[tip: timers/urgent] clocksource/i8253: Use raw_spinlock_irqsave() in clockevent_i8253_disable()

If some of the old i8253 hardware is actually used then lockdep will notice that i8253_lock is used in hard interrupt context. This causes lockdep to complain because it observed the lock being acquired with interrupts enabled and in hard interrupt context. Make clockevent_i8253_disable() acquire the lock with raw_spinlock_irqsave() to cure this.

[PATCH 2/2] xhci: dbc: Avoid event polling busyloop if pending rx transfers are inactive.

by Mathias Nyman

Event polling delay is set to 0 if there are any pending requests in either rx or tx requests lists. Checking for pending requests does not work well for "IN" transfers as the tty driver always queues requests to the list and TRBs to the ring, preparing to receive data from the host. This causes unnecessary busylooping and cpu hogging. Only set the event polling delay to 0 if there are pending tx "write" transfers, or if it was less than 10ms since last active data transfer in any direction.

[PATCH v2 rc] iommu: Skip PASID validation for devices without PASID capability

by Tushar Dave

Generally PASID support requires ACS settings that usually create single device groups, but there are some niche cases where we can get multi-device groups and still have working PASID support. The primary issue is that PCI switches are not required to treat PASID tagged TLPs specially so appropriate ACS settings are required to route all TLPs to the host bridge if PASID is going to work properly. pci_enable_pasid() does check that each device that will use PASID has the proper ACS settings to achieve this routing. However, no-PASID devices can be combined with PASID capable devices within the same topology using non-uniform ACS settings. In this case the no-PASID devices may not have strict route to host ACS flags and end up being grouped with the PASID devices. This configuration fails to allow use of the PASID within the iommu core code which wrongly checks if the no-PASID device supports PASID. Fix this by ignoring no-PASID devices during the PASID validation. They will never issue a PASID TLP anyhow so they can be ignored.

[PATCH] xfs: fix diff_two_keys calculation for cnt btree

by Fedor Pchelkin

Currently the difference is computed on 32-bit unsigned values although eventually it is stored in a variable of int64_t type. This gives awkward results, e.g. when the diff _should_ be negative, it is represented as some large positive int64_t value. Perform the calculations directly in int64_t as all other diff_two_keys routines actually do. Found by Linux Verification Center (linuxtesting.org) with Svace static analysis tool.

These patchset adds support for VPU_JSM_STATUS_MVNCI_CONTEXT_VIOLATION_HW message added in recent VPU firmware. Without it the driver will not be able to process any jobs after this message is received and would need to be reloaded. Most patches are as-is from upstream besides these two: - Fix locking order in ivpu_job_submit - Abort all jobs after command queue unregister Both these patches need to be rebased because of missing new CMDQ UAPI changes that should not be backported to stable. Andrew Kreimer (1): accel/ivpu: Fix a typo Andrzej Kacprowski (1): accel/ivpu: Update VPU FW API headers Karol Wachowski (4): accel/ivpu: Use xa_alloc_cyclic() instead of custom function accel/ivpu: Abort all jobs after command queue unregister accel/ivpu: Fix locking order in ivpu_job_submit accel/ivpu: Add handling of VPU_JSM_STATUS_MVNCI_CONTEXT_VIOLATION_HW Tomasz Rusinowicz (1): accel/ivpu: Make DB_ID and JOB_ID allocations incremental drivers/accel/ivpu/ivpu_drv.c | 38 ++-- drivers/accel/ivpu/ivpu_drv.h | 9 + drivers/accel/ivpu/ivpu_job.c | 125 +++++++++--- drivers/accel/ivpu/ivpu_job.h | 1 + drivers/accel/ivpu/ivpu_jsm_msg.c | 3 +- drivers/accel/ivpu/ivpu_mmu.c | 3 +- drivers/accel/ivpu/ivpu_sysfs.c | 5 +- drivers/accel/ivpu/vpu_boot_api.h | 45 +++-- drivers/accel/ivpu/vpu_jsm_api.h | 303 +++++++++++++++++++++++++----- 9 files changed, 412 insertions(+), 120 deletions(-) -- 2.45.1

