Commit [2] was merged shortly before [1], and their interaction was not handled properly. This resulted in IBPB not being triggered on VM-Exit in all SRSO mitigation configs requesting an IBPB there. Specifically, an IBPB on VM-Exit is triggered only when X86_FEATURE_IBPB_ON_VMEXIT is set. However: - X86_FEATURE_IBPB_ON_VMEXIT is not set for "spec_rstack_overflow=ibpb", because before [1] having X86_FEATURE_ENTRY_IBPB was enough. Hence, an IBPB is triggered on entry but the expected IBPB on VM-exit is not. - X86_FEATURE_IBPB_ON_VMEXIT is not set also when "spec_rstack_overflow=ibpb-vmexit" if X86_FEATURE_ENTRY_IBPB is already set. That's because before [1] this was effectively redundant. Hence, e.g. a "retbleed=ibpb spec_rstack_overflow=bpb-vmexit" config mistakenly reports the machine still vulnerable to SRSO, despite an IBPB being triggered both on entry and VM-Exit, because of the Retbleed selected mitigation config. - UNTRAIN_RET_VM won't still actually do anything unless CONFIG_MITIGATION_IBPB_ENTRY is set. For "spec_rstack_overflow=ibpb", enable IBPB on both entry and VM-Exit and clear X86_FEATURE_RSB_VMEXIT which is made superfluous by X86_FEATURE_IBPB_ON_VMEXIT. This effectively makes this mitigation option similar to the one for 'retbleed=ibpb', thus re-order the code for the RETBLEED_MITIGATION_IBPB option to be less confusing by having all features enabling before the disabling of the not needed ones. For "spec_rstack_overflow=ibpb-vmexit", guard this mitigation setting with CONFIG_MITIGATION_IBPB_ENTRY to ensure UNTRAIN_RET_VM sequence is effectively compiled in. Drop instead the CONFIG_MITIGATION_SRSO guard, since none of the SRSO compile cruft is required in this configuration. Also, check only that the required microcode is present to effectively enabled the IBPB on VM-Exit. Finally, update the KConfig description for CONFIG_MITIGATION_IBPB_ENTRY to list also all SRSO config settings enabled by this guard.

Commit [2] was merged shortly before [1], and their interaction was not handled properly. This resulted in IBPB not being triggered on VM-Exit in all SRSO mitigation configs requesting an IBPB there. Specifically, an IBPB on VM-Exit is triggered only when X86_FEATURE_IBPB_ON_VMEXIT is set. However: - X86_FEATURE_IBPB_ON_VMEXIT is not set for "spec_rstack_overflow=ibpb", because before [1] having X86_FEATURE_ENTRY_IBPB was enough. Hence, an IBPB is triggered on entry but the expected IBPB on VM-exit is not. - X86_FEATURE_IBPB_ON_VMEXIT is not set also when "spec_rstack_overflow=ibpb-vmexit" if X86_FEATURE_ENTRY_IBPB is already set. That's because before [1] this was effectively redundant. Hence, e.g. a "retbleed=ibpb spec_rstack_overflow=bpb-vmexit" config mistakenly reports the machine still vulnerable to SRSO, despite an IBPB being triggered both on entry and VM-Exit, because of the Retbleed selected mitigation config. - UNTRAIN_RET_VM won't still actually do anything unless CONFIG_MITIGATION_IBPB_ENTRY is set. For "spec_rstack_overflow=ibpb", enable IBPB on both entry and VM-Exit and clear X86_FEATURE_RSB_VMEXIT which is made superfluous by X86_FEATURE_IBPB_ON_VMEXIT. This effectively makes this mitigation option similar to the one for 'retbleed=ibpb', thus re-order the code for the RETBLEED_MITIGATION_IBPB option to be less confusing by having all features enabling before the disabling of the not needed ones. For "spec_rstack_overflow=ibpb-vmexit", guard this mitigation setting with CONFIG_MITIGATION_IBPB_ENTRY to ensure UNTRAIN_RET_VM sequence is effectively compiled in. Drop instead the CONFIG_MITIGATION_SRSO guard, since none of the SRSO compile cruft is required in this configuration. Also, check only that the required microcode is present to effectively enabled the IBPB on VM-Exit. Finally, update the KConfig description for CONFIG_MITIGATION_IBPB_ENTRY to list also all SRSO config settings enabled by this guard.

[PATCH v3 1/5] misc: pci_endpoint_test: Avoid issue of interrupts remaining after request_irq error

After devm_request_irq() fails with error in pci_endpoint_test_request_irq(), pci_endpoint_test_free_irq_vectors() is called assuming that all IRQs have been released. However some requested IRQs remain unreleased, so there are still /proc/irq/* entries remaining and we encounters WARN() with the following message: remove_proc_entry: removing non-empty directory 'irq/30', leaking at least 'pci-endpoint-test.0' WARNING: CPU: 0 PID: 202 at fs/proc/generic.c:719 remove_proc_entry +0x190/0x19c And show the call trace that led to this issue: [ 12.050005] Call trace: [ 12.051226] remove_proc_entry+0x190/0x19c (P) [ 12.053448] unregister_irq_proc+0xd0/0x104 [ 12.055541] free_desc+0x4c/0xd0 [ 12.057155] irq_free_descs+0x68/0x90 [ 12.058984] irq_domain_free_irqs+0x15c/0x1bc [ 12.061161] msi_domain_free_locked.part.0+0x184/0x1d4 [ 12.063728] msi_domain_free_irqs_all_locked+0x64/0x8c [ 12.066296] pci_msi_teardown_msi_irqs+0x48/0x54 [ 12.068604] pci_free_msi_irqs+0x18/0x38 [ 12.070564] pci_free_irq_vectors+0x64/0x8c [ 12.072654] pci_endpoint_test_ioctl+0x870/0x1068 [ 12.075006] __arm64_sys_ioctl+0xb0/0xe8 [ 12.076967] invoke_syscall+0x48/0x110 [ 12.078841] el0_svc_common.constprop.0+0x40/0xe8 [ 12.081192] do_el0_svc+0x20/0x2c [ 12.082848] el0_svc+0x30/0xd0 [ 12.084376] el0t_64_sync_handler+0x144/0x168 [ 12.086553] el0t_64_sync+0x198/0x19c [ 12.088383] ---[ end trace 0000000000000000 ]--- To solve this issue, set the number of remaining IRQs to test->num_irqs and release IRQs in advance by calling pci_endpoint_test_release_irq().

[PATCH v3] gpio: vf610: add locking to gpio direction functions

by Johan Korsnes

Add locking to `vf610_gpio_direction_input|output()` functions. Without this locking, a race condition exists between concurrent calls to these functions, potentially leading to incorrect GPIO direction settings. To verify the correctness of this fix, a `trylock` patch was applied, where after a couple of reboots the race was confirmed. I.e., one user had to wait before acquiring the lock. With this patch the race has not been encountered. It's worth mentioning that any type of debugging (printing, tracing, etc.) would "resolve"/hide the issue.

[PATCH 2/2] usb: typec: ucsi: increase timeout for PPM reset operations

by Fedor Pchelkin

It is observed that on some systems an initial PPM reset during the boot phase can trigger a timeout: [ 6.482546] ucsi_acpi USBC000:00: failed to reset PPM! [ 6.482551] ucsi_acpi USBC000:00: error -ETIMEDOUT: PPM init failed Still, increasing the timeout value, albeit being the most straightforward solution, eliminates the problem: the initial PPM reset may take up to ~8000-10000ms on some Lenovo laptops. When it is reset after the above period of time (or even if ucsi_reset_ppm() is not called overall), UCSI works as expected. Moreover, if the ucsi_acpi module is loaded/unloaded manually after the system has booted, reading the CCI values and resetting the PPM works perfectly, without any timeout. Thus it's only a boot-time issue. The reason for this behavior is not clear but it may be the consequence of some tricks that the firmware performs or be an actual firmware bug. As a workaround, increase the timeout to avoid failing the UCSI initialization prematurely.

[PATCH 1/2] acpi: typec: ucsi: Introduce a ->poll_cci method

by Fedor Pchelkin

From: "Christian A. Ehrhardt" <lk(a)c--e.de> For the ACPI backend of UCSI the UCSI "registers" are just a memory copy of the register values in an opregion. The ACPI implementation in the BIOS ensures that the opregion contents are synced to the embedded controller and it ensures that the registers (in particular CCI) are synced back to the opregion on notifications. While there is an ACPI call that syncs the actual registers to the opregion there is rarely a need to do this and on some ACPI implementations it actually breaks in various interesting ways. The only reason to force a sync from the embedded controller is to poll CCI while notifications are disabled. Only the ucsi core knows if this is the case and guessing based on the current command is suboptimal, i.e. leading to the following spurious assertion splat: WARNING: CPU: 3 PID: 76 at drivers/usb/typec/ucsi/ucsi.c:1388 ucsi_reset_ppm+0x1b4/0x1c0 [typec_ucsi] CPU: 3 UID: 0 PID: 76 Comm: kworker/3:0 Not tainted 6.12.11-200.fc41.x86_64 #1 Hardware name: LENOVO 21D0/LNVNB161216, BIOS J6CN45WW 03/17/2023 Workqueue: events_long ucsi_init_work [typec_ucsi] RIP: 0010:ucsi_reset_ppm+0x1b4/0x1c0 [typec_ucsi] Call Trace: <TASK> ucsi_init_work+0x3c/0xac0 [typec_ucsi] process_one_work+0x179/0x330 worker_thread+0x252/0x390 kthread+0xd2/0x100 ret_from_fork+0x34/0x50 ret_from_fork_asm+0x1a/0x30 </TASK> Thus introduce a ->poll_cci() method that works like ->read_cci() with an additional forced sync and document that this should be used when polling with notifications disabled. For all other backends that presumably don't have this issue use the same implementation for both methods.

[PATCH 1/2] dm-integrity: Avoid divide by zero in table status in Inline mode

by Milan Broz

In Inline mode, the journal is unused, and journal_sectors is zero. Calculating the journal watermark requires dividing by journal_sectors, which should be done only if the journal is configured. Otherwise, a simple table query (dmsetup table) can cause OOPS. This bug did not show on some systems, perhaps only due to compiler optimization. On my 32-bit testing machine, this reliably crashes with the following: : Oops: divide error: 0000 [#1] PREEMPT SMP : CPU: 0 UID: 0 PID: 2450 Comm: dmsetup Not tainted 6.14.0-rc2+ #959 : EIP: dm_integrity_status+0x2f8/0xab0 [dm_integrity] ...

[PATCH v6 RESEND] dt-bindings: iommu: mediatek: Fix interrupt count constraint for new SoCs

by Macpaul Lin

The infra-iommu node in mt8195.dtsi was triggering a CHECK_DTBS error due to an excessively long 'interrupts' property. The error message was: infra-iommu@10315000: interrupts: [[0, 795, 4, 0], [0, 796, 4, 0], [0, 797, 4, 0], [0, 798, 4, 0], [0, 799, 4, 0]] is too long To address this issue, update the compatbile matching rule for 'interrupts' property. This change allows flexibility in the number of interrupts for new SoCs like MT8195. The purpose of these 5 interrupts is also added into description.

[PATCH v2] PCI: fix reference leak in pci_register_host_bridge()

by Ma Ke

Once device_register() failed, we should call put_device() to decrement reference count for cleanup. Or it could cause memory leak. device_register() includes device_add(). As comment of device_add() says, 'if device_add() succeeds, you should call device_del() when you want to get rid of it. If device_add() has not succeeded, use only put_device() to drop the reference count'. Found by code review.

[PATCH v2 RESEND] phy: Fix error handling in tegra_xusb_port_init

by Ma Ke

If device_add() fails, do not use device_unregister() for error handling. device_unregister() consists two functions: device_del() and put_device(). device_unregister() should only be called after device_add() succeeded because device_del() undoes what device_add() does if successful. Change device_unregister() to put_device() call before returning from the function. As comment of device_add() says, 'if device_add() succeeds, you should call device_del() when you want to get rid of it. If device_add() has not succeeded, use only put_device() to drop the reference count'. Found by code review.

[PATCH] soc: qcom: pd-mapper: defer probing on sdm845

by Frank Oltmanns

On xiaomi-beryllium and oneplus-enchilada audio does not work reliably with the in-kernel pd-mapper. Deferring the probe solves these issues. Specifically, audio only works reliably with the in-kernel pd-mapper, if the probe succeeds when remoteproc3 triggers the first successful probe. I.e., probes from remoteproc0, 1, and 2 need to be deferred until remoteproc3 has been probed. Introduce a device specific quirk that lists the first auxdev for which the probe must be executed. Until then, defer probes from other auxdevs. Fixes: 1ebcde047c54 ("soc: qcom: add pd-mapper implementation") Cc: stable(a)vger.kernel.org Signed-off-by: Frank Oltmanns <frank(a)oltmanns.dev> --- The in-kernel pd-mapper has been causing audio issues on sdm845 devices (specifically, xiaomi-beryllium and oneplus-enchilada). I observed that Stephan’s approach [1] - which defers module probing by blocklisting the module and triggering a later probe - works reliably. Inspired by this, I experimented with delaying the probe within the module itself by returning -EPROBE_DEFER in qcom_pdm_probe() until a certain time (13.9 seconds after boot, based on ktime_get()) had elapsed. This method also restored audio functionality. Further logging of auxdev->id in qcom_pdm_probe() led to an interesting discovery: audio only works reliably with the in-kernel pd-mapper when the first successful probe is triggered by remoteproc3. In other words, probes from remoteproc0, 1, and 2 must be deferred until remoteproc3 has been probed. To address this, I propose introducing a quirk table (which currently only contains sdm845) to defer probing until the correct auxiliary device (remoteproc3) initiates the probe. I look forward to your feedback.

[for-linus][PATCH 5/5] ring-buffer: Update pages_touched to reflect persistent buffer content

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> The pages_touched field represents the number of subbuffers in the ring buffer that have content that can be read. This is used in accounting of "dirty_pages" and "buffer_percent" to allow the user to wait for the buffer to be filled to a certain amount before it reads the buffer in blocking mode. The persistent buffer never updated this value so it was set to zero, and this accounting would take it as it had no content. This would cause user space to wait for content even though there's enough content in the ring buffer that satisfies the buffer_percent.

It is rather trivial to allow this, but for now just disable mmap() of instances that have their ring buffer from the reserve_mem option. If an mmap() is performed on a persistent buffer it will return -ENODEV just like it would if the .mmap field wasn't defined in the file_operations structure.

[for-linus][PATCH 3/5] ring-buffer: Validate the persistent meta data subbuf array

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> The meta data for a mapped ring buffer contains an array of indexes of all the subbuffers. The first entry is the reader page, and the rest of the entries lay out the order of the subbuffers in how the ring buffer link list is to be created. The validator currently makes sure that all the entries are within the range of 0 and nr_subbufs. But it does not check if there are any duplicates. While working on the ring buffer, I corrupted this array, where I added duplicates. The validator did not catch it and created the ring buffer link list on top of it. Luckily, the corruption was only that the reader page was also in the writer path and only presented corrupted data but did not crash the kernel. But if there were duplicates in the writer side, then it could corrupt the ring buffer link list and cause a crash. Create a bitmask array with the size of the number of subbuffers. Then clear it. When walking through the subbuf array checking to see if the entries are within the range, test if its bit is already set in the subbuf_mask. If it is, then there is duplicates and fail the validation. If not, set the corresponding bit and continue.

