Bug Description

SRU Justification: Regression in GLX handling causes non-local X applications to die with BadRequest error when attempting DRI.

Regression potential: low. Patch only affects the DRI2Connect error handler, causing it to swallow the BadRequest generated when attempting to use the DRI2 extension on a remote server. This error is then processed further up the mesa codestack.

Original report:
With LTSP on natty i am unable to start compiz.

I tried with 2 thin clients and a laptop that where working on maverick:

here is a easy way to reproduce the problem without a ltsp setup

on the first computer:
1 ) sudo vim /usr/share/gdm/gdm.schemas
change :

<schema>
<key>security/DisallowTCP</key>
<signature>b</signature>
<default>true</default>
</schema>

to

<schema>
<key>security/DisallowTCP</key>
<signature>b</signature>
<default>false</default>
</schema>

2) logout
3) log in
4) in a console run : $ xhost +

5) on another computer: DISPLAY=<ip of the first computer>:0 glxinfo
computer1 $ DISPLAY=X.X.X.X:0 glxinfo
name of display: 10.145.0.54:0.0
X Error of failed request: BadRequest (invalid request code or no such operation)
  Major opcode of failed request: 137 (DRI2)
  Minor opcode of failed request: 1 (DRI2Connect)
  Serial number of failed request: 18
  Current serial number in output stream: 18

6) when connected via ssh on the same computer, running the same command works.

@Chris, sounds like this bug is fixed upstream; can you confirm the upstream patch is included in our merge? Also, check if this would be worth an SRU.

Hm. It looks like the patch got stuck in the mesa-dev and quietly died. I think I've addressed the review comments and resubmitted the patch. It certainly looks like an SRU candidate.

---------------
mesa (7.10.3-0ubuntu1) oneiric; urgency=low

  * New upstream 7.10.3 bugfix release.
   - Fixes infinite loop in GLSL compiler (LP: #788730)
  * Merge with Debian unstable. Remaining Ubuntu changes:
   - debian/control
      + Drop lesstif-dev from Build-Depends; it's in Universe.
      + Comment out GLw libs since it depends on lesstif-dev.
      + Drop i686 swx11 libgl package.
      + Add libdrm-dev to mesa-common-dev Depends.
    - debian/rules
      + Use --disable-glw for swx11 targets too.
      + Don't enable motif for swx11 targets.
      + Use lzma compression for binary debs to save CD space.
      + Drop unloved mach64 driver.
      + Install both r300/r300g and r600/r600g
      + Use --enable-shared-dricore to claw back CD space.
    - debian/patches
      + 100_no_abi_tag.patch
      + 101_ubuntu_hidden_glname.patch
      + 103_savage-expose_fbmodes_with_nonzero_alpha.patch
    - rules, libgl1-mesa-{glx,dev,swx11,swx11-dev}.install.in,
      libgl1-mesa-{glx,swx11}.{postinst,prerm}, libgl1-mesa-dev.links.in:
      Install libGL.so* in /usr/lib/mesa to allow things to work with
      alternatives.
    - debian/not-installed:
      + Drop i686 files; we don't build 686-optimised packages in the first
        place.
    - debian/gbp.conf
      + Point at Ubuntu branch to make git-buildpackage less narky.
    - debian/patches/105_use_shared_libdricore.patch, debian/rules:
      + Link DRI drivers against shared dricore routines to save CD space.
    - debian/patches/109_fix_length_of_glxgetfbconfigssgix.patch:
      Fix "BadLength (poly request too large or internal Xlib length"
      when using non-C, non-en locales. (LP 714280)
    - debian/patches/108_fix_leaks_dri2_screen_creation.patch: Cherrypick
      to fix some leaks in DRI2 screen creation failure paths.
    - 114_intel_dri_renderer_string.diff: Re-add "GEM" to the dri renderer
      string of the intel driver. (LP 753370)
    - 113_fix_tls.diff: Fix crashes in unrelated code due to TLS usage.
  * debian/rules:
  * debian/libgl1-mesa-dri-experimental.install.in:
    - Ship i915g in the experimental package. We're already building it,
      and it's apparently now comparable to i915c.
  * debian/control:
  * debian/libgl1-mesa-dri-experimental.install.in:
  * debian/libgl1-mesa-dri.install.linux.in:
    - Move nouveau gallium driver from -dri-experimental to -dri. Upstream
      is no longer adamant that bugs should be ignored. Try installing it by
      default to get a better Unity experience OOTB. (LP: #759562)
  * debian/libgl1-mesa-dri-experimental.install.in:
  * debian/libgl1-mesa-dri.install.linux.in:
    - Move r300/r600 classic drivers to -experimental. They're not supported.
      Shave another ~1MB off the CD!
  * debian/control:
    - Add new bison and flex build-depends.
  * debian/patches/115_llvm_dynamic_linking.diff
    - Dynamically link DRI drivers to libllvm. Saves ~6MiB per DRI driver.
  * debian/rules:
  * debian/patches/116_use_shared_galliumcore.diff:
  * debian/libgl1-mesa-dri.install.in:
    - Link gallium DRI drivers against shared gallium routines to save CD

How about backporting it to Maverick? In a few days Firefox beta channel (which I use) moves to Fx 7 and Mesa versions up to 7.10.2 are blacklisted from OpenGL acceleration there, Mesa 7.10.3 is needed in Maverick!

Revision history for this message
Chris Halse Rogers (raof) wrote :

Maverick will not get 7.10.3; that's a bit more than a whole new major version over what's currently there, so it's not appropriate for a stable release update, and infrastructure like mesa is not appropriate for the backports process.

It's conceivable that natty could get 7.10.3 as an SRU, but mesa point upgrades generally include a bunch of non-bugfixes, which makes them hard to justify as a stable update.

I'm preparing an SRU upload to fix this particular bug in natty and maverick.

Closing the maverick task; as far as I'm aware, this is a natty-only regression.

Chris: During the LTSP hackfest we did some tests on Oneiric and it looked a lot like this bug. I did a test build adding the same patch to the Oneiric package and the build succeeded. I'm still waiting for someone to actually test the package though.

It indeed looks like this bug should be fixed in Oneiric but the symptoms are definitely still there and I can't really explain why the patch would still apply and build if it's already there.

Stéphane Graber (stgraber) wrote :

Hmm, the patch is indeed applied twice in my package, quite surprised it actually worked ;)

So Oneiric indeed contains the fix, just not quite sure why it didn't work in our tests...

Marking the Oneiric task as Invalid as the bug is already fixed there, will open another bug once we figure out what's broken.
