Description Vladimir Kondratiev 2006-03-23 06:27:00 UTC

Most recent kernel where this bug did not occur:
did not tested this in earlier kernels

Distribution:
Fedora Core 5

Hardware Environment:
Software Environment: 
Vanilla 2.6.16 kernel
[root@vkondra-mobl ~]# cat /proc/version
Linux version 2.6.16 (root@vkondra-mobl) (gcc version 4.1.0 20060304 (Red Hat
4.1.0-3)) #1 PREEMPT Mon Mar 20 13:43:30 IST 2006

Problem Description:
sleeping function called in invalid context.

Steps to reproduce:

Enable audit rule to track all "exit" syscalls:
auditctl -a exit,always -S exit

run anything, 'ls' is OK. This will trigger the following error:

Yes, bad. We cannot perform sleeping things in an RCU callback.

I don't think that audit_log_exit() call is in the correct place anyway. 
It's not actually logging an "exit" - it's currently logging the free of a
task_struct, which can happen an arbitrary time later and can be performed
by a different task (or by none at all, as in this case).

IOW: shouldn't we be calling audit_log_exit() from within do_exit()??

A backportable-to-2.6.16.1 fix is needed, I'd suggest.

Comment 2 Srinivasa DS 2006-05-23 00:24:38 UTC

vladimir
 I failed to recreate the problem on 2.6.16.12 and in 2.6.17-rc4,it seems that
bug is fixed. Please verify.

Comment 3 Srinivasa DS 2006-05-23 06:40:18 UTC

It looks like audit_log_start() in audit_log_exit() was using GFP_KERNEL in
2.6.16 which might caused to block. Whereas in newer kernel(2.6.16.**) it has
been changed to gfp_mask(which is GFP_ATOMIC). Hence we will not see the problem.
=================================================================
in 2.6.16.rc4 at audit_log_exit()
==================================
for (aux = context->aux; aux; aux = aux->next) {

                ab = audit_log_start(context, GFP_KERNEL, aux->type);
                if (!ab)
                        continue; /* audit_panic has been called */

==============================================
In 2.6.16.** at audit_log_exit()
==============================================
for (aux = context->aux; aux; aux = aux->next) {

                ab = audit_log_start(context, gfp_mask, aux->type);
                if (!ab)
                        continue; /* audit_panic has been called */
====================================================

Comment 4 Srinivasa DS 2006-05-23 21:31:36 UTC

This is the patch,which already included in the newer kerel.

Comment 5 Vladimir Kondratiev 2006-05-24 09:15:00 UTC

I checked with 2.6.16.18. Same scenario leads to the same oops.

In 2.6.16.x tree, bug is still here.

More precisely, I got the following, before complete freeze:

Vladimir

From comment#1 made by Andrew morton,It is clear that audit_log_exit() is not in 
the correct place(i,e in __put_task_struct_cb()) and that is causing the problem.
 So there is already a patch in 2.6.17-rc5 which removes audit_free() from 
__put_task_struct_cb() and inserts it in do_exit().

This is patch is not in 2.6.16.18 and hence we can reproduce the problem.

Here is the patch,which fixes the bug 

http://www.kernel.org/git/?p=linux/kernel/git/aegl/linux-2.6.git;a=commitdiff;
h=fa84cb935d4ec601528f5e2f0d5d31e7876a5044;
hp=d6fe3945b42d09a1eca7ad180a1646e585b8594f

Please test this patch.

Comment 9 Vladimir Kondratiev 2006-05-29 06:07:25 UTC

sorry, I missed this point. Will check with 2.6.17-rc5 and update.

Comment 10 Srinivasa DS 2006-05-30 05:35:25 UTC

Iam backporting the patch for 2.6.16.18 kernel.

Verified with 2.6.17-rc5-git10

No oops. Everything works as it should be.

Who shall mark it "fixed"?
