Fix two bugs during folio migration if the folio is poisoned. This patch (of 3): Commit 6da6b1d4a7df ("mm/hwpoison: convert TTU_IGNORE_HWPOISON to TTU_HWPOISON") introduce TTU_HWPOISON to replace TTU_IGNORE_HWPOISON in order to stop send SIGBUS signal when accessing an error page after a memory error on a clean folio.

[PATCH 3/3] usb: chipidea: ci_hdrc_imx: implement usb_phy_init() error handling

by Fedor Pchelkin

usb_phy_init() may return an error code if e.g. its implementation fails to prepare/enable some clocks. Detect this early. Trying to disable it later on driver removal would result in a WARNING splat. And properly rollback on probe error path by calling the counterpart usb_phy_shutdown().

This triggers an early boot crash when using syslinux-efi to boot a recent kernel built with CONFIG_X86_5LEVEL=y and CONFIG_EFI_STUB=n, as the 0xff padding that now fills the unused PE/COFF header is copied into boot_params by the bootloader, and interpreted as the top half of the command line pointer. Fix this by sanitizing the boot_params before use.

This triggers an early boot crash when using syslinux-efi to boot a recent kernel built with CONFIG_X86_5LEVEL=y and CONFIG_EFI_STUB=n, as the 0xff padding that now fills the unused PE/COFF header is copied into boot_params by the bootloader, and interpreted as the top half of the command line pointer. Fix this by sanitizing the boot_params before use. Note that there is no harm in calling this more than once; subsequent invocations are able to spot that the boot_params have already been cleaned up.

[PATCH v2 0/6] drm/v3d: Fix GPU reset issues on the Raspberry Pi 5

by Maíra Canal

This series addresses GPU reset issues reported in [1], where running a long compute job would trigger repeated GPU resets, leading to a UI freeze. Patches #1 and #2 prevent the same faulty job from being resubmitted in a loop, mitigating the first cause of the issue. However, the issue isn't entirely solved. Even with only a single GPU reset, the UI still freezes on the Raspberry Pi 5, indicating a GPU hang. Patches #3 to #5 address this by properly configuring the V3D_SMS registers, which are required for power management and resets in V3D 7.1. Patch #6 updates the DT maintainership, replacing Emma with the current v3d driver maintainer.

[REGRESSION] Long boot times due to USB enumeration

by Seïfane Idouchach

Dear all, I am reporting what I believe to be regression due to c0a40097f0bc81deafc15f9195d1fb54595cd6d0. After this change I am experiencing long boot times on a setup that has what seems like a bad usb. The progress of the boot gets halted while retrying (and ultimately failing) to enumerate the USB device and is only allowed to continue after giving up enumerating the USB device. On Arch Linux this manifests itself by a message from SystemD having a wait job on journald. Journald starts just after the enumeration fails with "unable to enumerate USB device". This results in longer boot times on average 1 minute longer than usual (usually around 10s). No stable kernel before this change exhibits the issue all stable kernels after this change exhibit the issue. See the related USB messages attached below (these messages are continuous and have not been snipped) : [...] [ 9.640854] usb 1-9: device descriptor read/64, error -110 [ 25.147505] usb 1-9: device descriptor read/64, error -110 [ 25.650779] usb 1-9: new high-speed USB device number 5 using xhci_hcd [ 30.907482] usb 1-9: device descriptor read/64, error -110 [ 46.480900] usb 1-9: device descriptor read/64, error -110 [ 46.589883] usb usb1-port9: attempt power cycle [ 46.990815] usb 1-9: new high-speed USB device number 6 using xhci_hcd [ 51.791571] usb 1-9: Device not responding to setup address.

[ 67.154086] usb 1-9: device not accepting address 7, error -71 [ 67.156426] usb usb1-port9: unable to enumerate USB device [...] This issue does not manifest in 44a45be57f85. I am available to test any patches to address this on my system since I understand this could be quite hard to replicate on any system. I am available to provide more information if I am able or with guidance to help troubleshoot the issue further. Wishing you all a good day. #regzbot introduced: c0a40097f0bc81deafc15f9195d1fb54595cd6d0

[PATCH] x86/microcode/AMD: Fix out-of-bounds on systems with CPU-less NUMA nodes

by Florent Revest

Currently, load_microcode_amd() iterates over all NUMA nodes, retrieves their CPU masks and unconditonally accesses per-CPU data for the first CPU of each mask. According to Documentation/admin-guide/mm/numaperf.rst: "Some memory may share the same node as a CPU, and others are provided as memory only nodes." Therefore, some node CPU masks may be empty and wouldn't have a "first CPU". On a machine with far memory (and therefore CPU-less NUMA nodes): - cpumask_of_node(nid) is 0 - cpumask_first(0) is CONFIG_NR_CPUS - cpu_data(CONFIG_NR_CPUS) accesses the cpu_info per-CPU array at an index that is 1 out of bounds This does not have any security implications since flashing microcode is a privileged operation but I believe this has reliability implications by potentially corrupting memory while flashing a microcode update. When booting with CONFIG_UBSAN_BOUNDS=y on an AMD machine that flashes a microcode update. I get the following splat: UBSAN: array-index-out-of-bounds in arch/x86/kernel/cpu/microcode/amd.c:X:Y index 512 is out of range for type 'unsigned long[512]' [...] Call Trace: dump_stack+0xdb/0x143 __ubsan_handle_out_of_bounds+0xf5/0x120 load_microcode_amd+0x58f/0x6b0 request_microcode_amd+0x17c/0x250 reload_store+0x174/0x2b0 kernfs_fop_write_iter+0x227/0x2d0 vfs_write+0x322/0x510 ksys_write+0xb5/0x160 do_syscall_64+0x6b/0xa0 entry_SYSCALL_64_after_hwframe+0x67/0xd1 This patch checks that a NUMA node has CPUs before attempting to update its first CPU's microcode.

