Do not handle SIGURG on Linux, as in go1.14+, the go runtime issues
SIGURG as an interrupt to support preemptable system calls on Linux.
This issue was caught in TestCatchAll, which could fail when updating to Go 1.14 or above;

Release notes:
This release of runc contains a fix for CVE-2021-30465, and users are
strongly recommended to update (especially if you are providing
semi-limited access to spawn containers to untrusted users).
Aside from this security fix, only a few other changes were made since
v1.0.0-rc94 (the only user-visible change was the addition of support
for defaultErrnoRet in seccomp profiles).

[20.10 backport] bump up rootlesskit to v0.14.2 (Fix `Timed out proxy starting the userland proxy.` error with `DOCKERD_ROOTLESS_ROOTLESSKIT_PORT_DRIVER=slirp4netns`)
Whether or not the command path is in the error message is a an
implementation detail.
For example, on Windows the only reason this ever matched was because it
dumped the entire container config into the error message, but this had
nothing to do with the actual error.

This test has been flaky for a long time, failing with:
--- FAIL: TestInspect (12.04s)
inspect_test.go:39: timeout hit after 10s: waiting for tasks to enter run state. task failed with error: task: non-zero exit (1)
While looking through logs, noticed tasks were started, entering RUNNING stage,
and then exited, to be started again.
state.transition="STARTING->RUNNING"
...
msg="fatal task error" error="task: non-zero exit (1)"
...
state.transition="RUNNING->FAILED"
Looking for possible reasons, first considering network issues (possibly we ran
out of IP addresses or networking not cleaned up), then I spotted the issue.
The service is started with;
Command: []string{"/bin/top"},
Args: []string{"-u", "root"},
The `-u root` is not an argument for the service, but for `/bin/top`. While the
Ubuntu/Debian/GNU version `top` has a -u/-U option;
docker run --rm ubuntu:20.04 top -h 2>&1 | grep '\-u'
top -hv | -bcEHiOSs1 -d secs -n max -u|U user -p pid(s) -o field -w [cols]
The *busybox* version of top does not:
docker run --rm busybox top --help 2>&1 | grep '\-u'
So running `top -u root` would cause the task to fail;
docker run --rm busybox top -u root
top: invalid option -- u
...
echo $?
1
As a result, the service went into a crash-loop, and because the `poll.WaitOn()`
was running with a short interval, in many cases would _just_ find the RUNNING
state, perform the `service inspect`, and pass, but in other cases, it would not
be that lucky, and continue polling untill we reached the 10 seconds timeout,
and mark the test as failed.
Looking for history of this option (was it previously using a different image?) I
found this was added in 6cd6d8646a, but probably
just missed during review.
Given that the option is only set to have "something" to inspect, I replaced
the `-u root` with `-d 5`, which makes top refresh with a 5 second interval.
Note that there is another test (`TestServiceListWithStatuses) that uses the same
spec, however, that test is skipped based on API version of the test-daemon, and
(to be looked into), when performing that check, no API version is known, causing
the test to (always?) be skipped:
=== RUN TestServiceListWithStatuses
--- SKIP: TestServiceListWithStatuses (0.00s)
list_test.go:34: versions.LessThan(testEnv.DaemonInfo.ServerVersion, "1.41")

Fix issue 41762
Cherry-pick "drivers: btrfs: Allow unprivileged user to delete subvolumes" from containers/storage
831e32b6bd
> In btrfs, subvolume can be deleted by IOC_SNAP_DESTROY ioctl but there
> is one catch: unprivileged IOC_SNAP_DESTROY call is restricted by default.
>
> This is because IOC_SNAP_DESTROY only performs permission checks on
> the top directory(subvolume) and unprivileged user might delete dirs/files
> which cannot be deleted otherwise. This restriction can be relaxed if
> user_subvol_rm_allowed mount option is used.
>
> Although the above ioctl had been the only way to delete a subvolume,
> btrfs now allows deletion of subvolume just like regular directory
> (i.e. rmdir sycall) since kernel 4.18.
>
> So if we fail to cleanup subvolume in subvolDelete(), just fallback to
> system.EnsureRmoveall() to try to cleanup subvolumes again.
> (Note: quota needs privilege, so if quota is enabled we do not fallback)
>
> This fix will allow non-privileged container works with btrfs backend.
