[PATCH] drm/amdgpu: Raven: don't allow mixing GTT and VRAM

by Brian Geffon

Commit 81d0bcf99009 ("drm/amdgpu: make display pinning more flexible (v2)") allowed for newer ASICs to mix GTT and VRAM, this change also noted that some older boards, such as Stoney and Carrizo do not support this. It appears that at least one additional ASIC does not support this which is Raven. We observed this issue when migrating a device from a 5.4 to 6.6 kernel and have confirmed that Raven also needs to be excluded from mixing GTT and VRAM.

[PATCH 6.1] HID: mcp2221: Set driver data before I2C adapter add

by Sumanth Gavini

The process of adding an I2C adapter can invoke I2C accesses on that new adapter (see i2c_detect()). Ensure we have set the adapter's driver data to avoid null pointer dereferences in the xfer functions during the adapter add. This has been noted in the past and the same fix proposed but not completed.

[PATCH] i2c: qup: jump out of the loop in case of timeout

by Yang Xiwen via B4 Relay

From: Yang Xiwen <forbidden405(a)outlook.com> Original logic only sets the return value but doesn't jump out of the loop if the bus is kept active by a client. This is not expected. A malicious or buggy i2c client can hang the kernel in this case and should be avoided. This is observed during a long time test with a PCA953x GPIO extender. Fix it by changing the logic to not only sets the return value, but also jumps out of the loop and return to the caller with -ETIMEDOUT.

[PATCH 1/7] drm/i915/dp: Fix 2.7 Gbps DP_LINK_BW value on g4x

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> On g4x we currently use the 96MHz non-SSC refclk, which can't actually generate an exact 2.7 Gbps link rate. In practice we end up with 2.688 Gbps which seems to be close enough to actually work, but link training is currently failing due to miscalculating the DP_LINK_BW value (we calcualte it directly from port_clock which reflects the actual PLL outpout frequency). Ideas how to fix this: - nudge port_clock back up to 270000 during PLL computation/readout - track port_clock and the nominal link rate separately so they might differ a bit - switch to the 100MHz refclk, but that one should be SSC so perhaps not something we want While we ponder about a better solution apply some band aid to the immediate issue of miscalculated DP_LINK_BW value. With this I can again use 2.7 Gbps link rate on g4x.

[PATCH 1/2] nvmem: layouts: u-boot-env: remove crc32 endianness conversion

by srini＠kernel.org

From: "Michael C. Pratt" <mcpratt(a)pm.me> On 11 Oct 2022, it was reported that the crc32 verification of the u-boot environment failed only on big-endian systems for the u-boot-env nvmem layout driver with the following error. Invalid calculated CRC32: 0x88cd6f09 (expected: 0x096fcd88) This problem has been present since the driver was introduced, and before it was made into a layout driver. The suggested fix at the time was to use further endianness conversion macros in order to have both the stored and calculated crc32 values to compare always represented in the system's endianness. This was not accepted due to sparse warnings and some disagreement on how to handle the situation. Later on in a newer revision of the patch, it was proposed to use cpu_to_le32() for both values to compare instead of le32_to_cpu() and store the values as __le32 type to remove compilation errors. The necessity of this is based on the assumption that the use of crc32() requires endianness conversion because the algorithm uses little-endian, however, this does not prove to be the case and the issue is unrelated. Upon inspecting the current kernel code, there already is an existing use of le32_to_cpu() in this driver, which suggests there already is special handling for big-endian systems, however, it is big-endian systems that have the problem. This, being the only functional difference between architectures in the driver combined with the fact that the suggested fix was to use the exact same endianness conversion for the values brings up the possibility that it was not necessary to begin with, as the same endianness conversion for two values expected to be the same is expected to be equivalent to no conversion at all. After inspecting the u-boot environment of devices of both endianness and trying to remove the existing endianness conversion, the problem is resolved in an equivalent way as the other suggested fixes. Ultimately, it seems that u-boot is agnostic to endianness at least for the purpose of environment variables. In other words, u-boot reads and writes the stored crc32 value with the same endianness that the crc32 value is calculated with in whichever endianness a certain architecture runs on. Therefore, the u-boot-env driver does not need to convert endianness. Remove the usage of endianness macros in the u-boot-env driver, and change the type of local variables to maintain the same return type. If there is a special situation in the case of endianness, it would be a corner case and should be handled by a unique "compatible". Even though it is not necessary to use endianness conversion macros here, it may be useful to use them in the future for consistent error printing.

Backport a5a441ae283d ("ice/ptp: fix crosstimestamp reporting")

by Markus Blöchl

Hi Greg, please consider backporting a5a441ae283d ("ice/ptp: fix crosstimestamp reporting") into linux-6.12.y It fixes a regression from the series around d4bea547ebb57 ("ice/ptp: Remove convert_art_to_tsc()") which affected multiple drivers and occasionally caused phc2sys to fail on ioctl(fd, PTP_SYS_OFFSET_PRECISE, ...). This was the initial fix for ice but apparently tagging it for stable was forgotten during submission. A similar fix for e1000e can be found here: Link: https://lore.kernel.org/lkml/20250709-e1000e_crossts-v2-1-2aae94384c59@bloc… The hunk was moved around slightly in the upstream commit 92456e795ac6 ("ice: Add unified ice_capture_crosststamp"). Let me know if you therefore want a separate patch, I just didn't want to to steal the credits here. Thanks a lot! Markus --

