[PATCH 0/1] mm: Fix regression after THP PTE optimization on Xen PV Dom0

by Petr Vaněk

Hi all, I have found a problem in recent kernels 6.9+ when running under the Xen hypervisor as a PV dom0. In my setup (PV Dom0 with 4G RAM, using XFS), I shrink memory to 256M via the balloon driver after boot: xl mem-set Domain-0 256m Once memory is reduced, even running a simple command like ls usually triggers the following warning: [ 27.963562] [ T2553] page: refcount:88 mapcount:21 mapping:ffff88813ff6f6a8 index:0x110 pfn:0x10085c [ 27.963564] [ T2553] head: order:2 mapcount:83 entire_mapcount:0 nr_pages_mapped:4 pincount:0 [ 27.963565] [ T2553] memcg:ffff888003573000 [ 27.963567] [ T2553] aops:0xffffffff8226fd20 ino:82467c dentry name(?):"libc.so.6" [ 27.963570] [ T2553] flags: 0x2000000000416c(referenced|uptodate|lru|active|private|head|node=0|zone=2) [ 27.963573] [ T2553] raw: 002000000000416c ffffea0004021e88 ffffea0004021908 ffff88813ff6f6a8 [ 27.963574] [ T2553] raw: 0000000000000110 ffff88811bf06b60 0000005800000014 ffff888003573000 [ 27.963576] [ T2553] head: 002000000000416c ffffea0004021e88 ffffea0004021908 ffff88813ff6f6a8 [ 27.963577] [ T2553] head: 0000000000000110 ffff88811bf06b60 0000005800000014 ffff888003573000 [ 27.963578] [ T2553] head: 0020000000000202 ffffea0004021701 0000000400000052 00000000ffffffff [ 27.963580] [ T2553] head: 0000000300000003 8000000300000002 0000000000000014 0000000000000004 [ 27.963581] [ T2553] page dumped because: VM_WARN_ON_FOLIO((_Generic((page + nr_pages - 1), const struct page *: (const struct folio *)_compound_head(page + nr_pages - 1), struct page *: (struct folio *)_compound_head(page + nr_pages - 1))) != folio) [ 27.963590] [ T2553] ------------[ cut here ]------------ [ 27.963591] [ T2553] WARNING: CPU: 1 PID: 2553 at include/linux/rmap.h:427 __folio_rmap_sanity_checks+0x1a0/0x270 [ 27.963596] [ T2553] CPU: 1 UID: 0 PID: 2553 Comm: ls Not tainted 6.15.0-rc4-00002-ge0363f942651 #270 PREEMPT(undef) [ 27.963599] [ T2553] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-20240910_120124-localhost 04/01/2014 [ 27.963601] [ T2553] RIP: e030:__folio_rmap_sanity_checks+0x1a0/0x270 [ 27.963603] [ T2553] Code: 89 df e8 b3 7d fd ff 0f 0b e9 eb fe ff ff 48 8d 42 ff 48 39 c3 0f 84 0e ff ff ff 48 c7 c6 e8 49 5b 82 48 89 df e8 90 7d fd ff <0f> 0b e9 f8 fe ff ff 41 f7 c4 ff 0f 00 00 0f 85 b2 fe ff ff 49 8b [ 27.963605] [ T2553] RSP: e02b:ffffc90040f8fac0 EFLAGS: 00010246 [ 27.963608] [ T2553] RAX: 00000000000000e5 RBX: ffffea0004021700 RCX: 0000000000000000 [ 27.963609] [ T2553] RDX: 0000000000000000 RSI: 0000000000000001 RDI: 00000000ffffffff [ 27.963610] [ T2553] RBP: ffffc90040f8fae0 R08: 00000000ffffdfff R09: ffffffff82929308 [ 27.963612] [ T2553] R10: ffffffff82879360 R11: 0000000000000002 R12: ffffea0004021700 [ 27.963613] [ T2553] R13: 0000000000000005 R14: 0000000000000000 R15: 0000000000000005 [ 27.963625] [ T2553] FS: 00007ff06dafe740(0000) GS:ffff8880b7ccb000(0000) knlGS:0000000000000000 [ 27.963627] [ T2553] CS: e030 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 27.963628] [ T2553] CR2: 000055deb932f630 CR3: 0000000002844000 CR4: 0000000000050660 [ 27.963630] [ T2553] Call Trace: [ 27.963632] [ T2553] <TASK> [ 27.963633] [ T2553] folio_remove_rmap_ptes+0x24/0x2b0 [ 27.963635] [ T2553] unmap_page_range+0x132e/0x17e0 [ 27.963638] [ T2553] unmap_single_vma+0x81/0xd0 [ 27.963640] [ T2553] unmap_vmas+0xb5/0x180 [ 27.963642] [ T2553] exit_mmap+0x10c/0x460 [ 27.963644] [ T2553] mmput+0x59/0x120 [ 27.963647] [ T2553] do_exit+0x2d1/0xbd0 [ 27.963649] [ T2553] do_group_exit+0x2f/0x90 [ 27.963651] [ T2553] __x64_sys_exit_group+0x13/0x20 [ 27.963652] [ T2553] x64_sys_call+0x126b/0x1d70 [ 27.963655] [ T2553] do_syscall_64+0x54/0x120 [ 27.963657] [ T2553] entry_SYSCALL_64_after_hwframe+0x76/0x7e [ 27.963659] [ T2553] RIP: 0033:0x7ff06dbdbe9d [ 27.963660] [ T2553] Code: Unable to access opcode bytes at 0x7ff06dbdbe73.

I was able to bisect this issue to the commit: 10ebac4f95e7 ("mm/memory: optimize unmap/zap with PTE-mapped THP"). If I understand correctly, the folio from the first warning has 4 pages, but folio_pte_batch incorrectly counts 5 pages, because expected_pte and pte are both zero-valued PTEs, and the loop is not broken in such a case because pte_same() returns true.

The patch in the following message fixes the problem for me. It adds a check that breaks the loop when encountering non-present PTE, before the !pte_same() check. I still don't fully understand how the zero-valued PTE appears there or why this issue is triggered only when xen-balloon driver shrinks the memory. I wasn't able to reproduce it without shrinking.

[PATCH 0/3 V3] usb: usbtmc: Fix erroneous ioctl returns

by Dave Penkler

Recent tests with timeouts > INT_MAX produced random error returns with usbtmc_get_stb. This was caused by assigning the return value of wait_event_interruptible_timeout to an int which overflowed to negative values. Also return value on success was the remaining number of jiffies instead of 0. These patches fix all the cases where the return of wait_event_interruptible_timeout was assigned to an int and the case of the remaining jiffies return in usbtmc_get_stb. Patch 1: Fixes usbtmc_get_stb Patch 2: Fixes usbtmc488_ioctl_wait_srq Patch 3: Fixes usbtmc_generic_read Dave Penkler (3): usb: usbtmc: Fix erroneous get_stb ioctl error returns usb: usbtmc: Fix erroneous wait_srq ioctl return usb: usbtmc: Fix erroneous generic_read ioctl return drivers/usb/class/usbtmc.c | 53 ++++++++++++++++++++++---------------- 1 file changed, 31 insertions(+), 22 deletions(-) -- Changes V1 => V2 Add cc to stable line V2 => V3 Add susbsystem to cover letter 2.49.0

Please backport 980a573621ea to 6.12, 6.14

by Dionna Amalie Glaze

980a573621ea ("tpm: Make chip->{status,cancel,req_canceled} opt") This is a dependent commit for the series of patches to add the AMD SEV-SNP SVSM vTPM device driver. Kernel 6.11 added SVSM support, but not support for the critical component for boot integrity that follows the SEV-SNP threat model. That series https://lore.kernel.org/all/20250410135118.133240-1-sgarzare@redhat.com/ is applied at tip but is not yet in the mainline. I have confirmed that this patch applies cleanly. Stefano's patch series needs a minor tweak to the first patch due to the changed surrounding function declarations in arch/x86/include/asm/sev.h https://github.com/deeglaze/amdese-linux/commits/vtpm612/ I've independently tested the patches. -- -Dionna Glaze, PhD, CISSP, CCSP (she/her)

When the guest accesses a DR and host userspace isn't debugging the guest, KVM disables DR interception and loads the guest's values into hardware on VM-Enter and saves them on VM-Exit. This allows the guest to access DRs at will, e.g. so that a sequence of DR accesses to configure a breakpoint only generates one VM-Exit. For DR0-DR3, the logic/behavior is identical between VMX and SVM, and also identical between KVM_DEBUGREG_BP_ENABLED (userspace debugging the guest) and KVM_DEBUGREG_WONT_EXIT (guest using DRs), and so KVM handles loading DR0-DR3 in common code, _outside_ of the core kvm_x86_ops.vcpu_run() loop. But for DR6, the guest's value doesn't need to be loaded into hardware for KVM_DEBUGREG_BP_ENABLED, and SVM provides a dedicated VMCB field whereas VMX requires software to manually load the guest value, and so loading the guest's value into DR6 is handled by {svm,vmx}_vcpu_run(), i.e. is done _inside_ the core run loop. Unfortunately, saving the guest values on VM-Exit is initiated by common x86, again outside of the core run loop. If the guest modifies DR6 (in hardware, when DR interception is disabled), and then the next VM-Exit is a fastpath VM-Exit, KVM will reload hardware DR6 with vcpu->arch.dr6 and clobber the guest's actual value. The bug shows up primarily with nested VMX because KVM handles the VMX preemption timer in the fastpath, and the window between hardware DR6 being modified (in guest context) and DR6 being read by guest software is orders of magnitude larger in a nested setup. E.g. in non-nested, the VMX preemption timer would need to fire precisely between #DB injection and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the window where hardware DR6 is "dirty" extends all the way from L1 writing DR6 to VMRESUME (in L1).

