Kanohi, when do you merge 2.6.24.6?11:11
maks_2.6.25.1 is the interesting target :D11:12
Kanoi mean for hardy11:13
Kanosecurity issues if you dont know11:13
Kanohttp://kernel.ubuntu.com/git?p=ubuntu/ubuntu-intrepid.git;a=commitdiff;h=c1838f1600cc7196363a23da1f76869600e17da111:14
Kanocan you show me where you see 0x1430, 0x4748 in upstream?11:14
amitkKano: check the kernel-team mailing list. smb posted a list of patches that are being considered from the stable series11:15
Kanowith a pure 2.6.25 it definitely does not work11:19
amitkKano: I am not sure, wait for rtg to come online or ask on the mailing list11:21
Kanowell i can compile your git code too, then i know it, but it did not work with standard 2.6.2511:21
Kanowill you revert the usb gpl only code?11:22
Kanoor do you just drop the usb modules from avm?11:27
=== gnomefre1k is now known as gnomefreak
rtgtjaalton: I just upload LRM -17.35 with a simple ABI bump.15:33
tjaaltonrtg: ok, cool15:39
gnomefreaktjaalton: you have a minute?15:58
gnomefreaktjaalton: is there a way for X to work around nvidia crashing X?15:58
rtgtjaalton: speaking of LRM, can you build a package for Intrepid? See http://ppa.launchpad.net/kernel-ppa/ubuntu for headers and stuff. I'm going to announce the Intrepid daily build pretty soon.16:01
amitkrtg: can new drivers be added to .1?16:02
amitkI am thinking specifically about ov51x-jpeg instead of the ov511 that we have in LUM16:03
amitk...even with the evil in-kernel jpeg16:05
amitkcompression16:05
tjaaltonrtg: no problem, I'll probably have time to do it later this evening16:08
tjaaltongnomefreak: dunno, how does it crash?16:08
gnomefreaktjaalton: scrolling on a page well 1 confirmed page and all crashes have 8600 or 8800 nvidia card with our drivers16:09
gnomefreaktjaalton: see bug 22496616:09
gnomefreaktjaalton: im wondering if xul is involed atm but i will ping asac about that later when i have something to base it on16:09
gnomefreaknoone can give me a backtrace just a couple of errors 16:10
tjaaltongnomefreak: I have a 8600GT.. :)16:11
gnomefreaktjaalton: can you please get me one lol16:12
tjaaltonthey are cheap ;)16:12
rtgamitk: perhaps. it is going to change current jpeg compression behavior in the general case?16:14
Kanortg: hi, does anybody want to add 2.6.26.6 to hardy kernel?16:17
laga2.6.26?16:18
tjaaltongnomefreak: yep, crashes here too16:18
rtgKano: only on a case by case basis.16:18
Kanoerr 2.6.24.616:18
rtgKano: I knew what yuou meant :)16:18
gnomefreaktjaalton: thought it would something with nvidia drivers have never been good with 6200 and up cards16:18
Kanocan you tell me how to merge that correctly? when i get an error that it cant be merged?16:18
rtgKano: well, you have to resolve the merge issues. git pretty much tells you what to do when the merge fails.16:19
Kanowell then the file hals =====  commented parts, you mean those i guess16:20
rtgKano: right. Start your search for '<<<', which is where the offending entries begin.16:21
Kanowell then i commited the change, i guess i made it right then16:21
Kanofor .5 there was only 1 wrong file16:22
Kanodid not try .6 yet16:22
tseliotgnomefreak: it doesn't crash here (Geforce 7300) however I'm using my own (customised) packages based on the lrm16:22
Kanortg: will you revert the usb gpl only patch?16:23
Kanofrom 2.6.2516:23
rtgKano: I do not know about this issue.16:24
Kanotry to compile avm usb modules16:24
Kanolike fwlan16:25
Kanoyou have got those in lrm16:25
Kanoand every other avm usb module16:25
rtgKano: I haven't the foggiest idea what you are talking about.  To my knowledge the Hardy LRM has no build issues.16:26
Kanortg: 2.6.25 is in your intrepid git16:26
rtgKano: for which we don yet have an LRM package.16:27
Kanowell does not matter, the drivers will not compile16:27
rtgtjaalton: is just now starting to think about LRM for Intrepid.16:27
