With regards to the important vm_ops->close() callback We have gone to great lengths to try to track whether or not we ought to close VMAs. Rather than doing so and risking making a mistake somewhere, instead unconditionally close and reset vma->vm_ops to an empty dummy operations set with a NULL .close operator. We introduce a new function to do so - vma_close() - and simplify existing vms logic which tracked whether we needed to close or not. This simplifies the logic, avoids incorrect double-calling of the .close() callback and allows us to update error paths to simply call vma_close() unconditionally - making VMA closure idempotent.

The mmap_region() function is somewhat terrifying, with spaghetti-like control flow and numerous means by which issues can arise and incomplete state, memory leaks and other unpleasantness can occur. A large amount of the complexity arises from trying to handle errors late in the process of mapping a VMA, which forms the basis of recently observed issues with resource leaks and observable inconsistent state. This series goes to great lengths to simplify how mmap_region() works and to avoid unwinding errors late on in the process of setting up the VMA for the new mapping, and equally avoids such operations occurring while the VMA is in an inconsistent state. The first four patches are intended for backporting to correct the possibility of people encountering corrupted state while invoking mmap() which is otherwise at risk of happening. After this we go further, refactoring the code, placing it in mm/vma.c in order to make it eventually userland testable, and significantly simplifying the logic to avoid this issue arising in future. This patch (of 4): After an attempted mmap() fails, we are no longer in a situation where we can safely interact with VMA hooks. This is currently not enforced, meaning that we need complicated handling to ensure we do not incorrectly call these hooks. We can avoid the whole issue by treating the VMA as suspect the moment that the file->f_ops->mmap() function reports an error by replacing whatever VMA operations were installed with a dummy empty set of VMA operations. We do so through a new helper function internal to mm - mmap_file() - which is both more logically named than the existing call_mmap() function and correctly isolates handling of the vm_op reassignment to mm. All the existing invocations of call_mmap() outside of mm are ultimately nested within the call_mmap() from mm, which we now replace. It is therefore safe to leave call_mmap() in place as a convenience function (and to avoid churn). The invokers are: ovl_file_operations -> mmap -> ovl_mmap() -> backing_file_mmap() coda_file_operations -> mmap -> coda_file_mmap() shm_file_operations -> shm_mmap() shm_file_operations_huge -> shm_mmap() dma_buf_fops -> dma_buf_mmap_internal -> i915_dmabuf_ops -> i915_gem_dmabuf_mmap() None of these callers interact with vm_ops or mappings in a problematic way on error, quickly exiting out.

[PATCH v1 1/2] mseal: Two fixes for madvise(MADV_DONTNEED) when sealed

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)chromium.org> Two fixes for madvise(MADV_DONTNEED) when sealed. For PROT_NONE mappings, the previous blocking of madvise(MADV_DONTNEED) is unnecessary. As PROT_NONE already prohibits memory access, madvise(MADV_DONTNEED) should be allowed to proceed in order to free the page. For file-backed, private, read-only memory mappings, we previously did not block the madvise(MADV_DONTNEED). This was based on the assumption that the memory's content, being file-backed, could be retrieved from the file if accessed again. However, this assumption failed to consider scenarios where a mapping is initially created as read-write, modified, and subsequently changed to read-only. The newly introduced VM_WASWRITE flag addresses this oversight.

[PATCH stable 5.4] mtd: rawnand: protect access to rawnand devices while in suspend

by Florian Fainelli

From: Sean Nyekjaer <sean(a)geanix.com> commit 8cba323437a49a45756d661f500b324fc2d486fe upstream. Prevent rawnand access while in a suspended state. Commit 013e6292aaf5 ("mtd: rawnand: Simplify the locking") allows the rawnand layer to return errors rather than waiting in a blocking wait. Tested on a iMX6ULL.

[PATCH v7 2/5] tpm: Implement tpm2_load_null() rollback

by Jarkko Sakkinen

tpm2_load_null() has weak and broken error handling: - The return value of tpm2_create_primary() is ignored. - Leaks TPM return codes from tpm2_load_context() to the caller. - If the key name comparison succeeds returns previous error instead of zero to the caller. Implement a proper error rollback.

[PATCH 6.1.y 5.15.y 5.10.y 5.4.y 4.19.y] vt: prevent kernel-infoleak in con_font_get()

by Jeongjun Park

commit f956052e00de211b5c9ebaa1958366c23f82ee9e upstream. font.data may not initialize all memory spaces depending on the implementation of vc->vc_sw->con_font_get. This may cause info-leak, so to prevent this, it is safest to modify it to initialize the allocated memory space to 0, and it generally does not affect the overall performance of the system.

[PATCH AUTOSEL 6.6 01/23] 9p: v9fs_fid_find: also lookup by inode if not found dentry

From: Dominique Martinet <asmadeus(a)codewreck.org> [ Upstream commit 38d222b3163f7b7d737e5d999ffc890a12870e36 ] It's possible for v9fs_fid_find "find by dentry" branch to not turn up anything despite having an entry set (because e.g. uid doesn't match), in which case the calling code will generally make an extra lookup to the server.

[PATCH v4 0/3] Fix KASAN crash when using KASAN_VMALLOC

by Linus Walleij

This problem reported by Clement LE GOFFIC manifest when using CONFIG_KASAN_IN_VMALLOC and VMAP_STACK: https://lore.kernel.org/linux-arm-kernel/a1a1d062-f3a2-4d05-9836-3b098de9db… After some analysis it seems we are missing to sync the VMALLOC shadow memory in top level PGD to all CPUs. Add some code to perform this sync, and the bug appears to go away. As suggested by Ard, also perform a dummy read from the shadow memory of the new VMAP_STACK in the low level assembly. Signed-off-by: Linus Walleij <linus.walleij(a)linaro.org> --- Changes in v4: - Since Kasan is not using header stubs, it is necessary to avoid kasan_*() calls using ifdef when compiling without KASAN. - Lift a line aligning the end of vmalloc from Melon Liu's very similar patch so we have feature parity, credit Melon as co-developer. - Include the atomic_read_acquire() patch in the series due to context requirements. - Verify that the after the patch the kernel still builds and boots without Kasan. - Link to v3: https://lore.kernel.org/r/20241017-arm-kasan-vmalloc-crash-v3-0-d2a34cd5b66… Changes in v3: - Collect Mark Rutlands ACK on patch 1 - Change the simplified assembly add r2, ip, lsr #n to the canonical add r2, r2, ip, lsr #n in patch 2. - Link to v2: https://lore.kernel.org/r/20241016-arm-kasan-vmalloc-crash-v2-0-0a52fd086ee… Changes in v2: - Implement the two helper functions suggested by Russell making the KASAN PGD copying less messy. - Link to v1: https://lore.kernel.org/r/20241015-arm-kasan-vmalloc-crash-v1-0-dbb23592ca8… --- Linus Walleij (3): ARM: ioremap: Sync PGDs for VMALLOC shadow ARM: entry: Do a dummy read from VMAP shadow mm: Pair atomic_set_release() with _read_acquire() arch/arm/kernel/entry-armv.S | 8 ++++++++ arch/arm/mm/ioremap.c | 35 ++++++++++++++++++++++++++++++----- 2 files changed, 38 insertions(+), 5 deletions(-) --- base-commit: 9852d85ec9d492ebef56dc5f229416c925758edc change-id: 20241015-arm-kasan-vmalloc-crash-fcbd51416457 Best regards, -- Linus Walleij <linus.walleij(a)linaro.org>

[PATCH] drm/i915/gt: Cleanup partial engine discovery failures

by kai.kang＠windriver.com

From: Chris Wilson <chris.p.wilson(a)intel.com> commit 78a033433a5ae4fee85511ee075bc9a48312c79e upstream. If we abort driver initialisation in the middle of gt/engine discovery, some engines will be fully setup and some not.

[PATCH wireless] wifi: iwlwifi: mvm: fix 6 GHz scan construction

by Johannes Berg

From: Johannes Berg <johannes.berg(a)intel.com> If more than 255 colocated APs exist for the set of all APs found during 2.5/5 GHz scanning, then the 6 GHz scan construction will loop forever since the loop variable has type u8, which can never reach the number found when that's bigger than 255, and is stored in a u32 variable. Also move it into the loops to have a smaller scope. Using a u32 there is fine, we limit the number of APs in the scan list and each has a limit on the number of RNR entries due to the frame size. With a limit of 1000 scan results, a frame size upper bound of 4096 (really it's more like ~2300) and a TBTT entry size of at least 11, we get an upper bound for the number of ~372k, well in the bounds of a u32.

[PATCH 04/16] Revert "drm/amd/display: update DML2 policy EnhancedPrefetchScheduleAccelerationFinal DCN35"

From: Ovidiu Bunea <Ovidiu.Bunea(a)amd.com> This reverts commit db88df35a509 ("drm/amd/display: update DML2 policy EnhancedPrefetchScheduleAccelerationFinal DCN35") [why & how] The offending commit exposes a hang with lid close/open behavior.

[PATCH] clk: qcom: gcc-qcs404: fix initial rate of GPLL3

by Gabor Juhos

The comment before the config of the GPLL3 PLL says that the PLL should run at 930 MHz. In contrary to this, calculating the frequency from the current configuration values by using 19.2 MHz as input frequency defined in 'qcs404.dtsi', it gives 921.6 MHz: $ xo=19200000; l=48; alpha=0x0; alpha_hi=0x0 $ echo "$xo * ($((l)) + $(((alpha_hi << 32 | alpha) >> 8)) / 2^32)" | bc -l 921600000.00000000000000000000 Set 'alpha_hi' in the configuration to a value used in downstream kernels [1][2] in order to get the correct output rate: $ xo=19200000; l=48; alpha=0x0; alpha_hi=0x70 $ echo "$xo * ($((l)) + $(((alpha_hi << 32 | alpha) >> 8)) / 2^32)" | bc -l 930000000.00000000000000000000 The change is based on static code analysis, compile tested only.

