I thought this was already resolved.

And I don't think the kernel is buggy, this is expected behaviour. With
this commit (actually, there were several patches) /sbin/init respects
SIGSTOP if the caller has rights to send it, this change is intentional.
I'd even say this is fix.

Note that even root can't stop init, SIGSTOP should be sent from the
parent namespace, or from ptracer. And ptracer could obviously ptrace_stop()
init even before this patch.


But, Kumar, could you please provide more info? I downloaded
ltp-full-20081130.tgz, and I see that ptrace03.c does:

                        /* since Linux 2.6.26, it's allowed to trace init,
                           so just skip this test case */
                        if (i == 0 && tst_kvercmp(2,6,25) > 0) {
                                tst_resm(TCONF,
                                         "this kernel allows to trace init");
                                continue;
                        }

So, could you explain which test traces init?

Oleg.

Yes, so did I. We had asked for more info/confirmation before, most recently
on Apr 25 http://lkml.org/lkml/2009/4/25/132, although finding the LTP
test like below would have helped :-)

There's one important aspect here: _if_ a change results in 
user-space visible behavioral change, it does not matter how correct 
it is in the grand scheme of things. (beyond plain bugfixes solving 
crashes, etc.) What matters is whether there's any app out there 
that might possibly rely on the old behavior.

The LTP testcase might be synthetic, and it could be fixed and the 
commit might even end up being correct - but some thought should be 
expended on compatibility and real-life impact (and scope) here - 
not just on strict 'correctness'.

Yes, agreed.

But hopefully in this case we can't break the user-space. Because the
tracing of /sbin/init is special, and this was forbidden till 2.6.25.
Not only you can make the system unusable, it is very easy to crash
the kernel if you trace init. I don't think any "good" app can rely
on the wrong old behaviour, but of course any behavioral change is
dangerous.

And please note that the old behaviour was known to be wrong. If we
take the sub-namespace inits into account, it was very wrong. Of course,
we can add the special is_global_init() hack to preserve the current
behaviour at least for the root namespace, but this doesn't look good.

As far as I can tell, this seams to be fixed by the intel-2.7.1 driver, 
and the bug only happened with UXA.
I did some minor testing and I couldn't trigger the bug. (earlier 
discussion in http://lkml.org/lkml/2009/4/23/587)
So this seams to be a user space bug, fixed in the intel-2.7.1 bug fix 
release (intel-2.7.0 still has the issue).

Well..  order-1 GFP_ATOMIC allocations are unreliable.  The networking
code should hanlde the situation and recover.  I assume that is
happening in this case?

Perhaps we did something in that code after 2.6.29 which increased the
frequency of the order-1 allocation attempts?  Maybe earlier kernels
used order-0 all the time?  Those are much more reliable.

Yes, the driver has recovered in all cases so far.

I think something happened to change the allocation as I never saw these O(1)
failures before with these particular drivers. I put in a few test printk's and
the buffers were 700-800 bytes long, and I would not expect them to require more
than an O(0) allocation.

I pushed 2.6.30-rc6 hard for ~12 hours without any recurrence of the problem.
Given the relative infrequency of the error, this certainly does not indicate a
fix in recent code. I will be trying to force it again.

I wonder if this is related:

http://bugzilla.kernel.org/show_bug.cgi?id=13069

Both point to post 2.6.29... Hmm.

I have been unable to repeat the problem with recent kernels - I am now running
2.6.30-rc6. This regression should probably be dropped even though it may show
up when 2.6.30 is released.

Jonathan, there's a side-issue reported there, us running out of 
lockdep space. Could you try this commit from -tip:

d80c19d: lockdep: increase MAX_LOCKDEP_ENTRIES and MAX_LOCKDEP_CHAINS

(which i'll get to Linus in the next ~24 hours.) Maybe that allows 
lockdep to report the reason for the deadlock.

that crash is in reiserfs_for_each_xattr(), during sys_unlink()'s 
xattr teardown.

There's been a good deal of reiserfs changes in this cycle - some 
touch the xattr code as well. Some of them fairly late in the cycle, 
in the last two weeks:

 earth4:~/tip> gll v2.6.29..linus --since=two-weeks-ago fs/reiserfs/
 2a32ceb: Fix races around the access to ->s_options
 677c9b2: reiserfs: remove privroot hiding in lookup
 b82bb72: reiserfs: dont associate security.* with xattr files
 ab17c4f: reiserfs: fixup xattr_root caching
 edcc37a: Always lookup priv_root on reiserfs mount and keep it
 5a6059c: reiserfs: Expand i_mutex to enclose lookup_one_len

Martin, you could try a blind revert of say ... ab17c4f, which looks 
the most suspect and which is also a rather large commit.