When the guest accesses a DR and host userspace isn't debugging the guest, KVM disables DR interception and loads the guest's values into hardware on VM-Enter and saves them on VM-Exit. This allows the guest to access DRs at will, e.g. so that a sequence of DR accesses to configure a breakpoint only generates one VM-Exit. For DR0-DR3, the logic/behavior is identical between VMX and SVM, and also identical between KVM_DEBUGREG_BP_ENABLED (userspace debugging the guest) and KVM_DEBUGREG_WONT_EXIT (guest using DRs), and so KVM handles loading DR0-DR3 in common code, _outside_ of the core kvm_x86_ops.vcpu_run() loop. But for DR6, the guest's value doesn't need to be loaded into hardware for KVM_DEBUGREG_BP_ENABLED, and SVM provides a dedicated VMCB field whereas VMX requires software to manually load the guest value, and so loading the guest's value into DR6 is handled by {svm,vmx}_vcpu_run(), i.e. is done _inside_ the core run loop. Unfortunately, saving the guest values on VM-Exit is initiated by common x86, again outside of the core run loop. If the guest modifies DR6 (in hardware, when DR interception is disabled), and then the next VM-Exit is a fastpath VM-Exit, KVM will reload hardware DR6 with vcpu->arch.dr6 and clobber the guest's actual value. The bug shows up primarily with nested VMX because KVM handles the VMX preemption timer in the fastpath, and the window between hardware DR6 being modified (in guest context) and DR6 being read by guest software is orders of magnitude larger in a nested setup. E.g. in non-nested, the VMX preemption timer would need to fire precisely between #DB injection and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the window where hardware DR6 is "dirty" extends all the way from L1 writing DR6 to VMRESUME (in L1).

When the guest accesses a DR and host userspace isn't debugging the guest, KVM disables DR interception and loads the guest's values into hardware on VM-Enter and saves them on VM-Exit. This allows the guest to access DRs at will, e.g. so that a sequence of DR accesses to configure a breakpoint only generates one VM-Exit. For DR0-DR3, the logic/behavior is identical between VMX and SVM, and also identical between KVM_DEBUGREG_BP_ENABLED (userspace debugging the guest) and KVM_DEBUGREG_WONT_EXIT (guest using DRs), and so KVM handles loading DR0-DR3 in common code, _outside_ of the core kvm_x86_ops.vcpu_run() loop. But for DR6, the guest's value doesn't need to be loaded into hardware for KVM_DEBUGREG_BP_ENABLED, and SVM provides a dedicated VMCB field whereas VMX requires software to manually load the guest value, and so loading the guest's value into DR6 is handled by {svm,vmx}_vcpu_run(), i.e. is done _inside_ the core run loop. Unfortunately, saving the guest values on VM-Exit is initiated by common x86, again outside of the core run loop. If the guest modifies DR6 (in hardware, when DR interception is disabled), and then the next VM-Exit is a fastpath VM-Exit, KVM will reload hardware DR6 with vcpu->arch.dr6 and clobber the guest's actual value. The bug shows up primarily with nested VMX because KVM handles the VMX preemption timer in the fastpath, and the window between hardware DR6 being modified (in guest context) and DR6 being read by guest software is orders of magnitude larger in a nested setup. E.g. in non-nested, the VMX preemption timer would need to fire precisely between #DB injection and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the window where hardware DR6 is "dirty" extends all the way from L1 writing DR6 to VMRESUME (in L1).

[PATCH v5] Restrict devmem for confidential VMs

by Dan Williams

Changes since v3 [1] (note v4 was a partial re-roll, but more feedback came in requiring a v5): - Fix a kbuild robot report for a missing header include of cc_platform.h - Switch to selecting STRICT_DEVMEM and IOSTRICT_DEVMEM rather than "depends on". (Naveen) - Clarify the "SEPT violation" vs "crash" and other changelog fixups for devmem maintainers and other arch maintainers. (Dave) - Drop patch numbering since patch2 is a fix and has no dependencies on patch1 [1]: http://lore.kernel.org/174491711228.1395340.3647010925173796093.stgit@dwill… --- The original response to Nikolay's report of a "crash" (unhandled SEPT violation) triggered by /dev/mem access to private memory was "let's just turn off /dev/mem". After some machinations of x86_platform_ops to block a subset of problematic access, spelunking the history of devmem_is_allowed() returning "2" to enable some compatibility benefits while blocking access, and discovering that userspace depends buggy kernel behavior for mmap(2) of the first 1MB of memory on x86, the proposal has circled back to "disable /dev/mem". Require both STRICT_DEVMEM and IO_STRICT_DEVMEM for x86 confidential guests to close /dev/mem hole while still allowing for userspace mapping of PCI MMIO as long as the kernel and userspace are not mapping the range at the same time. The range_is_allowed() cleanup is not strictly necessary, but might as well close a 17 year-old "TODO".

[PATCH stable 6.6 00/10] bpf: track changes_pkt_data property for global functions

by Shung-Hsi Yu

Fix the bypassing of invalid packet pointer check in 6.6 by backporting the entire "bpf: track changes_pkt_data property for global functions" series[1], along with the follow up, "bpf: fix NPE when computing changes_pkt_data of program w/o subprograms" series[2]; both from Eduard. I had ran the BPF selftests after backporting, confirmed that newly added BPF selftests passes, and that no new failure observed in BPF selftests (dummy_st_ops, ns_current_pid_tgid, test_bpf_ma, and test_bpffs are failing even without this patchset applied).

[PATCH stable v6.6] riscv: kprobes: Fix wrong lengths passed to patch_text_nosync()

by Nam Cao

Unlike patch_text(), patch_text_nosync() takes the length in bytes, not number of instructions. It is therefore wrong for arch_prepare_ss_slot() to pass length=1 while patching one instruction. This bug was introduced by commit b1756750a397 ("riscv: kprobes: Use patch_text_nosync() for insn slots"). It has been fixed upstream by commit 51781ce8f448 ("riscv: Pass patch_text() the length in bytes"). However, beside fixing this bug, this commit does many other things, making it unsuitable for backporting. Fix it by properly passing the lengths in bytes.

[to-be-updated] mm-userfaultfd-prevent-busy-looping-for-tasks-with-signals-pending.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/userfaultfd: prevent busy looping for tasks with signals pending has been removed from the -mm tree. Its filename was mm-userfaultfd-prevent-busy-looping-for-tasks-with-signals-pending.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Jens Axboe <axboe(a)kernel.dk> Subject: mm/userfaultfd: prevent busy looping for tasks with signals pending Date: Wed, 23 Apr 2025 17:37:06 -0600 userfaultfd may use interruptible sleeps to wait on userspace filling a page fault, which works fine if the task can be reliably put to sleeping waiting for that. However, if the task has a normal (ie non-fatal) signal pending, then TASK_INTERRUPTIBLE sleep will simply cause schedule() to be a no-op. For a task that registers a page with userfaultfd and then proceeds to do a write from it, if that task also has a signal pending then it'll essentially busy loop from do_page_fault() -> handle_userfault() until that fault has been filled. Normally it'd be expected that the task would sleep until that happens. Here's a trace from an application doing just that: handle_userfault+0x4b8/0xa00 (P) hugetlb_fault+0xe24/0x1060 handle_mm_fault+0x2bc/0x318 do_page_fault+0x1e8/0x6f0 do_translation_fault+0x9c/0xd0 do_mem_abort+0x44/0xa0 el1_abort+0x3c/0x68 el1h_64_sync_handler+0xd4/0x100 el1h_64_sync+0x6c/0x70 fault_in_readable+0x74/0x108 (P) iomap_file_buffered_write+0x14c/0x438 blkdev_write_iter+0x1a8/0x340 vfs_write+0x20c/0x348 ksys_write+0x64/0x108 __arm64_sys_write+0x1c/0x38 where the task is looping with 100% CPU time in the above mentioned fault path. Since it's impossible to handle signals, or other conditions like TIF_NOTIFY_SIGNAL that also prevents interruptible sleeping, from the fault path, use TASK_UNINTERRUPTIBLE with a short timeout even for vmf modes that would normally ask for INTERRUPTIBLE or KILLABLE sleep.

+ mm-userfaultfd-prevent-busy-looping-for-tasks-with-signals-pending.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: mm/userfaultfd: prevent busy looping for tasks with signals pending has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-userfaultfd-prevent-busy-looping-for-tasks-with-signals-pending.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: Jens Axboe <axboe(a)kernel.dk> Subject: mm/userfaultfd: prevent busy looping for tasks with signals pending Date: Wed, 23 Apr 2025 17:37:06 -0600 userfaultfd may use interruptible sleeps to wait on userspace filling a page fault, which works fine if the task can be reliably put to sleeping waiting for that. However, if the task has a normal (ie non-fatal) signal pending, then TASK_INTERRUPTIBLE sleep will simply cause schedule() to be a no-op. For a task that registers a page with userfaultfd and then proceeds to do a write from it, if that task also has a signal pending then it'll essentially busy loop from do_page_fault() -> handle_userfault() until that fault has been filled. Normally it'd be expected that the task would sleep until that happens. Here's a trace from an application doing just that: handle_userfault+0x4b8/0xa00 (P) hugetlb_fault+0xe24/0x1060 handle_mm_fault+0x2bc/0x318 do_page_fault+0x1e8/0x6f0 do_translation_fault+0x9c/0xd0 do_mem_abort+0x44/0xa0 el1_abort+0x3c/0x68 el1h_64_sync_handler+0xd4/0x100 el1h_64_sync+0x6c/0x70 fault_in_readable+0x74/0x108 (P) iomap_file_buffered_write+0x14c/0x438 blkdev_write_iter+0x1a8/0x340 vfs_write+0x20c/0x348 ksys_write+0x64/0x108 __arm64_sys_write+0x1c/0x38 where the task is looping with 100% CPU time in the above mentioned fault path. Since it's impossible to handle signals, or other conditions like TIF_NOTIFY_SIGNAL that also prevents interruptible sleeping, from the fault path, use TASK_UNINTERRUPTIBLE with a short timeout even for vmf modes that would normally ask for INTERRUPTIBLE or KILLABLE sleep. Fatal signals will still be handled by the caller, and the timeout is short enough to hopefully not cause any issues. If this is the first invocation of this fault, eg FAULT_FLAG_TRIED isn't set, then the normal sleep mode is used.

