only once and pass it around to guarantee a consistent
view of the config.
Signed-off-by: Cory Snider <csnider@mirantis.com>
Config reloading has interleaved validations and other fallible
operations with mutating the live daemon configuration. The daemon
configuration could be left in a partially-reloaded state if any of the
operations returns an error. Mutating a copy of the configuration and
atomically swapping the config struct on success is not currently an
option as config values are not copyable due to the presence of
sync.Mutex fields. Introduce a two-phase commit protocol to defer any
mutations of the daemon state until after all fallible operations have
succeeded.
Reload transactions are not yet entirely hermetic. The platform
reloading logic for custom runtimes on *nix could still leave the
directory of generated runtime wrapper scripts in an indeterminate state
if an error is encountered.

Historically, daemon.RegistryHosts() has returned a docker.RegistryHosts
callback function which closes over a point-in-time snapshot of the
daemon configuration. When constructing the BuildKit builder at daemon
startup, the return value of daemon.RegistryHosts() has been used.
Therefore the BuildKit builder would use the registry configuration as
it was at daemon startup for the life of the process, even if the
registry configuration is changed and the configuration reloaded.
Provide BuildKit with a RegistryHosts callback which reflects the
live daemon configuration after reloads so that registry operations
performed by BuildKit always use the same configuration as the rest of
the daemon.

Passing around a bare pointer to the map of configured features in order
to propagate to consumers changes to the configuration across reloads is
dangerous. Map operations are not atomic, so concurrently reading from
the map while it is being updated is a data race as there is no
synchronization. Use a getter function to retrieve the current features
map so the features can be retrieved race-free.
Remove the unused features argument from the build router.

This isn't convenient when a specific manifest is already known and it's
redundant to search the whole index for a manifest that matches the
given platform matcher. It can also result in a different manifest
picked up than expected when multiple manifests with the same platform
are present.
This introduces a walkImageManifests which walks the provided image and
calls a handler with a ImageManifest, which is a simple wrapper that
implements containerd.Image interfaces and performs all containerd.Image
operations against a platform specific manifest instead of the root
manifest list/index.

Resolver.setupIPTable() checks whether it needs to flush or create the
user chains used for NATing container DNS requests by testing for the
existence of the rules which jump to said user chains. Unfortunately it
does so using the IPTable.RawCombinedOutputNative() method, which
returns a non-nil error if the iptables command returns any output even
if the command exits with a zero status code. While that is fine with
iptables-legacy as it prints no output if the rule exists, iptables-nft
v1.8.7 prints some information about the rule. Consequently,
Resolver.setupIPTable() would incorrectly think that the rule does not
exist during container restore and attempt to create it. This happened
work work by coincidence before 8f5a9a741b
because the failure to create the already-existing table would be
ignored and the new NAT rules would be inserted before the stale rules
left in the table from when the container was last started/restored. Now
that failing to create the table is treated as a fatal error, the
incompatibility with iptables-nft is no longer hidden.
Switch to using IPTable.ExistsNative() to test for the existence of the
jump rules as it correctly only checks the iptables command's exit
status without regard for whether it outputs anything.

The method to restore a network namespace takes a collection of
interfaces to restore with the options to apply. The interface names are
structured data, tuples of (SrcName, DstPrefix) but for whatever reason
are being passed into Restore() serialized to strings. A refactor,
f0be4d126d, accidentally broke the
serialization by dropping the delimiter. Rather than fix the
serialization and leave the time-bomb for someone else to trip over,
pass the interface names as structured data.

In cases where an exec start failed the exec process will be nil even
though the channel to signal that the exec started was closed.
Ideally ExecConfig would get a nice refactor to handle this case better
(ie. it's not started so don't close that channel).
This is a minimal fix to prevent NPE. Luckilly this would only get
called by a client and only the http request goroutine gets the panic
(http lib recovers the panic).

While the VXLAN interface and the iptables rules to mark outgoing VXLAN
packets for encryption are configured to use the Swarm data path port,
the XFRM policies for actually applying the encryption are hardcoded to
match packets with destination port 4789/udp. Consequently, encrypted
overlay networks do not pass traffic when the Swarm is configured with
any other data path port: encryption is not applied to the outgoing
VXLAN packets and the destination host drops the received cleartext
packets. Use the configured data path port instead of hardcoding port
4789 in the XFRM policies.

Feature flags are one of the configuration items which can be reloaded
without restarting the daemon. Whether the daemon uses the containerd
snapshotter service or the legacy graph drivers is controlled by a
feature flag. However, much of the code which checks the snapshotter
feature flag assumes that the flag cannot change at runtime. Make it so
that the snapshotter setting can only be changed by restarting the
daemon, even if the flag state changes after a live configuration
reload.

Starting with go1.19, the Go runtime on Windows now supports the `netgo` build-
flag to use a native Go DNS resolver. Prior to that version, the build-flag
only had an effect on non-Windows platforms. When using the `netgo` build-flag,
the Windows's host resolver is not used, and as a result, custom entries in
`etc/hosts` are ignored, which is a change in behavior from binaries compiled
with older versions of the Go runtime.
From the go1.19 release notes: https://go.dev/doc/go1.19#net
> Resolver.PreferGo is now implemented on Windows and Plan 9. It previously
> only worked on Unix platforms. Combined with Dialer.Resolver and Resolver.Dial,
> it's now possible to write portable programs and be in control of all DNS name
> lookups when dialing.
>
> The net package now has initial support for the netgo build tag on Windows.
> When used, the package uses the Go DNS client (as used by Resolver.PreferGo)
> instead of asking Windows for DNS results. The upstream DNS server it discovers
> from Windows may not yet be correct with complex system network configurations,
> however.
Our Windows binaries are compiled with the "static" (`make/binary-daemon`)
script, which has the `netgo` option set by default. This patch unsets the
`netgo` option when cross-compiling for Windows.

This moves the blobs around so they follow the OCI spec.
Note that because docker reads paths from the manifest.json inside the
tar this is not a breaking change.
This does, however, remove the old layer "VERSION" file which had a big

matter at all even for really old versions of Docker. In any case it is
a useless file for any even relatively modern version of Docker.

TestProxyNXDOMAIN has proven to be susceptible to failing as a

osl.setIPv6 mistakenly captured the calling goroutine's thread's network
namespace instead of the network namespace of the thread getting its
namespace temporarily changed. As this function appears to only be
called from contexts in the process's initial network namespace, this
mistake would be of little consequence at runtime. The libnetwork unit
tests, on the other hand, unshare network namespaces so as not to
interfere with each other or the host's network namespace. But due to
this bug, the isolation backfires and the network namespace of
goroutines used by a test which are expected to be in the initial
network namespace can randomly become the isolated network namespace of
some other test. Symptoms include a loopback network server running in
one goroutine being inexplicably and randomly being unreachable by a
client in another goroutine.
Capture the original network namespace of the thread from the thread to
be tampered with, after locking the goroutine to the thread.

tstwriter mocks the server-side connection between the resolver and the
container, not the resolver and the external DNS server, so returning
the external DNS server's address as w.LocalAddr() is technically
incorrect and misleading. Only the protocols need to match as the
resolver uses the client's choice of protocol to determine which
protocol to use when forwarding the query to the external DNS server.

tests slightly more comprehensible for the next person.

This fixes a bug where, if a user pulls an image with a tag != `latest` and
a specific platform, we return an NotFound error for the wrong (`latest`) tag.
see: https://github.com/moby/moby/issues/45558
This bug was introduced in 779a5b3029
in the changes to `daemon/images/image_pull.go`, when we started returning the error from the call to
`GetImage` after the pull. We do this call, if pulling with a specified platform, to check if the platform
of the pulled image matches the requested platform (for cases with single-arch images).
However, when we call `GetImage` we're not passing the image tag, only name, so `GetImage` assumes `latest`
which breaks when the user has requested a different tag, since there might not be such an image in the store.

The internal Client request methods which accept an object as a body use
nil to signal that the request should not have a body. But it is easy to
accidentally pass a typed-nil value as the object, e.g. if the object
comes from a function argument or struct field of a concrete type. The
result is that these requests will, surprisingly, have a JSON body of
`null`. Treat typed-nil pointers the same as untyped nils for the
purposes of determining whether or not the request should include a
body.
Stop assuming that POST requests should always have a body. POST /commit
does not require a body, for example.

Now that most uses of reexec have been replaced with non-reexec
solutions, most of the reexec.Init() calls peppered throughout the test
suites are unnecessary. Furthermore, most of the reexec.Init() calls in
test code neglects to check the return value to determine whether to
exit, which would result in the reexec'ed subprocesses proceeding to run
the tests, which would reexec another subprocess which would proceed to
run the tests, recursively. (That would explain why every reexec
callback used to unconditionally call os.Exit() instead of returning...)
Remove unneeded reexec.Init() calls from test and example code which no
longer needs it, and fix the reexec.Init() calls which are not inert to

Ports over all the previous image delete logic, such as:
- Introduce `prune` and `force` flags
- Introduce the concept of hard and soft image delete conflics, which represent:
- image referenced in multiple tags (soft conflict)
- image being used by a stopped container (soft conflict)
- image being used by a running container (hard conflict)
- Implement delete logic such as:
- if deleting by reference, and there are other references to the same image, just
delete the passed reference
- if deleting by reference, and there is only 1 reference and the image is being used
by a running container, throw an error if !force, or delete the reference and create
a dangling reference otherwise
- if deleting by imageID, and force is true, remove all tags (otherwise soft conflict)
- if imageID, check if stopped container is using the image (soft conflict), and
delete anyway if force
- if imageID was passed in, check if running container is using the image (hard conflict)
- if `prune` is true, and the image being deleted has dangling parents, remove them
This commit also implements logic to get image parents in c8d by comparing shared layers.

term: remove interrupt handler on termios
On termios platforms, interrupt signals are not generated in raw mode
terminals as the ISIG setting is not enabled. Remove interrupt handler
as it does nothing for raw mode and prevents other uses of INT signal
with this library.
This code seems to go back all the way to moby/moby#214 where signal
handling was improved for monolithic docker repository. Raw mode -ISIG
got reintroduced in moby/moby@3f63b87807, but the INT handler was left
behind.