[for-linus][PATCH 2/5] tracing: Have the error of __tracing_resize_ring_buffer() passed to user

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> Currently if __tracing_resize_ring_buffer() returns an error, the tracing_resize_ringbuffer() returns -ENOMEM. But it may not be a memory issue that caused the function to fail. If the ring buffer is memory mapped, then the resizing of the ring buffer will be disabled. But if the user tries to resize the buffer, it will get an -ENOMEM returned, which is confusing because there is plenty of memory. The actual error returned was -EBUSY, which would make much more sense to the user.

[PATCH 5.10] nvme-pci: fix multiple races in nvme_setup_io_queues

by Casey Chen

commit e4b9852a0f4afe40604afb442e3af4452722050a upstream. Below two paths could overlap each other if we power off a drive quickly after powering it on. There are multiple races in nvme_setup_io_queues() because of shutdown_lock missing and improper use of NVMEQ_ENABLED bit. nvme_reset_work() nvme_remove() nvme_setup_io_queues() nvme_dev_disable() ... ... A1 clear NVMEQ_ENABLED bit for admin queue lock retry: B1 nvme_suspend_io_queues() A2 pci_free_irq() admin queue B2 nvme_suspend_queue() admin queue A3 pci_free_irq_vectors() nvme_pci_disable() A4 nvme_setup_irqs(); B3 pci_free_irq_vectors() ... unlock A5 queue_request_irq() for admin queue set NVMEQ_ENABLED bit ... nvme_create_io_queues() A6 result = queue_request_irq(); set NVMEQ_ENABLED bit ... fail to allocate enough IO queues: A7 nvme_suspend_io_queues() goto retry If B3 runs in between A1 and A2, it will crash if irqaction haven't been freed by A2. B2 is supposed to free admin queue IRQ but it simply can't fulfill the job as A1 has cleared NVMEQ_ENABLED bit. Fix: combine A1 A2 so IRQ get freed as soon as the NVMEQ_ENABLED bit gets cleared. After solved #1, A2 could race with B3 if A2 is freeing IRQ while B3 is checking irqaction. A3 also could race with B2 if B2 is freeing IRQ while A3 is checking irqaction. Fix: A2 and A3 take lock for mutual exclusion. A3 could race with B3 since they could run free_msi_irqs() in parallel. Fix: A3 takes lock for mutual exclusion. A4 could fail to allocate all needed IRQ vectors if A3 and A4 are interrupted by B3. Fix: A4 takes lock for mutual exclusion. If A5/A6 happened after B2/B1, B3 will crash since irqaction is not NULL. They are just allocated by A5/A6. Fix: Lock queue_request_irq() and setting of NVMEQ_ENABLED bit. A7 could get chance to pci_free_irq() for certain IO queue while B3 is checking irqaction. Fix: A7 takes lock. nvme_dev->online_queues need to be protected by shutdown_lock. Since it is not atomic, both paths could modify it using its own copy.

+ revert-selftests-mm-remove-local-__nr_-definitions.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: Revert "selftests/mm: remove local __NR_* definitions" has been added to the -mm mm-hotfixes-unstable branch. Its filename is revert-selftests-mm-remove-local-__nr_-definitions.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: John Hubbard <jhubbard(a)nvidia.com> Subject: Revert "selftests/mm: remove local __NR_* definitions" Date: Thu, 13 Feb 2025 19:38:50 -0800 This reverts commit a5c6bc590094a1a73cf6fa3f505e1945d2bf2461. The general approach described in commit e076eaca5906 ("selftests: break the dependency upon local header files") was taken one step too far here: it should not have been extended to include the syscall numbers. This is because doing so would require per-arch support in tools/include/uapi, and no such support exists. This revert fixes two separate reports of test failures, from Dave Hansen[1], and Li Wang[2]. An excerpt of Dave's report: Before this commit (a5c6bc590094a1a73cf6fa3f505e1945d2bf2461) things are fine.

[PATCH v4 0/3] Fix broken SNP support with KVM module built-in

by Ashish Kalra

From: Ashish Kalra <ashish.kalra(a)amd.com> This patch-set fixes the current SNP host enabling code and effectively SNP which is broken with respect to the KVM module being built-in. Essentially SNP host enabling code should be invoked before KVM initialization, which is currently not the case when KVM is built-in. SNP host support is currently enabled in snp_rmptable_init() which is invoked as a device_initcall(). Here device_initcall() is used as snp_rmptable_init() expects AMD IOMMU SNP support to be enabled prior to it and the AMD IOMMU driver enables SNP support after PCI bus enumeration. This patch-set adds support to call snp_rmptable_init() early and directly from iommu_snp_enable() (after checking and enabling IOMMU SNP support) which enables SNP host support before KVM initialization with kvm_amd module built-in. Additionally the patch-set adds support to initialize PSP SEV driver during KVM module probe time. This patch-set has been tested with the following cases/scenarios: 1). kvm_amd module and PSP driver built-in. 2). kvm_amd module built-in with intremap=off kernel command line. 3). kvm_amd module built-in with iommu=off kernel command line. 4). kvm_amd and PSP driver built as modules. 5). kvm_amd built as module with iommu=off kernel command line. 6). kvm_amd module as built-in and PSP driver as module. 7). kvm_amd build as a module and PSP driver as built-in. v4: - Add warning if SNP support has been checked on IOMMUs and host SNP support has been enabled but late IOMMU initialization fails subsequently. - Add reviewed-by's. v3: - Ensure that dropping the device_initcall() happens in the same patch that wires up the IOMMU code to invoke snp_rmptable_init() which then makes sure that snp_rmptable_init() is still getting called and also merge patches 3 & 4. - Fix commit logs. v2: - Drop calling iommu_snp_enable() early before enabling IOMMUs as IOMMU subsystem gets initialized via subsys_initcall() and hence snp_rmptable_init() cannot be invoked via subsys_initcall(). - Instead add support to call snp_rmptable_init() early and directly via iommu_snp_enable(). - Fix commit logs.

[PATCH] gve: set xdp redirect target only when it is available

by joshwash＠google.com

From: Joshua Washington <joshwash(a)google.com> Before this patch the NETDEV_XDP_ACT_NDO_XMIT XDP feature flag is set by default as part of driver initialization, and is never cleared. However, this flag differs from others in that it is used as an indicator for whether the driver is ready to perform the ndo_xdp_xmit operation as part of an XDP_REDIRECT. Kernel helpers xdp_features_(set|clear)_redirect_target exist to convey this meaning. This patch ensures that the netdev is only reported as a redirect target when XDP queues exist to forward traffic.

[PATCH] partitions: mac: fix handling of bogus partition table

by Jann Horn

Fix several issues in partition probing: - The bailout for a bad partoffset must use put_dev_sector(), since the preceding read_part_sector() succeeded. - If the partition table claims a silly sector size like 0xfff bytes (which results in partition table entries straddling sector boundaries), bail out instead of accessing out-of-bounds memory. - We must not assume that the partition table contains proper NUL termination - use strnlen() and strncmp() instead of strlen() and strcmp().

[PATCH v2 0/4] soc: qcom: ice: fix dev reference leaked through of_qcom_ice_get

by Tudor Ambarus

Hi! Recently I've been pointed to this driver for an example on how consumers can get a pointer to the supplier's driver data and I noticed a leak. Callers of of_qcom_ice_get() leak the device reference taken by of_find_device_by_node(). Introduce devm_of_qcom_ice_get(). Exporting qcom_ice_put() is not done intentionally as the consumers need the ICE intance for the entire life of their device. Update the consumers to use the devm variant and make of_qcom_ice_get() static afterwards. This set touches mmc and scsi subsystems. Since the fix is trivial for them, I'd suggest taking everything through the SoC tree with Acked-by tags if people consider this fine. Note that the mmc and scsi patches depend on the first patch that introduces devm_of_qcom_ice_get(). Thanks!

[PATCH] clk: qcom: clk-branch: Fix invert halt status bit check for votable clocks

by Ajit Pandey

BRANCH_HALT_ENABLE and BRANCH_HALT_ENABLE_VOTED flags are used to check halt status of branch clocks, which have an inverted logic for the halt bit in CBCR register. However, the current logic in the _check_halt() method only compares the BRANCH_HALT_ENABLE flags, ignoring the votable branch clocks. Update the logic to correctly handle the invert logic for votable clocks using the BRANCH_HALT_ENABLE_VOTED flags.

[PATCH v3] soc: qcom: pdr: Fix the potential deadlock

by Mukesh Ojha

From: Saranya R <quic_sarar(a)quicinc.com> When some client process A call pdr_add_lookup() to add the look up for the service and does schedule locator work, later a process B got a new server packet indicating locator is up and call pdr_locator_new_server() which eventually sets pdr->locator_init_complete to true which process A sees and takes list lock and queries domain list but it will timeout due to deadlock as the response will queued to the same qmi->wq and it is ordered workqueue and process B is not able to complete new server request work due to deadlock on list lock. Fix it by removing the unnecessary list iteration as the list iteration is already being done inside locator work, so avoid it here and just call schedule_work() here. Process A Process B process_scheduled_works() pdr_add_lookup() qmi_data_ready_work() process_scheduled_works() pdr_locator_new_server() pdr->locator_init_complete=true; pdr_locator_work() mutex_lock(&pdr->list_lock); pdr_locate_service() mutex_lock(&pdr->list_lock); pdr_get_domain_list() pr_err("PDR: %s get domain list txn wait failed: %d\n", req->service_name, ret); Timeout error log due to deadlock: " PDR: tms/servreg get domain list txn wait failed: -110 PDR: service lookup for msm/adsp/sensor_pd:tms/servreg failed: -110 " Thanks to Bjorn and Johan for letting me know that this commit also fixes an audio regression when using the in-kernel pd-mapper as that makes it easier to hit this race.

[PATCH] firmware: qcom: uefisecapp: fix efivars registration race

by Johan Hovold

Since the conversion to using the TZ allocator, the efivars service is registered before the memory pool has been allocated, something which can lead to a NULL-pointer dereference in case of a racing EFI variable access. Make sure that all resources have been set up before registering the efivars. Fixes: 6612103ec35a ("firmware: qcom: qseecom: convert to using the TZ allocator") Cc: stable(a)vger.kernel.org # 6.11 Cc: Bartosz Golaszewski <bartosz.golaszewski(a)linaro.org> Signed-off-by: Johan Hovold <johan+linaro(a)kernel.org> --- Note that commit 40289e35ca52 ("firmware: qcom: scm: enable the TZ mem allocator") looks equally broken as it allocates the tzmem pool only after qcom_scm_is_available() returns true and other driver can start making SCM calls. That one appears to be a bit harder to fix as qcom_tzmem_enable() currently depends on SCM being available, but someone should definitely look into untangling that mess.

[PATCH v10 0/4] clk: qcom: Add support for multiple power-domains for a clock controller.

by Bryan O'Donoghue

Changes in v10: - Updated the commit log of patch #1 to make the reasoning - that it makes applying the subsequent patch cleaner/nicer clear - Bjorn - Substantially rewrites final patch commit to mostly reflect Bjorn's summation of my long and rambling previous paragraphs. Being a visual person, I've included some example pseudo-code which hopefully makes the intent clearer plus some ASCII art >= Klimt. - Link to v9: https://lore.kernel.org/r/20241230-b4-linux-next-24-11-18-clock-multiple-po… Changes in v9: - Added patch to unwind pm subdomains in reverse order. It would also be possible to squash this patch into patch#2 but, my own preference is for more granular patches like this instead of "slipping in" functional changes in larger patches like #2. - bod - Unwinding pm subdomain on error in patch #2. To facilitate this change patch #1 was created - Vlad - Drops Bjorn's RB on patch #2. There is a small churn in this patch but enough that a reviewer might reasonably expect RB to be given again. - Amends commit log for patch #3 further. v8 added a lot to the commit log to provide further information but, it is clear from the comments I received on the commit log that the added verbiage was occlusive not elucidative. Reduce down the commit log of patch #3 - especially Q&A item #1. Sometimes less is more. - Link to v8: https://lore.kernel.org/r/20241211-b4-linux-next-24-11-18-clock-multiple-po… Changes in v8: - Picks up change I agreed with Vlad but failed to cherry-pick into my b4 tree - Vlad/Bod - Rewords the commit log for patch #3. As I read it I decided I might translate bits of it from thought-stream into English - Bod - Link to v7: https://lore.kernel.org/r/20241211-b4-linux-next-24-11-18-clock-multiple-po… Changes in v7: - Expand commit log in patch #3 I've discussed with Bjorn on IRC and video what to put into the log here and captured most of what we discussed. Mostly the point here is voting for voltages in the power-domain list is up to the drivers to do with performance states/opp-tables not for the GDSC code. - Bjorn/Bryan - Link to v6: https://lore.kernel.org/r/20241129-b4-linux-next-24-11-18-clock-multiple-po… Changes in v6: - Passes NULL to second parameter of devm_pm_domain_attach_list - Vlad - Link to v5: https://lore.kernel.org/r/20241128-b4-linux-next-24-11-18-clock-multiple-po… Changes in v5: - In-lines devm_pm_domain_attach_list() in probe() directly - Vlad - Link to v4: https://lore.kernel.org/r/20241127-b4-linux-next-24-11-18-clock-multiple-po… v4: - Adds Bjorn's RB to first patch - Bjorn - Drops the 'd' in "and int" - Bjorn - Amends commit log of patch 3 to capture a number of open questions - Bjorn - Link to v3: https://lore.kernel.org/r/20241126-b4-linux-next-24-11-18-clock-multiple-po… v3: - Fixes commit log "per which" - Bryan - Link to v2: https://lore.kernel.org/r/20241125-b4-linux-next-24-11-18-clock-multiple-po… v2: The main change in this version is Bjorn's pointing out that pm_runtime_* inside of the gdsc_enable/gdsc_disable path would be recursive and cause a lockdep splat. Dmitry alluded to this too. Bjorn pointed to stuff being done lower in the gdsc_register() routine that might be a starting point. I iterated around that idea and came up with patch #3. When a gdsc has no parent and the pd_list is non-NULL then attach that orphan GDSC to the clock controller power-domain list. Existing subdomain code in gdsc_register() will connect the parent GDSCs in the clock-controller to the clock-controller subdomain, the new code here does that same job for a list of power-domains the clock controller depends on. To Dmitry's point about MMCX and MCX dependencies for the registers inside of the clock controller, I have switched off all references in a test dtsi and confirmed that accessing the clock-controller regs themselves isn't required. On the second point I also verified my test branch with lockdep on which was a concern with the pm_domain version of this solution but I wanted to cover it anyway with the new approach for completeness sake. Here's the item-by-item list of changes: - Adds a patch to capture pm_genpd_add_subdomain() result code - Bryan - Changes changelog of second patch to remove singleton and generally to make the commit log easier to understand - Bjorn - Uses demv_pm_domain_attach_list - Vlad - Changes error check to if (ret < 0 && ret != -EEXIST) - Vlad - Retains passing &pd_data instead of NULL - because NULL doesn't do the same thing - Bryan/Vlad - Retains standalone function qcom_cc_pds_attach() because the pd_data enumeration looks neater in a standalone function - Bryan/Vlad - Drops pm_runtime in favour of gdsc_add_subdomain_list() for each power-domain in the pd_list. The pd_list will be whatever is pointed to by power-domains = <> in the dtsi - Bjorn - Link to v1: https://lore.kernel.org/r/20241118-b4-linux-next-24-11-18-clock-multiple-po… v1: On x1e80100 and it's SKUs the Camera Clock Controller - CAMCC has multiple power-domains which power it. Usually with a single power-domain the core platform code will automatically switch on the singleton power-domain for you. If you have multiple power-domains for a device, in this case the clock controller, you need to switch those power-domains on/off yourself. The clock controllers can also contain Global Distributed Switch Controllers - GDSCs which themselves can be referenced from dtsi nodes ultimately triggering a gdsc_en() in drivers/clk/qcom/gdsc.c. As an example: cci0: cci@ac4a000 { power-domains = <&camcc TITAN_TOP_GDSC>; }; This series adds the support to attach a power-domain list to the clock-controllers and the GDSCs those controllers provide so that in the case of the above example gdsc_toggle_logic() will trigger the power-domain list with pm_runtime_resume_and_get() and pm_runtime_put_sync() respectively.

