Lockdep reports that acpi_nfit_shutdown() may deadlock against an
opportune acpi_nfit_scrub(). acpi_nfit_scrub () is run from inside a
'work' and therefore has already acquired workqueue-internal locks. It
also acquiires acpi_desc->init_mutex. acpi_nfit_shutdown() first
acquires init_mutex, and was subsequently attempting to cancel any
pending workqueue items. This reversed locking order causes a potential
deadlock:
======================================================
WARNING: possible circular locking dependency detected
6.2.0-rc3 #116 Tainted: G O N
------------------------------------------------------
libndctl/1958 is trying to acquire lock:
ffff888129b461c0 ((work_completion)(&(&acpi_desc->dwork)->work)){+.+.}-{0:0}, at: __flush_work+0x43/0x450
but task is already holding lock:
ffff888129b460e8 (&acpi_desc->init_mutex){+.+.}-{3:3}, at: acpi_nfit_shutdown+0x87/0xd0 [nfit]
which lock already depends on the new lock.
...
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(&acpi_desc->init_mutex);
lock((work_completion)(&(&acpi_desc->dwork)->work));
lock(&acpi_desc->init_mutex);
lock((work_completion)(&(&acpi_desc->dwork)->work));
*** DEADLOCK ***
Since the workqueue manipulation is protected by its own internal locking,
the cancellation of pending work doesn't need to be done under
acpi_desc->init_mutex. Move cancel_delayed_work_sync() outside the
init_mutex to fix the deadlock. Any work that starts after
acpi_nfit_shutdown() drops the lock will see ARS_CANCEL, and the
cancel_delayed_work_sync() will safely flush it out.

Enable the cpu v4 tests for LoongArch. Currently, we don't have BPF trampoline in LoongArch JIT, so the fentry test `test_ptr_struct_arg` still failed, will followup.

On sync reset reload work, when remote host updates devlink on reload actions performed on that host, it misses taking devlink lock before calling devlink_remote_reload_actions_performed() which results in triggering lock assert like the following: WARNING: CPU: 4 PID: 1164 at net/devlink/core.c:261 devl_assert_locked+0x3e/0x50 … CPU: 4 PID: 1164 Comm: kworker/u96:6 Tainted: G S W 6.10.0-rc2+ #116 Hardware name: Supermicro SYS-2028TP-DECTR/X10DRT-PT, BIOS 2.0 12/18/2015 Workqueue: mlx5_fw_reset_events mlx5_sync_reset_reload_work [mlx5_core] RIP: 0010:devl_assert_locked+0x3e/0x50 … Call Trace: <TASK> ? __warn+0xa4/0x210 ? devl_assert_locked+0x3e/0x50 ? report_bug+0x160/0x280 ? handle_bug+0x3f/0x80 ? exc_invalid_op+0x17/0x40 ? asm_exc_invalid_op+0x1a/0x20 ? devl_assert_locked+0x3e/0x50 devlink_notify+0x88/0x2b0 ? mlx5_attach_device+0x20c/0x230 [mlx5_core] ? __pfx_devlink_notify+0x10/0x10 ? process_one_work+0x4b6/0xbb0 process_one_work+0x4b6/0xbb0 […] Fixes: 84a433a ("net/mlx5: Lock mlx5 devlink reload callbacks") Signed-off-by: Moshe Shemesh <[email protected]> Reviewed-by: Maor Gottlieb <[email protected]> Signed-off-by: Tariq Toukan <[email protected]> Reviewed-by: Wojciech Drewek <[email protected]> Link: https://patch.msgid.link/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