Split the function into a "backing" function that returns an error, and the
re-exec entrypoint, which handles the error to provide a more idiomatic approach.
This was part of a larger change accross multiple re-exec functions (now removed).
For history's sake; here's the description for that;
The `reexec.Register()` function accepts reexec entrypoints, which are a `func()`
without return (matching a binary's `main()` function). As these functions cannot
return an error, it's the entrypoint's responsibility to handle any error, and to
indicate failures through `os.Exit()`.
I noticed that some of these entrypoint functions had `defer()` statements, but
called `os.Exit()` either explicitly or implicitly (e.g. through `logrus.Fatal()`).
defer statements are not executed if `os.Exit()` is called, which rendered these
statements useless.
While I doubt these were problematic (I expect files to be closed when the process
exists, and `runtime.LockOSThread()` to not have side-effects after exit), it also
didn't seem to "hurt" to call these as was expected by the function.
This patch rewrites some of the entrypoints to split them into a "backing function"
that can return an error (being slightly more iodiomatic Go) and an wrapper function
to act as entrypoint (which can handle the error and exit the executable).
To some extend, I'm wondering if we should change the signatures of the entrypoints
to return an error so that `reexec.Init()` can handle (or return) the errors, so
that logging can be handled more consistently (currently, some some use logrus,
some just print); this would also keep logging out of some packages, as well as
allows us to provide more metadata about the error (which reexec produced the
error for example).
A quick search showed that there's some external consumers of pkg/reexec, so I
kept this for a future discussion / exercise.

This is the seventh patch release in the 1.1.z release of runc, and is
the last planned release of the 1.1.z series. It contains a fix for
cgroup device rules with systemd when handling device rules for devices
that don't exist (though for devices whose drivers don't correctly
register themselves in the kernel -- such as the NVIDIA devices -- the
full fix only works with systemd v240+).
- When used with systemd v240+, systemd cgroup drivers no longer skip
DeviceAllow rules if the device does not exist (a regression introduced
in runc 1.1.3). This fix also reverts the workaround added in runc 1.1.5,
removing an extra warning emitted by runc run/start.
- The source code now has a new file, runc.keyring, which contains the keys
used to sign runc releases.

The code seemed overly complicated, requiring a reader to be constructed,
where in all cases, the data was already available in a variable. This patch
simplifies the utility to not require a reader, which also makes it a bit
more performant:

GO111MODULE=off go test -run='^$' -bench=. -count=20 > old.txt
GO111MODULE=off go test -run='^$' -bench=. -count=20 > new.txt

HashData-10 6.00 ± 0% 3.00 ± 0% -50.00% (p=0.000 n=20+20)
A small change was made in `Build()`, which previously returned the resolv.conf
data, even if the function failed to write it. In the new variation, `nil` is
consistently returned on failures.
Note that in various places, the hash is not even used, so we may be able to
simplify things more after this.

http.Server also improves upon server.Server by additionally providing a

Unconditionally checking for RT_GROUP_SCHED is harmful. It is one of
the options that you want inactive unless you know that you want it
active.
Systemd recommends to disable it [1], a rationale for doing so is
provided in
https://bugzilla.redhat.com/show_bug.cgi?id=1229700#c0.
The essence is that you can not simply enable RT_GROUP_SCHED, you also
have to assign budgets manually. If you do not assign budgets, then
your realtime scheduling will be affected.
If check-config.sh keeps recommending to enable this, without further
advice, then users will follow the recommendation and likely run into
issues.
Again, this is one of the options that you want inactive, unless you
know that you want to use it.

The (*network).ipamRelease function nils out the network's IPAM info
fields, putting the network struct into an inconsistent state. The
network-restore startup code panics if it tries to restore a network
from a struct which has fewer IPAM config entries than IPAM info
entries. Therefore (*network).delete contains a critical section: by
persisting the network to the store after ipamRelease(), the datastore
will contain an inconsistent network until the deletion operation
completes and finishes deleting the network from the datastore. If for
any reason the deletion operation is interrupted between ipamRelease()
and deleteFromStore(), the daemon will crash on startup when it tries to
restore the network.
Updating the datastore after releasing the network's IPAM pools may have
served a purpose in the past, when a global datastore was used for
intra-cluster communication and the IPAM allocator had persistent global
state, but nowadays there is no global datastore and the IPAM allocator
has no persistent state whatsoever. Remove the vestigial datastore
update as it is no longer necessary and only serves to cause problems.
If the network deletion is interrupted before the network is deleted
from the datastore, the deletion will resume during the next daemon
startup, including releasing the IPAM pools.

This const looks to only be there for "convenience", or _possibly_ was created
with future normalization or special handling in mind.
In either case, currently it is just a direct copy (alias) for runtime.GOOS,
and defining our own type for this gives the impression that it's more than
that. It's only used in a single place, and there's no external consumers, so
let's deprecate this const, and use runtime.GOOS instead.

Linux kernel prior to v3.16 was not supporting netns for vxlan
interfaces. As such, moby/libnetwork#821 introduced a "host mode" to the
overlay driver. The related kernel fix is available for rhel7 users
since v7.2.
This mode could be forced through the use of the env var
_OVERLAY_HOST_MODE. However this env var has never been documented and
is not referenced in any blog post, so there's little chance many people
rely on it. Moreover, this host mode is deemed as an implementation

remove it without a prior deprecation warning.

Encrypted overlay networks are unique in that they are the only kind of
network for which libnetwork programs an iptables rule to explicitly
accept incoming packets. No other network driver does this. The overlay
driver doesn't even do this for unencrypted networks!
Because the ACCEPT rule is appended to the end of INPUT table rather
than inserted at the front, the rule can be entirely inert on many
common configurations. For example, FirewallD programs an unconditional
REJECT rule at the end of the INPUT table, so any ACCEPT rules appended
after it have no effect. And on systems where the rule is effective, its
presence may subvert the administrator's intentions. In particular,
automatically appending the ACCEPT rule could allow incoming traffic
which the administrator was expecting to be dropped implicitly with a
default-DROP policy.
Let the administrator always have the final say in how incoming
encrypted overlay packets are filtered by no longer automatically
programming INPUT ACCEPT iptables rules for them.

go1.20.3 (released 2023-04-04) includes security fixes to the go/parser,
html/template, mime/multipart, net/http, and net/textproto packages, as well
as bug fixes to the compiler, the linker, the runtime, and the time package.
See the Go 1.20.3 milestone on our issue tracker for details:
https://github.com/golang/go/issues?q=milestone%3AGo1.20.3+label%3ACherryPickApproved
full diff: https://github.com/golang/go/compare/go1.20.2...go1.20.3
Further details from the announcement on the mailing list:
We have just released Go versions 1.20.3 and 1.19.8, minor point releases.
These minor releases include 4 security fixes following the security policy:
- go/parser: infinite loop in parsing
Calling any of the Parse functions on Go source code which contains `//line`
directives with very large line numbers can cause an infinite loop due to
integer overflow.
Thanks to Philippe Antoine (Catena cyber) for reporting this issue.
This is CVE-2023-24537 and Go issue https://go.dev/issue/59180.
- html/template: backticks not treated as string delimiters
Templates did not properly consider backticks (`) as Javascript string
delimiters, and as such did not escape them as expected. Backticks are
used, since ES6, for JS template literals. If a template contained a Go
template action within a Javascript template literal, the contents of the
action could be used to terminate the literal, injecting arbitrary Javascript
code into the Go template.
As ES6 template literals are rather complex, and themselves can do string
interpolation, we've decided to simply disallow Go template actions from being
used inside of them (e.g. "var a = {{.}}"), since there is no obviously safe
way to allow this behavior. This takes the same approach as
github.com/google/safehtml. Template.Parse will now return an Error when it
encounters templates like this, with a currently unexported ErrorCode with a
value of 12. This ErrorCode will be exported in the next major release.
Users who rely on this behavior can re-enable it using the GODEBUG flag
jstmpllitinterp=1, with the caveat that backticks will now be escaped. This
should be used with caution.
Thanks to Sohom Datta, Manipal Institute of Technology, for reporting this issue.
This is CVE-2023-24538 and Go issue https://go.dev/issue/59234.
- net/http, net/textproto: denial of service from excessive memory allocation
HTTP and MIME header parsing could allocate large amounts of memory, even when
parsing small inputs.
Certain unusual patterns of input data could cause the common function used to
parse HTTP and MIME headers to allocate substantially more memory than
required to hold the parsed headers. An attacker can exploit this behavior to
cause an HTTP server to allocate large amounts of memory from a small request,
potentially leading to memory exhaustion and a denial of service.
Header parsing now correctly allocates only the memory required to hold parsed
headers.
Thanks to Jakob Ackermann (@das7pad) for discovering this issue.
This is CVE-2023-24534 and Go issue https://go.dev/issue/58975.
- net/http, net/textproto, mime/multipart: denial of service from excessive resource consumption
Multipart form parsing can consume large amounts of CPU and memory when
processing form inputs containing very large numbers of parts. This stems from
several causes:
mime/multipart.Reader.ReadForm limits the total memory a parsed multipart form
can consume. ReadForm could undercount the amount of memory consumed, leading
it to accept larger inputs than intended. Limiting total memory does not
account for increased pressure on the garbage collector from large numbers of
small allocations in forms with many parts. ReadForm could allocate a large
number of short-lived buffers, further increasing pressure on the garbage
collector. The combination of these factors can permit an attacker to cause an
program that parses multipart forms to consume large amounts of CPU and
memory, potentially resulting in a denial of service. This affects programs
that use mime/multipart.Reader.ReadForm, as well as form parsing in the
net/http package with the Request methods FormFile, FormValue,
ParseMultipartForm, and PostFormValue.
ReadForm now does a better job of estimating the memory consumption of parsed
forms, and performs many fewer short-lived allocations.
In addition, mime/multipart.Reader now imposes the following limits on the
size of parsed forms:
Forms parsed with ReadForm may contain no more than 1000 parts. This limit may
be adjusted with the environment variable GODEBUG=multipartmaxparts=. Form
parts parsed with NextPart and NextRawPart may contain no more than 10,000
header fields. In addition, forms parsed with ReadForm may contain no more
than 10,000 header fields across all parts. This limit may be adjusted with
the environment variable GODEBUG=multipartmaxheaders=.
Thanks to Jakob Ackermann for discovering this issue.

While we currently do not provide an option to specify the snapshotter to use
for individual containers (we may want to add this option in future), currently
it already is possible to configure the snapshotter in the daemon configuration,
which could (likely) cause issues when changing and restarting the daemon.
This patch updates some code-paths that have the container available to use
the snapshotter that's configured for the container (instead of the default
snapshotter configured).
There are still code-paths to be looked into, and a tracking ticket as well as
some TODO's were added for those.

Closing stdin of a container or exec (a.k.a.: task or process) has been
somewhat broken ever since support for ContainerD 1.0 was introduced
back in Docker v17.11: the error returned from the CloseIO() call was
effectively ignored due to it being assigned to a local variable which
shadowed the intended variable. Serendipitously, that oversight
prevented a data race. In my recent refactor of libcontainerd, I
corrected the variable shadowing issue and introduced the aforementioned
data race in the process.
Avoid deadlocking when closing stdin without swallowing errors or
introducing data races by calling CloseIO() synchronously if the process
handle is available, falling back to an asynchronous close-and-log
strategy otherwise. This solution is inelegant and complex, but looks to
be the best that could be done without changing the libcontainerd API.