[PATCH v2 0/3] accel/ivpu: Add context violation handling for 6.14

by Jacek Lawrynowicz

These patchset adds support for VPU_JSM_STATUS_MVNCI_CONTEXT_VIOLATION_HW message added in recent VPU firmware. Without it the driver will not be able to process any jobs after this message is received and would need to be reloaded. The last patch in this series is as-is from upstream, but other two patches had to be rebased because of missing new CMDQ UAPI changes that should not be backported to stable. Changes since v1: - Documented deviations from the original upstream patches in commit messages Karol Wachowski (3): accel/ivpu: Abort all jobs after command queue unregister accel/ivpu: Fix locking order in ivpu_job_submit accel/ivpu: Add handling of VPU_JSM_STATUS_MVNCI_CONTEXT_VIOLATION_HW drivers/accel/ivpu/ivpu_drv.c | 32 ++------- drivers/accel/ivpu/ivpu_drv.h | 2 + drivers/accel/ivpu/ivpu_job.c | 111 ++++++++++++++++++++++++++------ drivers/accel/ivpu/ivpu_job.h | 1 + drivers/accel/ivpu/ivpu_mmu.c | 3 +- drivers/accel/ivpu/ivpu_sysfs.c | 5 +- 6 files changed, 103 insertions(+), 51 deletions(-) -- 2.45.1

[PATCH] fs: minix: Fix handling of corrupted directories

by Andrey Kriulin

If the directory is corrupted and the number of nlinks is less than 2 (valid nlinks have at least 2), then when the directory is deleted, the minix_rmdir will try to reduce the nlinks(unsigned int) to a negative value. Make nlinks validity check for directory in minix_lookup. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

[PATCH 0/3] can: rx-offload: fix order of unregistration calls

by Marc Kleine-Budde

If a driver is removed, the driver framework invokes the driver's remove callback. A CAN driver's remove function calls unregister_candev(), which calls net_device_ops::ndo_stop further down in the call stack for interfaces which are in the "up" state. With the mcp251xfd driver the removal of the module causes the following warning: | WARNING: CPU: 0 PID: 352 at net/core/dev.c:7342 __netif_napi_del_locked+0xc8/0xd8 as can_rx_offload_del() deletes the NAPI, while it is still active, because the interface is still up. To fix the warning, first unregister the network interface, which calls net_device_ops::ndo_stop, which disables the NAPI, and then call can_rx_offload_del(). All other driver using the rx-offload helper have been checked and the same issue has been found in the rockchip and m_can driver. These have been fixed, but only compile time tested. On the mcp251xfd the fix was tested on hardware.

