Paul E. McKenney	0c72ec11d8	locktorture: Print ratio of acquisitions, not failures ... commit 80c503e0e68fbe271680ab48f0fe29bc034b01b7 upstream. The __torture_print_stats() function in locktorture.c carefully initializes local variable "min" to statp[0].n_lock_acquired, but then compares it to statp[i].n_lock_fail. Given that the .n_lock_fail field should normally be zero, and given the initialization, it seems reasonable to display the maximum and minimum number acquisitions instead of miscomputing the maximum and minimum number of failures. This commit therefore switches from failures to acquisitions. And this turns out to be not only a day-zero bug, but entirely my own fault. I hate it when that happens!

Apart from this warning, lockdep internal functions like __bfs() should always be protected by current->lockdep_recursion to avoid potential deadlocks and data inconsistency, therefore add the current->lockdep_recursion on-and-off section to protect __bfs() in both lockdep_count_forward_deps() and lockdep_count_backward_deps() Reported-by: Qian Cai <cai@lca.pw> Signed-off-by: Boqun Feng <boqun.feng@gmail.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lkml.kernel.org/r/20200312151258.128036-1-boqun.feng@gmail.com Signed-off-by: Sasha Levin <sashal@kernel.org>	2020-04-17 10:50:05 +02:00

Waiman Long	b90976941e	locking/lockdep: Fix buffer overrun problem in stack_trace[] ... commit d91f3057263ceb691ef527e71b41a56b17f6c869 upstream. If the lockdep code is really running out of the stack_trace entries, it is likely that buffer overrun can happen and the data immediately after stack_trace[] will be corrupted. If there is less than LOCK_TRACE_SIZE_IN_LONGS entries left before the call to save_trace(), the max_entries computation will leave it with a very large positive number because of its unsigned nature. The subsequent call to stack_trace_save() will then corrupt the data after stack_trace[]. Fix that by changing max_entries to a signed integer and check for negative value before calling stack_trace_save().

The commit 91d2a812df ("locking/rwsem: Make handoff writer optimistically spin on owner") will allow a recently woken up waiting writer to spin on the owner. Unfortunately, if the owner happens to be RWSEM_OWNER_UNKNOWN, the code will incorrectly spin on it leading to a kernel crash. This is fixed by passing the proper non-spinnable bits to rwsem_spin_on_owner() so that RWSEM_OWNER_UNKNOWN will be treated as a non-spinnable target.

By testing with KCSAN, it is observable that the console gets spammed with data races reports, suggesting these are extremely frequent. Example data race report: read to 0xffff8ab24f403c48 of 4 bytes by task 221 on cpu 2: debug_spin_lock_before kernel/locking/spinlock_debug.c:85 [inline] do_raw_spin_lock+0x9b/0x210 kernel/locking/spinlock_debug.c:112 __raw_spin_lock include/linux/spinlock_api_smp.h:143 [inline] _raw_spin_lock+0x39/0x40 kernel/locking/spinlock.c:151 spin_lock include/linux/spinlock.h:338 [inline] get_partial_node.isra.0.part.0+0x32/0x2f0 mm/slub.c:1873 get_partial_node mm/slub.c:1870 [inline] <snip> write to 0xffff8ab24f403c48 of 4 bytes by task 167 on cpu 3: debug_spin_unlock kernel/locking/spinlock_debug.c:103 [inline] do_raw_spin_unlock+0xc9/0x1a0 kernel/locking/spinlock_debug.c:138 __raw_spin_unlock_irqrestore include/linux/spinlock_api_smp.h:159 [inline] _raw_spin_unlock_irqrestore+0x2d/0x50 kernel/locking/spinlock.c:191 spin_unlock_irqrestore include/linux/spinlock.h:393 [inline] free_debug_processing+0x1b3/0x210 mm/slub.c:1214 __slab_free+0x292/0x400 mm/slub.c:2864 <snip> As a side-effect, with KCSAN, this eventually locks up the console, most likely due to deadlock, e.g. .. -> printk lock -> spinlock_debug -> KCSAN detects data race -> kcsan_print_report() -> printk lock -> deadlock. This fix will 1) avoid the data races, and 2) allow using lock debugging together with KCSAN.