[PATCH net 3/5] rxrpc: Fix notification vs call-release vs recvmsg

by David Howells

When a call is released, rxrpc takes the spinlock and removes it from ->recvmsg_q in an effort to prevent racing recvmsg() invocations from seeing the same call. Now, rxrpc_recvmsg() only takes the spinlock when actually removing a call from the queue; it doesn't, however, take it in the lead up to that when it checks to see if the queue is empty. It *does* hold the socket lock, which prevents a recvmsg/recvmsg race - but this doesn't prevent sendmsg from ending the call because sendmsg() drops the socket lock and relies on the call->user_mutex. Fix this by firstly removing the bit in rxrpc_release_call() that dequeues the released call and, instead, rely on recvmsg() to simply discard released calls (done in a preceding fix). Secondly, rxrpc_notify_socket() is abandoned if the call is already marked as released rather than trying to be clever by setting both pointers in call->recvmsg_link to NULL to trick list_empty(). This isn't perfect and can still race, resulting in a released call on the queue, but recvmsg() will now clean that up.

[PATCH v5] riscv: hwprobe: Fix stale vDSO data for late-initialized keys at boot

by Jingwei Wang

The hwprobe vDSO data for some keys, like MISALIGNED_VECTOR_PERF, is determined by an asynchronous kthread. This can create a race condition where the kthread finishes after the vDSO data has already been populated, causing userspace to read stale values. To fix this, a completion-based framework is introduced to robustly synchronize the async probes with the vDSO data population. The waiting function, init_hwprobe_vdso_data(), now blocks on wait_for_completion() until all probes signal they are done. Furthermore, to prevent this potential blocking from impacting boot performance, the initialization is deferred to late_initcall. This is safe as the data is only required by userspace (which starts much later) and moves the synchronization delay off the critical boot path. Reported-by: Tsukasa OI <research_trasio(a)irq.a4lg.com> Closes: https://lore.kernel.org/linux-riscv/760d637b-b13b-4518-b6bf-883d55d44e7f@ir… Fixes: e7c9d66e313b ("RISC-V: Report vector unaligned access speed hwprobe") Cc: Palmer Dabbelt <palmer(a)dabbelt.com> Cc: Alexandre Ghiti <alexghiti(a)rivosinc.com> Cc: Olof Johansson <olof(a)lixom.net> Cc: stable(a)vger.kernel.org Signed-off-by: Jingwei Wang <wangjingwei(a)iscas.ac.cn> --- Changes in v5: - Reworked the synchronization logic to a robust "sentinel-count" pattern based on feedback from Alexandre. - Fixed a "multiple definition" linker error for nommu builds by changing the header-file stub functions to `static inline`, as pointed out by Olof. - Updated the commit message to better explain the rationale for moving the vDSO initialization to `late_initcall`. Changes in v4: - Reworked the synchronization mechanism based on feedback from Palmer and Alexandre. - Instead of a post-hoc refresh, this version introduces a robust completion-based framework using an atomic counter to ensure async probes are finished before populating the vDSO. - Moved the vdso data initialization to a late_initcall to avoid impacting boot time. Changes in v3: - Retained existing blank line. Changes in v2: - Addressed feedback from Yixun's regarding #ifdef CONFIG_MMU usage. - Updated commit message to provide a high-level summary. - Added Fixes tag for commit e7c9d66e313b. v1: https://lore.kernel.org/linux-riscv/20250521052754.185231-1-wangjingwei@isc… arch/riscv/include/asm/hwprobe.h | 8 +++++++- arch/riscv/kernel/sys_hwprobe.c | 20 +++++++++++++++++++- arch/riscv/kernel/unaligned_access_speed.c | 9 +++++++-- 3 files changed, 33 insertions(+), 4 deletions(-) diff --git a/arch/riscv/include/asm/hwprobe.h b/arch/riscv/include/asm/hwprobe.h index 7fe0a379474ae2c6..3b2888126e659ea1 100644 --- a/arch/riscv/include/asm/hwprobe.h +++ b/arch/riscv/include/asm/hwprobe.h @@ -40,5 +40,11 @@ static inline bool riscv_hwprobe_pair_cmp(struct riscv_hwprobe *pair, return pair->value == other_pair->value; } - +#ifdef CONFIG_MMU +void riscv_hwprobe_register_async_probe(void); +void riscv_hwprobe_complete_async_probe(void); +#else +static inline void riscv_hwprobe_register_async_probe(void) {} +static inline void riscv_hwprobe_complete_async_probe(void) {} +#endif #endif diff --git a/arch/riscv/kernel/sys_hwprobe.c b/arch/riscv/kernel/sys_hwprobe.c index 0b170e18a2beba57..ee02aeb03e7bd3d8 100644 --- a/arch/riscv/kernel/sys_hwprobe.c +++ b/arch/riscv/kernel/sys_hwprobe.c @@ -5,6 +5,8 @@ * more details. */ #include <linux/syscalls.h> +#include <linux/completion.h> +#include <linux/atomic.h> #include <asm/cacheflush.h> #include <asm/cpufeature.h> #include <asm/hwprobe.h> @@ -467,6 +469,20 @@ static int do_riscv_hwprobe(struct riscv_hwprobe __user *pairs, #ifdef CONFIG_MMU +static DECLARE_COMPLETION(boot_probes_done); +static atomic_t pending_boot_probes = ATOMIC_INIT(1); + +void riscv_hwprobe_register_async_probe(void) +{ + atomic_inc(&pending_boot_probes); +} + +void riscv_hwprobe_complete_async_probe(void) +{ + if (atomic_dec_and_test(&pending_boot_probes)) + complete(&boot_probes_done); +} + static int __init init_hwprobe_vdso_data(void) { struct vdso_arch_data *avd = vdso_k_arch_data; @@ -474,6 +490,8 @@ static int __init init_hwprobe_vdso_data(void) struct riscv_hwprobe pair; int key; + if (unlikely(!atomic_dec_and_test(&pending_boot_probes))) + wait_for_completion(&boot_probes_done); /* * Initialize vDSO data with the answers for the "all CPUs" case, to * save a syscall in the common case. @@ -504,7 +522,7 @@ static int __init init_hwprobe_vdso_data(void) return 0; } -arch_initcall_sync(init_hwprobe_vdso_data); +late_initcall(init_hwprobe_vdso_data); #endif /* CONFIG_MMU */ diff --git a/arch/riscv/kernel/unaligned_access_speed.c b/arch/riscv/kernel/unaligned_access_speed.c index ae2068425fbcd207..4b8ad2673b0f7470 100644 --- a/arch/riscv/kernel/unaligned_access_speed.c +++ b/arch/riscv/kernel/unaligned_access_speed.c @@ -379,6 +379,7 @@ static void check_vector_unaligned_access(struct work_struct *work __always_unus static int __init vec_check_unaligned_access_speed_all_cpus(void *unused __always_unused) { schedule_on_each_cpu(check_vector_unaligned_access); + riscv_hwprobe_complete_async_probe(); return 0; } @@ -473,8 +474,12 @@ static int __init check_unaligned_access_all_cpus(void) per_cpu(vector_misaligned_access, cpu) = unaligned_vector_speed_param; } else if (!check_vector_unaligned_access_emulated_all_cpus() && IS_ENABLED(CONFIG_RISCV_PROBE_VECTOR_UNALIGNED_ACCESS)) { - kthread_run(vec_check_unaligned_access_speed_all_cpus, - NULL, "vec_check_unaligned_access_speed_all_cpus"); + riscv_hwprobe_register_async_probe(); + if (IS_ERR(kthread_run(vec_check_unaligned_access_speed_all_cpus, + NULL, "vec_check_unaligned_access_speed_all_cpus"))) { + pr_warn("Failed to create vec_unalign_check kthread\n"); + riscv_hwprobe_complete_async_probe(); + } } /* -- 2.50.0

