Description Allison King 2026-03-17 16:34:29 UTC
This is a tracking bug for Change: Changes/Restrict ptrace by default
For more details, see: https://fedoraproject.org/wiki/Changes/Restrict_ptrace_by_default

By default, disable ''some'' debugging permissions for unprivileged users using a system-wide kernel setting, so malware cannot inspect other preexisting processes of an unprivileged user.  When debugging tools are installed, re-enable ''full'' normal functionality system-wide using a sysctl file, as is the status quo up to Fedora 44.

This is a ''compromise'' proposal to followup several failures to achieve a consensus.

If you encounter a bug related to this Change, please do not comment here. Instead create a new bug and set it to block this bug.

Hi all, is there an update for this change please? The code complete deadline has passed so if you need to retarget to F46 please let me know.

Comment 4 Frank Ch. Eigler 2026-08-31 11:48:55 UTC
elfutils 0.196 has completed the core of this work, and other components have started adopting the new Recommends/Requires as you can see the dependency tree above.

Comment 5 Fedora Blocker Bugs Application 2026-09-01 17:51:09 UTC
Proposed as a Freeze Exception for 45-beta by Fedora user fche using the blocker tracking app because:

 We'd like to land the new-stable elfutils in the f45 beta compose so the new yama/ptrace-related inter-rpm dependencies can be exercised.

AGREED AcceptedBetaFreezeException

Discussed at the 2026-09-07 (blocker / freeze exception) review meeting:

We believe that the impact risk is not that high.