Apply 0c5928deada1 for 6.12.y and 6.13.y

by Miguel Ojeda

Hi Greg, Sasha, Please consider applying the following commits for 6.12.y and 6.13.y: 0c5928deada1 ("rust: block: fix formatting in GenDisk doc") It is trivial, and should apply cleanly. This avoids a Clippy warning in the upcoming Rust 1.86.0 release (to be released in a few weeks). Thanks! Cheers, Miguel

[PATCH] jffs2: check that raw node were preallocated before writing summary

Syzkaller detected a kernel bug in jffs2_link_node_ref, caused by fault injection in jffs2_prealloc_raw_node_refs. jffs2_sum_write_sumnode doesn't check return value of jffs2_prealloc_raw_node_refs and simply lets any error propagate into jffs2_sum_write_data, which eventually calls jffs2_link_node_ref in order to link the summary to an expectedly allocated node. kernel BUG at fs/jffs2/nodelist.c:592! invalid opcode: 0000 [#1] PREEMPT SMP KASAN NOPTI CPU: 1 PID: 31277 Comm: syz-executor.7 Not tainted 6.1.128-syzkaller-00139-ge10f83ca10a1 #0 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014 RIP: 0010:jffs2_link_node_ref+0x570/0x690 fs/jffs2/nodelist.c:592 Call Trace: <TASK> jffs2_sum_write_data fs/jffs2/summary.c:841 [inline] jffs2_sum_write_sumnode+0xd1a/0x1da0 fs/jffs2/summary.c:874 jffs2_do_reserve_space+0xa18/0xd60 fs/jffs2/nodemgmt.c:388 jffs2_reserve_space+0x55f/0xaa0 fs/jffs2/nodemgmt.c:197 jffs2_write_inode_range+0x246/0xb50 fs/jffs2/write.c:362 jffs2_write_end+0x726/0x15d0 fs/jffs2/file.c:301 generic_perform_write+0x314/0x5d0 mm/filemap.c:3856 __generic_file_write_iter+0x2ae/0x4d0 mm/filemap.c:3973 generic_file_write_iter+0xe3/0x350 mm/filemap.c:4005 call_write_iter include/linux/fs.h:2265 [inline] do_iter_readv_writev+0x20f/0x3c0 fs/read_write.c:735 do_iter_write+0x186/0x710 fs/read_write.c:861 vfs_iter_write+0x70/0xa0 fs/read_write.c:902 iter_file_splice_write+0x73b/0xc90 fs/splice.c:685 do_splice_from fs/splice.c:763 [inline] direct_splice_actor+0x10c/0x170 fs/splice.c:950 splice_direct_to_actor+0x337/0xa10 fs/splice.c:896 do_splice_direct+0x1a9/0x280 fs/splice.c:1002 do_sendfile+0xb13/0x12c0 fs/read_write.c:1255 __do_sys_sendfile64 fs/read_write.c:1323 [inline] __se_sys_sendfile64 fs/read_write.c:1309 [inline] __x64_sys_sendfile64+0x1cf/0x210 fs/read_write.c:1309 do_syscall_x64 arch/x86/entry/common.c:51 [inline] do_syscall_64+0x35/0x80 arch/x86/entry/common.c:81 entry_SYSCALL_64_after_hwframe+0x6e/0xd8 Fix this issue by checking return value of jffs2_prealloc_raw_node_refs before calling jffs2_sum_write_data.

[PATCH net v2] netmem: prevent TX of unreadable skbs

by Mina Almasry

Currently on stable trees we have support for netmem/devmem RX but not TX. It is not safe to forward/redirect an RX unreadable netmem packet into the device's TX path, as the device may call dma-mapping APIs on dma addrs that should not be passed to it. Fix this by preventing the xmit of unreadable skbs.

[PATCH v3] mm/migrate: fix shmem xarray update during migration

by Zi Yan

A shmem folio can be either in page cache or in swap cache, but not at the same time. Namely, once it is in swap cache, folio->mapping should be NULL, and the folio is no longer in a shmem mapping. In __folio_migrate_mapping(), to determine the number of xarray entries to update, folio_test_swapbacked() is used, but that conflates shmem in page cache case and shmem in swap cache case. It leads to xarray multi-index entry corruption, since it turns a sibling entry to a normal entry during xas_store() (see [1] for a userspace reproduction). Fix it by only using folio_test_swapcache() to determine whether xarray is storing swap cache entries or not to choose the right number of xarray entries to update. [1] https://lore.kernel.org/linux-mm/Z8idPCkaJW1IChjT@casper.infradead.org/ Note: In __split_huge_page(), folio_test_anon() && folio_test_swapcache() is used to get swap_cache address space, but that ignores the shmem folio in swap cache case. It could lead to NULL pointer dereferencing when a in-swap-cache shmem folio is split at __xa_store(), since !folio_test_anon() is true and folio->mapping is NULL. But fortunately, its caller split_huge_page_to_list_to_order() bails out early with EBUSY when folio->mapping is NULL. So no need to take care of it here.

[PATCH v2] iommufd: Fail replace if device has not been attached

by Yi Liu

The current implementation of iommufd_device_do_replace() implicitly assumes that the input device has already been attached. However, there is no explicit check to verify this assumption. If another device within the same group has been attached, the replace operation might succeed, but the input device itself may not have been attached yet. As a result, the input device might not be tracked in the igroup->device_list, and its reserved IOVA might not be added. Despite this, the caller might incorrectly assume that the device has been successfully replaced, which could lead to unexpected behavior or errors. To address this issue, add a check to ensure that the input device has been attached before proceeding with the replace operation. This check will help maintain the integrity of the device tracking system and prevent potential issues arising from incorrect assumptions about the device's attachment status.

