I have an assorted collection of kmemleak reports for acpi, ext4 and
tty, not sure how to read these yet to fix so figure I'd at least post
them. To reproduce I can just dd=/dev/zero to some big file and played
some video.

Maybe a false positive caused by kmemleak not scanning the pgdata node_zones.

OK -- tested rc8 + a pull of your tree into mine. The bootup was really slow and something was just not going right. After a while memleak complained it had 8 kmemleak logs but I was not able to get my system usable enough to cat the file. In cases like these I wish I would hookup my ctrl-alt-del to kexec() a safe kernel. After a long period of time it seems X wished it would start, it tried and then flashed back to the tty. This kept repeating in a loop. I am not sure if the culprit was rc8 or the kmemleak branch merge -- I'll find out after I boot into rc8 in a few. These issues seem to be serious blockers, I don't tend to use video play but I suspect others do, after a decent amount of time playing the system becomes completely unusable. If you have any other patch suggestions let me know. I'll try to read the kmemleak docs too, maybe I can try to figure some of these out.

I highly doubt the issues are wireless-testing related so I will not bisect there. Since I am unable to get anything useful from the kernel to determine what may have gone sour, any suggestions on a path to bisect, or should I just do the whole tree?

I tried 2.6.31-rc8 from hpa's linux-2.6-allstable.git tree instead of Linus [1] as I already had that tree, git describe says: v2.6.31-rc8-15-gadda766 Testing this would be the same as testing Linus' blessed rc8 -- correct me I'm wrong. Contrary to what I expected this tree with the same config works well! I have compiled a fresh checkout of wireless-testing origin/master to double check the issue and it is indeed only present on wireless-testing. A diff stat between John's merge of 2.6.31-rc8 and current master branch on wireless-testing [2] doesn't reveal much other than wireless specific stuff, as expected, so it seems this may after all be introduced in a recent patches in wireless-testing. I still find this a bit odd given I see no others reporting major issues. My boot doesn't go very far, it stalls for a while after input devices are being detected, then it spits out a kmemleak warning about 13 kmemleaks. Here's a picture [3]. I didn't bother waiting as I did last time for X to try to come up, something is really wrong. I'll bisect wireless-testing in the morning, starting with a good marker at merge-2009-08-28 as that is when John pulled 2.6.31-rc8 (and I confirm a diff stat between that and v2.6.31-rc8 yields nothing as it should) and current master as the bad marker. I have 9 steps to go, will leave first step compiling overnight.

OK I tried this, I even 'rm -rf * ; git checkout -f' and .. merge-2009-08-28 tag yields the same issues, long lag upon bootup with some kmemleaks I cannot even get to check. So somehow something is different between merge-2009-08-28 and Linus' rc8. This is just bizarre so to be even safer I'm just going to do a fresh git clone on wireless-testing.

Hey John so I tested wireless-testing on the merge-2009-08-28 tag on a fresh git pull and verified this is indeed busted for me. Although I had tried hpa's linux-2.6-allstable on HEAD just to be sure I am now building Linus' tree from a fresh git clone on the v2.6.31-rc8 tag just to be double check this was indeed not a 2.6.31-rc8 issue but instead *something* on wireless-testing. What that something is is unclear to me still, I guess after all these tests I'll run a manual diff as git doesn't seem to be picking anything up.

As you determined, there is no difference between merge-2009-08-28 and v2.6.31-rc8. If one works and the other doesn't, then the main thing not working will be git... What is linux-2.6-allstable?

OK, then I can only guess that something went wrong in your bisection (e.g. dirty build, something not marked properly, etc). That, or different .config files between your linux-2.6-allstable build and the merge-2009-08-28 build of wireless-testing? John -- John W.

Well so remember I did a clean git clone of wireless-testing and the issue was still there, but I determined just now it seems rc8 from Linus does indeed also have the issue. For some reason the issue was not present on hpa's rc8 on linux-2.6-allstable.

It turns out Eric Paris' inotify patches are required to fix 2.6.31-rc8 for me.. I tested just one patch and it fixed my bootup lag: http://git.infradead.org/users/eparis/notify.git/commit/b962e7312ae87006aed6f68ceee94bdf8db08338 FWIW for that patch: Tested-by: Luis R. Rodriguez <lrodriguez@atheros.com> So -- you if you're like me and had issues with bootup lag on wireless-testing, you can probably fix your wireless-testing by pulling his patches: git pull git://git.infradead.org/users/eparis/notify.git for-linus I saw Linus had some other fixes but I'll wait for rc9 for that as my box seems reasonably stable right now.

Good news is Linus' rc8 tag *has the same issue* so the reason why wireless-testing has it is rc8 *does indeed have it*. So Peter, if there is something extra or missing from linux-2.6-allstable head it certainly fixed my issues, will have to try a new respin of it to ensure it wasn't a fluke. Odd thing too though is even my distribution kernel (karmic rc8 generic) works fine. At least now I can safely bisect between rc7 and rc8, or pull the kmemleaks branch and see if that fixed.

Maybe mplayer is just opening the tty for some user interaction. I managed to the same report just using "top" but it is not persistent, so it may be a false positive. -- Catalin ^ permalink raw reply [flat|nested] 26+ messages in thread

Yes, as soon as the next merge window opens. The leak only shows up when you mount and unmount a filesystem, which under normal circumstances doesn't happen a huge number of times on most systems. By the time it showed up it was late enough in the 2.6.31-rcX series that I figured it was better to wait until the next merge window. I didn't consider it a high priority bug. - Ted ^ permalink raw reply [flat|nested] 26+ messages in thread

Let me be a bit more precise this time: the leak happens at mount time because we're essentially doing this due to some code that was accidentally duplicated when it was being refactored: a = kmalloc(sizeof(...)*N, GFP_ATOMIC); ... a = kmalloc(sizeof(...)*N, GFP_ATOMIC); So a small amount of memory is leaked each time a filesystem is mounted. It doesn't become a huge problem unless you are repeatedly mounting and unmounting the same filesystem in a tight loop. - Ted ^ permalink raw reply [flat|nested] 26+ messages in thread

Thanks for the explanation -- this still does seem like something which could affect some users, say of, embedded systems which do need to remount, so while it may be a priority for an average user it seems high priority for embedded system users using ext4 and remounting a lot. Either way, I guess what I'm getting at is it seems rather odd to me we would not consider fixing some memory leaks on an rc release when we already have a fix prepared. I understand the merge window is closing in but we're not there yet -- and in worst case, can't we at least consider this fix after rc1? kmeleak reports seem rather useful, I'd hate to see more users told their memory leak issues won't be fixed until a later kernel release. That just seems... shitty. Luis ^ permalink raw reply [flat|nested] 26+ messages in thread