decrement ep refcount while still holding the ep mutex MIME-Version: 1.0 6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Linus Torvalds <torvalds(a)linux-foundation.org> commit 8c2e52ebbe885c7eeaabd3b7ddcdc1246fc400d2 upstream. Jann Horn points out that epoll is decrementing the ep refcount and then doing a mutex_unlock(&ep->mtx); afterwards. That's very wrong, because it can lead to a use-after-free. That pattern is actually fine for the very last reference, because the code in question will delay the actual call to "ep_free(ep)" until after it has unlocked the mutex. But it's wrong for the much subtler "next to last" case when somebody *else* may also be dropping their reference and free the ep while we're still using the mutex. Note that this is true even if that other user is also using the same ep mutex: mutexes, unlike spinlocks, can not be used for object ownership, even if they guarantee mutual exclusion. A mutex "unlock" operation is not atomic, and as one user is still accessing the mutex as part of unlocking it, another user can come in and get the now released mutex and free the data structure while the first user is still cleaning up. See our mutex documentation in Documentation/locking/mutex-design.rst, in particular the section [1] about semantics: "mutex_unlock() may access the mutex structure even after it has internally released the lock already - so it's not safe for another context to acquire the mutex and assume that the mutex_unlock() context is not using the structure anymore" So if we drop our ep ref before the mutex unlock, but we weren't the last one, we may then unlock the mutex, another user comes in, drops _their_ reference and releases the 'ep' as it now has no users - all while the mutex_unlock() is still accessing it. Fix this by simply moving the ep refcount dropping to outside the mutex: the refcount itself is atomic, and doesn't need mutex protection (that's the whole _point_ of refcounts: unlike mutexes, they are inherently about object lifetimes).

