[PATCH OLK-5.10] drm/omap: fix misleading indentation in pixinc()

From: Arnd Bergmann <arnd(a)arndb.de> mainline inclusion from mainline-v5.13-rc1 commit 417fc6123b4a60c60b770e756cc3e001d764e480 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID96N8 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- An old patch added a 'return' statement after each BUG() in this driver, which was necessary at the time, but has become redundant after the BUG() definition was updated to handle this properly. gcc-11 now warns about one such instance, where the 'return' statement was incorrectly indented: drivers/gpu/drm/omapdrm/dss/dispc.c: In function ‘pixinc’: drivers/gpu/drm/omapdrm/dss/dispc.c:2093:9: error: this ‘else’ clause does not guard...

[PATCH OLK-6.6] bpf: Sync pending IRQ work before freeing ring buffer

In the syzbot reproducer, a BPF program attached to sched_switch triggers bpf_ringbuf_commit(), queuing an irq_work. If the ring buffer is freed before this work executes, the irq_work thread may accesses freed memory.

[PATCH OLK-6.6] nfsd: don't ignore the return code of svc_proc_register()
by Li Lingfeng 27 Nov '25

27 Nov '25

From: Jeff Layton <jlayton(a)kernel.org> mainline inclusion from mainline-v6.15-rc1 commit 930b64ca0c511521f0abdd1d57ce52b2a6e3476b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC1QT8 CVE: CVE-2025-22026 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Currently, nfsd_proc_stat_init() ignores the return value of svc_proc_register(). If the procfile creation fails, then the kernel will WARN when it tries to remove the entry later. Fix nfsd_proc_stat_init() to return the same type of pointer as svc_proc_register(), and fix up nfsd_net_init() to check that and fail the nfsd_net construction if it occurs. svc_proc_register() can fail if the dentry can't be allocated, or if an identical dentry already exists. The second case is pretty unlikely in the nfsd_net construction codepath, so if this happens, return -ENOMEM.

[PATCH OLK-6.6] xcall2.0: Fix mem leak in proc_xcall_command

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/release-management/issues/ID5CMS -------------------------------- There is a test which is registering and unregistering xcall by /proc/xcall/comm in multithread.

This is why the memleak happened. And it has another bug which is xcall has been unregistered, but we can still find it in /proc/ xcall/comm. ------------------------------------------------------- A thread B thread ------------------------------------------------------- xcall_attach insert_xcall_locked xcall_detach delete_xcall_comm_locked insert_xcall_comm_locked ------------------------------------------------------- To solve this problem, merge struct xcall_comm into struct xcall. Make sure this two struct is protected by the same lock. So they will be consistent.

[PATCH v8 00/12] arm64: entry: Convert to Generic Entry
by Jinjie Ruan 26 Nov '25