[PATCHSET 6.12] xfs: bug fixes from 6.13

by Darrick J. Wong

Hi all, Here's a bunch of hand-ported bug fixes for 6.12 LTS. Most of the patches fix a warning about dquot reclaim needing to read dquot buffers in from disk by pinning buffers at transaction commit time instead of during reclaim. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. With a bit of luck, this should all go splendidly. Comments and questions are, as always, welcome. --D kernel git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git/log/?h=ne… --- Commits in this patchset: * xfs: avoid nested calls to __xfs_trans_commit * xfs: don't lose solo superblock counter update transactions * xfs: don't lose solo dquot update transactions * xfs: separate dquot buffer reads from xfs_dqflush * xfs: clean up log item accesses in xfs_qm_dqflush{,_done} * xfs: attach dquot buffer to dquot log item buffer * xfs: convert quotacheck to attach dquot buffers * xfs: don't over-report free space or inodes in statvfs * xfs: release the dquot buf outside of qli_lock * xfs: lock dquot buffer before detaching dquot from b_li_list * xfs: fix mount hang during primary superblock recovery failure --- fs/xfs/xfs_dquot.h | 6 + fs/xfs/xfs_dquot_item.h | 7 + fs/xfs/xfs_quota.h | 7 + fs/xfs/xfs_buf_item_recover.c | 11 ++ fs/xfs/xfs_dquot.c | 199 +++++++++++++++++++++++++++++++++++------ fs/xfs/xfs_dquot_item.c | 51 ++++++++--- fs/xfs/xfs_qm.c | 48 ++++++++-- fs/xfs/xfs_qm_bhv.c | 27 ++++-- fs/xfs/xfs_trans.c | 39 ++++---- fs/xfs/xfs_trans_ail.c | 2 fs/xfs/xfs_trans_dquot.c | 31 +++++- 11 files changed, 338 insertions(+), 90 deletions(-)

[PATCH v2 1/7] ceph: Do not look at the index of an encrypted page

by Matthew Wilcox (Oracle)

If the pages array contains encrypted pages, we cannot look at page->index because that field is uninitialised. Instead, use the new ceph_fscrypt_pagecache_folio() to get the pagecache folio and look at the index of that.

[REGRESSION] usb: xhci port capability storage change broke fastboot android bootloader utility

by Forest

#regzbot introduced: 63a1f8454962 Dear maintainer, I think I have found a regression in kernels version 6.10 and newer, including the latest mainline v6.13-rc4: fastboot (the tool for communicating with Android bootloaders) now fails to perform various operations over USB. The problem manifests as an error when attempting to 'fastboot flash' an image (e.g. a new kernel containing security updates) to a LineageOS phone. It also manifests with simpler operations like reading a variable from the bootloader. For example: fastboot getvar kernel A typical error message when the failure occurs: getvar:kernel FAILED (remote: 'GetVar Variable Not found') I can reproduce this at will. It happens about 50% of the time when I run the above getvar command, and almost all the time when I try to push a new kernel to a device. A git bisect reveals this: 63a1f8454962a64746a59441687dc2401290326c is the first bad commit commit 63a1f8454962a64746a59441687dc2401290326c Author: Mathias Nyman <mathias.nyman(a)linux.intel.com> Date: Mon Apr 29 17:02:28 2024 +0300 xhci: stored cached port capability values in one place

[PATCH v2 01/11] drm/i915/dsi: Use TRANS_DDI_FUNC_CTL's own port width macro

The format of the port width field in the DDI_BUF_CTL and the TRANS_DDI_FUNC_CTL registers are different starting with MTL, where the x3 lane mode for HDMI FRL has a different encoding in the two registers.

[PATCH v6.13] fs/netfs/read_collect: fix crash due to uninitialized `prev` variable

When checking whether the edges of adjacent subrequests touch, the `prev` variable is deferenced, but it might not have been initialized. This causes crashes like this one: BUG: unable to handle page fault for address: 0000000181343843 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 8000001c66db0067 P4D 8000001c66db0067 PUD 0 Oops: Oops: 0000 [#1] SMP PTI CPU: 1 UID: 33333 PID: 24424 Comm: php-cgi8.2 Kdump: loaded Not tainted 6.13.2-cm4all0-hp+ #427 Hardware name: HP ProLiant DL380 Gen9/ProLiant DL380 Gen9, BIOS P89 11/23/2021 RIP: 0010:netfs_consume_read_data.isra.0+0x5ef/0xb00 Code: fe ff ff 48 8b 83 88 00 00 00 48 8b 4c 24 30 4c 8b 43 78 48 85 c0 48 8d 51 70 75 20 48 8b 73 30 48 39 d6 74 17 48 8b 7c 24 40 <48> 8b 4f 78 48 03 4f 68 48 39 4b 68 0f 84 ab 02 00 00 49 29 c0 48 RSP: 0000:ffffc90037adbd00 EFLAGS: 00010283 RAX: 0000000000000000 RBX: ffff88811bda0600 RCX: ffff888620e7b980 RDX: ffff888620e7b9f0 RSI: ffff88811bda0428 RDI: 00000001813437cb RBP: 0000000000000000 R08: 0000000000004000 R09: 0000000000000000 R10: ffffffff82e070c0 R11: 0000000007ffffff R12: 0000000000004000 R13: ffff888620e7bb68 R14: 0000000000008000 R15: ffff888620e7bb68 FS: 00007ff2e0e7ddc0(0000) GS:ffff88981f840000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000181343843 CR3: 0000001bc10ba006 CR4: 00000000001706f0 Call Trace: <TASK> ? __die+0x1f/0x60 ? page_fault_oops+0x15c/0x450 ? search_extable+0x22/0x30 ? netfs_consume_read_data.isra.0+0x5ef/0xb00 ? search_module_extables+0xe/0x40 ? exc_page_fault+0x5e/0x100 ? asm_exc_page_fault+0x22/0x30 ? netfs_consume_read_data.isra.0+0x5ef/0xb00 ? intel_iommu_unmap_pages+0xaa/0x190 ? __pfx_cachefiles_read_complete+0x10/0x10 netfs_read_subreq_terminated+0x24f/0x390 cachefiles_read_complete+0x48/0xf0 iomap_dio_bio_end_io+0x125/0x160 blk_update_request+0xea/0x3e0 scsi_end_request+0x27/0x190 scsi_io_completion+0x43/0x6c0 blk_complete_reqs+0x40/0x50 handle_softirqs+0xd1/0x280 irq_exit_rcu+0x91/0xb0 common_interrupt+0x3b/0xa0 asm_common_interrupt+0x22/0x40 RIP: 0033:0x55fe8470d2ab Code: 00 00 3c 7e 74 3b 3c b6 0f 84 dd 03 00 00 3c 1e 74 2f 83 c1 01 48 83 c2 38 48 83 c7 30 44 39 d1 74 3e 48 63 42 08 85 c0 79 a3 <49> 8b 46 48 8b 04 38 f6 c4 04 75 0b 0f b6 42 30 83 e0 0c 3c 04 75 RSP: 002b:00007ffca5ef2720 EFLAGS: 00000216 RAX: 0000000000000023 RBX: 0000000000000008 RCX: 000000000000001b RDX: 00007ff2e0cdb6f8 RSI: 0000000000000006 RDI: 0000000000000510 RBP: 00007ffca5ef27a0 R08: 00007ffca5ef2720 R09: 0000000000000001 R10: 000000000000001e R11: 00007ff2e0c10d08 R12: 0000000000000001 R13: 0000000000000120 R14: 00007ff2e0cb1ed0 R15: 00000000000000b0 </TASK> Fixes: ee4cdf7ba857 ("netfs: Speed up buffered reading") Cc: stable(a)vger.kernel.org Signed-off-by: Max Kellermann <max.kellermann(a)ionos.com> --- David/Greg: just like the other two netfs patches I sent yesterday, this one doesn't apply to v6.14 as it was obsoleted by commit e2d46f2ec332 ("netfs: Change the read result collector to only use one work item"). --- fs/netfs/read_collect.c | 22 ++++++++++++---------- 1 file changed, 12 insertions(+), 10 deletions(-) diff --git a/fs/netfs/read_collect.c b/fs/netfs/read_collect.c index e8624f5c7fcc..a7f285c52a79 100644 --- a/fs/netfs/read_collect.c +++ b/fs/netfs/read_collect.c @@ -258,17 +258,19 @@ static bool netfs_consume_read_data(struct netfs_io_subrequest *subreq, bool was */ if (!subreq->consumed && !prev_donated && - !list_is_first(&subreq->rreq_link, &rreq->subrequests) && - subreq->start == prev->start + prev->len) { + !list_is_first(&subreq->rreq_link, &rreq->subrequests)) { prev = list_prev_entry(subreq, rreq_link); - WRITE_ONCE(prev->next_donated, prev->next_donated + subreq->len); - subreq->start += subreq->len; - subreq->len = 0; - subreq->transferred = 0; - trace_netfs_donate(rreq, subreq, prev, subreq->len, - netfs_trace_donate_to_prev); - trace_netfs_sreq(subreq, netfs_sreq_trace_donate_to_prev); - goto remove_subreq_locked; + if (subreq->start == prev->start + prev->len) { + prev = list_prev_entry(subreq, rreq_link); + WRITE_ONCE(prev->next_donated, prev->next_donated + subreq->len); + subreq->start += subreq->len; + subreq->len = 0; + subreq->transferred = 0; + trace_netfs_donate(rreq, subreq, prev, subreq->len, + netfs_trace_donate_to_prev); + trace_netfs_sreq(subreq, netfs_sreq_trace_donate_to_prev); + goto remove_subreq_locked; + } } /* If we can't donate down the chain, donate up the chain instead. */ -- 2.47.2

[PATCH net] netdevsim: disable local BH when scheduling NAPI

The netdevsim driver was getting NOHZ tick-stop errors during packet transmission due to pending softirq work when calling napi_schedule(). This is showing the following message when running netconsole selftest. NOHZ tick-stop error: local softirq work is pending, handler #08!!! Add local_bh_disable()/enable() around the napi_schedule() call to prevent softirqs from being handled during this xmit.

[PATCH v2] phy: tegra: xusb: reset VBUS & ID OVERRIDE

by Henry Lin

From: BH Hsieh <bhsieh(a)nvidia.com> Observed VBUS_OVERRIDE & ID_OVERRIDE might be programmed with unexpected value prior to XUSB PADCTL driver, this could also occur in virtualization scenario. For example, UEFI firmware programs ID_OVERRIDE=GROUNDED to set a type-c port to host mode and keeps the value to kernel. If the type-c port is connected a usb host, below errors can be observed right after usb host mode driver gets probed. The errors would keep until usb role class driver detects the type-c port as device mode and notifies usb device mode driver to set both ID_OVERRIDE and VBUS_OVERRIDE to correct value by XUSB PADCTL driver. [ 173.765814] usb usb3-port2: Cannot enable. Maybe the USB cable is bad? [ 173.765837] usb usb3-port2: config error Taking virtualization into account, asserting XUSB PADCTL reset would break XUSB functions used by other guest OS, hence only reset VBUS & ID OVERRIDE of the port in utmi_phy_init.

[PATCH v6.13] fs/netfs/read_pgpriv2: skip folio queues without `marks3`

by Max Kellermann

At the beginning of the function, folio queues with marks3==0 are skipped, but after that, the `marks3` field is ignored. If one such queue is found, `slot` is set to 64 (because `__ffs(0)==64`), leading to a buffer overflow in the folioq_folio() call. The resulting crash may look like this: BUG: kernel NULL pointer dereference, address: 0000000000000000 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: Oops: 0000 [#1] SMP PTI CPU: 11 UID: 0 PID: 2909 Comm: kworker/u262:1 Not tainted 6.13.1-cm4all2-vm #415 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014 Workqueue: events_unbound netfs_read_termination_worker RIP: 0010:netfs_pgpriv2_write_to_the_cache+0x15a/0x3f0 Code: 48 85 c0 48 89 44 24 08 0f 84 24 01 00 00 48 8b 80 40 01 00 00 48 8b 7c 24 08 f3 48 0f bc c0 89 44 24 18 89 c0 48 8b 74 c7 08 <48> 8b 06 48 c7 04 24 00 10 00 00 a8 40 74 10 0f b6 4e 40 b8 00 10 RSP: 0018:ffffbbc440effe18 EFLAGS: 00010203 RAX: 0000000000000040 RBX: ffff96f8fc034000 RCX: 0000000000000000 RDX: 0000000000000040 RSI: 0000000000000000 RDI: ffff96f8fc036400 RBP: 0000000000001000 R08: ffff96f9132bb400 R09: 0000000000001000 R10: ffff96f8c1263c80 R11: 0000000000000003 R12: 0000000000001000 R13: ffff96f8fb75ade8 R14: fffffaaf5ca90000 R15: ffff96f8fb75ad00 FS: 0000000000000000(0000) GS:ffff9703cf0c0000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 000000010c9ca003 CR4: 00000000001706b0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: <TASK> ? __die+0x1f/0x60 ? page_fault_oops+0x158/0x450 ? search_extable+0x22/0x30 ? netfs_pgpriv2_write_to_the_cache+0x15a/0x3f0 ? search_module_extables+0xe/0x40 ? exc_page_fault+0x62/0x120 ? asm_exc_page_fault+0x22/0x30 ? netfs_pgpriv2_write_to_the_cache+0x15a/0x3f0 ? netfs_pgpriv2_write_to_the_cache+0xf6/0x3f0 netfs_read_termination_worker+0x1f/0x60 process_one_work+0x138/0x2d0 worker_thread+0x2a5/0x3b0 ? __pfx_worker_thread+0x10/0x10 kthread+0xba/0xe0 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x30/0x50 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1a/0x30 </TASK> Fixes: ee4cdf7ba857 ("netfs: Speed up buffered reading") Cc: stable(a)vger.kernel.org Signed-off-by: Max Kellermann <max.kellermann(a)ionos.com> --- Note this patch doesn't apply to v6.14 as it was obsoleted by commit e2d46f2ec332 ("netfs: Change the read result collector to only use one work item"). --- fs/netfs/read_pgpriv2.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/fs/netfs/read_pgpriv2.c b/fs/netfs/read_pgpriv2.c index 54d5004fec18..e72f5e674834 100644 --- a/fs/netfs/read_pgpriv2.c +++ b/fs/netfs/read_pgpriv2.c @@ -181,16 +181,17 @@ void netfs_pgpriv2_write_to_the_cache(struct netfs_io_request *rreq) break; folioq_unmark3(folioq, slot); - if (!folioq->marks3) { + while (!folioq->marks3) { folioq = folioq->next; if (!folioq) - break; + goto end_of_queue; } slot = __ffs(folioq->marks3); folio = folioq_folio(folioq, slot); } +end_of_queue: netfs_issue_write(wreq, &wreq->io_streams[1]); smp_wmb(); /* Write lists before ALL_QUEUED. */ set_bit(NETFS_RREQ_ALL_QUEUED, &wreq->flags); -- 2.47.2

The expectations are that when ID_AA64PFR0_EL1.SVE is 0, the ID_AA64ZFR0_EL1 register is also 0. So far, so good. Things become a bit more interesting if the HW implements SME. In this case, a few ID_AA64ZFR0_EL1 fields indicate *SME* features. And these fields overlap with their SVE interpretations. But the architecture says that the SME and SVE feature sets must match, so we're still hunky-dory. This goes wrong if the HW implements SME, but not SVE. In this case, we end-up advertising some SVE features to userspace, even if the HW has none. That's because we never consider whether SVE is actually implemented. Oh well. Fix it by restricting all SVE capabilities to ID_AA64PFR0_EL1.SVE being non-zero. The HWCAPS documentation is amended to reflect the actually checks performed by the kernel.

