[PATCH] drm/xe/vram: fix ccs offset calculation

by Matthew Auld

Spec says SW is expected to round up to the nearest 128K, if not already aligned. We are seeing the assert sometimes pop on BMG to tell us that there is a hole between GSM and CCS, as well as popping other asserts with having a vram size with strange alignment, which is likely caused by misaligned offset here.

[PATCH v3] usb: gadget: core: force synchronous registration

Registering a gadget driver is expected to complete synchronously and immediately after calling driver_register() this function checks that the driver has bound so as to return an error.

FW: [PATCH] usb: xhci: fix loss of data on Cadence xHC

by Pawel Laszczak

Streams should flush their TRB cache, re-read TRBs, and start executing TRBs from the beginning of the new dequeue pointer after a 'Set TR Dequeue Pointer' command. Cadence controllers may fail to start from the beginning of the dequeue TRB as it doesn't clear the Opaque 'RsvdO' field of the stream context during 'Set TR Dequeue' command. This stream context area is where xHC stores information about the last partially executed TD when a stream is stopped. xHC uses this information to resume the transfer where it left mid TD, when the stream is restarted.

[PATCH v3] PCI: pci_call_probe: call local_pci_probe() when selected cpu is offline

by Hongchen Zhang

Call work_on_cpu(cpu, fn, arg) in pci_call_probe() while the argument @cpu is a offline cpu would cause system stuck forever. This can be happen if a node is online while all its CPUs are offline (We can use "maxcpus=1" without "nr_cpus=1" to reproduce it). So, in the above case, let pci_call_probe() call local_pci_probe() instead of work_on_cpu() when the best selected cpu is offline.

[PATCH v6 2/2] ufs: core: requeue aborted request

From: Peter Wang <peter.wang(a)mediatek.com> ufshcd_abort_all forcibly aborts all on-going commands and the host controller will automatically fill in the OCS field of the corresponding response with OCS_ABORTED based on different working modes. MCQ mode: aborts a command using SQ cleanup, The host controller will post a Completion Queue entry with OCS = ABORTED. SDB mode: aborts a command using UTRLCLR. Task Management response which means a Transfer Request was aborted. For these two cases, set a flag to notify SCSI to requeue the command after receiving response with OCS_ABORTED.

[PATCH] HID: plantronics: Additional PID for double volume key presses quirk

by Wade Wang

Add the below headsets for double volume key presses quirk Plantronics EncorePro 500 Series (047f:431e) Plantronics Blackwire_3325 Series (047f:430c) Quote from previous patch by Maxim Mikityanskiy and Terry Junge 'commit f567d6ef8606 ("HID: plantronics: Workaround for double volume key presses")' 'commit 3d57f36c89d8 ("HID: plantronics: Additional PIDs for double volume key presses quirk")' These Plantronics Series headset sends an opposite volume key following each volume key press. This patch adds a quirk to hid-plantronics for this product ID, which will ignore the second opposite volume key press if it happens within 250 ms from the last one that was handled.

[PATCH 3/8] lpfc: Restrict support for 32 byte CDBs to specific HBAs

by Justin Tee

An older generation of HBAs are failing FCP discovery due to usage of an outdated field in FCP command WQEs. Fix by checking the SLI Interface Type register for applicable support of 32 Byte CDB commands, and restore a setting for a WQE path using normal 16 byte CDBs.

[PATCH v2] clocksource: hyper-v: Fix hv tsc page based sched_clock for hibernation

by Naman Jain

read_hv_sched_clock_tsc() assumes that the Hyper-V clock counter is bigger than the variable hv_sched_clock_offset, which is cached during early boot, but depending on the timing this assumption may be false when a hibernated VM starts again (the clock counter starts from 0 again) and is resuming back (Note: hv_init_tsc_clocksource() is not called during hibernation/resume); consequently, read_hv_sched_clock_tsc() may return a negative integer (which is interpreted as a huge positive integer since the return type is u64) and new kernel messages are prefixed with huge timestamps before read_hv_sched_clock_tsc() grows big enough (which typically takes several seconds). Fix the issue by saving the Hyper-V clock counter just before the suspend, and using it to correct the hv_sched_clock_offset in resume. Override x86_platform.save_sched_clock_state and x86_platform.restore_sched_clock_state. Note: if Invariant TSC is available, the issue doesn't happen because 1) we don't register read_hv_sched_clock_tsc() for sched clock: See commit e5313f1c5404 ("clocksource/drivers/hyper-v: Rework clocksource and sched clock setup"); 2) the common x86 code adjusts TSC similarly: see __restore_processor_state() -> tsc_verify_tsc_adjust(true) and x86_platform.restore_sched_clock_state().

[PATCH net v2] net: tighten bad gso csum offset check in virtio_net_hdr

by Willem de Bruijn

From: Willem de Bruijn <willemb(a)google.com> The referenced commit drops bad input, but has false positives. Tighten the check to avoid these. The check detects illegal checksum offload requests, which produce csum_start/csum_off beyond end of packet after segmentation. But it is based on two incorrect assumptions: 1. virtio_net_hdr_to_skb with VIRTIO_NET_HDR_GSO_TCP[46] implies GSO. True in callers that inject into the tx path, such as tap. But false in callers that inject into rx, like virtio-net. Here, the flags indicate GRO, and CHECKSUM_UNNECESSARY or CHECKSUM_NONE without VIRTIO_NET_HDR_F_NEEDS_CSUM is normal. 2. TSO requires checksum offload, i.e., ip_summed == CHECKSUM_PARTIAL. False, as tcp[46]_gso_segment will fix up csum_start and offset for all other ip_summed by calling __tcp_v4_send_check. Because of 2, we can limit the scope of the fix to virtio_net_hdr that do try to set these fields, with a bogus value.

Move the code "worker->pool = NULL;" out from detach_worker() to fix the problem. worker->pool had been designed to be constant for regular workers and changeable for rescuer. To share attaching/detaching code for regular and rescuer workers and to avoid worker->pool being accessed inadvertently when the worker has been detached, worker->pool is reset to NULL when detached no matter the worker is rescuer or not. To maintain worker->pool being reset after detached, move the code "worker->pool = NULL;" in the worker thread context after detached. It is either be in the regular worker thread context after PF_WQ_WORKER is cleared or in rescuer worker thread context with wq_pool_attach_mutex held. So it is safe to do so.

[PATCH] brbd: Fix atomicity violation in drbd_uuid_set_bm()

by Qiu-ji Chen

The violation of atomicity occurs when the brbd_uuid_set_bm function is executed simultaneously with modifying the value of device->ldev->md.uuid[UI_BITMAP]. Consider a scenario where, while device->ldev->md.uuid[UI_BITMAP] passes the validity check when its value is not zero, the value of device->ldev->md.uuid[UI_BITMAP] is written to zero. In this case, the check in brbd_uuid_set_bm might refer to the old value of device->ldev->md.uuid[UI_BITMAP] (before locking), which allows an invalid value to pass the validity check, resulting in inconsistency. To address this issue, it is recommended to include the data validity check within the locked section of the function. This modification ensures that the value of device->ldev->md.uuid[UI_BITMAP] does not change during the validation process, thereby maintaining its integrity. This possible bug is found by an experimental static analysis tool developed by our team. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations.

[PATCH 1/1] x86: SMP broken on Xen PV DomU since 6.9

by Niels Dettenbach

Virtual machines under Xen Hypervisor (DomU) running in Xen PV mode use a special, nonstandard synthetized CPU topology which "just works" under kernels 6.9.x while newer kernels wrongly assuming a "crash kernel" and disable SMP (reducing to one CPU core) because the newer topology implementation produces a wrong error "[Firmware Bug]: APIC enumeration order not specification compliant" after new topology checks which are improper for Xen PV platform. As a result, the kernel disables SMT and activates just one CPU core within the VM (DomU). The patch disables the regarding checks if it is running in Xen PV mode (only) and bring back SMP / all CPUs as in the past to such DomU VMs. Signed-off-by: Niels Dettenbach <nd(a)syndicat.com> --- The current behaviour leads all of our production Xen Host platforms (amd64 - HPE proliant) unusable after updating to newer linux kernels (with just one CPU available/activated per VM) while older kernels and other OS (current NetBSD PV DomU) still work fully (and stable since many years on the platform). Xen PV mode is still provided by current Xen and widely used - even if less wide as the newer Xen PVH mode today. So a solution probably will be required. So we assume that bug affects stable(a)vger.kernel.org as well. dmesg from affected kernel: -- snip -- [ 0.640364] CPU topo: Enumerated BSP APIC 0 is not marked in APICBASE MSR [ 0.640367] CPU topo: Assuming crash kernel.