[PATCH 0/3 V3] usb: usbtmc: Fix erroneous ioctl returns

by Dave Penkler

Recent tests with timeouts > INT_MAX produced random error returns with usbtmc_get_stb. This was caused by assigning the return value of wait_event_interruptible_timeout to an int which overflowed to negative values. Also return value on success was the remaining number of jiffies instead of 0. These patches fix all the cases where the return of wait_event_interruptible_timeout was assigned to an int and the case of the remaining jiffies return in usbtmc_get_stb.

In fact, DCN related clocks are higher when IPS2 is enabled vs RCG. RCG_IN_ACTIVE is also the default policy for another OS supported by DC, and it has faster entry/exit.

[PATCH v4 6.6] iommu: Handle race with default domain setup

by Robin Murphy

[ Upstream commit b46064a18810bad3aea089a79993ca5ea7a3d2b2 ] It turns out that deferred default domain creation leaves a subtle race window during iommu_device_register() wherein a client driver may asynchronously probe in parallel and get as far as performing DMA API operations with dma-direct, only to be switched to iommu-dma underfoot once the default domain attachment finally happens, with obviously disastrous consequences. Even the wonky of_iommu_configure() path is at risk, since iommu_fwspec_init() will no longer defer client probe as the instance ops are (necessarily) already registered, and the "replay" iommu_probe_device() call can see dev->iommu_group already set and so think there's nothing to do either. Fortunately we already have the right tool in the right place in the form of iommu_device_use_default_domain(), which just needs to ensure that said default domain is actually ready to *be* used. Deferring the client probe shouldn't have too much impact, given that this only happens while the IOMMU driver is probing, and thus due to kick the deferred probe list again once it finishes. [ Backport: The above is true for mainline, but here we still have arch_setup_dma_ops() to worry about, which is not replayed if the default domain happens to be allocated *between* that call and subsequently reaching iommu_device_use_default_domain(), so we need an additional earlier check to cover that case. Also we're now back before the nominal commit 98ac73f99bc4 so we need to tweak the logic to depend on IOMMU_DMA as well, to avoid falsely deferring on architectures not using default domains (but also tegra-smmu, which we can identify via set_platform_dma). This then serves us back as far as f188056352bc, where this specific form of the problem first arises. ] Reported-by: Charan Teja Kalla <quic_charante(a)quicinc.com> Fixes: 98ac73f99bc4 ("iommu: Require a default_domain for all iommu drivers") Fixes: f188056352bc ("iommu: Avoid locking/unlocking for iommu_probe_device()") Link: https://lore.kernel.org/r/e88b94c9b575034a2c98a48b3d383654cbda7902.17407532… Signed-off-by: Robin Murphy <robin.murphy(a)arm.com> --- OK, c8cc2655cc6c might cherry-pick, but I really should have tried building it first... -EMORECOFFEE Trying again, I think this should work for Tegra without being disruptive to anything else. drivers/iommu/iommu.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/drivers/iommu/iommu.c b/drivers/iommu/iommu.c index 3f1029c0825e..f2b3a4e2e54f 100644 --- a/drivers/iommu/iommu.c +++ b/drivers/iommu/iommu.c @@ -566,6 +566,18 @@ int iommu_probe_device(struct device *dev) mutex_lock(&iommu_probe_device_lock); ret = __iommu_probe_device(dev, NULL); mutex_unlock(&iommu_probe_device_lock); + + /* + * The dma_configure replay paths need bus_iommu_probe() to + * finish before they can call arch_setup_dma_ops() + */ + if (IS_ENABLED(CONFIG_IOMMU_DMA) && !ret && dev->iommu_group) { + mutex_lock(&dev->iommu_group->mutex); + if (!dev->iommu_group->default_domain && + !dev_iommu_ops(dev)->set_platform_dma_ops) + ret = -EPROBE_DEFER; + mutex_unlock(&dev->iommu_group->mutex); + } if (ret) return ret; @@ -3149,6 +3161,12 @@ int iommu_device_use_default_domain(struct device *dev) return 0; mutex_lock(&group->mutex); + /* We may race against bus_iommu_probe() finalising groups here */ + if (IS_ENABLED(CONFIG_IOMMU_DMA) && !group->default_domain && + !dev_iommu_ops(dev)->set_platform_dma_ops) { + ret = -EPROBE_DEFER; + goto unlock_out; + } if (group->owner_cnt) { if (group->owner || !iommu_is_default_domain(group) || !xa_empty(&group->pasid_array)) { -- 2.39.2.101.g768bb238c484.dirty

The issue has been observed with Raspberry Pi devices at least since 4.14 (see [1], bug report for their downstream kernel), as well as with Nvidia devices [2] in 2020, where disabling interrupts was the vendor-suggested workaround (together with the claim that phylib changes in 4.9 made the interrupt handling in lan78xx incompatible). Iperf reports well over 900Mbits/sec per direction with client in --dualtest mode, so there does not seem to be a significant impact on throughput (lan88xx device connected via switch to the peer).

The issue has been observed with Raspberry Pi devices at least since 4.14 (see [1], bug report for their downstream kernel), as well as with Nvidia devices [2] in 2020, where disabling interrupts was the vendor-suggested workaround (together with the claim that phylib changes in 4.9 made the interrupt handling in lan78xx incompatible). Iperf reports well over 900Mbits/sec per direction with client in --dualtest mode, so there does not seem to be a significant impact on throughput (lan88xx device connected via switch to the peer).

Older kernels like 6.6 and lower may not compile with GCC15 due to -std=gnu23

Hi all, GCC 15 changed the default C standard dialect from gnu17 to gnu23, which should not have impacted the kernel because it explicitly requests the gnu11 standard in the main Makefile.

[PATCH 3/3] HID: wacom: fix kobject reference count leak

by Qasim Ijaz

When sysfs_create_files() fails in wacom_initialize_remotes() the error is returned and the cleanup action will not have been registered yet. As a result the kobject’s refcount is never dropped, so the kobject can never be freed leading to a reference leak. Fix this by calling kobject_put() before returning.

[PATCH 1/3] HID: wacom: fix memory leak on kobject creation failure

by Qasim Ijaz

During wacom_initialize_remotes() a fifo buffer is allocated with kfifo_alloc() and later a cleanup action is registered during devm_add_action_or_reset() to clean it up. However if the code fails to create a kobject and register it with sysfs the code simply returns -ENOMEM before the cleanup action is registered leading to a memory leak. Fix this by ensuring the fifo is freed when the kobject creation and registration process fails.

[PATCH v1] usb: typec: tcpm: delay SNK_TRY_WAIT_DEBOUNCE to SRC_TRYWAIT transition

by RD Babiera

This patch fixes Type-C Compliance Test TD 4.7.6 - Try.SNK DRP Connect SNKAS. The compliance tester moves into SNK_UNATTACHED during toggling and expects the PUT to apply Rp after tPDDebounce of detection. If the port is in SNK_TRY_WAIT_DEBOUNCE, it will move into SRC_TRYWAIT immediately and apply Rp. This violates TD 4.7.5.V.3, where the tester confirms that the PUT attaches Rp after the transitions to Unattached.SNK for tPDDebounce. Change the tcpm_set_state delay between SNK_TRY_WAIT_DEBOUNCE and SRC_TRYWAIT to tPDDebounce.

[PATCH v2] x86/sev: Fix making shared pages private during kdump

From: Ashish Kalra <ashish.kalra(a)amd.com> When the shared pages are being made private during kdump preparation there are additional checks to handle shared GHCB pages. These additional checks include handling the case of GHCB page being contained within a huge page. There is a bug in this additional check for GHCB page contained within a huge page which causes any shared page just below the per-cpu GHCB getting skipped from being transitioned back to private before kdump preparation which subsequently causes a 0x404 #VC exception when this shared page is accessed later while dumping guest memory during vmcore generation via kdump.

[PATCH] ASoC: fsl: fsl_qmc_audio: Reset audio data pointers on TRIGGER_START event

by Herve Codina

On SNDRV_PCM_TRIGGER_START event, audio data pointers are not reset. This leads to wrong data buffer usage when multiple TRIGGER_START are received and ends to incorrect buffer usage between the user-space and the driver. Indeed, the driver can read data that are not already set by the user-space or the user-space and the driver are writing and reading the same area. Fix that resetting data pointers on each SNDRV_PCM_TRIGGER_START events.