[PATCH] kasan: use vmalloc_dump_obj() for vmalloc error reports

by Marco Elver

Since 6ee9b3d84775 ("kasan: remove kasan_find_vm_area() to prevent possible deadlock"), more detailed info about the vmalloc mapping and the origin was dropped due to potential deadlocks. While fixing the deadlock is necessary, that patch was too quick in killing an otherwise useful feature, and did no due-diligence in understanding if an alternative option is available. Restore printing more helpful vmalloc allocation info in KASAN reports with the help of vmalloc_dump_obj(). Example report: | BUG: KASAN: vmalloc-out-of-bounds in vmalloc_oob+0x4c9/0x610 | Read of size 1 at addr ffffc900002fd7f3 by task kunit_try_catch/493 | | CPU: [...] | Call Trace: | <TASK> | dump_stack_lvl+0xa8/0xf0 | print_report+0x17e/0x810 | kasan_report+0x155/0x190 | vmalloc_oob+0x4c9/0x610 | [...] | | The buggy address belongs to a 1-page vmalloc region starting at 0xffffc900002fd000 allocated at vmalloc_oob+0x36/0x610 | The buggy address belongs to the physical page: | page: refcount:1 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x126364 | flags: 0x200000000000000(node=0|zone=2) | raw: 0200000000000000 0000000000000000 dead000000000122 0000000000000000 | raw: 0000000000000000 0000000000000000 00000001ffffffff 0000000000000000 | page dumped because: kasan: bad access detected | | [..] Fixes: 6ee9b3d84775 ("kasan: remove kasan_find_vm_area() to prevent possible deadlock") Suggested-by: Uladzislau Rezki <urezki(a)gmail.com> Cc: Alexander Potapenko <glider(a)google.com> Cc: Andrey Konovalov <andreyknvl(a)gmail.com> Cc: Andrey Ryabinin <ryabinin.a.a(a)gmail.com> Cc: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> Cc: Yeoreum Yun <yeoreum.yun(a)arm.com> Cc: Yunseong Kim <ysk(a)kzalloc.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Marco Elver <elver(a)google.com> --- mm/kasan/report.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/mm/kasan/report.c b/mm/kasan/report.c index b0877035491f..62c01b4527eb 100644 --- a/mm/kasan/report.c +++ b/mm/kasan/report.c @@ -399,7 +399,9 @@ static void print_address_description(void *addr, u8 tag, } if (is_vmalloc_addr(addr)) { - pr_err("The buggy address %px belongs to a vmalloc virtual mapping\n", addr); + pr_err("The buggy address belongs to a"); + if (!vmalloc_dump_obj(addr)) + pr_cont(" vmalloc virtual mapping\n"); page = vmalloc_to_page(addr); } -- 2.50.0.727.gbf7dc18ff4-goog

[PATCH] usb: atm: cxacru: Zero initialize bp in cxacru_heavy_init()

by Nathan Chancellor

After a recent change in clang to expose uninitialized warnings from const variables [1], there is a warning in cxacru_heavy_init(): drivers/usb/atm/cxacru.c:1104:6: error: variable 'bp' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized] 1104 | if (instance->modem_type->boot_rom_patch) { | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/usb/atm/cxacru.c:1113:39: note: uninitialized use occurs here 1113 | cxacru_upload_firmware(instance, fw, bp); | ^~ drivers/usb/atm/cxacru.c:1104:2: note: remove the 'if' if its condition is always true 1104 | if (instance->modem_type->boot_rom_patch) { | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/usb/atm/cxacru.c:1095:32: note: initialize the variable 'bp' to silence this warning 1095 | const struct firmware *fw, *bp; | ^ | = NULL This warning occurs in clang's frontend before inlining occurs, so it cannot notice that bp is only used within cxacru_upload_firmware() under the same condition that initializes it in cxacru_heavy_init(). Just initialize bp to NULL to silence the warning without functionally changing the code, which is what happens with modern compilers when they support '-ftrivial-auto-var-init=zero' (CONFIG_INIT_STACK_ALL_ZERO=y).

[PATCH net v2 0/2] selftests: mptcp: connect: cover alt modes

by Matthieu Baerts (NGI0)

mptcp_connect.sh can be executed manually with "-m <MODE>" and "-C" to make sure everything works as expected when using "mmap" and "sendfile" modes instead of "poll", and with the MPTCP checksum support. These modes should be validated, but they are not when the selftests are executed via the kselftest helpers. It means that most CIs validating these selftests, like NIPA for the net development trees and LKFT for the stable ones, are not covering these modes. To fix that, new test programs have been added, simply calling mptcp_connect.sh with the right parameters. The first patch can be backported up to v5.6, and the second one up to v5.14. Signed-off-by: Matthieu Baerts (NGI0) <matttbe(a)kernel.org> --- Changes in v2: - force using a different prefix in the subtests to avoid having the same test names in all mptcp_connect*.sh selftests. - Link to v1: https://lore.kernel.org/r/20250714-net-mptcp-sft-connect-alt-v1-0-bf1c5abbe… --- Matthieu Baerts (NGI0) (2): selftests: mptcp: connect: also cover alt modes selftests: mptcp: connect: also cover checksum tools/testing/selftests/net/mptcp/Makefile | 3 ++- tools/testing/selftests/net/mptcp/mptcp_connect_checksum.sh | 5 +++++ tools/testing/selftests/net/mptcp/mptcp_connect_mmap.sh | 5 +++++ tools/testing/selftests/net/mptcp/mptcp_connect_sendfile.sh | 5 +++++ 4 files changed, 17 insertions(+), 1 deletion(-) --- base-commit: b640daa2822a39ff76e70200cb2b7b892b896dce change-id: 20250714-net-mptcp-sft-connect-alt-c1aaf073ef4e Best regards, -- Matthieu Baerts (NGI0) <matttbe(a)kernel.org>

