SRU Impact/Description
Fixes frequent xorg segv's for radeon r300/r400 users introduced as a "severe regression since jaunty".
The patch prevents memory from being used after it's free'd and it has been confirmed
to solve two upstream bugs (the linked one plus another bug that Michel Dänzer mentions in the upstream bug report).
Examples of hardware that is known to be affected:
01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV380 [Radeon
X600 (PCIE)] [1002:5b62]
01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV350 AP [Radeon
9600] [1002:4150]
TESTCASE
1. boot jaunty on the affected hardware
2. install "compizconfig-settings-manager"
3. activate the "ring switcher" plugin (launch settings manager from system::preferences) and make sure it's Initiate keybinding is SUPER+TAB
4. hold down SUPER-TAB for 2-3 seconds so that the windows swirl around full speed.
5. SEGV in xorg, back to gdm.
(there are very likely several other compiz operations/transformations that
trigger the crash but the ring switcher seems to be the most reliable repro.
For example in the upstream bug report one uses reported he had a crash that
happened when he was "constantly resizing a gnome-terminal" and that this crash
stopped happening when he installed the testing DEB that held the patch in this SRU).
TODO FOR SRU
Not subscribing the SRU team yet because this patch is not in karmic yet.
I've upgraded my ATI machine to create and test a karmic debdiff but right now
compiz refuses to install properly due to dependency problems / broken package.

[Impact]
Fixes frequent xorg segv's for radeon r300/r400 users introduced as a "severe regression since jaunty".
The patch prevents memory from being used after it's free'd and it has been confirmed
to solve two upstream bugs (the linked one plus another bug that Michel Dänzer mentions in the upstream bug report).
Examples of hardware that is known to be affected:
01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV380 [Radeon
X600 (PCIE)] [1002:5b62]
01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV350 AP [Radeon
9600] [1002:4150]
[Karmic - Development]
This same patch has been uploaded to Karmic. Also, we will soon be updating to a newer version of mesa which already includes this change.
[Jaunty - Stable]
This patch, a cherrypick from the upstream release, is proposed for jaunty:
http://launchpadlibrarian.net/26309613/lp368049_jaunty_proposed.debdiff
[Testcase]
1. boot jaunty on the affected hardware
2. install "compizconfig-settings-manager"
3. activate the "ring switcher" plugin (launch settings manager from system::preferences) and make sure it's Initiate keybinding is SUPER+TAB
4. hold down SUPER-TAB for 2-3 seconds so that the windows swirl around full speed.
5. SEGV in xorg, back to gdm.
(there are very likely several other compiz operations/transformations that
trigger the crash but the ring switcher seems to be the most reliable repro.
For example in the upstream bug report one uses reported he had a crash that
happened when he was "constantly resizing a gnome-terminal" and that this crash
stopped happening when he installed the testing DEB that held the patch in this SRU).
[Regression Potential]
The scope of the patch is limited by the fact that the code changes are against the r300* files.
The patch changes the handler of a texstate pointer; like any change involving pointers this carries some regression risk, but probably no worse than the existing bug. In any case, this patch should receive extra testing by r300/r400 users before deployment.
TODO FOR SRU
Not subscribing the SRU team yet because this patch is not in karmic yet.
I've upgraded my ATI machine to create and test a karmic debdiff but right now
compiz refuses to install properly due to dependency problems / broken package.

[Impact]
Fixes frequent xorg segv's for radeon r300/r400 users introduced as a "severe regression since jaunty".
The patch prevents memory from being used after it's free'd and it has been confirmed
to solve two upstream bugs (the linked one plus another bug that Michel Dänzer mentions in the upstream bug report).
Examples of hardware that is known to be affected:
01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV380 [Radeon
X600 (PCIE)] [1002:5b62]
01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV350 AP [Radeon
9600] [1002:4150]
[Karmic - Development]
This same patch has been uploaded to Karmic. Also, we will soon be updating to a newer version of mesa which already includes this change.
[Jaunty - Stable]
This patch, a cherrypick from the upstream release, is proposed for jaunty:
http://launchpadlibrarian.net/26309613/lp368049_jaunty_proposed.debdiff
[Testcase]
1. boot jaunty on the affected hardware
2. install "compizconfig-settings-manager"
3. activate the "ring switcher" plugin (launch settings manager from system::preferences) and make sure it's Initiate keybinding is SUPER+TAB
4. hold down SUPER-TAB for 2-3 seconds so that the windows swirl around full speed.
5. SEGV in xorg, back to gdm.
(there are very likely several other compiz operations/transformations that
trigger the crash but the ring switcher seems to be the most reliable repro.
For example in the upstream bug report one uses reported he had a crash that
happened when he was "constantly resizing a gnome-terminal" and that this crash
stopped happening when he installed the testing DEB that held the patch in this SRU).
[Regression Potential]
The scope of the patch is limited by the fact that the code changes are against the r300* files.
The patch changes the handler of a texstate pointer; like any change involving pointers this carries some regression risk, but probably no worse than the existing bug. In any case, this patch should receive extra testing by r300/r400 users before deployment.
TODO FOR SRU
Not subscribing the SRU team yet because this patch is not in karmic yet.
I've upgraded my ATI machine to create and test a karmic debdiff but right now
compiz refuses to install properly due to dependency problems / broken package.