When using a USB-C dock, and the dock is unplugged, the corresponding amdgpu_dm_connector objects are freed, creating dangling pointers in the HDCP code. When the dock is plugged back, the dangling pointers are dereferenced, resulting in a slab-use-after-free: [ 66.775837] BUG: KASAN: slab-use-after-free in event_property_validate+0x42f/0x6c0 [amdgpu] [ 66.776171] Read of size 4 at addr ffff888127804120 by task kworker/0:1/10 [ 66.776179] CPU: 0 UID: 0 PID: 10 Comm: kworker/0:1 Not tainted 6.14.0-rc7-00180-g54505f727a38-dirty #233 [ 66.776183] Hardware name: HP HP Pavilion Aero Laptop 13-be0xxx/8916, BIOS F.17 12/18/2024 [ 66.776186] Workqueue: events event_property_validate [amdgpu] [ 66.776494] Call Trace: [ 66.776496] <TASK> [ 66.776497] dump_stack_lvl+0x70/0xa0 [ 66.776504] print_report+0x175/0x555 [ 66.776507] ? __virt_addr_valid+0x243/0x450 [ 66.776510] ? kasan_complete_mode_report_info+0x66/0x1c0 [ 66.776515] kasan_report+0xeb/0x1c0 [ 66.776518] ? event_property_validate+0x42f/0x6c0 [amdgpu] [ 66.776819] ? event_property_validate+0x42f/0x6c0 [amdgpu] [ 66.777121] __asan_report_load4_noabort+0x14/0x20 [ 66.777124] event_property_validate+0x42f/0x6c0 [amdgpu] [ 66.777342] ? __lock_acquire+0x6b40/0x6b40 [ 66.777347] ? enable_assr+0x250/0x250 [amdgpu] [ 66.777571] process_one_work+0x86b/0x1510 [ 66.777575] ? pwq_dec_nr_in_flight+0xcf0/0xcf0 [ 66.777578] ? assign_work+0x16b/0x280 [ 66.777580] ? lock_is_held_type+0xa3/0x130 [ 66.777583] worker_thread+0x5c0/0xfa0 [ 66.777587] ? process_one_work+0x1510/0x1510 [ 66.777588] kthread+0x3a2/0x840 [ 66.777591] ? kthread_is_per_cpu+0xd0/0xd0 [ 66.777594] ? trace_hardirqs_on+0x4f/0x60 [ 66.777597] ? _raw_spin_unlock_irq+0x27/0x60 [ 66.777599] ? calculate_sigpending+0x77/0xa0 [ 66.777602] ? kthread_is_per_cpu+0xd0/0xd0 [ 66.777605] ret_from_fork+0x40/0x90 [ 66.777607] ? kthread_is_per_cpu+0xd0/0xd0 [ 66.777609] ret_from_fork_asm+0x11/0x20 [ 66.777614] </TASK> [ 66.777643] Allocated by task 10: [ 66.777646] kasan_save_stack+0x39/0x60 [ 66.777649] kasan_save_track+0x14/0x40 [ 66.777652] kasan_save_alloc_info+0x37/0x50 [ 66.777655] __kasan_kmalloc+0xbb/0xc0 [ 66.777658] __kmalloc_cache_noprof+0x1c8/0x4b0 [ 66.777661] dm_dp_add_mst_connector+0xdd/0x5c0 [amdgpu] [ 66.777880] drm_dp_mst_port_add_connector+0x47e/0x770 [drm_display_helper] [ 66.777892] drm_dp_send_link_address+0x1554/0x2bf0 [drm_display_helper] [ 66.777901] drm_dp_check_and_send_link_address+0x187/0x1f0 [drm_display_helper] [ 66.777909] drm_dp_mst_link_probe_work+0x2b8/0x410 [drm_display_helper] [ 66.777917] process_one_work+0x86b/0x1510 [ 66.777919] worker_thread+0x5c0/0xfa0 [ 66.777922] kthread+0x3a2/0x840 [ 66.777925] ret_from_fork+0x40/0x90 [ 66.777927] ret_from_fork_asm+0x11/0x20 [ 66.777932] Freed by task 1713: [ 66.777935] kasan_save_stack+0x39/0x60 [ 66.777938] kasan_save_track+0x14/0x40 [ 66.777940] kasan_save_free_info+0x3b/0x60 [ 66.777944] __kasan_slab_free+0x52/0x70 [ 66.777946] kfree+0x13f/0x4b0 [ 66.777949] dm_dp_mst_connector_destroy+0xfa/0x150 [amdgpu] [ 66.778179] drm_connector_free+0x7d/0xb0 [ 66.778184] drm_mode_object_put.part.0+0xee/0x160 [ 66.778188] drm_mode_object_put+0x37/0x50 [ 66.778191] drm_atomic_state_default_clear+0x220/0xd60 [ 66.778194] __drm_atomic_state_free+0x16e/0x2a0 [ 66.778197] drm_mode_atomic_ioctl+0x15ed/0x2ba0 [ 66.778200] drm_ioctl_kernel+0x17a/0x310 [ 66.778203] drm_ioctl+0x584/0xd10 [ 66.778206] amdgpu_drm_ioctl+0xd2/0x1c0 [amdgpu] [ 66.778375] __x64_sys_ioctl+0x139/0x1a0 [ 66.778378] x64_sys_call+0xee7/0xfb0 [ 66.778381] do_syscall_64+0x87/0x140 [ 66.778385] entry_SYSCALL_64_after_hwframe+0x4b/0x53 Fix this by properly incrementing and decrementing the reference counts when making and deleting copies of the amdgpu_dm_connector pointers.

