Thanks for the merge request, Soumyadeep. Unfortunately we just missed the Snapd 2.74 cut, but I'm sure it will be there in 2.75.
** Description changed: + Merge request: https://github.com/canonical/snapd/pull/16463 + + --------- + Since my last reboot, Firefox has been logspamming my system with the following message: Dec 19 08:21:12 work kernel: audit: type=1400 audit(1766096472.659:55003): apparmor="DENIED" operation="open" class="file" profile="snap.firefox.firefox" name="/proc/pressure/memory" pid=13905 comm="MemoryPoller" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0 This message has occurred previously at a much lower frequency: $ journalctl --boot --dmesg | fgrep 'profile="snap.firefox.firefox" name="/proc/pressure/memory"' | wc -l 10255 $ zgrep 'profile="snap.firefox.firefox" name="/proc/pressure/memory"' kern.log* | cut -d: -f2- | cut -dT -f1 | sort | uniq -c - 1 2025-11-17 - 2 2025-11-24 - 8 2025-11-27 - 2 2025-12-05 - 2 2025-12-06 - 2690 2025-12-15 - 1513 2025-12-16 - 2405 2025-12-17 - 3362 2025-12-18 - 295 2025-12-19 + 1 2025-11-17 + 2 2025-11-24 + 8 2025-11-27 + 2 2025-12-05 + 2 2025-12-06 + 2690 2025-12-15 + 1513 2025-12-16 + 2405 2025-12-17 + 3362 2025-12-18 + 295 2025-12-19 I'm filing this against Firefox, since presumably it's responsible for supplying a correct AppArmor profile for itself, but it's possible that this has been activated by a kernel or AppArmor upgrade.