[PATCH net 2/5] can: esd_usb: Remove CAN_CTRLMODE_3_SAMPLES for CAN-USB/3-FD

by Marc Kleine-Budde

From: Stefan Mätje <stefan.maetje(a)esd.eu> Remove the CAN_CTRLMODE_3_SAMPLES announcement for CAN-USB/3-FD devices because these devices don't support it. The hardware has a Microchip SAM E70 microcontroller that uses a Bosch MCAN IP core as CAN FD controller. But this MCAN core doesn't support triple sampling.

[PATCH rc] iommu/amd: Fix argument order in amd_iommu_dev_flush_pasid_all()

by Jason Gunthorpe

From: Eliav Bar-ilan <eliavb(a)nvidia.com> An incorrect argument order calling amd_iommu_dev_flush_pasid_pages() causes improper flushing of the IOMMU, leaving the old value of GCR3 from a previous process attached to the same PASID. The function has the signature: void amd_iommu_dev_flush_pasid_pages(struct iommu_dev_data *dev_data, ioasid_t pasid, u64 address, size_t size) Correct the argument order.

[PATCH RFC V3 1/1] ocfs2: reserve space for inline xattr before attaching reflink tree

by Gautham Ananthakrishna

One of our customers reported a crash and a corrupted ocfs2 filesystem. The crash was due to the detection of corruption.

The issue was in the reflink workfow while reserving space for inline xattr. The problematic function is ocfs2_reflink_xattr_inline(). By the time this function is called the reflink tree is already recreated at the destination inode from the source inode. At this point, this function reserves space space inline xattrs at the destination inode without even checking if there is space at the root metadata block. It simply reduces the l_count from 243 to 227 thereby making space of 256 bytes for inline xattr whereas the inode already has extents beyond this index (in this case upto 230), thereby causing corruption. The fix for this is to reserve space for inline metadata before the at the destination inode before the reflink tree gets recreated. The customer has verified the fix.

[PATCH v2 2/3] block: fix ordering between checking QUEUE_FLAG_QUIESCED and adding requests

by Muchun Song

Supposing the following scenario. CPU0 CPU1 blk_mq_insert_request() 1) store blk_mq_unquiesce_queue() blk_mq_run_hw_queue() blk_queue_flag_clear(QUEUE_FLAG_QUIESCED) 3) store if (blk_queue_quiesced()) 2) load blk_mq_run_hw_queues() return blk_mq_run_hw_queue() blk_mq_sched_dispatch_requests() if (!blk_mq_hctx_has_pending()) 4) load return The full memory barrier should be inserted between 1) and 2), as well as between 3) and 4) to make sure that either CPU0 sees QUEUE_FLAG_QUIESCED is cleared or CPU1 sees dispatch list or setting of bitmap of software queue. Otherwise, either CPU will not re-run the hardware queue causing starvation. So the first solution is to 1) add a pair of memory barrier to fix the problem, another solution is to 2) use hctx->queue->queue_lock to synchronize QUEUE_FLAG_QUIESCED. Here, we chose 2) to fix it since memory barrier is not easy to be maintained.

[PATCH 1/1] x86: SMT broken on Xen PV DomU since 6.9

by Niels Dettenbach

virtual machines under Xen Hypervisor (DomU) running in Xen PV mode use a special, nonstandard synthetized CPU topology which "just works" under kernels 6.9.x while newer kernels assuming a "crash kernel" and disable SMT (reducing to one CPU core) because the newer topology implementation produces a wrong error "[Firmware Bug]: APIC enumeration order not specification compliant" after new topology checks which are improper for Xen PV platform. As a result, the kernel disables SMT and activates just one CPU core within the VM (DomU). The patch disables the regarding checks if it is running in Xen PV mode (only) and bring back SMT / all CPUs as in the past to such DomU VMs. Signed-off-by: Niels Dettenbach <nd(a)syndicat.com> --- The current behaviour leads all of our production Xen Host platforms unusable after updating to newer linux kernels (with just one CPU available/activated per VM) while older kernels other OS still work fully (and stable since many years on the platform). Xen PV mode is still provided by current Xen and widely used - even if less wide as the newer Xen PVH mode today. So a solution probably will be required.

[PATCH] usb: dwc3: Runtime get and put usb power_supply handle

by Kyle Tso

It is possible that the usb power_supply is registered after the probe of dwc3. In this case, trying to get the usb power_supply during the probe will fail and there is no chance to try again.

[PATCH v2 1/8] serial: qcom-geni: fix fifo polling timeout

by Johan Hovold

The qcom_geni_serial_poll_bit() can be used to wait for events like command completion and is supposed to wait for the time it takes to clear a full fifo before timing out. As noted by Doug, the current implementation does not account for start, stop and parity bits when determining the timeout. The helper also does not currently account for the shift register and the two-word intermediate transfer register. A too short timeout can specifically lead to lost characters when waiting for a transfer to complete as the transfer is cancelled on timeout. Instead of determining the poll timeout on every call, store the fifo timeout when updating it in set_termios() and make sure to take the shift and intermediate registers into account. Note that serial core has already added a 20 ms margin to the fifo timeout. Also note that the current uart_fifo_timeout() interface does unnecessary calculations on every call and did not exist in earlier kernels so only store its result once. This facilitates backports too as earlier kernels can derive the timeout from uport->timeout, which has since been removed.

[PATCH hotfix 6.11] minmax: reduce egregious min/max macro expansion

by Lorenzo Stoakes

Avoid nested min()/max() which results in egregious macro expansion. This issue was introduced by commit 867046cc7027 ("minmax: relax check to allow comparison between unsigned arguments and signed constants") [2]. Work has been done to address the issue of egregious min()/max() macro expansion in commit 22f546873149 ("minmax: improve macro expansion and type checking") and related, however it appears that some issues remain on more tightly constrained systems. Adjust a few known-bad cases of deeply nested macros to avoid doing so to mitigate this. Porting the patch first proposed in [1] to Linus's tree. Running an allmodconfig build using the methodology described in [2] we observe a 35 MiB reduction in generated code. The difference is much more significant prior to recent minmax fixes which were not backported. As per [1] prior these the reduction is more like 200 MiB. This resolves an issue with slackware 15.0 32-bit compilation as reported by Richard Narron. Presumably the min/max fixups would be difficult to backport, this patch should be easier and fix's Richard's problem in 5.15.

This patch addresses a reference count handling issue in the ice_dpll_init_rclk_pins() function. The function calls ice_dpll_get_pins(), which increments the reference count of the relevant resources. However, if the condition WARN_ON((!vsi || !vsi->netdev)) is met, the function currently returns an error without properly releasing the resources acquired by ice_dpll_get_pins(), leading to a reference count leak. To resolve this, the check has been moved to the top of the function. This ensures that the function verifies the state before any resources are acquired, avoiding the need for additional resource management in the error path. This bug was identified by an experimental static analysis tool developed by our team. The tool specializes in analyzing reference count operations and detecting potential issues where resources are not properly managed. In this case, the tool flagged the missing release operation as a potential problem, which led to the development of this patch.

[PATCH v3] i2c: aspeed: Update the stop sw state when the bus recovery occurs

by Tommy Huang

When the i2c bus recovery occurs, driver will send i2c stop command in the scl low condition. In this case the sw state will still keep original situation. Under multi-master usage, i2c bus recovery will be called when i2c transfer timeout occurs. Update the stop command calling with aspeed_i2c_do_stop function to update master_state.

[PATCH v2 1/4] drm/xe/client: fix deadlock in show_meminfo()

by Matthew Auld

There is a real deadlock as well as sleeping in atomic() bug in here, if the bo put happens to be the last ref, since bo destruction wants to grab the same spinlock and sleeping locks. Fix that by dropping the ref using xe_bo_put_deferred(), and moving the final commit outside of the lock. Dropping the lock around the put is tricky since the bo can go out of scope and delete itself from the list, making it difficult to navigate to the next list entry.

[PATCH v6 1/6] x86/tdx: Fix "in-kernel MMIO" check

by Alexey Gladkov

From: "Alexey Gladkov (Intel)" <legion(a)kernel.org> TDX only supports kernel-initiated MMIO operations. The handle_mmio() function checks if the #VE exception occurred in the kernel and rejects the operation if it did not. However, userspace can deceive the kernel into performing MMIO on its behalf. For example, if userspace can point a syscall to an MMIO address, syscall does get_user() or put_user() on it, triggering MMIO #VE. The kernel will treat the #VE as in-kernel MMIO. Ensure that the target MMIO address is within the kernel before decoding instruction.

