Description Chris Denice 2021-09-06 09:30:37 CEST

The program pgred returns a pid from a running process. Check what is running with top for instance, and enter:

pgrep systemd

The normal output is a list of pids.

Now, in a terminal, set the stacksize to unlimited:

ulimit -s unlimited

and try the same:

pgrep systemd
pgrep: cannot allocate 4611686018427387903 bytes

Bug is known and has been fixed upstream, as well as in Cauldron.

Comment 1 Chris Denice 2021-09-06 09:38:54 CEST

Here we go, procps-ng version 3.3.17 landing in updates_testing. To test, reproduce the steps mentioned in the bug report. This version should work even if ulimit -s unlimited has been set before.





Suggested advisory:
========================

Updated procps-ng package fixing a fatal issue preventing pgrep to run on unlimited stack size.

========================

Updated packages in core/updates_testing:
========================
lib(64)procps8-3.3.17-1.mga8
lib(64)procps-devel-3.3.17-1.mga8
procps-ng-3.3.17-1.mga8

MGA8-64 Plasma on Lenovo B50
No installation issues.
$ pgrep systemd

523
565

3198
$ ulimit -s unlimited
$ pgrep systemd

So update is OK.
