2024-02-13tracing: Use ring_buffer_record_is_set_on() in tracer_tracing_is_on()Sven Schnelle1-1/+1
tracer_tracing_is_on() checks whether record_disabled is not zero. This checks both the record_disabled counter and the RB_BUFFER_OFF flag. Reading the source it looks like this function should only check for the RB_BUFFER_OFF flag. Therefore use ring_buffer_record_is_set_on(). This fixes spurious fails in the 'test for function traceon/off triggers' test from the ftrace testsuite when the system is under load.

2024-02-13nvme: implement support for relaxed effectsKeith Busch2-0/+5
NVM Express TP4167 provides a way for controllers to report a relaxed execution constraint. Specifically, it notifies of exclusivity for IO vs. admin commands instead of grouping these together. If set, then we don't need to freeze IO in order to execute that admin command. The freezing distrupts IO processes, so it's nice to avoid that if the controller tells us it's not necessary.

2024-02-13ASoC: SOF: ipc4-pcm: Workaround for crashed firmware on system suspendPeter Ujfalusi1-1/+12
When the system is suspended while audio is active, the sof_ipc4_pcm_hw_free() is invoked to reset the pipelines since during suspend the DSP is turned off, streams will be re-started after resume. If the firmware crashes during while audio is running (or when we reset the stream before suspend) then the sof_ipc4_set_multi_pipeline_state() will fail with IPC error and the state change is interrupted. This will cause misalignment between the kernel and firmware state on next DSP boot resulting errors returned by firmware for IPC messages, eventually failing the audio resume. On stream close the errors are ignored so the kernel state will be corrected on the next DSP boot, so the second boot after the DSP panic. If sof_ipc4_trigger_pipelines() is called from sof_ipc4_pcm_hw_free() then state parameter is SOF_IPC4_PIPE_RESET and only in this case. Treat a forced pipeline reset similarly to how we treat a pcm_free by ignoring error on state sending to allow the kernel's state to be consistent with the state the firmware will have after the next boot.

2024-02-13HID: wacom: generic: Avoid reporting a serial of '0' to userspaceTatsunosuke Tobita1-1/+8
The xf86-input-wacom driver does not treat '0' as a valid serial number and will drop any input report which contains an MSC_SERIAL = 0 event. The kernel driver already takes care to avoid sending any MSC_SERIAL event if the value of serial[0] == 0 (which is the case for devices that don't actually report a serial number), but this is not quite sufficient. Only the lower 32 bits of the serial get reported to userspace, so if this portion of the serial is zero then there can still be problems. This commit allows the driver to report either the lower 32 bits if they are non-zero or the upper 32 bits otherwise.

2024-02-13af_unix: Fix task hung while purging oob_skb in GC.Kuniyuki Iwashima1-3/+4
syzbot reported a task hung; at the same time, GC was looping infinitely in list_for_each_entry_safe() for OOB skb. [0] syzbot demonstrated that the list_for_each_entry_safe() was not actually safe in this case. A single skb could have references for multiple sockets. If we free such a skb in the list_for_each_entry_safe(), the current and next sockets could be unlinked in a single iteration. unix_notinflight() uses list_del_init() to unlink the socket, so the prefetched next socket forms a loop itself and list_for_each_entry_safe() never stops. Here, we must use while() and make sure we always fetch the first socket.

2024-02-13HID: Intel-ish-hid: Ishtp: Fix sensor reads after ACPI S3 suspendEven Xu2-1/+5
After legacy suspend/resume via ACPI S3, sensor read operation fails with timeout. Also, it will cause delay in resume operation as there will be retries on failure. This is caused by commit f645a90e8ff7 ("HID: intel-ish-hid: ishtp-hid-client: use helper functions for connection"), which used helper functions to simplify connect, reset and disconnect process. Also avoid freeing and allocating client buffers again during reconnect process. But there is a case, when ISH firmware resets after ACPI S3 suspend, ishtp bus driver frees client buffers. Since there is no realloc again during reconnect, there are no client buffers available to send connection requests to the firmware. Without successful connection to the firmware, subsequent sensor reads will timeout. To address this issue, ishtp bus driver does not free client buffers on warm reset after S3 resume. Simply add the buffers from the read list to free list of buffers.