[PATCH 3/4] phy: qcom: qmp-usbc: fix NULL-deref on runtime suspend

by Johan Hovold

Commit 413db06c05e7 ("phy: qcom-qmp-usb: clean up probe initialisation") removed most users of the platform device driver data from the qcom-qmp-usb driver, but mistakenly also removed the initialisation despite the data still being used in the runtime PM callbacks. This bug was later reproduced when the driver was copied to create the qmp-usbc driver. Restore the driver data initialisation at probe to avoid a NULL-pointer dereference on runtime suspend. Apparently no one uses runtime PM, which currently needs to be enabled manually through sysfs, with these drivers.

[PATCH] perf/x86/intel: Allow to setup LBR for counting event for BPF

by kan.liang＠linux.intel.com

From: Kan Liang <kan.liang(a)linux.intel.com> The BPF subsystem may capture LBR data on a counting event. However, the current implementation assumes that LBR can/should only be used with sampling events. For instance, retsnoop tool ([0]) makes an extensive use of this functionality and sets up perf event as follows: struct perf_event_attr attr; memset(&attr, 0, sizeof(attr)); attr.size = sizeof(attr); attr.type = PERF_TYPE_HARDWARE; attr.config = PERF_COUNT_HW_CPU_CYCLES; attr.sample_type = PERF_SAMPLE_BRANCH_STACK; attr.branch_sample_type = PERF_SAMPLE_BRANCH_KERNEL; To limit the LBR for a sampling event is to avoid unnecessary branch stack setup for a counting event in the sample read. Because LBR is only read in the sampling event's overflow. Although in most cases LBR is used in sampling, there is no HW limit to bind LBR to the sampling mode. Allow an LBR setup for a counting event unless in the sample read mode.

[PATCH 1/4] drm/xe/client: fix deadlock in show_meminfo()

by Matthew Auld

There is a real deadlock as well as sleeping in atomic() bug in here, if the bo put happens to be the last ref, since bo destruction wants to grab the same spinlock and sleeping locks. Fix that by dropping the ref using xe_bo_put_deferred(), and moving the final commit outside of the lock. Dropping the lock around the put is tricky since the bo can go out of scope and delete itself from the list, making it difficult to navigate to the next list entry.

[PATCH RESEND] soundwire: stream: Revert "soundwire: stream: fix programming slave ports for non-continous port maps"

by Krzysztof Kozlowski

This reverts commit ab8d66d132bc8f1992d3eb6cab8d32dda6733c84 because it breaks codecs using non-continuous masks in source and sink ports. The commit missed the point that port numbers are not used as indices for iterating over prop.sink_ports or prop.source_ports. Soundwire core and existing codecs expect that the array passed as prop.sink_ports and prop.source_ports is continuous. The port mask still might be non-continuous, but that's unrelated.

Follow-up to "net: drop bad gso csum_start and offset in virtio_net_hdr" - backport for 5.15 needed

by Christian Theune

Hi, the issue was so far handled in https://lore.kernel.org/regressions/ZsyMzW-4ee_U8NoX@eldamar.lan/T/#m390d6e… and https://bugzilla.kernel.org/show_bug.cgi?id=219129 I haven’t seen any communication whether a backport for 5.15 is already in progress, so I thought I’d follow up here. Today we rolled out 5.15.165 and immediately ran into the same issue. There’s at least one other person asking for a 5.15 backport in Bugzilla.

[PATCH] fbdev/xen-fbfront: Assign fb_info->device

by Jason Andryuk

From: Jason Andryuk <jason.andryuk(a)amd.com> Probing xen-fbfront faults in video_is_primary_device(). The passed-in struct device is NULL since xen-fbfront doesn't assign it and the memory is kzalloc()-ed. Assign fb_info->device to avoid this. This was exposed by the conversion of fb_is_primary_device() to video_is_primary_device() which dropped a NULL check for struct device.

[PATCH net] net: tighten bad gso csum offset check in virtio_net_hdr

by Willem de Bruijn

From: Willem de Bruijn <willemb(a)google.com> The referenced commit drops bad input, but has false positives. Tighten the check to avoid these. The check detects illegal checksum offload requests, which produce csum_start/csum_off beyond end of packet after segmentation. But it is based on two incorrect assumptions: 1. virtio_net_hdr_to_skb with VIRTIO_NET_HDR_GSO_TCP[46] implies GSO. True in callers that inject into the tx path, such as tap. But false in callers that inject into rx, like virtio-net. Here, the flags indicate GRO, and CHECKSUM_UNNECESSARY or CHECKSUM_NONE without VIRTIO_NET_HDR_F_NEEDS_CSUM is normal. 2. TSO requires checksum offload, i.e., ip_summed == CHECKSUM_PARTIAL. False, as tcp[46]_gso_segment will fix up csum_start and offset for all other ip_summed by calling __tcp_v4_send_check. Because of 2, we can limit the scope of the fix to virtio_net_hdr that do try to set these fields, with a bogus value. Link: https://lore.kernel.org/netdev/20240909094527.GA3048202@port70.net/ Fixes: 89add40066f9 ("net: drop bad gso csum_start and offset in virtio_net_hdr") Signed-off-by: Willem de Bruijn <willemb(a)google.com> Cc: <stable(a)vger.kernel.net> --- Verified that the syzbot repro is still caught. An equivalent alternative would be to move the check for csum_offset to where the csum_start check is in segmentation: - if (unlikely(skb_checksum_start(skb) != skb_transport_header(skb))) + if (unlikely(skb_checksum_start(skb) != skb_transport_header(skb) || + skb->csum_offset != offsetof(struct tcphdr, check))) Cleaner, but messier stable backport. We'll need an equivalent patch to this for VIRTIO_NET_HDR_GSO_UDP_L4. But that csum_offset test was in a different commit, so different Fixes tag. --- include/linux/virtio_net.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/include/linux/virtio_net.h b/include/linux/virtio_net.h index 6c395a2600e8d..276ca543ef44d 100644 --- a/include/linux/virtio_net.h +++ b/include/linux/virtio_net.h @@ -173,7 +173,8 @@ static inline int virtio_net_hdr_to_skb(struct sk_buff *skb, break; case SKB_GSO_TCPV4: case SKB_GSO_TCPV6: - if (skb->csum_offset != offsetof(struct tcphdr, check)) + if (skb->ip_summed == CHECKSUM_PARTIAL && + skb->csum_offset != offsetof(struct tcphdr, check)) return -EINVAL; break; } -- 2.46.0.598.g6f2099f65c-goog

[PATCH v2 3/3] block: fix ordering between checking BLK_MQ_S_STOPPED and adding requests

by Muchun Song

Supposing first scenario with a virtio_blk driver. CPU0 CPU1 blk_mq_try_issue_directly() __blk_mq_issue_directly() q->mq_ops->queue_rq() virtio_queue_rq() blk_mq_stop_hw_queue() virtblk_done() blk_mq_request_bypass_insert() blk_mq_start_stopped_hw_queues() /* Add IO request to dispatch list */ 1) store blk_mq_start_stopped_hw_queue() clear_bit(BLK_MQ_S_STOPPED) 3) store blk_mq_run_hw_queue() blk_mq_run_hw_queue() if (!blk_mq_hctx_has_pending()) if (!blk_mq_hctx_has_pending()) 4) load return return blk_mq_sched_dispatch_requests() blk_mq_sched_dispatch_requests() if (blk_mq_hctx_stopped()) 2) load if (blk_mq_hctx_stopped()) return return __blk_mq_sched_dispatch_requests() __blk_mq_sched_dispatch_requests() Supposing another scenario. CPU0 CPU1 blk_mq_requeue_work() /* Add IO request to dispatch list */ 1) store virtblk_done() blk_mq_run_hw_queues()/blk_mq_delay_run_hw_queues() blk_mq_start_stopped_hw_queues() if (blk_mq_hctx_stopped()) 2) load blk_mq_start_stopped_hw_queue() continue clear_bit(BLK_MQ_S_STOPPED) 3) store blk_mq_run_hw_queue()/blk_mq_delay_run_hw_queue() blk_mq_run_hw_queue() if (!blk_mq_hctx_has_pending()) 4) load return blk_mq_sched_dispatch_requests() Both scenarios are similar, the full memory barrier should be inserted between 1) and 2), as well as between 3) and 4) to make sure that either CPU0 sees BLK_MQ_S_STOPPED is cleared or CPU1 sees dispatch list. Otherwise, either CPU will not rerun the hardware queue causing starvation of the request. The easy way to fix it is to add the essential full memory barrier into helper of blk_mq_hctx_stopped(). In order to not affect the fast path (hardware queue is not stopped most of the time), we only insert the barrier into the slow path. Actually, only slow path needs to care about missing of dispatching the request to the low-level device driver.