[PATCH 2/2] virt: sev-guest: Move SNP Guest Request data pages handling under snp_cmd_mutex

by Alexey Kardashevskiy

Compared to the SNP Guest Request, the "Extended" version adds data pages for receiving certificates. If not enough pages provided, the HV can report to the VM how much is needed so the VM can reallocate and repeat. Commit ae596615d93d ("virt: sev-guest: Reduce the scope of SNP command mutex") moved handling of the allocated/desired pages number out of scope of said mutex and create a possibility for a race (multiple instances trying to trigger Extended request in a VM) as there is just one instance of snp_msg_desc per /dev/sev-guest and no locking other than snp_cmd_mutex. Fix the issue by moving the data blob/size and the GHCB input struct (snp_req_data) into snp_guest_req which is allocated on stack now and accessed by the GHCB caller under that mutex. Stop allocating SEV_FW_BLOB_MAX_SIZE in snp_msg_alloc() as only one of four callers needs it. Free the received blob in get_ext_report() right after it is copied to the userspace. Possible future users of snp_send_guest_request() are likely to have different ideas about the buffer size anyways.

On our board, the 002:00:07.0 bridge is misconfigured by the bootloader. Both its secondary and subordinate bus numbers are initialized to 0, while its fixed secondary bus number is set to 8. However, bus number 8 is also assigned to another bridge (0002:00:0f.0). Although this is a bootloader issue, before the change in commit 7246a4520b4b, the PCI_REASSIGN_ALL_BUS flag was set by default when PCI_PROBE_ONLY was enabled, ensuing that all the bus number for these bridges were reassigned, avoiding any conflicts. After the change introduced in commit 7246a4520b4b, the bus numbers assigned by the bootloader are reused by all other bridges, except the misconfigured 002:00:07.0 bridge. The kernel attempt to reconfigure 002:00:07.0 by reusing the fixed secondary bus number 8 assigned by bootloader. However, since a pci_bus has already been allocated for bus 8 due to the probe of 0002:00:0f.0, no new pci_bus allocated for 002:00:07.0. This results in a pci bridge device without a pci_bus attached (pdev->subordinate == NULL). Consequently, accessing pdev->subordinate in of_pci_prop_bus_range() leads to a NULL pointer dereference. To summarize, we need to restore the PCI_REASSIGN_ALL_BUS flag when PCI_PROBE_ONLY is enabled in order to work around issue like the one described above.

[PATCH v1] mm/madvise: Always set ptes via arch helpers

by Ryan Roberts

Instead of writing a pte directly into the table, use the set_pte_at() helper, which gives the arch visibility of the change. In this instance we are guaranteed that the pte was originally none and is being modified to a not-present pte, so there was unlikely to be a bug in practice (at least not on arm64). But it's bad practice to write the page table memory directly without arch involvement.

I could be wrong, but it seems > like get_mac_address() suffers from the same problem? Thank you for the feedback Andrew. I checked get_mac_address() before sending this patch and to me it looks like it does check the return value of control_read(). It accumulates the return value of each control_read() call into rd_mac_len and then checks if it not equal to what is expected (ETH_ALEN which is 6), I believe each call should return 2. > > Andrew

Apply 3 commits for 6.13.y

by Miguel Ojeda

Hi Greg, Sasha, Please consider applying the following commits for 6.13.y: 27c7518e7f1c ("rust: finish using custom FFI integer types") 1bae8729e50a ("rust: map `long` to `isize` and `char` to `u8`") 9b98be76855f ("rust: cleanup unnecessary casts") They should apply cleanly. This backports the custom FFI integer types, which in turn solves a build failure under `CONFIG_RUST_FW_LOADER_ABSTRACTIONS=y`. I will have to send something similar to 6.12.y, but it requires more commits -- I may do the `alloc` backport first we discussed the other day. Thanks! Cheers, Miguel

[PATCH v2] tty: Permit some TIOCL_SETSEL modes without CAP_SYS_ADMIN

by Günther Noack

With this, processes without CAP_SYS_ADMIN are able to use TIOCLINUX with subcode TIOCL_SETSEL, in the selection modes TIOCL_SETPOINTER, TIOCL_SELCLEAR and TIOCL_SELMOUSEREPORT. TIOCL_SETSEL was previously changed to require CAP_SYS_ADMIN, as this IOCTL let callers change the selection buffer and could be used to simulate keypresses. These three TIOCL_SETSEL selection modes, however, are safe to use, as they do not modify the selection buffer. This fixes a mouse support regression that affected Emacs (invisible mouse cursor).

[PATCH net v2 1/2] net: phy: nxp-c45-tja11xx: add TJA112X PHY configuration errata

by Andrei Botila

The most recent sillicon versions of TJA1120 and TJA1121 can achieve full silicon performance by putting the PHY in managed mode. It is necessary to apply these PHY writes before link gets established. Application of this fix is required after restart of device and wakeup from sleep.

[PATCH] x86/boot: Sanitize boot params before parsing command line

by Ard Biesheuvel

From: Ard Biesheuvel <ardb(a)kernel.org> The 5-level paging code parses the command line to look for the 'no5lvl' string, and does so very early, before sanitize_boot_params() has been called and has been given the opportunity to wipe bogus data from the fields in boot_params that are not covered by struct setup_header, and are therefore supposed to be initialized to zero by the bootloader. This triggers an early boot crash when using syslinux-efi to boot a recent kernel built with CONFIG_X86_5LEVEL=y and CONFIG_EFI_STUB=n, as the 0xff padding that now fills the unused PE/COFF header is copied into boot_params by the bootloader, and interpreted as the top half of the command line pointer. Fix this by sanitizing the boot_params before use. Note that there is no harm in calling this more than once; subsequent invocations are able to spot that the boot_params have already been cleaned up. Cc: <stable(a)vger.kernel.org> # v6.1+ Cc: "H.

