Description Florian Weimer 2021-07-19 10:40:28 UTC

+++ This bug was initially created as a clone of Bug #1983639 +++

The Lua code to remove ELF multilibs does not iterate over all glibc-hwcaps subdirectories, so it misses the power9 multilib added in bug 1956357.

Comment 1 Florian Weimer 2021-07-21 19:13:40 UTC

glibc-2.33.9000-46.el9 (in a side tag only, so not moving to MODIFIED yet) contains the fix.

Comment 2 Alois Mahdal 2021-07-24 09:08:40 UTC

It's still failing in el8toel9 upgrade:

Found the bug:

 end

The old libc-2.28.so names are not removed because the pattern for them is overwritten. The new version uses the Lua table append idiom.

I'll see if I can spin a new build for testing.

Comment 4 Florian Weimer 2021-07-24 12:26:28 UTC

glibc-2.33.9000-49.el9 is the first build with this fix. Alois, would you mind checking again? Thanks.

Comment 5 Alois Mahdal 2021-07-27 07:51:31 UTC

With glibc-2.33.9000-49.el9 the transaction was completed successfully.


Thanks!

Comment 8 Florian Weimer 2021-08-02 11:00:33 UTC

glibc-2.33.9000-55.el9 with this change is in gating, via rhel-9.0.0-beta-build-sidetag-86604-stack-gate.