26 Nov '25

Currently, x86, Riscv, Loongarch use the Generic Entry which makes maintainers' work easier and codes more elegant. arm64 has already successfully switched to the Generic IRQ Entry in commit b3cf07851b6c ("arm64: entry: Switch to generic IRQ entry"), it is time to completely convert arm64 to Generic Entry. The goal is to bring arm64 in line with other architectures that already use the generic entry infrastructure, reducing duplicated code and making it easier to share future changes in entry/exit paths, such as "Syscall User Dispatch". This patch set is rebased on v6.18-rc6. The performance benchmarks from perf bench basic syscall on real hardware are below: | Metric | W/O Generic Framework | With Generic Framework | Change | | ---------- | --------------------- | ---------------------- | ------ | | Total time | 2.813 [sec] | 2.930 [sec] | ↑4% | | usecs/op | 0.281349 | 0.293006 | ↑4% | | ops/sec | 3,554,299 | 3,412,894 | ↓4% | Compared to earlier with arch specific handling, the performance decreased by approximately 4%. It was tested ok with following test cases on QEMU virt platform: - Perf tests. - Different `dynamic preempt` mode switch. - Pseudo NMI tests. - Stress-ng CPU stress test. - Hackbench stress test. - MTE test case in Documentation/arch/arm64/memory-tagging-extension.rst and all test cases in tools/testing/selftests/arm64/mte/*. - "sud" selftest testcase. - get_syscall_info, peeksiginfo in tools/testing/selftests/ptrace. - Strace tests. The test QEMU configuration is as follows: qemu-system-aarch64 \ -M virt,gic-version=3,virtualization=on,mte=on \ cpu max,pauth-impdef=on \ kernel Image \ smp 8,sockets=1,cores=4,threads=2 \ m 512m \ nographic \ no-reboot \ device virtio-rng-pci \ append "root=/dev/vda rw console=ttyAMA0 kgdboc=ttyAMA0,115200 \ earlycon preempt=voluntary irqchip.gicv3_pseudo_nmi=1" \ drive if=none,file=images/rootfs.ext4,format=raw,id=hd0 \ device virtio-blk-device,drive=hd0 \ Changes in v8: - Rename "report_syscall_enter()" to "report_syscall_entry()". - Add ptrace_save_reg() to avoid duplication. - Remove unused _TIF_WORK_MASK in a standalone patch. - Align syscall_trace_enter() return value with the generic version. - Use "scno" instead of regs->syscallno in el0_svc_common(). - Move rseq_syscall() ahead in a standalone patch to clarify it clearly. - Rename "syscall_trace_exit()" to "syscall_exit_work()". - Keep the goto in el0_svc_common(). - No argument was passed to __secure_computing() and check -1 not -1L. - Remove "Add has_syscall_work() helper" patch. - Move "Add syscall_exit_to_user_mode_prepare() helper" patch later. - Add miss header for asm/entry-common.h. - Update the implementation of arch_syscall_is_vdso_sigreturn(). - Add "ARCH_SYSCALL_WORK_EXIT" to be defined as "SECCOMP | SYSCALL_EMU" to keep the behaviour unchanged. - Add more strace testcases test. - Add Reviewed-by. - Update the commit message. - Link to v7: https://lore.kernel.org/all/20251117133048.53182-1-ruanjinjie@huawei.com/ Chanegs in v7: - Support "Syscall User Dispatch" by implementing arch_syscall_is_vdso_sigreturn() as kemal suggested. - Add aarch64 support for "sud" selftest testcase, which tested ok with the patch series. - Fix the kernel test robot warning for arch_ptrace_report_syscall_entry() and arch_ptrace_report_syscall_exit() in asm/entry-common.h. - Add perf syscall performance test. - Link to v6: https://lore.kernel.org/all/20250916082611.2972008-1-ruanjinjie@huawei.com/ Changes in v6: - Rebased on v6.17-rc5-next as arm64 generic irq entry has merged. - Update the commit message. - Link to v5: https://lore.kernel.org/all/20241206101744.4161990-1-ruanjinjie@huawei.com/ Changes in v5: - Not change arm32 and keep inerrupts_enabled() macro for gicv3 driver. - Move irqentry_state definition into arch/arm64/kernel/entry-common.c. - Avoid removing the __enter_from_*() and __exit_to_*() wrappers. - Update "irqentry_state_t ret/irq_state" to "state" to keep it consistently. - Use generic irq entry header for PREEMPT_DYNAMIC after split the generic entry. - Also refactor the ARM64 syscall code. - Introduce arch_ptrace_report_syscall_entry/exit(), instead of arch_pre/post_report_syscall_entry/exit() to simplify code. - Make the syscall patches clear separation. - Update the commit message. - Link to v4: https://lore.kernel.org/all/20241025100700.3714552-1-ruanjinjie@huawei.com/ Changes in v4: - Rework/cleanup split into a few patches as Mark suggested. - Replace interrupts_enabled() macro with regs_irqs_disabled(), instead of left it here. - Remove rcu and lockdep state in pt_regs by using temporary irqentry_state_t as Mark suggested. - Remove some unnecessary intermediate functions to make it clear. - Rework preempt irq and PREEMPT_DYNAMIC code to make the switch more clear. - arch_prepare_*_entry/exit() -> arch_pre_*_entry/exit(). - Expand the arch functions comment. - Make arch functions closer to its caller. - Declare saved_reg in for block. - Remove arch_exit_to_kernel_mode_prepare(), arch_enter_from_kernel_mode(). - Adjust "Add few arch functions to use generic entry" patch to be the penultimate. - Update the commit message. - Add suggested-by. - Link to v3: https://lore.kernel.org/all/20240629085601.470241-1-ruanjinjie@huawei.com/ Changes in v3: - Test the MTE test cases. - Handle forget_syscall() in arch_post_report_syscall_entry() - Make the arch funcs not use __weak as Thomas suggested, so move the arch funcs to entry-common.h, and make arch_forget_syscall() folded in arch_post_report_syscall_entry() as suggested. - Move report_single_step() to thread_info.h for arm64 - Change __always_inline() to inline, add inline for the other arch funcs. - Remove unused signal.h for entry-common.h. - Add Suggested-by. - Update the commit message. Changes in v2: - Add tested-by. - Fix a bug that not call arch_post_report_syscall_entry() in syscall_trace_enter() if ptrace_report_syscall_entry() return not zero. - Refactor report_syscall(). - Add comment for arch_prepare_report_syscall_exit(). - Adjust entry-common.h header file inclusion to alphabetical order. - Update the commit message.