This implements `docker push` under containerd image store. When
pushing manifest lists that reference a content which is not present in
the local content store, it will attempt to perform the cross-repo mount
the content if possible.
Considering this scenario:
```bash
$ docker pull docker.io/library/busybox
```
This will download manifest list and only host platform-specific
manifest and blobs.
Note, tagging to a different repository (but still the same registry) and pushing:
```bash
$ docker tag docker.io/library/busybox docker.io/private-repo/mybusybox
$ docker push docker.io/private-repo/mybusybox
```
will result in error, because the neither we nor the target repository
doesn't have the manifests that the busybox manifest list references
(because manifests can't be cross-repo mounted).
If for some reason the manifests and configs for all other platforms
would be present in the content store, but only layer blobs were
missing, then the push would work, because the blobs can be cross-repo
mounted (only if we push to the same registry).

The `docker-init` binary is not intended to be a user-facing command, and as such it is more appropriate for it to be found in `/usr/libexec` (or similar) than in `PATH` (see the FHS, especially https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch04s07.html and https://refspecs.linuxfoundation.org/FHS_2.3/fhs-2.3.html#USRLIBLIBRARIESFORPROGRAMMINGANDPA).
This adjusts the logic for using that configuration option to take this into account and appropriately search for `docker-init` (or the user's configured alternative) in these directories before falling back to the existing `PATH` lookup behavior.
This behavior _used_ to exist for the old `dockerinit` binary (of a similar name and used in a similar way but for an alternative purpose), but that behavior was removed in 4357ed4a73 when that older `dockerinit` was also removed.
Most of this reasoning _also_ applies to `docker-proxy` (and various `containerd-xxx` binaries such as the shims), but this change does not affect those. It would be relatively straightforward to adapt `LookupInitPath` to be a more generic function such as `libexecLookupPath` or similar if we wanted to explore that.
See 14482589df/cli-plugins/manager/manager_unix.go for the related path list in the CLI which loads CLI plugins from a similar set of paths (with a similar rationale - plugin binaries are not typically intended to be run directly by users but rather invoked _via_ the CLI binary).

FirewallD creates the root INPUT chain with a default-accept policy and
a terminal rule which rejects all packets not accepted by any prior
rule. Any subsequent rules appended to the chain are therefore inert.
The administrator would have to open the VXLAN UDP port to make overlay
networks work at all, which would result in all VXLAN traffic being
accepted and defeating our attempts to enforce encryption on encrypted
overlay networks.
Insert the rule to drop unencrypted VXLAN packets tagged for encrypted
overlay networks at the top of the INPUT chain so that enforcement of
mandatory encryption takes precedence over any accept rules configured
by the administrator. Continue to append the accept rule to the bottom
of the chain so as not to override any administrator-configured drop
rules.

Some newer distros such as RHEL 9 have stopped making the xt_u32 kernel
module available with the kernels they ship. They do ship the xt_bpf
kernel module, which can do everything xt_u32 can and more. Add an
alternative implementation of the iptables match rule which uses xt_bpf
to implement exactly the same logic as the u32 filter using a BPF
program. Try programming the BPF-powered rules as a fallback when
programming the u32-powered rules fails.

The iptables rule clause used to match on the VNI of VXLAN datagrams
looks like line noise to the uninitiated. It doesn't help that the

The iptables rules which make encryption mandatory on an encrypted
overlay network are only programmed once there is a second node
participating in the network. This leaves single-node encrypted overlay
networks vulnerable to packet injection. Furthermore, failure to program
the rules is not treated as a fatal error.
Program the iptables rules to make encryption mandatory before creating
the VXLAN link to guarantee that there is no window of time where
incoming cleartext VXLAN packets for the network would be accepted, or
outgoing cleartext packets be transmitted. Only create the VXLAN link if
programming the rules succeeds to ensure that it fails closed.

Commit e7d75c8db7 fixed validation of "host"
mode values, but also introduced a regression for validating "container:"
mode PID-modes.
PID-mode implemented a stricter validation than the other options and, unlike
the other options, did not accept an empty container name/ID. This feature was
originally implemented in fb43ef649b, added some
some integration tests (but no coverage for this case), and the related changes
in the API types did not have unit-tests.
While a later change (d4aec5f0a6) added a test
for the `--pid=container:` (empty name) case, that test was later migrated to
the CLI repository, as it covered parsing the flag (and validating the result).

commit 1bd486666b refactored this code, but
it looks like I removed some changes in this part of the code when extracting
these changes from a branch I was working on, and the behavior did not match

This patch:
- fixes containerID() to not return a name/ID if no container: prefix is present
- adds test-coverage for TestCgroupSpec
- adds test-coverage for NetworkMode.ConnectedContainer
- updates some test-tables to remove duplicates, defaults, and use similar cases

Commit 6a516acb2e moved the MemInfo type and
ReadMemInfo() function into the pkg/sysinfo package. In an attempt to assist
consumers of these to migrate to the new location, an alias was added.
Unfortunately, the side effect of this alias is that pkg/system now depends
on pkg/sysinfo, which means that consumers of this (such as docker/cli) now
get all (indirect) dependencies of that package as dependency, which includes
many dependencies that should only be needed for the daemon / runtime;
- github.com/cilium/ebpf
- github.com/containerd/cgroups
- github.com/coreos/go-systemd/v22
- github.com/godbus/dbus/v5

Commit 3246db3755 added handling for removing
cluster volumes, but in some conditions, this resulted in errors not being
returned if the volume was in use;
docker swarm init
docker volume create foo
docker create -v foo:/foo busybox top
docker volume rm foo
This patch changes the logic for ignoring "local" volume errors if swarm
is enabled (and cluster volumes supported).
While working on this fix, I also discovered that Cluster.RemoveVolume()
did not handle the "force" option correctly; while swarm correctly handled
these, the cluster backend performs a lookup of the volume first (to obtain
its ID), which would fail if the volume didn't exist.

SearchRegistryForImages does not make sense as part of the image
service interface. The implementation just wraps the search API of the
registry service to filter the results client-side. It has nothing to do
with local image storage, and the implementation of search does not need
to change when changing which backend (graph driver vs. containerd
snapshotter) is used for local image storage.
Filtering of the search results is an implementation detail: the
consumer of the results does not care which actor does the filtering so
long as the results are filtered as requested. Move filtering into the
exported API of the registry service to hide the implementation details.
Only one thing---the registry service implementation---would need to
change in order to support server-side filtering of search results if
Docker Hub or other registry servers were to add support for it to their
APIs.
Use a fake registry server in the search unit tests to avoid having to
mock out the registry API client.

5008409b5c introduced the usage of
`strings.Cut` to help parse listener addresses.
Part of that also made it error out if no addr is specified after the
protocol spec (e.g. `tcp://`).
Before the change a proto spec without an address just used the default
address for that proto.
e.g. `tcp://` would be `tcp://127.0.0.1:2375`, `unix://` would be
`unix:///var/run/docker.sock`.
Critically, socket activation (`fd://`) never has an address.
This change brings back the old behavior but keeps the usage of
`strings.Cut`.

- Only use the image exporter in build if we don't use containerd
Without this "docker build" fails with:
Error response from daemon: exporter "image" could not be found
- let buildx know we support containerd snapshotter
- Pass the current snapshotter to the buildkit worker
If buildkit uses a different snapshotter we can't list the images any
more because we can't find the snapshot.
builder/builder-next: make ContainerdWorker a minimal wrapper
Note that this makes "Worker" a public field, so technically one could
overwrite it.
builder-next: reenable runc executor
Currently, without special CNI config the builder would
only create host network containers that is a security issue.
Using runc directly instead of shim is faster as well
as builder doesn’t need anything from shim. The overhead
of setting up network sandbox is much slower of course.
builder/builder-next: simplify options handling
Trying to simplify the logic;
- Use an early return if multiple outputs are provided
- Only construct the list of tags if we're using an image (or moby) exporter
- Combine some logic for snapshotter and non-snapshotter handling
Create a constant for the moby exporter
Pass a context when creating a router
The context has a 10 seconds timeout which should be more than enough to
get the answer from containerd.

This addresses the previous issue with the containerd store where, after a container is created, we can't deterministically resolve which image variant was used to run it (since we also don't store what platform the image was fetched for).

When reading through some bug reports, I noticed that the error-message for
unsupported storage drivers is not very informative, as it does not include
the actual storage driver. Some of these errors are used as sentinel errors
internally, so improving the error returned by graphdriver.New() may need
some additional work, but this patch makes a start by including the name
of the graphdriver (if set) in the error-message.
Before this patch:
dockerd --storage-driver=foobar
...
failed to start daemon: error initializing graphdriver: driver not supported
With this patch:
dockerd --storage-driver=foobar
...
failed to start daemon: error initializing graphdriver: driver not supported: foobar
It's worth noting that there may be code "in the wild" that perform string-
matching on this error (e.g. [balena][1]), which is why I included the name as a separate "component"
in the output, to allow matching parts of the error.

It's surprising that the method to begin serving requests is named Wait.
And it is unidiomatic: it is a synchronous call, but it sends its return
value to the channel passed in as an argument instead of just returning
the value. And ultimately it is just a trivial wrapper around serveAPI.
Export the ServeAPI method instead so callers can decide how to call and
synchronize around it.
Call ServeAPI synchronously on the main goroutine in cmd/dockerd. The
goroutine and channel which the Wait() API demanded are superfluous
after all. The notifyReady() call was always concurrent and asynchronous
with respect to serving the API (its implementation spawns a goroutine)
so it makes no difference whether it is called before ServeAPI() or
after `go ServeAPI()`.

The address spaces are orthogonal. There is no shared state between them
logically so there is no reason for them to share any in-memory data
structures. addrSpace is responsible for allocating subnets and
addresses, while Allocator is responsible for implementing the IPAM API.
Lower all the implementation details of allocation into addrSpace.
There is no longer a need to include the name of the address space in
the map keys for subnets now that each addrSpace holds its own state
independently from other addrSpaces. Remove the AddressSpace field from
the struct used for map keys within an addrSpace so that an addrSpace
does not need to know its own name.
Pool allocations were encoded in a tree structure, using parent
references and reference counters. This structure affords for pools
subdivided an arbitrary number of times to be modeled, in theory. In
practice, the max depth is only two: master pools and sub-pools. The
allocator data model has also been heavily influenced by the
requirements and limitations of Datastore persistence, which are no
longer applicable.
Address allocations are always associated with a master pool. Sub-pools
only serve to restrict the range of addresses within the master pool
which could be allocated from. Model pool allocations within an address
space as a two-level hierarchy of maps.

