Title:
AppArmor denies crun sending signals to containers
Status in alsa-driver package in Ubuntu:
Confirmed
Status in runc package in Ubuntu:
Confirmed
Bug description:
Environment: k8s 1.30.2, containerd 1.7.12 (package in ubuntu repo)
When I do a k8s deployment update, the old pods stay in 'Terminating'
status. The /var/log/syslog has the following messages:
2024-07-05T15:52:07.892132+08:00 km kernel: audit: type=1400
audit(1720165927.890:2191): apparmor="DENIED" operation="signal"
class="signal" profile="cri-containerd.apparmor.d" pid=134029
comm="runc" requested_mask="receive" denied_mask="receive" signal=kill
peer="runc"
Workaround:
currently I disable the apparmor.service and reboot the system.