From: Harshit Agarwal <harshit(a)nutanix.com> mainline inclusion from mainline-v6.16-rc1 commit 690e47d1403e90b7f2366f03b52ed3304194c793 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICK4N0 CVE: CVE-2025-38234 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Overview ======== When a CPU chooses to call push_rt_task and picks a task to push to another CPU's runqueue then it will call find_lock_lowest_rq method which would take a double lock on both CPUs' runqueues. If one of the locks aren't readily available, it may lead to dropping the current runqueue lock and reacquiring both the locks at once. During this window it is possible that the task is already migrated and is running on some other CPU. These cases are already handled. However, if the task is migrated and has already been executed and another CPU is now trying to wake it up (ttwu) such that it is queued again on the runqeue (on_rq is 1) and also if the task was run by the same CPU, then the current checks will pass even though the task was migrated out and is no longer in the pushable tasks list. Crashes ======= This bug resulted in quite a few flavors of crashes triggering kernel panics with various crash signatures such as assert failures, page faults, null pointer dereferences, and queue corruption errors all coming from scheduler itself. Some of the crashes: -> kernel BUG at kernel/sched/rt.c:1616!

Details ======= Let's look at the following scenario to understand this race. 1) CPU A enters push_rt_task a) CPU A has chosen next_task = task p. b) CPU A calls find_lock_lowest_rq(Task p, CPU Z’s rq). c) CPU A identifies CPU X as a destination CPU (X < Z). d) CPU A enters double_lock_balance(CPU Z’s rq, CPU X’s rq). e) Since X is lower than Z, CPU A unlocks CPU Z’s rq. Someone else has locked CPU X’s rq, and thus, CPU A must wait. 2) At CPU Z a) Previous task has completed execution and thus, CPU Z enters schedule, locks its own rq after CPU A releases it. b) CPU Z dequeues previous task and begins executing task p. c) CPU Z unlocks its rq. d) Task p yields the CPU (ex. by doing IO or waiting to acquire a lock) which triggers the schedule function on CPU Z. e) CPU Z enters schedule again, locks its own rq, and dequeues task p. f) As part of dequeue, it sets p.on_rq = 0 and unlocks its rq. 3) At CPU B a) CPU B enters try_to_wake_up with input task p. b) Since CPU Z dequeued task p, p.on_rq = 0, and CPU B updates B.state = WAKING. c) CPU B via select_task_rq determines CPU Y as the target CPU. 4) The race a) CPU A acquires CPU X’s lock and relocks CPU Z. b) CPU A reads task p.cpu = Z and incorrectly concludes task p is still on CPU Z. c) CPU A failed to notice task p had been dequeued from CPU Z while CPU A was waiting for locks in double_lock_balance. If CPU A knew that task p had been dequeued, it would return NULL forcing push_rt_task to give up the task p's migration. d) CPU B updates task p.cpu = Y and calls ttwu_queue. e) CPU B locks Ys rq. CPU B enqueues task p onto Y and sets task p.on_rq = 1. f) CPU B unlocks CPU Y, triggering memory synchronization. g) CPU A reads task p.on_rq = 1, cementing its assumption that task p has not migrated. h) CPU A decides to migrate p to CPU X. This leads to A dequeuing p from Y's queue and various crashes down the line. Solution ======== The solution here is fairly simple. After obtaining the lock (at 4a), the check is enhanced to make sure that the task is still at the head of the pushable tasks list. If not, then it is anyway not suitable for being pushed out. Testing ======= The fix is tested on a cluster of 3 nodes, where the panics due to this are hit every couple of days. A fix similar to this was deployed on such cluster and was stable for more than 30 days.

[PATCH OLK-6.6] blk-ioinf: accumulate total latency properly across sampling periods
by Baokun Li 26 Nov '25

26 Nov '25

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/ID0C1D -------------------------------- QoS evaluation based on delta_stat should only be performed when the number of samples exceeds IOINF_MIN_SAMPLES. Otherwise, abnormal cases in small sample sets may cause overly aggressive adjustments. Therefore, when updating delta_stat, it is only reset if the number of I/Os exceeds IOINF_MIN_SAMPLES; otherwise, sampling results are accumulated across multiple periods until the total sample count reaches at least IOINF_MIN_SAMPLES. However, when accumulating across multiple periods, the average latency was treated as total latency, leading to underestimated values. Fix this by introducing a variable to track total latency. In addition, since the update logic for read and write is identical, a helper function ioinf_update_delta_io_stat() is added to avoid code duplication.