Device 4028 The IORT logic populaties two identical IDs into the fwspec->ids array via DMA aliasing in iort_pci_iommu_init() called by pci_for_each_dma_alias(). Though the SMMU driver had been able to handle this situation since commit 563b5cbe334e ("iommu/arm-smmu-v3: Cope with duplicated Stream IDs"), that got broken by the later commit cdf315f907d4 ("iommu/arm-smmu-v3: Maintain a SID->device structure"), which ended up with allocating separate streams with the same stuffing.

Note: this has been failing the iommu_device_probe() since 2021, although a recent iommu commit in v6.15-rc1 that moves iommu_device_probe() started to fail the SMMU driver probe. Since nobody has cared about DMA Alias support, leave that as it was but fix the fundamental iommu_device_probe() breakage.

Comparing ACPIID_LEN against a total string length doesn't take into account the lengths of individual hid and uid buffers so the check is insufficient in some cases. For example if the length of hid string is 4 and the length of the uid string is 260, the length of str will be equal to ACPIID_LEN + 1 but uid string will overflow uid buffer which size is 256. The same applies to the hid string with length 13 and uid string with length 250. Check the length of hid and uid strings separately to prevent buffer overflow.

This turned out to be because we were not writing out dirty blocks sometimes, so this in fact affects all metadata writes. When writing out a subpage EB we scan the subpage bitmap for a dirty range. If the range isn't dirty we do bit_start++; to move onto the next bit. The problem is the bitmap is based on the number of sectors that an EB has. So in this case, we have a 64k pagesize, 16k nodesize, but a 4k sectorsize. This means our bitmap is 4 bits for every node. With a 64k page size we end up with 4 nodes per page. To make this easier this is how everything looks [0 16k 32k 48k ] logical address [0 4 8 12 ] radix tree offset [ 64k page ] folio [ 16k eb ][ 16k eb ][ 16k eb ][ 16k eb ] extent buffers [ | | | | | | | | | | | | | | | | ] bitmap Now we use all of our addressing based on fs_info->sectorsize_bits, so as you can see the above our 16k eb->start turns into radix entry 4. When we find a dirty range for our eb, we correctly do bit_start += sectors_per_node, because if we start at bit 0, the next bit for the next eb is 4, to correspond to eb->start 16k. However if our range is clean, we will do bit_start++, which will now put us offset from our radix tree entries. In our case, assume that the first time we check the bitmap the block is not dirty, we increment bit_start so now it == 1, and then we loop around and check again. This time it is dirty, and we go to find that start using the following equation start = folio_start + bit_start * fs_info->sectorsize; so in the case above, eb->start 0 is now dirty, and we calculate start as 0 + 1 * fs_info->sectorsize = 4096 4096 >> 12 = 1 Now we're looking up the radix tree for 1, and we won't find an eb. What's worse is now we're using bit_start == 1, so we do bit_start += sectors_per_node, which is now 5. If that eb is dirty we will run into the same thing, we will look at an offset that is not populated in the radix tree, and now we're skipping the writeout of dirty extent buffers. The best fix for this is to not use sectorsize_bits to address nodes, but that's a larger change. Since this is a fs corruption problem fix it simply by always using sectors_per_node to increment the start bit.

[PATCH 0/3] accel/ivpu: Add context violation handling for 6.14

by Jacek Lawrynowicz

These patchset adds support for VPU_JSM_STATUS_MVNCI_CONTEXT_VIOLATION_HW message added in recent VPU firmware. Without it the driver will not be able to process any jobs after this message is received and would need to be reloaded. The last patch in this series is as-is from upstream, but other two patches had to be rebased because of missing new CMDQ UAPI changes that should not be backported to stable.

