hggdhkees, sconklin: please see bug 810807 on the Maverick backport to lucid00:08
ubot2Launchpad bug 810807 in linux-lts-backport-natty "kernel-test-security multiple errors on backported Maverick kernel" [Undecided,New] https://launchpad.net/bugs/81080700:08
keesohsix: yeah, it moved to /var/log/syslog iirc02:30
keeshggdh: oh, er, yeah. they are inverted tests. it's checking the release not the kernel02:31
keeshggdh: e.g. CONFIG_DEBUG_SET_MODULE_RONX is enabled (a good thing) when it wasn't expecting it for lucid.02:32
keeshggdh: let me work on that and get the tests updated. that's going to take a bit of work...02:32
paultagapw: poke, if you're about02:41
paultagapw: my desktop dropped back into the failure mode. I was able to ssh in, and check up on it. Turns out compiz is taking up 100% of one core, and xorg is taking up 100% of another.02:42
paultagapw: is this what happens with the vsync bug?02:43
paultagprocess (compiz) is stuck in state "Rl"02:44
RAOFIf you're thinking of “disconnecting outputs can cause vblank events to be missed”, then, no, it's not that bug.02:45
paultagAh, thanks RAOF. He suggested that as what might be going on with my box.02:46
paultaghumm, it looks like compiz is just oustandingly borked02:47
RAOFThe symptom of that bug is that compiz is not taking up CPU because it's waiting in the kernel for a vblank event that will never arrive.  It can do that quite efficiently :)02:47
paultagRAOF: gotcha. Not kernelspace at all :)02:47
paultagRAOF: cheers, thanks for the help, I'm outa here!02:48
hggdhkees: cool, no problem02:56
blisskees: better start brainstorming on how to give users the option of opting in to mainline PAX_USERCOPY, which has a 6-9% performance hit on some benchmarks :-/03:00
blissvasiliy is making some good headway i think03:00
keesbliss: yeah, been watching that. :)03:27

awilkins#776964 : compiling my own kernel again. Frowny face.   ;-P08:49
hggdhgood morning to all. If I may ask, why isn't there a Natty backport for server-i386?12:22
smbhggdh, if you mean a flavour -server? That would be generic-pae...12:39
ogasawaraawilkins: just posted a comment to your bug regarding status of the patch13:04
awilkinsOOh, ta13:04
ogasawaraawilkins: it took us a little longer to get the first natty update out the door due to regressions, but your patch should land in the next round of updates.13:05
awilkinsIt's ok, my local build has finished... discovered a workaround in the process of patching it also, so wasn't a showstopper, used HDAanalyzer to tweak the pin config parameter so I could use sound card today13:07
awilkinsBut at least now I won't have to build another kernel13:08
ogasawarasconklin: do you guys keep a list of bugs to shove in the changelog when you close a release so it gets auto closed by the janitor when you upload?  or would you prefer I just add the BugLink to the commit and re-push to the repo.13:10
ogasawarare: bug 77696413:11
ubot2Launchpad bug 776964 in linux "p5n32e-plus HDA Nvidia AD1988B microphone input not working" [Low,Fix committed] https://launchpad.net/bugs/77696413:11
sconklinogasawara: we don't actually have any defined process for getting bug numbers into the changelog if they don't get put into the SRU request. This is mostly because we don't have a good way to associate fixes with existing bugs. This is a problem that needs solving. We usually just leave it to the reporters to close them.13:40
sconklinogasawara: but the worst part of all that is that reporters don't get notified when something is in -proposed that might fix their issue13:40
ogasawarasconklin: right.  do the scripts which shove a comment into the bug regarding testing, I assume it parses the changelog?13:42
sconklinactually, no. I think It only hits bugs which are tagged as needing verification. And this isn't all that well scripted and requires manual work. In the case of upstream patches we get via a longterm release, there's only one bug open for all those patches, and we don't associate other bugs like the one you linked13:44
ogasawarasconklin: ah13:45
sconklinThis whole area is probably the next big area we need to focus on13:45
sconklinWe had a similar problem determining when upstream commits close CVEs, but the security team handles that now afaik13:46
ogasawaraseeing as this patch came to us through stable, so I supposed I could mark it as a duplicate of the master bug which covered the pull from stable13:46
sconklinthat will get it closed, it won't result in messages to the bug. But - good idea13:48
sconklinand that's a really good solution until we do something better13:48

hertonhmm ok, yeah I remember we had to add some extra files to commit already, we will note this ones as well14:50
hertonperhaps the script could do git add on them automatically14:50
tgardnerherton, it does automatically add files that are under git control, but doesn't typically add new files. this is a one time thing (for now)14:51
hertonyep, it could do the add of required new files, if possible (don't remember the exact details, I think it's possible to do)14:55
ogasawaraanyone else notice launchpad throwing away their comment if setting status and importance at the same time?14:58
ckingmore pain, less gain15:00
tgardnerherton, there really shouldn't be that much churn with the backports from released kernels, so I'm not sure its worth the complexity in the update script.15:01
johanbrcnd: I read you've developed some clickpad patches. In your opinion, what's the proper way to support clickpads (bug 582809) ?15:04

keesherton: thanks! I don't know how I managed to click that :( fixing16:10
cndjohanbr, it's been a while since I've looked into clickpads in detail16:11
cndoff the top of my head I think there really doesn't need to be any extra kernel patches to get the functionality people want16:11
cndit can more easily be handled in xserver-xorg-input-synaptics16:11
johanbrright16:11
cndbut that's really off the top of my head16:12
cndso don't hold me to it if I'm forgetting an important detail :)16:12
cndit appears anything to do with synaptics and multitouch is a big pita16:13
johanbrfor the synaptics driver, something like https://patchwork.kernel.org/patch/92435/ I guess16:13
johanbrI think I'll try building a synaptics driver with that patch for testing, then bug the X guys16:14
johanbrthank you!16:14
cndjohanbr, that kernel patch has been thrown around a lot16:16
cndI think there's good reason why it's not in the upstream kernel tree by now16:16
cndbut I couldn't tell you what that reason was16:16
cndI can only guess that people thought it was better handled in userspace16:16
johanbrsorry, wrong URL... I meant http://patchwork.freedesktop.org/patch/3160/16:17

keeshggdh: okay, it's a really massive change, but I've tested on all my KVM instances and on the natty backport kernel. I haven't retested on ARM or weird stuff (xen, etc) so there might still be some subtle fixes needed, but qrt rev 1347 should work for the backport kernel now19:48
hggdhkees: thanks, I will update the tarball and try again (including xen)19:49
keeshggdh: thanks! let me know if anything looks weird. I think I've got the nastier of the corner-cases already (mostly relating to kptr_restrict and its change)19:52
hggdhkees: certainly will ;-) as an aside, all 8 failures were indeed due to checking on ubuntu version?19:52
