As runc binary grows in size over time (new features, more
dependencies) some tests start to flake because of low memory limits.
One such test is "runc run (cgroup v2 resources.unified override)";
it obviously fails because of 1M memory limit:
> runc run failed: unable to start container process: container init was OOM-killed (memory limit too low?)
Increase the limits 4x. Do the same for the "unified only" test.
Fixes issue 5264.

When RUNC_USE_SYSTEMD is set, tests/rootless.sh is using
ssh -tt rootless@localhost
to run tests as rootless user. In this case, local environment is not
passed to the user's ssh session (unless explicitly specified), and so
the tests do not get ROOTLESS_FEATURES.
As a result, idmap-related tests are skipped when running as rootless
using systemd cgroup driver:
integration test (systemd driver)
...
[02] run rootless tests ... (idmap)
...
ok 286 runc run detached ({u,g}id != 0) # skip test requires rootless_idmap
...
Fix this by creating a list of environment variables needed by the
tests, and adding those to ssh command line (in case of ssh) or
exporting (in case of sudo) so both cases work similarly.
Also, modify disable_idmap to unset variables set in enable_idmap so
they are not exported at all if idmap is not in features.

When signal installation was moved to a goroutine for performance,
containers that exited quickly could complete before SIGCHLD was
registered, causing runc to hang waiting for the signal.
This fix ensures SIGCHLD is registered immediately in the main thread
before other signals are handled in the goroutine, maintaining performance
while guaranteeing no missed SIGCHLD notifications for fast-exiting
containers.

SCMP_ACT_KILL terminates the process with a fatal signal, which may
produce a core dump depending on the host configuration.
While this is harmless on ephemeral CI instances, it can leave unwanted
core files on developer or customer systems. It also interferes with
test environments that detect unexpected core dumps.

For some reason, dnf install still succeeds, but when the selinux tests
fail with:

All this is fixed once policycoreutils is added to the list of RPMS so
it is updated (from 3.9-3.el10 to 3.10-1.el10) during the same

When parsing mount options into recAttrSet and recAttrClr,
the code sets attr_clr to individual atime flags (e.g.
MOUNT_ATTR_NOATIME or MOUNT_ATTR_STRICTATIME) when clearing
atime attributes. However, this violates the kernel's
requirement documented in mount_setattr(2)[1]:
> Note that, since the access-time values are an enumeration
> rather than bit values, a caller wanting to transition to a
> different access-time setting cannot simply specify the
> access-time setting in attr_set, but must also include
> MOUNT_ATTR__ATIME in the attr_clr field. The kernel will
> verify that MOUNT_ATTR__ATIME isn't partially set in
> attr_clr (i.e., either all bits in the MOUNT_ATTR__ATIME
> bit field are either set or clear), and that attr_set
> doesn't have any access-time bits set if MOUNT_ATTR__ATIME
> isn't set in attr_clr.
Passing only a single atime flag (e.g. MOUNT_ATTR_RELATIME) in
attr_clr causes mount_setattr() to fail with EINVAL.
This change ensures that whenever an atime mode is updated,
attr_clr includes MOUNT_ATTR__ATIME to properly reset the
entire access-time attribute field before applying the new mode.

Go 1.24 is no longer supported, and Go 1.25 (which we use in Dockerfile
for official binaries) is not being tested against.
So remove Go 1.24.x and add Go 1.25.x.
We keep Go 1.23.x is this is a minimally required version for this

Since the recent CVE fixes, TestFdLeaksSystemd sometimes fails:
=== RUN TestFdLeaksSystemd
exec_test.go:1750: extra fd 9 -> /12224/task/13831/fd
exec_test.go:1753: found 1 extra fds after container.Run
--- FAIL: TestFdLeaksSystemd (0.10s)
It might have been caused by the change to the test code in commit
ff6fe13 ("utils: use safe procfs for /proc/self/fd loop code") -- we are
now opening a file descriptor during the logic to get a list of file
descriptors. If the file descriptor happens to be allocated to a
different number, you'll get an error.
Let's try to filter out the fd used to read a directory.