[PATCH v4.1] x86/sev: Fix making shared pages private during kdump

by Ashish Kalra

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. The check for handling the case of GHCB contained within a huge page incorrectly skips a page just below the GHCB page from being transitioned back to private during kdump preparation. This skipped page causes a 0x404 #VC exception when it is accessed later while dumping guest memory during vmcore generation via kdump. Correct the range to be checked for GHCB contained in a huge page. Also ensure that the skipped huge page containing the GHCB page is transitioned back to private by applying the correct address mask later when changing GHCBs to private at end of kdump preparation.

[PATCH v2 0/1] mm: Xen PV regression after THP PTE optimization

Hi all, I recently discovered an mm regression introduced in kernel version 6.9 that affects systems running as a Xen PV domain [1]. Original fix proposal wasn't ideal, but it sparked a discussion which helped us fully understand the root cause. The new v2 patch contains changes based on David Hildenbrand's proposal to cap max_nr to the number of PFNs that actually remain in the folio and to clean up the loop.

[PATCH] x86/boot/sev: Support memory acceptance in the EFI stub under SVSM

by Ard Biesheuvel

From: Ard Biesheuvel <ardb(a)kernel.org> Commit d54d610243a4 ("x86/boot/sev: Avoid shared GHCB page for early memory acceptance") provided a fix for SEV-SNP memory acceptance from the EFI stub when running at VMPL #0. However, that fix was insufficient for SVSM SEV-SNP guests running at VMPL >0, as those rely on a SVSM calling area, which is a shared buffer whose address is programmed into a SEV-SNP MSR, and the SEV init code that sets up this calling area executes much later during the boot. Given that booting via the EFI stub at VMPL >0 implies that the firmware has configured this calling area already, reuse it for performing memory acceptance in the EFI stub.

arch_bpf_trampoline_size() provides JIT size of the BPF trampoline before the buffer for JIT'ing it is allocated. The total number of instructions emitted for BPF trampoline JIT code depends on where the final image is located. So, the size arrived at with the dummy pass in arch_bpf_trampoline_size() can vary from the actual size needed in arch_prepare_bpf_trampoline(). When the instructions accounted in arch_bpf_trampoline_size() is less than the number of instructions emitted during the actual JIT compile of the trampoline, the below warning is produced: WARNING: CPU: 8 PID: 204190 at arch/powerpc/net/bpf_jit_comp.c:981 __arch_prepare_bpf_trampoline.isra.0+0xd2c/0xdcc which is: /* Make sure the trampoline generation logic doesn't overflow */ if (image && WARN_ON_ONCE(&image[ctx->idx] > (u32 *)rw_image_end - BPF_INSN_SAFETY)) { So, during the dummy pass, instead of providing some arbitrary image location, account for maximum possible instructions if and when there is a dependency with image location for JIT'ing.

