[patch V2 0/4] sched/mmcid: Cure mode transition woes

[Thomas Gleixner]

This is a follow up to the V1 submission:

     https://lore.kernel.org/20260129210219.452851594@kernel.org

Ihor and Shrikanth reported hard lockups which can be tracked back to the recent
rewrite of the MM_CID management code.

  1) The from task to CPU ownership transition lacks the intermediate
     transition mode, which can lead to CID pool exhaustion and a
     subsequent live lock. That intermediate mode was implemented for the
     reverse operation already but omitted for this transition as the
     original analysis missed a few possible scheduling scenarios.

  2) Weakly ordered architectures can observe inconsistent state which
     causes them to make the wrong decision. That leads to the same problem
     as with #1.

The following series addresses these issue and fixes another albeit harmless
inconsistent state hickup which was found when analysing the above issues.

With these issues addressed the last change optimizes the bitmap
utilization in the transition modes.

The series applies on Linus tree and passes the selftests and a thread pool
emulator which stress tests the ownership transitions.

Changes vs. V1:

   - Move the mm_cid_fixup_tasks_to_cpus() wrapping where it belongs (patch 1)

   - Add barriers before and after the fixup functions to prevent CPU
     reordering of the mode stores - Mathieu

   - Update change logs - Mathieu

Delta patch against V1 is below

[patch V2 1/4] sched/mmcid: Prevent live lock on task to CPU mode transition

[Thomas Gleixner]

Ihor reported a BPF CI failure which turned out to be a live lock in the
MM_CID management. The scenario is:

A test program creates the 5th thread, which means the MM_CID users become
more than the number of CPUs (four in this example), so it switches to per
CPU ownership mode.

At this point each live task of the program has a CID associated. Assume
thread creation order assignment for simplicity.

   T0     CID0  runs fork() and creates T4
   T1 	  CID1
   T2 	  CID2
   T3 	  CID3
   T4       ---   not visible yet

T0 sets mm_cid::percpu = true and transfers its own CID to CPU0 where it
runs on and then starts the fixup which walks through the threads to
transfer the per task CIDs either to the CPU the task is running on or drop
it back into the pool if the task is not on a CPU.

During that T1 - T3 are free to schedule in and out before the fixup caught
up with them. Going through all possible permutations with a python script
revealed a few problematic cases. The most trivial one is:

   T1 schedules in on CPU1 and observes percpu == true, so it transfers
      its CID to CPU1

   T1 is migrated to CPU2 and schedule in observes percpu == true, but
      CPU2 does not have a CID associated and T1 transferred its own to
      CPU1

      So it has to allocate one with CPU2 runqueue lock held, but the
      pool is empty, so it keeps looping in mm_get_cid().

Now T0 reaches T1 in the thread walk and tries to lock the corresponding
runqueue lock, which is held causing a full live lock.

There is a similar scenario in the reverse direction of switching from per
CPU to task mode which is way more obvious and got therefore addressed by
an intermediate mode. In this mode the CIDs are marked with MM_CID_TRANSIT,
which means that they are neither owned by the CPU nor by the task. When a
task schedules out with a transit CID it drops the CID back into the pool
making it available for others to use temporarily. Once the task which
initiated the mode switch finished the fixup it clears the transit mode and
the process goes back into per task ownership mode.

Unfortunately this insight was not mapped back to the task to CPU mode
switch as the above described scenario was not considered in the analysis.

Apply the same transit mechanism to the task to CPU mode switch to handle
these problematic cases correctly.

As with the CPU to task transition this results in a potential temporary
contention on the CID bitmap, but that's only for the time it takes to
complete the transition. After that it stays in steady mode which does not
touch the bitmap at all.

[patch V2 2/4] sched/mmcid: Protect transition on weakly ordered systems

   system_call_vectored_common+0x15c/0x2ec

The task on CPU11 is running the CID ownership mode change fixup function
and is stuck on a runqueue lock. The task on CPU23 is trying to get a CID
from the pool with the same runqueue lock held, but the pool is empty.

