[Notes:
* Some new regressions from 2.6.28 have been reported since the release of
2.6.29, so here's an update of the regression list.
* I could have missed some fixes due to the large amounts of stuff merged
recently. Please have a look at the list and let me know if I can drop
anything from it.
* I'm not going to track regressions from 2.6.27 any more.
* Next time I'll list regressions from 2.6.29 (after 2.6.30-rc1) and new
regressions from 2.6.28 (if any) will be appended to the list below as
"regressions introduced between 2.6.28 and 2.6.29".]
This message contains a list of some regressions from 2.6.28, 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 2.6.28, 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.

I prefer to have this checked against 2.6.30-rc1 once Linus released
that one. I think that I know the root cause for this one and it is
actually a hardware/firmware bug. Some Bluetooth dongles expect to have
the interrupt and bulk URBs available at the same time. Otherwise they
do pee in their pants.
Regards
Marcel

2.6.30-rc2-next-20090420:
My display *is* at full brightness, but I cannot adjust it,
because I'm missing some files:
[12:35] ikn:~# ls /sys/class/video_output
[12:35] ikn:~# ls /sys/class/backlight
[12:35] ikn:~# ls /proc/acpi

battery debug_level event ibm processor wakeup
button dsdt fadt info sleep
So I cannot adjust brightness. I saw that
/proc/acpi/video/VID/LCD0/brightness was not existing on 2.6.30-rc2-00195-g9f76208
either.
Bug or am I missing some new file location?

Hmm. I applied the commit that should fix it, but I applied it _after_
2.6.29. I was too scared to apply it late in the -rc and quite frankly
I'm not sure we should necessarily back-port it.
So I'm hoping that we can close it as "fixed", even though 2.6.29 will
have that particular regression - for those particular machines. It is,
after all, just a "where do we draw the line" kind of issue.
But I won't close it myself, and I leave it to others to argue whether it
really maybe should be back-ported after all.

This bug could be closed.
The performance regression is triggered by commit 1cf6e7d83bf3(mm:
task dirty accounting fix). Which has been reverted in 2.6.29.
For 2.6.30, commit 1cf6e7d83bf33(mm: task dirty accounting fix) and
1b5e62b42b55(writeback: double the dirty thresholds) were just merged
together. The latter one restores the iozone performance. (However
might deteriorate some writeback slowness bugs..)

please have this re-tested against 2.6.30-rc1 then we can work on

2.6.30-rc1 does not seem to be out (according to kernel.org); I can
test the latest git if that helps?

No, this shouldn't be listed as a regression from 2.6.28: if it's to be
counted as a regression at all, it's 2.6.23's regression from 2.6.22.
(We're about to deal with it in 2.6.30, but hardly worth backporting.)

I don't think that's a regression, nor really a bug. It looks cosmetic,
and likely to be fixed, but not really worth worrying about.

This went through bisection, but looking at the email log, I tend to
suspect that maybe Trenton marked some versions good even though they
weren't (because they got versions numbers from v2.6.27), and didn't
realize that that messes up bisection in a big way.
The bug _sounds_ like some deadlock due to lock problems - the shutdown
path often triggers locks that no other path really cares about. And we
had some lock problems in the sound subsystem that got fixed post-2.6.28,
for example.
And it looks like the problem is somewhere in sound shutdown:
12181 delete_module("snd_hda_codec", O_RDONLY|O_EXCL) = -1 EAGAIN (Resource temporarily unavailable) <0.000011>
So commits like 91054598f794fb5d8a0b1e747ff8e2e8fc2115b3 ("ALSA: pcm_oss,
fix locking typo") might explain it.

I'm okay with that. The problem causes some backwards compatibility
problems with existing apps that get confused by the large "offset"
number. The fix is going to cause problems too, but in a different way.
We'll work around it.

If you have actual apps that care, that's a different issue.
We do try to bend over backwards on ABI issues if it really is noticeable
for applications. Now, in this case, if you can just fix your app to not
care (because it really was badly written in the first place to even
notice), then that is the _much_ superior solution.
But if you actually have binary-only commercial apps that break, we'll do
a compatibility thing rather than the 0 that already got merged.
Although I don't really even see what we can sanely do except for the 0
case. We could put the virtual address in there instead of zero (I forget
what old kernels used to do - whatever magic value the anonymous mappings
got, it wasn't really designed as an important value in its own right, it
was designed to trigger the "we can merge these vma's" logic.