[PATCH v2 1/3] block: fix missing dispatching request when queue is started or unquiesced

by Muchun Song

Supposing the following scenario with a virtio_blk driver. CPU0 CPU1 CPU2 blk_mq_try_issue_directly() __blk_mq_issue_directly() q->mq_ops->queue_rq() virtio_queue_rq() blk_mq_stop_hw_queue() blk_mq_try_issue_directly() virtblk_done() if (blk_mq_hctx_stopped()) blk_mq_request_bypass_insert() blk_mq_start_stopped_hw_queue() blk_mq_run_hw_queue() blk_mq_run_hw_queue() blk_mq_insert_request() return // Who is responsible for dispatching this IO request? After CPU0 has marked the queue as stopped, CPU1 will see the queue is stopped. But before CPU1 puts the request on the dispatch list, CPU2 receives the interrupt of completion of request, so it will run the hardware queue and marks the queue as non-stopped. Meanwhile, CPU1 also runs the same hardware queue. After both CPU1 and CPU2 complete blk_mq_run_hw_queue(), CPU1 just puts the request to the same hardware queue and returns. It misses dispatching a request. Fix it by running the hardware queue explicitly. And blk_mq_request_issue_directly() should handle a similar situation. Fix it as well.

[PATCH v3] KVM: arm64: Add memory length checks and remove inline in do_ffa_mem_xfer

by Snehal Koukuntla

When we share memory through FF-A and the description of the buffers exceeds the size of the mapped buffer, the fragmentation API is used. The fragmentation API allows specifying chunks of descriptors in subsequent FF-A fragment calls and no upper limit has been established for this. The entire memory region transferred is identified by a handle which can be used to reclaim the transferred memory. To be able to reclaim the memory, the description of the buffers has to fit in the ffa_desc_buf. Add a bounds check on the FF-A sharing path to prevent the memory reclaim from failing. Also do_ffa_mem_xfer() does not need __always_inline Fixes: 634d90cf0ac65 ("KVM: arm64: Handle FFA_MEM_LEND calls from the host") Cc: stable(a)vger.kernel.org Reviewed-by: Sebastian Ene <sebastianene(a)google.com> Signed-off-by: Snehal Koukuntla <snehalreddy(a)google.com> --- arch/arm64/kvm/hyp/nvhe/ffa.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/arch/arm64/kvm/hyp/nvhe/ffa.c b/arch/arm64/kvm/hyp/nvhe/ffa.c index e715c157c2c4..637425f63fd1 100644 --- a/arch/arm64/kvm/hyp/nvhe/ffa.c +++ b/arch/arm64/kvm/hyp/nvhe/ffa.c @@ -426,7 +426,7 @@ static void do_ffa_mem_frag_tx(struct arm_smccc_res *res, return; } -static __always_inline void do_ffa_mem_xfer(const u64 func_id, +static void do_ffa_mem_xfer(const u64 func_id, struct arm_smccc_res *res, struct kvm_cpu_context *ctxt) { @@ -461,6 +461,11 @@ static __always_inline void do_ffa_mem_xfer(const u64 func_id, goto out_unlock; } + if (len > ffa_desc_buf.len) { + ret = FFA_RET_NO_MEMORY; + goto out_unlock; + } + buf = hyp_buffers.tx; memcpy(buf, host_buffers.tx, fraglen); -- 2.46.0.598.g6f2099f65c-goog

[PATCH 6.6] membarrier: riscv: Add full memory barrier in switch_mm()

by WangYuli

From: Andrea Parri <parri.andrea(a)gmail.com> [ Upstream commit d6cfd1770f20392d7009ae1fdb04733794514fa9 ] The membarrier system call requires a full memory barrier after storing to rq->curr, before going back to user-space. The barrier is only needed when switching between processes: the barrier is implied by mmdrop() when switching from kernel to userspace, and it's not needed when switching from userspace to kernel. Rely on the feature/mechanism ARCH_HAS_MEMBARRIER_CALLBACKS and on the primitive membarrier_arch_switch_mm(), already adopted by the PowerPC architecture, to insert the required barrier.

[PATCH AUTOSEL 6.10 18/18] ice: check for XDP rings instead of bpf program when unconfiguring

by Sasha Levin

From: Larysa Zaremba <larysa.zaremba(a)intel.com> [ Upstream commit f50c68763436bc8f805712a7c5ceaf58cfcf5f07 ] If VSI rebuild is pending, .ndo_bpf() can attach/detach the XDP program on VSI without applying new ring configuration. When unconfiguring the VSI, we can encounter the state in which there is an XDP program but no XDP rings to destroy or there will be XDP rings that need to be destroyed, but no XDP program to indicate their presence. When unconfiguring, rely on the presence of XDP rings rather then XDP program, as they better represent the current state that has to be destroyed.

[PATCH AUTOSEL 6.10 13/18] drm: komeda: Fix an issue related to normalized zpos

by Sasha Levin

From: "hongchi.peng" <hongchi.peng(a)siengine.com> [ Upstream commit 258905cb9a6414be5c9ca4aa20ef855f8dc894d4 ] We use komeda_crtc_normalize_zpos to normalize zpos of affected planes to their blending zorder in CU. If there's only one slave plane in affected planes and its layer_split property is enabled, order++ for its split layer, so that when calculating the normalized_zpos of master planes, the split layer of the slave plane is included, but the max_slave_zorder does not include the split layer and keep zero because there's only one slave plane in affacted planes, although we actually use two slave layers in this commit. In most cases, this bug does not result in a commit failure, but assume the following situation: slave_layer 0: zpos = 0, layer split enabled, normalized_zpos = 0;(use slave_layer 2 as its split layer) master_layer 0: zpos = 2, layer_split enabled, normalized_zpos = 2;(use master_layer 2 as its split layer) master_layer 1: zpos = 4, normalized_zpos = 4; master_layer 3: zpos = 5, normalized_zpos = 5; kcrtc_st->max_slave_zorder = 0; When we use master_layer 3 as a input of CU in function komeda_compiz_set_input and check it with function komeda_component_check_input, the parameter idx is equal to normailzed_zpos minus max_slave_zorder, the value of idx is 5 and is euqal to CU's max_active_inputs, so that komeda_component_check_input returns a -EINVAL value. To fix the bug described above, when calculating the max_slave_zorder with the layer_split enabled, count the split layer in this calculation directly.

[PATCH AUTOSEL 6.10 11/18] clk: qcom: gcc-sm8650: Don't use shared clk_ops for QUPs

by Sasha Levin

From: Neil Armstrong <neil.armstrong(a)linaro.org> [ Upstream commit aa2eb2c4356affa2799efd95a4ee2d239ca630f8 ] The QUPs aren't shared in a way that requires parking the RCG at an always on parent in case some other entity turns on the clk. The hardware is capable of setting a new frequency itself with the DFS mode, so parking is unnecessary. Furthermore, there aren't any GDSCs for these devices, so there isn't a possibility of the GDSC turning on the clks for housekeeping purposes. Like for the SM8550 GCC QUP clocks at [1], do not use shared clk_ops for QUPs.

[PATCH v2 1/3] platform/x86: panasonic-laptop: Fix SINF array out of bounds accesses

by Hans de Goede

The panasonic laptop code in various places uses the SINF array with index values of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF array is big enough. Not all panasonic laptops have this many SINF array entries, for example the Toughbook CF-18 model only has 10 SINF array entries. So it only supports the AC+DC brightness entries and mute. Check that the SINF array has a minimum size which covers all AC+DC brightness entries and refuse to load if the SINF array is smaller. For higher SINF indexes hide the sysfs attributes when the SINF array does not contain an entry for that attribute, avoiding show()/store() accessing the array out of bounds and add bounds checking to the probe() and resume() code accessing these.

However, the usage of `THIS_MODULE` includes passing this pointer to functions that may write to it (probably in unsafe code), and this will create soundness issues. One way to fix this is using `addr_of_mut!()` but that requires the unstable feature "const_mut_refs". So instead of `addr_of_mut()!`, an extern static `Opaque` is used here: since `Opaque<T>` is transparent to `T`, an extern static `Opaque` will just wrap the C symbol (defined in a C compile unit) in an `Opaque`, which provides a pointer with writable provenance via `Opaque::get()`. This fix the potential UBs because of pointer provenance unmatched.

So apply that to LoongArch which is such an architecture, in order to avoid potential problems. Similar to commit edf955647269422e ("riscv: Use accessors to page table entries instead of direct dereference").