[PATCH] accel/ivpu: Add handling of VPU_JSM_STATUS_MVNCI_CONTEXT_VIOLATION_HW

by Jacek Lawrynowicz

From: Karol Wachowski <karol.wachowski(a)intel.com> commit dad945c27a42dfadddff1049cf5ae417209a8996 upstream. Trigger recovery of the NPU upon receiving HW context violation from the firmware. The context violation error is a fatal error that prevents any subsequent jobs from being executed. Without this fix it is necessary to reload the driver to restore the NPU operational state.

[tip: perf/urgent] perf/x86/intel: KVM: Mask PEBS_ENABLE loaded for guest with vCPU's value.

by tip-bot2 for Sean Christopherson

The following commit has been merged into the perf/urgent branch of tip: Commit-ID: 58f6217e5d0132a9f14e401e62796916aa055c1b Gitweb: https://git.kernel.org/tip/58f6217e5d0132a9f14e401e62796916aa055c1b Author: Sean Christopherson <seanjc(a)google.com> AuthorDate: Fri, 25 Apr 2025 17:13:55 -07:00 Committer: Peter Zijlstra <peterz(a)infradead.org> CommitterDate: Wed, 30 Apr 2025 13:58:29 +02:00 perf/x86/intel: KVM: Mask PEBS_ENABLE loaded for guest with vCPU's value. When generating the MSR_IA32_PEBS_ENABLE value that will be loaded on VM-Entry to a KVM guest, mask the value with the vCPU's desired PEBS_ENABLE value. Consulting only the host kernel's host vs. guest masks results in running the guest with PEBS enabled even when the guest doesn't want to use PEBS. Because KVM uses perf events to proxy the guest virtual PMU, simply looking at exclude_host can't differentiate between events created by host userspace, and events created by KVM on behalf of the guest. Running the guest with PEBS unexpectedly enabled typically manifests as crashes due to a near-infinite stream of #PFs. E.g. if the guest hasn't written MSR_IA32_DS_AREA, the CPU will hit page faults on address '0' when trying to record PEBS events. The issue is most easily reproduced by running `perf kvm top` from before commit 7b100989b4f6 ("perf evlist: Remove __evlist__add_default") (after which, `perf kvm top` effectively stopped using PEBS). The userspace side of perf creates a guest-only PEBS event, which intel_guest_get_msrs() misconstrues a guest-*owned* PEBS event. Arguably, this is a userspace bug, as enabling PEBS on guest-only events simply cannot work, and userspace can kill VMs in many other ways (there is no danger to the host). However, even if this is considered to be bad userspace behavior, there's zero downside to perf/KVM restricting PEBS to guest-owned events. Note, commit 854250329c02 ("KVM: x86/pmu: Disable guest PEBS temporarily in two rare situations") fixed the case where host userspace is profiling KVM *and* userspace, but missed the case where userspace is profiling only KVM.

[PATCH V2 1/5] perf/x86/intel: Only check the group flag for X86 leader

by kan.liang＠linux.intel.com

From: Kan Liang <kan.liang(a)linux.intel.com> A warning in intel_pmu_lbr_counters_reorder() may be triggered by below perf command. perf record -e "{cpu-clock,cycles/call-graph="lbr"/}" -- sleep 1 It's because the group is mistakenly treated as a branch counter group. The hw.flags of the leader are used to determine whether a group is a branch counters group. However, the hw.flags is only available for a hardware event. The field to store the flags is a union type. For a software event, it's a hrtimer. The corresponding bit may be set if the leader is a software event. For a branch counter group and other groups that have a group flag (e.g., topdown, PEBS counters snapshotting, and ACR), the leader must be a X86 event. Check the X86 event before checking the flag. The patch only fixes the issue for the branch counter group. The following patch will fix the other groups. There may be an alternative way to fix the issue by moving the hw.flags out of the union type. It should work for now. But it's still possible that the flags will be used by other types of events later. As long as that type of event is used as a leader, a similar issue will be triggered. So the alternative way is dropped.

[PATCH v2 00/23] Add support for HEVC and VP9 codecs in decoder

by Dikshita Agarwal

Hi All, This patch series adds initial support for the HEVC(H.265) and VP9 codecs in iris decoder. The objective of this work is to extend the decoder's capabilities to handle HEVC and VP9 codec streams, including necessary format handling and buffer management. In addition, the series also includes a set of fixes to address issues identified during testing of these additional codecs. These patches also address the comments and feedback received from the RFC patches previously sent. I have made the necessary improvements based on the community's suggestions. Changes in v2: - Added Changes to make sure all buffers are released in session close (bryna) - Added tracking for flush responses to fix a timing issue. - Added a handling to fix timing issue in reconfig - Splitted patch 06/20 in two patches (Bryan) - Added missing fixes tag (bryan) - Updated fluster report (Nicolas) - Link to v1: https://lore.kernel.org/r/20250408-iris-dec-hevc-vp9-v1-0-acd258778bd6@quic… Changes sinces RFC: - Added additional fixes to address issues identified during further testing. - Moved typo fix to a seperate patch [Neil] - Reordered the patches for better logical flow and clarity [Neil, Dmitry] - Added fixes tag wherever applicable [Neil, Dmitry] - Removed the default case in the switch statement for codecs [Bryan] - Replaced if-else statements with switch-case [Bryan] - Added comments for mbpf [Bryan] - RFC: https://lore.kernel.org/linux-media/20250305104335.3629945-1-quic_dikshita@… This patch series depends on [1] & [2] [1] https://lore.kernel.org/linux-media/20250417-topic-sm8x50-iris-v10-v7-0-f02… [2] https://lore.kernel.org/linux-media/20250424-qcs8300_iris-v5-0-f118f505c300… These patches are tested on SM8250 and SM8550 with v4l2-ctl and Gstreamer for HEVC and VP9 decoders, at the same time ensured that the existing H264 decoder functionality remains uneffected. Note: 1 of the fluster compliance test is fixed with firmware [3] [3]: https://lore.kernel.org/linux-firmware/1a511921-446d-cdc4-0203-084c88a5dc1e… The result of fluster test on SM8550: 131/147 testcases passed while testing JCT-VC-HEVC_V1 with GStreamer-H.265-V4L2-Gst1.0.

[PATCH] accel/ivpu: Increase state dump msg timeout

by Jacek Lawrynowicz

Increase JMS message state dump command timeout to 100 ms. On some platforms, the FW may take a bit longer than 50 ms to dump its state to the log buffer and we don't want to miss any debug info during TDR.

[to-be-updated] kasan-avoid-sleepable-page-allocation-from-atomic-context.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: kasan: avoid sleepable page allocation from atomic context has been removed from the -mm tree. Its filename was kasan-avoid-sleepable-page-allocation-from-atomic-context.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Alexander Gordeev <agordeev(a)linux.ibm.com> Subject: kasan: avoid sleepable page allocation from atomic context Date: Tue, 29 Apr 2025 18:08:41 +0200 apply_to_pte_range() enters the lazy MMU mode and then invokes kasan_populate_vmalloc_pte() callback on each page table walk iteration. However, the callback can go into sleep when trying to allocate a single page, e.g. if an architecutre disables preemption on lazy MMU mode enter. On s390 with the call sequences arch_enter_lazy_mmu_mode() -> preempt_enable() and arch_leave_lazy_mmu_mode() -> preempt_disable(), such a crash occurs: [ 553.332108] preempt_count: 1, expected: 0 [ 553.332117] no locks held by multipathd/2116.

[PATCH v3] net: mdio: mux-meson-gxl: set reversed bit when using internal phy

by Da Xue

This bit is necessary to receive packets from the internal PHY. Without this bit set, no activity occurs on the interface. Normally u-boot sets this bit, but if u-boot is compiled without net support, the interface will be up but without any activity. The vendor SDK sets this bit along with the PHY_ID bits.

Feedback on New Kafka Project

by Xiaorui Wang

Greetings, I saw you were interested in many open source project, so I wanted to share a relevant open source project I'm working on. AutoMQ is a Kafka solution developed on object storage. This offers several distinct advantages: - 10x more cost-effective than Apache Kafka. - Partition reassignment 800x faster than Kafka. - 5x higher throughput in catch-up read. I'm pleased to announce that AutoMQ has successfully simplified the operation and maintenance of Apache Kafka for Grab.com, which has greatly lowered their cloud expenditures. Is this something that could be beneficial? I'd love to hear any feedback you might have! (If it's not relevant, no problem – I won't bother you again!) Sincerely, Xiaorui github.com/automq/automq

[PATCH net v3 0/2] address EEE regressions on KSZ switches since v6.9 (v6.14+)

by Oleksij Rempel

This patch series addresses a regression in Energy Efficient Ethernet (EEE) handling for KSZ switches with integrated PHYs, introduced in kernel v6.9 by commit fe0d4fd9285e ("net: phy: Keep track of EEE configuration"). The first patch updates the DSA driver to allow phylink to properly manage PHY EEE configuration. Since integrated PHYs handle LPI internally and ports without integrated PHYs do not document MAC-level LPI support, dummy MAC LPI callbacks are provided. The second patch removes outdated EEE workarounds from the micrel PHY driver, as they are no longer needed with correct phylink handling. This series addresses the regression for mainline and kernels starting from v6.14. It is not easily possible to fully fix older kernels due to missing infrastructure changes. Tested on KSZ9893 hardware. Oleksij Rempel (2): net: dsa: microchip: let phylink manage PHY EEE configuration on KSZ switches net: phy: micrel: remove KSZ9477 EEE quirks now handled by phylink drivers/net/dsa/microchip/ksz_common.c | 134 +++++++++++++++++++------ drivers/net/phy/micrel.c | 7 -- include/linux/micrel_phy.h | 1 - 3 files changed, 106 insertions(+), 36 deletions(-) -- 2.39.5

[PATCH v3 1/3] firmware: arm_scmi: Ensure that the message-id supports fastchannel

by Cristian Marussi

From: Sibi Sankar <quic_sibis(a)quicinc.com> Currently the perf and powercap protocol relies on the protocol domain attributes, which just ensures that one fastchannel per domain, before instantiating fastchannels for all possible message-ids. Fix this by ensuring that each message-id supports fastchannel before initialization. Logs: scmi: Failed to get FC for protocol 13 [MSG_ID:6 / RES_ID:0] - ret:-95. Using regular messaging. scmi: Failed to get FC for protocol 13 [MSG_ID:6 / RES_ID:1] - ret:-95. Using regular messaging. scmi: Failed to get FC for protocol 13 [MSG_ID:6 / RES_ID:2] - ret:-95.