Yep, we can fix the app to ignore that field for anonymous mappings.

For anonymous mappings, the older kernels put the starting address of
the VMA (from the point of view of the app) as the offset. Until the
recent change, new kernels still did this for most VMAs, but the stack
offset was a 64-bit value with no obvious relation to the VMA start address.

For anonymous mappings, the older kernels put the starting address of
the VMA (from the point of view of the app) as the offset. Until the
recent change, new kernels still did this for most VMAs, but the stack
offset was a 64-bit value with no obvious relation to the VMA start address.

Yep, we can fix the app to ignore that field for anonymous mappings.

Yes, that's what I told Chris too.
But asked for more info, suspecting his app was already broken.

No, what they put there was something that in most cases matched the
starting address of the VMA; but try moving that VMA with mremap (and
an old /proc/<pid>/maps!) and you'll see that the "offset" remained
unchanged even when the starting address of the VMA was changed.
(The offset remaining constant so that rmap can locate the VMA's pages
and unmap them, despite their being mapped at different virtual
addresses in parent and child after a move in one of them.)
... so I think your app was indeed already broken, wasn't it?
It's also unclear why you'd want to use the offset field for the
starting address of the VMA, when /proc/<pid>/maps already shows
the starting address of the VMA. I think you've more to tell us!

Yeah, given the above the app was broken. We just didn't run into any
cases where the assumption caused any problems.
Also, it's not so much that we were relying on the offset value for
anything, so much as we were parsing the file and had made some
assumptions about valid offsets for anonymous memory.
Anyways, we'll fix it going forward to simply ignore the offset for
anonymous memory.

I'm okay with that. The problem causes some backwards compatibility
problems with existing apps that get confused by the large "offset"
number. The fix is going to cause problems too, but in a different way.
We'll work around it.

Is it appropriate for me to respond to these things?
I was wondering about that. Someone had mentioned that I should trust
the bisect, even when it takes me into "other versions", and it was
taking me through 2.6.27, which I thought was just really weird.
Would you like me to try the bisect again with a little more
diligence, or do you think it can be found with the info given? It
may take a week or so, due to being a bit busy.

Is it appropriate for me to respond to these things?
I was wondering about that. Someone had mentioned that I should trust
the bisect, even when it takes me into "other versions", and it was
taking me through 2.6.27, which I thought was just really weird.
Would you like me to try the bisect again with a little more
diligence, or do you think it can be found with the info given? It
may take a week or so, due to being a bit busy.
Thanks

Yes. I added you to the cc exactly because it was hard for me to judge
from the email discussion that is linked to in the regression list whether
you actually _did_ mark some versions good because of confusion about the
version numbering.
That would certainly explain why bisection didn't seem to work.
But it's not the _only_ reason bisection doesn't work. Sometimes you can
be as careful as possible, but if it's a bug that is even _slightly_ flaky
(timing-dependencies etc), and the bisection marked something good that
shouldn't have been (or vice versa, but that's unusual), then the
bisection end result won't be right.
So you may well have done everything right, and I'm not trying to blame
you. I just was hoping that maybe that confusion would explain why the
bisection didn't seem to pinpoint anything sane..

It would be good, especially if this bug doesn't end up being solved some
other way... And slow results are better than no results at all ;)

Oh, didn't know you CC'd me. I have just been searching for my name
to try and keep up to date on threads I participated in, because the
list volume is just too much.

This gave me a bit of a chuckle. ROFL. I didn't think you were
_blaming_ me. And even if you were, I'd just say "I'M HUMAN MAN". ;)
It is very well possible that I simply booted the wrong kernel, seeing
I had like 20 to choose from at the time, after doing all those
bisects. This time, I will make the new kernels the default so that
it is impossible to happen again, assuming that is what happened. I
will also stop and start alsa 2 or 3 times, in case it is a deadlock
timing issue as you mentioned.
I'm glad to know that I shouldn't be switching kernel versions though.
I thought that was really crazy.