Provide for this by adding an `unsigned long sz` parameter to the function. This follows the same pattern as huge_pte_clear() and set_huge_pte_at(). This commit makes the required interface modifications to the core mm as well as all arches that implement this function (arm64, loongarch, mips, parisc, powerpc, riscv, s390, sparc).

[PATCH] mm: memcontrol: fix swap counter leak from offline cgroup

by Muchun Song

The commit 6769183166b3 has removed the parameter of id from swap_cgroup_record() and get the memcg id from mem_cgroup_id(folio_memcg(folio)). However, the caller of it may update a different memcg's counter instead of folio_memcg(folio). E.g. in the caller of mem_cgroup_swapout(), @swap_memcg could be different with @memcg and update the counter of @swap_memcg, but swap_cgroup_record() records the wrong memcg's ID. When it is uncharged from __mem_cgroup_uncharge_swap(), the swap counter will leak since the wrong recorded ID. Fix it by bring the parameter of id back.

The problem boils down to how run_vmtests.sh (mis)calculates the size of the region it feeds to uffd-stress. The latter expects to see an amount of MiB while the former is just giving out the number of free hugepages halved down. This measurement discrepancy ends up violating uffd-stress' assertion on number of hugetlb pages allocated per CPU, causing it to bail out with the error above. This commit fixes that issue by adjusting run_vmtests.sh's half_ufd_size_MB calculation so it properly renders the region size in MiB, as expected, while maintaining all of its original constraints in place.

Carvalho" <raphaelsc(a)scylladb.com> Subject: mm: fix error handling in __filemap_get_folio() with FGP_NOWAIT Date: Mon, 24 Feb 2025 11:37:00 -0300 original report: https://lore.kernel.org/all/CAKhLTr1UL3ePTpYjXOx2AJfNk8Ku2EdcEfu+CH1sf3Asr=… When doing buffered writes with FGP_NOWAIT, under memory pressure, the system returned ENOMEM despite there being plenty of available memory, to be reclaimed from page cache. The user space used io_uring interface, which in turn submits I/O with FGP_NOWAIT (the fast path). retsnoop pointed to iomap_get_folio: 00:34:16.180612 -> 00:34:16.180651 TID/PID 253786/253721 (reactor-1/combined_tests): entry_SYSCALL_64_after_hwframe+0x76 do_syscall_64+0x82 __do_sys_io_uring_enter+0x265 io_submit_sqes+0x209 io_issue_sqe+0x5b io_write+0xdd xfs_file_buffered_write+0x84 iomap_file_buffered_write+0x1a6 32us [-ENOMEM] iomap_write_begin+0x408 iter=&{.inode=0xffff8c67aa031138,.len=4096,.flags=33,.iomap={.addr=0xffffffffffffffff,.length=4096,.type=1,.flags=3,.bdev=0x�� pos=0 len=4096 foliop=0xffffb32c296b7b80 ! 4us [-ENOMEM] iomap_get_folio iter=&{.inode=0xffff8c67aa031138,.len=4096,.flags=33,.iomap={.addr=0xffffffffffffffff,.length=4096,.type=1,.flags=3,.bdev=0x�� pos=0 len=4096 This is likely a regression caused by 66dabbb65d67 ("mm: return an ERR_PTR from __filemap_get_folio"), which moved error handling from io_map_get_folio() to __filemap_get_folio(), but broke FGP_NOWAIT handling, so ENOMEM is being escaped to user space. Had it correctly returned -EAGAIN with NOWAIT, either io_uring or user space itself would be able to retry the request. It's not enough to patch io_uring since the iomap interface is the one responsible for it, and pwritev2(RWF_NOWAIT) and AIO interfaces must return the proper error too. The patch was tested with scylladb test suite (its original reproducer), and the tests all pass now when memory is pressured.

The existing mremap() logic has grown organically over a very long period of time, resulting in code that is in many parts, very difficult to follow and full of subtleties and sources of confusion. In addition, it is difficult to thread state through the operation correctly, as function arguments have expanded, some parameters are expected to be temporarily altered during the operation, others are intended to remain static and some can be overridden. This series completely refactors the mremap implementation, sensibly separating functions, adding comments to explain the more subtle aspects of the implementation and making use of small structs to thread state through everything. The reason for doing so is to lay the groundwork for planned future changes to the mremap logic, changes which require the ability to easily pass around state. Additionally, it would be unhelpful to add yet more logic to code that is already difficult to follow without first refactoring it like this. The first patch in this series additionally fixes a bug when a VMA with start address zero is partially remapped. Tested on real hardware under heavy workload and all self tests are passing. This patch (of 7): Consider the case of a partial mremap() (that results in a VMA split) of an accountable VMA (i.e. which has the VM_ACCOUNT flag set) whose start address is zero, with the MREMAP_MAYMOVE flag specified and a scenario where a move does in fact occur: addr end | | v v |-------------| | vma | |-------------| 0 This move is affected by unmapping the range [addr, end). In order to prevent an incorrect decrement of accounted memory which has already been determined, the mremap() code in move_vma() clears VM_ACCOUNT from the VMA prior to doing so, before reestablishing it in each of the VMAs post-split: addr end | | v v |---| |---| | A | | B | |---| |---| Commit 6b73cff239e5 ("mm: change munmap splitting order and move_vma()") changed this logic such as to determine whether there is a need to do so by establishing account_start and account_end and, in the instance where such an operation is required, assigning them to vma->vm_start and vma->vm_end. Later the code checks if the operation is required for 'A' referenced above thusly: if (account_start) { ... } However, if the VMA described above has vma->vm_start == 0, which is now assigned to account_start, this branch will not be executed. As a result, the VMA 'A' above will remain stripped of its VM_ACCOUNT flag, incorrectly. The fix is to simply convert these variables to booleans and set them as required.