[PATCH] drm: Select DRM_KMS_HELPER from DRM_DEBUG_DP_MST_TOPOLOGY_REFS

by Janne Grunau via B4 Relay

From: Janne Grunau <j(a)jannau.net> Using "depends on" and "select" for the same Kconfig symbol is known to cause circular dependencies (cmp. "Kconfig recursive dependency limitations" in Documentation/kbuild/kconfig-language.rst. DRM drivers are selecting drm helpers so do the same for DRM_DEBUG_DP_MST_TOPOLOGY_REFS. Fixes following circular dependency reported on x86 for the downstream Asahi Linux tree: error: recursive dependency detected! symbol DRM_KMS_HELPER is selected by DRM_GEM_SHMEM_HELPER symbol DRM_GEM_SHMEM_HELPER is selected by RUST_DRM_GEM_SHMEM_HELPER symbol RUST_DRM_GEM_SHMEM_HELPER is selected by DRM_ASAHI symbol DRM_ASAHI depends on RUST symbol RUST depends on CALL_PADDING symbol CALL_PADDING depends on OBJTOOL symbol OBJTOOL is selected by STACK_VALIDATION symbol STACK_VALIDATION depends on UNWINDER_FRAME_POINTER symbol UNWINDER_FRAME_POINTER is part of choice block at arch/x86/Kconfig.debug:224 symbol <choice> unknown is visible depending on UNWINDER_GUESS symbol UNWINDER_GUESS prompt is visible depending on STACKDEPOT symbol STACKDEPOT is selected by DRM_DEBUG_DP_MST_TOPOLOGY_REFS symbol DRM_DEBUG_DP_MST_TOPOLOGY_REFS depends on DRM_KMS_HELPER Fixes: 12a280c72868 ("drm/dp_mst: Add topology ref history tracking for debugging") Cc: stable(a)vger.kernel.org Signed-off-by: Janne Grunau <j(a)jannau.net> --- drivers/gpu/drm/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/Kconfig b/drivers/gpu/drm/Kconfig index fbef3f471bd0e5101699cf576542f7350bea3982..bd228dc77e99b4356b09de02d9001237eb2423e2 100644 --- a/drivers/gpu/drm/Kconfig +++ b/drivers/gpu/drm/Kconfig @@ -188,7 +188,7 @@ config DRM_DEBUG_DP_MST_TOPOLOGY_REFS bool "Enable refcount backtrace history in the DP MST helpers" depends on STACKTRACE_SUPPORT select STACKDEPOT - depends on DRM_KMS_HELPER + select DRM_KMS_HELPER depends on DEBUG_KERNEL depends on EXPERT help --- base-commit: 2014c95afecee3e76ca4a56956a936e23283f05b change-id: 20250304-drm_debug_dp_mst_topo_kconfig-a112904ba611 Best regards, -- Janne Grunau <j(a)jannau.net>

[PATCH 6.6] iommu: Handle race with default domain setup

by Robin Murphy

[ Upstream commit b46064a18810bad3aea089a79993ca5ea7a3d2b2 ] It turns out that deferred default domain creation leaves a subtle race window during iommu_device_register() wherein a client driver may asynchronously probe in parallel and get as far as performing DMA API operations with dma-direct, only to be switched to iommu-dma underfoot once the default domain attachment finally happens, with obviously disastrous consequences. Even the wonky of_iommu_configure() path is at risk, since iommu_fwspec_init() will no longer defer client probe as the instance ops are (necessarily) already registered, and the "replay" iommu_probe_device() call can see dev->iommu_group already set and so think there's nothing to do either. Fortunately we already have the right tool in the right place in the form of iommu_device_use_default_domain(), which just needs to ensure that said default domain is actually ready to *be* used. Deferring the client probe shouldn't have too much impact, given that this only happens while the IOMMU driver is probing, and thus due to kick the deferred probe list again once it finishes. [ Backport: The above is true for mainline, but here we still have arch_setup_dma_ops() to worry about, which is not replayed if the default domain happens to be allocated *between* that call and subsequently reaching iommu_device_use_default_domain(), so we need an additional earlier check to cover that case. Also we're now back before the nominal commit 98ac73f99bc4 so we need to tweak the logic to depend on IOMMU_DMA as well, to avoid falsely deferring on architectures not using default domains. This then serves us back as far as f188056352bc, where this specific form of the problem first arises. ] Reported-by: Charan Teja Kalla <quic_charante(a)quicinc.com> Fixes: 98ac73f99bc4 ("iommu: Require a default_domain for all iommu drivers") Fixes: f188056352bc ("iommu: Avoid locking/unlocking for iommu_probe_device()") Link: https://lore.kernel.org/r/e88b94c9b575034a2c98a48b3d383654cbda7902.17407532… Signed-off-by: Robin Murphy <robin.murphy(a)arm.com> --- drivers/iommu/iommu.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/drivers/iommu/iommu.c b/drivers/iommu/iommu.c index 3f1029c0825e..29b48a6a0275 100644 --- a/drivers/iommu/iommu.c +++ b/drivers/iommu/iommu.c @@ -566,6 +566,17 @@ int iommu_probe_device(struct device *dev) mutex_lock(&iommu_probe_device_lock); ret = __iommu_probe_device(dev, NULL); mutex_unlock(&iommu_probe_device_lock); + + /* + * The dma_configure replay paths need bus_iommu_probe() to + * finish before they can call arch_setup_dma_ops() + */ + if (IS_ENABLED(CONFIG_IOMMU_DMA) && !ret && dev->iommu_group) { + mutex_lock(&dev->iommu_group->mutex); + if (!dev->iommu_group->default_domain) + ret = -EPROBE_DEFER; + mutex_unlock(&dev->iommu_group->mutex); + } if (ret) return ret; @@ -3149,6 +3160,11 @@ int iommu_device_use_default_domain(struct device *dev) return 0; mutex_lock(&group->mutex); + /* We may race against bus_iommu_probe() finalising groups here */ + if (!group->default_domain) { + ret = -EPROBE_DEFER; + goto unlock_out; + } if (group->owner_cnt) { if (group->owner || !iommu_is_default_domain(group) || !xa_empty(&group->pasid_array)) { -- 2.39.2.101.g768bb238c484.dirty

[PATCH] drm/v3d: Add job to pending list if the reset was skipped

by Maíra Canal

When a CL/CSD job times out, we check if the GPU has made any progress since the last timeout. If so, instead of resetting the hardware, we skip the reset and let the timer get rearmed. This gives long-running jobs a chance to complete. However, when `timedout_job()` is called, the job in question is removed from the pending list, which means it won't be automatically freed through `free_job()`. Consequently, when we skip the reset and keep the job running, the job won't be freed when it finally completes. This situation leads to a memory leak, as exposed in [1]. Similarly to commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when GPU is still active"), this patch ensures the job is put back on the pending list when extending the timeout.

[PATCH 6.12.y v2 1/5] Revert "net: dsa: mv88e6xxx: fix internal PHYs for 6320 family"

by Marek Behún

This reverts commit 2b27df6852444b76724f5d425826a38581d63407. For stable 6.12 it was misapplied to wrong entries of the `mv88e6xxx_table` array: instead of the MV88E6320 and MV88E6321 entries it was applied to the MV88E6240 and MV88E6352 entries.

[PATCH net v2 0/2] address EEE regressions on KSZ switches since v6.9 (v6.14+)

by Oleksij Rempel

This patch series addresses a regression in Energy Efficient Ethernet (EEE) handling for KSZ switches with integrated PHYs, introduced in kernel v6.9 by commit fe0d4fd9285e ("net: phy: Keep track of EEE configuration"). The first patch updates the DSA driver to allow phylink to properly manage PHY EEE configuration. Since integrated PHYs handle LPI internally and ports without integrated PHYs do not document MAC-level LPI support, dummy MAC LPI callbacks are provided. The second patch removes outdated EEE workarounds from the micrel PHY driver, as they are no longer needed with correct phylink handling. This series addresses the regression for mainline and kernels starting from v6.14. It is not easily possible to fully fix older kernels due to missing infrastructure changes. Tested on KSZ9893 hardware. Oleksij Rempel (2): net: dsa: microchip: let phylink manage PHY EEE configuration on KSZ switches net: phy: micrel: remove KSZ9477 EEE quirks now handled by phylink drivers/net/dsa/microchip/ksz_common.c | 134 +++++++++++++++++++------ drivers/net/phy/micrel.c | 7 -- include/linux/micrel_phy.h | 1 - 3 files changed, 106 insertions(+), 36 deletions(-) -- 2.39.5

Mhm, why has that patch been picked up for backporting? It's a cleanup and not a bug fix.