[PATCH OLK-6.6 3/3] LoongArch: Define __ARCH_WANT_NEW_STAT in unistd.h

by Hongchen Zhang

From: Huacai Chen <chenhuacai(a)loongson.cn> mainline inclusion from mainline-v6.11-rc1 commit 7697a0fe0154468f5df35c23ebd7aa48994c2cdc category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IAZ33N CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ---------------------------------------------------------------------- Chromium sandbox apparently wants to deny statx [1] so it could properly inspect arguments after the sandboxed process later falls back to fstat. Because there's currently not a "fd-only" version of statx, so that the sandbox has no way to ensure the path argument is empty without being able to peek into the sandboxed process's memory. For architectures able to do newfstatat though, glibc falls back to newfstatat after getting -ENOSYS for statx, then the respective SIGSYS handler [2] takes care of inspecting the path argument, transforming allowed newfstatat's into fstat instead which is allowed and has the same type of return value. But, as LoongArch is the first architecture to not have fstat nor newfstatat, the LoongArch glibc does not attempt falling back at all when it gets -ENOSYS for statx -- and you see the problem there! Actually, back when the LoongArch port was under review, people were aware of the same problem with sandboxing clone3 [3], so clone was eventually kept. Unfortunately it seemed at that time no one had noticed statx, so besides restoring fstat/newfstatat to LoongArch uapi (and postponing the problem further), it seems inevitable that we would need to tackle seccomp deep argument inspection. However, this is obviously a decision that shouldn't be taken lightly, so we just restore fstat/newfstatat by defining __ARCH_WANT_NEW_STAT in unistd.h. This is the simplest solution for now, and so we hope the community will tackle the long-standing problem of seccomp deep argument inspection in the future [4][5]. Also add "newstat" to syscall_abis_64 in Makefile.syscalls due to upstream asm-generic changes. More infomation please reading this thread [6].

[PATCH] mm: avoid unconditional one-tick sleep when swapcache_prepare fails

by Barry Song

From: Barry Song <v-songbaohua(a)oppo.com> Commit 13ddaf26be32 ("mm/swap: fix race when skipping swapcache") introduced an unconditional one-tick sleep when `swapcache_prepare()` fails, which has led to reports of UI stuttering on latency-sensitive Android devices. To address this, we can use a waitqueue to wake up tasks that fail `swapcache_prepare()` sooner, instead of always sleeping for a full tick. While tasks may occasionally be woken by an unrelated `do_swap_page()`, this method is preferable to two scenarios: rapid re-entry into page faults, which can cause livelocks, and multiple millisecond sleeps, which visibly degrade user experience. Oven's testing shows that a single waitqueue resolves the UI stuttering issue. If a 'thundering herd' problem becomes apparent later, a waitqueue hash similar to `folio_wait_table[PAGE_WAIT_TABLE_SIZE]` for page bit locks can be introduced.

[PATCH 0/5] cxl: Initialization and shutdown fixes

by Dan Williams

Gregory's modest proposal to fix CXL cxl_mem_probe() failures due to delayed arrival of the CXL "root" infrastructure [1] prompted questions of how the existing mechanism for retrying cxl_mem_probe() could be failing. The critical missing piece in the debug was that Gregory's setup had almost all CXL modules built-in to the kernel. On the way to that discovery several other bugs and init-order corner cases were discovered. The main fix is to make sure the drivers/cxl/Makefile object order supports root CXL ports being fully initialized upon cxl_acpi_probe() exit. The modular case has some similar potential holes that are fixed with MODULE_SOFTDEP() and other fix ups. Finally, an attempt to update cxl_test to reproduce the original report resulted in the discovery of a separate long standing use after free bug in cxl_region_detach().

The quilt patch titled Subject: nilfs2: fix kernel bug due to missing clearing of buffer delay flag has been removed from the -mm tree. Its filename was nilfs2-fix-kernel-bug-due-to-missing-clearing-of-buffer-delay-flag.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> Subject: nilfs2: fix kernel bug due to missing clearing of buffer delay flag Date: Wed, 16 Oct 2024 06:32:07 +0900 Syzbot reported that after nilfs2 reads a corrupted file system image and degrades to read-only, the BUG_ON check for the buffer delay flag in submit_bh_wbc() may fail, causing a kernel bug. This is because the buffer delay flag is not cleared when clearing the buffer state flags to discard a page/folio or a buffer head. So, fix this. This became necessary when the use of nilfs2's own page clear routine was expanded. This state inconsistency does not occur if the buffer is written normally by log writing.

[PATCH v2] ASoC: qcom: sc7280: Fix missing Soundwire runtime stream alloc

by Krzysztof Kozlowski

Commit 15c7fab0e047 ("ASoC: qcom: Move Soundwire runtime stream alloc to soundcards") moved the allocation of Soundwire stream runtime from the Qualcomm Soundwire driver to each individual machine sound card driver, except that it forgot to update SC7280 card. Just like for other Qualcomm sound cards using Soundwire, the card driver should allocate and release the runtime.

[tip: locking/core] locking/lockdep: Avoid creating new name string literals in lockdep_set_subclass()

by tip-bot2 for Ahmed Ehab

The following commit has been merged into the locking/core branch of tip: Commit-ID: d7fe143cb115076fed0126ad8cf5ba6c3e575e43 Gitweb: https://git.kernel.org/tip/d7fe143cb115076fed0126ad8cf5ba6c3e575e43 Author: Ahmed Ehab <bottaawesome633(a)gmail.com> AuthorDate: Sun, 25 Aug 2024 01:10:30 +03:00 Committer: Boqun Feng <boqun.feng(a)gmail.com> CommitterDate: Thu, 17 Oct 2024 20:07:23 -07:00 locking/lockdep: Avoid creating new name string literals in lockdep_set_subclass() Syzbot reports a problem that a warning will be triggered while searching a lock class in look_up_lock_class(). The cause of the issue is that a new name is created and used by lockdep_set_subclass() instead of using the existing one. This results in a lock instance has a different name pointer than previous registered one stored in lock class, and WARN_ONCE() is triggered because of that in look_up_lock_class(). To fix this, change lockdep_set_subclass() to use the existing name instead of a new one. Hence, no new name will be created by lockdep_set_subclass(). Hence, the warning is avoided.

[PATCH 5.10] exec: don't WARN for racy path_noexec check

by Thadeu Lima de Souza Cascardo

From: Mateusz Guzik <mjguzik(a)gmail.com> [ Upstream commit 0d196e7589cefe207d5d41f37a0a28a1fdeeb7c6 ] Both i_mode and noexec checks wrapped in WARN_ON stem from an artifact of the previous implementation. They used to legitimately check for the condition, but that got moved up in two commits: 633fb6ac3980 ("exec: move S_ISREG() check earlier") 0fd338b2d2cd ("exec: move path_noexec() check earlier") Instead of being removed said checks are WARN_ON'ed instead, which has some debug value. However, the spurious path_noexec check is racy, resulting in unwarranted warnings should someone race with setting the noexec flag. One can note there is more to perm-checking whether execve is allowed and none of the conditions are guaranteed to still hold after they were tested for. Additionally this does not validate whether the code path did any perm checking to begin with -- it will pass if the inode happens to be regular. Keep the redundant path_noexec() check even though it's mindless nonsense checking for guarantee that isn't given so drop the WARN. Reword the commentary and do small tidy ups while here.

[PATCH iwl-net 1/2] idpf: avoid vport access in idpf_get_link_ksettings

by Pavan Kumar Linga

When the device control plane is removed or the platform running device control plane is rebooted, a reset is detected on the driver. On driver reset, it releases the resources and waits for the reset to complete. If the reset fails, it takes the error path and releases the vport lock. At this time if the monitoring tools tries to access link settings, it call traces for accessing released vport pointer. To avoid it, move link_speed_mbps to netdev_priv structure which removes the dependency on vport pointer and the vport lock in idpf_get_link_ksettings. Also use netif_carrier_ok() to check the link status and adjust the offsetof to use link_up instead of link_speed_mbps.

[PATCH v2] mm: Split critical region in remap_file_pages() and invoke LSMs in between

by Roberto Sassu

From: "Kirill A. Shutemov" <kirill.shutemov(a)linux.intel.com> Commit ea7e2d5e49c0 ("mm: call the security_mmap_file() LSM hook in remap_file_pages()") fixed a security issue, it added an LSM check when trying to remap file pages, so that LSMs have the opportunity to evaluate such action like for other memory operations such as mmap() and mprotect(). However, that commit called security_mmap_file() inside the mmap_lock lock, while the other calls do it before taking the lock, after commit 8b3ec6814c83 ("take security_mmap_file() outside of ->mmap_sem"). This caused lock inversion issue with IMA which was taking the mmap_lock and i_mutex lock in the opposite way when the remap_file_pages() system call was called. Solve the issue by splitting the critical region in remap_file_pages() in two regions: the first takes a read lock of mmap_lock, retrieves the VMA and the file descriptor associated, and calculates the 'prot' and 'flags' variables; the second takes a write lock on mmap_lock, checks that the VMA flags and the VMA file descriptor are the same as the ones obtained in the first critical region (otherwise the system call fails), and calls do_mmap(). In between, after releasing the read lock and before taking the write lock, call security_mmap_file(), and solve the lock inversion issue.

[PATCH v2] xhci: Fix Link TRB DMA in command ring stopped completion event

by Faisal Hassan

During the aborting of a command, the software receives a command completion event for the command ring stopped, with the TRB pointing to the next TRB after the aborted command. If the command we abort is located just before the Link TRB in the command ring, then during the 'command ring stopped' completion event, the xHC gives the Link TRB in the event's cmd DMA, which causes a mismatch in handling command completion event. To handle this situation, an additional check has been added to ignore the mismatch error and continue the operation. Fixes: 7f84eef0dafb ("USB: xhci: No-op command queueing and irq handler.")

