Tetsuo Handa	c71ec39be4	workqueue: don't skip lockdep work dependency in cancel_work_sync() ... [ Upstream commit c0feea594e058223973db94c1c32a830c9807c86 ] Like Hillf Danton mentioned syzbot should have been able to catch cancel_work_sync() in work context by checking lockdep_map in __flush_work() for both flush and cancel. in [1], being unable to report an obvious deadlock scenario shown below is broken. From locking dependency perspective, sync version of cancel request should behave as if flush request, for it waits for completion of work if that work has already started execution. ---------- #include <linux/module.h> #include <linux/sched.h> static DEFINE_MUTEX(mutex); static void work_fn(struct work_struct *work) { schedule_timeout_uninterruptible(HZ / 5); mutex_lock(&mutex); mutex_unlock(&mutex); } static DECLARE_WORK(work, work_fn); static int __init test_init(void) { schedule_work(&work); schedule_timeout_uninterruptible(HZ / 10); mutex_lock(&mutex); cancel_work_sync(&work); mutex_unlock(&mutex); return -EINVAL; } module_init(test_init); MODULE_LICENSE("GPL"); ---------- The check this patch restores was added by commit 0976dfc1d0 ("workqueue: Catch more locking problems with flush_work()"). Then, lockdep's crossrelease feature was added by commit b09be676e0 ("locking/lockdep: Implement the 'crossrelease' feature"). As a result, this check was once removed by commit fd1a5b04df ("workqueue: Remove now redundant lock acquisitions wrt. workqueue flushes"). But lockdep's crossrelease feature was removed by commit e966eaeeb6 ("locking/lockdep: Remove the cross-release locking checks"). At this point, this check should have been restored. Then, commit d6e89786be ("workqueue: skip lockdep wq dependency in cancel_work_sync()") introduced a boolean flag in order to distinguish flush_work() and cancel_work_sync(), for checking "struct workqueue_struct" dependency when called from cancel_work_sync() was causing false positives. Then, commit 87915adc3f ("workqueue: re-add lockdep dependencies for flushing") tried to restore "struct work_struct" dependency check, but by error checked this boolean flag. Like an example shown above indicates, "struct work_struct" dependency needs to be checked for both flush_work() and cancel_work_sync().

Marco Elver	507128e800	UPSTREAM: workqueue, kasan: avoid alloc_pages() when recording stack ... Shuah Khan reported: | When CONFIG_PROVE_RAW_LOCK_NESTING=y and CONFIG_KASAN are enabled, | kasan_record_aux_stack() runs into "BUG: Invalid wait context" when | it tries to allocate memory attempting to acquire spinlock in page | allocation code while holding workqueue pool raw_spinlock. | | There are several instances of this problem when block layer tries | to __queue_work(). Call trace from one of these instances is below: | | kblockd_mod_delayed_work_on() | mod_delayed_work_on() | __queue_delayed_work() | __queue_work() (rcu_read_lock, raw_spin_lock pool->lock held) | insert_work() | kasan_record_aux_stack() | kasan_save_stack() | stack_depot_save() | alloc_pages() | __alloc_pages() | get_page_from_freelist() | rm_queue() | rm_queue_pcplist() | local_lock_irqsave(&pagesets.lock, flags); | [ BUG: Invalid wait context triggered ] The default kasan_record_aux_stack() calls stack_depot_save() with GFP_NOWAIT, which in turn can then call alloc_pages(GFP_NOWAIT, ...). In general, however, it is not even possible to use either GFP_ATOMIC nor GFP_NOWAIT in certain non-preemptive contexts, including raw_spin_locks (see gfp.h and commmit ab00db216c). Fix it by instructing stackdepot to not expand stack storage via alloc_pages() in case it runs out by using kasan_record_aux_stack_noalloc(). While there is an increased risk of failing to insert the stack trace, this is typically unlikely, especially if the same insertion had already succeeded previously (stack depot hit). For frequent calls from the same location, it therefore becomes extremely unlikely that kasan_record_aux_stack_noalloc() fails.