Kanofor testing i added a patch for fglrx 2.6.25 (x64) and a revert patch for usb16:28
rtgKano: you're on your own there. Its gonna be July before I get really interested in Intrepid problems.16:31
maks_using fglrx is stupid enough16:32
tseliotmaks_: no flame-baits, please16:33
Kanortg: also it seems that the dmraid in lum does not work, at least Rabiddog has problems16:47
Kanothe module is there but it is not recognized16:48
rtgKano: which lum? Hardy or Intrepid?16:49
Kanohardy16:49
Kanoi would like to test it myself, but i only have got 2 similar drives, not 316:49
mdomschrtg: http://lkml.org/lkml/2008/5/2/20518:03
mdomschwill be needed for the server kernel18:03
rtgmdomsch: backported for Hardy I assume?18:04
mdomschrtg, yeah18:04
mdomschsoon as ingo pushes it to linus for .26 and -stable picks it up18:05
rtgmdomsch: I'm working on SRUs, so this is a good time to git 'er done.18:05
mdomschI'm filing a bug in LP now18:06
rtgmdomsch: I'll watch the .7 stable updates for this (when they appear).18:06
mdomschto track18:06
mdomschhmm, I read on lwn that there wouldn't be .718:06
mdomschor did I misread?18:06
rtgmdomsch: oh, thats right. 18:06
rtgmdomsch: well, even if it goes into 25.y it ought to work.18:07
rtgmdomsch: lemme know the LP number and I'll assign myself to it so I don't forget.18:07
SEJeffIs CONFIG_VERSION_SIGNATURE an ubuntu specific config option?18:09
rtgSEJeff: yeah, I think so.18:09
SEJeffrtg, Ok so in Re: the btrfs failing miserably on ubuntu thread... could we do like SUSE and use CONFIG_VERSION_SIGNATURE instead of CONFIG_SUSE?18:10
rtgSEJeff: that doesn't mean the AA patches exist. Intrepid won't get them for awhile. I still think the CONFIG search is the best approach.18:11
mdomschrtg, LP 22581118:12
SEJeffOk so how about an explicit test for the hardy kernel version? If it is a user built kernel, they will know enough to apply a patch manually?18:12
rtgSEJeff: I don't spend a lot of time supporting user built kernels. Its not that I don't care, I just don't have time. So, if they know enough to apply the patches, then more power to them. Otherwise, they are on their own.18:14
SEJeffrtg, something like: http://pastebin.com/m64b6a4dc18:14
SEJeffrtg, That was my point. You are agreeing with me. If it is a stock ubuntu hardy kernel, that would catch it. A stock hardy kernel has apparmor applied18:15
rtgSEJeff: that definitely works for Hardy. 18:15
SEJeffOk well then I'll respond to that thread, Chris can put that in btrfs, and we can happily test the next get linux filesystem. Thanks18:16
rtgSEJeff: np.18:16
SEJeffrtg, One last thing. Would it be a better idea to do a version check for each official ubuntu kernel with apparmor?18:18
rtgSEJeff: I can't remember when the AA patches appeared. with Feisty? You know, I'm still not sure why CONFIG_SECURITY_APPARMOR isn't sufficient? If the AA patches have been applied, then the Ubuntu kernel won't compile unless CONFIG_SECURITY_APPARMOR=y. So, I can guarantee the AA code is compiled.18:22
SEJeffIs that because it is such an invasive patch and doesn't ifdef everything out?18:23
rtgSEJeff: pretty much. I think remove_suid() is a good example. The prototype is changed, but not guarded by an AA ifdef.18:24
rtgSEJeff: it would take long to verify that for sure.18:25
rtgs/wwould/wouldn't/18:25
SEJeffrtg, Alright, I'll do a few compile tests with CONFIG_SECURITY_APPARMOR disabled on hardy kernels18:25
SEJeffrtg, Thanks18:25
rtgSEJeff: ok, let me know if I'm completely wrong.18:25
SEJeffrtg, compile test without APPARMOR builds, tried it twice. make -j8 is a great thing18:52
SEJeffIt gives some nasty warnings so I'm not sure how well it would work18:52
Rabiddogre: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/22049318:56
Rabiddogdoes anyone know what changed from kernel 2.6.24-12 to 2.6.24-16 that affected dmraid?18:56
