[for-next][PATCH 31/31] tracing/osnoise: Properly unhook events if start_per_cpu_kthreads() fails

by Steven Rostedt

From: Nikita Yushchenko <nikita.yushchenko(a)virtuozzo.com> If start_per_cpu_kthreads() called from osnoise_workload_start() returns error, event hooks are left in broken state: unhook_irq_events() called but unhook_thread_events() and unhook_softirq_events() not called, and trace_osnoise_callback_enabled flag not cleared. On the next tracer enable, hooks get not installed due to trace_osnoise_callback_enabled flag. And on the further tracer disable an attempt to remove non-installed hooks happened, hitting a WARN_ON_ONCE() in tracepoint_remove_func(). Fix the error path by adding the missing part of cleanup. While at this, introduce osnoise_unhook_events() to avoid code duplication between this error path and normal tracer disable.

[for-next][PATCH 14/31] tracing: Add test for user space strings when filtering on string pointers

[for-next][PATCH 13/31] tracing: Have syscall trace events use trace_event_buffer_lock_reserve()

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> Currently, the syscall trace events call trace_buffer_lock_reserve() directly, which means that it misses out on some of the filtering optimizations provided by the helper function trace_event_buffer_lock_reserve().

[PATCH resend v2] PCI: pciehp: Use down_read/write_nested(reset_lock) to fix lockdep errors

by Hans de Goede

Use down_read_nested() and down_write_nested() when taking the ctrl->reset_lock rw-sem, passing the number of PCIe hotplug controllers in the path to the PCI root bus as lock subclass parameter. This fixes the following false-positive lockdep report when unplugging a Lenovo X1C8 from a Lenovo 2nd gen TB3 dock: [ 28.583853] pcieport 0000:06:01.0: pciehp: Slot(1): Link Down [ 28.583891] pcieport 0000:06:01.0: pciehp: Slot(1): Card not present [ 28.584849] ============================================ [ 28.584854] WARNING: possible recursive locking detected [ 28.584858] 5.16.0-rc2+ #621 Not tainted [ 28.584864] -------------------------------------------- [ 28.584867] irq/124-pciehp/86 is trying to acquire lock: [ 28.584873] ffff8e5ac4299ef8 (&ctrl->reset_lock){.+.+}-{3:3}, at: pciehp_check_presence+0x23/0x80 [ 28.584904] but task is already holding lock: [ 28.584908] ffff8e5ac4298af8 (&ctrl->reset_lock){.+.+}-{3:3}, at: pciehp_ist+0xf3/0x180 [ 28.584929] other info that might help us debug this: [ 28.584933] Possible unsafe locking scenario: [ 28.584936] CPU0 [ 28.584939] ---- [ 28.584942] lock(&ctrl->reset_lock); [ 28.584949] lock(&ctrl->reset_lock); [ 28.584955] *** DEADLOCK *** [ 28.584959] May be due to missing lock nesting notation [ 28.584963] 3 locks held by irq/124-pciehp/86: [ 28.584970] #0: ffff8e5ac4298af8 (&ctrl->reset_lock){.+.+}-{3:3}, at: pciehp_ist+0xf3/0x180 [ 28.584991] #1: ffffffffa3b024e8 (pci_rescan_remove_lock){+.+.}-{3:3}, at: pciehp_unconfigure_device+0x31/0x110 [ 28.585012] #2: ffff8e5ac1ee2248 (&dev->mutex){....}-{3:3}, at: device_release_driver+0x1c/0x40 [ 28.585037] stack backtrace: [ 28.585042] CPU: 4 PID: 86 Comm: irq/124-pciehp Not tainted 5.16.0-rc2+ #621 [ 28.585052] Hardware name: LENOVO 20U90SIT19/20U90SIT19, BIOS N2WET30W (1.20 ) 08/26/2021 [ 28.585059] Call Trace: [ 28.585064] <TASK> [ 28.585073] dump_stack_lvl+0x59/0x73 [ 28.585087] __lock_acquire.cold+0xc5/0x2c6 [ 28.585106] ? find_held_lock+0x2b/0x80 [ 28.585124] lock_acquire+0xb5/0x2b0 [ 28.585132] ? pciehp_check_presence+0x23/0x80 [ 28.585144] ? lock_is_held_type+0xa8/0x120 [ 28.585161] down_read+0x3e/0x50 [ 28.585172] ? pciehp_check_presence+0x23/0x80 [ 28.585183] pciehp_check_presence+0x23/0x80 [ 28.585194] pciehp_runtime_resume+0x5c/0xa0 [ 28.585206] ? pci_msix_init+0x60/0x60 [ 28.585214] device_for_each_child+0x45/0x70 [ 28.585227] pcie_port_device_runtime_resume+0x20/0x30 [ 28.585236] pci_pm_runtime_resume+0xa7/0xc0 [ 28.585246] ? pci_pm_freeze_noirq+0x100/0x100 [ 28.585257] __rpm_callback+0x41/0x110 [ 28.585271] ? pci_pm_freeze_noirq+0x100/0x100 [ 28.585281] rpm_callback+0x59/0x70 [ 28.585293] rpm_resume+0x512/0x7b0 [ 28.585309] __pm_runtime_resume+0x4a/0x90 [ 28.585322] __device_release_driver+0x28/0x240 [ 28.585338] device_release_driver+0x26/0x40 [ 28.585351] pci_stop_bus_device+0x68/0x90 [ 28.585363] pci_stop_bus_device+0x2c/0x90 [ 28.585373] pci_stop_and_remove_bus_device+0xe/0x20 [ 28.585384] pciehp_unconfigure_device+0x6c/0x110 [ 28.585396] ? __pm_runtime_resume+0x58/0x90 [ 28.585409] pciehp_disable_slot+0x5b/0xe0 [ 28.585421] pciehp_handle_presence_or_link_change+0xc3/0x2f0 [ 28.585436] pciehp_ist+0x179/0x180 [ 28.585449] ? disable_irq_nosync+0x10/0x10 [ 28.585460] irq_thread_fn+0x1d/0x60 [ 28.585470] ? irq_thread+0x81/0x1a0 [ 28.585480] irq_thread+0xcb/0x1a0 [ 28.585491] ? irq_thread_fn+0x60/0x60 [ 28.585502] ? irq_thread_check_affinity+0xb0/0xb0 [ 28.585514] kthread+0x165/0x190 [ 28.585522] ? set_kthread_struct+0x40/0x40 [ 28.585531] ret_from_fork+0x1f/0x30 [ 28.585554] </TASK> This lockdep warning is triggered because with Thunderbolt, hotplug ports are nested. When removing multiple devices in a daisy-chain, each hotplug port's reset_lock may be acquired recursively. It's never the same lock, so the lockdep splat is a false positive. Because locks at the same hierarchy level are never acquired recursively, a per-level lockdep class is sufficient to fix the lockdep warning. The choice to use one lockdep subclass per pcie-hotplug controller in the path to the root-bus was made to conserve class keys because their number is limited and the complexity grows quadratically with number of keys according to Documentation/locking/lockdep-design.rst.