Wanpeng Li	89340d0935	Revert "locking/pvqspinlock: Don't wait if vCPU is preempted" ... This patch reverts commit 75437bb304 (locking/pvqspinlock: Don't wait if vCPU is preempted). A large performance regression was caused by this commit. on over-subscription scenarios. The test was run on a Xeon Skylake box, 2 sockets, 40 cores, 80 threads, with three VMs of 80 vCPUs each.

Waiman Long	91d2a812df	locking/rwsem: Make handoff writer optimistically spin on owner ... When the handoff bit is set by a writer, no other tasks other than the setting writer itself is allowed to acquire the lock. If the to-be-handoff'ed writer goes to sleep, there will be a wakeup latency period where the lock is free, but no one can acquire it. That is less than ideal. To reduce that latency, the handoff writer will now optimistically spin on the owner if it happens to be a on-cpu writer. It will spin until it releases the lock and the to-be-handoff'ed writer can then acquire the lock immediately without any delay. Of course, if the owner is not a on-cpu writer, the to-be-handoff'ed writer will have to sleep anyway. The optimistic spinning code is also modified to not stop spinning when the handoff bit is set. This will prevent an occasional setting of handoff bit from causing a bunch of optimistic spinners from entering into the wait queue causing significant reduction in throughput. On a 1-socket 22-core 44-thread Skylake system, the AIM7 shared_memory workload was run with 7000 users. The throughput (jobs/min) of the following kernels were as follows: 1) 5.2-rc6 - 8,092,486 2) 5.2-rc6 + tip's rwsem patches - 7,567,568 3) 5.2-rc6 + tip's rwsem patches + this patch - 7,954,545 Using perf-record(1), the %cpu time used by rwsem_down_write_slowpath(), rwsem_down_write_failed() and their callees for the 3 kernels were 1.70%, 5.46% and 2.08% respectively.

Bart Van Assche	12593b7467	locking/lockdep: Reduce space occupied by stack traces ... Although commit 669de8bda8 ("kernel/workqueue: Use dynamic lockdep keys for workqueues") unregisters dynamic lockdep keys when a workqueue is destroyed, a side effect of that commit is that all stack traces associated with the lockdep key are leaked when a workqueue is destroyed. Fix this by storing each unique stack trace once. Other changes in this patch are: - Use NULL instead of { .nr_entries = 0 } to represent 'no trace'. - Store a pointer to a stack trace in struct lock_class and struct lock_list instead of storing 'nr_entries' and 'offset'. This patch avoids that the following program triggers the "BUG: MAX_STACK_TRACE_ENTRIES too low!" complaint: #include <fcntl.h> #include <unistd.h> int main() { for (;;) { int fd = open("/dev/infiniband/rdma_cm", O_RDWR); close(fd); } } Suggested-by: Peter Zijlstra <peterz@infradead.org> Reported-by: Eric Biggers <ebiggers@kernel.org> Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Waiman Long <longman@redhat.com> Cc: Will Deacon <will.deacon@arm.com> Cc: Yuyang Du <duyuyang@gmail.com> Link: https://lkml.kernel.org/r/20190722182443.216015-4-bvanassche@acm.org Signed-off-by: Ingo Molnar <mingo@kernel.org>	2019-07-25 15:43:27 +02:00

