Attached is a patch to fix the issue in hirsute. Assuming this is approved, I have also prepared the SRUs for focal and groovy.
** Patch added: "Hirsute debdiff" https://bugs.launchpad.net/ubuntu/+source/procps/+bug/1874824/+attachment/5480543/+files/lp1874824_hirsute.debdiff -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to procps in Ubuntu. https://bugs.launchpad.net/bugs/1874824 Title: pgrep reports error "cannot allocate" when run without stack limit Status in procps package in Ubuntu: In Progress Status in procps source package in Focal: In Progress Status in procps source package in Groovy: In Progress Status in procps source package in Hirsute: In Progress Status in procps package in Debian: New Bug description: [Impact] - Users who have ulimit set high would see either slow or failed pgrep and pkill commands - Users who have ulimit set to unlimited would see failed pgrep and pkill commands - This bug occurs because the behavior of sysconf(_SC_ARG_MAX) changed with a newer version of the kernel. [Test Case] - set the ulimit to unlimited by running `ulimit -S -s unlimited` - run `pgrep bash` to see that the "cannot allocate" error is printed and the command has failed. [Where Problems Could Occur] - We have set upper and lower limits on the size of the malloc, but if further kernel versions break the call to sysconf in unexpected ways we could still see problems. [Original Description] If you have no stack limit (ulimit -S -s unlimited), any pgrep call will fail with an error: > pgrep vim pgrep: cannot allocate 4611686018427387903 bytes If you have a high stack limit (e.g. ulimit -S -s 500000), pgrep is very slow: > time pgrep vim 2196 real 8.48s user 8.40s syst 0.07s busy 99% rmem 253444 The relevant upstream bug report could be: https://gitlab.com/procps-ng/procps/-/issues/152 Archlinux bug report: https://bugs.archlinux.org/task/66093 procps: Installed: 2:3.3.16-1ubuntu2 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/procps/+bug/1874824/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
