Description

This update for crun fixes the following issues:

Update to 1.20:

* krun: fix CVE-2025-24965. The .krun_config.json file could be created

outside of the container rootfs. (bsc#1237421)

* cgroup: reverted the removal of tun/tap from the default allow list,

this was done in crun-1.5. The tun/tap device is now added by default

again.

* CRIU: do not set network_lock unless explicitly specified.

* status: disallow container names containing slashes in their name.

* linux: Improved error message when failing to set the

net.ipv4.ping_group_range sysctl.

* scheduler: Ignore ENOSYS errors when resetting the CPU affinity mask.

* linux: return a better error message when pidfd_open fails with EINVAL.

* cgroup: display the absolute path to cgroup.controllers when a

controller is unavailable.

* exec: always call setsid. Now processes created through exec get the

correct process group id.
