Back in April, I posted an RFC patch set to help mitigate a common issue
where a timer gets armed just before it is freed, and when the timer
goes off, it crashes in the timer code without any evidence of who the
culprit was. I got side tracked and never finished up on that patch set.
Since this type of crash is still our #1 crash we are seeing in the field,
it has become a priority again to finish it.
This is v3 of that patch set. Thomas Gleixner posted an untested version
that makes timer->function NULL as the flag that it is shutdown. I took that
code, tested it (fixed it up), added more comments, and changed the
name to timer_shutdown_sync(). I also converted it to use WARN_ON_ONCE()
instead of just WARN_ON() as Linus asked for.
I then created a trivial coccinelle script to find where del_timer*()
is called before being freed, and converted them all to timer_shutdown*()
(There was a couple that still used del_timer() instead of del_timer_sync()).
I also updated DEBUG_OBJECTS_TIMERS to check from where the timer is ever
armed, to calling of timer_shutdown_sync(), and it will trigger if a timer
is freed in between. The current way is to only check if the timer is armed,
but that means it only triggers if the race condition is hit, and with
experience, it's not run on enough machines to catch all of them. By triggering
it from the time the timer is armed to the time it is shutdown, it catches
all potential cases even if the race condition is not hit.
I went though the result of the cocinelle script, and updated the locations.
Some locations were caught by DEBUG_OBJECTS_TIMERS as the coccinelle script
only checked for timers being freed in the same function as the del_timer*().
Ideally, I would have the first patch go into this rc cycle, which is mostly
non functional as it will allow the other patches to come in via the respective
subsystems in the next merge window.
Changes since v2: https://lore.kernel.org/all/20221027150525.753064657@goodmis.org/
- Talking with Thomas Gleixner, he wanted a better name space and to remove
the "del_" portion of the API.
- Since there's now a shutdown interface that does not synchronize, to keep
it closer to del_timer() and del_timer_sync(), the API is now:
timer_shutdown() - same as del_timer() but deactivates the timer.
timer_shutdown_sync() - same as del_timer_sync() but deactivates the timer.
- Added a few more locations that got converted.

Back in April, I posted an RFC patch set to help mitigate a common issue
where a timer gets armed just before it is freed, and when the timer
goes off, it crashes in the timer code without any evidence of who the
culprit was. I got side tracked and never finished up on that patch set.
Since this type of crash is still our #1 crash we are seeing in the field,
it has become a priority again to finish it.
This is v3 of that patch set. Thomas Gleixner posted an untested version
that makes timer->function NULL as the flag that it is shutdown. I took that
code, tested it (fixed it up), added more comments, and changed the
name to timer_shutdown_sync(). I also converted it to use WARN_ON_ONCE()
instead of just WARN_ON() as Linus asked for.
I then created a trivial coccinelle script to find where del_timer*()
is called before being freed, and converted them all to timer_shutdown*()
(There was a couple that still used del_timer() instead of del_timer_sync()).
I also updated DEBUG_OBJECTS_TIMERS to check from where the timer is ever
armed, to calling of timer_shutdown_sync(), and it will trigger if a timer
is freed in between. The current way is to only check if the timer is armed,
but that means it only triggers if the race condition is hit, and with
experience, it's not run on enough machines to catch all of them. By triggering
it from the time the timer is armed to the time it is shutdown, it catches
all potential cases even if the race condition is not hit.
I went though the result of the cocinelle script, and updated the locations.
Some locations were caught by DEBUG_OBJECTS_TIMERS as the coccinelle script
only checked for timers being freed in the same function as the del_timer*().
Ideally, I would have the first patch go into this rc cycle, which is mostly
non functional as it will allow the other patches to come in via the respective
subsystems in the next merge window.
Changes since v2: https://lore.kernel.org/all/20221027150525.753064657@goodmis.org/
- Talking with Thomas Gleixner, he wanted a better name space and to remove
the "del_" portion of the API.
- Since there's now a shutdown interface that does not synchronize, to keep
it closer to del_timer() and del_timer_sync(), the API is now:
timer_shutdown() - same as del_timer() but deactivates the timer.
timer_shutdown_sync() - same as del_timer_sync() but deactivates the timer.
- Added a few more locations that got converted.