Jan Stancek	e1b98fa316	locking/rwsem: Add missing ACQUIRE to read_slowpath exit when queue is empty ... LTP mtest06 has been observed to occasionally hit "still mapped when deleted" and following BUG_ON on arm64. The extra mapcount originated from pagefault handler, which handled pagefault for vma that has already been detached. vma is detached under mmap_sem write lock by detach_vmas_to_be_unmapped(), which also invalidates vmacache. When the pagefault handler (under mmap_sem read lock) calls find_vma(), vmacache_valid() wrongly reports vmacache as valid. After rwsem down_read() returns via 'queue empty' path (as of v5.2), it does so without an ACQUIRE on sem->count: down_read() __down_read() rwsem_down_read_failed() __rwsem_down_read_failed_common() raw_spin_lock_irq(&sem->wait_lock); if (list_empty(&sem->wait_list)) { if (atomic_long_read(&sem->count) >= 0) { raw_spin_unlock_irq(&sem->wait_lock); return sem; The problem can be reproduced by running LTP mtest06 in a loop and building the kernel (-j $NCPUS) in parallel. It does reproduces since v4.20 on arm64 HPE Apollo 70 (224 CPUs, 256GB RAM, 2 nodes). It triggers reliably in about an hour. The patched kernel ran fine for 10+ hours.

For reader, it is left intact on unlock for providing better debugging aid on crash dump and the unlock of one reader may not mean the lock is free.

Pull locking updates from Ingo Molnar: "The main changes in this cycle are: - rwsem scalability improvements, phase #2, by Waiman Long, which are rather impressive: "On a 2-socket 40-core 80-thread Skylake system with 40 reader and writer locking threads, the min/mean/max locking operations done in a 5-second testing window before the patchset were: 40 readers, Iterations Min/Mean/Max = 1,807/1,808/1,810 40 writers, Iterations Min/Mean/Max = 1,807/50,344/151,255 After the patchset, they became: 40 readers, Iterations Min/Mean/Max = 30,057/31,359/32,741 40 writers, Iterations Min/Mean/Max = 94,466/95,845/97,098" There's a lot of changes to the locking implementation that makes it similar to qrwlock, including owner handoff for more fair locking. Another microbenchmark shows how across the spectrum the improvements are: "With a locking microbenchmark running on 5.1 based kernel, the total locking rates (in kops/s) on a 2-socket Skylake system with equal numbers of readers and writers (mixed) before and after this patchset were: # of Threads Before Patch After Patch ------------ ------------ ----------- 2 2,618 4,193 4 1,202 3,726 8 802 3,622 16 729 3,359 32 319 2,826 64 102 2,744" The changes are extensive and the patch-set has been through several iterations addressing various locking workloads.

Waiman Long	a15ea1a35f	locking/rwsem: Guard against making count negative ... The upper bits of the count field is used as reader count. When sufficient number of active readers are present, the most significant bit will be set and the count becomes negative. If the number of active readers keep on piling up, we may eventually overflow the reader counts. This is not likely to happen unless the number of bits reserved for reader count is reduced because those bits are need for other purpose. To prevent this count overflow from happening, the most significant bit is now treated as a guard bit (RWSEM_FLAG_READFAIL). Read-lock attempts will now fail for both the fast and slow paths whenever this bit is set. So all those extra readers will be put to sleep in the wait list.