[PATCH v2] drm/nouveau/fb: restore init() for ramgp102

by Ben Skeggs

init() was removed from ramgp102 when reworking the memory detection, as it was thought that the code was only necessary when the driver performs mclk changes, which nouveau doesn't support on pascal. However, it turns out that we still need to execute this on some GPUs to restore settings after DEVINIT, so revert to the original behaviour. v2: fix tags in commit message, cc stable Closes: https://gitlab.freedesktop.org/drm/nouveau/-/issues/319 Fixes: 2c0c15a22fa0 ("drm/nouveau/fb/gp102-ga100: switch to simpler vram size detection method") Cc: <stable(a)vger.kernel.org> # 6.6+ Signed-off-by: Ben Skeggs <bskeggs(a)nvidia.com> --- drivers/gpu/drm/nouveau/nvkm/subdev/fb/ram.h | 2 ++ drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgp100.c | 2 +- drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgp102.c | 1 + 3 files changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ram.h b/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ram.h index 50f0c1914f58..4c3f74396579 100644 --- a/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ram.h +++ b/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ram.h @@ -46,6 +46,8 @@ u32 gm107_ram_probe_fbp(const struct nvkm_ram_func *, u32 gm200_ram_probe_fbp_amount(const struct nvkm_ram_func *, u32, struct nvkm_device *, int, int *); +int gp100_ram_init(struct nvkm_ram *); + /* RAM type-specific MR calculation routines */ int nvkm_sddr2_calc(struct nvkm_ram *); int nvkm_sddr3_calc(struct nvkm_ram *); diff --git a/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgp100.c b/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgp100.c index 378f6fb70990..8987a21e81d1 100644 --- a/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgp100.c +++ b/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgp100.c @@ -27,7 +27,7 @@ #include <subdev/bios/init.h> #include <subdev/bios/rammap.h> -static int +int gp100_ram_init(struct nvkm_ram *ram) { struct nvkm_subdev *subdev = &ram->fb->subdev; diff --git a/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgp102.c b/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgp102.c index 8550f5e47347..b6b6ee59019d 100644 --- a/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgp102.c +++ b/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgp102.c @@ -5,6 +5,7 @@ static const struct nvkm_ram_func gp102_ram = { + .init = gp100_ram_init, }; int -- 2.45.1

So apply that to LoongArch which is such an architecture, in order to avoid potential problems.

[PATCH] pcmcia: Fix a NULL pointer dereference in __iodyn_find_io_region()

by Ma Ke

In __iodyn_find_io_region(), pcmcia_make_resource() is assigned to res and used in pci_bus_alloc_resource(). There is a dereference of res in pci_bus_alloc_resource(), which could lead to a NULL pointer dereference on failure of pcmcia_make_resource(). Fix this bug by adding a check of res. Found by code review, complie tested only.

[PATCH] Revert "f2fs: stop allocating pinned sections if EAGAIN happens"

by Wu Bo

This reverts commit 2e42b7f817acd6e8d78226445eb6fe44fe79c12a. If the GC victim section has a pinned block when fallocate() trigger FG_GC, the section is not able to be recycled. And this will return -EAGAIN cause fallocate() failed, even though there are much spare space as user see. As the GC policy prone to chose the same victim, fallocate() may not successed at a long period. This scenario has been found during Android OTA.

[PATCH 4.19] net, sunrpc: Remap EPERM in case of connection failure in xs_tcp_setup_socket

by hsimeliere.opensource＠witekio.com

From: Daniel Borkmann <daniel(a)iogearbox.net> commit 626dfed5fa3bfb41e0dffd796032b555b69f9cde upstream. When using a BPF program on kernel_connect(), the call can return -EPERM. This causes xs_tcp_setup_socket() to loop forever, filling up the syslog and causing the kernel to potentially freeze up. Neil suggested: This will propagate -EPERM up into other layers which might not be ready to handle it. It might be safer to map EPERM to an error we would be more likely to expect from the network system - such as ECONNREFUSED or ENETDOWN. ECONNREFUSED as error seems reasonable. For programs setting a different error can be out of reach (see handling in 4fbac77d2d09) in particular on kernels which do not have f10d05966196 ("bpf: Make BPF_PROG_RUN_ARRAY return -err instead of allow boolean"), thus given that it is better to simply remap for consistent behavior. UDP does handle EPERM in xs_udp_send_request().

It introduced IDR to maintain the memcg ID space. The IDR depends on external synchronization mechanisms for modifications. For the mem_cgroup_idr, the idr_alloc() and idr_replace() happen within css callback and thus are protected through cgroup_mutex from concurrent modifications. However idr_remove() for mem_cgroup_idr was not protected against concurrency and can be run concurrently for different memcgs when they hit their refcnt to zero. Fix that. We have been seeing list_lru based kernel crashes at a low frequency in our fleet for a long time. These crashes were in different part of list_lru code including list_lru_add(), list_lru_del() and reparenting code. Upon further inspection, it looked like for a given object (dentry and inode), the super_block's list_lru didn't have list_lru_one for the memcg of that object. The initial suspicions were either the object is not allocated through kmem_cache_alloc_lru() or somehow memcg_list_lru_alloc() failed to allocate list_lru_one() for a memcg but returned success. No evidence were found for these cases. Looking more deeply, we started seeing situations where valid memcg's id is not present in mem_cgroup_idr and in some cases multiple valid memcgs have same id and mem_cgroup_idr is pointing to one of them. So, the most reasonable explanation is that these situations can happen due to race between multiple idr_remove() calls or race between idr_alloc()/idr_replace() and idr_remove(). These races are causing multiple memcgs to acquire the same ID and then offlining of one of them would cleanup list_lrus on the system for all of them. Later access from other memcgs to the list_lru cause crashes due to missing list_lru_one.

[PATCH for 5.15 stable] btrfs: fix race between direct IO write and fsync when using same fd

by fdmanana＠kernel.org

From: Filipe Manana <fdmanana(a)suse.com> commit cd9253c23aedd61eb5ff11f37a36247cd46faf86 upstream. If we have 2 threads that are using the same file descriptor and one of them is doing direct IO writes while the other is doing fsync, we have a race where we can end up either: 1) Attempt a fsync without holding the inode's lock, triggering an assertion failures when assertions are enabled; 2) Do an invalid memory access from the fsync task because the file private points to memory allocated on stack by the direct IO task and it may be used by the fsync task after the stack was destroyed. The race happens like this: 1) A user space program opens a file descriptor with O_DIRECT; 2) The program spawns 2 threads using libpthread for example; 3) One of the threads uses the file descriptor to do direct IO writes, while the other calls fsync using the same file descriptor. 4) Call task A the thread doing direct IO writes and task B the thread doing fsyncs; 5) Task A does a direct IO write, and at btrfs_direct_write() sets the file's private to an on stack allocated private with the member 'fsync_skip_inode_lock' set to true; 6) Task B enters btrfs_sync_file() and sees that there's a private structure associated to the file which has 'fsync_skip_inode_lock' set to true, so it skips locking the inode's vfs lock; 7) Task A completes the direct IO write, and resets the file's private to NULL since it had no prior private and our private was stack allocated. Then it unlocks the inode's vfs lock; 8) Task B enters btrfs_get_ordered_extents_for_logging(), then the assertion that checks the inode's vfs lock is held fails, since task B never locked it and task A has already unlocked it. The stack trace produced is the following: Aug 21 11:46:43 kerberos kernel: assertion failed: inode_is_locked(&inode->vfs_inode), in fs/btrfs/ordered-data.c:983 Aug 21 11:46:43 kerberos kernel: ------------[ cut here ]------------ Aug 21 11:46:43 kerberos kernel: kernel BUG at fs/btrfs/ordered-data.c:983!

This issue, triggering the assertion, was observed with QEMU workloads by two users in the Link tags below. Fix this by not relying on a file's private to pass information to fsync that it should skip locking the inode and instead pass this information through a special value stored in current->journal_info. This is safe because in the relevant section of the direct IO write path we are not holding a transaction handle, so current->journal_info is NULL. The following C program triggers the issue: $ cat repro.c /* Get the O_DIRECT definition. */ #ifndef _GNU_SOURCE #define _GNU_SOURCE #endif #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <stdint.h> #include <fcntl.h> #include <errno.h> #include <string.h> #include <pthread.h> static int fd; static ssize_t do_write(int fd, const void *buf, size_t count, off_t offset) { while (count > 0) { ssize_t ret; ret = pwrite(fd, buf, count, offset); if (ret < 0) { if (errno == EINTR) continue; return ret; } count -= ret; buf += ret; } return 0; } static void *fsync_loop(void *arg) { while (1) { int ret; ret = fsync(fd); if (ret != 0) { perror("Fsync failed"); exit(6); } } } int main(int argc, char *argv[]) { long pagesize; void *write_buf; pthread_t fsyncer; int ret; if (argc != 2) { fprintf(stderr, "Use: %s <file path>\n", argv[0]); return 1; } fd = open(argv[1], O_WRONLY | O_CREAT | O_TRUNC | O_DIRECT, 0666); if (fd == -1) { perror("Failed to open/create file"); return 1; } pagesize = sysconf(_SC_PAGE_SIZE); if (pagesize == -1) { perror("Failed to get page size"); return 2; } ret = posix_memalign(&write_buf, pagesize, pagesize); if (ret) { perror("Failed to allocate buffer"); return 3; } ret = pthread_create(&fsyncer, NULL, fsync_loop, NULL); if (ret != 0) { fprintf(stderr, "Failed to create writer thread: %d\n", ret); return 4; } while (1) { ret = do_write(fd, write_buf, pagesize, 0); if (ret != 0) { perror("Write failed"); exit(5); } } return 0; } $ mkfs.btrfs -f /dev/sdi $ mount /dev/sdi /mnt/sdi $ timeout 10 ./repro /mnt/sdi/foo Usually the race is triggered within less than 1 second.