[PATCH] vhost/net: Replace wait_queue with completion in ubufs reference

by Nikolay Kuratov

When operating on struct vhost_net_ubuf_ref, the following execution sequence is theoretically possible: CPU0 is finalizing DMA operation CPU1 is doing VHOST_NET_SET_BACKEND // &ubufs->refcount == 2 vhost_net_ubuf_put() vhost_net_ubuf_put_wait_and_free(oldubufs) vhost_net_ubuf_put_and_wait() vhost_net_ubuf_put() int r = atomic_sub_return(1, &ubufs->refcount); // r = 1 int r = atomic_sub_return(1, &ubufs->refcount); // r = 0 wait_event(ubufs->wait, !atomic_read(&ubufs->refcount)); // no wait occurs here because condition is already true kfree(ubufs); if (unlikely(!r)) wake_up(&ubufs->wait); // use-after-free This leads to use-after-free on ubufs access. This happens because CPU1 skips waiting for wake_up() when refcount is already zero. To prevent that use a completion instead of wait_queue as the ubufs notification mechanism. wait_for_completion() guarantees that there will be complete() call prior to its return. We also need to reinit completion because refcnt == 0 does not mean freeing in case of vhost_net_flush() - it then sets refcnt back to 1. AFAIK concurrent calls to vhost_net_ubuf_put_and_wait() with the same ubufs object aren't possible since those calls (through vhost_net_flush() or vhost_net_set_backend()) are protected by the device mutex. So reinit_completion() right after wait_for_completion() should be fine.

Re: [PATCH bpf-next v5 2/2] selftests/bpf: Add tests with stack ptr register in conditional jmp

I suppose it was meant to be squashed into the previous commit e2d2115e56c4 "bpf: Do not include stack ptr register in precision backtracking bookkeeping"? Since stable backports got only e2d2115e56c4, but not the 5ffb537e416e here with the extra change for kernel/bpf/verifier.c, I'd guess the backtracking logic in the stable kernel isn't correct at the moment, so I'll send 5ffb537e416e "selftests/bpf: Add tests with stack ptr register in conditional jmp" to stable as well. Let me know if that's not the right thing to do.

[PATCH v4 1/1] mm/rmap: fix potential out-of-bounds page table access during batched unmap

by Lance Yang

From: Lance Yang <lance.yang(a)linux.dev> As pointed out by David[1], the batched unmap logic in try_to_unmap_one() may read past the end of a PTE table when a large folio's PTE mappings are not fully contained within a single page table. While this scenario might be rare, an issue triggerable from userspace must be fixed regardless of its likelihood. This patch fixes the out-of-bounds access by refactoring the logic into a new helper, folio_unmap_pte_batch(). The new helper correctly calculates the safe batch size by capping the scan at both the VMA and PMD boundaries. To simplify the code, it also supports partial batching (i.e., any number of pages from 1 up to the calculated safe maximum), as there is no strong reason to special-case for fully mapped folios.

[PATCH v2] nvmem: layouts: u-boot-env: remove crc32 endianness conversion

by srini＠kernel.org

From: "Michael C. Pratt" <mcpratt(a)pm.me> On 11 Oct 2022, it was reported that the crc32 verification of the u-boot environment failed only on big-endian systems for the u-boot-env nvmem layout driver with the following error. Invalid calculated CRC32: 0x88cd6f09 (expected: 0x096fcd88) This problem has been present since the driver was introduced, and before it was made into a layout driver. The suggested fix at the time was to use further endianness conversion macros in order to have both the stored and calculated crc32 values to compare always represented in the system's endianness. This was not accepted due to sparse warnings and some disagreement on how to handle the situation. Later on in a newer revision of the patch, it was proposed to use cpu_to_le32() for both values to compare instead of le32_to_cpu() and store the values as __le32 type to remove compilation errors. The necessity of this is based on the assumption that the use of crc32() requires endianness conversion because the algorithm uses little-endian, however, this does not prove to be the case and the issue is unrelated. Upon inspecting the current kernel code, there already is an existing use of le32_to_cpu() in this driver, which suggests there already is special handling for big-endian systems, however, it is big-endian systems that have the problem. This, being the only functional difference between architectures in the driver combined with the fact that the suggested fix was to use the exact same endianness conversion for the values brings up the possibility that it was not necessary to begin with, as the same endianness conversion for two values expected to be the same is expected to be equivalent to no conversion at all. After inspecting the u-boot environment of devices of both endianness and trying to remove the existing endianness conversion, the problem is resolved in an equivalent way as the other suggested fixes. Ultimately, it seems that u-boot is agnostic to endianness at least for the purpose of environment variables. In other words, u-boot reads and writes the stored crc32 value with the same endianness that the crc32 value is calculated with in whichever endianness a certain architecture runs on. Therefore, the u-boot-env driver does not need to convert endianness. Remove the usage of endianness macros in the u-boot-env driver, and change the type of local variables to maintain the same return type. If there is a special situation in the case of endianness, it would be a corner case and should be handled by a unique "compatible". Even though it is not necessary to use endianness conversion macros here, it may be useful to use them in the future for consistent error printing.

[PATCH 6.12 1/2] arm64: defconfig: enable DRM_DISPLAY_CONNECTOR as a module

by Macpaul Lin

From: Dmitry Baryshkov <dmitry.baryshkov(a)linaro.org> [ Upstream commit 691b5b53dbcc30bb3572cbb255374990723af0d2 ] The display connector family of bridges is used on a plenty of ARM64 platforms (including, but not being limited to several Qualcomm Robotics and Dragonboard platforms). It doesn't make sense for the DRM drivers to select the driver, so select it via the defconfig.

[PATCH v2] media: pci: ivtv: Add missing check after DMA map

by Thomas Fourier

The DMA map functions can fail and should be tested for errors. If the mapping fails, free blanking_ptr and set it to 0. As 0 is a valid DMA address, use blanking_ptr to test if the DMA address is set.