After decoding a similar issue in the opposite direction switching from per
task to per CPU mode the tool which models the possible scenarios failed to
come up with a similar loop hole.

This showed up only once, was not reproducible and according to tooling not
related to a overlooked scheduling scenario permutation. But the fact that
it was observed on a PowerPC system gave the right hint: PowerPC is a
weakly ordered architecture.

The transition mechanism does:

    WRITE_ONCE(mm->mm_cid.transit, MM_CID_TRANSIT);
    WRITE_ONCE(mm->mm_cid.percpu, new_mode);

    fixup()
    
    WRITE_ONCE(mm->mm_cid.transit, 0);

mm_cid_schedin() does:

    if (!READ_ONCE(mm->mm_cid.percpu))
       ...
       cid |= READ_ONCE(mm->mm_cid.transit);

so weakly ordered systems can observe percpu == false and transit == 0 even
if the fixup function has not yet completed. As a consequence the task will
not drop the CID when scheduling out before the fixup is completed, which
means the CID space can be exhausted and the next task scheduling in will
loop in mm_get_cid() and the fixup thread can livelock on the held runqueue
lock as above.

This could obviously be solved by using:
     smp_store_release(&mm->mm_cid.percpu, true);
and     
     smp_load_acquire(&mm->mm_cid.percpu);

but that brings a memory barrier back into the scheduler hotpath, which was
just designed out by the CID rewrite.

That can be completely avoided by combining the per CPU mode and the
transit storage into a single mm_cid::mode member and ordering the stores
against the fixup functions to prevent the CPU from reordering them.

That makes the update of both states atomic and a concurrent read observes
always consistent state.

The price is an additional AND operation in mm_cid_schedin() to evaluate
the per CPU or the per task path, but that's in the noise even on strongly
ordered architectures as the actual load can be significantly more
expensive and the conditional branch evaluation is there anyway.

[patch V2 3/4] sched/mmcid: Drop per CPU CID immediately when switching to per task mode

[Thomas Gleixner]

When a exiting task initiates the switch from per CPU back to per task
mode, it has already dropped its CID and marked itself inactive. But a
leftover from an earlier iteration of the rework then reassigns the per
CPU CID to the exiting task with the transition bit set.

That's wrong as the task is already marked CID inactive, which means it is
inconsistent state. It's harmless because the CID is marked in transit and
therefore dropped back into the pool when the exiting task schedules out
either through preemption or the final schedule().

Simply drop the per CPU CID when the exiting task triggered the transition.

[patch V2 4/4] sched/mmcid: Optimize transitional CIDs when scheduling out

[Thomas Gleixner]

During the investigation of the various transition mode issues
instrumentation revealed that the amount of bitmap operations can be
significantly reduced when a task with a transitional CID schedules out
after the fixup function completed and disabled the transition mode.

At that point the mode is stable and therefore it is not required to drop
the transitional CID back into the pool. As the fixup is complete the
potential exhaustion of the CID pool is not longer possible, so the CID can
be transferred to the scheduling out task or to the CPU depending on the
current ownership mode.

The racy snapshot of mm_cid::mode which contains both the ownership state
and the transition bit is valid because runqueue lock is held and the fixup
function of a concurrent mode switch is serialized.

Assigning the ownership right there not only spares the bitmap access for
dropping the CID it also avoids it when the task is scheduled back in as it
directly hits the fast path in both modes when the CID is within the
optimal range. If it's outside the range the next schedule in will need to
converge so dropping it right away is sensible. In the good case this also
allows to go into the fast path on the next schedule in operation.

With a thread pool benchmark which is configured to cross the mode switch
boundaries frequently this reduces the number of bitmap operations by about
30% and increases the fastpath utilization in the low single digit
percentage range.

I think this could've been smp_store_release(), but this is the slow
path so nobody cares and this is nicely symmetric.

I'm not sure the store-release would work here. What load-acquire
would it pair with ?

The purpose here -- per the comment is to ensure the fixup stuff is
visible before the TRANSIT bit goes 0, store-release ensures that.

That pairs with whatever cares about this barrier now.