Frederic Weisbecker	cf5b6bd2c7	workqueue: Fix unbind_workers() VS wq_worker_running() race ... commit 07edfece8bcb0580a1828d939e6f8d91a8603eb2 upstream. At CPU-hotplug time, unbind_worker() may preempt a worker while it is waking up. In that case the following scenario can happen: unbind_workers() wq_worker_running() -------------- ------------------- if (!(worker->flags & WORKER_NOT_RUNNING)) //PREEMPTED by unbind_workers worker->flags |= WORKER_UNBOUND; [...] atomic_set(&pool->nr_running, 0); //resume to worker atomic_inc(&worker->pool->nr_running); After unbind_worker() resets pool->nr_running, the value is expected to remain 0 until the pool ever gets rebound in case cpu_up() is called on the target CPU in the future. But here the race leaves pool->nr_running with a value of 1, triggering the following warning when the worker goes idle: WARNING: CPU: 3 PID: 34 at kernel/workqueue.c:1823 worker_enter_idle+0x95/0xc0 Modules linked in: CPU: 3 PID: 34 Comm: kworker/3:0 Not tainted 5.16.0-rc1+ #34 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.12.0-59-gc9ba527-rebuilt.opensuse.org 04/01/2014 Workqueue: 0x0 (rcu_par_gp) RIP: 0010:worker_enter_idle+0x95/0xc0 Code: 04 85 f8 ff ff ff 39 c1 7f 09 48 8b 43 50 48 85 c0 74 1b 83 e2 04 75 99 8b 43 34 39 43 30 75 91 8b 83 00 03 00 00 85 c0 74 87 <0f> 0b 5b c3 48 8b 35 70 f1 37 01 48 8d 7b 48 48 81 c6 e0 93 0 RSP: 0000:ffff9b7680277ed0 EFLAGS: 00010086 RAX: 00000000ffffffff RBX: ffff93465eae9c00 RCX: 0000000000000000 RDX: 0000000000000000 RSI: ffff9346418a0000 RDI: ffff934641057140 RBP: ffff934641057170 R08: 0000000000000001 R09: ffff9346418a0080 R10: ffff9b768027fdf0 R11: 0000000000002400 R12: ffff93465eae9c20 R13: ffff93465eae9c20 R14: ffff93465eae9c70 R15: ffff934641057140 FS: 0000000000000000(0000) GS:ffff93465eac0000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 000000001cc0c000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: <TASK> worker_thread+0x89/0x3d0 ? process_one_work+0x400/0x400 kthread+0x162/0x190 ? set_kthread_struct+0x40/0x40 ret_from_fork+0x22/0x30 </TASK> Also due to this incorrect "nr_running == 1", further queued work may end up not being served, because no worker is awaken at work insert time. This raises rcutorture writer stalls for example. Fix this with disabling preemption in the right place in wq_worker_running(). It's worth noting that if the worker migrates and runs concurrently with unbind_workers(), it is guaranteed to see the WORKER_UNBOUND flag update due to set_cpus_allowed_ptr() acquiring/releasing rq->lock.

Menglong Dong	b09a201b71	workqueue: make sysfs of unbound kworker cpumask more clever ... [ Upstream commit d25302e46592c97d29f70ccb1be558df31a9a360 ] Some unfriendly component, such as dpdk, write the same mask to unbound kworker cpumask again and again. Every time it write to this interface some work is queue to cpu, even though the mask is same with the original mask. So, fix it by return success and do nothing if the cpumask is equal with the old one.

Johan Hovold	57116ce17b	workqueue: fix state-dump console deadlock ... Console drivers often queue work while holding locks also taken in their console write paths, something which can lead to deadlocks on SMP when dumping workqueue state (e.g. sysrq-t or on suspend failures). For serial console drivers this could look like: CPU0 CPU1 ---- ---- show_workqueue_state(); lock(&pool->lock); <IRQ> lock(&port->lock); schedule_work(); lock(&pool->lock); printk(); lock(console_owner); lock(&port->lock); where workqueues are, for example, used to push data to the line discipline, process break signals and handle modem-status changes. Line disciplines and serdev drivers can also queue work on write-wakeup notifications, etc. Reworking every console driver to avoid queuing work while holding locks also taken in their write paths would complicate drivers and is neither desirable or feasible. Instead use the deferred-printk mechanism to avoid printing while holding pool locks when dumping workqueue state. Note that there are a few WARN_ON() assertions in the workqueue code which could potentially also trigger a deadlock. Hopefully the ongoing printk rework will provide a general solution for this eventually. This was originally reported after a lockdep splat when executing sysrq-t with the imx serial driver.