Back in April, I posted an RFC patch set to help mitigate a common issue
where a timer gets armed just before it is freed, and when the timer
goes off, it crashes in the timer code without any evidence of who the
culprit was. I got side tracked and never finished up on that patch set.
Since this type of crash is still our #1 crash we are seeing in the field,
it has become a priority again to finish it.
This is v3 of that patch set. Thomas Gleixner posted an untested version
that makes timer->function NULL as the flag that it is shutdown. I took that
code, tested it (fixed it up), added more comments, and changed the
name to timer_shutdown_sync(). I also converted it to use WARN_ON_ONCE()
instead of just WARN_ON() as Linus asked for.
I then created a trivial coccinelle script to find where del_timer*()
is called before being freed, and converted them all to timer_shutdown*()
(There was a couple that still used del_timer() instead of del_timer_sync()).
I also updated DEBUG_OBJECTS_TIMERS to check from where the timer is ever
armed, to calling of timer_shutdown_sync(), and it will trigger if a timer
is freed in between. The current way is to only check if the timer is armed,
but that means it only triggers if the race condition is hit, and with
experience, it's not run on enough machines to catch all of them. By triggering
it from the time the timer is armed to the time it is shutdown, it catches
all potential cases even if the race condition is not hit.
I went though the result of the cocinelle script, and updated the locations.
Some locations were caught by DEBUG_OBJECTS_TIMERS as the coccinelle script
only checked for timers being freed in the same function as the del_timer*().
Ideally, I would have the first patch go into this rc cycle, which is mostly
non functional as it will allow the other patches to come in via the respective
subsystems in the next merge window.
Changes since v2: https://lore.kernel.org/all/20221027150525.753064657@goodmis.org/
- Talking with Thomas Gleixner, he wanted a better name space and to remove
the "del_" portion of the API.
- Since there's now a shutdown interface that does not synchronize, to keep
it closer to del_timer() and del_timer_sync(), the API is now:
timer_shutdown() - same as del_timer() but deactivates the timer.
timer_shutdown_sync() - same as del_timer_sync() but deactivates the timer.
- Added a few more locations that got converted.

We are hitting a common bug were a timer is being triggered after it is
freed. This causes a corruption in the timer link list and crashes the
kernel. Unfortunately it is not easy to know what timer it was that was
freed. Looking at the code, it appears that there are several cases that
del_timer() is used when del_timer_sync() should have been.
Add a timer_shutdown_sync() that not only does a del_timer_sync() but will mark
the timer as terminated in case it gets rearmed, it will trigger a WARN_ON. The
timer_shutdown_sync() is more likely to be used by developers that are about to
free a timer, then using del_timer_sync() as the latter is not as obvious
to being needed for freeing. Having the word "shutdown" in the name of the
function will hopefully help developers know that that function needs to
be called before freeing.
The added bonus is the marking of the timer as being freed such that it
will trigger a warning if it gets rearmed. At least that way if the system
crashes on a freed timer, at least we may see which timer it was that was
freed.
There's some situations that already know that the timer is shutdown and
does not need to perform the synchronization (or can not due to its
context). For these locations there's timer_shutdown() that only shuts
down the timer (prevents it from being rearmed) but does not add checks if
the timer is currently running.
This code is taken from Thomas Gleixner's "untested" version from my
original patch and modified after testing and with some other comments
from Linus addressed. As well as some extra comments added.

And if synchronization is already done, then at least timer_shutdown()
needs to be called.

And if synchronization is already done, then at least timer_shutdown()
needs to be called.

assumed that the timer is not running while being freed, so only
timer_shutdown() is used, and not timer_shutdown_sync().

DEBUG_OBJECTS_TIMERS is now checking if a timer is ever enqueued, and if
so, it must call timer_shutdown_sync() before freeing, otherwise
debug objects will trigger. This requires that once a timer is initialized
(and initialized for debug objects) it must not be re-initialized using
timer_setup(), as that will call the debug objects initialization code
again and trigger a bug if it was ever used.
As the mce reinitializes its timers on CPU hotplug, it must use
__init_timer() instead of timer_setup(), which will only initialize the
debug objects once.