+ mm-fix-folio_pte_batch-on-xen-pv.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: mm: fix folio_pte_batch() on XEN PV has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-fix-folio_pte_batch-on-xen-pv.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: Petr Van��k <arkamar(a)atlas.cz> Subject: mm: fix folio_pte_batch() on XEN PV Date: Fri, 2 May 2025 23:50:19 +0200 On XEN PV, folio_pte_batch() can incorrectly batch beyond the end of a folio due to a corner case in pte_advance_pfn(). Specifically, when the PFN following the folio maps to an invalidated MFN, expected_pte = pte_advance_pfn(expected_pte, nr); produces a pte_none(). If the actual next PTE in memory is also pte_none(), the pte_same() succeeds, if (!pte_same(pte, expected_pte)) break; the loop is not broken, and batching continues into unrelated memory. For example, with a 4-page folio, the PTE layout might look like this: [ 53.465673] [ T2552] folio_pte_batch: printing PTE values at addr=0x7f1ac9dc5000 [ 53.465674] [ T2552] PTE[453] = 000000010085c125 [ 53.465679] [ T2552] PTE[454] = 000000010085d125 [ 53.465682] [ T2552] PTE[455] = 000000010085e125 [ 53.465684] [ T2552] PTE[456] = 000000010085f125 [ 53.465686] [ T2552] PTE[457] = 0000000000000000 <-- not present [ 53.465689] [ T2552] PTE[458] = 0000000101da7125 pte_advance_pfn(PTE[456]) returns a pte_none() due to invalid PFN->MFN mapping. The next actual PTE (PTE[457]) is also pte_none(), so the loop continues and includes PTE[457] in the batch, resulting in 5 batched entries for a 4-page folio. This triggers the following warning: [ 53.465751] [ T2552] page: refcount:85 mapcount:20 mapping:ffff88813ff4f6a8 index:0x110 pfn:0x10085c [ 53.465754] [ T2552] head: order:2 mapcount:80 entire_mapcount:0 nr_pages_mapped:4 pincount:0 [ 53.465756] [ T2552] memcg:ffff888003573000 [ 53.465758] [ T2552] aops:0xffffffff8226fd20 ino:82467c dentry name(?):"libc.so.6" [ 53.465761] [ T2552] flags: 0x2000000000416c(referenced|uptodate|lru|active|private|head|node=0|zone=2) [ 53.465764] [ T2552] raw: 002000000000416c ffffea0004021f08 ffffea0004021908 ffff88813ff4f6a8 [ 53.465767] [ T2552] raw: 0000000000000110 ffff888133d8bd40 0000005500000013 ffff888003573000 [ 53.465768] [ T2552] head: 002000000000416c ffffea0004021f08 ffffea0004021908 ffff88813ff4f6a8 [ 53.465770] [ T2552] head: 0000000000000110 ffff888133d8bd40 0000005500000013 ffff888003573000 [ 53.465772] [ T2552] head: 0020000000000202 ffffea0004021701 000000040000004f 00000000ffffffff [ 53.465774] [ T2552] head: 0000000300000003 8000000300000002 0000000000000013 0000000000000004 [ 53.465775] [ T2552] 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) Original code works as expected everywhere, except on XEN PV, where pte_advance_pfn() can yield a pte_none() after balloon inflation due to MFNs invalidation. In XEN, pte_advance_pfn() ends up calling __pte()->xen_make_pte()->pte_pfn_to_mfn(), which returns pte_none() when mfn == INVALID_P2M_ENTRY. The pte_pfn_to_mfn() documents that nastiness: If there's no mfn for the pfn, then just create an empty non-present pte. Unfortunately this loses information about the original pfn, so pte_mfn_to_pfn is asymmetric. While such hacks should certainly be removed, we can do better in folio_pte_batch() and simply check ahead of time how many PTEs we can possibly batch in our folio. This way, we can not only fix the issue but cleanup the code: removing the pte_pfn() check inside the loop body and avoiding end_ptr comparison + arithmetic.

[PATCH] arm64/cpufeature: annotate arm64_use_ng_mappings with ro_after_init to prevent wrong idmap generation

[PATCH 6.1 6.6 6.12 6.13] scripts/sorttable: fix ELF64 mcount_loc address parsing when compiling on 32-bit

by Sahil Gupta

The ftrace __mcount_loc buildtime sort does not work properly when the host is 32-bit and the target is 64-bit. sorttable parses the start and stop addresses by calling strtoul on the buffer holding the hexadecimal string. Since the target is 64-bit but unsigned long on 32-bit machines is 32 bits, strtoul, and by extension the start and stop addresses, can max out to 2^32 - 1. This patch adds a new macro, parse_addr, that corresponds to a strtoul or strtoull call based on whether you are operating on a 32-bit ELF or a 64-bit ELF. This way, the correct width is guaranteed whether or not the host is 32-bit. This should cleanly apply on all of the 6.x stable kernels. Manually verified that the __mcount_loc section is sorted by parsing the ELF and verified tests corresponding to CONFIG_FTRACE_SORT_STARTUP_TEST for kernels built on a 32-bit and a 64-bit host.

