This stopped happening a while ago, let's close this to get

Since lockdep_unregister_key() becomes a no-op because graph_lock() returns 0
due to debug_locks being changed from 1 to 0 by __debug_locks_off() from
debug_locks_off() from debug_locks_off_graph_unlock(), lock-classes value in
/proc/lockdep_stats will not decrease after "BUG: MAX_LOCKDEP_KEYS too low!"
is printed.

Should not the first 8192 from "grep lock-classes /proc/lockdep_stats" 
decrease after time (it does not), or once it has failed, it is permanent?

Right. Hillf's patch can reduce number of active workqueue's worker threads, for
only one worker thread can call bpf_map_free_deferred() (which is nice because
it avoids bloat of active= and refcnt= fields). But Hillf's patch is not for
fixing the cause of "BUG: MAX_LOCKDEP_KEYS too low!" message.

Like Dmitry mentioned, bpf syscall allows producing work items faster than
bpf_map_free_deferred() can consume. (And a similar problem is observed for
network namespaces.) Unless there is a bug that prevents bpf_map_free_deferred()
 from completing, the classical solution is to put pressure on producers (i.e.
slow down bpf syscall side) in a way that consumers (i.e. __bpf_map_put())
will not schedule thousands of backlog "struct bpf_map" works.

this behaves quite different but still produces the message (i have

https://pastebin.com/JfrmzguK is with the patch below applied. Seems 
less output. Interestingly when I almost hit "send", OOM kicked in and 
tried killing a bunch of "maxlockdep" processes (my test case):

+netdev as it discusses net namespaces as well

Hi Alexey,

The reproducer only does 2 bpf syscalls, so something is slowly leaking in bpf.
My first suspect would be one of these. Since workqueue is async, it
may cause such slow drain that happens only when tasks are spawned
fast. I don't know if there is a procfs/debugfs introspection file to
monitor workqueue lengths to verify this hypothesis.

$ grep INIT_WORK kernel/bpf/*.c
kernel/bpf/arraymap.c: INIT_WORK(&aux->work, prog_array_map_clear_deferred);
kernel/bpf/cgroup.c: INIT_WORK(&cgrp->bpf.release_work, cgroup_bpf_release);
kernel/bpf/core.c: INIT_WORK(&aux->work, bpf_prog_free_deferred);
kernel/bpf/cpumap.c: INIT_WORK(&old_rcpu->kthread_stop_wq,
cpu_map_kthread_stop);
kernel/bpf/syscall.c: INIT_WORK(&map->work, bpf_map_free_deferred);
kernel/bpf/syscall.c: INIT_WORK(&link->work, bpf_link_put_deferred);

However, if it's indeed one of the workqueues, I am not sure how it
should be fixed.
We are having a similar (even worser) problem with async destruction
of network namespaces. These are way slower and take lots of mutexes.
I suspect that lots of hangs on net mutexes on syzbot dashboard are
related to that.

Unbounded async queueing is never a good idea. The classical solution
to this is to make the queue bounded and put back pressure on
producers. In this case it would limit the speed at which new
processes are created and make resource consumption (including # of
lockdep entries) bounded.
The restriction probably needs to be per-callback type, at least for
global workqueues.
However, I suspect that lots of callers of schedule_work can't block
(the reason for moving the work to background in the first place?). So
potentially the back pressure may be need to be applied at a different
point, which makes things a bit more complicated.

* BUG: MAX_LOCKDEP_KEYS too low!

Hi!

Syzkaller found this bug and it has a repro (below). I googled a similar 
bug in 2019 which was fixed so this seems new.

The repro takes about a half a minute to produce the message,  "grep 
lock-classes /proc/lockdep_stats" reports 8177 of 8192, before running 
the repro it is 702. It is a POWER8 box.

The offender is htab->lockdep_key. If I run repro at the slow rate, no 
problems appears, traces show lockdep_unregister_key() is called and the 
leak is quite slow.

Is this something known? Any hints how to debug this further? I'd give 
it a try since I have an easy reproducer. Thanks,



root@le-dbg:~# egrep "BD.*htab->lockdep_key" /proc/lockdep | wc -l
7449
root@le-dbg:~# egrep "BD.*htab->lockdep_key" /proc/lockdep | tail -n 3