[PATCH v6] arm64: mm: Populate vmemmap/linear at the page level for hotplugged sections

by Zhenhua Huang

On the arm64 platform with 4K base page config, SECTION_SIZE_BITS is set to 27, making one section 128M. The related page struct which vmemmap points to is 2M then. Commit c1cc1552616d ("arm64: MMU initialisation") optimizes the vmemmap to populate at the PMD section level which was suitable initially since hot plug granule is always one section(128M). However, commit ba72b4c8cf60 ("mm/sparsemem: support sub-section hotplug") introduced a 2M(SUBSECTION_SIZE) hot plug granule, which disrupted the existing arm64 assumptions. Considering the vmemmap_free -> unmap_hotplug_pmd_range path, when pmd_sect() is true, the entire PMD section is cleared, even if there is other effective subsection. For example page_struct_map1 and page_strcut_map2 are part of a single PMD entry and they are hot-added sequentially. Then page_struct_map1 is removed, vmemmap_free() will clear the entire PMD entry freeing the struct page map for the whole section, even though page_struct_map2 is still active. Similar problem exists with linear mapping as well, for 16K base page(PMD size = 32M) or 64K base page(PMD = 512M), their block mappings exceed SUBSECTION_SIZE. Tearing down the entire PMD mapping too will leave other subsections unmapped in the linear mapping. To address the issue, we need to prevent PMD/PUD/CONT mappings for both linear and vmemmap for non-boot sections if corresponding size on the given base page exceeds SUBSECTION_SIZE(2MB now).

[PATCH RFC] usb: gadget: Set self-powered based on MaxPower and bmAttributes

by Prashanth K

Currently the USB gadget will be set as bus-powered based solely on whether its bMaxPower is greater than 100mA, but this may miss devices that may legitimately draw less than 100mA but still want to report as bus-powered. Similarly during suspend & resume, USB gadget is incorrectly marked as bus/self powered without checking the bmAttributes field. Fix these by configuring the USB gadget as self or bus powered based on bmAttributes, and explicitly set it as bus-powered if it draws more than 100mA.

[PATCH] usb: gadget: u_ether: Set is_suspend flag if remote wakeup fails

by Prashanth K

Currently while UDC suspends, u_ether attempts to remote wakeup the host if there are any pending transfers. However, if remote wakeup fails, the UDC remains suspended but the is_suspend flag is not set. And since is_suspend flag isn't set, the subsequent eth_start_xmit() would queue USB requests to suspended UDC. To fix this, bail out from gether_suspend() only if remote wakeup operation is successful.

[PATCH] Revert "selftests/mm: remove local __NR_* definitions"

by John Hubbard

This reverts commit a5c6bc590094a1a73cf6fa3f505e1945d2bf2461. The general approach described in commit e076eaca5906 ("selftests: break the dependency upon local header files") was taken one step too far here: it should not have been extended to include the syscall numbers. This is because doing so would require per-arch support in tools/include/uapi, and no such support exists. This revert fixes two separate reports of test failures, from Dave Hansen[1], and Li Wang[2]. An excerpt of Dave's report: Before this commit (a5c6bc590094a1a73cf6fa3f505e1945d2bf2461) things are fine.

[PATCH 5.10] scsi: core: Fix scsi_mode_sense() buffer length handling

by Vasiliy Kovalev

From: Damien Le Moal <damien.lemoal(a)wdc.com> commit 17b49bcbf8351d3dbe57204468ac34f033ed60bc upstream. Several problems exist with scsi_mode_sense() buffer length handling: 1) The allocation length field of the MODE SENSE(10) command is 16-bits, occupying bytes 7 and 8 of the CDB. With this command, access to mode pages larger than 255 bytes is thus possible. However, the CDB allocation length field is set by assigning len to byte 8 only, thus truncating buffer length larger than 255. 2) If scsi_mode_sense() is called with len smaller than 8 with sdev->use_10_for_ms set, or smaller than 4 otherwise, the buffer length is increased to 8 and 4 respectively, and the buffer is zero filled with these increased values, thus corrupting the memory following the buffer. Fix these 2 problems by using put_unaligned_be16() to set the allocation length field of MODE SENSE(10) CDB and by returning an error when len is too small. Furthermore, if len is larger than 255B, always try MODE SENSE(10) first, even if the device driver did not set sdev->use_10_for_ms. In case of invalid opcode error for MODE SENSE(10), access to mode pages larger than 255 bytes are not retried using MODE SENSE(6). To avoid buffer length overflows for the MODE_SENSE(10) case, check that len is smaller than 65535 bytes. While at it, also fix the folowing: * Use get_unaligned_be16() to retrieve the mode data length and block descriptor length fields of the mode sense reply header instead of using an open coded calculation. * Fix the kdoc dbd argument explanation: the DBD bit stands for Disable Block Descriptor, which is the opposite of what the dbd argument description was.

[PATCH] net: dsa: felix: Add NULL check for outer_tagging_rule()

by Wentao Liang

In felix_update_tag_8021q_rx_rules(), the return value of ocelot_vcap_block_find_filter_by_id() is not checked, which could lead to a NULL pointer dereference if the filter is not found. Add the necessary check and use `continue` to skip the current CPU port if the filter is not found, ensuring that all CPU ports are processed.

If the SCSI command doesn't carry payload, the driver may use this value as is for communicating with host, resulting in possible corruption. Fix this by always initializing this value.

[PATCH] arm64: rust: clean Rust 1.85.0 warning using softfloat target

by Miguel Ojeda

Starting with Rust 1.85.0 (to be released 2025-02-20), `rustc` warns [1] about disabling neon in the aarch64 hardfloat target: warning: target feature `neon` cannot be toggled with `-Ctarget-feature`: unsound on hard-float targets because it changes float ABI | = note: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release! = note: for more information, see issue #116344 <https://github.com/rust-lang/rust/issues/116344> Thus, instead, use the softfloat target instead. While trying it out, I found that the kernel sanitizers were not enabled for that built-in target [2]. Upstream Rust agreed to backport the enablement for the current beta so that it is ready for the 1.85.0 release [3] -- thanks! However, that still means that before Rust 1.85.0, we cannot switch since sanitizers could be in use. Thus conditionally do so.

Thanks! I would like to get this one into -rc3 if possible so that by the time the compiler releases we are already clean.

[PATCH] drm/xe/userptr: fix EFAULT handling

by Matthew Auld

Currently we treat EFAULT from hmm_range_fault() as a non-fatal error when called from xe_vm_userptr_pin() with the idea that we want to avoid killing the entire vm and chucking an error, under the assumption that the user just did an unmap or something, and has no intention of actually touching that memory from the GPU. At this point we have already zapped the PTEs so any access should generate a page fault, and if the pin fails there also it will then become fatal. However it looks like it's possible for the userptr vma to still be on the rebind list in preempt_rebind_work_func(), if we had to retry the pin again due to something happening in the caller before we did the rebind step, but in the meantime needing to re-validate the userptr and this time hitting the EFAULT. This might explain an internal user report of hitting: [ 191.738349] WARNING: CPU: 1 PID: 157 at drivers/gpu/drm/xe/xe_res_cursor.h:158 xe_pt_stage_bind.constprop.0+0x60a/0x6b0 [xe] [ 191.738551] Workqueue: xe-ordered-wq preempt_rebind_work_func [xe] [ 191.738616] RIP: 0010:xe_pt_stage_bind.constprop.0+0x60a/0x6b0 [xe] [ 191.738690] Call Trace: [ 191.738692] <TASK> [ 191.738694] ? show_regs+0x69/0x80 [ 191.738698] ? __warn+0x93/0x1a0 [ 191.738703] ? xe_pt_stage_bind.constprop.0+0x60a/0x6b0 [xe] [ 191.738759] ? report_bug+0x18f/0x1a0 [ 191.738764] ? handle_bug+0x63/0xa0 [ 191.738767] ? exc_invalid_op+0x19/0x70 [ 191.738770] ? asm_exc_invalid_op+0x1b/0x20 [ 191.738777] ? xe_pt_stage_bind.constprop.0+0x60a/0x6b0 [xe] [ 191.738834] ? ret_from_fork_asm+0x1a/0x30 [ 191.738849] bind_op_prepare+0x105/0x7b0 [xe] [ 191.738906] ? dma_resv_reserve_fences+0x301/0x380 [ 191.738912] xe_pt_update_ops_prepare+0x28c/0x4b0 [xe] [ 191.738966] ? kmemleak_alloc+0x4b/0x80 [ 191.738973] ops_execute+0x188/0x9d0 [xe] [ 191.739036] xe_vm_rebind+0x4ce/0x5a0 [xe] [ 191.739098] ? trace_hardirqs_on+0x4d/0x60 [ 191.739112] preempt_rebind_work_func+0x76f/0xd00 [xe] Followed by NPD, when running some workload, since the sg was never actually populated but the vma is still marked for rebind when it should be skipped for this special EFAULT case.

[PATCH] gpiolib: protect gpio_chip with SRCU in array_info paths in multi get/set

by Bartosz Golaszewski

From: Bartosz Golaszewski <bartosz.golaszewski(a)linaro.org> During the locking rework in GPIOLIB, we omitted one important use-case, namely: setting and getting values for GPIO descriptor arrays with array_info present. This patch does two things: first it makes struct gpio_array store the address of the underlying GPIO device and not chip. Next: it protects the chip with SRCU from removal in gpiod_get_array_value_complex() and gpiod_set_array_value_complex().

[PATCH V4 2/4] x86/tdx: Route safe halt execution via tdx_safe_halt()

by Vishal Annapurve

Direct HLT instruction execution causes #VEs for TDX VMs which is routed to hypervisor via TDCALL. safe_halt() routines execute HLT in STI-shadow so IRQs need to remain disabled until the TDCALL to ensure that pending IRQs are correctly treated as wake events. So "sti;hlt" sequence needs to be replaced with "TDCALL; raw_local_irq_enable()" for TDX VMs. Commit bfe6ed0c6727 ("x86/tdx: Add HLT support for TDX guests") prevented the idle routines from using "sti;hlt". But it missed the paravirt routine which can be reached like this as an example: acpi_safe_halt() => raw_safe_halt() => arch_safe_halt() => irq.safe_halt() => pv_native_safe_halt() Modify tdx_safe_halt() to implement the sequence "TDCALL; raw_local_irq_enable()" and invoke tdx_halt() from idle routine which just executes TDCALL without changing state of interrupts. Introduce dependency on CONFIG_PARAVIRT and override paravirt halt()/safe_halt() routines for TDX VMs. Cc: stable(a)vger.kernel.org Fixes: bfe6ed0c6727 ("x86/tdx: Add HLT support for TDX guests") Signed-off-by: Vishal Annapurve <vannapurve(a)google.com> --- arch/x86/Kconfig | 1 + arch/x86/coco/tdx/tdx.c | 18 +++++++++++++++++- arch/x86/include/asm/tdx.h | 2 +- arch/x86/kernel/process.c | 2 +- 4 files changed, 20 insertions(+), 3 deletions(-) diff --git a/arch/x86/Kconfig b/arch/x86/Kconfig index 87198d957e2f..afcdbc9693dc 100644 --- a/arch/x86/Kconfig +++ b/arch/x86/Kconfig @@ -902,6 +902,7 @@ config INTEL_TDX_GUEST depends on X86_64 && CPU_SUP_INTEL depends on X86_X2APIC depends on EFI_STUB + depends on PARAVIRT select ARCH_HAS_CC_PLATFORM select X86_MEM_ENCRYPT select X86_MCE diff --git a/arch/x86/coco/tdx/tdx.c b/arch/x86/coco/tdx/tdx.c index 32809a06dab4..ee67c1870e70 100644 --- a/arch/x86/coco/tdx/tdx.c +++ b/arch/x86/coco/tdx/tdx.c @@ -14,6 +14,7 @@ #include <asm/ia32.h> #include <asm/insn.h> #include <asm/insn-eval.h> +#include <asm/paravirt_types.h> #include <asm/pgtable.h> #include <asm/set_memory.h> #include <asm/traps.h> @@ -398,7 +399,7 @@ static int handle_halt(struct ve_info *ve) return ve_instr_len(ve); } -void __cpuidle tdx_safe_halt(void) +void __cpuidle tdx_halt(void) { const bool irq_disabled = false; @@ -409,6 +410,12 @@ void __cpuidle tdx_safe_halt(void) WARN_ONCE(1, "HLT instruction emulation failed\n"); } +static void __cpuidle tdx_safe_halt(void) +{ + tdx_halt(); + raw_local_irq_enable(); +} + static int read_msr(struct pt_regs *regs, struct ve_info *ve) { struct tdx_module_args args = { @@ -1109,6 +1116,15 @@ void __init tdx_early_init(void) x86_platform.guest.enc_kexec_begin = tdx_kexec_begin; x86_platform.guest.enc_kexec_finish = tdx_kexec_finish; + /* + * "sti;hlt" execution in TDX guests will induce a #VE in the STI-shadow + * which will enable interrupts before HLT TDCALL inocation possibly + * resulting in missed wakeup events.