[PATCH v4 1/1] dmaengine: dw: Select only supported masters for ACPI devices

by Andy Shevchenko

From: Serge Semin <fancer.lancer(a)gmail.com> The recently submitted fix-commit revealed a problem in the iDMA 32-bit platform code. Even though the controller supported only a single master the dw_dma_acpi_filter() method hard-coded two master interfaces with IDs 0 and 1. As a result the sanity check implemented in the commit b336268dde75 ("dmaengine: dw: Add peripheral bus width verification") got incorrect interface data width and thus prevented the client drivers from configuring the DMA-channel with the EINVAL error returned. E.g., the next error was printed for the PXA2xx SPI controller driver trying to configure the requested channels: > [ 164.525604] pxa2xx_spi_pci 0000:00:07.1: DMA slave config failed > [ 164.536105] pxa2xx_spi_pci 0000:00:07.1: failed to get DMA TX descriptor > [ 164.543213] spidev spi-SPT0001:00: SPI transfer failed: -16 The problem would have been spotted much earlier if the iDMA 32-bit controller supported more than one master interfaces. But since it supports just a single master and the iDMA 32-bit specific code just ignores the master IDs in the CTLLO preparation method, the issue has been gone unnoticed so far. Fix the problem by specifying the default master ID for both memory and peripheral devices in the driver data. Thus the issue noticed for the iDMA 32-bit controllers will be eliminated and the ACPI-probed DW DMA controllers will be configured with the correct master ID by default. Cc: stable(a)vger.kernel.org Fixes: b336268dde75 ("dmaengine: dw: Add peripheral bus width verification") Fixes: 199244d69458 ("dmaengine: dw: add support of iDMA 32-bit hardware") Reported-by: Ferry Toth <fntoth(a)gmail.com> Closes: https://lore.kernel.org/dmaengine/ZuXbCKUs1iOqFu51@black.fi.intel.com/ Reported-by: Andy Shevchenko <andriy.shevchenko(a)linux.intel.com> Closes: https://lore.kernel.org/dmaengine/ZuXgI-VcHpMgbZ91@black.fi.intel.com/ Co-developed-by: Serge Semin <fancer.lancer(a)gmail.com> Signed-off-by: Serge Semin <fancer.lancer(a)gmail.com> Tested-by: Ferry Toth <fntoth(a)gmail.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko(a)linux.intel.com> --- v4: gathered tag (Ferry), left the code as agreed with Serge and Andy drivers/dma/dw/acpi.c | 6 ++++-- drivers/dma/dw/internal.h | 8 ++++++++ drivers/dma/dw/pci.c | 4 ++-- 3 files changed, 14 insertions(+), 4 deletions(-) diff --git a/drivers/dma/dw/acpi.c b/drivers/dma/dw/acpi.c index c510c109d2c3..b6452fffa657 100644 --- a/drivers/dma/dw/acpi.c +++ b/drivers/dma/dw/acpi.c @@ -8,13 +8,15 @@ static bool dw_dma_acpi_filter(struct dma_chan *chan, void *param) { + struct dw_dma *dw = to_dw_dma(chan->device); + struct dw_dma_chip_pdata *data = dev_get_drvdata(dw->dma.dev); struct acpi_dma_spec *dma_spec = param; struct dw_dma_slave slave = { .dma_dev = dma_spec->dev, .src_id = dma_spec->slave_id, .dst_id = dma_spec->slave_id, - .m_master = 0, - .p_master = 1, + .m_master = data->m_master, + .p_master = data->p_master, }; return dw_dma_filter(chan, &slave); diff --git a/drivers/dma/dw/internal.h b/drivers/dma/dw/internal.h index 563ce73488db..f1bd06a20cd6 100644 --- a/drivers/dma/dw/internal.h +++ b/drivers/dma/dw/internal.h @@ -51,11 +51,15 @@ struct dw_dma_chip_pdata { int (*probe)(struct dw_dma_chip *chip); int (*remove)(struct dw_dma_chip *chip); struct dw_dma_chip *chip; + u8 m_master; + u8 p_master; }; static __maybe_unused const struct dw_dma_chip_pdata dw_dma_chip_pdata = { .probe = dw_dma_probe, .remove = dw_dma_remove, + .m_master = 0, + .p_master = 1, }; static const struct dw_dma_platform_data idma32_pdata = { @@ -72,6 +76,8 @@ static __maybe_unused const struct dw_dma_chip_pdata idma32_chip_pdata = { .pdata = &idma32_pdata, .probe = idma32_dma_probe, .remove = idma32_dma_remove, + .m_master = 0, + .p_master = 0, }; static const struct dw_dma_platform_data xbar_pdata = { @@ -88,6 +94,8 @@ static __maybe_unused const struct dw_dma_chip_pdata xbar_chip_pdata = { .pdata = &xbar_pdata, .probe = idma32_dma_probe, .remove = idma32_dma_remove, + .m_master = 0, + .p_master = 0, }; #endif /* _DMA_DW_INTERNAL_H */ diff --git a/drivers/dma/dw/pci.c b/drivers/dma/dw/pci.c index ad2d4d012cf7..e8a0eb81726a 100644 --- a/drivers/dma/dw/pci.c +++ b/drivers/dma/dw/pci.c @@ -56,10 +56,10 @@ static int dw_pci_probe(struct pci_dev *pdev, const struct pci_device_id *pid) if (ret) return ret; - dw_dma_acpi_controller_register(chip->dw); - pci_set_drvdata(pdev, data); + dw_dma_acpi_controller_register(chip->dw); + return 0; } -- 2.43.0.rc1.1336.g36b5255a03ac

[PATCH net v2] mctp i2c: handle NULL header address

by Matt Johnston

This is a problem for s390x KVM, which explicitly remaps all PMD-mapped THPs to be PTE-mapped in s390_enable_sie()->thp_split_mm(), before starting the VM. For example, starting a VM backed on a file system with large folios supported makes the VM crash when the VM tries accessing such a mapping using KVM. Is it also a problem when the HW disabled THP using TRANSPARENT_HUGEPAGE_UNSUPPORTED? At least on x86 this would be the case without X86_FEATURE_PSE. In the future, we might be able to do better on s390x and only disallow PMD mappings -- what s390x and likely TRANSPARENT_HUGEPAGE_UNSUPPORTED really wants. For now, fix it by essentially performing the same check as would be done in __thp_vma_allowable_orders() or in shmem code, where this works as expected, and disallow PMD mappings, making us fallback to PTE mappings.

[PATCH v2] arm64: dts: mediatek: mt8186-corsola-voltorb: Merge speaker codec nodes

by Chen-Yu Tsai

The Voltorb device uses a speaker codec different from the original Corsola device. When the Voltorb device tree was first added, the new codec was added as a separate node when it should have just replaced the existing one. Merge the two nodes. The only differences are the compatible string and the GPIO line property name. This keeps the device node path for the speaker codec the same across the MT8186 Chromebook line. Also rename the related labels and node names from having rt1019p to speaker codec. Cc: <stable(a)vger.kernel.org> # v6.11+ Signed-off-by: Chen-Yu Tsai <wenst(a)chromium.org> --- This is technically not a fix, but having the same device tree structure in stable kernels would be more consistent for consumers of the device tree. Hence the request for a stable backport.

During testing, it was found that we can get PMD mappings in processes where THP (and more precisely, PMD mappings) are supposed to be disabled. While it works as expected for anon+shmem, the pagecache is the problematic bit. For s390 KVM this currently means that a VM backed by a file located on filesystem with large folio support can crash when KVM tries accessing the problematic page, because the readahead logic might decide to use a PMD-sized THP and faulting it into the page tables will install a PMD mapping, something that s390 KVM cannot tolerate. This might also be a problem with HW that does not support PMD mappings, but I did not try reproducing it. Fix it by respecting the ways to disable THPs when deciding whether we can install a PMD mapping. khugepaged should already be taking care of not collapsing if THPs are effectively disabled for the hw/process/vma. This patch (of 2): Add vma_thp_disabled() and thp_disabled_by_hw() helpers to be shared by shmem_allowable_huge_orders() and __thp_vma_allowable_orders().

[PATCH stable-6.6.x 0/3] ASoC: SOF: ipc4-control: Support for Switch and Enum controls

by Peter Ujfalusi

Hi, This is a backport of [1] series for 6.6.x stable kernel. It is fixing a user reported [2] NULL dereference kernel panic after updating the SOF firmware and topology files. While Meteor Lake is not supported by 6.6 kernel, users might need to be able to use it as a jumping point to update the kernel to a version which is supporting Meteor Lake (6.7+), a kernel panic should be avoided to not block the transition.

Before that commit, both DWC3_GUSB3PIPECTL_SUSPHY and DWC3_GUSB2PHYCFG_SUSPHY bits (hence forth called 2 SUSPHY bits) were being set during core initialization and even during core re-initialization after a system suspend/resume. These bits are required to be set for system suspend/resume to work correctly on AM62 platforms. Since that commit, the 2 SUSPHY bits are not set for DEVICE/OTG mode if gadget driver is not loaded and started. For Host mode, the 2 SUSPHY bits are set before the first system suspend but get cleared at system resume during core re-init and are never set again. This patch resovles these two issues by ensuring the 2 SUSPHY bits are set before system suspend and restored to the original state during system resume.

This condition happens when the following sequence of events occur: - imx_uart_mctrl_check() is called at some point and takes a snapshot of UART control signal status into sport->old_status using imx_uart_get_hwmctrl(). The RTSS/TIOCM_CTS bit is of interest here (*). - DMA transfer occurs, the remote device asserts RTS signal after each byte. The i.MX UART driver recognizes each such RTS signal change, raises an interrupt with USR1 register RTSD bit set, which leads to invocation of __imx_uart_rtsint(), which calls uart_handle_cts_change(). - If the RTS signal is deasserted, uart_handle_cts_change() clears port->hw_stopped and unblocks the port for further data transfers. - If the RTS is asserted, uart_handle_cts_change() sets port->hw_stopped and blocks the port for further data transfers. This may occur as the last interrupt of a transfer, which means port->hw_stopped remains set and the port remains blocked (**). - Any further data transfer attempts will trigger imx_uart_mctrl_check(), which will read current status of UART control signals by calling imx_uart_get_hwmctrl() (***) and compare it with sport->old_status . - If current status differs from sport->old_status for RTS signal, uart_handle_cts_change() is called and possibly unblocks the port by clearing port->hw_stopped . - If current status does not differ from sport->old_status for RTS signal, no action occurs. This may occur in case prior snapshot (*) was taken before any transfer so the RTS is deasserted, current snapshot (***) was taken after a transfer and therefore RTS is deasserted again, which means current status and sport->old_status are identical. In case (**) triggered when RTS got asserted, and made port->hw_stopped set, the port->hw_stopped will remain set because no change on RTS line is recognized by this driver and uart_handle_cts_change() is not called from here to unblock the port->hw_stopped. Update sport->old_status in __imx_uart_rtsint() accordingly to make imx_uart_mctrl_check() detect such RTS change. Note that TIOCM_CAR and TIOCM_RI bits in sport->old_status do not suffer from this problem.