It does NOT indicate that part of the message was lost before reaching

cases by returning ErrTruncated from ReadMsg() if the message was parsed
without error but had the TC flag set. The version of miekg/dns
currently vendored no longer returns an error when a well-formed DNS
message is received which has its TC flag set, but there was some
confusion on how to update libnetwork to deal with this behaviour
change. Truncated DNS replies are no longer different from any other
reply message: they are normal replies which do not need any special-

go1.19.6 (released 2023-02-14) includes security fixes to the crypto/tls,
mime/multipart, net/http, and path/filepath packages, as well as bug fixes to
the go command, the linker, the runtime, and the crypto/x509, net/http, and
time packages. See the Go 1.19.6 milestone on our issue tracker for details:
https://github.com/golang/go/issues?q=milestone%3AGo1.19.6+label%3ACherryPickApproved
From the announcement on the security mailing:
We have just released Go versions 1.20.1 and 1.19.6, minor point releases.
These minor releases include 4 security fixes following the security policy:
- path/filepath: path traversal in filepath.Clean on Windows
On Windows, the filepath.Clean function could transform an invalid path such
as a/../c:/b into the valid path c:\b. This transformation of a relative (if
invalid) path into an absolute path could enable a directory traversal attack.
The filepath.Clean function will now transform this path into the relative
(but still invalid) path .\c:\b.
This is CVE-2022-41722 and Go issue https://go.dev/issue/57274.
- net/http, mime/multipart: denial of service from excessive resource
consumption
Multipart form parsing with mime/multipart.Reader.ReadForm can consume largely
unlimited amounts of memory and disk files. This also affects form parsing in
the net/http package with the Request methods FormFile, FormValue,
ParseMultipartForm, and PostFormValue.
ReadForm takes a maxMemory parameter, and is documented as storing "up to
maxMemory bytes +10MB (reserved for non-file parts) in memory". File parts
which cannot be stored in memory are stored on disk in temporary files. The
unconfigurable 10MB reserved for non-file parts is excessively large and can
potentially open a denial of service vector on its own. However, ReadForm did
not properly account for all memory consumed by a parsed form, such as map
ntry overhead, part names, and MIME headers, permitting a maliciously crafted
form to consume well over 10MB. In addition, ReadForm contained no limit on
the number of disk files created, permitting a relatively small request body
to create a large number of disk temporary files.
ReadForm now properly accounts for various forms of memory overhead, and
should now stay within its documented limit of 10MB + maxMemory bytes of
memory consumption. Users should still be aware that this limit is high and
may still be hazardous.
ReadForm now creates at most one on-disk temporary file, combining multiple
form parts into a single temporary file. The mime/multipart.File interface
type's documentation states, "If stored on disk, the File's underlying
concrete type will be an *os.File.". This is no longer the case when a form
contains more than one file part, due to this coalescing of parts into a
single file. The previous behavior of using distinct files for each form part
may be reenabled with the environment variable
GODEBUG=multipartfiles=distinct.
Users should be aware that multipart.ReadForm and the http.Request methods
that call it do not limit the amount of disk consumed by temporary files.
Callers can limit the size of form data with http.MaxBytesReader.
This is CVE-2022-41725 and Go issue https://go.dev/issue/58006.
- crypto/tls: large handshake records may cause panics
Both clients and servers may send large TLS handshake records which cause
servers and clients, respectively, to panic when attempting to construct

TestRequestReleaseAddressDuplicate gets flagged by go test -race because
the same err variable inside the test is assigned to from multiple
goroutines without synchronization, which obscures whether or not there
are any data races in the code under test.
Trouble is, the test _depends on_ the data race to exit the loop if an
error occurs inside a spawned goroutine. And the test contains a logical
concurrency bug (not flagged by the Go race detector) which can result
in false-positive test failures. Because a release operation is logged
after the IP is released, the other goroutine could reacquire the
address and log that it was reacquired before the release is logged.
Fix up the test so it is no longer subject to data races or
false-positive test failures, i.e. flakes.

If the resolver encounters an error before it attempts to forward the
request to external DNS, do not try to log information about the
external connection, because at this point `extConn` is `nil`. This
makes sure `dockerd` won't panic and crash from a nil pointer

maxDownloadAttempts maps to the daemon configuration flag
--max-download-attempts int
Set the max download attempts for each pull (default 5)
and the daemon configuration machinery interprets a value of 0 as "apply
the default value" and not a valid user value (config validation/
normalization bugs notwithstanding). The intention is clearly that this
configuration value should be an upper limit on the number of times the
daemon should try to download a particular layer before giving up. So it
is surprising to have the configuration value interpreted as a _retry_
limit. The daemon will make up to N+1 attempts to download a layer! This
also means users cannot disable retries even if they wanted to.
Fix the fencepost bug so that max attempts really means max attempts,
not max retries. And fix the fencepost bug with the retry-backoff delay
so that the first backoff is 5s, not 10s.

DNS servers in the loopback address range should always be resolved in
the host network namespace when the servers are configured by reading
from the host's /etc/resolv.conf. The daemon mistakenly conflated the
presence of DNS options (docker run --dns-opt) with user-supplied DNS
servers, treating the list of servers loaded from the host as a user-
supplied list and attempting to resolve in the container's network
namespace. Correct this oversight so that loopback DNS servers are only
resolved in the container's network namespace when the user provides the
DNS server list, irrespective of other DNS configuration.

This makes the `docker save` and `docker load` work with the containerd
image store. The archive is both OCI and Docker compatible.
Saved archive will only contain content which is available locally. In
case the saved image is a multi-platform manifest list, the behavior
depends on the local availability of the content. This is to be
reconsidered when we have the `--platform` option in the CLI.
- If all manifests and their contents, referenced by the manifest list
are present, then the manifest-list is exported directly and the ID
will be the same.
- If only one platform manifest is present, only that manifest is
exported (the image id will change and will be the id of
platform-specific manifest, instead of the full manifest list).
- If multiple, but not all, platform manifests are available, a new
manifest list will be created which will be a subset of the original
manifest list.

The Pid field of an exit event cannot be relied upon to differentiate
exits of the container's task from exits of other container processes,
i.e. execs. The Pid is reported by the runtime and is implementation-
defined so there is no guarantee that a task's pid is distinct from the
pids of any other process in the same container. In particular,
kata-containers reports the pid of the hypervisor for all exit events.
ContainerD guarantees that the process ID of a task is set to the
corresponding container ID, so use that invariant to distinguish task
exits from other process exits.
Signed-off-by: Cory Snider <csnider@mirantis.com>
The ID of the task is known at the time that the FIFOs need to be
created (it's passed into the IO-creator callback, and is also the same

exec'ed processes. Delete the now-unused InitProcessName constant so it
can never again be used in place of a task/process ID.

ContainerD unconditionally sets the ID of a task to its container's ID.

Per the Interface Segregation Principle, network drivers should not have
to depend on GetPluginGetter methods they do not use. The remote network
driver is the only one which needs a PluginGetter, and it is already
special-cased in Controller so there is no sense warping the interfaces
to achieve a foolish consistency. Replace all other network drivers' Init
functions with Register functions which take a driverapi.Registerer
argument instead of a driverapi.DriverCallback. Add back in Init wrapper
functions for only the drivers which Swarmkit references so that
Swarmkit can continue to build.
Refactor the libnetwork Controller to use the new drvregistry.Networks
and drvregistry.IPAMs driver registries in place of the legacy ones.
Signed-off-by: Cory Snider <csnider@mirantis.com>
There is no benefit to having a single registry for both IPAM drivers
and network drivers. IPAM drivers are registered in a separate namespace
from network drivers, have separate registration methods, separate
accessor methods and do not interact with network drivers within a
DrvRegistry in any way. The only point of commonality is
interface { GetPluginGetter() plugingetter.PluginGetter }
which is only used by the respective remote drivers and therefore should
be outside of the scope of a driver registry.
Create new, separate registry types for network drivers and IPAM
drivers, respectively. These types are "legacy-free". Neither type has
GetPluginGetter methods. The IPAMs registry does not have an
IPAMDefaultAddressSpaces method as that information can be queried
directly from the driver using its GetDefaultAddressSpaces method.
The Networks registry does not have an AddDriver method as that method
is a trivial wrapper around calling one of its arguments with its other
arguments.
Refactor DrvRegistry in terms of the new IPAMs and Networks registries
so that existing code in libnetwork and Swarmkit will continue to work.

The datastore arguments to the IPAM driver Init() functions are always
nil, even in Swarmkit. The only IPAM driver which consumed the
datastores was builtin; all others (null, remote, windowsipam) simply
ignored it. As the signatures of the IPAM driver init functions cannot
be changed without breaking the Swarmkit build, they have to be left
with the same signatures for the time being. Assert that nil datastores
are always passed into the builtin IPAM driver's init function so that
there is no ambiguity the datastores are no longer respected.
Add new Register functions for the IPAM drivers which are free from the
legacy baggage of the Init functions. (The legacy Init functions can be
removed once Swarmkit is migrated to using the Register functions.) As
the remote IPAM driver is the only one which depends on a PluginGetter,
pass it in explicitly as an argument to Register. The other IPAM drivers
should not be forced to depend on a GetPluginGetter() method they do not
use (Interface Segregation Principle).

The netutils.ElectInterfaceAddresses function is only used in one place
outside of tests: in the daemon, to configure the default bridge
network. The function is also messy to reason about as it references the
shared mutable state of ipamutils.PredefinedLocalScopeDefaultNetworks.
It uses the list of predefined default networks to always return an IPv4
address even if the named interface does not exist or does not have any
IPv4 addresses. This list happens to be the same as the one used to
initialize the address pool of the 'builtin' IPAM driver, though that is
far from obvious. (Start with "./libnetwork".initIPAMDrivers and trace
the dataflow of the addressPool value. Surprise! Global state is being
mutated using the value of other global mutable state.)
The daemon does not need the fallback behaviour of
ElectInterfaceAddresses. In fact, the daemon does not have to configure
an address pool for the network at all! libnetwork will acquire one of
the available address ranges from the network's IPAM driver when the
preferred-pool configuration is unset. It will do so using the same list
of address ranges and the exact same logic
(netutils.FindAvailableNetworks) as ElectInterfaceAddresses. So unless
the daemon needs to force the network to use a specific address range
because the bridge interface already exists, it can leave the details
up to libnetwork.

type assertion. The mutex is supposed to be a private implementation
detail, but *controller implements sync.Locker because the mutex is
embedded.
c, _ := libnetwork.New()
c.(sync.Locker).Lock()
Change the mutex to an unexported field so *controller no longer
spuriously implements the sync.Locker interface.