[PATCH] drm: panel: jd9365da-h3: fix reset signal polarity

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> In jadard_prepare() a reset pulse is generated with the following statements (delays ommited for clarity): gpiod_set_value(jadard->reset, 1); --> Deassert reset gpiod_set_value(jadard->reset, 0); --> Assert reset for 10ms gpiod_set_value(jadard->reset, 1); --> Deassert reset However, specifying second argument of "0" to gpiod_set_value() means to deassert the GPIO, and "1" means to assert it. If the reset signal is defined as GPIO_ACTIVE_LOW in the DTS, the above statements will incorrectly generate the reset pulse (inverted) and leave it asserted (LOW) at the end of jadard_prepare(). Fix reset behavior by inverting gpiod_set_value() second argument in jadard_prepare(). Also modify second argument to devm_gpiod_get() in jadard_dsi_probe() to assert the reset when probing. Do not modify it in jadard_unprepare() as it is already properly asserted with "1", which seems to be the intended behavior.

[PATCH 0/2] acct: don't allow access to internal filesystems

by Christian Brauner

In [1] it was reported that the acct(2) system call can be used to trigger a NULL deref in cases where it is set to write to a file that triggers an internal lookup. This can e.g., happen when pointing acct(2) to /sys/power/resume. At the point the where the write to this file happens the calling task has already exited and called exit_fs() but an internal lookup might be triggered through lookup_bdev(). This may trigger a NULL-deref when accessing current->fs. This series does two things: - Reorganize the code so that the the final write happens from the workqueue but with the caller's credentials. This preserves the (strange) permission model and has almost no regression risk. - Block access to kernel internal filesystems as well as procfs and sysfs in the first place. This api should stop to exist imho.

So this commit: 3ec920bb978c ("selftests: rtnetlink: update netdevsim ipsec output format") which is not backported to stable kernels tries to address rtneltlink.sh fixing. fixes the change in handling tx ip address as well, so far so good! but when I apply this script fix it doesn't pass yet: 2c2 < sa[0] tx ipaddr=0x00000000 00000000 00000000 047ba8c0 --- > sa[0] tx ipaddr=192.168.123.4 5c5 < sa[1] rx ipaddr=0x00000000 00000000 00000000 037ba8c0 --- > sa[1] rx ipaddr=192.168.123.3 FAIL: ipsec_offload incorrect driver data So it clearly suggest that addresses are not properly handled, IPSec addresses are printed in hexadecimal format, but the script expects it in more readable format, that hinted me whats missing, and that commit is: commit c71bc6da6198a6d88df86094f1052bb581951d65 Author: Hangbin Liu <liuhangbin(a)gmail.com> Date: Thu Oct 10 04:00:25 2024 +0000 netdevsim: print human readable IP address Currently, IPSec addresses are printed in hexadecimal format, which is not user-friendly. e.g. # cat /sys/kernel/debug/netdevsim/netdevsim0/ports/0/ipsec SA count=2 tx=20 sa[0] rx ipaddr=0x00000000 00000000 00000000 0100a8c0 sa[0] spi=0x00000101 proto=0x32 salt=0x0adecc3a crypt=1 sa[0] key=0x3167608a ca4f1397 43565909 941fa627 sa[1] tx ipaddr=0x00000000 00000000 00000000 00000000 sa[1] spi=0x00000100 proto=0x32 salt=0x0adecc3a crypt=1 sa[1] key=0x3167608a ca4f1397 43565909 941fa627 This patch updates the code to print the IPSec address in a human-readable format for easier debug. e.g. # cat /sys/kernel/debug/netdevsim/netdevsim0/ports/0/ipsec SA count=4 tx=40 sa[0] tx ipaddr=0.0.0.0 sa[0] spi=0x00000100 proto=0x32 salt=0x0adecc3a crypt=1 sa[0] key=0x3167608a ca4f1397 43565909 941fa627 sa[1] rx ipaddr=192.168.0.1 sa[1] spi=0x00000101 proto=0x32 salt=0x0adecc3a crypt=1 sa[1] key=0x3167608a ca4f1397 43565909 941fa627 sa[2] tx ipaddr=:: sa[2] spi=0x00000100 proto=0x32 salt=0x0adecc3a crypt=1 sa[2] key=0x3167608a ca4f1397 43565909 941fa627 sa[3] rx ipaddr=2000::1 sa[3] spi=0x00000101 proto=0x32 salt=0x0adecc3a crypt=1 sa[3] key=0x3167608a ca4f1397 43565909 941fa627 Solution: ======== Backport both the commits commit: c71bc6da6198 ("netdevsim: print human readable IP address") and script fixup commit: 3ec920bb978c ("selftests: rtnetlink: update netdevsim ipsec output format") to all stable kernels which have commit: 2cf567f421db ("netdevsim: copy addresses for both in and out paths") in them. Another clue to say this is right way to do this is that these above three patches did go as patchset into net/ [1]. I am sending patches for all stable trees differently, however I am using same cover letter. Tested all stable kernels after patching. This failure is no more reproducible.

[PATCH 6.1.y] nfsd: release svc_expkey/svc_export with rcu_work

by lanbincn＠qq.com

From: Yang Erkun <yangerkun(a)huawei.com> commit f8c989a0c89a75d30f899a7cabdc14d72522bb8d upstream. The last reference for `cache_head` can be reduced to zero in `c_show` and `e_show`(using `rcu_read_lock` and `rcu_read_unlock`). Consequently, `svc_export_put` and `expkey_put` will be invoked, leading to two issues: 1. The `svc_export_put` will directly free ex_uuid. However, `e_show`/`c_show` will access `ex_uuid` after `cache_put`, which can trigger a use-after-free issue, shown below. ================================================================== BUG: KASAN: slab-use-after-free in svc_export_show+0x362/0x430 [nfsd] Read of size 1 at addr ff11000010fdc120 by task cat/870 CPU: 1 UID: 0 PID: 870 Comm: cat Not tainted 6.12.0-rc3+ #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.1-2.fc37 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x53/0x70 print_address_description.constprop.0+0x2c/0x3a0 print_report+0xb9/0x280 kasan_report+0xae/0xe0 svc_export_show+0x362/0x430 [nfsd] c_show+0x161/0x390 [sunrpc] seq_read_iter+0x589/0x770 seq_read+0x1e5/0x270 proc_reg_read+0xe1/0x140 vfs_read+0x125/0x530 ksys_read+0xc1/0x160 do_syscall_64+0x5f/0x170 entry_SYSCALL_64_after_hwframe+0x76/0x7e Allocated by task 830: kasan_save_stack+0x20/0x40 kasan_save_track+0x14/0x30 __kasan_kmalloc+0x8f/0xa0 __kmalloc_node_track_caller_noprof+0x1bc/0x400 kmemdup_noprof+0x22/0x50 svc_export_parse+0x8a9/0xb80 [nfsd] cache_do_downcall+0x71/0xa0 [sunrpc] cache_write_procfs+0x8e/0xd0 [sunrpc] proc_reg_write+0xe1/0x140 vfs_write+0x1a5/0x6d0 ksys_write+0xc1/0x160 do_syscall_64+0x5f/0x170 entry_SYSCALL_64_after_hwframe+0x76/0x7e Freed by task 868: kasan_save_stack+0x20/0x40 kasan_save_track+0x14/0x30 kasan_save_free_info+0x3b/0x60 __kasan_slab_free+0x37/0x50 kfree+0xf3/0x3e0 svc_export_put+0x87/0xb0 [nfsd] cache_purge+0x17f/0x1f0 [sunrpc] nfsd_destroy_serv+0x226/0x2d0 [nfsd] nfsd_svc+0x125/0x1e0 [nfsd] write_threads+0x16a/0x2a0 [nfsd] nfsctl_transaction_write+0x74/0xa0 [nfsd] vfs_write+0x1a5/0x6d0 ksys_write+0xc1/0x160 do_syscall_64+0x5f/0x170 entry_SYSCALL_64_after_hwframe+0x76/0x7e 2. We cannot sleep while using `rcu_read_lock`/`rcu_read_unlock`.

[PATCH] ACPI: GTDT: Relax sanity checking on Platform Timers array count

by Oliver Upton

Perhaps unsurprisingly there are some platforms where the GTDT isn't quite right and the Platforms Timer array overflows the length of the overall table. While the recently-added sanity checking isn't wrong, it makes it impossible to boot the kernel on offending platforms. Try to hobble along and limit the Platform Timer count to the bounds of the table.

[PATCH 1/2] drm/xe/userptr: fix EFAULT handling

by Matthew Auld

Currently we treat EFAULT from hmm_range_fault() as a non-fatal error when called from xe_vm_userptr_pin() with the idea that we want to avoid killing the entire vm and chucking an error, under the assumption that the user just did an unmap or something, and has no intention of actually touching that memory from the GPU. At this point we have already zapped the PTEs so any access should generate a page fault, and if the pin fails there also it will then become fatal. However it looks like it's possible for the userptr vma to still be on the rebind list in preempt_rebind_work_func(), if we had to retry the pin again due to something happening in the caller before we did the rebind step, but in the meantime needing to re-validate the userptr and this time hitting the EFAULT. This might explain an internal user report of hitting: [ 191.738349] WARNING: CPU: 1 PID: 157 at drivers/gpu/drm/xe/xe_res_cursor.h:158 xe_pt_stage_bind.constprop.0+0x60a/0x6b0 [xe] [ 191.738551] Workqueue: xe-ordered-wq preempt_rebind_work_func [xe] [ 191.738616] RIP: 0010:xe_pt_stage_bind.constprop.0+0x60a/0x6b0 [xe] [ 191.738690] Call Trace: [ 191.738692] <TASK> [ 191.738694] ? show_regs+0x69/0x80 [ 191.738698] ? __warn+0x93/0x1a0 [ 191.738703] ? xe_pt_stage_bind.constprop.0+0x60a/0x6b0 [xe] [ 191.738759] ? report_bug+0x18f/0x1a0 [ 191.738764] ? handle_bug+0x63/0xa0 [ 191.738767] ? exc_invalid_op+0x19/0x70 [ 191.738770] ? asm_exc_invalid_op+0x1b/0x20 [ 191.738777] ? xe_pt_stage_bind.constprop.0+0x60a/0x6b0 [xe] [ 191.738834] ? ret_from_fork_asm+0x1a/0x30 [ 191.738849] bind_op_prepare+0x105/0x7b0 [xe] [ 191.738906] ? dma_resv_reserve_fences+0x301/0x380 [ 191.738912] xe_pt_update_ops_prepare+0x28c/0x4b0 [xe] [ 191.738966] ? kmemleak_alloc+0x4b/0x80 [ 191.738973] ops_execute+0x188/0x9d0 [xe] [ 191.739036] xe_vm_rebind+0x4ce/0x5a0 [xe] [ 191.739098] ? trace_hardirqs_on+0x4d/0x60 [ 191.739112] preempt_rebind_work_func+0x76f/0xd00 [xe] Followed by NPD, when running some workload, since the sg was never actually populated but the vma is still marked for rebind when it should be skipped for this special EFAULT case.

[PATCH RFC 1/2] acpi: typec: ucsi: Introduce a ->poll_cci method

by Fedor Pchelkin

From: "Christian A. Ehrhardt" <lk(a)c--e.de> For the ACPI backend of UCSI the UCSI "registers" are just a memory copy of the register values in an opregion. The ACPI implementation in the BIOS ensures that the opregion contents are synced to the embedded controller and it ensures that the registers (in particular CCI) are synced back to the opregion on notifications. While there is an ACPI call that syncs the actual registers to the opregion there is rarely a need to do this and on some ACPI implementations it actually breaks in various interesting ways. The only reason to force a sync from the embedded controller is to poll CCI while notifications are disabled. Only the ucsi core knows if this is the case and guessing based on the current command is suboptimal, i.e. leading to the following spurious assertion splat: WARNING: CPU: 3 PID: 76 at drivers/usb/typec/ucsi/ucsi.c:1388 ucsi_reset_ppm+0x1b4/0x1c0 [typec_ucsi] CPU: 3 UID: 0 PID: 76 Comm: kworker/3:0 Not tainted 6.12.11-200.fc41.x86_64 #1 Hardware name: LENOVO 21D0/LNVNB161216, BIOS J6CN45WW 03/17/2023 Workqueue: events_long ucsi_init_work [typec_ucsi] RIP: 0010:ucsi_reset_ppm+0x1b4/0x1c0 [typec_ucsi] Call Trace: <TASK> ucsi_init_work+0x3c/0xac0 [typec_ucsi] process_one_work+0x179/0x330 worker_thread+0x252/0x390 kthread+0xd2/0x100 ret_from_fork+0x34/0x50 ret_from_fork_asm+0x1a/0x30 </TASK> Thus introduce a ->poll_cci() method that works like ->read_cci() with an additional forced sync and document that this should be used when polling with notifications disabled. For all other backends that presumably don't have this issue use the same implementation for both methods.

[PATCH v2, 1/1] usb: typec: tcpm: PSSourceOffTimer timeout in PR_Swap enters ERROR_RECOVERY

by joswang

From: Jos Wang <joswang(a)lenovo.com> As PD2.0 spec ("6.5.6.2 PSSourceOffTimer")，the PSSourceOffTimer is used by the Policy Engine in Dual-Role Power device that is currently acting as a Sink to timeout on a PS_RDY Message during a Power Role Swap sequence. This condition leads to a Hard Reset for USB Type-A and Type-B Plugs and Error Recovery for Type-C plugs and return to USB Default Operation. Therefore, after PSSourceOffTimer timeout, the tcpm state machine should switch from PR_SWAP_SNK_SRC_SINK_OFF to ERROR_RECOVERY.

FW: [PATCH] usb: xhci: lack of clearing xHC resources

by Pawel Laszczak

The xHC resources allocated for USB devices are not released in correct order after resuming in case when while suspend device was reconnected. This issue has been detected during the fallowing scenario: - connect hub HS to root port - connect LS/FS device to hub port - wait for enumeration to finish - force DUT to suspend - reconnect hub attached to root port - wake DUT For this scenario during enumeration of USB LS/FS device the Cadence xHC reports completion error code for xHCi commands because the devices was not property disconnected and in result the xHC resources has not been correct freed. XHCI specification doesn't mention that device can be reset in any order so, we should not treat this issue as Cadence xHC controller bug. Similar as during disconnecting in this case the device should be cleared starting form the last usb device in tree toward the root hub. To fix this issue usbcore driver should disconnect all USB devices connected to hub which was reconnected while suspending.

This patch (of 3): The current calculation for splitting nodes tries to enforce a minimum span on the leaf nodes. This code is complex and never worked correctly to begin with, due to the min value being passed as 0 for all leaves. The calculation should just split the data as equally as possible between the new nodes. Note that b_end will be one more than the data, so the left side is still favoured in the calculation. The current code may also lead to a deficient node by not leaving enough data for the right side of the split. This issue is also addressed with the split calculation change.

[PATCH v6.6-v6.1] x86/mm/ident_map: Use gbpages only where full GB page should be mapped.

by hsimeliere.opensource＠witekio.com

From: Steve Wahl <steve.wahl(a)hpe.com> [ Upstream commit cc31744a294584a36bf764a0ffa3255a8e69f036 ] When ident_pud_init() uses only GB pages to create identity maps, large ranges of addresses not actually requested can be included in the resulting table; a 4K request will map a full GB. This can include a lot of extra address space past that requested, including areas marked reserved by the BIOS. That allows processor speculation into reserved regions, that on UV systems can cause system halts. Only use GB pages when map creation requests include the full GB page of space. Fall back to using smaller 2M pages when only portions of a GB page are included in the request. No attempt is made to coalesce mapping requests. If a request requires a map entry at the 2M (pmd) level, subsequent mapping requests within the same 1G region will also be at the pmd level, even if adjacent or overlapping such requests could have been combined to map a full GB page. Existing usage starts with larger regions and then adds smaller regions, so this should not have any great consequence.