rtgSEJeff: drat. All I can say is that Ubuntu isn't gonna apply the AA patches without also compiling them. I think its safe to assume CONFIG_SECURITY_APPARMOR will always be 'y'19:00
SEJeffAnd upstream will likely also agree with that. It is a safe assumption to assume the user is smart if the case is otherwise19:00
rtgSEJeff: The user best be smart :)19:01
RabiddogThe following error "ERROR: device-mapper target type "raid45" not in kernel" is occuring19:01
smbRabiddog: Might be just a naming problem19:02
calcrtg: do you recall which bug number is about the key stuck scheduler related bug?19:02
calci'm seeing 188226 but that doesn't appear to be the one i saw before19:03
smbRabiddog: I just got a PPA ready for testing https://launchpad.net/~stefan-bader-canonical/+archive19:03
Rabiddogsmb, any idea how to fix it? my raid array is no longer recognized, in gutsy and buddy of mine compiled a new kernel for me19:03
Rabiddogk looking at that19:03
RabiddogPPA stand for what?19:04
smbRabiddog: Personal Package Archive19:04
RabiddogI see...does it have a fix for that in it?19:04
smbRabiddog: IOW someplace to put stuff to try. I hope so. MAinly I just made sure the module is named in a more standard way19:05
rtgcalc: I think it was this one: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=commit;h=4b7c68904bf9ada8c4770ce5927e8ec71769ed9219:05
RabiddogWell I'm willing to test, I'll add those sources to apt19:05
* Rabiddog flips screens19:05
calcrtg: yea :)19:05
calcbug 218516 was the one i saw before :)19:06
smbRabiddog: Great. Let me know whether this helps19:06
calca user was mentioning they were bitten by what sounds like that bug19:06
Rabiddoggimme a few gotta manually copy the sources19:06
calcrtg: is it fixed in hardy-proposed/hardy-updates yet?19:06
rtgcalc: its an SRU in -proposed. I'll upload -meta in a bit (which should complete the whole ABI bump process)19:06
calcrtg: ok19:07

Rabiddogrebooting the box now :)19:19
RabiddogThe following error "ERROR: device-mapper target type "raid45" not in kernel" is still occuring, smb 19:21
Rabiddoghmm however19:21
smbRabiddog: Thats bad19:21
smbRabiddog: does lsmod show a dm-raid45 or dm_raid4519:22
smb?19:22
mdomschrtg: LP 225811 if you'd take it please19:22
Rabiddogsec...it gave the error but my hdd array loaded19:23
Rabiddogchecking lsmod19:23
smbRabiddog: likewise "dmsetup targets" should list it as well. If yes, maybe the msg is just an initial warning before loading the module19:24
Rabiddogshows dm_raid4519:28
Rabiddog is that bad or good, smb 19:29
smbRabiddog: I would count is as good. If dmsetup shows dmraid45 as target as well, well then it should work19:30
Rabiddogsec checking that19:30
smbRabiddog: And one final thing: "dmsetup table" should list something with dmraid45 as well (if that is used)19:31
Rabiddogdmsetup targets shows just "raid45"19:32
Rabiddograid45 as well19:32
Rabiddogfor tables19:32
smbRabiddog: Not linear? 19:32
Rabiddoghuh19:32
smbRabiddog: linear is a built in target of device-mapper. Should normally be there19:33
Rabiddogsec19:33
Rabiddogyep its there first line19:34
Rabiddogforgive me I may have compiled kernels but I'm still a bit of a noob :)19:34
smbRabiddog: So that looks good setup wise.  No prob. 19:34
smbRabiddog: So before, there were the messages and the array was not created and now we still have the message but it is19:35
Rabiddogok.... now this adventure broke my nvidia drivers for sum reason....lol19:35
Rabiddogsmb, k19:36
Rabiddogthanx...is that all that needs testing smb?19:36
smbRabiddog: Hm, strange. I guess one thing. I would put some updates to bud 22ß403. Maybe you could add some coments from your test19:38

smbRabiddog: Ok, thanks. Hopefully this helps others as well. And then maybe that qualifies as simple quirk... Let's see20:55
Rabiddogk20:56
Kanobtw. the dmraid should be patched too20:58
Kanoin 3 positions20:59
Kanoinit script, then the module should be added to initramfs, then it should be loaded in initramfs20:59