When userland-proxy is turned off and on again, the iptables nat rule
doing hairpinning isn't properly removed. This fix makes sure this nat
rule is removed whenever the bridge is torn down or hairpinning is
disabled (through setting userland-proxy to true).
Unlike for ip masquerading and ICC, the `programChainRule()` call
setting up the "MASQ LOCAL HOST" rule has to be called unconditionally
because the hairpin parameter isn't restored from the driver store, but
always comes from the driver config.
For the "SKIP DNAT" rule, things are a bit different: this rule is
always deleted by `removeIPChains()` when the bridge driver is
initialized.
Fixes#44721.

dockerd handles SIGQUIT by dumping all goroutine stacks to standard
error and exiting. In contrast, the Go runtime's default SIGQUIT
behaviour... dumps all goroutine stacks to standard error and exits.
The default SIGQUIT behaviour is implemented directly in the runtime's
signal handler, and so is both more robust to bugs in the Go runtime and
does not perturb the state of the process to anywhere near same degree
as dumping goroutine stacks from a user goroutine. The only notable
difference from a user's perspective is that the process exits with
status 2 instead of 128+SIGQUIT.

By relying on the kernel UAPI (userspace API), we can drop a dependency

btrfs-progs mirrors the kernel headers, but the headers it ships with
are not the canonical source and as [we have seen before][44698], could
be subject to changes.
Depending on the canonical headers from the kernel both is more
idiomatic, and ensures we are protected by the kernel's promise to not

Conntrack entries are created for UDP flows even if there's nowhere to
route these packets (ie. no listening socket and no NAT rules to
apply). Moreover, iptables NAT rules are evaluated by netfilter only
when creating a new conntrack entry.
When Docker adds NAT rules, netfilter will ignore them for any packet
matching a pre-existing conntrack entry. In such case, when
dockerd runs with userland proxy enabled, packets got routed to it and
the main symptom will be bad source IP address (as shown by #44688).
If the publishing container is run through Docker Swarm or in
"standalone" Docker but with no userland proxy, affected packets will
be dropped (eg. routed to nowhere).
As such, Docker needs to flush all conntrack entries for published UDP
ports to make sure NAT rules are correctly applied to all packets.
- Fixes#44688
- Fixes#8795
- Fixes#16720
- Fixes#7540
- Fixesmoby/libnetwork#2423

As a precautionary measure, those conntrack entries are also flushed
when revoking external connectivity to avoid those entries to be reused
when a new sandbox is created (although the kernel should already
prevent such case).

The IPCMode type was added in 497fc8876e, and from
that patch, the intent was to allow `host` (without `:`), `""` (empty, default)

Later on, `PidMode`, and `UTSMode` were added in 23feaaa240

- moved into the libcontainer pkg: 6158ccad97
- moved within the networkdriver pkg: 4cdcea2047

(*Daemon).registerLinks() calling the WriteHostConfig() method of its
container argument is a vestigial behaviour. In the distant past,
registerLinks() would persist the container links in an SQLite database
and drop the link config from the container's persisted HostConfig. This
changed in Docker v1.10 (#16032) which migrated away from SQLite and
began using the link config in the container's HostConfig as the

HostConfig at all so persisting the HostConfig to disk falls outside of

(*Container).CheckpointTo() upserts a snapshot of the container to the
daemon's in-memory ViewDB and also persists the snapshot to disk. It
does not register the live container object with the daemon's container
store, however. The ViewDB and container store are used as the source of
truth for different operations, so having a container registered in one
but not the other can result in inconsistencies. In particular, the List
Containers API uses the ViewDB as its source of truth and the Container
Inspect API uses the container store.
The (*Daemon).setHostConfig() method is called fairly early in the
process of creating a container, long before the container is registered
in the daemon's container store. Due to a rogue CheckpointTo() call
inside setHostConfig(), there is a window of time where a container can
be included in a List Containers API response but "not exist" according
to the Container Inspect API and similar endpoints which operate on a
particular container. Remove the rogue call so that the caller has full
control over when the container is checkpointed and update callers to
checkpoint explicitly. No changes to (*Daemon).create() are needed as it
checkpoints the fully-created container via (*Daemon).Register().

The List Images API endpoint has accepted multiple values for the

created timestamps against. In other words, the behaviour was undefined.
Change these filter predicates to have well-defined semantics: the
logical AND of all values for each of the respective predicates. As
timestamps are a totally-ordered relation, this is exactly equivalent to
applying the newest and oldest creation timestamps for the `since` and

Includes security fixes for net/http (CVE-2022-41717, CVE-2022-41720),
and os (CVE-2022-41720).
These minor releases include 2 security fixes following the security policy:
- os, net/http: avoid escapes from os.DirFS and http.Dir on Windows
The os.DirFS function and http.Dir type provide access to a tree of files
rooted at a given directory. These functions permitted access to Windows
device files under that root. For example, os.DirFS("C:/tmp").Open("COM1")
would open the COM1 device.
Both os.DirFS and http.Dir only provide read-only filesystem access.
In addition, on Windows, an os.DirFS for the directory \(the root of the
current drive) can permit a maliciously crafted path to escape from the
drive and access any path on the system.
The behavior of os.DirFS("") has changed. Previously, an empty root was
treated equivalently to "/", so os.DirFS("").Open("tmp") would open the
path "/tmp". This now returns an error.
This is CVE-2022-41720 and Go issue https://go.dev/issue/56694.
- net/http: limit canonical header cache by bytes, not entries
An attacker can cause excessive memory growth in a Go server accepting
HTTP/2 requests.
HTTP/2 server connections contain a cache of HTTP header keys sent by
the client. While the total number of entries in this cache is capped,
an attacker sending very large keys can cause the server to allocate
approximately 64 MiB per open connection.
This issue is also fixed in golang.org/x/net/http2 vX.Y.Z, for users
manually configuring HTTP/2.
Thanks to Josselin Costanzi for reporting this issue.

Some background from the associated ticket:
> We want to use vsock for guest-host communication on KubeVirt
> (https://github.com/kubevirt/kubevirt). In KubeVirt we run VMs in pods.
>
> However since anyone can just connect from any pod to any VM with the
> default seccomp settings, we cannot limit connection attempts to our
> privileged node-agent.
>
> ### Describe the solution you'd like
> We want to deny the `socket` syscall for the `AF_VSOCK` family by default.
>
> I see in [1] and [2] that AF_VSOCK was actually already blocked for some
> time, but that got reverted since some architectures support the `socketcall`
> syscall which can't be restricted properly. However we are mostly interested
> in `arm64` and `amd64` where limiting `socket` would probably be enough.
>
> ### Additional context
> I know that in theory we could use our own seccomp profiles, but we would want
> to provide security for as many users as possible which use KubeVirt, and there
> it would be very helpful if this protection could be added by being part of the
> DefaultRuntime profile to easily ensure that it is active for all pods [3].
>
> Impact on existing workloads: It is unlikely that this will disturb any existing
> workload, becuase VSOCK is almost exclusively used for host-guest commmunication.
> However if someone would still use it: Privileged pods would still be able to
> use `socket` for `AF_VSOCK`, custom seccomp policies could be applied too.
> Further it was already blocked for quite some time and the blockade got lifted
> due to reasons not related to AF_VSOCK.

This commit allows to remove dependency on the mutable version armon/go-radix.
The go-immutable-radix package is better maintained.
It is likely that a bit more memory will be used when using the
immutable version, though discarded nodes are being reused in a pool.
These changes happen when networks are added/removed or nodes come and
go in a cluster, so we are still talking about a relatively low
frequency event.
The major changes compared to the old radix are when modifying (insert
or delete) a tree, and those are pretty self-contained: we replace the
entire immutable tree under a lock.

TestCreateParallel, which was ostensibly added as a regression test for
race conditions inside the bridge driver, contains a race condition. The
getIPv4Data() calls race the network configuration and so will sometimes
see the existing address assignments return IP address ranges which do
not conflict with them. While normally a good thing, the test asserts
that exactly one of the 100 networks is successfully created. Pass the
same IPAM data when attempting to create every network to ensure that
the address ranges conflict.

addresses() would incorrectly return all IP addresses assigned to any
interface in the network namespace if exists() is false. This went
unnoticed as the unit test covering this case tested the method inside a
clean new network namespace, which had no interfaces brought up and
therefore no IP addresses assigned. Modifying
testutils.SetupTestOSContext() to bring up the loopback interface 'lo'
resulted in the loopback addresses 127.0.0.1 and [::1] being assigned to
the loopback interface, causing addresses() to return the loopback
addresses and TestAddressesEmptyInterface to start failing. Fix the
implementation of addresses() so that it only ever returns addresses for
the bridge interface.

portallocator.PortAllocator holds persistent state on port allocations
in the network namespace. It normal operation it is used as a singleton,
which is a problem in unit tests as every test runs in a clean network
namespace. The singleton "default" PortAllocator remembers all the port
allocations made in other tests---in other network namespaces---and
can result in spurious test failures. Refactor the bridge driver so that
tests can construct driver instances with unique PortAllocators.

The global netlink handle ns.NlHandle() is indirectly cached for the
life of the process by the netutils.CheckRouteOverlaps() function. This
caching behaviour is a problem for the libnetwork unit tests as the
global netlink handle changes every time testutils.SetupTestOSContext()
is called, i.e. at the start of nearly every test case. Route overlaps
can be checked for in the wrong network namespace, causing spurious test
failures e.g. when running the same test twice in a row with -count=2.
Stop the netlink handle from being cached by shadowing the package-scope
variable with a function-scoped one.

TestParallel has been written in an unusual style which relies on the
testing package's intra-test parallelism feature and lots of global
state to test one thing using three cooperating parallel tests. It is
complicated to reason about and quite brittle. For example, the command
go test -run TestParallel1 ./libnetwork
would deadlock, waiting until the test timeout for TestParallel2 and
TestParallel3 to run. And the test would be skipped if the
'-test.parallel' flag was less than three, either explicitly or
implicitly (default: GOMAXPROCS).
Overhaul TestParallel to address the aforementioned deficiencies and
get rid of mutable global state.

Reusing the same "OS context" (read: network namespace) and
NetworkController across multiple tests risks tests interfering with
each other, or worse: _depending on_ other tests to set up
preconditions. Construct a new controller for every test which needs
one, and run every test which mutates or inspects the host environment
in a fresh OS context.
The only outlier is runParallelTests. It is the only remaining test
implementation which references the "global" package-scoped controller,
so the global controller instance is effectively private to that one
test.