Lai Jiangshan	d812796eb3	workqueue: Assign a color to barrier work items ... There was no strong reason to or not to flush barrier work items in flush_workqueue(). And we have to make barrier work items not participate in nr_active so we had been using WORK_NO_COLOR for them which also makes them can't be flushed by flush_workqueue(). And the users of flush_workqueue() often do not intend to wait barrier work items issued by flush_work(). That made the choice sound perfect. But barrier work items have reference to internal structure (pool_workqueue) and the worker thread[s] is/are still busy for the workqueue user when the barrrier work items are not done. So it is reasonable to make flush_workqueue() also watch for flush_work() to make it more robust. And a problem[1] reported by Li Zhe shows that we need such robustness. The warning logs are listed below: WARNING: CPU: 0 PID: 19336 at kernel/workqueue.c:4430 destroy_workqueue+0x11a/0x2f0 ***** destroy_workqueue: test_workqueue9 has the following busy pwq pwq 4: cpus=2 node=0 flags=0x0 nice=0 active=0/1 refcnt=2 in-flight: 5658:wq_barrier_func Showing busy workqueues and worker pools: ***** It shows that even after drain_workqueue() returns, the barrier work item is still in flight and the pwq (and a worker) is still busy on it. The problem is caused by flush_workqueue() not watching flush_work(): Thread A Worker /* normal work item with linked */ process_scheduled_works() destroy_workqueue() process_one_work() drain_workqueue() /* run normal work item */ /-- pwq_dec_nr_in_flight() flush_workqueue() <---/ /* the last normal work item is done */ sanity_check process_one_work() /-- raw_spin_unlock_irq(&pool->lock) raw_spin_lock_irq(&pool->lock) <-/ /* maybe preempt */ *WARNING* wq_barrier_func() /* maybe preempt by cond_resched() */ Thread A can get the pool lock after the Worker unlocks the pool lock before running wq_barrier_func(). And if there is any preemption happen around wq_barrier_func(), destroy_workqueue()'s sanity check is more likely to get the lock and catch it. (Note: preemption is not necessary to cause the bug, the unlocking is enough to possibly trigger the WARNING.) A simple solution might be just executing all linked barrier work items once without releasing pool lock after the head work item's pwq_dec_nr_in_flight(). But this solution has two problems: 1) the head work item might also be barrier work item when the user-queued work item is cancelled. For example: thread 1: thread 2: queue_work(wq, &my_work) flush_work(&my_work) cancel_work_sync(&my_work); /* Neiter my_work nor the barrier work is scheduled. */ destroy_workqueue(wq); /* This is an easier way to catch the WARNING. */ 2) there might be too much linked barrier work items and running them all once without releasing pool lock just causes trouble. The only solution is to make flush_workqueue() aslo watch barrier work items. So we have to assign a color to these barrier work items which is the color of the head (user-queued) work item. Assigning a color doesn't cause any problem in ative management, because the prvious patch made barrier work items not participate in nr_active via WORK_STRUCT_INACTIVE rather than reliance on the (old) WORK_NO_COLOR.

Lai Jiangshan	018f3a13dd	workqueue: Mark barrier work with WORK_STRUCT_INACTIVE ... Currently, WORK_NO_COLOR has two meanings: Not participate in flushing Not participate in nr_active And only non-barrier work items are marked with WORK_STRUCT_INACTIVE when they are in inactive_works list. The barrier work items are not marked INACTIVE even linked in inactive_works list since these tail items are always moved together with the head work item. These definitions are simple, clean and practical. (Except a small blemish that only the first meaning of WORK_NO_COLOR is documented in include/linux/workqueue.h while both meanings are in workqueue.c) But dual-purpose WORK_NO_COLOR used for barrier work items has proven to be problematical[1]. Only the second purpose is obligatory. So we plan to make barrier work items participate in flushing but keep them still not participating in nr_active. So the plan is to mark barrier work items inactive without using WORK_NO_COLOR in this patch so that we can assign a flushing color to them in next patch. The reasonable way is to add or reuse a bit in work data of the work item. But adding a bit will double the size of pool_workqueue. Currently, WORK_STRUCT_INACTIVE is only used in try_to_grab_pending() for user-queued work items and try_to_grab_pending() can't work for barrier work items. So we extend WORK_STRUCT_INACTIVE to also mark barrier work items no matter which list they are in because we don't need to determind which list a barrier work item is in. So the meaning of WORK_STRUCT_INACTIVE becomes just "the work items don't participate in nr_active" (no matter whether it is a barrier work item or a user-queued work item). And WORK_STRUCT_INACTIVE for user-queued work items means they are in inactive_works list. This patch does it by setting WORK_STRUCT_INACTIVE for barrier work items in insert_wq_barrier() and checking WORK_STRUCT_INACTIVE first in pwq_dec_nr_in_flight(). And the meaning of WORK_NO_COLOR is reduced to only "not participating in flushing". There is no functionality change intended in this patch. Because WORK_NO_COLOR+WORK_STRUCT_INACTIVE represents the previous WORK_NO_COLOR in meaning and try_to_grab_pending() doesn't use for barrier work items and avoids being confused by this extended WORK_STRUCT_INACTIVE. A bunch of comment for nr_active & WORK_STRUCT_INACTIVE is also added for documenting how WORK_STRUCT_INACTIVE works in nr_active management.