2024-02-13irqchip/gic-v3-its: Fix GICv4.1 VPE affinity updateMarc Zyngier1-9/+13
When updating the affinity of a VPE, the VMOVP command is currently skipped if the two CPUs are part of the same VPE affinity. But this is wrong, as the doorbell corresponding to this VPE is still delivered on the 'old' CPU, which screws up the balancing. Furthermore, offlining that 'old' CPU results in doorbell interrupts generated for this VPE being discarded. The harsh reality is that VMOVP cannot be elided when a set_affinity() request occurs. It needs to be obeyed, and if an optimisation is to be made, it is at the point where the affinity change request is made (such as in KVM). Drop the VMOVP elision altogether, and only use the vpe_table_mask to try and stay within the same ITS affinity group if at all possible.

2024-02-13irqchip/gic-v3-its: Restore quirk probing for ACPI-based systemsMarc Zyngier1-1/+2
While refactoring the way the ITSs are probed, the handling of quirks applicable to ACPI-based platforms was lost.

2024-02-13irqchip/gic-v3-its: Handle non-coherent GICv4 redistributorsMarc Zyngier1-12/+25
Although the GICv3 code base has gained some handling of systems failing to handle the shareability attributes, the GICv4 side of things has been firmly ignored. This is unfortunate, as the new recent addition of the "dma-noncoherent" is supposed to apply to all of the GICR tables, and not just the ones that are common to v3 and v4. Add some checks to handle the VPROPBASE/VPENDBASE shareability and cacheability attributes in the same way we deal with the other GICR_BASE registers, wrapping the flag check in a helper for improved readability. Note that this has been found by inspection only, as I don't have access to HW that suffers from this particular issue.

Functions rds_still_queued and rds_clear_recv_queue lock a given socket in order to safely iterate over the incoming rds messages. However calling rds_inc_put while under this lock creates a potential deadlock. rds_inc_put may eventually call rds_message_purge, which will lock m_rs_lock. This is the incorrect locking order since m_rs_lock is meant to be locked before the socket. To fix this, we move the message item to a local list or variable that wont need rs_recv_lock protection. Then we can safely call rds_inc_put on any item stored locally after rs_recv_lock is released.