[PATCH net v1 0/2] address EEE regressions on KSZ switches since v6.9 (v6.14+)

by Oleksij Rempel

This patch series addresses a regression in Energy Efficient Ethernet (EEE) handling for KSZ switches with integrated PHYs, introduced in kernel v6.9 by commit fe0d4fd9285e ("net: phy: Keep track of EEE configuration"). The first patch updates the DSA driver to allow phylink to properly manage PHY EEE configuration. Since integrated PHYs handle LPI internally and ports without integrated PHYs do not document MAC-level LPI support, dummy MAC LPI callbacks are provided. The second patch removes outdated EEE workarounds from the micrel PHY driver, as they are no longer needed with correct phylink handling. This series addresses the regression for mainline and kernels starting from v6.14. It is not easily possible to fully fix older kernels due to missing infrastructure changes. Tested on KSZ9893 hardware. Oleksij Rempel (2): net: dsa: microchip: let phylink manage PHY EEE configuration on KSZ switches net: phy: micrel: remove KSZ9477 EEE quirks now handled by phylink drivers/net/dsa/microchip/ksz_common.c | 97 ++++++++++++++++++-------- drivers/net/phy/micrel.c | 7 -- include/linux/micrel_phy.h | 1 - 3 files changed, 69 insertions(+), 36 deletions(-) -- 2.39.5

Build failure due to backport of "bpf: Add namespace to BPF internal symbols"

by Shung-Hsi Yu

Hi Sasha, bpf-add-namespace-to-bpf-internal-symbols.patch is stable-queue.git seems like the culprit responsible for build failure in stable 6.12 and earlier (log below). The reason is likely due to the lack of commit cdd30ebb1b9f ("module: Convert symbol namespace to string literal") before v6.13. Getting rid of the quotes s/"BPF_INTERNAL"/BPF_INTERNAL/ probably would be enough to fix it.

[PATCH V3] arm64/boot: Enable EL2 requirements for FEAT_PMUv3p9

by Anshuman Khandual

FEAT_PMUv3p9 registers such as PMICNTR_EL0, PMICFILTR_EL0, and PMUACR_EL1 access from EL1 requires appropriate EL2 fine grained trap configuration via FEAT_FGT2 based trap control registers HDFGRTR2_EL2 and HDFGWTR2_EL2. Otherwise such register accesses will result in traps into EL2. Add a new helper __init_el2_fgt2() which initializes FEAT_FGT2 based fine grained trap control registers HDFGRTR2_EL2 and HDFGWTR2_EL2 (setting the bits nPMICNTR_EL0, nPMICFILTR_EL0 and nPMUACR_EL1) to enable access into PMICNTR_EL0, PMICFILTR_EL0, and PMUACR_EL1 registers. Also update booting.rst with SCR_EL3.FGTEn2 requirement for all FEAT_FGT2 based registers to be accessible in EL2.

[PATCH v2] 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 within amdgpu_ras_do_page_retirement(), which also does not check the return value.

[PATCH] fs/erofs/fileio: call erofs_onlinefolio_split() after bio_add_folio()

by Max Kellermann

If bio_add_folio() fails (because it is full), erofs_fileio_scan_folio() needs to submit the I/O request via erofs_fileio_rq_submit() and allocate a new I/O request with an empty `struct bio`. Then it retries the bio_add_folio() call. However, at this point, erofs_onlinefolio_split() has already been called which increments `folio->private`; the retry will call erofs_onlinefolio_split() again, but there will never be a matching erofs_onlinefolio_end() call. This leaves the folio locked forever and all waiters will be stuck in folio_wait_bit_common(). This bug has been added by commit ce63cb62d794 ("erofs: support unencoded inodes for fileio"), but was practically unreachable because there was room for 256 folios in the `struct bio` - until commit 9f74ae8c9ac9 ("erofs: shorten bvecs[] for file-backed mounts") which reduced the array capacity to 16 folios. It was now trivial to trigger the bug by manually invoking readahead from userspace, e.g.: posix_fadvise(fd, 0, st.st_size, POSIX_FADV_WILLNEED); This should be fixed by invoking erofs_onlinefolio_split() only after bio_add_folio() has succeeded. This is safe: asynchronous completions invoking erofs_onlinefolio_end() will not unlock the folio because erofs_fileio_scan_folio() is still holding a reference to be released by erofs_onlinefolio_end() at the end.

[PATCH v2] usb: cdnsp: fix L1 resume issue for RTL_REVISION_NEW_LPM version

by Pawel Laszczak

The controllers with rtl version larger than RTL_REVISION_NEW_LPM (0x00002700) has bug which causes that controller doesn't resume from L1 state. It happens if after receiving LPM packet controller starts transitioning to L1 and in this moment the driver force resuming by write operation to PORTSC.PLS. It's corner case and happens when write operation to PORTSC occurs during device delay before transitioning to L1 after transmitting ACK time (TL1TokenRetry). Forcing transition from L1->L0 by driver for revision larger than RTL_REVISION_NEW_LPM is not needed, so driver can simply fix this issue through block call of cdnsp_force_l0_go function.

[PATCH] configfs-tsm-report: Fix NULL dereference of tsm_ops

by Dan Williams

Unlike sysfs, the lifetime of configfs objects is controlled by userspace. There is no mechanism for the kernel to find and delete all created config-items. Instead, the configfs-tsm-report mechanism has an expectation that tsm_unregister() can happen at any time and cause established config-item access to start failing. That expectation is not fully satisfied. While tsm_report_read(), tsm_report_{is,is_bin}_visible(), and tsm_report_make_item() safely fail if tsm_ops have been unregistered, tsm_report_privlevel_store() tsm_report_provider_show() fail to check for ops registration. Add the missing checks for tsm_ops having been removed. Now, in supporting the ability for tsm_unregister() to always succeed, it leaves the problem of what to do with lingering config-items. The expectation is that the admin that arranges for the ->remove() (unbind) of the ${tsm_arch}-guest driver is also responsible for deletion of all open config-items. Until that deletion happens, ->probe() (reload / bind) of the ${tsm_arch}-guest driver fails. This allows for emergency shutdown / revocation of attestation interfaces, and requires coordinated restart.

[REGRESSION] 6.14.3 panic - kernel NULL pointer dereference in htb_dequeue

by Alan J. Wylie

#regzbot introduced: 6.14.2..6.14.3 Since 6.14.3 I have been seeing random panics, all in htb_dequeue. 6.14.2 was fine. One only happened 8 hours after the reboot, so bisecting would be prolonged, since I have no idea what is triggering the crash. I've captured three panics with netconsole. All are very similar. I've also included the script I use to initialise tc. As well as when the ppp over ethernet interface comes up, I also run this every 5 minutes as a cron job since my ADSL line can fluctuate between 22 and 30 Mb/s. However, from the timings of the last few lines in /var/log/messages before the crash, it doesn't seem that this is directly related. Finally, I've decoded the first panic.

[PATCH] f2fs: fix to do sanity check on sit_bitmap_size

by Chao Yu

w/ below testcase, resize will generate a corrupted image which contains inconsistent metadata, so when mounting such image, it will trigger kernel panic: touch img truncate -s $((512*1024*1024*1024)) img mkfs.f2fs -f img $((256*1024*1024)) resize.f2fs -s -i img -t $((1024*1024*1024)) mount img /mnt/f2fs ------------[ cut here ]------------ kernel BUG at fs/f2fs/segment.h:863!

[PATCH net V3] amd-xgbe: Fix to ensure dependent features are toggled with RX checksum offload

