cleared" This reverts commit c46bfba1337d ("connector: Fix proc_event_num_listeners count not cleared"). It is not accurate to reset proc_event_num_listeners according to cn_netlink_send_mult() return value -ESRCH. In the case of stress-ng netlink-proc, -ESRCH will always be returned, because netlink_broadcast_filtered will return -ESRCH, which may cause stress-ng netlink-proc performance degradation.

2024-02-13irqchip/loongson-eiointc: Use correct struct type in eiointc_domain_alloc()Bibo Mao
eiointc_domain_alloc() uses struct eiointc, which is not defined, for a pointer. Older compilers treat that as a forward declaration and due to assignment of a void pointer there is no warning emitted. As the variable is then handed in as a void pointer argument to irq_domain_set_info() the code is functional. Use struct eiointc_priv instead.

2024-02-13xen/events: close evtchn after mapping cleanupMaximilian Heyne
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: stable@vger.kernel.org Co-debugged-by: Andrew Panyakin <apanyaki@amazon.com> Signed-off-by: Maximilian Heyne <mheyne@amazon.de> Reviewed-by: Juergen Gross <jgross@suse.com> Link: https://lore.kernel.org/r/20240124163130.31324-1-mheyne@amazon.de Signed-off-by: Juergen Gross <jgross@suse.com>
2024-02-13irqchip/irq-brcmstb-l2: Add write memory barrier before exitDoug Berger
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.

2024-02-12net: stmmac: xgmac: use #define for string constantsSimon Horman
The cited commit introduces and uses the string constants dpp_tx_err and dpp_rx_err. These are assigned to constant fields of the array dwxgmac3_error_desc. It has been reported that on GCC 6 and 7.5.0 this results in warnings such as: .../dwxgmac2_core.c:836:20: error: initialiser element is not constant { true, "TDPES0", dpp_tx_err }, I have been able to reproduce this using: GCC 7.5.0, 8.4.0, 9.4.0 and 10.5.0. But not GCC 13.2.0. So it seems this effects older compilers but not newer ones. As Jon points out in his report, the minimum compiler supported by the kernel is GCC 5.1, so it does seem that this ought to be fixed. It is not clear to me what combination of 'const', if any, would address this problem. So this patch takes of using #defines for the string constants Compile tested only.

2024-02-12i2c: qcom-geni: Correct I2C TRE sequenceViken Dadhaniya
For i2c read operation in GSI mode, we are getting timeout due to malformed TRE basically incorrect TRE sequence in gpi(drivers/dma/qcom/gpi.c) driver. I2C driver has geni_i2c_gpi(I2C_WRITE) function which generates GO TRE and geni_i2c_gpi(I2C_READ)generates DMA TRE. Hence to generate GO TRE before DMA TRE, we should move geni_i2c_gpi(I2C_WRITE) before geni_i2c_gpi(I2C_READ) inside the I2C GSI mode transfer function i.e. geni_i2c_gpi_xfer(). TRE stands for Transfer Ring Element - which is basically an element with size of 4 words. It contains all information like slave address, clk divider, dma address value data size etc). Mainly we have 3 TREs(Config, GO and DMA tre). - CONFIG TRE : consists of internal register configuration which is required before start of the transfer. - DMA TRE : contains DDR/Memory address, called as DMA descriptor. - GO TRE : contains Transfer directions, slave ID, Delay flags, Length of the transfer. I2c driver calls GPI driver API to config each TRE depending on the protocol. For read operation tre sequence will be as below which is not aligned to hardware programming guide. - CONFIG tre - DMA tre - GO tre As per Qualcomm's internal Hardware Programming Guide, we should configure TREs in below sequence for any RX only transfer. - CONFIG tre - GO tre - DMA tre Fixes: d8703554f4de ("i2c: qcom-geni: Add support for GPI DMA") Reviewed-by: Andi Shyti <andi.shyti@kernel.org> Reviewed-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org> Tested-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org> # qrb5165-rb5 Co-developed-by: Mukesh Kumar Savaliya <quic_msavaliy@quicinc.com> Signed-off-by: Mukesh Kumar Savaliya <quic_msavaliy@quicinc.com> Signed-off-by: Viken Dadhaniya <quic_vdadhani@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Signed-off-by: Andi Shyti <andi.shyti@kernel.org>

2024-02-12regmap: kunit: Ensure that changed bytes are actually differentMark Brown
During the cache sync test we verify that values we expect to have been written only to the cache do not appear in the hardware. This works most of the time but since we randomly generate both the original and new values there is a low probability that these values may actually be the same. Wrap get_random_bytes() to ensure that the values are different, there are other tests which should have similar verification that we actually changed something. While we're at it refactor the test to use three changed values rather than attempting to use one of them twice, that just complicates checking that our new values are actually new. We use random generation to try to avoid data dependencies in the tests.