[PATCH RFC v3 00/10] extensible syscalls: CHECK_FIELDS to allow for easier feature detection

by Aleksa Sarai

This is something that I've been thinking about for a while. We had a discussion at LPC 2020 about this[1] but the proposals suggested there never materialised. In short, it is quite difficult for userspace to detect the feature capability of syscalls at runtime. This is something a lot of programs want to do, but they are forced to create elaborate scenarios to try to figure out if a feature is supported without causing damage to the system. For the vast majority of cases, each individual feature also needs to be tested individually (because syscall results are all-or-nothing), so testing even a single syscall's feature set can easily inflate the startup time of programs. This patchset implements the fairly minimal design I proposed in this talk[2] and in some old LKML threads (though I can't find the exact references ATM). The general flow looks like: 1. Userspace will indicate to the kernel that a syscall should a be no-op by setting the top bit of the extensible struct size argument. We will almost certainly never support exabyte sized structs, so the top bits are free for us to use as makeshift flag bits. This is preferable to using the per-syscall flag field inside the structure because seccomp can easily detect the bit in the flag and allow the probe or forcefully return -EEXTSYS_NOOP. 2. The kernel will then fill the provided structure with every valid bit pattern that the current kernel understands. For flags or other bitflag-like fields, this is the set of valid flags or bits. For pointer fields or fields that take an arbitrary value, the field has every bit set (0xFF... to fill the field) to indicate that any value is valid in the field. 3. The syscall then returns -EEXTSYS_NOOP which is an errno that will only ever be used for this purpose (so userspace can be sure that the request succeeded). On older kernels, the syscall will return a different error (usually -E2BIG or -EFAULT) and userspace can do their old-fashioned checks. 4. Userspace can then check which flags and fields are supported by looking at the fields in the returned structure. Flags are checked by doing an AND with the flags field, and field support can checked by comparing to 0. In principle you could just AND the entire structure if you wanted to do this check generically without caring about the structure contents (this is what libraries might consider doing). Userspace can even find out the internal kernel structure size by passing a PAGE_SIZE buffer and seeing how many bytes are non-zero. As with copy_struct_from_user(), this is designed to be forward- and backwards- compatible. This allows programas to get a one-shot understanding of what features a syscall supports without having to do any elaborate setups or tricks to detect support for destructive features. Flags can simply be ANDed to check if they are in the supported set, and fields can just be checked to see if they are non-zero. This patchset is IMHO the simplest way we can add the ability to introspect the feature set of extensible struct (copy_struct_from_user) syscalls. It doesn't preclude the chance of a more generic mechanism being added later. The intended way of using this interface to get feature information looks something like the following (imagine that openat2 has gained a new field and a new flag in the future): static bool openat2_no_automount_supported; static bool openat2_cwd_fd_supported; int check_openat2_support(void) { int err; struct open_how how = {}; err = openat2(AT_FDCWD, ".", &how, CHECK_FIELDS | sizeof(how)); assert(err < 0); switch (errno) { case EFAULT: case E2BIG: /* Old kernel... */ check_support_the_old_way(); break; case EEXTSYS_NOOP: openat2_no_automount_supported = (how.flags & RESOLVE_NO_AUTOMOUNT); openat2_cwd_fd_supported = (how.cwd_fd != 0); break; } } This series adds CHECK_FIELDS support for the following extensible struct syscalls, as they are quite likely to grow flags in the near future: * openat2 * clone3 * mount_setattr [1]: https://lwn.net/Articles/830666/ [2]: https://youtu.be/ggD-eb3yPVs Signed-off-by: Aleksa Sarai <cyphar(a)cyphar.com> --- Changes in v3: - Fix copy_struct_to_user() return values in case of clear_user() failure. - v2: <https://lore.kernel.org/r/20240906-extensible-structs-check_fields-v2-0-0f4…> Changes in v2: - Add CHECK_FIELDS support to mount_setattr(2). - Fix build failure on architectures with custom errno values. - Rework selftests to use the tools/ uAPI headers rather than custom defining EEXTSYS_NOOP. - Make sure we return -EINVAL and -E2BIG for invalid sizes even if CHECK_FIELDS is set, and add some tests for that. - v1: <https://lore.kernel.org/r/20240902-extensible-structs-check_fields-v1-0-545…> --- Aleksa Sarai (10): uaccess: add copy_struct_to_user helper sched_getattr: port to copy_struct_to_user openat2: explicitly return -E2BIG for (usize > PAGE_SIZE) openat2: add CHECK_FIELDS flag to usize argument selftests: openat2: add 0xFF poisoned data after misaligned struct selftests: openat2: add CHECK_FIELDS selftests clone3: add CHECK_FIELDS flag to usize argument selftests: clone3: add CHECK_FIELDS selftests mount_setattr: add CHECK_FIELDS flag to usize argument selftests: mount_setattr: add CHECK_FIELDS selftest arch/alpha/include/uapi/asm/errno.h | 3 + arch/mips/include/uapi/asm/errno.h | 3 + arch/parisc/include/uapi/asm/errno.h | 3 + arch/sparc/include/uapi/asm/errno.h | 3 + fs/namespace.c | 17 ++ fs/open.c | 18 ++ include/linux/uaccess.h | 97 ++++++++ include/uapi/asm-generic/errno.h | 3 + include/uapi/linux/openat2.h | 2 + kernel/fork.c | 30 ++- kernel/sched/syscalls.c | 42 +--- tools/arch/alpha/include/uapi/asm/errno.h | 3 + tools/arch/mips/include/uapi/asm/errno.h | 3 + tools/arch/parisc/include/uapi/asm/errno.h | 3 + tools/arch/sparc/include/uapi/asm/errno.h | 3 + tools/include/uapi/asm-generic/errno.h | 3 + tools/include/uapi/asm-generic/posix_types.h | 101 ++++++++ tools/testing/selftests/clone3/.gitignore | 1 + tools/testing/selftests/clone3/Makefile | 4 +- .../testing/selftests/clone3/clone3_check_fields.c | 264 +++++++++++++++++++++ tools/testing/selftests/mount_setattr/Makefile | 2 +- .../selftests/mount_setattr/mount_setattr_test.c | 53 ++++- tools/testing/selftests/openat2/Makefile | 2 + tools/testing/selftests/openat2/openat2_test.c | 165 ++++++++++++- 24 files changed, 777 insertions(+), 51 deletions(-) --- base-commit: 98f7e32f20d28ec452afb208f9cffc08448a2652 change-id: 20240803-extensible-structs-check_fields-a47e94cef691 Best regards, -- Aleksa Sarai <cyphar(a)cyphar.com>

[PATCH] drm/amd/display: Disable PSR-SU on Parade 08-01 TCON too

by Mario Limonciello

Stuart Hayhurst has found that both at bootup and fullscreen VA-API video is leading to black screens for around 1 second and kernel WARNING [1] traces when calling dmub_psr_enable() with Parade 08-01 TCON. These symptoms all go away with PSR-SU disabled for this TCON, so disable it for now while DMUB traces [2] from the failure can be analyzed and the failure state properly root caused.

[PATCH v2] Bluetooth: Fix type of len in rfcomm_sock_getsockopt{,_old}()

by Andrej Shadura

Commit 9bf4e919ccad worked around an issue introduced after an innocuous optimisation change in LLVM main: > len is defined as an 'int' because it is assigned from > '__user int *optlen'. However, it is clamped against the result of > sizeof(), which has a type of 'size_t' ('unsigned long' for 64-bit > platforms). This is done with min_t() because min() requires compatible > types, which results in both len and the result of sizeof() being casted > to 'unsigned int', meaning len changes signs and the result of sizeof() > is truncated. From there, len is passed to copy_to_user(), which has a > third parameter type of 'unsigned long', so it is widened and changes > signs again. This excessive casting in combination with the KCSAN > instrumentation causes LLVM to fail to eliminate the __bad_copy_from() > call, failing the build. The same issue occurs in rfcomm in functions rfcomm_sock_getsockopt and rfcomm_sock_getsockopt_old. Change the type of len to size_t in both rfcomm_sock_getsockopt and rfcomm_sock_getsockopt_old and replace min_t() with min().

[char-misc-next v3] mei: use kvmalloc for read buffer

by Alexander Usyskin

Read buffer is allocated according to max message size, reported by the firmware and may reach 64K in systems with pxp client. Contiguous 64k allocation may fail under memory pressure.

[PATCH 2/4] mtd: spi-nand: winbond: Fix 512GW, 01GW, 01JW and 02JW ECC information

by Miquel Raynal

These four chips: * W25N512GW * W25N01GW * W25N01JW * W25N02JW all require a single bit of ECC strength and thus feature an on-die Hamming-like ECC engine. There is no point in filling a ->get_status() callback for them because the main ECC status bytes are located in standard places, and retrieving the number of bitflips in case of corrected chunk is both useless and unsupported (if there are bitflips, then there is 1 at most, so no need to query the chip for that). Without this change, a kernel warning triggers every time a bit flips.

[PATCH 5.4.y] erofs: fix lz4 inplace decompression

by Gao Xiang

commit 3c12466b6b7bf1e56f9b32c366a3d83d87afb4de upstream. Currently EROFS can map another compressed buffer for inplace decompression, that was used to handle the cases that some pages of compressed data are actually not in-place I/O. However, like most simple LZ77 algorithms, LZ4 expects the compressed data is arranged at the end of the decompressed buffer and it explicitly uses memmove() to handle overlapping: __________________________________________________________ |_ direction of decompression --> ____ |_ compressed data _| Although EROFS arranges compressed data like this, it typically maps two individual virtual buffers so the relative order is uncertain. Previously, it was hardly observed since LZ4 only uses memmove() for short overlapped literals and x86/arm64 memmove implementations seem to completely cover it up and they don't have this issue. Juhyung reported that EROFS data corruption can be found on a new Intel x86 processor. After some analysis, it seems that recent x86 processors with the new FSRM feature expose this issue with "rep movsb". Let's strictly use the decompressed buffer for lz4 inplace decompression for now. Later, as an useful improvement, we could try to tie up these two buffers together in the correct order.

The root cause of this problem is that in nilfs_find_entry(), which searches for directory entries, ignores errors when loading a directory page/folio via nilfs_get_folio() fails. If the filesystem images is corrupted, and the i_size of the directory inode is large, and the directory page/folio is successfully read but fails the sanity check, for example when it is zero-filled, nilfs_check_folio() may continue to spit out error messages in bursts. Fix this issue by propagating the error to the callers when loading a page/folio fails in nilfs_find_entry().

[PATCH v2 0/2] Fix KASAN crash when using KASAN_VMALLOC

This problem reported by Clement LE GOFFIC manifest when using CONFIG_KASAN_IN_VMALLOC and VMAP_STACK: https://lore.kernel.org/linux-arm-kernel/a1a1d062-f3a2-4d05-9836-3b098de9db… After some analysis it seems we are missing to sync the VMALLOC shadow memory in top level PGD to all CPUs.