2024-02-13xen/events: close evtchn after mapping cleanupMaximilian Heyne1-2/+6
shutdown_pirq and startup_pirq are not taking the irq_mapping_update_lock because they can't due to lock inversion. Both are called with the irq_desc->lock being taking. The lock order, however, is first irq_mapping_update_lock and then irq_desc->lock. This opens multiple races: - shutdown_pirq can be interrupted by a function that allocates an event channel: CPU0 CPU1 shutdown_pirq { xen_evtchn_close(e) __startup_pirq { EVTCHNOP_bind_pirq -> returns just freed evtchn e set_evtchn_to_irq(e, irq) } xen_irq_info_cleanup() { set_evtchn_to_irq(e, -1) } } Assume here event channel e refers here to the same event channel number. After this race the evtchn_to_irq mapping for e is invalid (-1). - __startup_pirq races with __unbind_from_irq in a similar way. Because __startup_pirq doesn't take irq_mapping_update_lock it can grab the evtchn that __unbind_from_irq is currently freeing and cleaning up. In this case even though the event channel is allocated, its mapping can be unset in evtchn_to_irq. The fix is to first cleanup the mappings and then close the event channel. In this way, when an event channel gets allocated it's potential previous evtchn_to_irq mappings are guaranteed to be unset already. This is also the reverse order of the allocation where first the event channel is allocated and then the mappings are setup. On a 5.10 kernel prior to commit 3fcdaf3d7634 ("xen/events: modify internal [un]bind interfaces"), we hit a BUG like the following during probing of NVMe devices. The issue is that during nvme_setup_io_queues, pci_free_irq is called for every device which results in a call to shutdown_pirq. With many nvme devices it's therefore likely to hit this race during boot because there will be multiple calls to shutdown_pirq and startup_pirq are running potentially in parallel. ------------[ cut here ]------------ blkfront: xvda: barrier or flush: disabled; persistent grants: enabled; indirect descriptors: enabled; bounce buffer: enabled kernel BUG at drivers/xen/events/events_base.c:499! invalid opcode: 0000 [#1] SMP PTI CPU: 44 PID: 375 Comm: kworker/u257:23 Not tainted 5.10.201-191.748.amzn2.x86_64 #1 Hardware name: Xen HVM domU, BIOS 4.11.amazon 08/24/2006 Workqueue: nvme-reset-wq nvme_reset_work RIP: 0010:bind_evtchn_to_cpu+0xdf/0xf0 Code: 5d 41 5e c3 cc cc cc cc 44 89 f7 e8 2b 55 ad ff 49 89 c5 48 85 c0 0f 84 64 ff ff ff 4c 8b 68 30 41 83 fe ff 0f 85 60 ff ff ff <0f> 0b 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 0f 1f 44 00 00 RSP: 0000:ffffc9000d533b08 EFLAGS: 00010046 RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000000000006 RDX: 0000000000000028 RSI: 00000000ffffffff RDI: 00000000ffffffff RBP: ffff888107419680 R08: 0000000000000000 R09: ffffffff82d72b00 R10: 0000000000000000 R11: 0000000000000000 R12: 00000000000001ed R13: 0000000000000000 R14: 00000000ffffffff R15: 0000000000000002 FS: 0000000000000000(0000) GS:ffff88bc8b500000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 0000000002610001 CR4: 00000000001706e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: ? show_trace_log_lvl+0x1c1/0x2d9 ? show_trace_log_lvl+0x1c1/0x2d9 ? set_affinity_irq+0xdc/0x1c0 ? __die_body.cold+0x8/0xd ? die+0x2b/0x50 ? do_trap+0x90/0x110 ? bind_evtchn_to_cpu+0xdf/0xf0 ? do_error_trap+0x65/0x80 ? bind_evtchn_to_cpu+0xdf/0xf0 ? exc_invalid_op+0x4e/0x70 ? bind_evtchn_to_cpu+0xdf/0xf0 ? asm_exc_invalid_op+0x12/0x20 ? bind_evtchn_to_cpu+0xdf/0xf0 ? bind_evtchn_to_cpu+0xc5/0xf0 set_affinity_irq+0xdc/0x1c0 irq_do_set_affinity+0x1d7/0x1f0 irq_setup_affinity+0xd6/0x1a0 irq_startup+0x8a/0xf0 __setup_irq+0x639/0x6d0 ? nvme_suspend+0x150/0x150 request_threaded_irq+0x10c/0x180 ? nvme_suspend+0x150/0x150 pci_request_irq+0xa8/0xf0 ? __blk_mq_free_request+0x74/0xa0 queue_request_irq+0x6f/0x80 nvme_create_queue+0x1af/0x200 nvme_create_io_queues+0xbd/0xf0 nvme_setup_io_queues+0x246/0x320 ? nvme_irq_check+0x30/0x30 nvme_reset_work+0x1c8/0x400 process_one_work+0x1b0/0x350 worker_thread+0x49/0x310 ? process_one_work+0x350/0x350 kthread+0x11b/0x140 ? __kthread_bind_mask+0x60/0x60 ret_from_fork+0x22/0x30 Modules linked in: ---[ end trace a11715de1eee1873 ]--- Fixes: d46a78b05c0e ("xen: implement pirq type event channels") Cc: [email protected] Co-debugged-by: Andrew Panyakin <[email protected]> Signed-off-by: Maximilian Heyne <[email protected]> Reviewed-by: Juergen Gross <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Juergen Gross <[email protected]>
2024-02-13irqchip/irq-brcmstb-l2: Add write memory barrier before exitDoug Berger1-1/+4
It was observed on Broadcom devices that use GIC v3 architecture L1 interrupt controllers as the parent of brcmstb-l2 interrupt controllers that the deactivation of the parent interrupt could happen before the brcmstb-l2 deasserted its output. This would lead the GIC to reactivate the interrupt only to find that no L2 interrupt was pending. The result was a spurious interrupt invoking handle_bad_irq() with its associated messaging. While this did not create a functional problem it is a waste of cycles. The hazard exists because the memory mapped bus writes to the brcmstb-l2 registers are buffered and the GIC v3 architecture uses a very efficient system register write to deactivate the interrupt. Add a write memory barrier prior to invoking chained_irq_exit() to introduce a dsb(st) on those systems to ensure the system register write cannot be executed until the memory mapped writes are visible to the system.

But not GCC 13.2.0. So it seems this effects older compilers but not newer ones.