Lai Jiangshan	f97a4a1a3f	workqueue: Rename "delayed" (delayed by active management) to "inactive" ... There are two kinds of "delayed" work items in workqueue subsystem. One is for timer-delayed work items which are visible to workqueue users. The other kind is for work items delayed by active management which can not be directly visible to workqueue users. We mixed the word "delayed" for both kinds and caused somewhat ambiguity. This patch renames the later one (delayed by active management) to "inactive", because it is used for workqueue active management and most of its related symbols are named with "active" or "activate". All "delayed" and "DELAYED" are carefully checked and renamed one by one to avoid accidentally changing the name of the other kind for timer-delayed. No functional change intended.

Wang Qing	89e28ce60c	workqueue/watchdog: Make unbound workqueues aware of touch_softlockup_watchdog() ... 84;0;0c84;0;0c There are two workqueue-specific watchdog timestamps: + @wq_watchdog_touched_cpu (per-CPU) updated by touch_softlockup_watchdog() + @wq_watchdog_touched (global) updated by touch_all_softlockup_watchdogs() watchdog_timer_fn() checks only the global @wq_watchdog_touched for unbound workqueues. As a result, unbound workqueues are not aware of touch_softlockup_watchdog(). The watchdog might report a stall even when the unbound workqueues are blocked by a known slow code. Solution: touch_softlockup_watchdog() must touch also the global @wq_watchdog_touched timestamp. The global timestamp can no longer be used for bound workqueues because it is now updated from all CPUs. Instead, bound workqueues have to check only @wq_watchdog_touched_cpu and these timestamps have to be updated for all CPUs in touch_all_softlockup_watchdogs(). Beware: The change might cause the opposite problem. An unbound workqueue might get blocked on CPU A because of a real softlockup. The workqueue watchdog would miss it when the timestamp got touched on CPU B. It is acceptable because softlockups are detected by softlockup watchdog. The workqueue watchdog is there to detect stalls where a work never finishes, for example, because of dependencies of works queued into the same workqueue.

The scheduler won't break affinity for us any more, and we should "emulate" the same behavior when the scheduler breaks affinity for us. The behavior is "changing the cpumask to cpu_possible_mask". And there might be some other CPUs online later while the worker is still running with the pending work items. The worker should be allowed to use the later online CPUs as before and process the work items ASAP. If we use cpu_active_mask here, we can't achieve this goal but using cpu_possible_mask can.

Walter Wu	e89a85d63f	workqueue: kasan: record workqueue stack ... Patch series "kasan: add workqueue stack for generic KASAN", v5. Syzbot reports many UAF issues for workqueue, see [1]. In some of these access/allocation happened in process_one_work(), we see the free stack is useless in KASAN report, it doesn't help programmers to solve UAF for workqueue issue. This patchset improves KASAN reports by making them to have workqueue queueing stack. It is useful for programmers to solve use-after-free or double-free memory issue. Generic KASAN also records the last two workqueue stacks and prints them in KASAN report. It is only suitable for generic KASAN. [1] https://groups.google.com/g/syzkaller-bugs/search?q=%22use-after-free%22+process_one_work [2] https://bugzilla.kernel.org/show_bug.cgi?id=198437 This patch (of 4): When analyzing use-after-free or double-free issue, recording the enqueuing work stacks is helpful to preserve usage history which potentially gives a hint about the affected code. For workqueue it has turned out to be useful to record the enqueuing work call stacks. Because user can see KASAN report to determine whether it is root cause. They don't need to enable debugobjects, but they have a chance to find out the root cause.