This condition happens when the following sequence of events occur: - imx_uart_mctrl_check() is called at some point and takes a snapshot of UART control signal status into sport->old_status using imx_uart_get_hwmctrl(). The RTSS/TIOCM_CTS bit is of interest here (*). - DMA transfer occurs, the remote device asserts RTS signal after each byte. The i.MX UART driver recognizes each such RTS signal change, raises an interrupt with USR1 register RTSD bit set, which leads to invocation of __imx_uart_rtsint(), which calls uart_handle_cts_change(). - If the RTS signal is deasserted, uart_handle_cts_change() clears port->hw_stopped and unblocks the port for further data transfers. - If the RTS is asserted, uart_handle_cts_change() sets port->hw_stopped and blocks the port for further data transfers. This may occur as the last interrupt of a transfer, which means port->hw_stopped remains set and the port remains blocked (**). - Any further data transfer attempts will trigger imx_uart_mctrl_check(), which will read current status of UART control signals by calling imx_uart_get_hwmctrl() (***) and compare it with sport->old_status . - If current status differs from sport->old_status for RTS signal, uart_handle_cts_change() is called and possibly unblocks the port by clearing port->hw_stopped . - If current status does not differ from sport->old_status for RTS signal, no action occurs. This may occur in case prior snapshot (*) was taken before any transfer so the RTS is deasserted, current snapshot (***) was taken after a transfer and therefore RTS is deasserted again, which means current status and sport->old_status are identical. In case (**) triggered when RTS got asserted, and made port->hw_stopped set, the port->hw_stopped will remain set because no change on RTS line is recognized by this driver and uart_handle_cts_change() is not called from here to unblock the port->hw_stopped. Update sport->old_status in __imx_uart_rtsint() accordingly to make imx_uart_mctrl_check() detect such RTS change. Note that TIOCM_CAR and TIOCM_RI bits in sport->old_status do not suffer from this problem.

Before that commit, both DWC3_GUSB3PIPECTL_SUSPHY and DWC3_GUSB2PHYCFG_SUSPHY bits (hence forth called 2 SUSPHY bits) were being set during core initialization and even during core re-initialization after a system suspend/resume. These bits are required to be set for system suspend/resume to work correctly on AM62 platforms. Since that commit, the 2 SUSPHY bits are not set for DEVICE/OTG mode if gadget driver is not loaded and started. For Host mode, the 2 SUSPHY bits are set before the first system suspend but get cleared at system resume during core re-init and are never set again. This patch resovles these two issues by ensuring the 2 SUSPHY bits are set before system suspend and restored to the original state during system resume.

[PATCH] bpf, arm64: Fix address emission with tag-based KASAN enabled

by Peter Collingbourne

When BPF_TRAMP_F_CALL_ORIG is enabled, the address of a bpf_tramp_image struct on the stack is passed during the size calculation pass and an address on the heap is passed during code generation. This may cause a heap buffer overflow if the heap address is tagged because emit_a64_mov_i64() will emit longer code than it did during the size calculation pass. The same problem could occur without tag-based KASAN if one of the 16-bit words of the stack address happened to be all-ones during the size calculation pass. Fix the problem by assuming the worst case (4 instructions) when calculating the size of the bpf_tramp_image address emission.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Treat each completed full size write to /dev/ttyDBC0 as a separate usb transfer. Make sure the size of the TRBs matches the size of the tty write by first queuing as many max packet size TRBs as possible up to the last TRB which will be cut short to match the size of the tty write. This solves an issue where userspace writes several transfers back to back via /dev/ttyDBC0 into a kfifo before dbgtty can find available request to turn that kfifo data into TRBs on the transfer ring. The boundary between transfer was lost as xhci-dbgtty then turned everyting in the kfifo into as many 'max packet size' TRBs as possible. DbC would then send more data to the host than intended for that transfer, causing host to issue a babble error.

[PATCH] ALSA: hda/tas2781: select CRC32 instead of CRC32_SARWATE

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> Fix the kconfig option for the tas2781 HDA driver to select CRC32 rather than CRC32_SARWATE. CRC32_SARWATE is an option from the kconfig 'choice' that selects the specific CRC32 implementation. Selecting a 'choice' option seems to have no effect, but even if it did work, it would be incorrect for a random driver to override the user's choice. CRC32 is the correct option to select for crc32() to be available.

Hi, After upgrading to 6.6.57 I noticed that my IPv6 firewall config failed to load.

The regression is caused by the following commit: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/… More precisely, the bug is in the change below: +#if IS_ENABLED(CONFIG_IP6_NF_IPTABLES) + { + .name = "NFLOG", + .revision = 0, + .family = NFPROTO_IPV4, + .checkentry = nflog_tg_check, + .destroy = nflog_tg_destroy, + .target = nflog_tg, + .targetsize = sizeof(struct xt_nflog_info), + .me = THIS_MODULE, + }, +#endif Replacing NFPROTO_IPV4 with NFPROTO_IPV6 fixed the issue. Looking at the commit, it seems that at least one more target (MARK) may be also impacted: +#if IS_ENABLED(CONFIG_IP6_NF_IPTABLES) + { + .name = "MARK", + .revision = 2, + .family = NFPROTO_IPV4, + .target = mark_tg, + .targetsize = sizeof(struct xt_mark_tginfo2), + .me = THIS_MODULE, + }, +#endif The same errors seem to be present in the main tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… I also suspect other -stable trees may be impacted by the same issue. Best regards, Krzysztof Olędzki

[PATCH] iio: invensense: fix multiple odr switch when FIFO is off

by Jean-Baptiste Maneyrol via B4 Relay

From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol(a)tdk.com> When multiple ODR switch happens during FIFO off, the change could not be taken into account if you get back to previous FIFO on value. For example, if you run sensor buffer at 50Hz, stop, change to 200Hz, then back to 50Hz and restart buffer, data will be timestamped at 200Hz. This due to testing against mult and not new_mult. To prevent this, let's just run apply_odr automatically when FIFO is off. It will also simplify driver code. Update inv_mpu6050 and inv_icm42600 to delete now useless apply_odr.

[PATCH v3] netfilter: xtables: fix a bunch of typos causing some targets to not load on IPv6

To align with the behavior of Legacy SDB mode, the handling of OCS: ABORTED has been changed to match that of OCS_INVALID_COMMAND_STATUS (SDB), with both returning a SCSI result of DID_REQUEUE. Furthermore, the workaround implemented before the SQ cleanup fix can be removed.

SDEV_QUIESCE was set for all LU's scsi_devices by UFS shutdown, and at that time the audio driver was waiting on blk_mq_submit_bio() holding a mutex_lock while reading the fw binary. After that, a deadlock issue occurred while audio driver shutdown was waiting for mutex_unlock of blk_mq_submit_bio(). To solve this, set SDEV_OFFLINE for all LUs except WLUN, so that any I/O that comes down after a UFS shutdown will return an error.

So rq_qos_wake_function() calls wake_up_process(data->task), which calls try_to_wake_up(), which faults in raw_spin_lock_irqsave(&p->pi_lock). p comes from data->task, and data comes from the waitqueue entry, which is stored on the waiter's stack in rq_qos_wait(). Analyzing the core dump with drgn, I found that the waiter had already woken up and moved on to a completely unrelated code path, clobbering what was previously data->task. Meanwhile, the waker was passing the clobbered garbage in data->task to wake_up_process(), leading to the crash. What's happening is that in between rq_qos_wake_function() deleting the waitqueue entry and calling wake_up_process(), rq_qos_wait() is finding that it already got a token and returning. The race looks like this: rq_qos_wait() rq_qos_wake_function() ============================================================== prepare_to_wait_exclusive() data->got_token = true; list_del_init(&curr->entry); if (data.got_token) break; finish_wait(&rqw->wait, &data.wq); ^- returns immediately because list_empty_careful(&wq_entry->entry) is true ... return, go do something else ... wake_up_process(data->task) (NO LONGER VALID!)-^ Normally, finish_wait() is supposed to synchronize against the waker. But, as noted above, it is returning immediately because the waitqueue entry has already been removed from the waitqueue. The bug is that rq_qos_wake_function() is accessing the waitqueue entry AFTER deleting it. Note that autoremove_wake_function() wakes the waiter and THEN deletes the waitqueue entry, which is the proper order. Fix it by swapping the order. We also need to use list_del_init_careful() to match the list_empty_careful() in finish_wait().

[PATCH mm-unstable v1] mm: allow set/clear page_type again

by Yu Zhao

Some page flags (page->flags) were converted to page types (page->page_types). A recent example is PG_hugetlb. From the exclusive writer's perspective, e.g., a thread doing __folio_set_hugetlb(), there is a difference between the page flag and type APIs: the former allows the same non-atomic operation to be repeated whereas the latter does not. For example, calling __folio_set_hugetlb() twice triggers VM_BUG_ON_FOLIO(), since the second call expects the type (PG_hugetlb) not to be set previously. Using add_hugetlb_folio() as an example, it calls __folio_set_hugetlb() in the following error-handling path. And when that happens, it triggers the aforementioned VM_BUG_ON_FOLIO(). if (folio_test_hugetlb(folio)) { rc = hugetlb_vmemmap_restore_folio(h, folio); if (rc) { spin_lock_irq(&hugetlb_lock); add_hugetlb_folio(h, folio, false); ... It is possible to make hugeTLB comply with the new requirements from the page type API. However, a straightforward fix would be to just allow the same page type to be set or cleared again inside the API, to avoid any changes to its callers.

[PATCH v6 5/5] tpm: flush the auth session only when /dev/tpm0 is open

by Jarkko Sakkinen

Instead of flushing and reloading the auth session for every single transaction, keep the session open unless /dev/tpm0 is used.