by Vishal Badole

According to the XGMAC specification, enabling features such as Layer 3 and Layer 4 Packet Filtering, Split Header and Virtualized Network support automatically selects the IPC Full Checksum Offload Engine on the receive side. When RX checksum offload is disabled, these dependent features must also be disabled to prevent abnormal behavior caused by mismatched feature dependencies. Ensure that toggling RX checksum offload (disabling or enabling) properly disables or enables all dependent features, maintaining consistent and expected behavior in the network device. v2->v3: ------- - Removed RSS feature toggling as checksum offloading functions correctly without it v1->v2: ------- - Combine 2 patches into a single patch - Update the "Fix: tag" - Add necessary changes to support earlier versions of the hardware as well Cc: stable(a)vger.kernel.org Fixes: 1a510ccf5869 ("amd-xgbe: Add support for VXLAN offload capabilities") Signed-off-by: Vishal Badole <Vishal.Badole(a)amd.com> --- drivers/net/ethernet/amd/xgbe/xgbe-desc.c | 9 +++++++-- drivers/net/ethernet/amd/xgbe/xgbe-dev.c | 24 +++++++++++++++++++++-- drivers/net/ethernet/amd/xgbe/xgbe-drv.c | 11 +++++++++-- drivers/net/ethernet/amd/xgbe/xgbe.h | 4 ++++ 4 files changed, 42 insertions(+), 6 deletions(-) diff --git a/drivers/net/ethernet/amd/xgbe/xgbe-desc.c b/drivers/net/ethernet/amd/xgbe/xgbe-desc.c index 230726d7b74f..d41b58fad37b 100644 --- a/drivers/net/ethernet/amd/xgbe/xgbe-desc.c +++ b/drivers/net/ethernet/amd/xgbe/xgbe-desc.c @@ -373,8 +373,13 @@ static int xgbe_map_rx_buffer(struct xgbe_prv_data *pdata, } /* Set up the header page info */ - xgbe_set_buffer_data(&rdata->rx.hdr, &ring->rx_hdr_pa, - XGBE_SKB_ALLOC_SIZE); + if (pdata->netdev->features & NETIF_F_RXCSUM) { + xgbe_set_buffer_data(&rdata->rx.hdr, &ring->rx_hdr_pa, + XGBE_SKB_ALLOC_SIZE); + } else { + xgbe_set_buffer_data(&rdata->rx.hdr, &ring->rx_hdr_pa, + pdata->rx_buf_size); + } /* Set up the buffer page info */ xgbe_set_buffer_data(&rdata->rx.buf, &ring->rx_buf_pa, diff --git a/drivers/net/ethernet/amd/xgbe/xgbe-dev.c b/drivers/net/ethernet/amd/xgbe/xgbe-dev.c index 7a923b6e83df..d0a35aab7355 100644 --- a/drivers/net/ethernet/amd/xgbe/xgbe-dev.c +++ b/drivers/net/ethernet/amd/xgbe/xgbe-dev.c @@ -321,6 +321,18 @@ static void xgbe_config_sph_mode(struct xgbe_prv_data *pdata) XGMAC_IOWRITE_BITS(pdata, MAC_RCR, HDSMS, XGBE_SPH_HDSMS_SIZE); } +static void xgbe_disable_sph_mode(struct xgbe_prv_data *pdata) +{ + unsigned int i; + + for (i = 0; i < pdata->channel_count; i++) { + if (!pdata->channel[i]->rx_ring) + break; + + XGMAC_DMA_IOWRITE_BITS(pdata->channel[i], DMA_CH_CR, SPH, 0); + } +} + static int xgbe_write_rss_reg(struct xgbe_prv_data *pdata, unsigned int type, unsigned int index, unsigned int val) { @@ -3750,8 +3762,12 @@ static int xgbe_init(struct xgbe_prv_data *pdata) xgbe_config_tx_coalesce(pdata); xgbe_config_rx_buffer_size(pdata); xgbe_config_tso_mode(pdata); - xgbe_config_sph_mode(pdata); - xgbe_config_rss(pdata); + + if (pdata->netdev->features & NETIF_F_RXCSUM) { + xgbe_config_sph_mode(pdata); + xgbe_config_rss(pdata); + } + desc_if->wrapper_tx_desc_init(pdata); desc_if->wrapper_rx_desc_init(pdata); xgbe_enable_dma_interrupts(pdata); @@ -3910,5 +3926,9 @@ void xgbe_init_function_ptrs_dev(struct xgbe_hw_if *hw_if) hw_if->disable_vxlan = xgbe_disable_vxlan; hw_if->set_vxlan_id = xgbe_set_vxlan_id; + /* For Split Header*/ + hw_if->enable_sph = xgbe_config_sph_mode; + hw_if->disable_sph = xgbe_disable_sph_mode; + DBGPR("<--xgbe_init_function_ptrs\n"); } diff --git a/drivers/net/ethernet/amd/xgbe/xgbe-drv.c b/drivers/net/ethernet/amd/xgbe/xgbe-drv.c index f249f89fec38..51b4adb8a404 100755 --- a/drivers/net/ethernet/amd/xgbe/xgbe-drv.c +++ b/drivers/net/ethernet/amd/xgbe/xgbe-drv.c @@ -2290,10 +2290,17 @@ static int xgbe_set_features(struct net_device *netdev, if (ret) return ret; - if ((features & NETIF_F_RXCSUM) && !rxcsum) + if ((features & NETIF_F_RXCSUM) && !rxcsum) { + hw_if->enable_sph(pdata); + hw_if->enable_vxlan(pdata); hw_if->enable_rx_csum(pdata); - else if (!(features & NETIF_F_RXCSUM) && rxcsum) + schedule_work(&pdata->restart_work); + } else if (!(features & NETIF_F_RXCSUM) && rxcsum) { + hw_if->disable_sph(pdata); + hw_if->disable_vxlan(pdata); hw_if->disable_rx_csum(pdata); + schedule_work(&pdata->restart_work); + } if ((features & NETIF_F_HW_VLAN_CTAG_RX) && !rxvlan) hw_if->enable_rx_vlan_stripping(pdata); diff --git a/drivers/net/ethernet/amd/xgbe/xgbe.h b/drivers/net/ethernet/amd/xgbe/xgbe.h index db73c8f8b139..92b61a318f66 100755 --- a/drivers/net/ethernet/amd/xgbe/xgbe.h +++ b/drivers/net/ethernet/amd/xgbe/xgbe.h @@ -902,6 +902,10 @@ struct xgbe_hw_if { void (*enable_vxlan)(struct xgbe_prv_data *); void (*disable_vxlan)(struct xgbe_prv_data *); void (*set_vxlan_id)(struct xgbe_prv_data *); + + /* For Split Header */ + void (*enable_sph)(struct xgbe_prv_data *pdata); + void (*disable_sph)(struct xgbe_prv_data *pdata); }; /* This structure represents implementation specific routines for an -- 2.34.1

[PATCH v2] Input: cyttsp5 - fix power control issue on wakeup

by Hugo Villeneuve

From: Mikael Gonella-Bolduc <mgonellabolduc(a)dimonoff.com> The power control function ignores the "on" argument when setting the report ID, and thus is always sending HID_POWER_SLEEP. This causes a problem when trying to wakeup. Fix by sending the state variable, which contains the proper HID_POWER_ON or HID_POWER_SLEEP based on the "on" argument.

Only reason to disable interrupts during bus resume would be to prevent the interrupt handler from interfering with the resume process of USB 2 ports. Host initiated resume of USB 2 ports is done in two stages. The xhci driver first transitions the port from 'U3' to 'Resume' state, then wait in Resume for 20ms, and finally moves port to U0 state. xhci driver can't prevent interrupts by keeping the xhci spinlock due to this 20ms sleep. Limit interrupt disabling to the USB 2 port resume case only. resuming USB 2 ports in bus resume is only done in special cases where USB 2 ports had to be forced to suspend during bus suspend. The current way of preventing interrupts by clearing the 'Interrupt Enable' (INTE) bit in USBCMD register won't prevent the Interrupter registers 'Interrupt Pending' (IP), 'Event Handler Busy' (EHB) and USBSTS register Event Interrupt (EINT) bits from being set.

Only reason to disable interrupts during bus resume would be to prevent the interrupt handler from interfering with the resume process of USB 2 ports. Host initiated resume of USB 2 ports is done in two stages. The xhci driver first transitions the port from 'U3' to 'Resume' state, then wait in Resume for 20ms, and finally moves port to U0 state. xhci driver can't prevent interrupts by keeping the xhci spinlock due to this 20ms sleep. Limit interrupt disabling to the USB 2 port resume case only. resuming USB 2 ports in bus resume is only done in special cases where USB 2 ports had to be forced to suspend during bus suspend. The current way of preventing interrupts by clearing the 'Interrupt Enable' (INTE) bit in USBCMD register won't prevent the Interrupter registers 'Interrupt Pending' (IP), 'Event Handler Busy' (EHB) and USBSTS register Event Interrupt (EINT) bits from being set. New interrupts can't be issued before those bits are properly clered. Disable interrupts by clearing the interrupter register 'Interrupt Enable' (IE) bit instead. This way IP, EHB and INTE won't be set before IE is enabled again and a new interrupt is triggered.

Failing to check for NULL may lead to a NULL pointer dereference if the result is used later in processing, potentially causing crashes, data corruption, or undefined behavior. On XDP redirect failure, the associated page must be released explicitly if it was previously retained via get_page(). Failing to do so may result in a memory leak, as the pages reference count is not decremented.

GCC 15 and stable kernels

by Chris Clayton

Hi Greg, I've built the four stable kernels that were released on 25 April. I found that to successfully build with GCC-15, each of them required backports of one or both of two upstream commits. Those commits are: Title Commit Author nonstring 9d7a0577c9db35c4cc52db90bc415ea248446472 Linus gnu11 b3bee1e7c3f2b1b77182302c7b2131c804175870 Alexey Dobriyan 6.14.4 and 6.12.25 required only nonstring. 6.6.87 required only gnu11, 6.1.35 required both. Additionally, chasing down why my new Bluetooth mouse doesn't work, I also had cause to build 5.15.180 and found that it needed gnull. I have TO dash out now, but I could send you a zip archive of the patches later today, if that would help. Chris

Re: FW: Wireless speed regression issue with >6.12.12/6.13.x + firmware update for mediatek MT7925

by Mingyen Hsieh (謝明諺)

Hi, Thanks for reporting this issue. We will conduct testing again. And it is already known that the patch added in 6.12.13 does have some issues, but we have also submitted new patches to fix. Currently, these patches are in the maintainer’s tree. It should soon be included in 6.14 and then ported Back to 6.12.x and 6.13.x. Perhaps you can test the driver from here: https://github.com/nbd168/wireless and apply this patch: https://patchwork.kernel.org/project/linux-wireless/patch/20250317011724.33… Thanks Best Regards, Yen.