[PATCH v2] KVM: SEV: Enforce minimum GHCB version requirement for SEV-SNP guests

by Nikunj A Dadhania

Require a minimum GHCB version of 2 when starting SEV-SNP guests through KVM_SEV_INIT2. When a VMM attempts to start an SEV-SNP guest with an incompatible GHCB version (less than 2), reject the request early rather than allowing the guest kernel to start with an incorrect protocol version and fail later with GHCB_SNP_UNSUPPORTED guest termination. Hypervisor logs the guest termination with GHCB_SNP_UNSUPPORTED error code: kvm_amd: SEV-ES guest requested termination: 0x0:0x2 SNP guest fails with the below error message: KVM: unknown exit reason 24 EAX=00000000 EBX=00000000 ECX=00000000 EDX=00a00f11 ESI=00000000 EDI=00000000 EBP=00000000 ESP=00000000 EIP=0000fff0 EFL=00000002 [-------] CPL=0 II=0 A20=1 SMM=0 HLT=0 ES =0000 00000000 0000ffff 00009300 CS =f000 ffff0000 0000ffff 00009b00 SS =0000 00000000 0000ffff 00009300 DS =0000 00000000 0000ffff 00009300 FS =0000 00000000 0000ffff 00009300 GS =0000 00000000 0000ffff 00009300 LDT=0000 00000000 0000ffff 00008200 TR =0000 00000000 0000ffff 00008b00 GDT= 00000000 0000ffff IDT= 00000000 0000ffff CR0=60000010 CR2=00000000 CR3=00000000 CR4=00000000 DR0=0000000000000000 DR1=0000000000000000 DR2=0000000000000000 DR3=0000000000000000 DR6=00000000ffff0ff0 DR7=0000000000000400 EFER=0000000000000000 Fixes: 4af663c2f64a ("KVM: SEV: Allow per-guest configuration of GHCB protocol version") Cc: Thomas Lendacky <thomas.lendacky(a)amd.com> Cc: Sean Christopherson <seanjc(a)google.com> Cc: Michael Roth <michael.roth(a)amd.com> Cc: stable(a)vger.kernel.org Signed-off-by: Nikunj A Dadhania <nikunj(a)amd.com> --- Changes since v1: * Add failure logs in the commit and drop @stable tag (Sean) --- arch/x86/kvm/svm/sev.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/arch/x86/kvm/svm/sev.c b/arch/x86/kvm/svm/sev.c index 95668e84ab86..fdc1309c68cb 100644 --- a/arch/x86/kvm/svm/sev.c +++ b/arch/x86/kvm/svm/sev.c @@ -406,6 +406,7 @@ static int __sev_guest_init(struct kvm *kvm, struct kvm_sev_cmd *argp, struct kvm_sev_info *sev = to_kvm_sev_info(kvm); struct sev_platform_init_args init_args = {0}; bool es_active = vm_type != KVM_X86_SEV_VM; + bool snp_active = vm_type == KVM_X86_SNP_VM; u64 valid_vmsa_features = es_active ? sev_supported_vmsa_features : 0; int ret; @@ -424,6 +425,9 @@ static int __sev_guest_init(struct kvm *kvm, struct kvm_sev_cmd *argp, if (unlikely(sev->active)) return -EINVAL; + if (snp_active && data->ghcb_version && data->ghcb_version < 2) + return -EINVAL; + sev->active = true; sev->es_active = es_active; sev->vmsa_features = data->vmsa_features; @@ -437,7 +441,7 @@ static int __sev_guest_init(struct kvm *kvm, struct kvm_sev_cmd *argp, if (sev->es_active && !sev->ghcb_version) sev->ghcb_version = GHCB_VERSION_DEFAULT; - if (vm_type == KVM_X86_SNP_VM) + if (snp_active) sev->vmsa_features |= SVM_SEV_FEAT_SNP_ACTIVE; ret = sev_asid_new(sev); @@ -455,7 +459,7 @@ static int __sev_guest_init(struct kvm *kvm, struct kvm_sev_cmd *argp, } /* This needs to happen after SEV/SNP firmware initialization. */ - if (vm_type == KVM_X86_SNP_VM) { + if (snp_active) { ret = snp_guest_req_init(kvm); if (ret) goto e_free; base-commit: 772d50d9b87bec08b56ecee0a880d6b2ee5c7da5 -- 2.43.0

[PATCH 6.6.y] arm64: Filter out SME hwcaps when FEAT_SME isn't implemented

by Mark Brown

[ Upstream commit a75ad2fc76a2ab70817c7eed3163b66ea84ca6ac ] We have a number of hwcaps for various SME subfeatures enumerated via ID_AA64SMFR0_EL1. Currently we advertise these without cross checking against the main SME feature, advertised in ID_AA64PFR1_EL1.SME which means that if the two are out of sync userspace can see a confusing situation where SME subfeatures are advertised without the base SME hwcap. This can be readily triggered by using the arm64.nosme override which only masks out ID_AA64PFR1_EL1.SME, and there have also been reports of VMMs which do the same thing. Fix this as we did previously for SVE in 064737920bdb ("arm64: Filter out SVE hwcaps when FEAT_SVE isn't implemented") by filtering out the SME subfeature hwcaps when FEAT_SME is not present.

