  Please use reply-to-all next time. It makes me less likely to miss the

  dmesg after boot doesn't help us. It is a dump of a kernel internal
buffer of messages so it is cleared after reboot. I had hoped the machine
is usable after a crash but apparently it's not. Could you reconfigure your
syslog to put all messages in one file (because now part of the oops
message apparently ends in /var/log/warn or something like that)? Or setup
something like netconsole (see Documentation/networking/netconsole.txt) to
grab the oops. Thanks!

Looking into your messages file, the oops now is:

So this time there's nothing about filesystems in the trace. Maybe this is
a generic mm bug - adding mm list to CC.

Yeah, I know and was wondering why you'd want that. Sorry,
misunderstanding. Maybe for memory layout for something..

Anyway I reproduced again and while the segfault is always the same
(in libgio, same address etc) one problem is that the oops does not show
up immediately but seems to be delayed (?) after the initial corruption
(pool[2970]: segfault ..) which is why the syslog file also shows other
random processes oopsing - often the running shell, cron, or nscd.
In the one below I caused "the real oops" by running 'du'.
Curiously, if the first corruption doesn't kill the system, I can then
subsequently run gthumb (at least for a moment).

So armed with multiple running shells I finally managed to save the dmesg
to NFS. It doesn't get any more complete than this and again shows the
ext4 stacktrace from before. So maybe it really is generic kmem corruption
and ext4 looking at symlinks/inodes is just the victim.

This looks a lot like the signature of a crash we've experienced
recently [repeatedly :-(] on a 2.6.38 ubuntu/natty kernel.  It's caused
by the irq stack at the bottom of a per cpu area overflowing over the
per cpu slab caches in the next lower cpus' PCA.  When this occurs,
'kmem -s' in crash will show lots of "invalid page" messages.  Many of
those addresses will be in some cpu's PCAs.

Overflow, in our case, was causes by attempt to remove an exiting task's
apparmor profile when the task has a loooong chain of replacedby
profiles.  Our environment is an openstack nova compute node [thousands
of them, actually -- why upgrading kernel is not an option any time
soon] where an overly simplistic chef recipe is replacing various aa
profiles periodically, resulting in O(1000) replaced by profiles to be
freed, recursively, on the irq stack [rcu deferred processing].

Canonical has reported this bug to the apparmor developers and have a
patch for 2.6.38+ that avoids the problem on profile free by removing
the recursion.  Still doesn't filter duplicate profiles up front so we
do still have the replacedby chain growing w/o bounds until the task is
killed/restarted.

Canonical verified that the bug exists in the mainline kernel in the
past week or so.

Of course, this might be something completely different.

Lee

That certainly seems to be the case.  As near as I can tell from the
stack trace, you're doing a readdir(), and the crash is happening in
ext4_htree_store_dirent() --- the stack address to ext4_follow_link()
makes no sense given the rest of the strack trace, and anyway,
ext4_follow_link() doesn't do any memory allocation.

So that means this:
> [  106.643048]  [<c0236ed9>] ext4_htree_store_dirent+0x29/0x110

Almost certainly corresponds to the following call to kzalloc:

	/* Create and allocate the fname structure */
	len = sizeof(struct fname) + dirent->name_len + 1;
	new_fn = kzalloc(len, GFP_KERNEL);

dirent->name_len is a unsigned char, and struct fname is around 48
bytes or so.  So len is never going to be larger than 300 bytes, and
never smaller than 48 bytes, which is certainly valid input as far as
kzalloc() is concerned.

So it's very likely that the crash in __kmalloc() is probably caused
by the internal slab/slub data structures getting scrambled.

Good to know. Unfortunately I'm still at a loss why apparently only
gthumb can trigger this; I had not noticed any other problems with 3.6.0
before that (ran it for half a day, desktop use).

For giggles I rebuilt with SLAB instead of SLUB, but no luck; same
segfault and delayed oopsie. I also collected an strace, but I cannot
really see anything out of the ordinary - it starts, loads things,
traverses directories and then segfaults.

I've put the earlier full dmesg and the strace into
http://hoho.dyndns.org/~holger/ext4-oops-3.6.0/ - maybe it helps someone
else.

Any suggestions for memory debugging? I saw several options in the
kernel config (under "Kernel Hacking") but was not sure what to enable.

Holger