Or/and you could try a bisect - perhaps accelerated via:

   git bisect start fs/reiserfs/

looks like wireless related - the dependency that connects the

Oleg says in that thread that it's as-designed, and followup 
questions were not replied to (yet).

But ... a relevant seeming commit has been bisected to so this 
shouldnt be ignored that easily.

I think there's a fix already for this in the works, but it hasn't been merged
yet.  It looks like Jeff has just posted some reiserfs fixes. :-)

I'd say Martin should try Jeff's pending patches before a revert or 
before starting a bisection.  Either apply them from 
http://lkml.org/lkml/2009/5/17/6, or pull from
  git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git for-next
or wait for them to appear in Linus' tree...

I for one didn't test the post v2.6.30-rc5 changes to reiserfs, but I 
did try them _together_ with the four pending patches on a system with 
reiserfs root filesystem and extended attributes disabled in the config. 
Everything is fine here after almost a week uptime.

Yes, this bug is known and is fixed with "[patch 2/4] [PATCH] reiserfs:
deal with NULL xattr root w/ xattrs disabled"

It seems the crash has been rewritten by hand. I don't see
any cmd40x_init(), I guess it's about cmd640 chipset, then
cmd640x_init()

I don't see very recent changes in drivers/ide/cmd640.c
But there are some in drivers/ide/ide-io.c and drivers/ide/ide-cd.c
for this cycle.

Especially commit a1f9a89c90b4ac143c5b6054c2a157572b272cd2 which
fixed in -rc2:

     [<10116068>] intr_return+0x0/0x4

Looks very similar. But the crash reported in this ticket is for -rc4, which means the
issue was still there after this fix or it's another one.
Adding some more Cc's.

Frederic, is the oops reproducible?  Is 2.6.30-rc6 any better?

Does it help if you disable CONFIG_BLK_DEV_CMD640?
(this system doesn't have CMD640 chipset)

Sorry, I'm not the author of this bug report and I don't have this
hardware. I've just added you in Cc's :-)

But I'm adding the bug reporter in Cc.

Rob, could you test above Bartlomiej's suggestion?

Yes, I think this is false alarm. Perhaps I missed something, and
I am waiting for more info from Kumar, but it looks like ltp was
already changed to skip the "{ PTRACE_ATTACH, 1, EPERM }" test
on kernels after 2.6.25

Btw., why did the patch (and the revert) make any difference to the 
test? Timing differences look improbable.

Because before this series /sbin/init always ignored SIGSTOP. Now,
ptracer does PTRACE_ATTACH and exits without clearing the pending
SIGSTOP. init dequeues this signal and becomes TASK_STOPPED.

Consider:

	$ sleep 1000 &
	[1] 875

	$ grep State: /proc/`pidof sleep`/status
	State:  S (sleeping)

	$ perl -e 'syscall 101, 16, 0+shift, 0,0' `pidof sleep`    # just PTRACE_ATTACH + exit

	[1]+  Stopped                 sleep 1000

	$ grep State: /proc/`pidof sleep`/status
	State:  T (stopped)

This is the "normal" behaviour, afaics the same happens with init now.

It's the change from

	!signal_group_exit(signal)

to

	!sig_kernel_only(signr)

and quite frankly, I still don't see the point.

The comment seems to be wrong too:

    If SIGSTOP/SIGKILL originate from a descendant of container-init they are
    never queued (i.e dropped in sig_ignored() in an earler patch).
    
    If SIGSTOP/SIGKILL originate from parent namespace, the signal is queued
    and container-init processes the signal.

since the bug was that the SIGSTOP (from within the same container) was 
_not_ ignored like the comment says.

Previously,

	!signal_group_exit(signal)

meant: we do not know what should we do, let's ignore this signal.
Unless the multithreaded init does exec, in this case we should
respect SIGKILL.

With the recent changes, sig_kernel_only() means: we already checked
we should handle SIGKILL/SIGSTOP when this signal was queued.

Yes, the changelog could be better because it ignores ptrace issues. But
this was discussed,

From http://marc.info/?t=123222433100001

	Yes we should handle SIGSTOP fine if it sent from the parent namespace.

	Also. Currently it is possible to ptrace the global init, but even
	ptracer can't stop it (but ptrace_stop() works). With these patches
	ptracer can stop init.