Rabiddoglooks at smb21:02
smbKano: That would be a different story (domain). 21:02
Rabiddogheh, I forgot I still have have modprobe -Q dm-raid4-5 in my initramfs script21:04
smbRabiddog: That was the old name. Should not do anything now21:05

Rabiddogthanx for your help smb21:14
smbRabiddog: ur welcome :)21:14
Rabiddogand now u know it works except for the quirk21:15
smbRabiddog: Yup. Thanks for trying21:18
Kanobtw. the dm name is correct21:21
Kanono need to change that21:21
Kanodm-raid4-5 is the name from the official patch too21:22
smbKano: But that was the only change I made between not working and working.21:22
Kanoit never had a differnet name..21:23
smbKano: Most other modules keep their names close to the target name. So autoload works. 21:23
Kanowell you need to put it in the initrd anyway 21:24
Kanoor you need to use another hd for booting21:24
smbKano: sure. Though I don't see this likely for Hardy after it is now released.21:25
Kanomaybe fast enough for a service relase21:27
Kanoas you want to support it serveral years ;)21:27
* Rabiddog eyes the gnome Ui windows bug that cropping up21:27
Kanobtw. the lum for intrepid does not compile, missing unionfs include21:28
* Rabiddog eyes the hal mod and its bugs21:28
Kanocan i copy the aufs folder to the hardy lum?21:29
Rabiddogkano whats is lum btw?21:32
Kanoalso it was 100% wrong to drop my patch for the guitar, it does not work with your intrepid git21:34
Kanonothing in upstream21:34
Kanoat least not the guitar21:35
pwnguinguitar?22:05
pwnguinin kernel?22:05

Kanothats my patch22:06
pwnguinthat seems like a simple patch to pass upstream22:06
Kanoand the guitar does not work with 2.6.2522:06
pwnguin2.6.25 would work with the extra identifier though?22:07
Kanodid not try yet, i only added some other patches to fix build problems22:08
Kanotested it before with the debian trunk kernel22:08
pwnguinI'm just saying if it works, you might as well get it included in kernel.org22:08
pwnguinits The Right Thing To Do22:09
Kanowell i made it for 2.6.2422:09
Kanoand there it works22:09
pwnguinits a two line patch that almost certainly didn't change22:09
Kanoit is cool to play frets on fire with that guitar22:10
pwnguinsure22:10
pwnguinbut wherever possible I think the kernel team should be providing changes upstream as well22:11
pwnguinand this is... very possible I think22:11
Kanowhy is alsaconf removed in ubuntu?22:13

Kanocrimsun: well i need that22:15
crimsunKano: the correct method is to fix the ISA drivers.22:16
Kanocrimsun: i need it to unload drivers when they have been loaded in wrong order22:16
crimsunKano: err...22:16
crimsunyou should never have to use alsaconf to reorder indices22:17
Kanoso what do you use22:17
crimsunyou can either use the index module parameter for each ALSA driver, or you can use the slots parameter for snd.ko (requires alsa-kernel >=1.0.16)22:18
Kanooptions snd-emu10k1 index=022:18
crimsunyou'd place them in a modprobe conffile, e.g., options snd slots=snd-usb-audio,snd-emu10k1,snd-hda-intel22:18
Kanowhen this is set it still loads the other as 022:19
crimsunthat's why I recommend using snd.ko's slots parameter instead of each driver's index parameter.22:19
Kanobut as hotfix alsaconf is really good to use22:20
crimsunwith slots, index 0 is reserved for snd-usb-audio, index 1 for snd-emu10k1, index 2 for snd-hda-intel22:20
crimsunthere's no real reason to use alsaconf for that.  One can script the above sequence for an arbitrary set.22:21
Kanohow about putting it in an extra package for those who really want it?22:21
crimsunI would strongly recommend against doing so, but I certainly won't stand in the way of other core-devs changing debian/rules.22:22
crimsunblah, I'll just write a script to do what you need22:23
crimsun(and stash it in alsa-utils)22:23
Rabiddoglol22:24
Rabiddogcrimsun, I saw your tip on the bug report for me I'll try it later22:25
