- Update to runc v1.1.0~rc1. Upstream changelog is available from
https://github.com/opencontainers/runc/releases/tag/v1.1.0-rc.1.

+ Add support for RDMA cgroup added in Linux 4.11.
* runc exec now produces exit code of 255 when the exec failed.
This may help in distinguishing between runc exec failures
(such as invalid options, non-running container or non-existent
binary etc.) and failures of the command being executed.
+ runc run: new --keep option to skip removal exited containers artefacts.
This might be useful to check the state (e.g. of cgroup controllers) after
the container hasexited.
+ seccomp: add support for SCMP_ACT_KILL_PROCESS and SCMP_ACT_KILL_THREAD
(the latter is just an alias for SCMP_ACT_KILL).
+ seccomp: add support for SCMP_ACT_NOTIFY (seccomp actions). This allows
users to create sophisticated seccomp filters where syscalls can be
efficiently emulated by privileged processes on the host.
+ checkpoint/restore: add an option (--lsm-mount-context) to set
a different LSM mount context on restore.
+ intelrdt: support ClosID parameter.
+ runc exec --cgroup: an option to specify a (non-top) in-container cgroup
to use for the process being executed.
+ cgroup v1 controllers now support hybrid hierarchy (i.e. when on a cgroup v1
machine a cgroup2 filesystem is mounted to /sys/fs/cgroup/unified, runc
run/exec now adds the container to the appropriate cgroup under it).
+ sysctl: allow slashes in sysctl names, to better match sysctl(8)'s
behaviour.
+ mounts: add support for bind-mounts which are inaccessible after switching
the user namespace. Note that this does not permit the container any
additional access to the host filesystem, it simply allows containers to
have bind-mounts configured for paths the user can access but have
restrictive access control settings for other users.
+ Add support for recursive mount attributes using mount_setattr(2). These
have the same names as the proposed mount(8) options -- just prepend r
to the option name (such as rro).
+ Add runc features subcommand to allow runc users to detect what features
runc has been built with. This includes critical information such as
supported mount flags, hook names, and so on. Note that the output of this
command is subject to change and will not be considered stable until runc
1.2 at the earliest. The runtime-spec specification for this feature is
being developed in opencontainers/runtime-spec#1130.
* system: improve performance of /proc/$pid/stat parsing.
* cgroup2: when /sys/fs/cgroup is configured as a read-write mount, change
the ownership of certain cgroup control files (as per
/sys/kernel/cgroup/delegate) to allow for proper deferral to the container
process.
* runc checkpoint/restore: fixed for containers with an external bind mount
which destination is a symlink.
* cgroup: improve openat2 handling for cgroup directory handle hardening.
runc delete -f now succeeds (rather than timing out) on a paused
container.
* runc run/start/exec now refuses a frozen cgroup (paused container in case of
exec). Users can disable this using --ignore-paused.
- Update version data embedded in binary to correctly include the git commit of
the release.
- Drop runc-rpmlintrc because we don't have runc-test anymore.