The SetupTestOSContext calls were made conditional in
https://github.com/moby/libnetwork/pull/148 to work around limitations
in runtime.LockOSThread() which existed before Go 1.10. This workaround
is no longer necessary now that runtime.UnlockOSThread() needs to be
called an equal number of times before the goroutine is unlocked from
the OS thread.
Unfortunately some tests break when SetupTestOSContext is not skipped.
(Evidently this code path has not been exercised in a long time.) A
newly-created network namespace is very barebones: it contains a
loopback interface in the down state and little else. Even pinging
localhost does not work inside of a brand new namespace. Set the
loopback interface to up during namespace setup so that tests which
need to use the loopback interface can do so.

unix.Kill() does not produce an error for PID 0, -1. As a result, checking

Mounting a container's volumes under its rootfs directory inside the
host mount namespace causes problems with cross-namespace mount
propagation when /var/lib/docker is bind-mounted into the container as a
volume. The mount event propagates into the container's mount namespace,
overmounting the volume, but the propagated unmount events do not fully
reverse the effect. Each archive operation causes the mount table in the
container's mount namespace to grow larger and larger, until the kernel
limiton the number of mounts in a namespace is hit. The only solution to
this issue which is not subject to race conditions or other blocker
caveats is to avoid mounting volumes into the container's rootfs
directory in the host mount namespace in the first place.
Mount the container volumes inside an unshared mount namespace to
prevent any mount events from propagating into any other mount
namespace. Greatly simplify the archiving implementations by also
chrooting into the container rootfs to sidestep the need to resolve
paths in the host.

This change was introduced early in the development of rootless support,
before all the kinks were worked out and rootlesskit was built. The
author was testing the daemon by inside a user namespace set up by runc,
observed that the unshare(2) syscall was returning EPERM, and assumed
that it was a fundamental limitation of user namespaces. Seeing as the
kernel documentation (of today) disagrees with that assessment and that
unshare demonstrably works inside user namespaces, I can only assume
that the EPERM was due to a quirk of their test environment, such as a
seccomp filter set up by runc blocking the unshare syscall.

Aside from unconditionally unlocking the OS thread even if restoring the
thread's network namespace fails, func (*networkNamespace).InvokeFunc()
correctly implements invoking a function inside a network namespace.
This is far from obvious, however. func InitOSContext() does much of the
heavy lifting but in a bizarre fashion: it restores the initial network
namespace before it is changed in the first place, and the cleanup
function it returns does not restore the network namespace at all! The
InvokeFunc() implementation has to restore the network namespace
explicitly by deferring a call to ns.SetNamespace().
func InitOSContext() is a leaky abstraction taped to a footgun. On the
one hand, it defensively resets the current thread's network namespace,
which has the potential to fix up the thread state if other buggy code
had failed to maintain the invariant that an OS thread must be locked to
a goroutine unless it is interchangeable with a "clean" thread as
spawned by the Go runtime. On the other hand, it _facilitates_ writing
buggy code which fails to maintain the aforementioned invariant because
the cleanup function it returns unlocks the thread from the goroutine
unconditionally while neglecting to restore the thread's network
namespace! It is quite scary to need a function which fixes up threads'
network namespaces after the fact as an arbitrary number of goroutines
could have been scheduled onto a "dirty" thread and run non-libnetwork
code before the thread's namespace is fixed up. Any number of
(not-so-)subtle misbehaviours could result if an unfortunate goroutine
is scheduled onto a "dirty" thread. The whole repository has been
audited to ensure that the aforementioned invariant is never violated,
making after-the-fact fixing up of thread network namespaces redundant.
Make InitOSContext() a no-op on Linux and inline the thread-locking into
the function (singular) which previously relied on it to do so.
func ns.SetNamespace() is of similarly dubious utility. It intermixes
capturing the initial network namespace and restoring the thread's
network namespace, which could result in threads getting put into the
wrong network namespace if the wrong thread is the first to call it.
Delete it entirely; functions which need to manipulate a thread's
network namespace are better served by being explicit about capturing
and restoring the thread's namespace.
Rewrite InvokeFunc() to invoke the closure inside a goroutine to enable
a graceful and safe recovery if the thread's network namespace could not
be restored. Avoid any potential race conditions due to changing the
main thread's network namespace by preventing the aforementioned
goroutines from being eligible to be scheduled onto the main thread.

func (*network) watchMiss() correctly locks its goroutine to an OS

avoid the issues which would arise if such a situation was to occur.

The parallel tests were unconditionally unlocking the test case
goroutine from the OS thread, irrespective of whether the thread's
network namespace was successfully restored. This was not a problem in
practice as the unpaired calls to runtime.LockOSThread() peppered

unlocked. Unlock the goroutine from the thread iff the thread's network
namespace is successfully restored.

testutils.SetupTestOSContext() sets the calling thread's network
namespace but neglected to restore it on teardown. This was not a
problem in practice as it called runtime.LockOSThread() twice but
runtime.UnlockOSThread() only once, so the tampered threads would be
terminated by the runtime when the test case returned and replaced with
a clean thread. Correct the utility so it restores the thread's network
namespace during teardown and unlocks the goroutine from the thread on
success.
Remove unnecessary runtime.LockOSThread() calls peppering test cases
which leverage testutils.SetupTestOSContext().

`system.MkdirAll()` is a special version of os.Mkdir to handle creating directories
using Windows volume paths (`"\\?\Volume{4c1b02c1-d990-11dc-99ae-806e6f6e6963}"`).
This may be important when `MkdirAll` is used, which traverses all parent paths to
create them if missing (ultimately landing on the "volume" path).
The daemon.NewDaemon() function used `system.MkdirAll()` in various places where
a subdirectory within `daemon.Root` was created. This appeared to be mostly out
of convenience (to not have to handle `os.ErrExist` errors). The `daemon.Root`
directory should already be set up in these locations, and should be set up with
correct permissions. Using `system.MkdirAll()` would potentially mask errors if
the root directory is missing, and instead set up parent directories (possibly
with incorrect permissions).
Because of the above, this patch changes `system.MkdirAll` to `os.Mkdir`. As we
are changing these lines, this patch also changes the legacy octal notation
(`0700`) to the now preferred `0o700`.
One location continues to use `system.MkdirAll`, as the temp-directory may be
configured to be outside of `daemon.Root`, but a redundant `os.Stat(realTmp)`
was removed, as `system.MkdirAll` is expected to handle this.
As we are changing these lines, this patch also changes the legacy octal notation
(`0700`) to the now preferred `0o700`.

system.MkdirAll is a special version of os.Mkdir to handle creating directories
using Windows volume paths ("\\?\Volume{4c1b02c1-d990-11dc-99ae-806e6f6e6963}").
This may be important when MkdirAll is used, which traverses all parent paths to
create them if missing (ultimately landing on the "volume" path).
Commit 62f648b061 introduced the system.MkdirAll
calls, as a change was made in applyLayer() for Windows to use Windows volume
paths as an alternative for chroot (which is not supported on Windows). Later
iteractions changed this to regular Windows long-paths (`\\?\<path>`) in
230cfc6ed2, and 9b648dfac6.
Such paths are handled by the `os` package.
However, in these tests, the parent path already exists (all paths created are
a direct subdirectory within `tmpDir`). It looks like `MkdirAll` here is used
out of convenience to not have to handle `os.ErrExist` errors. As all these
tests are running in a fresh temporary directory, there should be no need to
handle those, and it's actually desirable to produce an error in that case, as
the directory already existing would be unexpected.
Because of the above, this test changes `system.MkdirAll` to `os.Mkdir`. As we
are changing these lines, this patch also changes the legacy octal notation
(`0700`) to the now preferred `0o700`.

executed dies. The runtime terminates an OS thread when a goroutine
exits after being wired to the thread with runtime.LockOSThread(). If
other goroutines are allowed to be scheduled onto a thread which called

subprocess has exited. No other goroutines can be scheduled onto a
locked thread so it will remain alive until unlocked or the daemon
process exits.

This utility was only used in a single place, and had no external consumers.
Move it to where it's used.

The pkg/fsutils package was forked in containerd, and later moved to
containerd/continuity/fs. As we're moving more bits to containerd, let's also
use the same implementation to reduce code-duplication and to prevent them from
diverging.

This utility was added in 442b45628e as part of
user-namespaces, and first used in 44e1023a93 to
set up the daemon root, and move the existing content;
44e1023a93/daemon/daemon_experimental.go (L68-L71)
A later iteration no longer _moved_ the existing root directory, and removed the
use of `directory.MoveToSubdir()` e8532023f2
It looks like there's no external consumers of this utility, so we should be
save to remove it.

- separate exported function from implementation, to allow for GoDoc to be
maintained in a single location.
- don't use named return variables (no "bare" return, and potentially shadowing
variables)
- reverse the `os.IsNotExist(err) && d != dir` condition, putting the "lighter"
`d != dir` first.

I noticed the comment above this code, but didn't see a corresponding type-cast.
Looking at this file's history, I found that these were removed as part of
2f5f0af3fd, which looks to have overlooked some
deliberate type-casts.

This adds a new filter argument to the volume prune endpoint "all".
When this is not set, or it is a false-y value, then only anonymous
volumes are considered for pruning.
When `all` is set to a truth-y value, you get the old behavior.
This is an API change, but I think one that is what most people would
want.

From the mailing list:
We have just released Go versions 1.19.2 and 1.18.7, minor point releases.
These minor releases include 3 security fixes following the security policy:
- archive/tar: unbounded memory consumption when reading headers
Reader.Read did not set a limit on the maximum size of file headers.
A maliciously crafted archive could cause Read to allocate unbounded
amounts of memory, potentially causing resource exhaustion or panics.
Reader.Read now limits the maximum size of header blocks to 1 MiB.
Thanks to Adam Korczynski (ADA Logics) and OSS-Fuzz for reporting this issue.
This is CVE-2022-2879 and Go issue https://go.dev/issue/54853.
- net/http/httputil: ReverseProxy should not forward unparseable query parameters
Requests forwarded by ReverseProxy included the raw query parameters from the
inbound request, including unparseable parameters rejected by net/http. This
could permit query parameter smuggling when a Go proxy forwards a parameter
with an unparseable value.
ReverseProxy will now sanitize the query parameters in the forwarded query
when the outbound request's Form field is set after the ReverseProxy.Director
function returns, indicating that the proxy has parsed the query parameters.
Proxies which do not parse query parameters continue to forward the original
query parameters unchanged.
Thanks to Gal Goldstein (Security Researcher, Oxeye) and
Daniel Abeles (Head of Research, Oxeye) for reporting this issue.
This is CVE-2022-2880 and Go issue https://go.dev/issue/54663.
- regexp/syntax: limit memory used by parsing regexps
The parsed regexp representation is linear in the size of the input,
but in some cases the constant factor can be as high as 40,000,
making relatively small regexps consume much larger amounts of memory.
Each regexp being parsed is now limited to a 256 MB memory footprint.
Regular expressions whose representation would use more space than that
are now rejected. Normal use of regular expressions is unaffected.