This gave me a bit of a confused look. Better, how so? And what would
provoke such a comment? Linus was simply being excessively polite,
which is a good side to error on I suppose, but I don't need excessive
politeness. I didn't in any way think he had blamed me for anything.
And why would I? He hadn't said anything that indicated he was.
Yeah, having trouble getting into your head on that comment. _confused look_

The first one looks similar, if not identical. The second one
doesn't, because my problem happens on 2.6.29 only, not 2.6.28.
Either way, the unload problem with the module didn't happen in
2.6.28.

The Gentoo bug entry too is about a regression _after_ 2.6.28. :-)
I.e. 2.6.28.y. are unaffected. It's actually just the downstream
duplicate of the kernel.org bug entry.

Interdependencies between ALSA modules have changed. The Gentoo init
scripts attempted to unload them in an order which deadlocked modprobe
due to dependencies. The fix for Gentoo is to just not unload the
modules on system shutdown. My Gentoo/amd64 Mac mini was affected by
this too; fixed by userland update.

While that is interesting, I am not seeing that problem on my Gentoo
box (the macbook), which is completely up-to-date. 2.6.28 works, and
2.6.29 doesn't. Same init scripts, different kernels.
And sure, I could put a comment on the rmmod, in the init script, but
IMO that would be a hack around a _bug_. Which is fine for me. But,
is it worth leaving the issue in the kernel?

Note that the respective update changed /etc/conf.d/alsasound (a local
configuration file) to include
UNLOAD_ON_STOP="no"
KILLPROC_ON_STOP="no"
This change by update is not activated by a mere emerge; one needs to
incorporate that change with dispatch-conf or an equivalent method.
(Or simply edit the file to have these variables set to "no".)

Is it a kernel issue if a script attempts to unload a busy module, then
fails to proceed? I wouldn't think so.
But more importantly, is this init scripts related bug really what's
happening at your system? Or do you actually experience an entirely
different bug?

I run dispatch-conf every time I update. It did not set it to no by
default. I do see the option though.

I don't know really. It worked before, now it doesn't. But, now I'm
recalling something you said earlier. They are being done in the
wrong order. The gentoo bug mentions the correct order. I hadn't
realized that.

It could be. I will try it out when I get home from work, and get
back to you. That would be cool if it was a simple init script
problem. Cause then I don't have to do anymore git bisects. ;)

It could be. I will try it out when I get home from work, and get
back to you. That would be cool if it was a simple init script
problem. Cause then I don't have to do anymore git bisects. ;)

Yes, the order is what causes this, you can close the bug.
Sorry for wasting everyone's time. I thought it was a kernel bug
because I had not needed to update my gentoo system to make it happen.
Thanks.

Note that the respective update changed /etc/conf.d/alsasound (a local
configuration file) to include
UNLOAD_ON_STOP="no"
KILLPROC_ON_STOP="no"
This change by update is not activated by a mere emerge; one needs to
incorporate that change with dispatch-conf or an equivalent method.
(Or simply edit the file to have these variables set to "no".)

Is it a kernel issue if a script attempts to unload a busy module, then
fails to proceed? I wouldn't think so.
But more importantly, is this init scripts related bug really what's
happening at your system? Or do you actually experience an entirely
different bug?

The first one looks similar, if not identical. The second one
doesn't, because my problem happens on 2.6.29 only, not 2.6.28.
Either way, the unload problem with the module didn't happen in
2.6.28.

I don't think that's a regression, nor really a bug. It looks cosmetic,
and likely to be fixed, but not really worth worrying about.

This went through bisection, but looking at the email log, I tend to
suspect that maybe Trenton marked some versions good even though they
weren't (because they got versions numbers from v2.6.27), and didn't
realize that that messes up bisection in a big way.
The bug _sounds_ like some deadlock due to lock problems - the shutdown
path often triggers locks that no other path really cares about. And we
had some lock problems in the sound subsystem that got fixed post-2.6.28,
for example.
And it looks like the problem is somewhere in sound shutdown:
12181 delete_module("snd_hda_codec", O_RDONLY|O_EXCL) = -1 EAGAIN (Resource temporarily unavailable) <0.000011>
So commits like 91054598f794fb5d8a0b1e747ff8e2e8fc2115b3 ("ALSA: pcm_oss,
fix locking typo") might explain it.