2024-02-12drm/nouveau: don't fini scheduler if not initializedDanilo Krummrich
nouveau_abi16_ioctl_channel_alloc() and nouveau_cli_init() simply call their corresponding *_fini() counterpart. This can lead to nouveau_sched_fini() being called without struct nouveau_sched ever being initialized in the first place. Instead of embedding struct nouveau_sched into struct nouveau_cli and struct nouveau_chan_abi16, allocate struct nouveau_sched separately, such that we can check for the corresponding pointer to be NULL in the particular *_fini() functions. It makes sense to allocate struct nouveau_sched separately anyway, since in a subsequent commit we can also avoid to allocate a struct nouveau_sched in nouveau_abi16_ioctl_channel_alloc() at all, if the VM_BIND uAPI has been disabled due to the legacy uAPI being used.

2024-02-12drm/i915/dsc: Fix the macro that calculates DSCC_/DSCA_ PPS reg addressManasi Navare
Commit bd077259d0a9 ("drm/i915/vdsc: Add function to read any PPS register") defines a new macro to calculate the DSC PPS register addresses with PPS number as an input. This macro correctly calculates the addresses till PPS 11 since the addresses increment by 4. So in that case the following macro works correctly to give correct register address: _MMIO(_DSCA_PPS_0 + (pps) * 4) However after PPS 11, the register address for PPS 12 increments by 12 because of RC Buffer memory allocation in between. Because of this discontinuity in the address space, the macro calculates wrong addresses for PPS 12 - 16 resulting into incorrect DSC PPS parameter value read/writes causing DSC corruption. This fixes it by correcting this macro to add the offset of 12 for PPS >=12. v3: Add correct paranthesis for pps argument (Jani Nikula) Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/10172 Fixes: bd077259d0a9 ("drm/i915/vdsc: Add function to read any PPS register") Cc: Suraj Kandpal <suraj.kandpal@intel.com> Cc: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Cc: Animesh Manna <animesh.manna@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Sean Paul <sean@poorly.run> Cc: Drew Davenport <ddavenport@chromium.org> Signed-off-by: Manasi Navare <navaremanasi@chromium.org> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240205204619.1991673-1-navaremanasi@chromium.org (cherry picked from commit 6074be620c31dc2ae11af96a1a5ea95580976fb5) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>

Issue IP reset before shutdown in order to complete all upstream requests to the SOC. Without this DevTLB is complaining about incomplete transactions and NPU cannot resume from suspend. This problem is only happening on recent IFWI releases. IP reset in rare corner cases can mess up PCI configuration, so save it before the reset. After this happens it is also impossible to issue PLL requests and D0->D3->D0 cycle is needed to recover the NPU. Add WP 0 request on power up, so the PUNIT is always notified about NPU reset. Use D0/D3 cycle for recovery as it can recover from failed IP reset and FLR cannot.

git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire fix from Takashi Sakamoto: "A change to accelerate the device detection step in some cases. In the self-identification step after bus-reset, all nodes in the same bus broadcast selfID packet including the value of gap count. The value is related to the cable hops between nodes, and used to calculate the subaction gap and the arbitration reset gap. When each node has the different value of the gap count, the asynchronous communication between them is unreliable, since an asynchronous transaction could be interrupted by another asynchronous transaction before completion. The gap count inconsistency can be resolved by several ways; e.g. the transfer of PHY configuration packet and generation of bus-reset. The current implementation of firewire stack can correctly detect the gap count inconsistency, however the recovery action from the inconsistency tends to be delayed after reading configuration ROM of root node. This results in the long time to probe devices in some combinations of hardware. Here the stack is changed to schedule the action as soon as possible" * tag 'firewire-fixes-6.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: firewire: core: send bus reset promptly on gap count error

2024-02-09lan966x: Fix crash when adding interface under a lagHoratiu Vultur
There is a crash when adding one of the lan966x interfaces under a lag interface. The issue can be reproduced like this: ip link add name bond0 type bond miimon 100 mode balance-xor ip link set dev eth0 master bond0 The reason is because when adding a interface under the lag it would go through all the ports and try to figure out which other ports are under that lag interface. And the issue is that lan966x can have ports that are NULL pointer as they are not probed. So then iterating over these ports it would just crash as they are NULL pointers. The fix consists in actually checking for NULL pointers before accessing something from the ports. Like we do in other places.

2024-02-09PCI: Fix active state requirement in PME pollingAlex Williamson
The commit noted in fixes added a bogus requirement that runtime PM managed devices need to be in the RPM_ACTIVE state for PME polling. In fact, only devices in low power states should be polled. However there's still a requirement that the device config space must be accessible, which has implications for both the current state of the polled device and the parent bridge, when present. It's not sufficient to assume the bridge remains in D0 and cases have been observed where the bridge passes the D0 test, but the PM state indicates RPM_SUSPENDING and config space of the polled device becomes inaccessible during pci_pme_wakeup(). Therefore, since the bridge is already effectively required to be in the RPM_ACTIVE state, formalize this in the code and elevate the PM usage count to maintain the state while polling the subordinate device. This resolves a regression reported in the bugzilla below where a Thunderbolt/USB4 hierarchy fails to scan for an attached NVMe endpoint downstream of a bridge in a D3hot power state.
