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.

This is the eleventh patch release in the 1.1.z release branch of runc.
It primarily fixes a few issues with runc's handling of containers that
are configured to join existing user namespaces, as well as improvements
to cgroupv2 support.
- Fix several issues with userns path handling.
- Support memory.peak and memory.swap.peak in cgroups v2.
Add swapOnlyUsage in MemoryStats. This field reports swap-only usage.
For cgroupv1, Usage and Failcnt are set by subtracting memory usage
from memory+swap usage. For cgroupv2, Usage, Limit, and MaxUsage
are set.
- build(deps): bump github.com/cyphar/filepath-securejoin.
- release notes: https://github.com/opencontainers/runc/releases/tag/v1.1.11
- full diff: https://github.com/opencontainers/runc/compare/v1.1.10...v1.1.11

This package provided utilities to obtain the apparmor_parser version, as well
as loading a profile.
Commit e3e715666f (included in v24.0.0 through
bfffb0974e) deprecated GetVersion, as it was no
longer used, which made LoadProfile the only utility remaining in this package.
LoadProfile appears to have no external consumers, and the only use in our code
is "profiles/apparmor".
This patch moves the remaining code (LoadProfile) to profiles/apparmor as a
non-exported function, and deletes the package.

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

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
WARN[2023-12-29T11:38:30.752523879Z] ffailed to lookup default userland-proxy binary error="exec: \"docker-proxy\": executable file not found in $PATH"
configuration OK
Speficying a non-absolute path produces an error:
dockerd --userland-proxy-path=docker-proxy --validate
invalid userland-proxy-path: must be an absolute path: docker-proxy
Befor this patch, we would not validate this path, which would allow the daemon
to start, but fail to map a port;
docker run -d -P nginx:alpine
4f7b6589a1680f883d98d03db12203973387f9061e7a963331776170e4414194

Specifying an invalid userland-proxy-path produces an error as well:

The cleanup function never returns an error, so didn't add much value. This
patch removes the closure, and calls it inline to remove the extra
indirection, and removes the error which would never be returned.

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.

If IPv6 is enabled for a bridge network, by the time configuration
is applied, the bridge will always have an address. Assert that, by
raising an error when the configuration is validated.
Use that to simplify the logic used to calculate which addresses
should be assigned to a bridge. Also remove a redundant check in
setupGatewayIPv6() and the error associated with it.
Fix unit tests that enabled IPv6, but didn't supply an IPv6 IPAM
address/pool. Before this change, these tests passed but silently
left the bridge without an IPv6 address.
(The daemon already ensured there was an IPv6 address, this change
does not add a new restriction on config at that level.)

expected, they'd always pass - because 'parseNetworkOptions()' called

No more concept of "anonymous endpoints". The equivalent is now an
endpoint with no DNSNames set.
Some of the code removed by this commit was mutating user-supplied
endpoint's Aliases to add container's short ID to that list. In order to
preserve backward compatibility for the ContainerInspect endpoint, this
commit also takes care of adding that short ID (and the container
hostname) to `EndpointSettings.Aliases` before returning the response.
