Fix it by adding a `kfree()` in the error handling path in `try_smi_init()`.

[PATCH OLK-6.6 v2] anolis: bond: broadcast ARP or ND messages to all slaves
by Zhengchao Shao 27 Nov '23

27 Nov '23

[PATCH openEuler-1.0-LTS] umh: fix memory leak on execve failure
by Wenyu Huang 27 Nov '23

27 Nov '23

From: Vincent Minet <v.minet(a)criteo.com> mainline inclusion from mainline commit db803036ada7d61d096783726f9771b3fc540370 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8J9MA CVE: NA ------------------------------------------------- If a UMH process created by fork_usermode_blob() fails to execute, a pair of struct file allocated by umh_pipe_setup() will leak. Under normal conditions, the caller (like bpfilter) needs to manage the lifetime of the UMH and its two pipes. But when fork_usermode_blob() fails, the caller doesn't really have a way to know what needs to be done. It seems better to do the cleanup ourselves in this case.

[PATCH OLK-5.10 0/2] fix CFS bandwidth vs. hrtimer self deadlock
by Yu Liao 25 Nov '23

25 Nov '23

Fix the following issue: CPU1 CPU2 CPU3 T1 sets cfs_quota starts hrtimer cfs_bandwidth 'period_timer' T1 is migrated to CPU3 T2(worker thread) initiates offlining of CPU1 Hotplug operation starts ... 'period_timer' expires and is re-enqueued on CPU1 ... take_cpu_down() CPU1 shuts down and does not handle timers anymore. They have to be migrated in the post dead hotplug steps by the control task. T2(worker thread) runs the post dead offline operation T1 holds lockA T1 is scheduled out //throttled by CFS bandwidth control T1 waits for 'period_timer' to expire T2(worker thread) waits for lockA T1 waits there forever if it is scheduled out before it can execute the hrtimer offline callback hrtimers_dead_cpu(). Thus T2 waits for lockA forever.

[PATCH OLK-6.6] fs/dcache.c: avoid panic while lockref of dentry overflow
by Zizhi Wo 25 Nov '23

25 Nov '23

From: yangerkun <yangerkun(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8JDP6?from=project-issue --------------------------- We use lockref for dentry reference without notice that so many negative dentry under one dir can lead to overflow of lockref. This can lead to system crash if we do this under root dir. Since there is not a perfect solution, we just limit max number of dentry count up to INT_MAX / 2. Also, it will cost a lot of time from INT_MAX / 2 to INT_MAX, so we no need to do this under protection of dentry lock. Also, we limit the FILES_MAX to INT_MAX / 2, since a lot open for same file can lead to overflow too.

[PATCH openEuler-1.0-LTS] x86/mce/amd: Publish the bank pointer only after setup has succeeded
by liwei 25 Nov '23

From: Borislav Petkov <bp(a)suse.de> mainline inclusion from mainline-v5.6-rc3 commit 6e5cf31fbe651bed7ba1df768f2e123531132417 category: bugfix bugzilla: 189381 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- threshold_create_bank() creates a bank descriptor per MCA error thresholding counter which can be controlled over sysfs. It publishes the pointer to that bank in a per-CPU variable and then goes on to create additional thresholding blocks if the bank has such. However, that creation of additional blocks in allocate_threshold_blocks() can fail, leading to a use-after-free through the per-CPU pointer. Therefore, publish that pointer only after all blocks have been setup successfully.

[PATCH openEuler-1.0-LTS] umh: fix memory leak on execve failure

If the number of queues does not meet the requirement, the process initialization will fail. Therefore, the driver checks the number of queues on the device before registering the algorithm. If the number does not meet the requirements, the driver does not register the algorithm to crypto subsystem, the device is still added to the qm_list.

[PATCH openEuler-1.0-LTS] umh: fix memory leak on execve failure
by Wenyu Huang 24 Nov '23

24 Nov '23

From: Vincent Minet <v.minet(a)criteo.com> mainline inclusion from mainline-5.10 commit db803036ada7 ("umh: fix memory leak on execve failure") category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8J9MA CVE: NA ------------------------------------------------- If a UMH process created by fork_usermode_blob() fails to execute, a pair of struct file allocated by umh_pipe_setup() will leak. Under normal conditions, the caller (like bpfilter) needs to manage the lifetime of the UMH and its two pipes. But when fork_usermode_blob() fails, the caller doesn't really have a way to know what needs to be done. It seems better to do the cleanup ourselves in this case.

[PATCH OLK-5.10] time/sched_clock: Remove clock_read_data's read mostly members
by Zeng Heng 24 Nov '23

24 Nov '23

hulk inclusion category: performance bugzilla: https://gitee.com/openeuler/kernel/issues/I8J8UH -------------------------------- In the clock_read_data structure, the epoch_ns and epoch_cyc members are often updated by the update_sched_clock(). In fact, the sched_clock_mask, read_sched_clock, mult, and shift will no longer change after they are initialized and registered in sched_clock_register().

[PATCH OLK-5.10] time/sched_clock: Remove clock_read_data's read mostly members
by Zeng Heng 24 Nov '23

24 Nov '23

In the clock_read_data structure, the epoch_ns and epoch_cyc members are often updated by the update_sched_clock(). In fact, the sched_clock_mask, read_sched_clock, mult, and shift will no longer change after they are initialized and registered in sched_clock_register(). Because all of them are in the same cache line, especially in multi-core scenarios, this will cause frequent cache miss. Here we move these almostly read-only members into the struct clock_data to avoid false share with epoch_* members, and separate them into different cache line with padding.

[PATCH openEuler-1.0-LTS] x86/MCE/AMD: Clear DFR errors found in THR handler
by liwei 24 Nov '23

24 Nov '23

From: Yazen Ghannam <yazen.ghannam(a)amd.com> mainline inclusion from mainline-v6.2-rc1 commit bc1b705b0eee4c645ad8b3bbff3c8a66e9688362 category: bugfix bugzilla: 189379 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- AMD's MCA Thresholding feature counts errors of all severity levels, not just correctable errors. If a deferred error causes the threshold limit to be reached (it was the error that caused the overflow), then both a deferred error interrupt and a thresholding interrupt will be triggered. The order of the interrupts is not guaranteed. If the threshold interrupt handler is executed first, then it will clear MCA_STATUS for the error. It will not check or clear MCA_DESTAT which also holds a copy of the deferred error. When the deferred error interrupt handler runs it will not find an error in MCA_STATUS, but it will find the error in MCA_DESTAT. This will cause two errors to be logged. Check for deferred errors when handling a threshold interrupt. If a bank contains a deferred error, then clear the bank's MCA_DESTAT register. Define a new helper function to do the deferred error check and clearing of MCA_DESTAT.

[PATCH OLK-5.10] ksmbd: delete asynchronous work from list
by Zizhi Wo 23 Nov '23

23 Nov '23

From: Namjae Jeon <linkinjeon(a)kernel.org> mainline inclusion from mainline-v6.3-rc6 commit 3a9b557f44ea8f216aab515a7db20e23f0eb51b9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6KEWO?from=project-issue CVE: CVE-2023-1193 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When smb2_lock request is canceled by smb2_cancel or smb2_close(), ksmbd is missing deleting async_request_entry async_requests list.