Please keep it as two full barriers as it is here. I'm not sure the
store-release proposed by PeterZ works. I'll have to find time to do
a litmus test, but I'm busy at the moment.

Now that I think about it some more, I think my advice about adding
smp_mb() before rq lock/after rq unlock was wrong.

The store setting transit will be ordered by rq _unlock_ which acts
as a release barrier, and store clearing transit will be ordered by
rq _lock_ acting as an acquire barrier. Those pair with the respective
rq unlock/lock in the scheduler.

So AFAIU we can remove those two useless smp_mb().

Thoughts ?

Thanks,

Mathieu

I thought about this and stopped reading memory-barriers.txt after brain
started to hurt.

        acquire A
        store   B
        release A

        acquire C
        store   D
        release C

A and C are independent of each other as are B and D. So according to
the docs acquire C can be reordered before release A. So far so
good. But what's unclear to me is whether this scenarion is possible:

        acquire A
        acquire C
        store   D
        release C
        store   B
        release A

because that would screw up stuff badly.

sched/mmcid: Optimize transitional CIDs when scheduling out

During the investigation of the various transition mode issues
instrumentation revealed that the amount of bitmap operations can be
significantly reduced when a task with a transitional CID schedules out
after the fixup function completed and disabled the transition mode.

At that point the mode is stable and therefore it is not required to drop
the transitional CID back into the pool. As the fixup is complete the
potential exhaustion of the CID pool is not longer possible, so the CID can
be transferred to the scheduling out task or to the CPU depending on the
current ownership mode.

The racy snapshot of mm_cid::mode which contains both the ownership state
and the transition bit is valid because runqueue lock is held and the fixup
function of a concurrent mode switch is serialized.

Assigning the ownership right there not only spares the bitmap access for
dropping the CID it also avoids it when the task is scheduled back in as it
directly hits the fast path in both modes when the CID is within the
optimal range. If it's outside the range the next schedule in will need to
converge so dropping it right away is sensible. In the good case this also
allows to go into the fast path on the next schedule in operation.

With a thread pool benchmark which is configured to cross the mode switch
boundaries frequently this reduces the number of bitmap operations by about
30% and increases the fastpath utilization in the low single digit
percentage range.

sched/mmcid: Drop per CPU CID immediately when switching to per task mode

When a exiting task initiates the switch from per CPU back to per task
mode, it has already dropped its CID and marked itself inactive. But a
leftover from an earlier iteration of the rework then reassigns the per
CPU CID to the exiting task with the transition bit set.

That's wrong as the task is already marked CID inactive, which means it is
inconsistent state. It's harmless because the CID is marked in transit and
therefore dropped back into the pool when the exiting task schedules out
either through preemption or the final schedule().

Simply drop the per CPU CID when the exiting task triggered the transition.

sched/mmcid: Protect transition on weakly ordered systems

Shrikanth reported a hard lockup which he observed once. The stack trace
shows the following CID related participants:

  watchdog: CPU 23 self-detected hard LOCKUP @ mm_get_cid+0xe8/0x188
  NIP: mm_get_cid+0xe8/0x188

   make_task_dead+0x0/0x178
   system_call_exception+0x128/0x390
   system_call_vectored_common+0x15c/0x2ec

The task on CPU11 is running the CID ownership mode change fixup function
and is stuck on a runqueue lock. The task on CPU23 is trying to get a CID
from the pool with the same runqueue lock held, but the pool is empty.

After decoding a similar issue in the opposite direction switching from per
task to per CPU mode the tool which models the possible scenarios failed to
come up with a similar loop hole.

This showed up only once, was not reproducible and according to tooling not
related to a overlooked scheduling scenario permutation. But the fact that
it was observed on a PowerPC system gave the right hint: PowerPC is a
weakly ordered architecture.

