Commit 483aa6294b introduced a regression, causing
spurious warnings to be shown when starting a daemon for the first time after
a fresh install:
docker info
...
WARNING: IPv4 forwarding is disabled
WARNING: bridge-nf-call-iptables is disabled
WARNING: bridge-nf-call-ip6tables is disabled
The information shown is incorrect, as checking the corresponding options on
the system, shows that these options are available:
cat /proc/sys/net/ipv4/ip_forward
1
cat /proc/sys/net/bridge/bridge-nf-call-iptables
1
cat /proc/sys/net/bridge/bridge-nf-call-ip6tables
1
The reason this is failing is because the daemon itself reconfigures those
options during networking initialization in `configureIPForwarding()`;
cf4595265e/libnetwork/drivers/bridge/setup_ip_forwarding.go (L14-L25)
Network initialization happens in the `daemon.restore()` function within `daemon.NewDaemon()`:
cf4595265e/daemon/daemon.go (L475-L478)
However, 483aa6294b moved detection of features
earlier in the `daemon.NewDaemon()` function, and collects the system information
(`d.RawSysInfo()`) before we enter `daemon.restore()`;
cf4595265e/daemon/daemon.go (L1008-L1011)
For optimization (collecting the system information comes at a cost), those
results are cached on the daemon, and will only be performed once (using a
`sync.Once`).
This patch:
- introduces a `getSysInfo()` utility, which collects system information without
caching the results
- uses `getSysInfo()` to collect the preliminary information needed at that
point in the daemon's lifecycle.
- moves printing warnings to the end of `daemon.NewDaemon()`, after all information
can be read correctly.

Note that Windows does not support options, so strictly doesn't need
to have this code, but keeping it in case we're adding support.

Unmounting does not depend on wether or not loading options failed.
This code-path seemed to be used as a "hack" to prevent hitting the
unmount on Windows (which does not support unmounting).
Moving it outside of the "if" to make more clear that it's independent
of loading the options.

Differentiate between Windows and Linux, as Windows doesn't support
options, so there's no need to save options to disk,

Instead of evaluating these paths each time (appending `_data`, or using
`filepath.Dir()` to find the root path from the `_data_` path).
This also removes the `root.DataPath()` utility, which is now no longer needed.

This way we can validate if Root supports quotaCtl, allowing us to
fail early, before creating any of the directories.

This moves validation of options to the start of the Create function
to prevent hitting the filesystem and having to remove the volume
from disk.
Also addressing some minor nits w.r.t. errors.

While the current code is correct (as errors.Wrap() returns nil if
err is nil), relying on this behavior has caused some confusion in
the past, resulting in regressions.
This patch makes the error-handling code slightly more idiomatic and
defensive against such regressions.

Since commit 2c4a868f64, Docker doesn't
use the value of net.ipv4.ip_local_port_range when choosing an ephemeral
port. This change reverts back to the previous behavior.
Fixes#43054.

Make finding the correct runtime image from image index
more compliant with OCI spec and match containerd implementation.
Changes:
- Manifest list is allowed to contain manifest lists
- Unknown mediatype inside manifest list is skipped instead of causing an error
- Platform in descriptor is optional

This attempts to fix CI flakiness on the TestRunContainerWithRmFlagCannotStartContainer
and TestRunContainerWithRmFlagExitCodeNotEqualToZero tests.
These tests;
- get a list of all container ID's
- run a container with `--rm`
- wait for it to exit
- checks that the list of all container IDs is empty
The last step assumes that no other tests are running on the same daemon; if
another test is running, there may be other containers present (unrelated to
the test).
This patch updates the tests to use a `docker inspect` to verify the container
no longer exists afterwards.

go1.18.3 (released 2022-06-01) includes security fixes to the crypto/rand,
crypto/tls, os/exec, and path/filepath packages, as well as bug fixes to the
compiler, and the crypto/tls and text/template/parse packages. See the Go
1.18.3 milestone on our issue tracker for details:
https://github.com/golang/go/issues?q=milestone%3AGo1.18.3+label%3ACherryPickApproved
Hello gophers,
We have just released Go versions 1.18.3 and 1.17.11, minor point releases.
These minor releases include 4 security fixes following the security policy:
- crypto/rand: rand.Read hangs with extremely large buffers
On Windows, rand.Read will hang indefinitely if passed a buffer larger than
1 << 32 - 1 bytes.
Thanks to Davis Goodin and Quim Muntal, working at Microsoft on the Go toolset,
for reporting this issue.
This is [CVE-2022-30634][CVE-2022-30634] and Go issue https://go.dev/issue/52561.
- crypto/tls: session tickets lack random ticket_age_add
Session tickets generated by crypto/tls did not contain a randomly generated
ticket_age_add. This allows an attacker that can observe TLS handshakes to
correlate successive connections by comparing ticket ages during session
resumption.
Thanks to GitHub user nervuri for reporting this.
This is [CVE-2022-30629][CVE-2022-30629] and Go issue https://go.dev/issue/52814.
- `os/exec`: empty `Cmd.Path` can result in running unintended binary on Windows
If, on Windows, `Cmd.Run`, `cmd.Start`, `cmd.Output`, or `cmd.CombinedOutput`
are executed when Cmd.Path is unset and, in the working directory, there are
binaries named either "..com" or "..exe", they will be executed.
Thanks to Chris Darroch, brian m. carlson, and Mikhail Shcherbakov for reporting
this.
This is [CVE-2022-30580][CVE-2022-30580] and Go issue https://go.dev/issue/52574.
- `path/filepath`: Clean(`.\c:`) returns `c:` on Windows
On Windows, the `filepath.Clean` function could convert an invalid path to a
valid, absolute path. For example, Clean(`.\c:`) returned `c:`.
Thanks to Unrud for reporting this issue.
This is [CVE-2022-29804][CVE-2022-29804] and Go issue https://go.dev/issue/52476.

Previously, with the patch from #43146, it was possible for a
network configured with a single ingress or load balancer on a
distribution which does not have the `ip_vs` kernel module loaded
by default to try to apply sysctls which did not exist yet, and
subsequently dynamically load the module as part of ipvs/netlink.go.
This module is vendored, and not a great place to try to tie back
into core libnetwork functionality, so also ensure that the sysctls
(which are idempotent) are called after ingress/lb creation once
`ipvs` has been initialized.