[PATCH v5.15-v5.4] net, sunrpc: Remap EPERM in case of connection failure in xs_tcp_setup_socket

by hsimeliere.opensource＠witekio.com

From: Daniel Borkmann <daniel(a)iogearbox.net> commit 626dfed5fa3bfb41e0dffd796032b555b69f9cde upstream. When using a BPF program on kernel_connect(), the call can return -EPERM. This causes xs_tcp_setup_socket() to loop forever, filling up the syslog and causing the kernel to potentially freeze up. Neil suggested: This will propagate -EPERM up into other layers which might not be ready to handle it. It might be safer to map EPERM to an error we would be more likely to expect from the network system - such as ECONNREFUSED or ENETDOWN. ECONNREFUSED as error seems reasonable. For programs setting a different error can be out of reach (see handling in 4fbac77d2d09) in particular on kernels which do not have f10d05966196 ("bpf: Make BPF_PROG_RUN_ARRAY return -err instead of allow boolean"), thus given that it is better to simply remap for consistent behavior. UDP does handle EPERM in xs_udp_send_request().

Thanks, tglx --- From: Thomas Gleixner <tglx(a)linutronix.de> Date: Tue Aug 6 20:48:43 2024 +0200 Subject: [PATCH 6.6.y, 6.1.y, 5.10.y] x86/mm: Fix PTI for i386 some more commit c48b5a4cf3125adb679e28ef093f66ff81368d05 upstream. So it turns out that we have to do two passes of pti_clone_entry_text(), once before initcalls, such that device and late initcalls can use user-mode-helper / modprobe and once after free_initmem() / mark_readonly(). Now obviously mark_readonly() can cause PMD splits, and pti_clone_pgtable() doesn't like that much. Allow the late clone to split PMDs so that pagetables stay in sync.

[PATCH] clocksource: hyper-v: Fix hv tsc page based sched_clock for hibernation

by Naman Jain

read_hv_sched_clock_tsc() assumes that the Hyper-V clock counter is bigger than the variable hv_sched_clock_offset, which is cached during early boot, but depending on the timing this assumption may be false when a hibernated VM starts again (the clock counter starts from 0 again) and is resuming back (Note: hv_init_tsc_clocksource() is not called during hibernation/resume); consequently, read_hv_sched_clock_tsc() may return a negative integer (which is interpreted as a huge positive integer since the return type is u64) and new kernel messages are prefixed with huge timestamps before read_hv_sched_clock_tsc() grows big enough (which typically takes several seconds). Fix the issue by saving the Hyper-V clock counter just before the suspend, and using it to correct the hv_sched_clock_offset in resume. Override x86_platform.save_sched_clock_state and x86_platform.restore_sched_clock_state so that we don't have to touch the common x86 code. Note: if Invariant TSC is available, the issue doesn't happen because 1) we don't register read_hv_sched_clock_tsc() for sched clock: See commit e5313f1c5404 ("clocksource/drivers/hyper-v: Rework clocksource and sched clock setup"); 2) the common x86 code adjusts TSC similarly: see __restore_processor_state() -> tsc_verify_tsc_adjust(true) and x86_platform.restore_sched_clock_state().

[PATCH net v2] net: drop bad gso csum_start and offset in virtio_net_hdr

This is already done for USO. Extend it to TSO. Let UFO be: udp[46]_ufo_fragment ignores these fields and always computes the checksum in software. csum_start: finding the real offset requires parsing to the transport header. Do not add a parser, use existing segmentation parsing. Thanks to SKB_GSO_DODGY, that also catches bad packets that are hw offloaded. Again test both TSO and USO. Do not test UFO for the above reason, and do not test UDP tunnel offload. GSO packet are almost always CHECKSUM_PARTIAL. USO packets may be CHECKSUM_NONE since commit 10154dbded6d6 ("udp: Allow GSO transmit from devices with no checksum offload"), but then still these fields are initialized correctly in udp4_hwcsum/udp6_hwcsum_outgoing. So no need to test for ip_summed == CHECKSUM_PARTIAL first. This revises an existing fix mentioned in the Fixes tag, which broke small packets with GSO offload, as detected by kselftests.

[merged mm-stable] mm-codetag-fix-pgalloc_tag_split.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/codetag: fix pgalloc_tag_split() has been removed from the -mm tree. Its filename was mm-codetag-fix-pgalloc_tag_split.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Yu Zhao <yuzhao(a)google.com> Subject: mm/codetag: fix pgalloc_tag_split() Date: Thu, 5 Sep 2024 22:21:07 -0600 The current assumption is that a large folio can only be split into order-0 folios. That is not the case for hugeTLB demotion, nor for THP split: see commit c010d47f107f ("mm: thp: split huge page to any lower order pages"). When a large folio is split into ones of a lower non-zero order, only the new head pages should be tagged. Tagging tail pages can cause imbalanced "calls" counters, since only head pages are untagged by pgalloc_tag_sub() and the "calls" counts on tail pages are leaked, e.g., # echo 2048kB >/sys/kernel/mm/hugepages/hugepages-1048576kB/demote_size # echo 700 >/sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages # time echo 700 >/sys/kernel/mm/hugepages/hugepages-1048576kB/demote # echo 0 >/sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages # grep alloc_gigantic_folio /proc/allocinfo Before this patch: 0 549427200 mm/hugetlb.c:1549 func:alloc_gigantic_folio real 0m2.057s user 0m0.000s sys 0m2.051s After this patch: 0 0 mm/hugetlb.c:1549 func:alloc_gigantic_folio real 0m1.711s user 0m0.000s sys 0m1.704s Not tagging tail pages also improves the splitting time, e.g., by about 15% when demoting 1GB hugeTLB folios to 2MB ones, as shown above.

Date: Mon, 2 Sep 2024 11:08:44 +0800 During the mounting process, if journal_reset() fails because of too short journal, then lead to jbd2_journal_load() fails with NULL j_sb_buffer. Subsequently, ocfs2_journal_shutdown() calls jbd2_journal_flush()->jbd2_cleanup_journal_tail()-> __jbd2_update_log_tail()->jbd2_journal_update_sb_log_tail() ->lock_buffer(journal->j_sb_buffer), resulting in a null-pointer dereference error. To resolve this issue, we should check the JBD2_LOADED flag to ensure the journal was properly loaded. Additionally, use journal instead of osb->journal directly to simplify the code.

[PATCH net-next v3 5/6] idpf: fix netdev Tx queue stop/wake

by Tony Nguyen

From: Michal Kubiak <michal.kubiak(a)intel.com> netif_txq_maybe_stop() returns -1, 0, or 1, while idpf_tx_maybe_stop_common() says it returns 0 or -EBUSY. As a result, there sometimes are Tx queue timeout warnings despite that the queue is empty or there is at least enough space to restart it. Make idpf_tx_maybe_stop_common() inline and returning true or false, handling the return of netif_txq_maybe_stop() properly. Use a correct goto in idpf_tx_maybe_stop_splitq() to avoid stopping the queue or incrementing the stops counter twice.

[PATCH] wifi: mwifiex: Ensure all STA and AP use the same channel

by Sascha Hauer

The mwifiex chips support simultaneous Accesspoint and station mode, but this only works when all are using the same channel. The downstream driver uses ECSA which makes the Accesspoint automatically switch to the channel the station is going to use. Until this is implemented in the mwifiex driver at least catch this situation and bail out with an error. Userspace doesn't have a meaningful way to figure out what went wrong, so print an error message to give the user a clue. Without this patch the driver would timeout on the HostCmd_CMD_802_11_ASSOCIATE command when creating a station with a channel different from the one that an existing accesspoint uses.

[PATCH 00/12] mwifiex: two fixes and cleanup

by Sascha Hauer

These are a few patches broken out from [1]. Kalle requested to limit the number of patches per series to approximately 12 and Francesco to move the fixes to the front of the series, so here we go. First two patches are fixes. First one is for host mlme support which currently is in wireless-next, so no stable tag needed, second one has a stable tag. The remaining patches except the last one I have chosen to upstream first. I'll continue with the other patches after having this series in shape and merged. The last one is a new patch not included in [1].