[PATCH 1/2] KVM: arm64: Don't retire aborted MMIO instruction

by Oliver Upton

Returning an abort to the guest for an unsupported MMIO access is a documented feature of the KVM UAPI. Nevertheless, it's clear that this plumbing has seen limited testing, since userspace can trivially cause a WARN in the MMIO return: WARNING: CPU: 0 PID: 30558 at arch/arm64/include/asm/kvm_emulate.h:536 kvm_handle_mmio_return+0x46c/0x5c4 arch/arm64/include/asm/kvm_emulate.h:536 Call trace: kvm_handle_mmio_return+0x46c/0x5c4 arch/arm64/include/asm/kvm_emulate.h:536 kvm_arch_vcpu_ioctl_run+0x98/0x15b4 arch/arm64/kvm/arm.c:1133 kvm_vcpu_ioctl+0x75c/0xa78 virt/kvm/kvm_main.c:4487 __do_sys_ioctl fs/ioctl.c:51 [inline] __se_sys_ioctl fs/ioctl.c:893 [inline] __arm64_sys_ioctl+0x14c/0x1c8 fs/ioctl.c:893 __invoke_syscall arch/arm64/kernel/syscall.c:35 [inline] invoke_syscall+0x98/0x2b8 arch/arm64/kernel/syscall.c:49 el0_svc_common+0x1e0/0x23c arch/arm64/kernel/syscall.c:132 do_el0_svc+0x48/0x58 arch/arm64/kernel/syscall.c:151 el0_svc+0x38/0x68 arch/arm64/kernel/entry-common.c:712 el0t_64_sync_handler+0x90/0xfc arch/arm64/kernel/entry-common.c:730 el0t_64_sync+0x190/0x194 arch/arm64/kernel/entry.S:598 The splat is complaining that KVM is advancing PC while an exception is pending, i.e. that KVM is retiring the MMIO instruction despite a pending external abort. Womp womp. Fix the glaring UAPI bug by skipping over all the MMIO emulation in case there is a pending synchronous exception. Note that while userspace is capable of pending an asynchronous exception (SError, IRQ, or FIQ), it is still safe to retire the MMIO instruction in this case as (1) they are by definition asynchronous, and (2) KVM relies on hardware support for pending/delivering these exceptions instead of the software state machine for advancing PC.

[PATCH] xhci: Fix Link TRB DMA in command ring stopped completion event

by Faisal Hassan

During the aborting of a command, the software receives a command completion event for the command ring stopped, with the TRB pointing to the next TRB after the aborted command. If the command we abort is located just before the Link TRB in the command ring, then during the 'command ring stopped' completion event, the xHC gives the Link TRB in the event's cmd DMA, which causes a mismatch in handling command completion event. To handle this situation, an additional check has been added to ignore the mismatch error and continue the operation.

[PATCH 0/2] vfs: fstatat, statx: Consistently accept AT_EMPTY_PATH and NULL path

by Xi Ruoyao

Since Linux 6.11 we support AT_EMPTY_PATH and NULL path for fstatat and statx in "some circumstances" mostly for performance and allowing seccomp audition. But to make the API easier to be documented and used, we should just treat AT_EMPTY_PATH and NULL as is AT_EMPTY_PATH and empty string even if there are no performance or seccomp benefits.

[PATCH 3/8] drm/i915/pmu: Fix crash due to use-after-free

by Lucas De Marchi

When an i915 PMU counter is enabled and the driver is then unbound, the PMU will be unregistered via perf_pmu_unregister(), however the event will still be alive. i915 currently tries to deal with this situation by: a) Marking the pmu as "closed" and shortcut the calls from perf b) Taking a reference from i915, that is put back when the event is destroyed. c) Setting event_init to NULL to avoid any further event (a) is ugly, but may be left as is since it protects not trying to access the HW that is now gone. Unless a pmu driver can call perf_pmu_unregister() and not receive any more calls, it's a necessary ugliness. (b) doesn't really work: when the event is destroyed and the i915 ref is put it may free the i915 object, that contains the pmu, not only the event. After event->destroy() callback, perf still expects the pmu object to be alive. Instead of pigging back on the event->destroy() to take and put the device reference, implement the new get()/put() on the pmu object for that purpose. (c) is only done to have a flag to avoid some function entrypoints when pmu is unregistered.

[PATCH 6.11.y] mm: vmscan.c: fix OOM on swap stress test

[ Upstream commit 0885ef4705607936fc36a38fd74356e1c465b023 ] I found a regression on mm-unstable during my swap stress test, using tmpfs to compile linux.

This reverts the change and replaces the fix for wp-fork-with-event with the original use of atomic_bool. This patch (of 3): This reverts commit e142cc87ac4ec618f2ccf5f68aedcd6e28a59d9d. fork_event_consumer may be called by other tests that do not initialize the pthread_barrier, so this approach is not correct.

[PATCH v3 1/1] nfsd: fix race between laundromat and free_stateid

by Olga Kornievskaia

There is a race between laundromat handling of revoked delegations and a client sending free_stateid operation. Laundromat thread finds that delegation has expired and needs to be revoked so it marks the delegation stid revoked and it puts it on a reaper list but then it unlock the state lock and the actual delegation revocation happens without the lock. Once the stid is marked revoked a racing free_stateid processing thread does the following (1) it calls list_del_init() which removes it from the reaper list and (2) frees the delegation stid structure. The laundromat thread ends up not calling the revoke_delegation() function for this particular delegation but that means it will no release the lock lease that exists on the file. Now, a new open for this file comes in and ends up finding that lease list isn't empty and calls nfsd_breaker_owns_lease() which ends up trying to derefence a freed delegation stateid. Leading to the followint use-after-free KASAN warning: kernel: ================================================================== kernel: BUG: KASAN: slab-use-after-free in nfsd_breaker_owns_lease+0x140/0x160 [nfsd] kernel: Read of size 8 at addr ffff0000e73cd0c8 by task nfsd/6205 kernel: kernel: CPU: 2 UID: 0 PID: 6205 Comm: nfsd Kdump: loaded Not tainted 6.11.0-rc7+ #9 kernel: Hardware name: Apple Inc.

First to make sure, that once the stid is marked revoked, it is not removed by the nfsd4_free_stateid(), the laundromat take a reference on the stateid. Then, coordinating whether the stid has been put on the cl_revoked list or we are processing FREE_STATEID and need to make sure to remove it from the list, each check that state and act accordingly. If laundromat has added to the cl_revoke list before the arrival of FREE_STATEID, then nfsd4_free_stateid() knows to remove it from the list. If nfsd4_free_stateid() finds that operations arrived before laundromat has placed it on cl_revoke list, it marks the state freed and then laundromat will no longer add it to the list. Also, for nfsd4_delegreturn() when looking for the specified stid, we need to access stid that are marked removed or freeable, it means the laundromat has started processing it but hasn't finished and this delegreturn needs to return nfserr_deleg_revoked and not nfserr_bad_stateid. The latter will not trigger a FREE_STATEID and the lack of it will leave this stid on the cl_revoked list indefinitely.

[PATCH] resource,kexec: walk_system_ram_res_rev must retain resource flags

by Gregory Price

walk_system_ram_res_rev() erroneously discards resource flags when passing the information to the callback. This causes systems with IORESOURCE_SYSRAM_DRIVER_MANAGED memory to have these resources selected during kexec to store kexec buffers if that memory happens to be at placed above normal system ram.

[RFC][PATCH] mm: Split locks in remap_file_pages()

by Roberto Sassu

From: "Kirill A. Shutemov" <kirill.shutemov(a)linux.intel.com> Commit ea7e2d5e49c0 ("mm: call the security_mmap_file() LSM hook in remap_file_pages()") fixed a security issue, it added an LSM check when trying to remap file pages, so that LSMs have the opportunity to evaluate such action like for other memory operations such as mmap() and mprotect(). However, that commit called security_mmap_file() inside the mmap_lock lock, while the other calls do it before taking the lock, after commit 8b3ec6814c83 ("take security_mmap_file() outside of ->mmap_sem"). This caused lock inversion issue with IMA which was taking the mmap_lock and i_mutex lock in the opposite way when the remap_file_pages() system call was called. Solve the issue by splitting the critical region in remap_file_pages() in two regions: the first takes a read lock of mmap_lock and retrieves the VMA and the file associated, and calculate the 'prot' and 'flags' variable; the second takes a write lock on mmap_lock, checks that the VMA flags and the VMA file descriptor are the same as the ones obtained in the first critical region (otherwise the system call fails), and calls do_mmap(). In between, after releasing the read lock and taking the write lock, call security_mmap_file(), and solve the lock inversion issue.

[PATCH v3] comedi: Flush partial mappings in error case

by Jann Horn

If some remap_pfn_range() calls succeeded before one failed, we still have buffer pages mapped into the userspace page tables when we drop the buffer reference with comedi_buf_map_put(bm). The userspace mappings are only cleaned up later in the mmap error path. Fix it by explicitly flushing all mappings in our VMA on the error path. See commit 79a61cc3fc04 ("mm: avoid leaving partial pfn mappings around in error case").

[PATCH RESEND] vdpa: solidrun: Fix UB bug with devres

by Philipp Stanner

In psnet_open_pf_bar() and snet_open_vf_bar() a string later passed to pcim_iomap_regions() is placed on the stack. Neither pcim_iomap_regions() nor the functions it calls copy that string. Should the string later ever be used, this, consequently, causes undefined behavior since the stack frame will by then have disappeared. Fix the bug by allocating the strings on the heap through devm_kasprintf(). Cc: stable(a)vger.kernel.org # v6.3 Fixes: 51a8f9d7f587 ("virtio: vdpa: new SolidNET DPU driver.")

[PATCH 5.10] gfs2: Fix potential glock use-after-free on unmount

by He Zhe

From: Andreas Gruenbacher <agruenba(a)redhat.com> commit 0636b34b44589b142700ac137b5f69802cfe2e37 upstream. When a DLM lockspace is released and there ares still locks in that lockspace, DLM will unlock those locks automatically. Commit fb6791d100d1b started exploiting this behavior to speed up filesystem unmount: gfs2 would simply free glocks it didn't want to unlock and then release the lockspace. This didn't take the bast callbacks for asynchronous lock contention notifications into account, which remain active until until a lock is unlocked or its lockspace is released. To prevent those callbacks from accessing deallocated objects, put the glocks that should not be unlocked on the sd_dead_glocks list, release the lockspace, and only then free those glocks. As an additional measure, ignore unexpected ast and bast callbacks if the receiving glock is dead.

[PATCH v2] remoteproc: qcom_q6v5_pas: disable auto boot for wpss

by Balaji Pothunoori

Currently, the rproc "atomic_t power" variable is incremented during: a. WPSS rproc auto boot. b. AHB power on for ath11k. During AHB power off (rmmod ath11k_ahb.ko), rproc_shutdown fails to unload the WPSS firmware because the rproc->power value is '2', causing the atomic_dec_and_test(&rproc->power) condition to fail. Consequently, during AHB power on (insmod ath11k_ahb.ko), QMI_WLANFW_HOST_CAP_REQ_V01 fails due to the host and firmware QMI states being out of sync.

Wang, the splat is false positive, but the code path leading to the report is an unexpected one: a client is attempting an MPC handshake towards the in-kernel listener created by the in-kernel PM for a port based signal endpoint. Such connection will be never accepted; many of them can make the listener queue full and preventing the creation of MPJ subflow via such listener - its intended role. Explicitly detect this scenario at initial-syn time and drop the incoming MPC request.