Before this change restarting the daemon in live-restore with running
containers + a restart policy meant that volume refs were not restored.
This specifically happens when the container is still running *and*
there is a restart policy that would make sure the container was running
again on restart.
The bug allows volumes to be removed even though containers are
referencing them. 😱

Managed containerd processes are executed with SysProcAttr.Pdeathsig set
to syscall.SIGKILL so that the managed containerd is automatically
killed along with the daemon. At least, that is the intention. In
practice, the signal is sent to the process when the creating _OS
thread_ dies! If a goroutine exits while locked to an OS thread, the Go
runtime will terminate the thread. If that thread happens to be the
same thread which the subprocess was started from, the subprocess will
be signaled. Prevent the journald driver from sometimes unintentionally
killing child processes by ensuring that all runtime.LockOSThread()
calls are paired with runtime.UnlockOSThread().

The `docker` CLI currently doesn't handle situations where the current context
(as defined in `~/.docker/config.json`) is invalid or doesn't exist. As loading
(and checking) the context happens during initialization of the CLI, this
prevents `docker context` commands from being used, which makes it complicated
to fix the situation. For example, running `docker context use <correct context>`
would fail, which makes it not possible to update the `~/.docker/config.json`,
unless doing so manually.
For example, given the following `~/.docker/config.json`:
```json
{
"currentContext": "nosuchcontext"
}
```
All of the commands below fail:
```bash
docker context inspect rootless
Current context "nosuchcontext" is not found on the file system, please check your config file at /Users/thajeztah/.docker/config.json
docker context rm --force rootless
Current context "nosuchcontext" is not found on the file system, please check your config file at /Users/thajeztah/.docker/config.json
docker context use default
Current context "nosuchcontext" is not found on the file system, please check your config file at /Users/thajeztah/.docker/config.json
```
While these things should be fixed, this patch updates the script to switch
the context using the `--context` flag; this flag is taken into account when
initializing the CLI, so that having an invalid context configured won't
block `docker context` commands from being executed. Given that all `context`
commands are local operations, "any" context can be used (it doesn't need to
make a connection with the daemon).
With this patch, those commands can now be run (and won't fail for the wrong
reason);
```bash
docker --context=default context inspect -f "{{.Name}}" rootless
rootless
docker --context=default context inspect -f "{{.Name}}" rootless-doesnt-exist
context "rootless-doesnt-exist" does not exist
```
One other issue may also cause things to fail during uninstall; trying to remove
a context that doesn't exist will fail (even with the `-f` / `--force` option
set);
```bash
docker --context=default context rm blablabla
Error: context "blablabla": not found
```
While this is "ok" in most circumstances, it also means that (potentially) the
current context is not reset to "default", so this patch adds an explicit
`docker context use`, as well as unsetting the `DOCKER_HOST` and `DOCKER_CONTEXT`
environment variables.

It was only used in a single location, and the ErrExtractPointNotDirectory was
not checked for, or used as a sentinel error.
This error was introduced in c32dde5baa. It was
never used as a sentinel error, but from that commit, it looks like it was added
as a package variable to mirror already existing errors defined at the package

This patch removes the exported variable, and replaces the error with an
errdefs.InvalidParameter(), so that the API also returns the correct (400)

This fixes an inifinite loop in mkdirAs(), used by `MkdirAllAndChown`,
`MkdirAndChown`, and `MkdirAllAndChownNew`, as well as directories being
chown'd multiple times when relative paths are used.
The for loop in this function was incorrectly assuming that;
1. `filepath.Dir()` would always return the parent directory of any given path
2. traversing any given path to ultimately result in "/"
While this is correct for absolute and "cleaned" paths, both assumptions are
incorrect in some variations of "path";
1. for paths with a trailing path-separator ("some/path/"), or dot ("."),
`filepath.Dir()` considers the (implicit) "." to be a location _within_ the
directory, and returns "some/path" as ("parent") directory. This resulted
in the path itself to be included _twice_ in the list of paths to chown.
2. for relative paths ("./some-path", "../some-path"), "traversing" the path
would never end in "/", causing the for loop to run indefinitely:
```go
// walk back to "/" looking for directories which do not exist
// and add them to the paths array for chown after creation
dirPath := path
for {
dirPath = filepath.Dir(dirPath)
if dirPath == "/" {
break
}
if _, err := os.Stat(dirPath); err != nil && os.IsNotExist(err) {
paths = append(paths, dirPath)
}
}
```
A _partial_ mitigation for this would be to use `filepath.Clean()` before using
the path (while `filepath.Dir()` _does_ call `filepath.Clean()`, it only does so
_after_ some processing, so only cleans the result). Doing so would prevent the
double chown from happening, but would not prevent the "final" path to be "."
or ".." (in the relative path case), still causing an infinite loop, or
additional checks for "." / ".." to be needed.
| path | filepath.Dir(path) | filepath.Dir(filepath.Clean(path)) |
|----------------|--------------------|------------------------------------|
| some-path | . | . |
| ./some-path | . | . |
| ../some-path | .. | .. |
| some/path/ | some/path | some |
| ./some/path/ | some/path | some |
| ../some/path/ | ../some/path | ../some |
| some/path/. | some/path | some |
| ./some/path/. | some/path | some |
| ../some/path/. | ../some/path | ../some |
| /some/path/ | /some/path | /some |
| /some/path/. | /some/path | /some |
Instead, this patch adds a `filepath.Abs()` to the function, so make sure that
paths are both cleaned, and not resulting in an infinite loop.

The OCI image spec is considering to change the Image struct and embedding the
Platform type (see opencontainers/image-spec#959) in the go implementation.
Moby currently uses some struct-literals to propagate the platform fields,
which will break once those changes in the OCI spec are merged.
Ideally (once that change arrives) we would update the code to set the Platform
information as a whole, instead of assigning related fields individually, but
in some cases in the code, image platform information is only partially set
(for example, OSVersion and OSFeatures are not preserved in all cases). This
may be on purpose, so needs to be reviewed.
This patch keeps the current behavior (assigning only specific fields), but
removes the use of struct-literals to make the code compatible with the
upcoming changes in the image-spec module.

From the mailing list:
We have just released Go versions 1.19.1 and 1.18.6, minor point releases.
These minor releases include 2 security fixes following the security policy:
- net/http: handle server errors after sending GOAWAY
A closing HTTP/2 server connection could hang forever waiting for a clean
shutdown that was preempted by a subsequent fatal error. This failure mode
could be exploited to cause a denial of service.
Thanks to Bahruz Jabiyev, Tommaso Innocenti, Anthony Gavazzi, Steven Sprecher,

This is CVE-2022-27664 and Go issue https://go.dev/issue/54658.
- net/url: JoinPath does not strip relative path components in all circumstances
JoinPath and URL.JoinPath would not remove `../` path components appended to a
relative path. For example, `JoinPath("https://go.dev", "../go")` returned the
URL `https://go.dev/../go`, despite the JoinPath documentation stating that
`../` path elements are cleaned from the result.

1. Commit 1a22418f9f changed permissions to `0700`
on Windows, or more factually, it removed `rw` (`chmod g-rw,o-rw`) and added
executable bits (`chmod u+x`).
2. This was too restrictive, and b7dc9040f0 changed
permissions to only remove the group- and world-writable bits to give read and
execute access to everyone, but setting execute permissions for everyone.
3. However, this also removed the non-permission bits, so 41eb61d5c2
updated the code to preserve those, and keep parity with Linux.
This changes it back to `2.`. I wonder (_think_) _permission_ bits (read, write)
can be portable, except for the _executable_ bit (which is not present on Windows).
The alternative could be to keep the permission bits, and only set the executable
bit (`perm | 0111`) for everyone (equivalent of `chmod +x`), but that likely would
be a breaking change.

The fillGo18FileTypeBits func was added in 1a451d9a7b
to keep the tar headers consistent with headers created with go1.8 and older.
go1.8 and older incorrectly preserved all file-mode bits, including file-type,
instead of stripping those bits and only preserving the _permission_ bits, as
defined in;
- the GNU tar spec: https://www.gnu.org/software/tar/manual/html_node/Standard.html
- and POSIX: http://pubs.opengroup.org/onlinepubs/009695399/basedefs/tar.h.html
We decided at the time to copy the "wrong" behavior to prevent a cache-bust and
to keep the archives identical, however:
- It's not matching the standards, which causes differences between our tar
implementation and the standard tar implementations, as well as implementations
in other languages, such as Python (see docker/compose#883).
- BuildKit does not implement this hack.
- We don't _need_ this extra information (as it's already preserved in the
type header; https://pkg.go.dev/archive/tar#pkg-constants

We have integration tests which assert the invariant that a
GET /containers/{id}/json response lists only IDs of execs which are in
the Running state, according to GET /exec/{id}/json. The invariant could
be violated if those requests were to race the handling of the exec's
task-exit event. The coarse-grained locking of the container ExecStore
when starting an exec task was accidentally synchronizing
(*Daemon).ProcessEvent and (*Daemon).ContainerExecInspect to it just
enough to make it improbable for the integration tests to catch the
invariant violation on execs which exit immediately. Removing the
unnecessary locking made the underlying race condition more likely for
the tests to hit.
Maintain the invariant by deleting the exec from its container's
ExecCommands before clearing its Running flag. Additionally, fix other
potential data races with execs by ensuring that the ExecConfig lock is
held whenever a mutable field is read from or written to.

The containerd client is very chatty at the best of times. Because the
libcontained API is stateless and references containers and processes by
string ID for every method call, the implementation is essentially
forced to use the containerd client in a way which amplifies the number
of redundant RPCs invoked to perform any operation. The libcontainerd
remote implementation has to reload the containerd container, task
and/or process metadata for nearly every operation. This in turn
amplifies the number of context switches between dockerd and containerd
to perform any container operation or handle a containerd event,
increasing the load on the system which could otherwise be allocated to
workloads.
Overhaul the libcontainerd interface to reduce the impedance mismatch
with the containerd client so that the containerd client can be used
more efficiently. Split the API out into container, task and process
interfaces which the consumer is expected to retain so that
libcontainerd can retain state---especially the analogous containerd
client objects---without having to manage any state-store inside the
libcontainerd client.

The OOMKilled flag on a container's state has historically behaved
rather unintuitively: it is updated on container exit to reflect whether
or not any process within the container has been OOM-killed during the
preceding run of the container. The OOMKilled flag would be set to true
when the container exits if any process within the container---including
execs---was OOM-killed at any time while the container was running,
whether or not the OOM-kill was the cause of the container exiting. The
flag is "sticky," persisting through the next start of the container;
only being cleared once the container exits without any processes having
been OOM-killed that run.
Alter the behavior of the OOMKilled flag such that it signals whether
any process in the container had been OOM-killed since the most recent
start of the container. Set the flag immediately upon any process being
OOM-killed, and clear it when the container transitions to the "running"
state.
There is an ulterior motive for this change. It reduces the amount of
state the libcontainerd client needs to keep track of and clean up on
container exit. It's one less place the client could leak memory if a
container was to be deleted without going through libcontainerd.