[PATCH 6.6.y] x86/pvh: Call C code via the kernel virtual mapping

by Jason Andryuk

From: Ard Biesheuvel <ardb(a)kernel.org> [ Upstream commit e8fbc0d9cab6c1ee6403f42c0991b0c1d5dbc092 ] Calling C code via a different mapping than it was linked at is problematic, because the compiler assumes that RIP-relative and absolute symbol references are interchangeable. GCC in particular may use RIP-relative per-CPU variable references even when not using -fpic. So call xen_prepare_pvh() via its kernel virtual mapping on x86_64, so that those RIP-relative references produce the correct values. This matches the pre-existing behavior for i386, which also invokes xen_prepare_pvh() via the kernel virtual mapping before invoking startup_32 with paging disabled again. Fixes: 7243b93345f7 ("xen/pvh: Bootstrap PVH guest") Tested-by: Jason Andryuk <jason.andryuk(a)amd.com> Reviewed-by: Jason Andryuk <jason.andryuk(a)amd.com> Signed-off-by: Ard Biesheuvel <ardb(a)kernel.org> Message-ID: <20241009160438.3884381-8-ardb+git(a)google.com> Signed-off-by: Juergen Gross <jgross(a)suse.com> [ Stable context update ] Signed-off-by: Jason Andryuk <jason.andryuk(a)amd.com> --- Stable backport for 6.6. This was added to 6.1, 5.15, and 5.10, but it is also needed for 6.6. Direct cherry-pick needed context fixups, which are made here. This upstream commit was previously included in stable, but with the pre-req of b464b461d27d ("x86/pvh: Set phys_base when calling xen_prepare_pvh()"). Both were subsequently reverted as b464b461d27d caused regressions. This backport, e8fbc0d9cab6, in isolation is correct. This fixes a regression introduced by the backport of upstream commit b4845bb6383821a9516ce30af3a27dc873e37fd4 ("x86/xen: add central hypercall functions") b4845bb63838 adds a comparison between rip-relative xen_hypercall_amd() and kernel virtual address of xen_hypercall_amd() to determine whether to use the AMD or Intel variant. When running from the identity mapped address, the comparison always fail. The leads to calling xen_hypercall_intel(), even on AMD processors, which faults and halts boot. This affects PVH dom0 - domU doesn't seem to be affected. This patch performs the rip-relative mapping from the kernel virtual mapping, so the values can be properly compared. --- arch/x86/platform/pvh/head.S | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/arch/x86/platform/pvh/head.S b/arch/x86/platform/pvh/head.S index c4365a05ab83..fc46b4dfbd74 100644 --- a/arch/x86/platform/pvh/head.S +++ b/arch/x86/platform/pvh/head.S @@ -100,7 +100,12 @@ SYM_CODE_START_LOCAL(pvh_start_xen) xor %edx, %edx wrmsr - call xen_prepare_pvh + /* Call xen_prepare_pvh() via the kernel virtual mapping */ + leaq xen_prepare_pvh(%rip), %rax + subq phys_base(%rip), %rax + addq $__START_KERNEL_map, %rax + ANNOTATE_RETPOLINE_SAFE + call *%rax /* startup_64 expects boot_params in %rsi. */ mov $_pa(pvh_bootparams), %rsi -- 2.49.0

[PATCH 26/28] drm/amd/display: Fix wrong handling for AUX_DEFER case

by Ray Wu

From: Wayne Lin <Wayne.Lin(a)amd.com> [Why] We incorrectly ack all bytes get written when the reply actually is defer. When it's defer, means sink is not ready for the request.

[PATCH v2 1/2] usb: typec: ucsi: displayport: Fix deadlock

by Andrei Kuchynski

This patch introduces the ucsi_con_mutex_lock / ucsi_con_mutex_unlock functions to the UCSI driver. ucsi_con_mutex_lock ensures the connector mutex is only locked if a connection is established and the partner pointer is valid. This resolves a deadlock scenario where ucsi_displayport_remove_partner holds con->mutex waiting for dp_altmode_work to complete while dp_altmode_work attempts to acquire it.

When one process do a report zones and another process freezes the block device, the report zones side cannot allocate a tag because the freeze is already started. This can thus result in new block group creation to hang forever, blocking the write path. Thankfully, a new block group should be created on empty zones. So, reporting the zones is not necessary and we can set the write pointer = 0 and load the zone capacity from the block layer using bdev_zone_capacity() helper. ====================================================== WARNING: possible circular locking dependency detected 6.14.0-rc1 #252 Not tainted ------------------------------------------------------ modprobe/1110 is trying to acquire lock: ffff888100ac83e0 ((work_completion)(&(&wb->dwork)->work)){+.+.}-{0:0}, at: __flush_work+0x38f/0xb60 but task is already holding lock: ffff8881205b6f20 (&q->q_usage_counter(queue)#16){++++}-{0:0}, at: sd_remove+0x85/0x130 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #3 (&q->q_usage_counter(queue)#16){++++}-{0:0}: blk_queue_enter+0x3d9/0x500 blk_mq_alloc_request+0x47d/0x8e0 scsi_execute_cmd+0x14f/0xb80 sd_zbc_do_report_zones+0x1c1/0x470 sd_zbc_report_zones+0x362/0xd60 blkdev_report_zones+0x1b1/0x2e0 btrfs_get_dev_zones+0x215/0x7e0 [btrfs] btrfs_load_block_group_zone_info+0x6d2/0x2c10 [btrfs] btrfs_make_block_group+0x36b/0x870 [btrfs] btrfs_create_chunk+0x147d/0x2320 [btrfs] btrfs_chunk_alloc+0x2ce/0xcf0 [btrfs] start_transaction+0xce6/0x1620 [btrfs] btrfs_uuid_scan_kthread+0x4ee/0x5b0 [btrfs] kthread+0x39d/0x750 ret_from_fork+0x30/0x70 ret_from_fork_asm+0x1a/0x30 -> #2 (&fs_info->dev_replace.rwsem){++++}-{4:4}: down_read+0x9b/0x470 btrfs_map_block+0x2ce/0x2ce0 [btrfs] btrfs_submit_chunk+0x2d4/0x16c0 [btrfs] btrfs_submit_bbio+0x16/0x30 [btrfs] btree_write_cache_pages+0xb5a/0xf90 [btrfs] do_writepages+0x17f/0x7b0 __writeback_single_inode+0x114/0xb00 writeback_sb_inodes+0x52b/0xe00 wb_writeback+0x1a7/0x800 wb_workfn+0x12a/0xbd0 process_one_work+0x85a/0x1460 worker_thread+0x5e2/0xfc0 kthread+0x39d/0x750 ret_from_fork+0x30/0x70 ret_from_fork_asm+0x1a/0x30 -> #1 (&fs_info->zoned_meta_io_lock){+.+.}-{4:4}: __mutex_lock+0x1aa/0x1360 btree_write_cache_pages+0x252/0xf90 [btrfs] do_writepages+0x17f/0x7b0 __writeback_single_inode+0x114/0xb00 writeback_sb_inodes+0x52b/0xe00 wb_writeback+0x1a7/0x800 wb_workfn+0x12a/0xbd0 process_one_work+0x85a/0x1460 worker_thread+0x5e2/0xfc0 kthread+0x39d/0x750 ret_from_fork+0x30/0x70 ret_from_fork_asm+0x1a/0x30 -> #0 ((work_completion)(&(&wb->dwork)->work)){+.+.}-{0:0}: __lock_acquire+0x2f52/0x5ea0 lock_acquire+0x1b1/0x540 __flush_work+0x3ac/0xb60 wb_shutdown+0x15b/0x1f0 bdi_unregister+0x172/0x5b0 del_gendisk+0x841/0xa20 sd_remove+0x85/0x130 device_release_driver_internal+0x368/0x520 bus_remove_device+0x1f1/0x3f0 device_del+0x3bd/0x9c0 __scsi_remove_device+0x272/0x340 scsi_forget_host+0xf7/0x170 scsi_remove_host+0xd2/0x2a0 sdebug_driver_remove+0x52/0x2f0 [scsi_debug] device_release_driver_internal+0x368/0x520 bus_remove_device+0x1f1/0x3f0 device_del+0x3bd/0x9c0 device_unregister+0x13/0xa0 sdebug_do_remove_host+0x1fb/0x290 [scsi_debug] scsi_debug_exit+0x17/0x70 [scsi_debug] __do_sys_delete_module.isra.0+0x321/0x520 do_syscall_64+0x93/0x180 entry_SYSCALL_64_after_hwframe+0x76/0x7e other info that might help us debug this: Chain exists of: (work_completion)(&(&wb->dwork)->work) --> &fs_info->dev_replace.rwsem --> &q->q_usage_counter(queue)#16 Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&q->q_usage_counter(queue)#16); lock(&fs_info->dev_replace.rwsem); lock(&q->q_usage_counter(queue)#16); lock((work_completion)(&(&wb->dwork)->work)); *** DEADLOCK *** 5 locks held by modprobe/1110: #0: ffff88811f7bc108 (&dev->mutex){....}-{4:4}, at: device_release_driver_internal+0x8f/0x520 #1: ffff8881022ee0e0 (&shost->scan_mutex){+.+.}-{4:4}, at: scsi_remove_host+0x20/0x2a0 #2: ffff88811b4c4378 (&dev->mutex){....}-{4:4}, at: device_release_driver_internal+0x8f/0x520 #3: ffff8881205b6f20 (&q->q_usage_counter(queue)#16){++++}-{0:0}, at: sd_remove+0x85/0x130 #4: ffffffffa3284360 (rcu_read_lock){....}-{1:3}, at: __flush_work+0xda/0xb60 stack backtrace: CPU: 0 UID: 0 PID: 1110 Comm: modprobe Not tainted 6.14.0-rc1 #252 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-3.fc41 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x6a/0x90 print_circular_bug.cold+0x1e0/0x274 check_noncircular+0x306/0x3f0 ?

But, the call back is wrongly marked as __init, causing it to be freed, while being registered with the PCI subsystem and could trigger: Unable to handle kernel paging request at virtual address ffff8000816c0400 gicv2m_get_fwnode+0x0/0x58 (P) pci_set_bus_msi_domain+0x74/0x88 pci_register_host_bridge+0x194/0x548 This is easily reproducible on a Juno board with ACPI boot.