The transition mechanism does:

    WRITE_ONCE(mm->mm_cid.transit, MM_CID_TRANSIT);
    WRITE_ONCE(mm->mm_cid.percpu, new_mode);

    fixup()

    WRITE_ONCE(mm->mm_cid.transit, 0);

mm_cid_schedin() does:

    if (!READ_ONCE(mm->mm_cid.percpu))
       ...
       cid |= READ_ONCE(mm->mm_cid.transit);

so weakly ordered systems can observe percpu == false and transit == 0 even
if the fixup function has not yet completed. As a consequence the task will
not drop the CID when scheduling out before the fixup is completed, which
means the CID space can be exhausted and the next task scheduling in will
loop in mm_get_cid() and the fixup thread can livelock on the held runqueue
lock as above.

This could obviously be solved by using:
     smp_store_release(&mm->mm_cid.percpu, true);
and
     smp_load_acquire(&mm->mm_cid.percpu);

but that brings a memory barrier back into the scheduler hotpath, which was
just designed out by the CID rewrite.

That can be completely avoided by combining the per CPU mode and the
transit storage into a single mm_cid::mode member and ordering the stores
against the fixup functions to prevent the CPU from reordering them.

That makes the update of both states atomic and a concurrent read observes
always consistent state.

The price is an additional AND operation in mm_cid_schedin() to evaluate
the per CPU or the per task path, but that's in the noise even on strongly
ordered architectures as the actual load can be significantly more
expensive and the conditional branch evaluation is there anyway.

sched/mmcid: Prevent live lock on task to CPU mode transition

Ihor reported a BPF CI failure which turned out to be a live lock in the
MM_CID management. The scenario is:

A test program creates the 5th thread, which means the MM_CID users become
more than the number of CPUs (four in this example), so it switches to per
CPU ownership mode.

At this point each live task of the program has a CID associated. Assume
thread creation order assignment for simplicity.

   T0     CID0  runs fork() and creates T4
   T1 	  CID1
   T2 	  CID2
   T3 	  CID3
   T4       ---   not visible yet

T0 sets mm_cid::percpu = true and transfers its own CID to CPU0 where it
runs on and then starts the fixup which walks through the threads to
transfer the per task CIDs either to the CPU the task is running on or drop
it back into the pool if the task is not on a CPU.

During that T1 - T3 are free to schedule in and out before the fixup caught
up with them. Going through all possible permutations with a python script
revealed a few problematic cases. The most trivial one is:

   T1 schedules in on CPU1 and observes percpu == true, so it transfers
      its CID to CPU1

   T1 is migrated to CPU2 and schedule in observes percpu == true, but
      CPU2 does not have a CID associated and T1 transferred its own to
      CPU1

      So it has to allocate one with CPU2 runqueue lock held, but the
      pool is empty, so it keeps looping in mm_get_cid().

Now T0 reaches T1 in the thread walk and tries to lock the corresponding
runqueue lock, which is held causing a full live lock.

There is a similar scenario in the reverse direction of switching from per
CPU to task mode which is way more obvious and got therefore addressed by
an intermediate mode. In this mode the CIDs are marked with MM_CID_TRANSIT,
which means that they are neither owned by the CPU nor by the task. When a
task schedules out with a transit CID it drops the CID back into the pool
making it available for others to use temporarily. Once the task which
initiated the mode switch finished the fixup it clears the transit mode and
the process goes back into per task ownership mode.

Unfortunately this insight was not mapped back to the task to CPU mode
switch as the above described scenario was not considered in the analysis.

Apply the same transit mechanism to the task to CPU mode switch to handle
these problematic cases correctly.

As with the CPU to task transition this results in a potential temporary
contention on the CID bitmap, but that's only for the time it takes to
complete the transition. After that it stays in steady mode which does not
touch the bitmap at all.

Hello all,

While I evaluated v6.19 kernel, I observed a BUG KASAN. The KASAN is recreated
in stable manner by running the test case zbd/013 of blktests [1] on some of my
test systems. I bisected and found that this patch as the commit 007d84287c74
triggered the KASAN. When I reverted this patch from v6.19 kernel, the KASAN
disappeared. Of note is that the KASAN symptom slightly varies for each run. I
observed KASAN slab-use-after-free [2], use-after-free [3] and slab-out-of-
bounds [4]. All those KASANs happened "in sched_mm_cid_exit".