[PATCH v3 0/4] samsung: pinctrl: Add support for eint_fltcon_offset and filter selection on gs101

by Peter Griffin

Hi folks, This series fixes support for correctly saving and restoring fltcon0 and fltcon1 registers on gs101 for non-alive banks where the fltcon register offset is not at a fixed offset (unlike previous SoCs). This is done by adding a eint_fltcon_offset and providing GS101 specific pin macros that take an additional parameter (similar to how exynosautov920 handles it's eint_con_offset). Additionally the SoC specific suspend and resume callbacks are re-factored so that each SoC variant has it's own callback containing the peculiarities for that SoC. Finally support for filter selection on alive banks is added, this is currently only enabled for gs101. The code path can be excercised using `echo mem > /sys/power/state` regards, Peter To: Krzysztof Kozlowski <krzk(a)kernel.org> To: Sylwester Nawrocki <s.nawrocki(a)samsung.com> To: Alim Akhtar <alim.akhtar(a)samsung.com> To: Linus Walleij <linus.walleij(a)linaro.org> Cc: linux-arm-kernel(a)lists.infradead.org Cc: linux-samsung-soc(a)vger.kernel.org Cc: linux-gpio(a)vger.kernel.org Cc: linux-kernel(a)vger.kernel.org Cc: andre.draszik(a)linaro.org Cc: tudor.ambarus(a)linaro.org Cc: willmcvicker(a)google.com Cc: semen.protsenko(a)linaro.org Cc: kernel-team(a)android.com Cc: jaewon02.kim(a)samsung.com Signed-off-by: Peter Griffin <peter.griffin(a)linaro.org> --- Changes in v3: - Ensure EXYNOS_FLTCON_DIGITAL bit is cleared (Andre) - Make it obvious that exynos_eint_set_filter() is conditional on bank type (Andre) - Make it obvious exynos_set_wakeup() is conditional on bank type (Andre) - Align style where the '+' is placed first (Andre) - Remove unnecessary braces (Andre) - Link to v2: https://lore.kernel.org/r/20250301-pinctrl-fltcon-suspend-v2-0-a7eef9bb443b… Changes in v2: - Remove eint_flt_selectable bool as it can be deduced from EINT_TYPE_WKUP (Peter) - Move filter config register comment to header file (Andre) - Rename EXYNOS_FLTCON_DELAY to EXYNOS_FLTCON_ANALOG (Andre) - Remove misleading old comment (Andre) - Refactor exynos_eint_update_flt_reg() into a loop (Andre) - Split refactor of suspend/resume callbacks & gs101 parts into separate patches (Andre) - Link to v1: https://lore.kernel.org/r/20250120-pinctrl-fltcon-suspend-v1-0-e77900b2a854… --- Peter Griffin (4): pinctrl: samsung: add support for eint_fltcon_offset pinctrl: samsung: add dedicated SoC eint suspend/resume callbacks pinctrl: samsung: add gs101 specific eint suspend/resume callbacks pinctrl: samsung: Add filter selection support for alive bank on gs101 drivers/pinctrl/samsung/pinctrl-exynos-arm64.c | 150 ++++++------- drivers/pinctrl/samsung/pinctrl-exynos.c | 294 +++++++++++++++---------- drivers/pinctrl/samsung/pinctrl-exynos.h | 50 ++++- drivers/pinctrl/samsung/pinctrl-samsung.c | 12 +- drivers/pinctrl/samsung/pinctrl-samsung.h | 12 +- 5 files changed, 318 insertions(+), 200 deletions(-) --- base-commit: 0761652a3b3b607787aebc386d412b1d0ae8008c change-id: 20250120-pinctrl-fltcon-suspend-2333a137c4d4 Best regards, -- Peter Griffin <peter.griffin(a)linaro.org>

The unused bit mask was subsequently removed by commit 11c60f23ed13 ("integrity: Remove unused macro IMA_ACTION_RULE_FLAGS"). Restore the performance improvement by introducing the new mask IMA_NONACTION_RULE_FLAGS, equal to IMA_NONACTION_FLAGS without IMA_NEW_FILE, which is not a rule-specific flag. Finally, reset IMA_NONACTION_RULE_FLAGS instead of IMA_NONACTION_FLAGS in process_measurement(), if the IMA_CHANGE_ATTR atomic flag is set (after file metadata modification). With this patch, new files for which metadata were modified while they are still open, can be reopened before the last file close (when security.ima is written), since the IMA_NEW_FILE flag is not cleared anymore. Otherwise, appraisal fails because security.ima is missing (files with IMA_NEW_FILE set are an exception).

[PATCH v1 2/2] mm/slab/kvfree_rcu: Switch to WQ_MEM_RECLAIM wq

[PATCH] arm64: tegra: delete the Orin NX/Nano suspend key

by Ivy Huang

From: Ninad Malwade <nmalwade(a)nvidia.com> As per the Orin Nano Dev Kit schematic, GPIO_G.02 is not available on this device family. It should not be used at all on Orin NX/Nano. Having this unused pin mapped as the suspend key can lead to unpredictable behavior for low power modes. Orin NX/Nano uses GPIO_EE.04 as both a "power" button and a "suspend" button. However, we cannot have two gpio-keys mapped to the same GPIO. Therefore delete the "suspend" key.