The daemon.containerd.Exec call does not access or mutate the
container's ExecCommands store in any way, and locking the exec config
is sufficient to synchronize with the event-processing loop. Locking
the ExecCommands store while starting the exec process only serves to
block unrelated operations on the container for an extended period of
time.

from regressing in the future.

Change the log-level for messages about starting the managed containerd instance

the `--log-level` flag overrides whatever is in the containerd configuration file;
f033f6ff85/cmd/containerd/command/main.go (L339-L352)
Given that we set that flag when we start the containerd binary, there is no need
to write it both to the generated config-file and pass it as flag.
This patch also slightly changes the behavior; as both dockerd and containerd use
"info" as default log-level, don't set the log-level if it's the default.

Containerd, like dockerd has a OOMScore configuration option to adjust its own
OOM score. In dockerd, this option was added when default installations were not
yet running the daemon as a systemd unit, which made it more complicated to set
the score, and adding a daemon option was convenient.
A binary adjusting its own score has been frowned upon, as it's more logical to
make that the responsibility of the process manager _starting_ the daemon, which
is what we did for dockerd in 21578530d7.
There have been discussions on deprecating the daemon flag for dockerd, and
similar discussions have been happening for containerd.
This patch changes how we set the OOM score for the containerd child process,
and to have dockerd (supervisor) set the OOM score, as it's acting as process
manager in this case (performing a role similar to systemd otherwise).
With this patch, the score is still adjusted as usual, but not written to the
containerd configuration file;
dockerd --oom-score-adjust=-123
cat /proc/$(pidof containerd)/oom_score_adj
-123
As a follow-up, we may consider to adjust the containerd OOM score based on the
daemon's own score instead of on the `cli.OOMScoreAdjust` configuration so that
we will also adjust the score in situations where dockerd's OOM score was set
through other ways (systemd or manually adjusting the cgroup). A TODO was added
for this.

The existing implementation used a `nil` value for the CRI plugin's configuration
to indicate that the plugin had to be disabled. Effectively, the `Plugins` value
was only used as an intermediate step, only to be removed later on, and to instead
add the given plugin to `DisabledPlugins` in the containerd configuration.
This patch removes the intermediate step; as a result we also don't need to mask
the containerd `Plugins` field, which was added to allow serializing the toml.
A code comment was added as well to explain why we're (currently) disabling the
CRI plugin by default, which may help future visitors of the code to determin
if that default is still needed.

Contrary to popular belief, the OCI Runtime specification does not
specify the command-line API for runtimes. Looking at containerd's
architecture from the lens of the OCI Runtime spec, the _shim_ is the
OCI Runtime and runC is "just" an implementation detail of the
io.containerd.runc.v2 runtime. When one configures a non-default runtime
in Docker, what they're really doing is instructing Docker to create
containers using the io.containerd.runc.v2 runtime with a configuration
option telling the runtime that the runC binary is at some non-default
path. Consequently, only OCI runtimes which are compatible with the
io.containerd.runc.v2 shim, such as crun, can be used in this manner.
Other OCI runtimes, including kata-containers v2, come with their own
containerd shim and are not compatible with io.containerd.runc.v2.
As Docker has not historically provided a way to select a non-default
runtime which requires its own shim, runtimes such as kata-containers v2
could not be used with Docker.
Allow other containerd shims to be used with Docker; no daemon
configuration required. If the daemon is instructed to create a
container with a runtime name which does not match any of the configured
or stock runtimes, it passes the name along to containerd verbatim. A
user can start a container with the kata-containers runtime, for
example, simply by calling
docker run --runtime io.containerd.kata.v2
Runtime names which containerd would interpret as a path to an arbitrary
binary are disallowed. While handy for development and testing it is not
strictly necessary and would allow anyone with Engine API access to
trivially execute any binary on the host as root, so we have decided it
would be safest for our users if it was not allowed.
It is not yet possible to set an alternative containerd shim as the
default runtime; it can only be configured per-container.

Wrap the libsystemd journal reading functionality in a more idiomatic Go
API and refactor the journald logging driver's ReadLogs implementation
to use the wrapper. Rewrite the parts of the ReadLogs implementation in
Go which were previously implemented in C as part of the cgo preamble.
Separating the business logic from the cgo minutiae should hopefully
make the code more accessible to a wider audience of developers for
reviewing the code and contributing improvements.
The structure of the ReadLogs implementation is retained with few
modifications. Any ignored errors were also ignored before the refactor;
the explicit error return values afforded by the sdjournal wrapper makes
this more obvious.
The package github.com/coreos/go-systemd/v22/sdjournal also provides a
more idiomatic Go wrapper around libsystemd. It is unsuitable for our
needs as it does not expose wrappers for the sd_journal_process and
sd_journal_get_fd functions.

In network node change test, the expected behavior is focused on how many nodes
left in networkDB, besides timing issues, things would also go tricky for a
leave-then-join sequence, if the check (counting the nodes) happened before the
first "leave" event, then the testcase actually miss its target and report PASS
without verifying its final result; if the check happened after the 'leave' event,
but before the 'join' event, the test would report FAIL unnecessary;
This code change would check both the db changes and the node count, it would
report PASS only when networkdb has indeed changed and the node count is expected.

Before this change there was a race condition between State.Wait reading
the exit code from State and the State being changed instantly after the
change which ended the State.Wait.
Now, each State.Wait has its own channel which is used to transmit the
desired StateStatus at the time the state transitions to the awaited
one. Wait no longer reads the status by itself so there is no race.
The issue caused the `docker run --restart=always ...' to sometimes exit
with 0 exit code, because the process was already restarted by the time
State.Wait got the chance to read the exit code.

- Identified MUST be alphanumeric

- MUST be followed by at least one `<option>`
- Optionally additional `<options>` (comma-separated)
- Optionally followed by a comment
Any other format will not be considered a machine-readable comment by `gofmt`,

We have just released Go versions 1.18.4 and 1.17.12, minor point releases. These
minor releases include 9 security fixes following the security policy:
- net/http: improper sanitization of Transfer-Encoding header
The HTTP/1 client accepted some invalid Transfer-Encoding headers as indicating
a "chunked" encoding. This could potentially allow for request smuggling, but
only if combined with an intermediate server that also improperly failed to
reject the header as invalid.
This is CVE-2022-1705 and https://go.dev/issue/53188.
- When `httputil.ReverseProxy.ServeHTTP` was called with a `Request.Header` map
containing a nil value for the X-Forwarded-For header, ReverseProxy would set
the client IP as the value of the X-Forwarded-For header, contrary to its
documentation. In the more usual case where a Director function set the
X-Forwarded-For header value to nil, ReverseProxy would leave the header
unmodified as expected.
This is https://go.dev/issue/53423 and CVE-2022-32148.

This is the third release of the 1.1.z series of runc, and contains
various minor improvements and bugfixes.
- Our seccomp `-ENOSYS` stub now correctly handles multiplexed syscalls on
s390 and s390x. This solves the issue where syscalls the host kernel did not
support would return `-EPERM` despite the existence of the `-ENOSYS` stub
code (this was due to how s390x does syscall multiplexing).
- Retry on dbus disconnect logic in libcontainer/cgroups/systemd now works as
intended; this fix does not affect runc binary itself but is important for
libcontainer users such as Kubernetes.
- Inability to compile with recent clang due to an issue with duplicate
constants in libseccomp-golang.
- When using systemd cgroup driver, skip adding device paths that don't exist,
to stop systemd from emitting warnings about those paths.
- Socket activation was failing when more than 3 sockets were used.
- Various CI fixes.
- Allow to bind mount `/proc/sys/kernel/ns_last_pid` to inside container.
- runc static binaries are now linked against libseccomp v2.5.4.

iptables package has a function `detectIptables()` called to initialize
some local variables. Since v20.10.0, it first looks for iptables bin,
then ip6tables and finally it checks what iptables flags are available
(including -C). It early exits when ip6tables isn't available, and
doesn't execute the last check.
To remove port mappings (eg. when a container stops/dies), Docker
first checks if those NAT rules exist and then deletes them. However, in
the particular case where there's no ip6tables bin available, iptables
`-C` flag is considered unavailable and thus it looks for NAT rules by
using some substring matching. This substring matching then fails
because `iptables -t nat -S POSTROUTING` dumps rules in a slighly format
than what's expected.
For instance, here's what `iptables -t nat -S POSTROUTING` dumps:
```
-A POSTROUTING -s 172.18.0.2/32 -d 172.18.0.2/32 -p tcp -m tcp --dport 9999 -j MASQUERADE
```
And here's what Docker looks for:
```
POSTROUTING -p tcp -s 172.18.0.2 -d 172.18.0.2 --dport 9999 -j MASQUERADE
```
Because of that, those rules are considered non-existant by Docker and
thus never deleted. To fix that, this change reorders the code in
`detectIptables()`.
Fixes#42127.

Starting with the 22.06 release, buildx is the default client for
docker build, which uses BuildKit as builder.
This patch changes the default builder version as advertised by
the daemon to "2" (BuildKit), so that pre-22.06 CLIs with BuildKit
support (but no buildx installed) also default to using BuildKit
when interacting with a 22.06 (or up) daemon.

While doing a boltdb operation and if the bucket is not found
we should not return a boltdb specific bucket not found error
because this causes leaky abstraction where in the user of libkv
needs to know about boltdb and import boltdb dependencies
neither of which is desirable. Replaced all the bucket not found
errors with the more generic `store.ErrKeyNotFound` error which
is more appropriate.

When using AtomicPut with 'previous' set at nil, it interprets
that the Key should be created with the AtomicPut. Instead of

This commit migrates the old 'go-etcd' client, which is deprecated
to the new 'coreos/etcd/client'.
One notable change is the ability to specify an 'IsDir' parameter
to the 'Put' call. This allows to circumvent the limitations of etcd
regarding the key/directory distinction while setting up Watches on
a directory. A conservative measure to set up a watch that should be
used the same way for etcd/consul/zookeeper is to enforce the 'IsDir'
parameter with 'WriteOptions' on 'Put' to avoid the 'NotANode' error
thrown by etcd on Watch call. Consul and zookeeper are not using the
'IsDir' parameter.

AtomicPut can now be used to Compare-and-Swap against the state
where the key doesn't yet exist. E.g. a race where two clients
create the same key: one succeeds, the other fails.
Pass nil for the previous argument of AtomicPut for this
behavior. Before, this would cause an error.
Implements this change for all three backends.