Waiman Long	5cfd92e12e	locking/rwsem: Adaptive disabling of reader optimistic spinning ... Reader optimistic spinning is helpful when the reader critical section is short and there aren't that many readers around. It makes readers relatively more preferred than writers. When a writer times out spinning on a reader-owned lock and set the nospinnable bits, there are two main reasons for that. 1) The reader critical section is long, perhaps the task sleeps after acquiring the read lock. 2) There are just too many readers contending the lock causing it to take a while to service all of them. In the former case, long reader critical section will impede the progress of writers which is usually more important for system performance. In the later case, reader optimistic spinning tends to make the reader groups that contain readers that acquire the lock together smaller leading to more of them. That may hurt performance in some cases. In other words, the setting of nonspinnable bits indicates that reader optimistic spinning may not be helpful for those workloads that cause it. Therefore, any writers that have observed the setting of the writer nonspinnable bit for a given rwsem after they fail to acquire the lock via optimistic spinning will set the reader nonspinnable bit once they acquire the write lock. Similarly, readers that observe the setting of reader nonspinnable bit at slowpath entry will also set the reader nonspinnable bit when they acquire the read lock via the wakeup path. Once the reader nonspinnable bit is on, it will only be reset when a writer is able to acquire the rwsem in the fast path or somehow a reader or writer in the slowpath doesn't observe the nonspinable bit. This is to discourage reader optmistic spinning on that particular rwsem and make writers more preferred. This adaptive disabling of reader optimistic spinning will alleviate some of the negative side effect of this feature. In addition, this patch tries to make readers in the spinning queue follow the phase-fair principle after quitting optimistic spinning by checking if another reader has somehow acquired a read lock after this reader enters the optimistic spinning queue. If so and the rwsem is still reader-owned, this reader is in the right read-phase and can attempt to acquire the lock. On a 2-socket 40-core 80-thread Skylake system, the page_fault1 test of the will-it-scale benchmark was run with various number of threads. The number of operations done before reader optimistic spinning patches, this patch and after this patch were: Threads Before rspin Before patch After patch %change ------- ------------ ------------ ----------- ------- 20 5541068 5345484 5455667 -3.5%/ +2.1% 40 10185150 7292313 9219276 -28.5%/+26.4% 60 8196733 6460517 7181209 -21.2%/+11.2% 80 9508864 6739559 8107025 -29.1%/+20.3% This patch doesn't recover all the lost performance, but it is more than half. Given the fact that reader optimistic spinning does benefit some workloads, this is a good compromise. Using the rwsem locking microbenchmark with very short critical section, this patch doesn't have too much impact on locking performance as shown by the locking rates (kops/s) below with equal numbers of readers and writers before and after this patch: # of Threads Pre-patch Post-patch ------------ --------- ---------- 2 4,730 4,969 4 4,814 4,786 8 4,866 4,815 16 4,715 4,511 32 3,338 3,500 64 3,212 3,389 80 3,110 3,044 When running the locking microbenchmark with 40 dedicated reader and writer threads, however, the reader performance is curtailed to favor the writer.

Waiman Long	7d43f1ce9d	locking/rwsem: Enable time-based spinning on reader-owned rwsem ... When the rwsem is owned by reader, writers stop optimistic spinning simply because there is no easy way to figure out if all the readers are actively running or not. However, there are scenarios where the readers are unlikely to sleep and optimistic spinning can help performance. This patch provides a simple mechanism for spinning on a reader-owned rwsem by a writer. It is a time threshold based spinning where the allowable spinning time can vary from 10us to 25us depending on the condition of the rwsem. When the time threshold is exceeded, the nonspinnable bits will be set in the owner field to indicate that no more optimistic spinning will be allowed on this rwsem until it becomes writer owned again. Not even readers is allowed to acquire the reader-locked rwsem by optimistic spinning for fairness. We also want a writer to acquire the lock after the readers hold the lock for a relatively long time. In order to give preference to writers under such a circumstance, the single RWSEM_NONSPINNABLE bit is now split into two - one for reader and one for writer. When optimistic spinning is disabled, both bits will be set. When the reader count drop down to 0, the writer nonspinnable bit will be cleared to allow writers to spin on the lock, but not the readers. When a writer acquires the lock, it will write its own task structure pointer into sem->owner and clear the reader nonspinnable bit in the process. The time taken for each iteration of the reader-owned rwsem spinning loop varies. Below are sample minimum elapsed times for 16 iterations of the loop. System Time for 16 Iterations ------ ---------------------- 1-socket Skylake ~800ns 4-socket Broadwell ~300ns 2-socket ThunderX2 (arm64) ~250ns When the lock cacheline is contended, we can see up to almost 10X increase in elapsed time. So 25us will be at most 500, 1300 and 1600 iterations for each of the above systems. With a locking microbenchmark running on 5.1 based kernel, the total locking rates (in kops/s) on a 8-socket IvyBridge-EX system with equal numbers of readers and writers before and after this patch were as follows: # of Threads Pre-patch Post-patch ------------ --------- ---------- 2 1,759 6,684 4 1,684 6,738 8 1,074 7,222 16 900 7,163 32 458 7,316 64 208 520 128 168 425 240 143 474 This patch gives a big boost in performance for mixed reader/writer workloads. With 32 locking threads, the rwsem lock event data were: rwsem_opt_fail=79850 rwsem_opt_nospin=5069 rwsem_opt_rlock=597484 rwsem_opt_wlock=957339 rwsem_sleep_reader=57782 rwsem_sleep_writer=55663 With 64 locking threads, the data looked like: rwsem_opt_fail=346723 rwsem_opt_nospin=6293 rwsem_opt_rlock=1127119 rwsem_opt_wlock=1400628 rwsem_sleep_reader=308201 rwsem_sleep_writer=72281 So a lot more threads acquired the lock in the slowpath and more threads went to sleep.

