dilekssmb: what status on the x86-mm-fix you have in quantal?07:44
smbdileks, Upstream is aware and in some way agree it should get fixed but getting them actually comment on the patch is like convincing them to walk over hot coals...07:47
dileksyou need more lobby or to do more lobby work07:47

apwsmb, is that the one we committed recently ?07:49
smbapw, I assume so07:49
apwsmb, perhaps once it has been release in our kernle for a bit we might have more leverage07:49

brendandcking, do you remember do any of my fwts bugs need verification they were fixed?10:07
brendandcking, i have one affecting a HP DL385 G7 which appears to be, so i wanted to update any bugs that needed it10:08
brendandcking - i'm saying it's fixed because there's a failure of dmi_decode which happens in precise but not quantal10:09
ckingbrendand, lemme check the bug number.. I can't recall off the top of my head, I see quite a few in a month10:09
brendandcking, didn't we have a tag for ones from hw cert?10:10
ckingbrendand, 1021674 - fixed released in Q10:11
brendandcking, cool. all sorted then10:12
brendandcking, thanks!10:12

jjohansenso for CVE-2012-3400, the kernel side picked up oneiric and precise and its moved through to fix-released just fine.  for natty and lucid however the patches where backported and it doesn't seem to be moving through11:14
jjohansenthe patches are in the tree and seem to be properly annotated11:14

smartboyhwEr hi mates, anyway to add rt into the quantal Ubuntu kernel?11:30
jjohansensmartboyhw: ubuntu studio keeps a ppa with an rt kernel11:33
jjohansenhttps://help.ubuntu.com/community/UbuntuStudio/RealTimeKernel11:33
smartboyhwSure, I'm in Ubuntu Studio team:)11:34
smartboyhwSo then I wanna try compiling my own11:34
smartboyhwAlso that kernel has NOT been updated I think11:36
smartboyhwI mean PPA11:36
LetoThe2ndapplying to a stock kernel is probably considerably easier :)11:36
LetoThe2nds/stock/vanilla/11:36
jjohansensmartboyhw: ah11:36
jjohansenyep stock is likely easier to apply the patches too11:36
smartboyhwI know then, I want to try to compile it to a Ubuntu kernel instead of stock11:36
LetoThe2ndprobably the easiest is then to have git repo with two branches (ubuntu and rt) and then rebasing.11:37
smartboyhwOK11:37
LetoThe2ndgiven the possible amount of ubuntu patches, that is not for the faint at heart i'd guess.11:38

caribourtg: I meant it's not there as modules13:56
rtgcaribou, do you have the extras package ?13:57
smartboyhwIt just doesn't make at all13:57
apwsmartboyhw, as that is how i build it, so it clearly does work13:57
caribourtg: I'll check again after my call 13:57
apwsmartboyhw, ok then pastebin everything it says after the command13:57
rtgcaribou, I'm pretty sure its in linux-image-extras-*13:57
caribourtg: most likely not as I only downloaded the linux-image deb file13:57
rtgapw, he;s prolly missing build tools and/or deps13:58
apwrtg, probabally, but "doesn't work" isn't much to work with either way13:58

caribourtg: FYI it's in the linux-image-3.2.0-29-generic for Precise14:00
rtgcaribou, Precise doesn't have an extras package14:00
caribourtg: oh, I didn't know about this new stuff14:00

sforsheebjf, glad to hear it's better. It does look like the queues are getting backed up once in a while though ... I wonder why16:08
sforsheebjf, I've seen those illegal channel messages too, it's on my todo list to look into those16:08
sforsheeI've been seeing them without the new patch though16:08
bjfsforshee: i've not had to rfkill block/unblock it once. that's a nice change16:08
sforsheebjf, cool. Let's let it soak for a day or so, and if things are looking good we can get it into quantal at least16:09
bjfsforshee: ack16:09
sforsheebjf, the patch is Cc stable so it should filter into the stable releases, of course we could always pick it up sooner too16:10
bjfsforshee: would probably be nice for precise. 16:10
sforsheebjf, ack. Did you file a bug in launchpad for this issue?16:11

sforsheebjf, do you still think the patch at least improves the situation for you?16:39
bjfsforshee: yes, it is still up and running16:39
sforsheebjf, so you got the warning but the connection still seems to be working?16:39
bjfsforshee: yup16:40
sforsheebjf, okay. We probably ought to let Arend know about that then. Do you want to respond to him or should I?16:42
bjfsforshee: you've been the main contact, you can continue but cc me 16:42
bjfsforshee: i can respond directly if he has specific issues or questions16:43

jjohansenbjf: so you okay with dynamically building the tests17:43
jjohansenI don't think we have even discussed making a -tests package17:43
bjfjjohansen: building the tests, yes (i've fought that battle before) i just want to make sure we are testing the apparmor that gets installed and not one that the tests might build17:44
jjohansenbjf: yep its testing the installed version17:45
bjfjjohansen: i'm adding these to the std set of tests that we (the kernel team) run on all our kernels. when i'm happy with that, i'll push that to QA so they run the tests as well on all kernel packages.17:45
jjohansenbjf: or should be, I need to go through and verify that 'make tests' isn't triggering a local build in some of those places17:46
jjohansenbjf: sounds good, thanks17:46

jsalisburykamal, if you have a chance, can you take a look at bug 1041594 ?  It looks like a regression in alps track pads in 3.5.0-11.11.  I noticed some changes you made to cypress devices.18:00

jsalisburykamal, thanks!  I'm performing a bisect now, so I can let you know the findings of that.18:01
kamaljsalisbury: if its easier, you could just omit the changeset that I introduced for the new cypress driver and see if that fixes it.  do you have an ALPS to test with?  I do not.18:02
jsalisburykamal, I don't have an ALPS, but there are a few people that are willing to test in the bug report.  18:03

bjfrtg, the other page is the security team's page(s). jjohansen would know about that18:05

bjfsforshee: if i move the macbook up to my office, approx 8 ft from the ap and run the iperf test, it just scrolls and scrolls the the "No where to go" warning18:14
sforsheebjf, ack. How difficult is it for you to reproduce that state?18:19
bjfsforshee: trivial, it's hard to believe the developer hasn't seen this18:20
bjfsforshee: it starts up right away and just continuously scrolls18:20
bjfsforshee: it starts up right away when i start up iperf18:22
sforsheebjf, I'm going to try hacking some trace stuff into the driver to see if we can lock in on what triggers this problem. Hopefully by tomorrow morning I'll have something for you to test.18:23
sforsheebjf, I'm trying to reproduce it here but I can't seem to get it into the state that you're seeing18:24
bjfsforshee: wfm18:24
bjfsforshee: i have "iperf -s" running on the macbook and "iperf -c bradf-air -t 2000 -P -a -f b -i 2" on my desktop18:25
sforsheebjf, I'm doing iperf the other way, with the macbook as the client. I'll try it that way and see if my results are different.18:26
sforsheebjf, what's the -a option to iperf? I don't see any documentation for it.18:27

bjfsforshee: the -a is not necessary18:31
sforsheebjf, okay I'm getting the problem now. Maybe it has something to do with the channel; I wasn't using channel 3 previously.18:41
bjfsforshee: what channel were you using before?18:44
sforsheebjf, my 2.4 GHz AP had (oddly) settled on channel 2, the other is 5 GHz18:45
