[Bug 1914044] Re: [SRU] gstreamer fails with "cannot allocate memory in static TLS block" error on aarch64

[Łukasz Zemczak]

Hello Alfonso, or anyone else affected,

Accepted glibc into focal-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/glibc/2.31-0ubuntu9.3
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: glibc (Ubuntu Focal)
       Status: Confirmed => Fix Committed

** Tags added: verification-needed verification-needed-focal

Title:
  [SRU] gstreamer fails with "cannot allocate memory in static TLS
  block" error on aarch64

Status in glibc package in Ubuntu:
  Fix Released
Status in glibc source package in Focal:
  Fix Committed
Status in glibc package in Debian:
  Fix Released

Bug description:
  [Impact]

  gstreamer cannot load some plugins on 20.04, aarch64 due to TLS memory
  exhaustion, so these plugins cannot be used. See LP: #1846837 and LP:
  #1914030.

  This is solved apparently on glibc 2.32:
  https://sourceware.org/bugzilla/show_bug.cgi?id=25051
  by patch
  https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=ffb17e7ba3a5ba9632cee97330b325072fbe41dd

  [Test Case]

  Running totem-video-thumbnailer shows TLS error in the version not
  fixed, generates thumbnail with the fixed version:

  $ sudo apt -y install totem gstreamer1.0-libav
  ...
  $ wget https://ia800201.us.archive.org/12/items/BigBuckBunny_328/BigBuckBunny_512kb.mp4
  ...
  $ totem-video-thumbnailer BigBuckBunny_512kb.mp4 thumbnail.png
  ...
  (totem-video-thumbnailer:3602): GStreamer-WARNING **: 18:36:10.466: Failed to load plugin '/usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstlibav.so': /lib/aarch64-linux-gnu/libgomp.so.1: cannot allocate memory in static TLS block
  ...

  [Where problems could occur]

  This is delicate code in glibc with quite regression potential. Said
  this, the code is in the next major release (2.32, while focal has
  2.31), which has been running groovy for a while.

  Also, apparently there is a 2.31 patch for groovy, before it moved to
  2.32: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=964141