Actions for fix will be appreciated. If I can help by trying trial some patches
on my test systems, please let me know.

And none of them make any sense. The patch does:

 -				mm_cid_transit_to_task(current, this_cpu_ptr(mm->mm_cid.pcpu));
 +				mm_drop_cid_on_cpu(mm, this_cpu_ptr(mm->mm_cid.pcpu));

Both access mm->mm_cid and mm->mm_cid.pcpu. mm is valid at that point as
this is way before the task disconnects from the mm.

The new code also accesses the CID bitmap which is at the end of
mm_struct. But the subsequent mm_cid_fixup_cpus_to_tasks(mm) touches all
of those too. So none of this makes any sense at all.

Can you please decode these symbols (file/line) so that we actually see
which access is flagged by KASAN?

Also .config and compiler version would be helpful.

Keeping the splats below for the KASAN folks to digest.

Thanks,

Could you please reproduce with the below added?

Just to double check that that cid value isn't out of bounds.

Ok. That's useful and I think I know what's going on.

fork() switches to per CPU mode and sets the TRANSIT bit on the task and
the CPU.

While the task is out in user space and therefore not scheduling, other
tasks are exiting and when this task exits it hits the mode change.

It still has the transit bit set in both task::mm::mm_cid:cid and in the
per CPU cid store. sched_mm_cid_remove_user() clears the TRANSIT bit in
the task and drops the CID, but it does not touch the per CPU storage.

That's functionally correct because a CID is only owned by the CPU when
the ONCPU bit is set, which is mutually exclusive with the TRANSIT flag.

Now mm_drop_cid_on_cpu() assumes for the wrong reason that the CID is
CPU owned because the prior mode was per CPU. So it clears the (not set)
ONCPU bit and then invokes clear_bit() with an insanely large bit
number because TRANSIT is set (bit 29). Duh.

Can you please try the fix below?

Thanks

Thanks for the action. I have applied the patch to v6.19 kernel, and reproduced
the KASAN. The added WARN was printed as follows. (Now I'm trying the fix patch
candidate that Thomas shared in another post)

Thomas, the fix patch worked! I applied the patch on top of v6.19 kernel, then
the KASAN is no longer observed. I confirmed it with my two test nodes. Thank
you very much for the swift fix :)

In case the patch will be posted as a formal one,

Tested-by: Shin'ichiro Kawasaki <shinichiro.kawasaki@wdc.com>

P.S. I stop working here tonight. If my response will be required, I will do so
     tomorrow.

[PATCH] sched/mmcid: Don't assume CID is CPU owned on mode switch

[Thomas Gleixner]

Shinichiro reported a KASAN UAF, which is actually an out of bounds access
in the MMCID management code.

   CPU0						CPU1
   						T1 runs in userspace
   T0: fork(T4) -> Switch to per CPU CID mode
         fixup() set MM_CID_TRANSIT on T1/CPU1
   T4 exit()
   T3 exit()
   T2 exit()
						T1 exit() switch to per task mode
						 ---> Out of bounds access.

As T1 has not scheduled after T0 set the TRANSIT bit, it exits with the
TRANSIT bit set. sched_mm_cid_remove_user() clears the TRANSIT bit in
the task and drops the CID, but it does not touch the per CPU storage.
That's functionally correct because a CID is only owned by the CPU when
the ONCPU bit is set, which is mutually exclusive with the TRANSIT flag.

Now sched_mm_cid_exit() assumes that the CID is CPU owned because the
prior mode was per CPU. It invokes mm_drop_cid_on_cpu() which clears the
not set ONCPU bit and then invokes clear_bit() with an insanely large
bit number because TRANSIT is set (bit 29).

Prevent that by actually validating that the CID is CPU owned in
mm_drop_cid_on_cpu().

FWIW, I actually hit this bug yesterday on my laptop with 6.19 kernel,
so it's not only theoretical.

The stack decode showed the very same code path.

% scripts/faddr2line vmlinux 'sched_mm_cid_exit+0xdf'

This happened only once, and can't be reproduced since then, though.
I must have been a very bad lock yesterday.