Hi Rafael,
Yes, it is still a problem. I have identified it as far down to being
an alsa problem. Please follow the other thread related to this. I
posted some more recent data, with strace info and such. I also used
git bisect to narrow it down. I wasn't, however, able to understand
what was happening exactly in the code.
If you need more info, or want me to try something, please just let me know.
Thanks.

Hi Rafael,
Yes, it is still a problem. I have identified it as far down to being
an alsa problem. Please follow the other thread related to this. I
posted some more recent data, with strace info and such. I also used
git bisect to narrow it down. I wasn't, however, able to understand
what was happening exactly in the code.
If you need more info, or want me to try something, please just let me know.
Thanks.

Oops, sorry, I should make clear that it is not an alsa problem
specifically, but an alsa hda-intel driver issue, which is related to
alsa.

I must admit I still don't have an idea of the root cause on this
one. It still looks like some kind of memory corruption to me,
but no smoking gun so far. The one patch in 2.6.30 that might have
fixed it in the driver didn't help.
Anyway here's a patch to buy some time. Johannes, would this be
an acceptable band-aid for now?
Sergey, can you test this patch? It doesn't fix anything but hopefully
makes your system survive the bug. I gave it a quick test by forcing
one of the rate indexes to a bad value.

Subject: [PATCH] mac80211: be more resilient in the face of bad rate indexes
If for whatever reason the rate tables contain invalid rates,
ieee80211_get_tx_rate will warn and return NULL, causing some
drivers to crash. Those that don't will subsequently hit a
BUG_ON() in rate.c. Instead, return a valid rate structure from
ieee80211_get_tx_rate() and only WARN() in rate_control_get_rate().

This is going to make it print two warnings for one occurrence of the
problem though. I'd much prefer to put something into minstrel.c to
catch when _it_ returns bogus values and in that case return 0, that way
at least the bandaid is restricted to the code it patches up.

Ok, then maybe something like this?
I think this covers most of the bases: if the driver is returning crap or
the ->cb gets corrupted, it'll get caught in tx_status. If minstrel
stuffs a -1 in the first slot for any other reason we'll get a warning
before get_tx_rate and a hopefully valid index gets substituted.

It might be easier to print this in hex -- that way things like 0x6b are
more apparent?

Dave, dri guys,
Could you take a look at this circular dependency please (below)? I
observe it when suspending laptop with radeon drm loaded and with
lockdep enabled. It seems that the root of the problem is that
various vm ops such as drm_vm_open, drm_mmap) are called with mm
semaphore taken, and take dev->struct_mutex. On the other hand,
drm_rmmap_locked is called with dev->struct_mutex, and calls mtrr_del
which depends on mm semaphore indirectly.
What do you think?

Dave, dri guys,
Could you take a look at this circular dependency please (below)? I
observe it when suspending laptop with radeon drm loaded and with
lockdep enabled. It seems that the root of the problem is that
various vm ops such as drm_vm_open, drm_mmap) are called with mm
semaphore taken, and take dev->struct_mutex. On the other hand,
drm_rmmap_locked is called with dev->struct_mutex, and calls mtrr_del
which depends on mm semaphore indirectly.
What do you think?

Yes, there are real lock inversions now due to the GTT mmap code. It's
going to be a pain to fix (I tried getting the mmap_sem -> struct_mutex
path to go away, but the fact that mmap_sem is held over the fault
handler pretty much kills that). It's high on the list, though.

Shouldn't it be possible to relax this given that in the fault()
handler, the mmap_sem() is taken in read mode only. This means that it
should be deadlock-safe (but still a little ugly) to take the mmap_sem()
in read mode when the struct mutex is held.
Another quick way to fix potential deadlocks, would be to take the
struct mutex in the following way in fault():
if (!mutex_trylock(&dev->struct_mutex)) {
needs_resched();
return VM_FAULT_NOPAGE;
}