Waiman Long	02f1082b00	locking/rwsem: Clarify usage of owner's nonspinaable bit ... Bit 1 of sem->owner (RWSEM_ANONYMOUSLY_OWNED) is used to designate an anonymous owner - readers or an anonymous writer. The setting of this anonymous bit is used as an indicator that optimistic spinning cannot be done on this rwsem. With the upcoming reader optimistic spinning patches, a reader-owned rwsem can be spinned on for a limit period of time. We still need this bit to indicate a rwsem is nonspinnable, but not setting this bit loses its meaning that the owner is known. So rename the bit to RWSEM_NONSPINNABLE to clarify its meaning.

Waiman Long	d3681e269f	locking/rwsem: Wake up almost all readers in wait queue ... When the front of the wait queue is a reader, other readers immediately following the first reader will also be woken up at the same time. However, if there is a writer in between. Those readers behind the writer will not be woken up. Because of optimistic spinning, the lock acquisition order is not FIFO anyway. The lock handoff mechanism will ensure that lock starvation will not happen. Assuming that the lock hold times of the other readers still in the queue will be about the same as the readers that are being woken up, there is really not much additional cost other than the additional latency due to the wakeup of additional tasks by the waker. Therefore all the readers up to a maximum of 256 in the queue are woken up when the first waiter is a reader to improve reader throughput. This is somewhat similar in concept to a phase-fair R/W lock. With a locking microbenchmark running on 5.1 based kernel, the total locking rates (in kops/s) on a 8-socket IvyBridge-EX system with equal numbers of readers and writers before and after this patch were as follows: # of Threads Pre-Patch Post-patch ------------ --------- ---------- 4 1,641 1,674 8 731 1,062 16 564 924 32 78 300 64 38 195 240 50 149 There is no performance gain at low contention level.

Waiman Long	990fa7384a	locking/rwsem: More optimal RT task handling of null owner ... An RT task can do optimistic spinning only if the lock holder is actually running. If the state of the lock holder isn't known, there is a possibility that high priority of the RT task may block forward progress of the lock holder if it happens to reside on the same CPU. This will lead to deadlock. So we have to make sure that an RT task will not spin on a reader-owned rwsem. When the owner is temporarily set to NULL, there are two cases where we may want to continue spinning: 1) The lock owner is in the process of releasing the lock, sem->owner is cleared but the lock has not been released yet. 2) The lock was free and owner cleared, but another task just comes in and acquire the lock before we try to get it. The new owner may be a spinnable writer. So an RT task is now made to retry one more time to see if it can acquire the lock or continue spinning on the new owning writer. When testing on a 8-socket IvyBridge-EX system, the one additional retry seems to improve locking performance of RT write locking threads under heavy contentions. The table below shows the locking rates (in kops/s) with various write locking threads before and after the patch.

Waiman Long	00f3c5a3df	locking/rwsem: Always release wait_lock before waking up tasks ... With the use of wake_q, we can do task wakeups without holding the wait_lock. There is one exception in the rwsem code, though. It is when the writer in the slowpath detects that there are waiters ahead but the rwsem is not held by a writer. This can lead to a long wait_lock hold time especially when a large number of readers are to be woken up. Remediate this situation by releasing the wait_lock before waking up tasks and re-acquiring it afterward. The rwsem_try_write_lock() function is also modified to read the rwsem count directly to avoid stale count value.