There's been too many bugs happening where a timer is removed, either by
del_timer() or even del_timer_sync() but get's re-armed again by a
workqueue or some other task. Then the timer is freed while it's still
queued to go off. When the timer eventually goes off, as its content no
longer exists, it causes a crash in the timer code.
This is very hard to debug because all evidence of who added the timer is
gone.
Currently, DEBUG_OBJECTS_TIMER will trigger if this happens, but as this
only happens rarely (but in the field, thousands of times) and may depend
on performing various tasks (USB unplug, CPU hotplug, suspend and resume),
not to mention that enabling DEBUG_OBJECTS_TIMER has too much overhead to
run in the field, it seldom catches these types of bugs.
Now that timer_shutdown_sync() is to be called before freeing, move the
checks of DEBUG_OBJECTS_TIMER to if it ever gets armed to where
timer_shutdown_sync() is called. If there's a case where a timer is armed,
and then freed without calling timer_shutdown_sync() DEBUG_OBJECTS_TIMER
will now trigger on it.
This catches cases that are potential issues instead of just catching
when the race condition occurs.
Note, due to delayed workqueues that use timers but they themselves do not
supply a shutdown method, there's no way to be able to call
timer_shutdown() on delayed work timers correctly. Because of this, the
delayed work timers will add a state to inform the DEBUG_OBJECTS_TIMER
code that its a timer for a delayed work. The delayed work timers will be
treated the old way of only trigging an issue if its timer is active when
freed, but does not need to be shutdown first.
Work may be needed to make workqueue code also have a shutdown state.

Mhm, what exactly is the benefit of renaming the function?
Not that I'm against the change, but my thinking is more if there are
more functions which don't re-arm the time than those which do that then
why not forbid it in general?

Christian.

If it stays all DRM drivers in one patch then I guess it needs to go via
drm-misc, which for i915 would be okay I think in this case since patch
is extremely unlikely to clash with anything. Or split it up per driver
and then we can handle it in drm-intel-next once core functionality is in.
We do however have some more calls to del_timer_sync, where freeing is
perhaps not immediately next to the site in code, but things definitely
get freed like on module unload. Would we need to convert all of them to
avoid some, presumably new, warnings?

Ack.
I also wonder if we could do the completely trivially correct
conversions immediately.
I'm talking about the scripted ones where it's currently a
"del_timer_sync()", and the very next action is freeing whatever data
structure the timer is in (possibly with something like free_irq() in
between - my point is that there's an unconditional free that is very
clear and unambiguous), so that there is absolutely no question about
whether they should use "timer_shutdown_sync()" or not.
IOW, things like patches 03, 17 and 31, and at least parts others in
this series.
This series clearly has several much more complex cases that need
actual real code review, and I think it would help to have the
completely unambiguous cases out of the way, just to get rid of noise.
So I'd take that first patch, and a scripted set of "this cannot
change any semantics" patches early.

Ack.
I also wonder if we could do the completely trivially correct
conversions immediately.
I'm talking about the scripted ones where it's currently a
"del_timer_sync()", and the very next action is freeing whatever data
structure the timer is in (possibly with something like free_irq() in
between - my point is that there's an unconditional free that is very
clear and unambiguous), so that there is absolutely no question about
whether they should use "timer_shutdown_sync()" or not.
IOW, things like patches 03, 17 and 31, and at least parts others in
this series.
This series clearly has several much more complex cases that need
actual real code review, and I think it would help to have the
completely unambiguous cases out of the way, just to get rid of noise.
So I'd take that first patch, and a scripted set of "this cannot
change any semantics" patches early.

Timers are more often re-armed then not. I had to look for the
locations where del_timer*() was called just before freeing, and other
locations where they are freed later.
I didn't rename del_timer_sync() to timer_shutdown_sync(), this version
renamed the new "del_timer_shutdown()" to "timer_shutdown_sync()".
Maybe I'm just confused at what you are asking.

I'm happy to split this patch up. I just got a bit lazy and started
just grouping via entire subsystems. You should see the networking

Honestly, I think these need to be renamed, as "timer_shutdown()"
should be specific to the timer code, and not individual timers.
I'll start making a patch set that starts by renaming these timers,
then adds the timer_shutdown() API, and finished with the trivial
updates, and that will be a real "PATCH" (non RFC).
Linus, should I also add any patches that has already been acked by the
respective maintainer?

Honestly, I think these need to be renamed, as "timer_shutdown()"
should be specific to the timer code, and not individual timers.
I'll start making a patch set that starts by renaming these timers,
then adds the timer_shutdown() API, and finished with the trivial
updates, and that will be a real "PATCH" (non RFC).
Linus, should I also add any patches that has already been acked by the
respective maintainer?

After applying the patches attached below, everything compiles for me,
and there are no crashes. There are still various warnings, most in
networking. I know I need to apply some patch(es) to fix the networking
warnings, but I didn't entirely understand what exactly to apply, so
I didn't try.
Complete logs are at https://kerneltests.org/builders, on the bottom half
of the page (qemu tests, in the 'testing' column).