[PATCH v2] usb: roles: set switch registered flag early on

by Elson Roy Serrao

The role switch registration and set_role() can happen in parallel as they are invoked independent of each other. There is a possibility that a driver might spend significant amount of time in usb_role_switch_register() API due to the presence of time intensive operations like component_add() which operate under common mutex. This leads to a time window after allocating the switch and before setting the registered flag where the set role notifications are dropped. Below timeline summarizes this behavior Thread1 | Thread2 usb_role_switch_register() | | | ---> allocate switch | | | ---> component_add() | usb_role_switch_set_role() | | | | | --> Drop role notifications | | since sw->registered | | flag is not set. | | --->Set registered flag.| To avoid this, set the registered flag early on in the switch register API.

[PATCH] fuse: revert back to __readahead_folio() for readahead

by Joanne Koong

In 3eab9d7bc2f4 ("fuse: convert readahead to use folios"), the logic was converted to using the new folio readahead code, which drops the reference on the folio once it is locked, using an inferred reference on the folio. Previously we held a reference on the folio for the entire duration of the readpages call. This is fine, however for the case for splice pipe responses where we will remove the old folio and splice in the new folio (see fuse_try_move_page()), we assume that there is a reference held on the folio for ap->folios, which is no longer the case. To fix this, revert back to __readahead_folio() which allows us to hold the reference on the folio for the duration of readpages until either we drop the reference ourselves in fuse_readpages_end() or the reference is dropped after it's replaced in the page cache in the splice case. This will fix the UAF bug that was reported.

[PATCH v5] arm64: mm: Populate vmemmap/linear at the page level for hotplugged sections

by Zhenhua Huang

On the arm64 platform with 4K base page config, SECTION_SIZE_BITS is set to 27, making one section 128M. The related page struct which vmemmap points to is 2M then. Commit c1cc1552616d ("arm64: MMU initialisation") optimizes the vmemmap to populate at the PMD section level which was suitable initially since hot plug granule is always one section(128M). However, commit ba72b4c8cf60 ("mm/sparsemem: support sub-section hotplug") introduced a 2M(SUBSECTION_SIZE) hot plug granule, which disrupted the existing arm64 assumptions. Considering the vmemmap_free -> unmap_hotplug_pmd_range path, when pmd_sect() is true, the entire PMD section is cleared, even if there is other effective subsection. For example page_struct_map1 and page_strcut_map2 are part of a single PMD entry and they are hot-added sequentially. Then page_struct_map1 is removed, vmemmap_free() will clear the entire PMD entry freeing the struct page map for the whole section, even though page_struct_map2 is still active. Similar problem exists with linear mapping as well, for 16K base page(PMD size = 32M) or 64K base page(PMD = 512M), their block mappings exceed SUBSECTION_SIZE. Tearing down the entire PMD mapping too will leave other subsections unmapped in the linear mapping. To address the issue, we need to prevent PMD/PUD/CONT mappings for both linear and vmemmap for non-boot sections if corresponding size on the given base page exceeds SUBSECTION_SIZE(2MB now). Cc: stable(a)vger.kernel.org # v5.4+ Fixes: ba72b4c8cf60 ("mm/sparsemem: support sub-section hotplug") Signed-off-by: Zhenhua Huang <quic_zhenhuah(a)quicinc.com> --- Hi Catalin and Anshuman, I have addressed comments so far, please help review.

[PATCH v1 03/16] arm64: hugetlb: Fix flush_hugetlb_tlb_range() invalidation level

by Ryan Roberts

commit c910f2b65518 ("arm64/mm: Update tlb invalidation routines for FEAT_LPA2") changed the "invalidation level unknown" hint from 0 to TLBI_TTL_UNKNOWN (INT_MAX). But the fallback "unknown level" path in flush_hugetlb_tlb_range() was not updated. So as it stands, when trying to invalidate CONT_PMD_SIZE or CONT_PTE_SIZE hugetlb mappings, we will spuriously try to invalidate at level 0 on LPA2-enabled systems. Fix this so that the fallback passes TLBI_TTL_UNKNOWN, and while we are at it, explicitly use the correct stride and level for CONT_PMD_SIZE and CONT_PTE_SIZE, which should provide a minor optimization.

[PATCH net V2] net: stmmac: dwmac-loongson: Set correct {tx,rx}_fifo_size

by Huacai Chen

Now for dwmac-loongson {tx,rx}_fifo_size are uninitialised, which means zero. This means dwmac-loongson doesn't support changing MTU because in stmmac_change_mtu() it requires the fifo size be no less than MTU. Thus, set the correct tx_fifo_size and rx_fifo_size for it (16KB multiplied by queue counts). Here {tx,rx}_fifo_size is initialised with the initial value (also the maximum value) of {tx,rx}_queues_to_use. So it will keep as 16KB if we don't change the queue count, and will be larger than 16KB if we change (decrease) the queue count.

[PATCH] tls: Check return value of get_cipher_desc in fill_sg_out

by Wentao Liang

The function get_cipher_desc() may return NULL if the cipher type is invalid or unsupported. In fill_sg_out(), the return value is used without any checks, which could lead to a NULL pointer dereference. This patch adds a DEBUG_NET_WARN_ON_ONCE check to ensure that cipher_desc is valid and offloadable before proceeding. This prevents potential crashes and provides a clear warning in debug builds.

[PATCH 2/2] cifs: deal with the channel loading lag while picking channels

by nspmangalore＠gmail.com

From: Shyam Prasad N <sprasad(a)microsoft.com> Our current approach to select a channel for sending requests is this: 1. iterate all channels to find the min and max queue depth 2. if min and max are not the same, pick the channel with min depth 3. if min and max are same, round robin, as all channels are equally loaded The problem with this approach is that there's a lag between selecting a channel and sending the request (that increases the queue depth on the channel). While these numbers will eventually catch up, there could be a skew in the channel usage, depending on the application's I/O parallelism and the server's speed of handling requests. With sufficient parallelism, this lag can artificially increase the queue depth, thereby impacting the performance negatively. This change will change the step 1 above to start the iteration from the last selected channel. This is to reduce the skew in channel usage even in the presence of this lag.

[PATCH] rust: rbtree: fix overindented list item

by Miguel Ojeda

Starting with Rust 1.86.0 (to be released 2025-04-03), Clippy will have a new lint, `doc_overindented_list_items` [1], which catches cases of overindented list items. The lint has been added by Yutaro Ohno, based on feedback from the kernel [2] on a patch that fixed a similar case -- commit 0c5928deada1 ("rust: block: fix formatting in GenDisk doc"). Clippy reports a single case in the kernel, apart from the one already fixed in the commit above: error: doc list item overindented --> rust/kernel/rbtree.rs:1152:5 | 1152 | /// null, it is a pointer to the root of the [`RBTree`]. | ^^^^ help: try using ` ` (2 spaces) | = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#doc_overindented_… = note: `-D clippy::doc-overindented-list-items` implied by `-D warnings` = help: to override `-D warnings` add `#[allow(clippy::doc_overindented_list_items)]` Thus clean it up.

[PATCH] objtool/rust: add one more `noreturn` Rust function

by Miguel Ojeda

Starting with Rust 1.85.0 (currently in beta, to be released 2025-02-20), under some kernel configurations with `CONFIG_RUST_DEBUG_ASSERTIONS=y`, one may trigger a new `objtool` warning: rust/kernel.o: warning: objtool: _R...securityNtB2_11SecurityCtx8as_bytes() falls through to next function _R...core3ops4drop4Drop4drop() due to a call to the `noreturn` symbol: core::panicking::assert_failed::<usize, usize> Thus add it to the list so that `objtool` knows it is actually `noreturn`. Do so matching with `strstr` since it is a generic. See commit 56d680dd23c3 ("objtool/rust: list `noreturn` Rust functions") for more details.

[PATCH v4 2/5] arm64: errata: Assume that unknown CPUs _are_ vulnerable to Spectre BHB

by Douglas Anderson

The code for detecting CPUs that are vulnerable to Spectre BHB was based on a hardcoded list of CPU IDs that were known to be affected. Unfortunately, the list mostly only contained the IDs of standard ARM cores. The IDs for many cores that are minor variants of the standard ARM cores (like many Qualcomm Kyro CPUs) weren't listed. This led the code to assume that those variants were not affected. Flip the code on its head and instead assume that a core is vulnerable if it doesn't have CSV2_3 but is unrecognized as being safe. This involves creating a "Spectre BHB safe" list. As of right now, the only CPU IDs added to the "Spectre BHB safe" list are ARM Cortex A35, A53, A55, A510, and A520. This list was created by looking for cores that weren't listed in ARM's list [1] as per review feedback on v2 of this patch [2]. Additionally Brahma A53 is added as per mailing list feedback [3]. NOTE: this patch will not actually _mitigate_ anyone, it will simply cause them to report themselves as vulnerable. If any cores in the system are reported as vulnerable but not mitigated then the whole system will be reported as vulnerable though the system will attempt to mitigate with the information it has about the known cores.

[PATCH v2 01/10] drm/i915: Make sure all planes in use by the joiner have their crtc included

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Any active plane needs to have its crtc included in the atomic state. For planes enabled via uapi that is all handler in the core. But when we use a plane for joiner the uapi code things the plane is disabled and therefore doesn't have a crtc. So we need to pull those in by hand. We do it first thing in intel_joiner_add_affected_crtcs() so that any newly added crtc will subsequently pull in all of its joined crtcs as well. The symptoms from failing to do this are: - duct tape in the form of commit 1d5b09f8daf8 ("drm/i915: Fix NULL ptr deref by checking new_crtc_state") - the plane's hw state will get overwritten by the disabled uapi state if it can't find the uapi counterpart plane in the atomic state from where it should copy the correct state Cc: stable(a)vger.kernel.org Reviewed-by: Maarten Lankhorst <maarten.lankhorst(a)linux.intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala(a)linux.intel.com> --- drivers/gpu/drm/i915/display/intel_display.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/drivers/gpu/drm/i915/display/intel_display.c b/drivers/gpu/drm/i915/display/intel_display.c index 6c1e7441313e..22bf46be2ca9 100644 --- a/drivers/gpu/drm/i915/display/intel_display.c +++ b/drivers/gpu/drm/i915/display/intel_display.c @@ -6695,12 +6695,30 @@ static int intel_async_flip_check_hw(struct intel_atomic_state *state, struct in static int intel_joiner_add_affected_crtcs(struct intel_atomic_state *state) { struct drm_i915_private *i915 = to_i915(state->base.dev); + const struct intel_plane_state *plane_state; struct intel_crtc_state *crtc_state; + struct intel_plane *plane; struct intel_crtc *crtc; u8 affected_pipes = 0; u8 modeset_pipes = 0; int i; + /* + * Any plane which is in use by the joiner needs its crtc. + * Pull those in first as this will not have happened yet + * if the plane remains disabled according to uapi. + */ + for_each_new_intel_plane_in_state(state, plane, plane_state, i) { + crtc = to_intel_crtc(plane_state->hw.crtc); + if (!crtc) + continue; + + crtc_state = intel_atomic_get_crtc_state(&state->base, crtc); + if (IS_ERR(crtc_state)) + return PTR_ERR(crtc_state); + } + + /* Now pull in all joined crtcs */ for_each_new_intel_crtc_in_state(state, crtc, crtc_state, i) { affected_pipes |= crtc_state->joiner_pipes; if (intel_crtc_needs_modeset(crtc_state)) -- 2.45.3

[PATCH v2] soc: qcom: pdr: Fix the potential deadlock

by Mukesh Ojha

When some client process A call pdr_add_lookup() to add the look up for the service and does schedule locator work, later a process B got a new server packet indicating locator is up and call pdr_locator_new_server() which eventually sets pdr->locator_init_complete to true which process A sees and takes list lock and queries domain list but it will timeout due to deadlock as the response will queued to the same qmi->wq and it is ordered workqueue and process B is not able to complete new server request work due to deadlock on list lock. Process A Process B process_scheduled_works() pdr_add_lookup() qmi_data_ready_work() process_scheduled_works() pdr_locator_new_server() pdr->locator_init_complete=true; pdr_locator_work() mutex_lock(&pdr->list_lock); pdr_locate_service() mutex_lock(&pdr->list_lock); pdr_get_domain_list() pr_err("PDR: %s get domain list txn wait failed: %d\n", req->service_name, ret); Fix it by removing the unnecessary list iteration as the list iteration is already being done inside locator work, so avoid it here and just call schedule_work() here.

[PATCH v1 02/16] arm64: hugetlb: Fix huge_ptep_get_and_clear() for non-present ptes

by Ryan Roberts

arm64 supports multiple huge_pte sizes. Some of the sizes are covered by a single pte entry at a particular level (PMD_SIZE, PUD_SIZE), and some are covered by multiple ptes at a particular level (CONT_PTE_SIZE, CONT_PMD_SIZE). So the function has to figure out the size from the huge_pte pointer. This was previously done by walking the pgtable to determine the level, then using the PTE_CONT bit to determine the number of ptes. But the PTE_CONT bit is only valid when the pte is present. For non-present pte values (e.g. markers, migration entries), the previous implementation was therefore erroniously determining the size. There is at least one known caller in core-mm, move_huge_pte(), which may call huge_ptep_get_and_clear() for a non-present pte. So we must be robust to this case. Additionally the "regular" ptep_get_and_clear() is robust to being called for non-present ptes so it makes sense to follow the behaviour. Fix this by using the new sz parameter which is now provided to the function. Additionally when clearing each pte in a contig range, don't gather the access and dirty bits if the pte is not present. An alternative approach that would not require API changes would be to store the PTE_CONT bit in a spare bit in the swap entry pte. But it felt cleaner to follow other APIs' lead and just pass in the size. While we are at it, add some debug warnings in functions that require the pte is present. As an aside, PTE_CONT is bit 52, which corresponds to bit 40 in the swap entry offset field (layout of non-present pte). Since hugetlb is never swapped to disk, this field will only be populated for markers, which always set this bit to 0 and hwpoison swap entries, which set the offset field to a PFN; So it would only ever be 1 for a 52-bit PVA system where memory in that high half was poisoned (I think!). So in practice, this bit would almost always be zero for non-present ptes and we would only clear the first entry if it was actually a contiguous block. That's probably a less severe symptom than if it was always interpretted as 1 and cleared out potentially-present neighboring PTEs.

[PATCH] net: microchip: sparx5: Fix potential NULL pointer dereference in debugfs

by Wentao Liang

In vcap_debugfs_show_rule_keyset(), the function vcap_keyfields() returns a NULL pointer upon allocation failure. This can lead to a NULL pointer dereference in vcap_debugfs_show_rule_keyfield(). To prevent this, add a check for a NULL return value from vcap_keyfields() and continue the loop if it is NULL.

[PATCH] drm/amdgpu: Remove redundant return value checks for amdgpu_ras_error_data_init

by Wentao Liang

The function amdgpu_ras_error_data_init() always returns 0, making its return value checks redundant. This patch changes its return type to void and removes all unnecessary checks in the callers. This simplifies the code and avoids confusion about the function's behavior. Additionally, this change keeps the usage consistent with amdgpu_ras_do_page_retirement(), which also does not check the return value.