Regression for PXE boot from patch "Remove the 'bugger off' message" in stable 6.6.18

by Ulrich Gemkow

Hello, starting with stable kernel 6.6.18 we have problems with PXE booting. A bisect shows that the following patch is guilty: From 768171d7ebbce005210e1cf8456f043304805c15 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel <ardb(a)kernel.org> Date: Tue, 12 Sep 2023 09:00:55 +0000 Subject: x86/boot: Remove the 'bugger off' message Signed-off-by: Ard Biesheuvel <ardb(a)kernel.org> Signed-off-by: Ingo Molnar <mingo(a)kernel.org> Acked-by: H. Peter Anvin (Intel) <hpa(a)zytor.com> Link: https://lore.kernel.org/r/20230912090051.4014114-21-ardb@google.com With this patch applied PXE starts, requests the kernel and the initrd. Without showing anything on the console, the boot process stops. It seems, that the kernel crashes very early. With stable kernel 6.6.17 PXE boot works without problems. Reverting this single patch (which is part of a larger set of patches) solved the problem for us, PXE boot is working again. We use the packages syslinux-efi and syslinux-common from Debian 12. The used boot files are /efi64/syslinux.efi and /ldlinux.e64. Our config-File (for 6.6.80) is attached. Regarding the patch description, we really do not boot with a floppy :-) Any help would be greatly appreciated, I have a bit of a bad feeling about simply reverting a patch at such a deep level in the kernel. Thank you and best regards Ulrich -- |----------------------------------------------------------------------- | Ulrich Gemkow | University of Stuttgart | Institute of Communication Networks and Computer Engineering (IKR) |-----------------------------------------------------------------------

[PATCH 03/15] usb: xhci: Don't skip on Stopped - Length Invalid

by Mathias Nyman

From: Michal Pecio <michal.pecio(a)gmail.com> Up until commit d56b0b2ab142 ("usb: xhci: ensure skipped isoc TDs are returned when isoc ring is stopped") in v6.11, the driver didn't skip missed isochronous TDs when handling Stoppend and Stopped - Length Invalid events. Instead, it erroneously cleared the skip flag, which would cause the ring to get stuck, as future events won't match the missed TD which is never removed from the queue until it's cancelled. This buggy logic seems to have been in place substantially unchanged since the 3.x series over 10 years ago, which probably speaks first and foremost about relative rarity of this case in normal usage, but by the spec I see no reason why it shouldn't be possible. After d56b0b2ab142, TDs are immediately skipped when handling those Stopped events. This poses a potential problem in case of Stopped - Length Invalid, which occurs either on completed TDs (likely already given back) or Link and No-Op TRBs. Such event won't be recognized as matching any TD (unless it's the rare Link TRB inside a TD) and will result in skipping all pending TDs, giving them back possibly before they are done, risking isoc data loss and maybe UAF by HW. As a compromise, don't skip and don't clear the skip flag on this kind of event. Then the next event will skip missed TDs. A downside of not handling Stopped - Length Invalid on a Link inside a TD is that if the TD is cancelled, its actual length will not be updated to account for TRBs (silently) completed before the TD was stopped. I had no luck producing this sequence of completion events so there is no compelling demonstration of any resulting disaster. It may be a very rare, obscure condition. The sole motivation for this patch is that if such unlikely event does occur, I'd rather risk reporting a cancelled partially done isoc frame as empty than gamble with UAF. This will be fixed more properly by looking at Stopped event's TRB pointer when making skipping decisions, but such rework is unlikely to be backported to v6.12, which will stay around for a few years.

[PATCH v2 0/4] samsung: pinctrl: Add support for eint_fltcon_offset and filter selection on gs101

by Peter Griffin

Hi folks, This series fixes support for correctly saving and restoring fltcon0 and fltcon1 registers on gs101 for non-alive banks where the fltcon register offset is not at a fixed offset (unlike previous SoCs). This is done by adding a eint_fltcon_offset and providing GS101 specific pin macros that take an additional parameter (similar to how exynosautov920 handles it's eint_con_offset). Additionally the SoC specific suspend and resume callbacks are re-factored so that each SoC variant has it's own callback containing the peculiarities for that SoC. Finally support for filter selection on alive banks is added, this is currently only enabled for gs101. The code path can be excercised using `echo mem > /sys/power/state` regards, Peter To: Krzysztof Kozlowski <krzk(a)kernel.org> To: Sylwester Nawrocki <s.nawrocki(a)samsung.com> To: Alim Akhtar <alim.akhtar(a)samsung.com> To: Linus Walleij <linus.walleij(a)linaro.org> Cc: linux-arm-kernel(a)lists.infradead.org Cc: linux-samsung-soc(a)vger.kernel.org Cc: linux-gpio(a)vger.kernel.org Cc: linux-kernel(a)vger.kernel.org Cc: andre.draszik(a)linaro.org Cc: tudor.ambarus(a)linaro.org Cc: willmcvicker(a)google.com Cc: semen.protsenko(a)linaro.org Cc: kernel-team(a)android.com Cc: jaewon02.kim(a)samsung.com Signed-off-by: Peter Griffin <peter.griffin(a)linaro.org> --- Changes in v2: - Remove eint_flt_selectable bool as it can be deduced from EINT_TYPE_WKUP (Peter) - Move filter config register comment to header file (Andre) - Rename EXYNOS_FLTCON_DELAY to EXYNOS_FLTCON_ANALOG (Andre) - Remove misleading old comment (Andre) - Refactor exynos_eint_update_flt_reg() into a loop (Andre) - Split refactor of suspend/resume callbacks & gs101 parts into separate patches (Andre) - Link to v1: https://lore.kernel.org/r/20250120-pinctrl-fltcon-suspend-v1-0-e77900b2a854… --- Peter Griffin (4): pinctrl: samsung: add support for eint_fltcon_offset pinctrl: samsung: add dedicated SoC eint suspend/resume callbacks pinctrl: samsung: add gs101 specific eint suspend/resume callbacks pinctrl: samsung: Add filter selection support for alive bank on gs101 drivers/pinctrl/samsung/pinctrl-exynos-arm64.c | 150 ++++++------- drivers/pinctrl/samsung/pinctrl-exynos.c | 293 +++++++++++++++---------- drivers/pinctrl/samsung/pinctrl-exynos.h | 51 ++++- drivers/pinctrl/samsung/pinctrl-samsung.c | 12 +- drivers/pinctrl/samsung/pinctrl-samsung.h | 12 +- 5 files changed, 321 insertions(+), 197 deletions(-) --- base-commit: f7da3699c901aea6a009d38116d24c67a4c9662e change-id: 20250120-pinctrl-fltcon-suspend-2333a137c4d4 Best regards, -- Peter Griffin <peter.griffin(a)linaro.org>

