This is new to -rc4-mm1.

Is the patch "reiser4-sb_sync_inodes-cleanup.patch" likely to be the culprit?

Someone tried to put a "/" in a kobject name, which is not allowed. Actually the name seems to be set to:

	"Intel(R) 830M/845G/852GM/855GM/865G/915G Framebuffer Driver"

which is a bit verbous if you want to create a directory name :)

thanks,

I don't think that part of the driver has changed in some time. Is there something new in your trees which would trigger this?

Seems like a fix such as this will be needed:

Any idea what actually causes that?

BTW, it doesn't seem to happen with gcc 2.95. Can you send me your .config? I'll double-check.

-- Dave

You won't see this error with gcc < 3.4 .

The kernel redefines "inline" to __attribute__((always_inline)). That's why gcc 3.4 (correctly) aborts the compilation if it can't inline it.

gcc 3.4 isn't able to inline a function that wasn't defined before the first usage with -fno-unit-at-a-time (and we are currently giving this flag on i386).
That's the reason why a function prototype for a "static inline" function doesn't help you.

I can send you my .config if these explanations weren't enough.

Interesting. I assume that this implies that older versions may not be inlining this even though we have asked them to. I'll go confirm there is no adverse effects from patch.

On Fri, 2005-05-13 at 09:53 -0500, steve would have written, if his mail client hadn't been broken:

Hmmm. We're hitting that bug when posix_acl_release() decrements the refcount on one of the inode's ACLs and it goes negative.

First glance at this had me suspecting that we were somehow calling clear_inode() twice... but since we clear the pointer to the ACL after calling posix_acl_release(), that seems unlikely -- unless you managed to get two CPUs in reiserfs_clear_inode() simultaneously for the same inode. Is this SMP? Is preempt enabled?

Can you reproduce it? If so, does it go away if you revert one or both of these:

i'll recompile without those two patches, and try it again.

Steve,

I can't reproduce your problem using 2.6.12-rc4 + the 2 patches. I created 50GB Reiserfs partition, copied a lot of data there (built linux sources in many exemplars) and issued 'grep -r blah *'. I also tried it with parallel writing to the partition - no help.

I wonder, could you please try 2.6.12-rc4 + the 2 patches and see if the warning still there ?

The above referred patches are (and they are also attached):
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12- rc4/2.6.12-rc4-mm1/broken-out/vfs-bugfix-two-read_inode-calles-
without.patch ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12-rc4/2.6.12-rc4-mm1/broken-out/__wait_on_freeing_inode-fix.patch

P.S. I wanted to try 2.6.12-rc4-mm2, but it OOPSes during the kernel load in my system. Then I switched to 2.6.12-rc4 in order not to fight with -mm2's problems.

Thanks. Are you using ACLs? If not, I think there's a more fundamental problem than a race with clear_inode() -- it's not that we're decrementing the use count on an ACL twice; it's that you think you have an ACL when there wasn't one. This could be a symptom of memory corruption... which has already been reported in reiserfs in 2.6.12-rc4.

Do you have CONFIG_REISERFS_CHECK enabled? Do you have preempt enabled?

Could we trouble you to try again on 2.6.12-rc3 with those two patches, please?

He did. That confirms you have ACLs enabled -- but are you actually _using_ them though? If not, the ACL fields whose refcount is causing this problem should never have been set in the first place.

Artem is putting together a patch which will put a magic value into the struct posix_acl and hence double-check whether we're really freeing one of them twice, or whether it's just that we're seeing memory corruption and what's in REISERFS_I(inode)->i_acl_{access,default} is pure noise.

It might also be useful to attempt to reproduce the problem with slab debugging turned on, but let's not change that variable just yet.

OK, then it sounds like what you've seen is a manifestation of the already-known reiserfs breakage in 2.6.12-rc4. Artem's patch didn't cause it; it just made it show itself.

Thanks.

So was the preemption enabled or disabled ?

Hi,
I felt that the arch_supports_kprobes use was a bit weird. The constant is not capitalized and is used as a variable for a C test.
I also added comments (CONFIG_KPROBES) to an #else and an #endif This patch is against 2.6.12-rc4-mm1, i386 compile tested.

Regards,
Frederik Deweerdt

There was an extremely long pause after it printed "Kernel panic ..." before it printed the traceback.

2.6.12-rc4 doesn't do this, neither does 2.6.12-rc3-mm2.

Any ideas where the problem is before I start looking?

Regards,

Richard

For reference, the oops below still occurs with 2.6.12-rc4-mm2. I've noticed that "/sbin/init: error while loading shared libraries: /sbin/init: Cannot allocate version reference table: Cannot allocate Memory" appears on the console just before the "Kernel panic".

2.6.12-rc4, 2.6.12-rc3-mm2 and 2.6.12-rc3-mm3 all work with the same root filesystem which suggests this is a kernel issue of some sort.

Richard Purdie:

Yeah, I couldn't work out a way of generating a patch which removes a zero-length file, so that's there as a reminder to ask Linus to remove the thing by hand.

OK..

This works :