[PATCH v2] 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] and [2]. 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.

I'm aware that a comprehensive fix will need some adjustments on the DRM sched side, and I plan to address that soon. However, it would be hard to justify the backport of such patches to the stable branches and this issue is affecting users in the moment.

[PATCH v3] x86/sev: Fix making shared pages private during kdump

by Ashish Kalra

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. While handling the case of GHCB page contained within a huge page any shared page just below the GHCB page gets skipped from being transitioned back to private during kdump preparation. This subsequently causes a 0x404 #VC exception when this skipped shared page is accessed later while dumping guest memory during vmcore generation via kdump. Split the initial check for skipping the GHCB page into the page being skipped fully containing the GHCB and GHCB being contained within a huge page. Also ensure that the skipped huge page containing the GHCB page is transitioned back to private later when changing GHCBs to private at end of kdump preparation.

Those GPIOs do not have a corresponding MPM pin and should not be handled inside the MPM driver. The IRQ domain hierarchy is always applied, so it's required to explicitly disconnect the hierarchy for those. The pinctrl-msm driver marks these with GPIO_NO_WAKE_IRQ. qcom-pdc has a check for this, but irq-qcom-mpm is currently missing the check.

[PATCH 4/5] rust: clean Rust 1.88.0's warning about `clippy::disallowed_macros` configuration

by Miguel Ojeda

Starting with Rust 1.88.0 (expected 2025-06-26) [1], Clippy may start warning about paths that do not resolve in the `disallowed_macros` configuration: warning: `kernel::dbg` does not refer to an existing macro --> .clippy.toml:10:5 | 10 | { path = "kernel::dbg", reason = "the `dbg!` macro is intended as a debugging tool" }, | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This is a lint we requested at [2], due to the trouble debugging the lint due to false negatives (e.g. [3]), which we use to emulate `clippy::dbg_macro` [4]. See commit 8577c9dca799 ("rust: replace `clippy::dbg_macro` with `disallowed_macros`") for more details. Given the false negatives are not resolved yet, it is expected that Clippy complains about not finding this macro. Thus, until the false negatives are fixed (and, even then, probably we will need to wait for the MSRV to raise enough), use the escape hatch to allow an invalid path.

[PATCH 3/5] rust: clean Rust 1.88.0's `unnecessary_transmutes` lint

by Miguel Ojeda

Starting with Rust 1.88.0 (expected 2025-06-26) [1][2], `rustc` may introduce a new lint that catches unnecessary transmutes, e.g.: error: unnecessary transmute --> rust/uapi/uapi_generated.rs:23242:18 | 23242 | unsafe { ::core::mem::transmute(self._bitfield_1.get(0usize, 1u8) as u8) } | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: replace this with: `(self._bitfield_1.get(0usize, 1u8) as u8 == 1)` | = note: `-D unnecessary-transmutes` implied by `-D warnings` = help: to override `-D warnings` add `#[allow(unnecessary_transmutes)]` There are a lot of them (at least 300), but luckily they are all in `bindgen`-generated code. Thus clean all up by allowing it there. Since unknown lints trigger a lint itself in older compilers, do it conditionally so that we can keep the `unknown_lints` lint enabled.

[PATCH v4] x86/sev: Don't touch VMSA pages during kdump of SNP guest memory

by Ashish Kalra

From: Ashish Kalra <ashish.kalra(a)amd.com> When kdump is running makedumpfile to generate vmcore and dumping SNP guest memory it touches the VMSA page of the vCPU executing kdump which then results in unrecoverable #NPF/RMP faults as the VMSA page is marked busy/in-use when the vCPU is running and subsequently causes guest softlockup/hang. Additionally other APs may be halted in guest mode and their VMSA pages are marked busy and touching these VMSA pages during guest memory dump will also cause #NPF. Issue AP_DESTROY GHCB calls on other APs to ensure they are kicked out of guest mode and then clear the VMSA bit on their VMSA pages. If the vCPU running kdump is an AP, mark it's VMSA page as offline to ensure that makedumpfile excludes that page while dumping guest memory.