[PATCH v2] iommu/amd: Fix geometry.aperture_end for V2 tables

by Jason Gunthorpe

The AMD IOMMU documentation seems pretty clear that the V2 table follows the normal CPU expectation of sign extension. This is shown in Figure 25: AMD64 Long Mode 4-Kbyte Page Address Translation Where bits Sign-Extend [63:57] == [56]. This is typical for x86 which would have three regions in the page table: lower, non-canonical, upper. The manual describes that the V1 table does not sign extend in section 2.2.4 Sharing AMD64 Processor and IOMMU Page Tables GPA-to-SPA Further, Vasant has checked this and indicates the HW has an addtional behavior that the manual does not yet describe. The AMDv2 table does not have the sign extended behavior when attached to PASID 0, which may explain why this has gone unnoticed. The iommu domain geometry does not directly support sign extended page tables. The driver should report only one of the lower/upper spaces. Solve this by removing the top VA bit from the geometry to use only the lower space. This will also make the iommu_domain work consistently on all PASID 0 and PASID != 1. Adjust dma_max_address() to remove the top VA bit. It now returns: 5 Level: Before 0x1ffffffffffffff After 0x0ffffffffffffff 4 Level: Before 0xffffffffffff After 0x7fffffffffff Fixes: 11c439a19466 ("iommu/amd/pgtbl_v2: Fix domain max address") Link: https://lore.kernel.org/all/8858d4d6-d360-4ef0-935c-bfd13ea54f42@amd.com/ Signed-off-by: Jason Gunthorpe <jgg(a)nvidia.com> --- drivers/iommu/amd/iommu.c | 17 +++++++++++++++-- 1 file changed, 15 insertions(+), 2 deletions(-) v2: - Revise the commit message and comment with the new information from Vasant. v1: https://patch.msgid.link/r/0-v1-6925ece6b623+296-amdv2_geo_jgg@nvidia.com diff --git a/drivers/iommu/amd/iommu.c b/drivers/iommu/amd/iommu.c index 3117d99cf83d0d..1baa9d3583f369 100644 --- a/drivers/iommu/amd/iommu.c +++ b/drivers/iommu/amd/iommu.c @@ -2526,8 +2526,21 @@ static inline u64 dma_max_address(enum protection_domain_mode pgtable) if (pgtable == PD_MODE_V1) return ~0ULL; - /* V2 with 4/5 level page table */ - return ((1ULL << PM_LEVEL_SHIFT(amd_iommu_gpt_level)) - 1); + /* + * V2 with 4/5 level page table.

[regression] Wireguard fragmentation fails with VXLAN since 8930424777e4 ("tunnels: Accept PACKET_HOST skb_tunnel_check_pmtu().") causing network timeouts

by Salvatore Bonaccorso

Hi, Charles Bordet reported the following issue (full context in https://bugs.debian.org/1108860) > Dear Maintainer, > > What led up to the situation? > We run a production environment using Debian 12 VMs, with a network > topology involving VXLAN tunnels encapsulated inside Wireguard > interfaces. This setup has worked reliably for over a year, with MTU set > to 1500 on all interfaces except the Wireguard interface (set to 1420). > Wireguard kernel fragmentation allowed this configuration to function > without issues, even though the effective path MTU is lower than 1500. > > What exactly did you do (or not do) that was effective (or ineffective)? > We performed a routine system upgrade, updating all packages include the > kernel. After the upgrade, we observed severe network issues (timeouts, > very slow HTTP/HTTPS, and apt update failures) on all VMs behind the > router. SSH and small-packet traffic continued to work. > > To diagnose, we: > > * Restored a backup (with the previous kernel): the problem disappeared. > * Repeated the upgrade, confirming the issue reappeared. > * Systematically tested each kernel version from 6.1.124-1 up to > 6.1.140-1. The problem first appears with kernel 6.1.135-1; all earlier > versions work as expected. > * Kernel version from the backports (6.12.32-1) did not resolve the > problem. > > What was the outcome of this action? > > * With kernel 6.1.135-1 or later, network timeouts occur for > large-packet protocols (HTTP, apt, etc.), while SSH and small-packet > protocols work. > * With kernel 6.1.133-1 or earlier, everything works as expected. > > What outcome did you expect instead? > We expected the network to function as before, with Wireguard handling > fragmentation transparently and no application-level timeouts, > regardless of the kernel version. While triaging the issue we found that the commit 8930424777e4 ("tunnels: Accept PACKET_HOST in skb_tunnel_check_pmtu()." introduces the issue and Charles confirmed that the issue was present as well in 6.12.35 and 6.15.4 (other version up could potentially still be affected, but we wanted to check it is not a 6.1.y specific regression). Reverthing the commit fixes Charles' issue. Does that ring a bell? Regards, Salvatore

[PATCH v2 1/1] iommu/sva: Invalidate KVA range on kernel TLB flush

by Lu Baolu

The vmalloc() and vfree() functions manage virtually contiguous, but not necessarily physically contiguous, kernel memory regions. When vfree() unmaps such a region, it tears down the associated kernel page table entries and frees the physical pages. In the IOMMU Shared Virtual Addressing (SVA) context, the IOMMU hardware shares and walks the CPU's page tables. Architectures like x86 share static kernel address mappings across all user page tables, allowing the IOMMU to access the kernel portion of these tables. Modern IOMMUs often cache page table entries to optimize walk performance, even for intermediate page table levels. If kernel page table mappings are changed (e.g., by vfree()), but the IOMMU's internal caches retain stale entries, Use-After-Free (UAF) vulnerability condition arises. If these freed page table pages are reallocated for a different purpose, potentially by an attacker, the IOMMU could misinterpret the new data as valid page table entries. This allows the IOMMU to walk into attacker-controlled memory, leading to arbitrary physical memory DMA access or privilege escalation. To mitigate this, introduce a new iommu interface to flush IOMMU caches and fence pending page table walks when kernel page mappings are updated. This interface should be invoked from architecture-specific code that manages combined user and kernel page tables.