[PATCH] perf/x86: fix wrong assumption that LBR is only useful for sampling events

by Andrii Nakryiko

It's incorrect to assume that LBR can/should only be used with sampling events. BPF subsystem provides bpf_get_branch_snapshot() BPF helper, which expects a properly setup and activated perf event which allows kernel to capture LBR data. For instance, retsnoop tool ([0]) makes an extensive use of this functionality and sets up perf event as follows: struct perf_event_attr attr; memset(&attr, 0, sizeof(attr)); attr.size = sizeof(attr); attr.type = PERF_TYPE_HARDWARE; attr.config = PERF_COUNT_HW_CPU_CYCLES; attr.sample_type = PERF_SAMPLE_BRANCH_STACK; attr.branch_sample_type = PERF_SAMPLE_BRANCH_KERNEL; Commit referenced in Fixes tag broke this setup by making invalid assumption that LBR is useful only for sampling events. Remove that assumption. Note, earlier we removed a similar assumption on AMD side of LBR support, see [1] for details.

[PATCH] soundwire: stream: fix programming slave ports for non-continous port maps

by Krzysztof Kozlowski

Two bitmasks in 'struct sdw_slave_prop' - 'source_ports' and 'sink_ports' - define which ports to program in sdw_program_slave_port_params(). The masks are used to get the appropriate data port properties ('struct sdw_get_slave_dpn_prop') from an array. Bitmasks can be non-continuous or can start from index different than 0, thus when looking for matching port property for given port, we must iterate over mask bits, not from 0 up to number of ports. This fixes allocation and programming slave ports, when a source or sink masks start from further index.

[PATCH v2] ice: Fix improper handling of refcount in ice_sriov_set_msix_vec_count()

by Gui-Dong Han

This patch addresses an issue with improper reference count handling in the ice_sriov_set_msix_vec_count() function. First, the function calls ice_get_vf_by_id(), which increments the reference count of the vf pointer. If the subsequent call to ice_get_vf_vsi() fails, the function currently returns an error without decrementing the reference count of the vf pointer, leading to a reference count leak. The correct behavior, as implemented in this patch, is to decrement the reference count using ice_put_vf(vf) before returning an error when vsi is NULL. Second, the function calls ice_sriov_get_irqs(), which sets vf->first_vector_idx. If this call returns a negative value, indicating an error, the function returns an error without decrementing the reference count of the vf pointer, resulting in another reference count leak. The patch addresses this by adding a call to ice_put_vf(vf) before returning an error when vf->first_vector_idx < 0. This bug was identified by an experimental static analysis tool developed by our team. The tool specializes in analyzing reference count operations and identifying potential mismanagement of reference counts. In this case, the tool flagged the missing decrement operation as a potential issue, leading to this patch. Fixes: 4035c72dc1ba ("ice: reconfig host after changing MSI-X on VF") Fixes: 4d38cb44bd32 ("ice: manage VFs MSI-X using resource tracking") Cc: stable(a)vger.kernel.org Signed-off-by: Gui-Dong Han <hanguidong02(a)outlook.com> --- v2: * In this patch v2, an additional resource leak was addressed when vf->first_vector_idx < 0.

It introduced IDR to maintain the memcg ID space. The IDR depends on external synchronization mechanisms for modifications. For the mem_cgroup_idr, the idr_alloc() and idr_replace() happen within css callback and thus are protected through cgroup_mutex from concurrent modifications. However idr_remove() for mem_cgroup_idr was not protected against concurrency and can be run concurrently for different memcgs when they hit their refcnt to zero. Fix that. We have been seeing list_lru based kernel crashes at a low frequency in our fleet for a long time. These crashes were in different part of list_lru code including list_lru_add(), list_lru_del() and reparenting code. Upon further inspection, it looked like for a given object (dentry and inode), the super_block's list_lru didn't have list_lru_one for the memcg of that object. The initial suspicions were either the object is not allocated through kmem_cache_alloc_lru() or somehow memcg_list_lru_alloc() failed to allocate list_lru_one() for a memcg but returned success. No evidence were found for these cases. Looking more deeply, we started seeing situations where valid memcg's id is not present in mem_cgroup_idr and in some cases multiple valid memcgs have same id and mem_cgroup_idr is pointing to one of them. So, the most reasonable explanation is that these situations can happen due to race between multiple idr_remove() calls or race between idr_alloc()/idr_replace() and idr_remove().

It introduced IDR to maintain the memcg ID space. The IDR depends on external synchronization mechanisms for modifications. For the mem_cgroup_idr, the idr_alloc() and idr_replace() happen within css callback and thus are protected through cgroup_mutex from concurrent modifications. However idr_remove() for mem_cgroup_idr was not protected against concurrency and can be run concurrently for different memcgs when they hit their refcnt to zero. Fix that. We have been seeing list_lru based kernel crashes at a low frequency in our fleet for a long time. These crashes were in different part of list_lru code including list_lru_add(), list_lru_del() and reparenting code. Upon further inspection, it looked like for a given object (dentry and inode), the super_block's list_lru didn't have list_lru_one for the memcg of that object. The initial suspicions were either the object is not allocated through kmem_cache_alloc_lru() or somehow memcg_list_lru_alloc() failed to allocate list_lru_one() for a memcg but returned success. No evidence were found for these cases. Looking more deeply, we started seeing situations where valid memcg's id is not present in mem_cgroup_idr and in some cases multiple valid memcgs have same id and mem_cgroup_idr is pointing to one of them. So, the most reasonable explanation is that these situations can happen due to race between multiple idr_remove() calls or race between idr_alloc()/idr_replace() and idr_remove(). These races are causing multiple memcgs to acquire the same ID and then offlining of one of them would cleanup list_lrus on the system for all of them. Later access from other memcgs to the list_lru cause crashes due to missing list_lru_one.

[PATCH for 6.1 stable] btrfs: fix race between direct IO write and fsync when using same fd

by fdmanana＠kernel.org

From: Filipe Manana <fdmanana(a)suse.com> commit cd9253c23aedd61eb5ff11f37a36247cd46faf86 upstream. If we have 2 threads that are using the same file descriptor and one of them is doing direct IO writes while the other is doing fsync, we have a race where we can end up either: 1) Attempt a fsync without holding the inode's lock, triggering an assertion failures when assertions are enabled; 2) Do an invalid memory access from the fsync task because the file private points to memory allocated on stack by the direct IO task and it may be used by the fsync task after the stack was destroyed. The race happens like this: 1) A user space program opens a file descriptor with O_DIRECT; 2) The program spawns 2 threads using libpthread for example; 3) One of the threads uses the file descriptor to do direct IO writes, while the other calls fsync using the same file descriptor. 4) Call task A the thread doing direct IO writes and task B the thread doing fsyncs; 5) Task A does a direct IO write, and at btrfs_direct_write() sets the file's private to an on stack allocated private with the member 'fsync_skip_inode_lock' set to true; 6) Task B enters btrfs_sync_file() and sees that there's a private structure associated to the file which has 'fsync_skip_inode_lock' set to true, so it skips locking the inode's vfs lock; 7) Task A completes the direct IO write, and resets the file's private to NULL since it had no prior private and our private was stack allocated. Then it unlocks the inode's vfs lock; 8) Task B enters btrfs_get_ordered_extents_for_logging(), then the assertion that checks the inode's vfs lock is held fails, since task B never locked it and task A has already unlocked it. The stack trace produced is the following: Aug 21 11:46:43 kerberos kernel: assertion failed: inode_is_locked(&inode->vfs_inode), in fs/btrfs/ordered-data.c:983 Aug 21 11:46:43 kerberos kernel: ------------[ cut here ]------------ Aug 21 11:46:43 kerberos kernel: kernel BUG at fs/btrfs/ordered-data.c:983!