After commit 0a65bc27bd64 ("eventpoll: Set epoll timeout if it's in the future"), the following program would immediately enter a busy loop in the kernel: ``` int main() { int e = epoll_create1(0); struct epoll_event event = {.events = EPOLLIN}; epoll_ctl(e, EPOLL_CTL_ADD, 0, &event); const struct timespec timeout = {.tv_nsec = 1}; epoll_pwait2(e, &event, 1, &timeout, 0); } ``` This happens because the given (non-zero) timeout of 1 nanosecond usually expires before ep_poll() is entered and then ep_schedule_timeout() returns false, but `timed_out` is never set because the code line that sets it is skipped. This quickly turns into a soft lockup, RCU stalls and deadlocks, inflicting severe headaches to the whole system. When the timeout has expired, we don't need to schedule a hrtimer, but we should set the `timed_out` variable. Therefore, I suggest moving the ep_schedule_timeout() check into the `timed_out` expression instead of skipping it.

[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

Linux 6.6.89

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. 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

[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).

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).

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

When sysfs_create_files() fails in wacom_initialize_remotes() the error is returned and the cleanup action will not have been registered yet.

[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] cpufreq: intel_pstate: Unchecked MSR aceess in legacy mode

by Srinivas Pandruvada

When turbo mode is unavailable on a Skylake-X system, executing the command: "echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo" results in an unchecked MSR access error: WRMSR to 0x199 (attempted to write 0x0000000100001300). This issue was reproduced on an OEM (Original Equipment Manufacturer) system and is not a common problem across all Skylake-X systems. This error occurs because the MSR 0x199 Turbo Engage Bit (bit 32) is set when turbo mode is disabled. The issue arises when intel_pstate fails to detect that turbo mode is disabled. Here intel_pstate relies on MSR_IA32_MISC_ENABLE bit 38 to determine the status of turbo mode. However, on this system, bit 38 is not set even when turbo mode is disabled. According to the Intel Software Developer's Manual (SDM), the BIOS sets this bit during platform initialization to enable or disable opportunistic processor performance operations. Logically, this bit should be set in such cases. However, the SDM also specifies that "OS and applications must use CPUID leaf 06H to detect processors with opportunistic processor performance operations enabled." Therefore, in addition to checking MSR_IA32_MISC_ENABLE bit 38, verify that CPUID.06H:EAX[1] is 0 to accurately determine if turbo mode is disabled.

[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

by Ashish Kalra

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. Correct the detection and handling of GHCB pages contained within a huge page.

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.

[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.

possible deadlock in blk_mq_freeze_queue in Linux6.1.25(longterm maintenance, last updated on April 25, 2025)

by Jianzhou Zhao

Hello, I found a potential bug titled " possible deadlock in blk_mq_freeze_queue" with modified syzkaller in the Linux6.12.25(longterm maintenance, last updated on April 25, 2025) If you fix this issue, please add the following tag to the commit: Reported-by: Jianzhou Zhao <luckd0g(a)163.com>, xingwei lee <xrivendell7(a)gmail.com> The commit of the kernel is :

[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.

Commit 29be47fcd6a0 ("nvmem: zynqmp_nvmem: zynqmp_nvmem_probe cleanup") changed the driver to expect the device pointer to be passed as the "context", but in nvmem the context parameter comes from nvmem_config.priv which is never set - Leading to null pointer exceptions when the device is accessed.

[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.

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

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.

[PATCH 5.10.y 1/3] net: dsa: mv88e6xxx: fix atu_move_port_mask for 6341 family

[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.

Call `timer_shutdown_sync()` instead. It does not matter that the timer expiry function pointer is cleared, because the device is being removed.