[PATCH v2] HID: corsair-void: Update power supply values with a unified work handler

patch "iio: filter: admv8818: Force initialization of SDO" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: filter: admv8818: Force initialization of SDO to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. From cc2c3540d9477a9931fb0fd851fcaeba524a5b35 Mon Sep 17 00:00:00 2001 From: Sam Winchenbach <swinchenbach(a)arka.org> Date: Mon, 3 Feb 2025 13:34:34 +0000 Subject: iio: filter: admv8818: Force initialization of SDO When a weak pull-up is present on the SDO line, regmap_update_bits fails to write both the SOFTRESET and SDOACTIVE bits because it incorrectly reads them as already set. Since the soft reset disables the SDO line, performing a read-modify-write operation on ADI_SPI_CONFIG_A to enable the SDO line doesn't make sense.

[PATCH net 0/2] rtnetlink: Fix small memory leaks

[PATCH] arm: pgtable: fix NULL pointer dereference issue

When update_mmu_cache_range() is called by update_mmu_cache(), the vmf parameter is NULL, which will cause a NULL pointer dereference issue in adjust_pte(): Unable to handle kernel NULL pointer dereference at virtual address 00000030 when read Hardware name: Atmel AT91SAM9 PC is at update_mmu_cache_range+0x1e0/0x278 LR is at pte_offset_map_rw_nolock+0x18/0x2c Call trace: update_mmu_cache_range from remove_migration_pte+0x29c/0x2ec remove_migration_pte from rmap_walk_file+0xcc/0x130 rmap_walk_file from remove_migration_ptes+0x90/0xa4 remove_migration_ptes from migrate_pages_batch+0x6d4/0x858 migrate_pages_batch from migrate_pages+0x188/0x488 migrate_pages from compact_zone+0x56c/0x954 compact_zone from compact_node+0x90/0xf0 compact_node from kcompactd+0x1d4/0x204 kcompactd from kthread+0x120/0x12c kthread from ret_from_fork+0x14/0x38 Exception stack(0xc0d8bfb0 to 0xc0d8bff8) To fix it, do not rely on whether 'ptl' is equal to decide whether to hold the pte lock, but decide it by whether CONFIG_SPLIT_PTE_PTLOCKS is enabled. In addition, if two vmas map to the same PTE page, there is no need to hold the pte lock again, otherwise a deadlock will occur. Just add the need_lock parameter to let adjust_pte() know this information.

[PATCH v4] wifi: mac80211: fix integer overflow in hwmp_route_info_get()

by Gavrilov Ilia

Since the new_metric and last_hop_metric variables can reach the MAX_METRIC(0xffffffff) value, an integer overflow may occur when multiplying them by 10/9. It can lead to incorrect behavior.

[PATCH] drm/i915: Check drm_syncobj_fence_get return value in eb_fences_add

by Wentao Liang

The function drm_syncobj_fence_get() may return NULL if the syncobj has no fence. In eb_fences_add(), this return value is not checked, leading to a potential NULL pointer dereference in i915_request_await_dma_fence(). This patch adds a check for the return value of drm_syncobj_fence_get and returns an error if it is NULL, preventing the NULL pointer dereference.

However, in doing so it also broke fetching the GuC log via debugfs since xe_print_blob_ascii85() simply bails out. The fix is to avoid the extra newlines: the devcoredump interface is line-oriented and adding random newlines in the middle breaks it. If a tool is able to parse it by looking at the data and checking for chars that are out of the ascii85 space, it can still do so. A format change that breaks the line-oriented output on devcoredump however needs better coordination with existing tools. v2: Add suffix description comment v3: Reword explanation of xe_print_blob_ascii85() calling drm_puts() in a loop Reviewed-by: José Roberto de Souza <jose.souza(a)intel.com> Cc: John Harrison <John.C.Harrison(a)Intel.com> Cc: Julia Filipchuk <julia.filipchuk(a)intel.com> Cc: José Roberto de Souza <jose.souza(a)intel.com> Cc: stable(a)vger.kernel.org Fixes: 70fb86a85dc9 ("drm/xe: Revert some changes that break a mesa debug tool") Fixes: ec1455ce7e35 ("drm/xe/devcoredump: Add ASCII85 dump helper function") Link: https://patchwork.freedesktop.org/patch/msgid/20250123202307.95103-2-jose.s… Signed-off-by: Lucas De Marchi <lucas.demarchi(a)intel.com> (cherry picked from commit 2c95bbf5002776117a69caed3b31c10bf7341bec) Signed-off-by: Rodrigo Vivi <rodrigo.vivi(a)intel.com> diff --git a/drivers/gpu/drm/xe/xe_devcoredump.c b/drivers/gpu/drm/xe/xe_devcoredump.c index a7946a76777e..39fe485d2085 100644 --- a/drivers/gpu/drm/xe/xe_devcoredump.c +++ b/drivers/gpu/drm/xe/xe_devcoredump.c @@ -391,42 +391,34 @@ int xe_devcoredump_init(struct xe_device *xe) /** * xe_print_blob_ascii85 - print a BLOB to some useful location in ASCII85 * - * The output is split to multiple lines because some print targets, e.g. dmesg - * cannot handle arbitrarily long lines.

[PATCH 5.4/5.10 0/2] vlan: fix netdev refcount leak

by Ivan Delalande

We started hitting the same netdevice refcount leak that had been reported and fixed in mainline, and that Olivier had backported into v5.15.142. So this is the same series further backported to the latest v5.10 which fixes the issues we were seeing there. This version also applies without change on v5.4 which should also be affected, but it was only build-tested there as we don't have an easy way to run our tests on that version.

[PATCH v2] usb: gadget: core: flush gadget workqueue after device removal

by Roy Luo

device_del() can lead to new work being scheduled in gadget->work workqueue. This is observed, for example, with the dwc3 driver with the following call stack: device_del() gadget_unbind_driver() usb_gadget_disconnect_locked() dwc3_gadget_pullup() dwc3_gadget_soft_disconnect() usb_gadget_set_state() schedule_work(&gadget->work) Move flush_work() after device_del() to ensure the workqueue is cleaned up.

[PATCH 1/3] maple_tree: may miss to set node dead on destroy

by Wei Yang

On destroy, we should set each node dead. But current code miss this when the maple tree has only the root node. The reason is mt_destroy_walk() leverage mte_destroy_descend() to set node dead, but this is skipped since the only root node is a leaf. This patch fixes this by setting the root dead before mt_destroy_walk(). Fixes: 54a611b60590 ("Maple Tree: add new data structure") Signed-off-by: Wei Yang <richard.weiyang(a)gmail.com> CC: Liam R.

[PATCH V3 1/2] x86/tdx: Route safe halt execution via tdx_safe_halt()

by Vishal Annapurve

Direct HLT instruction execution causes #VEs for TDX VMs which is routed to hypervisor via TDCALL. safe_halt() routines execute HLT in STI-shadow so IRQs need to remain disabled until the TDCALL to ensure that pending IRQs are correctly treated as wake events. So "sti;hlt" sequence needs to be replaced with "TDCALL; raw_local_irq_enable()" for TDX VMs. Commit bfe6ed0c6727 ("x86/tdx: Add HLT support for TDX guests") prevented the idle routines from using "sti;hlt". But it missed the paravirt routine which can be reached like this as an example: acpi_safe_halt() => raw_safe_halt() => arch_safe_halt() => irq.safe_halt() => pv_native_safe_halt() Modify tdx_safe_halt() to implement the sequence "TDCALL; raw_local_irq_enable()" and invoke tdx_halt() from idle routine which just executes TDCALL without changing state of interrupts. If CONFIG_PARAVIRT_XXL is disabled, "sti;hlt" sequences can still get executed from TDX VMs via paths like: acpi_safe_halt() => raw_safe_halt() => arch_safe_halt() => native_safe_halt() There is a long term plan to fix these paths by carving out irq.safe_halt() outside paravirt framework.

[PATCH V4 1/4] x86/paravirt: Move halt paravirt calls under CONFIG_PARAVIRT

by Vishal Annapurve

From: "Kirill A. Shutemov" <kirill.shutemov(a)linux.intel.com> CONFIG_PARAVIRT_XXL is mainly defined/used by XEN PV guests. For other VM guest types, features supported under CONFIG_PARAVIRT are self sufficient. CONFIG_PARAVIRT mainly provides support for TLB flush operations and time related operations. For TDX guest as well, paravirt calls under CONFIG_PARVIRT meets most of its requirement except the need of HLT and SAFE_HLT paravirt calls, which is currently defined under CONFIG_PARAVIRT_XXL. Since enabling CONFIG_PARAVIRT_XXL is too bloated for TDX guest like platforms, move HLT and SAFE_HLT paravirt calls under CONFIG_PARAVIRT. Moving HLT and SAFE_HLT paravirt calls are not fatal and should not break any functionality for current users of CONFIG_PARAVIRT.

[ 3359.353842] BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48 [ 3359.353848] in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 140605, name: kunit_try_catch [ 3359.353853] preempt_count: 1, expected: 0 : [ 3359.353933] Call trace: : [ 3359.353955] rt_spin_lock+0x70/0x140 [ 3359.353959] find_vmap_area+0x84/0x168 [ 3359.353963] find_vm_area+0x1c/0x50 [ 3359.353966] print_address_description.constprop.0+0x2a0/0x320 [ 3359.353972] print_report+0x108/0x1f8 [ 3359.353976] kasan_report+0x90/0xc8 [ 3359.353980] __asan_load1+0x60/0x70 print_address_description() is run with a raw_spinlock_t acquired and interrupt disabled. find_vm_area() needs to acquire a spinlock_t which becomes a sleeping lock in the RT kernel. IOW, we can't call find_vm_area() in a RT kernel. Fix this bug report by skipping the find_vm_area() call in this case and just print out the address as is. For !RT kernel, follow the example set in commit 0cce06ba859a ("debugobjects,locking: Annotate debug_object_fill_pool() wait type violation") and use DEFINE_WAIT_OVERRIDE_MAP() to avoid a spinlock_t inside raw_spinlock_t warning.

[PATCH net 6/6] igc: Set buffer type for empty frames in igc_init_empty_frame

by Tony Nguyen

From: Song Yoong Siang <yoong.siang.song(a)intel.com> Set the buffer type to IGC_TX_BUFFER_TYPE_SKB for empty frame in the igc_init_empty_frame function.

[PATCH 0/7] PCI: apple: support t6020

[PATCH v2 0/8] KVM: arm64: FPSIMD/SVE/SME fixes

by Mark Rutland

These patches fix some issues with the way KVM manages FPSIMD/SVE/SME state. The series supersedes my earlier attempt at fixing the host SVE state corruption issue: https://lore.kernel.org/linux-arm-kernel/20250121100026.3974971-1-mark.rutl… Patch 1 addresses the host SVE state corruption issue by always saving and unbinding the host state when loading a vCPU, as discussed on the earlier patch: https://lore.kernel.org/linux-arm-kernel/Z4--YuG5SWrP_pW7@J2N7QTR9R3/ https://lore.kernel.org/linux-arm-kernel/86plkful48.wl-maz@kernel.org/ Patches 2 to 4 remove code made redundant by patch 1. These probably warrant backporting along with patch 1 as there is some historical brokenness in the code they remove. Patches 5 to 7 are preparatory refactoring for patch 8, and are not intended to have any functional impact. Patch 8 addresses some mismanagement of ZCR_EL{1,2} which can result in the host VMM unexpectedly receiving a SIGKILL. To fix this, we eagerly switch ZCR_EL{1,2} at guest<->host transitions, as discussed on another series: https://lore.kernel.org/linux-arm-kernel/Z4pAMaEYvdLpmbg2@J2N7QTR9R3/ https://lore.kernel.org/linux-arm-kernel/86o6zzukwr.wl-maz@kernel.org/ https://lore.kernel.org/linux-arm-kernel/Z5Dc-WMu2azhTuMn@J2N7QTR9R3/ The end result is that KVM loses ~100 lines of code, and becomes a bit simpler to reason about. I've pushed these patches to the arm64-kvm-fpsimd-fixes-20250206 tag on my kernel.org repo: https://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git/ git://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git The (unstable) arm64/kvm/fpsimd-fixes branch in that repo contains the fixes plus additional debug patches I've used for testing. I've given this some basic testing on a virtual platform, booting a host and a guest with and without constraining the guest's max SVE VL, with: * kvm_arm.mode=vhe * kvm_arm.mode=nvhe * kvm_arm.mode=protected (IIUC this will default to hVHE) Since v1 [1]: * Address some additional compiler warnings in patch 7 * Use ZCR_EL1 alias in VHE code * Fold in Tested-by and Reviewed-by tags * Fix typos [1] https://lore.kernel.org/linux-arm-kernel/20250204152100.705610-1-mark.rutla… Mark.

[PATCH v3 0/3] alpha: stack fixes

by Ivan Kokshaysky

This series fixes oopses on Alpha/SMP observed since kernel v6.9. [1] Thanks to Magnus Lindholm for identifying that remarkably longstanding bug. The problem is that GCC expects 16-byte alignment of the incoming stack since early 2004, as Maciej found out [2]: Having actually dug speculatively I can see that the psABI was changed in GCC 3.5 with commit e5e10fb4a350 ("re PR target/14539 (128-bit long double improperly aligned)") back in Mar 2004, when the stack pointer alignment was increased from 8 bytes to 16 bytes, and arch/alpha/kernel/entry.S has various suspicious stack pointer adjustments, starting with SP_OFF which is not a whole multiple of 16. Also, as Magnus noted, "ALPHA Calling Standard" [3] required the same: D.3.1 Stack Alignment This standard requires that stacks be octaword aligned at the time a new procedure is invoked. However: - the "normal" kernel stack is always misaligned by 8 bytes, thanks to the odd number of 64-bit words in 'struct pt_regs', which is the very first thing pushed onto the kernel thread stack; - syscall, fault, interrupt etc. handlers may, or may not, receive aligned stack depending on numerous factors. Somehow we got away with it until recently, when we ended up with a stack corruption in kernel/smp.c:smp_call_function_single() due to its use of 32-byte aligned local data and the compiler doing clever things allocating it on the stack. Patche 1 is preparatory; 2 - the main fix; 3 - fixes remaining special cases. Ivan.

[PATCH] cifs: pick channels for individual subrequests

by nspmangalore＠gmail.com

From: Shyam Prasad N <sprasad(a)microsoft.com> The netfs library could break down a read request into multiple subrequests. When multichannel is used, there is potential to improve performance when each of these subrequests pick a different channel. Today we call cifs_pick_channel when the main read request is initialized in cifs_init_request. This change moves this to cifs_prepare_read, which is the right place to pick channel since it gets called for each subrequest. Interestingly cifs_prepare_write already does channel selection for individual subreq, but looks like it was missed for read. This is especially important when multichannel is used with increased rasize. In my test setup, with rasize set to 8MB, a sequential read of large file was taking 11.5s without this change. With the change, it completed in 9s. The difference is even more signigicant with bigger rasize.

