Subject: prctl call wrongly succeeds on HPPA?
Date: Tue, 31 Oct 2023 04:32:36 +0000	[thread overview]
Message-ID: <87lebjz9z6.fsf@gentoo.org> (raw)

I recently hit an issue with systemd-254 which tries to use the new
prctl(PR_SET_MDWE) for systemd's MemoryDenyWriteExecute functionality.

On HPPA, we still need executable stacks, so this option doesn't work
and leads to a segfault on boot.

Should this call be succeeeding on HPPA, or should we reject it for
now until we have things wired up?

Reported to systemd at https://github.com/systemd/systemd/issues/29775.

thanks,
sam
