ademmerkamal: do you know, when you could submit your patch to the upstream kernel?09:46
apwademmer, kamal is normally awake much later in the day10:06

cooloneyapw: one quick question, when will our M kernel be freezed?10:59
cooloneywe might got some big patches for ti-omap4 in Sep11:00
apw*might* ?11:00
cooloneyyeah, their montly release11:00
cooloneyapw: September 16th, right? for kernel freeze11:01
apwcooloney, yes 16th is the cut-off, though our freeze date will likely be 9th or 10th as we have to prepare them11:02
cooloneyapw: thx, i got it. so if we got about 200 patches before Sep 9th and we prepared the new ti-omap4 branch11:03
apwupload them, wait for them to build, fix them, repeat11:03
cooloneyit is ok for mergeing right?11:03
apwis what ok for merging where?11:05
apwcooloney, ^^ ?11:06
cooloneyoh, merging into Maverick ti-omap4 tree. 11:08
cooloneyi am afraid that they will get us a big volumn patches just at our kernel freeze time.11:09
apwas long as its tested before then i guess its ok, but its the mobile team who have to test them11:09
cooloneyor close to11:09
cooloneyyeah, thx. we will work on that. 11:09
apwit would be better to get stuff much earler as you are making all the testing done at A3 and Beta pointless11:10
cooloneyapw: yeah, i am trying to push that. 11:10
cooloneybut bascially, their relese at the first half part of every month11:11
apwso how many patches did we get this month11:11
cooloneyi was told there will be 200 at least for our .34 kernel11:12
apwwe need to get buy in from mobile that they are ok with it changing things that late i guess11:12
cooloneybut just one month later, we will move to .35 ti-omap4 kernel11:12
cooloneyso i don't wanna merge too many things,11:13
apwhave we had the july patches yet?11:13
cooloneyno11:13
apwso we're not likely to get them in time are we11:13
cooloneywe got 200 more patches in July11:13
apwwe 'have got' or 'will get'11:13
cooloneywe are discussing these. 11:14
cooloneyactually they have 900 patches in July relese11:14
apwbut have they released the july release to us yet ?11:14
cooloneyand sebjan is helping to pick up some for our Ubuntu usage11:14
cooloneyapw: no, they released internally 11:15
cooloneybut sebjan is helping to pick up some and release for us11:15
apwso the likelyhood is that the august from is not going to arrive in time then11:15
apwaugust patch drop11:16
cooloneyi was told it will be 20011:16
cooloneynext month, August they will release a new branch based on .3511:16
cooloneywe have to redo lots of work 11:16
apwright ... and then the september drop is the one you care about11:16
cooloneyand replace our current .34 branch11:16
cooloneyyeah, 11:17
cooloneycorrect11:17
apwand that isn't likely to be done in time 11:17
cooloneybecause september drop is similar to this month11:17
cooloneyi think so11:17
apwas they haven't got the july one out before the 16th11:17
cooloneyright.11:17
apwif it doesn't make the 10th they'll have to wait till after release i suspect11:17
cooloneyexactly,11:18
apwand you can fight the sru team to get it through :)11:18
cooloneylol,11:18
cooloneyjust wanna let them know the tight schedule11:19
apwyep tell them the 9th11:19
cooloneyyeah, already told sebjan about that. 11:19
apwthat gives us a week to integrate and build them before we can no longer upload11:19
cooloneybut he is not sure about that11:19
cooloneyyeah, that will be perfect.11:20
apwthen they miss the release11:20
apwtime waits for no man11:20

penguin42if Apparmor loads a profile in Complain mode (apparmor_parser -Cr) should it change the behaviour of the application at all?14:31
* penguin42 has a chromium profile that breaks it even in complain14:31
apw_Jjohansen ^^14:38
jdstrandpenguin42: it should not affect it, but the '-r' reloads it and that is not always what you want. I suggest doing 'apparmor_parser -R...' followed by 'apparmor_parser -Ca'14:39
jdstrandpenguin42: that is a full remove followed by add. you will have to restart chromium though14:40
penguin42jdstrand: Hmm, closer but not quite - I don't get any fonts with it like that14:41
penguin42but they reappear with -R14:42
jdstrandthat should not be happening14:42
jdstrandpenguin42: what does aa-status show?14:42
penguin42jdstrand: Let me paste bin it14:44
penguin42jdstrand: http://paste.ubuntu.com/464540/14:45
penguin42jdstrand: I get the feeling chromium has an odd way of doing its sandboxes which is where the null-numbers come from14:46
jdstrandpenguin42: the null profiles do result from the sandboxes, but they are in complain mode anyway, so it shouldn't matter14:51
jdstrandpenguin42: does dmesg provide any output?14:52
jdstrand(on the denial)14:52
penguin42it gives a few moans; I'll pastebin them14:55
penguin42jdstrand: http://paste.ubuntu.com/464546/14:58
penguin42jdstrand: This is on 2.6.35-8, on Lucid I used to get a lot more moaning in complain mode, but it worked14:58
penguin42mind you, there were some moans that I never got to the bottom why they were there14:59
penguin42jdstrand: http://www.treblig.org/debug/usr.lib.chromium-browser.chromium-browser   is the profile15:00
jdstrandpenguin42: well, profiling with complain mode is different than profiling in enforcing. eg, in enforcing an actual denial will cause a different code path than a complain which didn't deny15:02
jdstrandpenguin42: anyhoo, I think we need jj to take a look. I don't see anything that should make chromium not work in complain mode15:02
penguin42jdstrand: OK, thanks15:03

bjf[afk]chazn85, it's used by the kernel team, just ignore it22:21
chazn85ok will do, as an aspiring member currently being tutored by JFo was just curious to what it was22:25
jjohansenchazn85: kj is kernel janitor22:25
jjohansenbasically its a tag used by the arsenal kernel janitor scripts22:26

jjohansenyep, to really know what it does you need to look in the arsenal scripts22:28
bjf[afk]chazn85, the scripts add it and then check for it so the same bug isn't processed multiple times for the same reasons22:29
chazn85thanks guys, all part of the learning curve, ill ignore them for the time being 22:33