[PATCH 2/3] perf/x86/intel: Fix ARCH_PERFMON_NUM_COUNTER_LEAF

by kan.liang＠linux.intel.com

From: Kan Liang <kan.liang(a)linux.intel.com> The EAX of the CPUID Leaf 023H enumerates the mask of valid sub-leaves. To tell the availability of the sub-leaf 1 (enumerate the counter mask), perf should check the bit 1 (0x2) of EAS, rather than bit 0 (0x1). The error is not user-visible on bare metal. Because the sub-leaf 0 and the sub-leaf 1 are always available. However, it may bring issues in a virtualization environment when a VMM only enumerates the sub-leaf 0. Introduce the cpuid35_e?x to replace the macros, which makes the implementation style consistent.

Because the kernel preserves the original DEBUGCTL, even when toggling LBRs, leaving DEBUGCTL.LBR as is results in running with LBRs enabled at all times.

[PATCH] Revert "drm/amd/display: Fix green screen issue after suspend"

by Alex Deucher

From: Rodrigo Siqueira <Rodrigo.Siqueira(a)amd.com> This reverts commit 87b7ebc2e16c14d32a912f18206a4d6cc9abc3e8. A long time ago, we had an issue with the Raven system when it was connected to two displays: one with DP and another with HDMI. After the system woke up from suspension, we saw a solid green screen caused by an underflow generated by bad DCC metadata. To workaround this issue, the 'commit 87b7ebc2e16c ("drm/amd/display: Fix green screen issue after suspend")' was introduced to disable the DCC for a few frames after in the resume phase. However, in hindsight, this solution was probably a workaround at the kernel level for some issues from another part (probably other driver components or user space). After applying this patch and trying to reproduce the green issue in a similar hardware system but using the latest kernel and userspace, we cannot see the issue, which makes this workaround obsolete and creates extra unnecessary complexity to the code; for all of this reason, this commit reverts the original change.

[PATCH v2] arm64: dts: mediatek: mt8188: Assign apll1 clock as parent to avoid hang

by Nícolas F. R. A. Prado

Certain registers in the AFE IO space require the apll1 clock to be enabled in order to be read, otherwise the machine hangs (registers like 0x280, 0x410 (AFE_GAIN1_CON0) and 0x830 (AFE_CONN0_5)). During AFE driver probe, when initializing the regmap for the AFE IO space those registers are read, resulting in a hang during boot. This has been observed on the Genio 700 EVK, Genio 510 EVK and MT8188-Geralt-Ciri Chromebook, all of which are based on the MT8188 SoC. Assign CLK_TOP_APLL1_D4 as the parent for CLK_TOP_A1SYS_HP, which is enabled during register read and write, to make sure the apll1 is enabled during register operations and prevent the MT8188 machines from hanging during boot.

[PATCH 1/2] drm/i915/gvt: Store ->kvm reference in intel_vgpu struct.

by Andrey Ryabinin

'vfio_device' keeps the ->kvm pointer with elevated counter from the first open of the device up until the last close(). So the kvm struct and its dependencies (kvm kthreads, cgroups ...) kept alive even for VFIO device that don't need ->kvm. Copy ->kvm pointer from the vfio_device struct and store it in the 'intel_vgpu'. Note that kvm_page_track_[un]register_notifier() already does get/put calls, keeping the kvm struct alive. This will allow to release ->kvm from the vfio_device righ after the first open call, so that devices not using kvm not keeping it alive. Devices that are using kvm (like intel_vgpu) will be expected to mange the lifetime of the kvm struct by themselves.

[PATCH v3] sched/topology: Enable topology_span_sane check only for debug builds

by Naman Jain

From: Saurabh Sengar <ssengar(a)linux.microsoft.com> On a x86 system under test with 1780 CPUs, topology_span_sane() takes around 8 seconds cumulatively for all the iterations. It is an expensive operation which does the sanity of non-NUMA topology masks. CPU topology is not something which changes very frequently hence make this check optional for the systems where the topology is trusted and need faster bootup. Restrict this to sched_verbose kernel cmdline option so that this penalty can be avoided for the systems who want to avoid it.

[PATCH v3 0/8] KVM: arm64: FPSIMD/SVE/SME fixes

by Mark Rutland

These patches fix some issues with the way KVM manages FPSIMD/SVE/SME state. The series supersedes my earlier attempt at fixing the host SVE state corruption issue: https://lore.kernel.org/linux-arm-kernel/20250121100026.3974971-1-mark.rutl… Patch 1 addresses the host SVE state corruption issue by always saving and unbinding the host state when loading a vCPU, as discussed on the earlier patch: https://lore.kernel.org/linux-arm-kernel/Z4--YuG5SWrP_pW7@J2N7QTR9R3/ https://lore.kernel.org/linux-arm-kernel/86plkful48.wl-maz@kernel.org/ Patches 2 to 4 remove code made redundant by patch 1. These probably warrant backporting along with patch 1 as there is some historical brokenness in the code they remove. Patches 5 to 7 are preparatory refactoring for patch 8, and are not intended to have any functional impact. Patch 8 addresses some mismanagement of ZCR_EL{1,2} which can result in the host VMM unexpectedly receiving a SIGKILL. To fix this, we eagerly switch ZCR_EL{1,2} at guest<->host transitions, as discussed on another series: https://lore.kernel.org/linux-arm-kernel/Z4pAMaEYvdLpmbg2@J2N7QTR9R3/ https://lore.kernel.org/linux-arm-kernel/86o6zzukwr.wl-maz@kernel.org/ https://lore.kernel.org/linux-arm-kernel/Z5Dc-WMu2azhTuMn@J2N7QTR9R3/ The end result is that KVM loses ~100 lines of code, and becomes a bit simpler to reason about. I've pushed these patches to the arm64-kvm-fpsimd-fixes-20250210 tag on my kernel.org repo: https://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git/ git://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git The (unstable) arm64/kvm/fpsimd-fixes branch in that repo contains the fixes plus additional debug patches I've used for testing. I've given this some basic testing on a virtual platform, booting a host and a guest with and without constraining the guest's max SVE VL, with: * kvm_arm.mode=vhe * kvm_arm.mode=nvhe * kvm_arm.mode=protected (IIUC this will default to hVHE) Since v1 [1]: * Address some additional compiler warnings in patch 7 * Use ZCR_EL1 alias in VHE code * Fold in Tested-by and Reviewed-by tags * Fix typos Since v2 [2]: * Ensure context synchronization in patch 8 * Fold in Tested-by and Reviewed-by tags * Fix typos [1] https://lore.kernel.org/linux-arm-kernel/20250204152100.705610-1-mark.rutla… [2] https://lore.kernel.org/linux-arm-kernel/20250206141102.954688-1-mark.rutla… Mark.

Each commit message is retained for reference. 1) Allow a GGTT mapped batch to be submitted to user exec queue For a OA use case, one of the HW registers needs to be modified by submitting an MI_LOAD_REGISTER_IMM command to the users exec queue, so that the register is modified in the user's hardware context. In order to do this a batch that is mapped in GGTT, needs to be submitted to the user exec queue. Since all user submissions use q->vm and hence PPGTT, add some plumbing to enable submission of batches mapped in GGTT. v2: ggtt is zero-initialized, so no need to set it false (Matt Brost) 2) xe/oa: Use MI_LOAD_REGISTER_IMMEDIATE to enable OAR/OAC To enable OAR/OAC, a bit in RING_CONTEXT_CONTROL needs to be set. Setting this bit cause the context image size to change and if not done correct, can cause undesired hangs. Current code uses a separate exec_queue to modify this bit and is error-prone. As per HW recommendation, submit MI_LOAD_REGISTER_IMM to the target hardware context to modify the relevant bit. In v2 version, an attempt to submit everything to the user-queue was made, but it failed the unprivileged-single-ctx-counters test. It appears that the OACTXCONTROL must be modified from a remote context. In v3 version, all context specific register configurations were moved to use LOAD_REGISTER_IMMEDIATE and that seems to work well. This is a cleaner way, since we can now submit all configuration to user exec_queue and the fence handling is simplified. v2: (Matt) - set job->ggtt to true if create job is successful - unlock vm on job error (Ashutosh) - don't wait on job submission - use kernel exec queue where possible v3: (Ashutosh) - Fix checkpatch issues - Remove extra spaces/new-lines - Add Fixes: and Cc: tags - Reset context control bit when OA stream is closed - Submit all config via MI_LOAD_REGISTER_IMMEDIATE (Umesh) - Update commit message for v3 experiment - Squash patches for easier port to stable v4: (Ashutosh) - No need to pass q to xe_oa_submit_bb - Do not support exec queues with width > 1 - Fix disabling of CTX_CTRL_OAC_CONTEXT_ENABLE v5: (Ashutosh) - Drop reg_lri related comments - Use XE_OA_SUBMIT_NO_DEPS in xe_oa_load_with_lri Fixes: 8135f1c09dd2 ("drm/xe/oa: Don't reset OAC_CONTEXT_ENABLE on OA stream close") Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa(a)intel.com> Reviewed-by: Matthew Brost <matthew.brost(a)intel.com> # commit 1 Reviewed-by: Ashutosh Dixit <ashutosh.dixit(a)intel.com> Cc: stable(a)vger.kernel.org Reviewed-by: Jonathan Cavitt <jonathan.cavitt(a)intel.com> Signed-off-by: Ashutosh Dixit <ashutosh.dixit(a)intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241220171919.571528-2-umesh… diff --git a/drivers/gpu/drm/xe/xe_oa.c b/drivers/gpu/drm/xe/xe_oa.c index ae94490b0eac..9add60097ab5 100644 --- a/drivers/gpu/drm/xe/xe_oa.c +++ b/drivers/gpu/drm/xe/xe_oa.c @@ -74,12 +74,6 @@ struct xe_oa_config { struct rcu_head rcu;

Microchip documentation and even sample code from Atmel emphasises the need for a memory barrier before the first MMIO transaction to the AHB-connected QSPI, and before the last write to its registers via APB. This is achieved by the following lines in `atmel_qspi_transfer()`: /* Dummy read of QSPI_IFR to synchronize APB and AHB accesses */ (void)atmel_qspi_read(aq, QSPI_IFR); However, the current documentation makes no mention to synchronization requirements in the other direction, i.e. after the last data written via AHB, and before the first register access on APB. In our case, we were facing an issue where the QSPI peripheral would cease to send any new CSR (nCS Rise) interrupts, leading to a timeout in `atmel_qspi_wait_for_completion()` and ultimately this panic in higher levels: ubi0 error: ubi_io_write: error -110 while writing 63108 bytes to PEB 491:128, written 63104 bytes After months of extensive research of the codebase, fiddling around the debugger with kgdb, and back-and-forth with Microchip, we came to the conclusion that the issue is probably that the peripheral is still busy receiving on AHB when the LASTXFER bit is written to its Control Register on APB, therefore this write gets lost, and the peripheral still thinks there is more data to come in the MMIO transfer. This was first formulated when we noticed that doubling the write() of QSPI_CR_LASTXFER seemed to solve the problem. Ultimately, the solution is to introduce memory barriers after the AHB-mapped MMIO transfers, to ensure ordering.

Each commit message is retained for reference. 1) Allow a GGTT mapped batch to be submitted to user exec queue For a OA use case, one of the HW registers needs to be modified by submitting an MI_LOAD_REGISTER_IMM command to the users exec queue, so that the register is modified in the user's hardware context. In order to do this a batch that is mapped in GGTT, needs to be submitted to the user exec queue. Since all user submissions use q->vm and hence PPGTT, add some plumbing to enable submission of batches mapped in GGTT. v2: ggtt is zero-initialized, so no need to set it false (Matt Brost) 2) xe/oa: Use MI_LOAD_REGISTER_IMMEDIATE to enable OAR/OAC To enable OAR/OAC, a bit in RING_CONTEXT_CONTROL needs to be set. Setting this bit cause the context image size to change and if not done correct, can cause undesired hangs. Current code uses a separate exec_queue to modify this bit and is error-prone. As per HW recommendation, submit MI_LOAD_REGISTER_IMM to the target hardware context to modify the relevant bit. In v2 version, an attempt to submit everything to the user-queue was made, but it failed the unprivileged-single-ctx-counters test. It appears that the OACTXCONTROL must be modified from a remote context. In v3 version, all context specific register configurations were moved to use LOAD_REGISTER_IMMEDIATE and that seems to work well. This is a cleaner way, since we can now submit all configuration to user exec_queue and the fence handling is simplified. v2: (Matt) - set job->ggtt to true if create job is successful - unlock vm on job error (Ashutosh) - don't wait on job submission - use kernel exec queue where possible v3: (Ashutosh) - Fix checkpatch issues - Remove extra spaces/new-lines - Add Fixes: and Cc: tags - Reset context control bit when OA stream is closed - Submit all config via MI_LOAD_REGISTER_IMMEDIATE (Umesh) - Update commit message for v3 experiment - Squash patches for easier port to stable v4: (Ashutosh) - No need to pass q to xe_oa_submit_bb - Do not support exec queues with width > 1 - Fix disabling of CTX_CTRL_OAC_CONTEXT_ENABLE v5: (Ashutosh) - Drop reg_lri related comments - Use XE_OA_SUBMIT_NO_DEPS in xe_oa_load_with_lri Fixes: 8135f1c09dd2 ("drm/xe/oa: Don't reset OAC_CONTEXT_ENABLE on OA stream close") Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa(a)intel.com> Reviewed-by: Matthew Brost <matthew.brost(a)intel.com> # commit 1 Reviewed-by: Ashutosh Dixit <ashutosh.dixit(a)intel.com> Cc: stable(a)vger.kernel.org Reviewed-by: Jonathan Cavitt <jonathan.cavitt(a)intel.com> Signed-off-by: Ashutosh Dixit <ashutosh.dixit(a)intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241220171919.571528-2-umesh… diff --git a/drivers/gpu/drm/xe/xe_oa.c b/drivers/gpu/drm/xe/xe_oa.c index ae94490b0eac..9add60097ab5 100644 --- a/drivers/gpu/drm/xe/xe_oa.c +++ b/drivers/gpu/drm/xe/xe_oa.c @@ -74,12 +74,6 @@ struct xe_oa_config { struct rcu_head rcu;

[PATCH 1/5] ovl: don't allow datadir only

by Miklos Szeredi

In theory overlayfs could support upper layer directly referring to a data layer, but there's no current use case for this. Originally, when data-only layers were introduced, this wasn't allowed, only introduced by the "datadir+" feture, but without actually handling this case, resuting in an Oops. Fix by disallowing datadir without lowerdir.

During the __mlx5_ib_dereg_mr() flow, the following sequence of calls occurs: mlx5_revoke_mr() mlx5r_umr_revoke_mr() mlx5r_umr_post_send_wait() At this point, the lkey is freed from the hardware's perspective. However, concurrently, mlx5_ib_invalidate_range() might be triggered by another task attempting to invalidate a range for the same freed lkey. This task will: - Acquire the umem_odp->umem_mutex lock. - Call mlx5r_umr_update_xlt() on the UMR QP. - Since the lkey has already been freed, this can lead to a CQE error, causing the UMR QP to enter an error state [1]. To resolve this race condition, the umem_odp->umem_mutex lock is now also acquired as part of the mlx5_revoke_mr() scope. Upon successful revoke, we set umem_odp->private which points to that MR to NULL, preventing any further invalidation attempts on its lkey.
