[Desktop-packages] [Bug 2058881] Re: [snap] Allow chromium snap to access Pressure Stall Information (PSI)
I've not observed any problems or hindrance as a result of these denials, no. Just more noise and thought maybe Chromium was going to use the pressure stall information for something useful like for the selection of which tabs/process to kill off when the system is experiencing pressure in either CPU, I/O, and/or memory. But all good if it does not and it does not plan to. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/2058881 Title: [snap] Allow chromium snap to access Pressure Stall Information (PSI) Status in chromium-browser package in Ubuntu: Confirmed Bug description: Hi, Currently seeing this: | Mar 25 16:12:23 dharkan.local kernel: audit: type=1400 audit(1711343543.539:657): apparmor="DENIED" operation="open" class="file" profile="snap.chromium.chromium" name="/proc/pressure/cpu" pid=63335 comm="ThreadPoolForeg" requested_mask="r" denied_mask="r" fsuid=3134 ouid=0 | Mar 25 16:12:23 dharkan.local kernel: audit: type=1400 audit(1711343543.539:658): apparmor="DENIED" operation="open" class="file" profile="snap.chromium.chromium" name="/proc/pressure/io" pid=63335 comm="ThreadPoolForeg" requested_mask="r" denied_mask="r" fsuid=3134 ouid=0 | Mar 25 16:12:23 dharkan.local kernel: audit: type=1400 audit(1711343543.539:659): apparmor="DENIED" operation="open" class="file" profile="snap.chromium.chromium" name="/proc/pressure/memory" pid=63335 comm="ThreadPoolForeg" requested_mask="r" denied_mask="r" fsuid=3134 ouid> It seems the AppAmor profile should be updated to allow Chromium access to the pressure stall information for it to monitor and manage it's processes?

I reproduced that now. Do you observe any problem or hindrance as a result of those denials? I had a look at the source code and it seems that it doesn't actually use that information for load balancing or anything of the sorts, but actually only for informational purposes, namely for assembling histograms and reporting the results to the so called UMA, User Metrics Analysis according to the developer's glossary, for instance if the user chooses to report a session crash back to Google. ** Changed in: chromium-browser (Ubuntu) Importance: Undecided => Wishlist -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/2058881 Title: [snap] Allow chromium snap to access Pressure Stall Information (PSI) Status in chromium-browser package in Ubuntu: Confirmed Bug description: Hi, Currently seeing this: | Mar 25 16:12:23 dharkan.local kernel: audit: type=1400 audit(1711343543.539:657): apparmor="DENIED" operation="open" class="file" profile="snap.chromium.chromium" name="/proc/pressure/cpu" pid=63335 comm="ThreadPoolForeg" requested_mask="r" denied_mask="r" fsuid=3134 ouid=0 | Mar 25 16:12:23 dharkan.local kernel: audit: type=1400 audit(1711343543.539:658): apparmor="DENIED" operation="open" class="file" profile="snap.chromium.chromium" name="/proc/pressure/io" pid=63335 comm="ThreadPoolForeg" requested_mask="r" denied_mask="r" fsuid=3134 ouid=0 | Mar 25 16:12:23 dharkan.local kernel: audit: type=1400 audit(1711343543.539:659): apparmor="DENIED" operation="open" class="file" profile="snap.chromium.chromium" name="/proc/pressure/memory" pid=63335 comm="ThreadPoolForeg" requested_mask="r" denied_mask="r" fsuid=3134 ouid> It seems the AppAmor profile should be updated to allow Chromium access to the pressure stall information for it to monitor and manage it's processes?