[PATCH net 4/5] rxrpc: Fix transmission of an abort in response to an abort

by David Howells

Under some circumstances, such as when a server socket is closing, ABORT packets will be generated in response to incoming packets. Unfortunately, this also may include generating aborts in response to incoming aborts - which may cause a cycle. It appears this may be made possible by giving the client a multicast address. Fix this such that rxrpc_reject_packet() will refuse to generate aborts in response to aborts.

[PATCH net 2/5] rxrpc: Fix recv-recv race of completed call

by David Howells

If a call receives an event (such as incoming data), the call gets placed on the socket's queue and a thread in recvmsg can be awakened to go and process it. Once the thread has picked up the call off of the queue, further events will cause it to be requeued, and once the socket lock is dropped (recvmsg uses call->user_mutex to allow the socket to be used in parallel), a second thread can come in and its recvmsg can pop the call off the socket queue again. In such a case, the first thread will be receiving stuff from the call and the second thread will be blocked on call->user_mutex. The first thread can, at this point, process both the event that it picked call for and the event that the second thread picked the call for and may see the call terminate - in which case the call will be "released", decoupling the call from the user call ID assigned to it (RXRPC_USER_CALL_ID in the control message). The first thread will return okay, but then the second thread will wake up holding the user_mutex and, if it sees that the call has been released by the first thread, it will BUG thusly: kernel BUG at net/rxrpc/recvmsg.c:474! Fix this by just dequeuing the call and ignoring it if it is seen to be already released. We can't tell userspace about it anyway as the user call ID has become stale.

[PATCH net 1/5] rxrpc: Fix irq-disabled in local_bh_enable()

by David Howells

The rxrpc_assess_MTU_size() function calls down into the IP layer to find out the MTU size for a route. When accepting an incoming call, this is called from rxrpc_new_incoming_call() which holds interrupts disabled across the code that calls down to it. Unfortunately, the IP layer uses local_bh_enable() which, config dependent, throws a warning if IRQs are enabled: WARNING: CPU: 1 PID: 5544 at kernel/softirq.c:387 __local_bh_enable_ip+0x43/0xd0 ...

[PATCH] kernel/fork: Increase minimum number of allowed threads

by Hauke Mehrtens

From: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> A modern Linux system creates much more than 20 threads at bootup. When I booted up OpenWrt in qemu the system sometimes failed to boot up when it wanted to create the 419th thread. The VM had 128MB RAM and the calculation in set_max_threads() calculated that max_threads should be set to 419. When the system booted up it tried to notify the user space about every device it created because CONFIG_UEVENT_HELPER was set and used. I counted 1299 calles to call_usermodehelper_setup(), all of them try to create a new thread and call the userspace hotplug script in it. This fixes bootup of Linux on systems with low memory. I saw the problem with qemu 10.0.2 using these commands: qemu-system-aarch64 -machine virt -cpu cortex-a57 -nographic Cc: stable(a)vger.kernel.org Signed-off-by: Hauke Mehrtens <hauke(a)hauke-m.de> --- kernel/fork.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/fork.c b/kernel/fork.c index 7966c9a1c163..388299525f3c 100644 --- a/kernel/fork.c +++ b/kernel/fork.c @@ -115,7 +115,7 @@ /* * Minimum number of threads to boot the kernel */ -#define MIN_THREADS 20 +#define MIN_THREADS 600 /* * Maximum number of threads -- 2.50.1

[PATCH v5 2/3] drm/amdgpu: Reset the clear flag in buddy during resume

by Arunpravin Paneer Selvam

- Added a handler in DRM buddy manager to reset the cleared flag for the blocks in the freelist. - This is necessary because, upon resuming, the VRAM becomes cluttered with BIOS data, yet the VRAM backend manager believes that everything has been cleared. v2: - Add lock before accessing drm_buddy_clear_reset_blocks()(Matthew Auld) - Force merge the two dirty blocks.(Matthew Auld) - Add a new unit test case for this issue.(Matthew Auld) - Having this function being able to flip the state either way would be good. (Matthew Brost) v3(Matthew Auld): - Do merge step first to avoid the use of extra reset flag.

[PATCH] misc: rtsx: usb: Ensure mmc child device is active when card is present

by Ricky Wu

When a card is present in the reader, the driver currently defers autosuspend by returning -EAGAIN during the suspend callback to trigger USB remote wakeup signaling. However, this does not guarantee that the mmc child device has been resumed, which may cause issues if it remains suspended while the card is accessible. This patch ensures that all child devices, including the mmc host controller, are explicitly resumed before returning -EAGAIN. This fixes a corner case introduced by earlier remote wakeup handling, improving reliability of runtime PM when a card is inserted.
