| hallyn | apw: say, i'm hoping to do a lxc irc meeting in a few weeks to discuss direction with userns. The first 20 minutes would be an overview. Would you or anyone from kernel team want to listen in on that part? | 02:55 |

| arges | found an interesting kernel bug. plugging and unplugging a usb headset causes a panic on 3.2 | 14:40 |
| jsalisbury | arges, can you reproduce it easily? | 14:44 |
| arges | jsalisbury: yea i'm doing that now... getting a backtrace and if we are really lucky ill have a vmcore as well | 14:45 |
| jsalisbury | arges, cool. I recall a similar bug reported in the past few days. I don't remember off had if it was for Precise. I'll go an look | 14:46 |
| jsalisbury | arges, it could be bug 1097396 that you are hitting. | 14:48 |
| ubot2` | Launchpad bug 1097396 in linux (Ubuntu) "Unplugging USB Headset causes Kernel Panic" [High,Incomplete] https://launchpad.net/bugs/1097396 | 14:48 |
| arges | jsalisbury: easily reproducible at this point.. tempted to try my raring laptop. but don't want to loose IRC | 14:48 |
| arges | jsalisbury: cool looks like this is also precise | 14:49 |
| jsalisbury | arges, yeah, I started a bisect, but waiting for testing feedback. | 14:49 |
| jsalisbury | arges, can you try the latest 3.2 kernel? It's 3.2.37 now | 14:49 |
| arges | jsalisbury: let me compare notes | 14:49 |
| arges | jsalisbury: to see if i'm hitting the same thing | 14:50 |
| jsalisbury | arges, that bug is fixed in mainline | 14:50 |
| jsalisbury | arges, and raring | 14:50 |
| arges | jsalisbury: we have a winner snd_complete_urb | 14:52 |
| arges | jsalisbury: same backtrace here | 14:52 |
| jsalisbury | arges, cool | 14:52 |
| arges | downloading and testing | 14:52 |
| jsalisbury | arges, yeah, it could be fixed in .37 since it's fixed in the 3.7 and 3.8 kernels. | 14:53 |
| arges | jsalisbury: ok tried that kernel still paniced | 15:00 |
| jsalisbury | arges, ok. Maybe a reverse bisect is needed | 15:01 |
| arges | hmm now kdump wants to work :) | 15:01 |
| jsalisbury | heh | 15:02 |
| sforshee | cking, does the firmware on your x230 have an object named BRTW in the EC namespace that is returned by _BCL? | 15:02 |
| jsalisbury | arges, i haven't done any research upstream on that bug yet. That's another approach in addition to a reverse bisect | 15:03 |
| arges | jsalisbury: if you want to start the bisect, i could look at the backtrace a bit and see if I can get anything by looking and blaming | 15:04 |
| jsalisbury | arges, I believe v3.7 final did not have the bug. Maybe try v3.6 final? | 15:04 |
| arges | jsalisbury: ok that's a bit easier... machine is still taking a dump | 15:04 |
| arges | that sounds bad | 15:04 |
| jsalisbury | arges, sure. I can't reproduce the bug here, but I'll update bug 1097396 and work with Tony | 15:05 |
| ubot2` | Launchpad bug 1097396 in linux (Ubuntu Precise) "Unplugging USB Headset causes Kernel Panic" [High,Triaged] https://launchpad.net/bugs/1097396 | 15:05 |
| arges | jsalisbury:well i'lll test 3.6 first | 15:07 |
| jsalisbury | arges, cool | 15:07 |
| arges | jsalisbury: and i can do the bisect | 15:07 |
| jsalisbury | arges, great. can you also update that bug as you go? | 15:07 |
| arges | jsalisbury: yup | 15:08 |
| jsalisbury | arges, thanks! | 15:08 |

| hallyn | say, I'm getting a build error in libvirt due to include/linux/if_bridge.h using struct in6_addr without it being defined. | 18:43 |
| hallyn | can that be considered a bug in the header? | 18:43 |
| hallyn | or is it reasonable to say all userspace using that now has to #include <netinet/in.h> ? | 18:43 |
| doc___ | Kernel question: I'm trying to write an app that talks to USB cameras. Should I use /dev, /proc or sysfs? | 18:43 |
| hallyn | it was added on dec 6 as part of commit "bridge: export multicast database via netlink" | 18:45 |
| apw | hallyn, well if in4_addr is defined without additional headers and in6_addr not, that sounds like a bug | 19:55 |
| * rtg -> EOD | 19:56 | |
| hallyn | apw: i suspect in4_addr is also not defined | 19:56 |
| hallyn | apw: but that isn't used in if_bridge itself | 19:56 |
| apw | oh hmmm, i wonder why in6_addr is used | 19:56 |
| hallyn | apw: see https://www.redhat.com/archives/libvir-list/2013-January/msg00957.html. it was used as of a commit on dec 7 | 19:57 |
| hallyn | oh, i see. i thought the thread on netdev had died, but i guess it's more recent than i thought, so still on-going | 19:58 |
| apw | hallyn, well that doesn't really resolve ... but hopfully will | 20:01 |
| hallyn | apw: right. hopefully. meanwhile i'll work around it in libvirt (using the upstream patch) but i expect more build breakages in raring | 20:03 |