[PATCH 13/15] usb: xhci: Apply the link chain quirk on NEC isoc endpoints

by Mathias Nyman

From: Michal Pecio <michal.pecio(a)gmail.com> Two clearly different specimens of NEC uPD720200 (one with start/stop bug, one without) were seen to cause IOMMU faults after some Missed Service Errors. Faulting address is immediately after a transfer ring segment and patched dynamic debug messages revealed that the MSE was received when waiting for a TD near the end of that segment: [ 1.041954] xhci_hcd: Miss service interval error for slot 1 ep 2 expected TD DMA ffa08fe0 [ 1.042120] xhci_hcd: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0005 address=0xffa09000 flags=0x0000] [ 1.042146] xhci_hcd: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0005 address=0xffa09040 flags=0x0000] It gets even funnier if the next page is a ring segment accessible to the HC. Below, it reports MSE in segment at ff1e8000, plows through a zero-filled page at ff1e9000 and starts reporting events for TRBs in page at ff1ea000 every microframe, instead of jumping to seg ff1e6000.

Lastly, an error from a different USB device on another HC. Was it caused by the above? I don't know, but it may have been. The disk was working without any other issues and generated PCIe traffic to starve the NEC of upstream BW and trigger those MSEs.

Other ancient HCs are known which also expect the bit to be set and they ignore Link TRBs if it's not. Reportedly, 0.95 spec guaranteed that the bit is set. The bandwidth-starved NEC HC running a 32KB/uframe UVC endpoint reports tens of MSEs per second and runs into the bug within seconds. Chaining Link TRBs allows the same workload to run for many minutes, many times. No negative side effects seen in UVC recording and UAC playback with a few devices at full speed, high speed and SuperSpeed. The problem doesn't reproduce on the newer Renesas uPD720201/uPD720202 and on old Etron EJ168 and VIA VL805 (but the VL805 has other bug).

[PATCH] drm/amd/display: fix missing .is_two_pixels_per_container

by Aliaksei Urbanski

Starting from 6.11, AMDGPU driver, while being loaded with amdgpu.dc=1, due to lack of .is_two_pixels_per_container function in dce60_tg_funcs, causes a NULL pointer dereference on PCs with old GPUs, such as R9 280X. So this fix adds missing .is_two_pixels_per_container to dce60_tg_funcs.

Provide for this by adding an `unsigned long sz` parameter to the function. This follows the same pattern as huge_pte_clear() and set_huge_pte_at(). This commit makes the required interface modifications to the core mm as well as all arches that implement this function (arm64, loongarch, mips, parisc, powerpc, riscv, s390, sparc). The actual arm64 bug will be fixed in a separate commit.

Provide for this by adding an `unsigned long sz` parameter to the function. This follows the same pattern as huge_pte_clear() and set_huge_pte_at(). This commit makes the required interface modifications to the core mm as well as all arches that implement this function (arm64, loongarch, mips, parisc, powerpc, riscv, s390, sparc). The actual arm64 bug will be fixed in a separate commit.

