he's known to be busy === pkl_ [n=phillip@unaffiliated/pkl/x-764568] has joined #ubuntu-meeting [06:02] Ok, this is the start of the Kernel Team meeting [06:02] agenda hasn't been updated, but it's quite simple [06:03] beta freeze looming, and we are handling as many bugs as possible to make beta release [06:03] The most major issue right now is the unionfs breakage that pkl is working [06:03] pkl_: Can you give a quick one or two lines about your status so you can get back to things? [06:04] I have identified two serious bugs in Unionfs that the liveCD is hitting [06:05] two...are they both causing the same symptom we've been seeing about refcount backtrace? [06:05] pkl_, i see a lot issues in ltsp as well recently ... if you need any logs or so, just ask .. [06:06] The first relates to the BUG_ON in fanout.h, called by unionfs_flush (file close). This is a race condition, not with the actual dentry being closed, but with the parent dentry going bad, with no branches (which is wrong). [06:07] I believe the problem is related to rsyncing of the parent unionfs directory with the lower filesystems (i.e. ro squashfs, and rw tmpfs). [06:07] The good thing is whilst I've not discovered the underlying problem, it is easily worked around. [06:08] is that a kernel work around, or a userspace one? [06:09] kernel unionfs workaround - the only reason why the parent branches are being examined is to resync the mtime. A simple fix is to check there _are_ branches on the parent dentry, and to skip the mtime resync if there aren't. This "fixes" the BUG_ON in my tests. [06:10] It is a workaround that will work while the underlying race is identified. [06:11] The second bug is the kernel oops in inode.c (unionfs_open). [06:11] ok, that'll make everyone happy happy [06:11] pkl_: did that bug show up after your workaround, or was that known before? [06:12] The second bug? That showed up before the workaround. [06:12] ok [06:12] This is caused because occasionally the vfsmnt point for a lower dentry is NULL. [06:13] A little bit of background. [06:13] When a unionfs dentry is opened, unionfs in turn opens all the corresponding dentries on the lower filesystems (the branches). === ml68 [n=michel@141.71.102-84.rev.gaoland.net] has joined #ubuntu-meeting [06:14] Unionfs stores the correspondng underlying dentries and their vfsmount points. [06:15] pkl_: this all revolves around the vfs changes for apparmor? [06:15] It is relatef. apparmor changes the vfs interface so much more vfs functions expect the vfsmount. [06:16] In this case, however, the vfs dentry_open() function has always expected a vfsmount, and so it is unrelated to the vfs changes. [06:16] ^unrelated^not caused [06:17] Ok, guess I can't bad mouth kees now :) [06:17] Again, the underlying reason appears to be a race condition. [06:17] Still working on the cause. [06:18] pkl_: have you talked to unionfs upstream about this at all? [06:18] As a temporary workaround, I have put a hack in the unionfs_open code to remember the correct vfsmount point for each branch. In the case of the liveCD there's two branches, and therefore two vfsmount points. [06:19] if the vfsmount point lookup for a dentry fails, the hack replaces it with the correct vfsmount point previously remembered. [06:19] This fixes the oops, and it is definately the cause. [06:20] pkl_: Ok, two workarounds sounds like decent progress, so excellent work. When can we get these in lum for an upload? [06:20] Now I have establised the causes I can email the unionfs guys. [06:21] I was planning on putting the hacks into lum in a couple of hours (I have to strip them out of my heavily hacked unionfs code). [06:22] pkl_: ok, ping me when you're ready and I'll get an upload out [06:22] OK [06:22] thanks [06:24] So I sent an email to the kernel-team list explaining what our current focus should be [06:25] At this point in release cycle is where we are usually the busiest [06:26] I don't forsee any problems like we've had in the past, simply because the upstream kernel stabalized very well and we stuck to stock code so strictly [06:27] but we do have some minor usage bugs and some regressions that we should handle in the next few weeks [06:27] and we need to keep a close eye on the incoming bugs (and bugs marked NEW) to make sure we aren't over looking anything major [06:29] amitk, rtg_, kylem: Anything major you guys are working on that needs to get in with beta?

I just noticed you cherry-picked it... [06:33] amitk: merged that already [06:33] kylem: yeah, that's what I started to think till I got down to the atl2 part [06:34] ok, atl2 should be put into lum [06:34] anyone up for doing that? [06:34] i can since i brought it up [06:34] zul: you sure can...good man :) [06:35] zul: shoot a pull request to #ubuntu-kernel when you can, thanks [06:35] no probs [06:35] the other major issue is the header post{inst,rm} scripts that I am working on [06:35] needed for DKMS and feisty compatibility [06:37] BenC: why is it more complicated then just fixing the perl expressions? [06:37] rtg_: because the scripts from kernel-package need to be munged a bit [06:37] debconf stuff removed/disabled, variable replacements taken into account [06:38] rtg_: fixing the perl replacements in kernel-package doesn't fix our kernel builds, and the scripts are not 1-to-1 compatible with our build system [06:39] Well, I haven't delved into it in that level of detail. === mdz [n=mdz@adsl-75-24-193-31.dsl.pltn13.sbcglobal.net] has joined #ubuntu-meeting [06:40] Ok, any other business?