This issue, triggering the assertion, was observed with QEMU workloads by two users in the Link tags below. Fix this by not relying on a file's private to pass information to fsync that it should skip locking the inode and instead pass this information through a special value stored in current->journal_info. This is safe because in the relevant section of the direct IO write path we are not holding a transaction handle, so current->journal_info is NULL. The following C program triggers the issue: $ cat repro.c /* Get the O_DIRECT definition. */ #ifndef _GNU_SOURCE #define _GNU_SOURCE #endif #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <stdint.h> #include <fcntl.h> #include <errno.h> #include <string.h> #include <pthread.h> static int fd; static ssize_t do_write(int fd, const void *buf, size_t count, off_t offset) { while (count > 0) { ssize_t ret; ret = pwrite(fd, buf, count, offset); if (ret < 0) { if (errno == EINTR) continue; return ret; } count -= ret; buf += ret; } return 0; } static void *fsync_loop(void *arg) { while (1) { int ret; ret = fsync(fd); if (ret != 0) { perror("Fsync failed"); exit(6); } } } int main(int argc, char *argv[]) { long pagesize; void *write_buf; pthread_t fsyncer; int ret; if (argc != 2) { fprintf(stderr, "Use: %s <file path>\n", argv[0]); return 1; } fd = open(argv[1], O_WRONLY | O_CREAT | O_TRUNC | O_DIRECT, 0666); if (fd == -1) { perror("Failed to open/create file"); return 1; } pagesize = sysconf(_SC_PAGE_SIZE); if (pagesize == -1) { perror("Failed to get page size"); return 2; } ret = posix_memalign(&write_buf, pagesize, pagesize); if (ret) { perror("Failed to allocate buffer"); return 3; } ret = pthread_create(&fsyncer, NULL, fsync_loop, NULL); if (ret != 0) { fprintf(stderr, "Failed to create writer thread: %d\n", ret); return 4; } while (1) { ret = do_write(fd, write_buf, pagesize, 0); if (ret != 0) { perror("Write failed"); exit(5); } } return 0; } $ mkfs.btrfs -f /dev/sdi $ mount /dev/sdi /mnt/sdi $ timeout 10 ./repro /mnt/sdi/foo Usually the race is triggered within less than 1 second.

[PATCH for 6.6 stable] btrfs: fix race between direct IO write and fsync when using same fd

by fdmanana＠kernel.org

From: Filipe Manana <fdmanana(a)suse.com> commit cd9253c23aedd61eb5ff11f37a36247cd46faf86 upstream. If we have 2 threads that are using the same file descriptor and one of them is doing direct IO writes while the other is doing fsync, we have a race where we can end up either: 1) Attempt a fsync without holding the inode's lock, triggering an assertion failures when assertions are enabled; 2) Do an invalid memory access from the fsync task because the file private points to memory allocated on stack by the direct IO task and it may be used by the fsync task after the stack was destroyed. The race happens like this: 1) A user space program opens a file descriptor with O_DIRECT; 2) The program spawns 2 threads using libpthread for example; 3) One of the threads uses the file descriptor to do direct IO writes, while the other calls fsync using the same file descriptor. 4) Call task A the thread doing direct IO writes and task B the thread doing fsyncs; 5) Task A does a direct IO write, and at btrfs_direct_write() sets the file's private to an on stack allocated private with the member 'fsync_skip_inode_lock' set to true; 6) Task B enters btrfs_sync_file() and sees that there's a private structure associated to the file which has 'fsync_skip_inode_lock' set to true, so it skips locking the inode's vfs lock; 7) Task A completes the direct IO write, and resets the file's private to NULL since it had no prior private and our private was stack allocated. Then it unlocks the inode's vfs lock; 8) Task B enters btrfs_get_ordered_extents_for_logging(), then the assertion that checks the inode's vfs lock is held fails, since task B never locked it and task A has already unlocked it. The stack trace produced is the following: Aug 21 11:46:43 kerberos kernel: assertion failed: inode_is_locked(&inode->vfs_inode), in fs/btrfs/ordered-data.c:983 Aug 21 11:46:43 kerberos kernel: ------------[ cut here ]------------ Aug 21 11:46:43 kerberos kernel: kernel BUG at fs/btrfs/ordered-data.c:983!

This issue, triggering the assertion, was observed with QEMU workloads by two users in the Link tags below. Fix this by not relying on a file's private to pass information to fsync that it should skip locking the inode and instead pass this information through a special value stored in current->journal_info. This is safe because in the relevant section of the direct IO write path we are not holding a transaction handle, so current->journal_info is NULL.

[PATCH for 6.10 stable] btrfs: fix race between direct IO write and fsync when using same fd

by fdmanana＠kernel.org

From: Filipe Manana <fdmanana(a)suse.com> commit cd9253c23aedd61eb5ff11f37a36247cd46faf86 upstream. If we have 2 threads that are using the same file descriptor and one of them is doing direct IO writes while the other is doing fsync, we have a race where we can end up either: 1) Attempt a fsync without holding the inode's lock, triggering an assertion failures when assertions are enabled; 2) Do an invalid memory access from the fsync task because the file private points to memory allocated on stack by the direct IO task and it may be used by the fsync task after the stack was destroyed. The race happens like this: 1) A user space program opens a file descriptor with O_DIRECT; 2) The program spawns 2 threads using libpthread for example; 3) One of the threads uses the file descriptor to do direct IO writes, while the other calls fsync using the same file descriptor. 4) Call task A the thread doing direct IO writes and task B the thread doing fsyncs; 5) Task A does a direct IO write, and at btrfs_direct_write() sets the file's private to an on stack allocated private with the member 'fsync_skip_inode_lock' set to true; 6) Task B enters btrfs_sync_file() and sees that there's a private structure associated to the file which has 'fsync_skip_inode_lock' set to true, so it skips locking the inode's vfs lock; 7) Task A completes the direct IO write, and resets the file's private to NULL since it had no prior private and our private was stack allocated. Then it unlocks the inode's vfs lock; 8) Task B enters btrfs_get_ordered_extents_for_logging(), then the assertion that checks the inode's vfs lock is held fails, since task B never locked it and task A has already unlocked it. The stack trace produced is the following: Aug 21 11:46:43 kerberos kernel: assertion failed: inode_is_locked(&inode->vfs_inode), in fs/btrfs/ordered-data.c:983 Aug 21 11:46:43 kerberos kernel: ------------[ cut here ]------------ Aug 21 11:46:43 kerberos kernel: kernel BUG at fs/btrfs/ordered-data.c:983!

The following C program triggers the issue: $ cat repro.c /* Get the O_DIRECT definition. */ #ifndef _GNU_SOURCE #define _GNU_SOURCE #endif #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <stdint.h> #include <fcntl.h> #include <errno.h> #include <string.h> #include <pthread.h> static int fd; static ssize_t do_write(int fd, const void *buf, size_t count, off_t offset) { while (count > 0) { ssize_t ret; ret = pwrite(fd, buf, count, offset); if (ret < 0) { if (errno == EINTR) continue; return ret; } count -= ret; buf += ret; } return 0; } static void *fsync_loop(void *arg) { while (1) { int ret; ret = fsync(fd); if (ret != 0) { perror("Fsync failed"); exit(6); } } } int main(int argc, char *argv[]) { long pagesize; void *write_buf; pthread_t fsyncer; int ret; if (argc != 2) { fprintf(stderr, "Use: %s <file path>\n", argv[0]); return 1; } fd = open(argv[1], O_WRONLY | O_CREAT | O_TRUNC | O_DIRECT, 0666); if (fd == -1) { perror("Failed to open/create file"); return 1; } pagesize = sysconf(_SC_PAGE_SIZE); if (pagesize == -1) { perror("Failed to get page size"); return 2; } ret = posix_memalign(&write_buf, pagesize, pagesize); if (ret) { perror("Failed to allocate buffer"); return 3; } ret = pthread_create(&fsyncer, NULL, fsync_loop, NULL); if (ret != 0) { fprintf(stderr, "Failed to create writer thread: %d\n", ret); return 4; } while (1) { ret = do_write(fd, write_buf, pagesize, 0); if (ret != 0) { perror("Write failed"); exit(5); } } return 0; } $ mkfs.btrfs -f /dev/sdi $ mount /dev/sdi /mnt/sdi $ timeout 10 ./repro /mnt/sdi/foo Usually the race is triggered within less than 1 second.

[PATCHv6 3/4] x86/tdx: Dynamically disable SEPT violations from causing #VEs

by Kirill A. Shutemov

Memory access #VEs are hard for Linux to handle in contexts like the entry code or NMIs. But other OSes need them for functionality. There's a static (pre-guest-boot) way for a VMM to choose one or the other. But VMMs don't always know which OS they are booting, so they choose to deliver those #VEs so the "other" OSes will work. That, unfortunately has left us in the lurch and exposed to these hard-to-handle #VEs. The TDX module has introduced a new feature. Even if the static configuration is set to "send nasty #VEs", the kernel can dynamically request that they be disabled. Once they are disabled, access to private memory that is not in the Mapped state in the Secure-EPT (SEPT) will result in an exit to the VMM rather than injecting a #VE. Check if the feature is available and disable SEPT #VE if possible. If the TD is allowed to disable/enable SEPT #VEs, the ATTR_SEPT_VE_DISABLE attribute is no longer reliable. It reflects the initial state of the control for the TD, but it will not be updated if someone (e.g. bootloader) changes it before the kernel starts. Kernel must check TDCS_TD_CTLS bit to determine if SEPT #VEs are enabled or disabled. Signed-off-by: Kirill A.