[PATCH 5.10 5.15 1/3] io_uring/sqpoll: do not allow pinning outside of cpuset

by Felix Moessbauer

commit f011c9cf04c06f16b24f583d313d3c012e589e50 upstream. The submit queue polling threads are userland threads that just never exit to the userland. When creating the thread with IORING_SETUP_SQ_AFF, the affinity of the poller thread is set to the cpu specified in sq_thread_cpu. However, this CPU can be outside of the cpuset defined by the cgroup cpuset controller. This violates the rules defined by the cpuset controller and is a potential issue for realtime applications. In b7ed6d8ffd6 we fixed the default affinity of the poller thread, in case no explicit pinning is required by inheriting the one of the creating task. In case of explicit pinning, the check is more complicated, as also a cpu outside of the parent cpumask is allowed. We implemented this by using cpuset_cpus_allowed (that has support for cgroup cpusets) and testing if the requested cpu is in the set.

[PATCH 5.10 0/1] wifi: rtl8xxxu: Fix the error handling of the probe function

by Daniil Dulov

Svacer reports a NULL-pointer dereference in rtl8xxxu_probe(). After having been compared to a NULL value, pointer hw is passed as 1st parameter in call to ieee80211_free_hw(), where it is dereferenced. The problem is present in 5.10 stable release and can be fixed by the following upstream patch that can be cleanly applied to 5.10 branch.

The repro enables pmtu on the loopback device, leading to tcp_mtu_probe() generating very large probe packets. tcp_can_coalesce_send_queue_head() currently does not check for mptcp-level invariants, and allowed the creation of cross-DSS probes, leading to the mentioned corruption. Address the issue teaching tcp_can_coalesce_send_queue_head() about mptcp using the tcp_skb_can_collapse(), also reducing the code duplication.

[PATCH 6.1.y 5.15.y] drm/shmem-helper: Fix BUG_ON() on mmap(PROT_WRITE, MAP_PRIVATE)

by Sherry Yang

From: "Wachowski, Karol" <karol.wachowski(a)intel.com> commit 39bc27bd688066a63e56f7f64ad34fae03fbe3b8 upstream. Lack of check for copy-on-write (COW) mapping in drm_gem_shmem_mmap allows users to call mmap with PROT_WRITE and MAP_PRIVATE flag causing a kernel panic due to BUG_ON in vmf_insert_pfn_prot: BUG_ON((vma->vm_flags & VM_PFNMAP) && is_cow_mapping(vma->vm_flags)); Return -EINVAL early if COW mapping is detected. This bug affects all drm drivers using default shmem helpers.

[PATCH 5.15, 5.10, 5.4, 4.19 1/1] KVM: Fix a data race on last_boosted_vcpu in kvm_vcpu_on_spin()

There has been a nasty yet subtle maple tree corruption bug that appears to have been in existence since the inception of the algorithm. This bug seems far more likely to happen since commit f8d112a4e657 ("mm/mmap: avoid zeroing vma tree in mmap_region()"), which is the point at which reports started to be submitted concerning this bug. We were made definitely aware of the bug thanks to the kind efforts of Bert Karwatzki who helped enormously in my being able to track this down and identify the cause of it. The bug arises when an attempt is made to perform a spanning store across two leaf nodes, where the right leaf node is the rightmost child of the shared parent, AND the store completely consumes the right-mode node. This results in mas_wr_spanning_store() mitakenly duplicating the new and existing entries at the maximum pivot within the range, and thus maple tree corruption. The fix patch corrects this by detecting this scenario and disallowing the mistaken duplicate copy. The fix patch commit message goes into great detail as to how this occurs. This series also includes a test which reliably reproduces the issue, and asserts that the fix works correctly. Bert has kindly tested the fix and confirmed it resolved his issues. Also Mikhail Gavrilov kindly reported what appears to be precisely the same bug, which this fix should also resolve. This patch (of 2): There has been a subtle bug present in the maple tree implementation from its inception. This arises from how stores are performed - when a store occurs, it will overwrite overlapping ranges and adjust the tree as necessary to accommodate this. A range may always ultimately span two leaf nodes. In this instance we walk the two leaf nodes, determine which elements are not overwritten to the left and to the right of the start and end of the ranges respectively and then rebalance the tree to contain these entries and the newly inserted one. This kind of store is dubbed a 'spanning store' and is implemented by mas_wr_spanning_store(). In order to reach this stage, mas_store_gfp() invokes mas_wr_preallocate(), mas_wr_store_type() and mas_wr_walk() in turn to walk the tree and update the object (mas) to traverse to the location where the write should be performed, determining its store type. When a spanning store is required, this function returns false stopping at the parent node which contains the target range, and mas_wr_store_type() marks the mas->store_type as wr_spanning_store to denote this fact. When we go to perform the store in mas_wr_spanning_store(), we first determine the elements AFTER the END of the range we wish to store (that is, to the right of the entry to be inserted) - we do this by walking to the NEXT pivot in the tree (i.e. r_mas.last + 1), starting at the node we have just determined contains the range over which we intend to write. We then turn our attention to the entries to the left of the entry we are inserting, whose state is represented by l_mas, and copy these into a 'big node', which is a special node which contains enough slots to contain two leaf node's worth of data. We then copy the entry we wish to store immediately after this - the copy and the insertion of the new entry is performed by mas_store_b_node(). After this we copy the elements to the right of the end of the range which we are inserting, if we have not exceeded the length of the node (i.e. r_mas.offset <= r_mas.end). Herein lies the bug - under very specific circumstances, this logic can break and corrupt the maple tree. Consider the following tree: Height 0 Root Node / \ pivot = 0xffff / \ pivot = ULONG_MAX / \ 1 A [-----] ... / \ pivot = 0x4fff / \ pivot = 0xffff / \ 2 (LEAVES) B [-----] [-----] C ^--- Last pivot 0xffff. Now imagine we wish to store an entry in the range [0x4000, 0xffff] (note that all ranges expressed in maple tree code are inclusive): 1. mas_store_gfp() descends the tree, finds node A at <=0xffff, then determines that this is a spanning store across nodes B and C. The mas state is set such that the current node from which we traverse further is node A. 2. In mas_wr_spanning_store() we try to find elements to the right of pivot 0xffff by searching for an index of 0x10000: - mas_wr_walk_index() invokes mas_wr_walk_descend() and mas_wr_node_walk() in turn. - mas_wr_node_walk() loops over entries in node A until EITHER it finds an entry whose pivot equals or exceeds 0x10000 OR it reaches the final entry. - Since no entry has a pivot equal to or exceeding 0x10000, pivot 0xffff is selected, leading to node C. - mas_wr_walk_traverse() resets the mas state to traverse node C. We loop around and invoke mas_wr_walk_descend() and mas_wr_node_walk() in turn once again. - Again, we reach the last entry in node C, which has a pivot of 0xffff. 3. We then copy the elements to the left of 0x4000 in node B to the big node via mas_store_b_node(), and insert the new [0x4000, 0xffff] entry too. 4. We determine whether we have any entries to copy from the right of the end of the range via - and with r_mas set up at the entry at pivot 0xffff, r_mas.offset <= r_mas.end, and then we DUPLICATE the entry at pivot 0xffff. 5. BUG! The maple tree is corrupted with a duplicate entry. This requires a very specific set of circumstances - we must be spanning the last element in a leaf node, which is the last element in the parent node. spanning store across two leaf nodes with a range that ends at that shared pivot. A potential solution to this problem would simply be to reset the walk each time we traverse r_mas, however given the rarity of this situation it seems that would be rather inefficient. Instead, this patch detects if the right hand node is populated, i.e. has anything we need to copy. We do so by only copying elements from the right of the entry being inserted when the maximum value present exceeds the last, rather than basing this on offset position. The patch also updates some comments and eliminates the unused bool return value in mas_wr_walk_index(). The work performed in commit f8d112a4e657 ("mm/mmap: avoid zeroing vma tree in mmap_region()") seems to have made the probability of this event much more likely, which is the point at which reports started to be submitted concerning this bug. The motivation for this change arose from Bert Karwatzki's report of encountering mm instability after the release of kernel v6.12-rc1 which, after the use of CONFIG_DEBUG_VM_MAPLE_TREE and similar configuration options, was identified as maple tree corruption. After Bert very generously provided his time and ability to reproduce this event consistently, I was able to finally identify that the issue discussed in this commit message was occurring for him.

[PATCH 2/4] xhci: Mitigate failed set dequeue pointer commands

by Mathias Nyman

Avoid xHC host from processing a cancelled URB by always turning cancelled URB TDs into no-op TRBs before queuing a 'Set TR Deq' command. If the command fails then xHC will start processing the cancelled TD instead of skipping it once endpoint is restarted, causing issues like Babble error. This is not a complete solution as a failed 'Set TR Deq' command does not guarantee xHC TRB caches are cleared.

[PATCH 5.10 0/1] iommu/amd: Prepare for multiple DMA domain types

by Daniil Dulov

Svacer reports possible dereference of a NULL-pointer in amd_iommu_probe_finalize(). The problem is present in 5.10 stable release and can be fixed by the following upstream patch. In order to apply this patch, the incoming changes had to be manually accepted. This action was necessary due to some differences in the code of amd_iommu_probe_finalize() of the upstream version and 5.10 version of the kernel.