[PATCH v1] usb: core: fix pipe creation for get_bMaxPacketSize0

by Stefan Eichenberger

From: Stefan Eichenberger <stefan.eichenberger(a)toradex.com> When usb_control_msg is used in the get_bMaxPacketSize0 function, the USB pipe does not include the endpoint device number. This can cause failures when a usb hub port is reinitialized after encountering a bad cable connection. As a result, the system logs the following error messages: usb usb2-port1: cannot reset (err = -32) usb usb2-port1: Cannot enable. Maybe the USB cable is bad? usb usb2-port1: attempt power cycle usb 2-1: new high-speed USB device number 5 using ci_hdrc usb 2-1: device descriptor read/8, error -71 The problem began after commit 85d07c556216 ("USB: core: Unite old scheme and new scheme descriptor reads"). There usb_get_device_descriptor was replaced with get_bMaxPacketSize0. Unlike usb_get_device_descriptor, the get_bMaxPacketSize0 function uses the macro usb_rcvaddr0pipe, which does not include the endpoint device number. usb_get_device_descriptor, on the other hand, used the macro usb_rcvctrlpipe, which includes the endpoint device number. By modifying the get_bMaxPacketSize0 function to use usb_rcvctrlpipe instead of usb_rcvaddr0pipe, the issue can be resolved. This change will ensure that the endpoint device number is included in the USB pipe, preventing reinitialization failures. If the endpoint has not set the device number yet, it will still work because the device number is 0 in udev. Cc: stable(a)vger.kernel.org Fixes: 85d07c556216 ("USB: core: Unite old scheme and new scheme descriptor reads") Signed-off-by: Stefan Eichenberger <stefan.eichenberger(a)toradex.com> --- Before commit 85d07c556216 ("USB: core: Unite old scheme and new scheme descriptor reads") usb_rcvaddr0pipe was used in hub_port_init. With this proposed change, usb_rcvctrlpipe will be used which includes devnum for the pipe. I'm not sure if this might have some side effects. However, my understanding is that devnum is set to the right value (might also be 0 if not initialised) before get_bMaxPacketSize0 is called. Therefore, this should work but please let me know if I'm wrong on this. --- drivers/usb/core/hub.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/usb/core/hub.c b/drivers/usb/core/hub.c index c3f839637cb5..59e38780f76d 100644 --- a/drivers/usb/core/hub.c +++ b/drivers/usb/core/hub.c @@ -4698,7 +4698,6 @@ void usb_ep0_reinit(struct usb_device *udev) EXPORT_SYMBOL_GPL(usb_ep0_reinit); #define usb_sndaddr0pipe() (PIPE_CONTROL << 30) -#define usb_rcvaddr0pipe() ((PIPE_CONTROL << 30) | USB_DIR_IN) static int hub_set_address(struct usb_device *udev, int devnum) { @@ -4804,7 +4803,7 @@ static int get_bMaxPacketSize0(struct usb_device *udev, for (i = 0; i < GET_MAXPACKET0_TRIES; ++i) { /* Start with invalid values in case the transfer fails */ buf->bDescriptorType = buf->bMaxPacketSize0 = 0; - rc = usb_control_msg(udev, usb_rcvaddr0pipe(), + rc = usb_control_msg(udev, usb_rcvctrlpipe(udev, 0), USB_REQ_GET_DESCRIPTOR, USB_DIR_IN, USB_DT_DEVICE << 8, 0, buf, size, -- 2.45.2

[PATCH 5.10.y 0/3] vsock: fix use-after free and null-ptr-deref

Hi all, This series backports three upstream commits: - 135ffc7 "bpf, vsock: Invoke proto::close on close()" - fcdd224 "vsock: Keep the binding until socket destruction" - 78dafe1 "vsock: Orphan socket after transport release" Although this version of the kernel does not support sockmap, I think backporting this patch can be useful to reduce conflicts in future backports [1]. It does not harm the system. The comment it introduces in the code can be misleading. I added some words in the commit to explain the situation. The other two commits are untouched, fixing a use-after free[2] and a null-ptr-deref[3] respectively.

[PATCHv3 perf/core] uprobes: Harden uretprobe syscall trampoline check

by Jiri Olsa

Jann reported [1] possible issue when trampoline_check_ip returns address near the bottom of the address space that is allowed to call into the syscall if uretprobes are not set up. Though the mmap minimum address restrictions will typically prevent creating mappings there, let's make sure uretprobe syscall checks for that.

[PATCH] USB: serial: option: match on interface class for Telit FN990B

by Johan Hovold

The device id entries for Telit FN990B ended up matching only on the interface protocol. While this works, the protocol is qualified by the interface class (and subclass) which should have been included. Switch to matching using USB_DEVICE_AND_INTERFACE_INFO() while keeping the entries sorted also by protocol for consistency.

[PATCH v2 1/2] Revert "drivers: core: synchronize really_probe() and dev_uevent()"

by Dmitry Torokhov

This reverts commit c0a40097f0bc81deafc15f9195d1fb54595cd6d0. Probing a device can take arbitrary long time. In the field we observed that, for example, probing a bad micro-SD cards in an external USB card reader (or maybe cards were good but cables were flaky) sometimes takes longer than 2 minutes due to multiple retries at various levels of the stack. We can not block uevent_show() method for that long because udev is reading that attribute very often and that blocks udev and interferes with booting of the system. The change that introduced locking was concerned with dev_uevent() racing with unbinding the driver. However we can handle it without locking (which will be done in subsequent patch). There was also claim that synchronization with probe() is needed to properly load USB drivers, however this is a red herring: the change adding the lock was introduced in May of last year and USB loading and probing worked properly for many years before that. Revert the harmful locking.

[PATCH] qlcnic: fix a memory leak in __qlcnic_pci_sriov_enable()

Please apply f24f669d03f8 ("x86/mm: Don't disable PCID when INVLPG has been fixed by microcode")

by Thomas Voegtle

Hi, please apply f24f669d03f8 for 6.12.y. It is already in 6.13.y. Backports of that patch would be needed for 6.6.y down to 5.4.y as it doesn't apply. But I don't know how to backport that fix but I can test anything. Thomas

[PATCH net v2] net/mlx5: handle errors in mlx5_chains_create_table()

by Wentao Liang

In mlx5_chains_create_table(), the return value of mlx5_get_fdb_sub_ns() and mlx5_get_flow_namespace() must be checked to prevent NULL pointer dereferences. If either function fails, the function should log error message with mlx5_core_warn() and return error pointer. [v1]->[v2]: Add Fixes tag. Target patch to net.

[PATCH] RDMA/mlx5: Prevent UB from shifting negative signed value

by Qasim Ijaz

In function create_ib_ah() the following line attempts to left shift the return value of mlx5r_ib_rate() by 4 and store it in the stat_rate_sl member of av: ah->av.stat_rate_sl = (mlx5r_ib_rate(dev, rdma_ah_get_static_rate(ah_attr)) << 4); However the code overlooks the fact that mlx5r_ib_rate() may return -EINVAL if the rate passed to it is less than IB_RATE_2_5_GBPS or greater than IB_RATE_800_GBPS. Because of this, the code may invoke undefined behaviour when shifting a signed negative value when doing "-EINVAL << 4". To fix this check for errors before assigning stat_rate_sl and propagate any error value to the callers.