	I forgot to mention this behaviour change, imho this side-effect
	is good.

So, at least this change is not "by accident".

All the main details on this are on the freedesktop bugzilla[1]. I can
confirm it's still a problem and I've been tracking the intel-next
tree for testing.

Fundamentally the problem is that X can't allocate any memory when KMS
is enabled on my chipset. Without knowing how memory should be
allocated from the kernel by the X driver I haven't been able to look
into it deeper. I've had some feedback from the intel guys but nothing
recently.

As always I stand ready to run tests and/or provide additional
diagnostics if required.

This one really looks like a compiler bug (the undefined symbol is an 
internal gcc one: ".L192"). And the driver that gets it (kl5kusb105) has 
not actually had any changes since 2.6.29 - although header files that it 
includes obviously do have some, so it's entirely possible that some 
infrastructure change causes it to trigger.

Martin hit another bug with his compiler (an ICE in gcc, fixed by commit 
26a9a418237c0b06528941bca693c49c8d97edbe), which is why I'm so willing to 
blame that.

This one seems to have become "not-a-bug". Yes, LTP used to check that you 
cannot send SIGSTP to init, but people do want to send signals to init 
(especially when they are inside pid-namespace containers), and as long as 
it's only a LTP test that already got modified (and not some actual 
real-life usage), I'm considering this a "test failed because it was 
testing for behavior that we want to change" at least for now.

Thanks a lot, this really helps! :-)

I've closed all of the bugs above.

It may be worth tracking a possible regression introduced with -rc6 as a 
result of http://bugzilla.kernel.org/show_bug.cgi?id=13259.

A new warning that was added in drivers/acpi/processor_throttling.c 
(commit 4973b22a: 'ACPI processor: reset the throttling state once it's 
invalid') may be triggering in cases where it shouldn't. It seems to 
trigger during boot and on 'cat /proc/acpi/processor/*/throttling'.
Otherwise it's probably relatively harmless.

See the comments starting at #23 for details.

Cheers,
FJP

Hmm.  It's really better if you file a separate bug for that with a reference
to the previous discussion.

Done (after doing additional debugging):
http://bugzilla.kernel.org/show_bug.cgi?id=13389

Marked as regression and set as blocking for #13070.

[Bug #13179] CD-R: wodim intermittent failures

[Rafael J. Wysocki]

This message has been generated automatically as a part of a report
of regressions introduced between 2.6.29 and 2.6.30.

The following bug entry is on the current list of known regressions
introduced between 2.6.29 and 2.6.30.  Please verify if it still should
be listed and let me know (either way).

2.6.31-rc1-git3: Reported regressions 2.6.29 -> 2.6.30

[Rafael J. Wysocki]

[NOTES:
 * I hope you notice the jump of the number of reported regressions after 2.6.30
   was released.
 * Please let me know which of these bugs have been fixed already (ideally
   please also provide the name of the fix commit).
 * The post-2.6.30 reports were flooded by the megre window noise that made
   them very difficult to track.]

This message contains a list of some regressions introduced between 2.6.29 and
2.6.30, for which there are no fixes in the mainline I know of.  If any of them
have been fixed already, please let me know.

If you know of any other unresolved regressions introduced between 2.6.29
and 2.6.30, please let me know either and I'll add them to the list.
Also, please let me know if any of the entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

Last I heard the reporter was going to attempt a bisect, that was a 
while ago. I don't really have any suggestions other than that.

I've been having trouble reliably bisecting; sometimes seemingly-bad
kernels work OK and other times thought-OK kernels fail even though I've
stopped Gnome and HAL.

At this point I'm suspecting intermittent hardware failure and am
getting set up to test on a similar machine.

2.6.30-rc7: Reported regressions from 2.6.29

[Rafael J. Wysocki]

[NOTE:
 Bug entries for which I know there are working patches get the
 RESOLVED / PATCH_ALREADY_AVAILABLE status in the Bugzilla, which
 makes it easier to check if the patches have been merged before sending
 out the list.  For this reason, please let me know of working patches
 for any of the regression list items or (better) change the status of the bug
 entries in case you know of a working patch (in which case please also add
 a link to the patch to the appropriate bug entry).]

This message contains a list of some regressions from 2.6.29, for which there
are no fixes in the mainline I know of.  If any of them have been fixed already,
please let me know.

If you know of any other unresolved regressions from 2.6.29, please let me know
either and I'll add them to the list.  Also, please let me know if any of the
entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.