[PATCH v2 2/7] serial: qcom-geni: fix shutdown race

by Johan Hovold

A commit adding back the stopping of tx on port shutdown failed to add back the locking which had also been removed by commit e83766334f96 ("tty: serial: qcom_geni_serial: No need to stop tx/rx on UART shutdown"). Holding the port lock is needed to serialise against the console code, which may update the interrupt enable register and access the port state. Fixes: d8aca2f96813 ("tty: serial: qcom-geni-serial: stop operations in progress at shutdown") Fixes: 947cc4ecc06c ("serial: qcom-geni: fix soft lockup on sw flow control and suspend") Cc: stable(a)vger.kernel.org # 6.3 Cc: Bartosz Golaszewski <bartosz.golaszewski(a)linaro.org> Signed-off-by: Johan Hovold <johan+linaro(a)kernel.org> --- drivers/tty/serial/qcom_geni_serial.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/tty/serial/qcom_geni_serial.c b/drivers/tty/serial/qcom_geni_serial.c index 9ea6bd09e665..b6a8729cee6d 100644 --- a/drivers/tty/serial/qcom_geni_serial.c +++ b/drivers/tty/serial/qcom_geni_serial.c @@ -1096,10 +1096,12 @@ static void qcom_geni_serial_shutdown(struct uart_port *uport) { disable_irq(uport->irq); + uart_port_lock_irq(uport); qcom_geni_serial_stop_tx(uport); qcom_geni_serial_stop_rx(uport); qcom_geni_serial_cancel_tx_cmd(uport); + uart_port_unlock_irq(uport); } static void qcom_geni_serial_flush_buffer(struct uart_port *uport) -- 2.45.2

There has been a nasty yet subtle maple tree corruption bug that appears to have been in existence since the inception of the algorithm. This bug seems far more likely to happen since commit f8d112a4e657 ("mm/mmap: avoid zeroing vma tree in mmap_region()"), which is the point at which reports started to be submitted concerning this bug. We were made definitely aware of the bug thanks to the kind efforts of Bert Karwatzki who helped enormously in my being able to track this down and identify the cause of it. The bug arises when an attempt is made to perform a spanning store across two leaf nodes, where the right leaf node is the rightmost child of the shared parent, AND the store completely consumes the right-mode node. This results in mas_wr_spanning_store() mitakenly duplicating the new and existing entries at the maximum pivot within the range, and thus maple tree corruption. The fix patch corrects this by detecting this scenario and disallowing the mistaken duplicate copy. The fix patch commit message goes into great detail as to how this occurs. This series also includes a test which reliably reproduces the issue, and asserts that the fix works correctly. Bert has kindly tested the fix and confirmed it resolved his issues. Also Mikhail Gavrilov kindly reported what appears to be precisely the same bug, which this fix should also resolve. This patch (of 2): There has been a subtle bug present in the maple tree implementation from its inception. This arises from how stores are performed - when a store occurs, it will overwrite overlapping ranges and adjust the tree as necessary to accommodate this. A range may always ultimately span two leaf nodes. In this instance we walk the two leaf nodes, determine which elements are not overwritten to the left and to the right of the start and end of the ranges respectively and then rebalance the tree to contain these entries and the newly inserted one. This kind of store is dubbed a 'spanning store' and is implemented by mas_wr_spanning_store(). In order to reach this stage, mas_store_gfp() invokes mas_wr_preallocate(), mas_wr_store_type() and mas_wr_walk() in turn to walk the tree and update the object (mas) to traverse to the location where the write should be performed, determining its store type. When a spanning store is required, this function returns false stopping at the parent node which contains the target range, and mas_wr_store_type() marks the mas->store_type as wr_spanning_store to denote this fact. When we go to perform the store in mas_wr_spanning_store(), we first determine the elements AFTER the END of the range we wish to store (that is, to the right of the entry to be inserted) - we do this by walking to the NEXT pivot in the tree (i.e. r_mas.last + 1), starting at the node we have just determined contains the range over which we intend to write. We then turn our attention to the entries to the left of the entry we are inserting, whose state is represented by l_mas, and copy these into a 'big node', which is a special node which contains enough slots to contain two leaf node's worth of data. We then copy the entry we wish to store immediately after this - the copy and the insertion of the new entry is performed by mas_store_b_node(). After this we copy the elements to the right of the end of the range which we are inserting, if we have not exceeded the length of the node (i.e. r_mas.offset <= r_mas.end). Herein lies the bug - under very specific circumstances, this logic can break and corrupt the maple tree. Consider the following tree: Height 0 Root Node / \ pivot = 0xffff / \ pivot = ULONG_MAX / \ 1 A [-----] ... / \ pivot = 0x4fff / \ pivot = 0xffff / \ 2 (LEAVES) B [-----] [-----] C ^--- Last pivot 0xffff. Now imagine we wish to store an entry in the range [0x4000, 0xffff] (note that all ranges expressed in maple tree code are inclusive): 1. mas_store_gfp() descends the tree, finds node A at <=0xffff, then determines that this is a spanning store across nodes B and C. The mas state is set such that the current node from which we traverse further is node A. 2. In mas_wr_spanning_store() we try to find elements to the right of pivot 0xffff by searching for an index of 0x10000: - mas_wr_walk_index() invokes mas_wr_walk_descend() and mas_wr_node_walk() in turn. - mas_wr_node_walk() loops over entries in node A until EITHER it finds an entry whose pivot equals or exceeds 0x10000 OR it reaches the final entry. - Since no entry has a pivot equal to or exceeding 0x10000, pivot 0xffff is selected, leading to node C. - mas_wr_walk_traverse() resets the mas state to traverse node C. We loop around and invoke mas_wr_walk_descend() and mas_wr_node_walk() in turn once again. - Again, we reach the last entry in node C, which has a pivot of 0xffff. 3. We then copy the elements to the left of 0x4000 in node B to the big node via mas_store_b_node(), and insert the new [0x4000, 0xffff] entry too. 4. We determine whether we have any entries to copy from the right of the end of the range via - and with r_mas set up at the entry at pivot 0xffff, r_mas.offset <= r_mas.end, and then we DUPLICATE the entry at pivot 0xffff. 5. BUG! The maple tree is corrupted with a duplicate entry. This requires a very specific set of circumstances - we must be spanning the last element in a leaf node, which is the last element in the parent node. spanning store across two leaf nodes with a range that ends at that shared pivot. A potential solution to this problem would simply be to reset the walk each time we traverse r_mas, however given the rarity of this situation it seems that would be rather inefficient. Instead, this patch detects if the right hand node is populated, i.e. has anything we need to copy. We do so by only copying elements from the right of the entry being inserted when the maximum value present exceeds the last, rather than basing this on offset position. The patch also updates some comments and eliminates the unused bool return value in mas_wr_walk_index(). The work performed in commit f8d112a4e657 ("mm/mmap: avoid zeroing vma tree in mmap_region()") seems to have made the probability of this event much more likely, which is the point at which reports started to be submitted concerning this bug. The motivation for this change arose from Bert Karwatzki's report of encountering mm instability after the release of kernel v6.12-rc1 which, after the use of CONFIG_DEBUG_VM_MAPLE_TREE and similar configuration options, was identified as maple tree corruption. After Bert very generously provided his time and ability to reproduce this event consistently, I was able to finally identify that the issue discussed in this commit message was occurring for him.

[PATCH 5.15.y 5.10.y 5.4.y] wifi: mac80211: fix potential key use-after-free

by Sherry Yang

From: Johannes Berg <johannes.berg(a)intel.com> [ Upstream commit 31db78a4923ef5e2008f2eed321811ca79e7f71b ] When ieee80211_key_link() is called by ieee80211_gtk_rekey_add() but returns 0 due to KRACK protection (identical key reinstall), ieee80211_gtk_rekey_add() will still return a pointer into the key, in a potential use-after-free. This normally doesn't happen since it's only called by iwlwifi in case of WoWLAN rekey offload which has its own KRACK protection, but still better to fix, do that by returning an error code and converting that to success on the cfg80211 boundary only, leaving the error for bad callers of ieee80211_gtk_rekey_add().

[PATCH 6.1.y] nvme: fix metadata handling in nvme-passthrough

by Puranjay Mohan

[ Upstream commit 7c2fd76048e95dd267055b5f5e0a48e6e7c81fd9 ] On an NVMe namespace that does not support metadata, it is possible to send an IO command with metadata through io-passthru. This allows issues like [1] to trigger in the completion code path. nvme_map_user_request() doesn't check if the namespace supports metadata before sending it forward. It also allows admin commands with metadata to be processed as it ignores metadata when bdev == NULL and may report success. Reject an IO command with metadata when the NVMe namespace doesn't support it and reject an admin command if it has metadata.

[PATCH stable 6.1 0/2] devlink: Fix RCU stall when unregistering a devlink instance

by Ido Schimmel

Upstream commit c2368b19807a ("net: devlink: introduce "unregistering" mark and use it during devlinks iteration") in v6.0 introduced a race when unregistering a devlink instance that can result in RCU stalls and in the system completely locking up. Exact details and reproducer can be found here [1]. The bug was inadvertently fixed in v6.3 by upstream commit d77278196441 ("devlink: bump the instance index directly when iterating"). This patchset fixes the bug by backporting the second commit and a related dependency from v6.3 to v6.1.y while adjusting them to the devlink file structure in v6.1.y (net/devlink/{core.c,devl_internal.h} -> net/devlink/leftover.c). Tested by running the devlink tests under tools/testing/selftests/drivers/net/netdevsim/ and the reproducer mentioned in [1].

This is the case for example on some arm64 configurations, where marking 4k PTEs in the direct map not present can only be done if the direct map is set up at 4k granularity in the first place (as ARM's break-before-make semantics do not easily allow breaking apart large/gigantic pages). More precisely, on arm64 systems with !can_set_direct_map(), set_direct_map_invalid_noflush() is a no-op, however it returns success (0) instead of an error. This means that memfd_secret will seemingly "work" (e.g. syscall succeeds, you can mmap the fd and fault in pages), but it does not actually achieve its goal of removing its memory from the direct map. Note that with this patch, memfd_secret() will start erroring on systems where can_set_direct_map() returns false (arm64 with CONFIG_RODATA_FULL_DEFAULT_ENABLED=n, CONFIG_DEBUG_PAGEALLOC=n and CONFIG_KFENCE=n), but that still seems better than the current silent failure. Since CONFIG_RODATA_FULL_DEFAULT_ENABLED defaults to 'y', most arm64 systems actually have a working memfd_secret() and aren't be affected. From going through the iterations of the original memfd_secret patch series, it seems that disabling the syscall in these scenarios was the intended behavior [1] (preferred over having set_direct_map_invalid_noflush return an error as that would result in SIGBUSes at page-fault time), however the check for it got dropped between v16 [2] and v17 [3], when secretmem moved away from CMA allocations.

This is a problem for s390x KVM, which explicitly remaps all PMD-mapped THPs to be PTE-mapped in s390_enable_sie()->thp_split_mm(), before starting the VM. For example, starting a VM backed on a file system with large folios supported makes the VM crash when the VM tries accessing such a mapping using KVM. Is it also a problem when the HW disabled THP using TRANSPARENT_HUGEPAGE_UNSUPPORTED? At least on x86 this would be the case without X86_FEATURE_PSE. In the future, we might be able to do better on s390x and only disallow PMD mappings -- what s390x and likely TRANSPARENT_HUGEPAGE_UNSUPPORTED really wants. For now, fix it by essentially performing the same check as would be done in __thp_vma_allowable_orders() or in shmem code, where this works as expected, and disallow PMD mappings, making us fallback to PTE mappings.
