[PATCH OLK-5.10] net/oenetcls: introduce oenetcls for network optimization
by Wang Liang 30 May '25

30 May '25

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/ICBFCS CVE: NA -------------------------------- This introduces a kind of network optimization method named oenetcls. It can configure the ntuple rule, and bind interrupt to the netdev queue automatically.

From: Frederic Weisbecker <frederic(a)kernel.org> mainline inclusion from mainline-v6.15-rc2 commit 56799bc035658738f362acec3e7647bb84e68933 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC5BL4 CVE: CVE-2025-37747 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Perf can hang while freeing a sigtrap event if a related deferred signal hadn't managed to be sent before the file got closed: perf_event_overflow() task_work_add(perf_pending_task) fput() task_work_add(____fput()) task_work_run() ____fput() perf_release() perf_event_release_kernel() _free_event() perf_pending_task_sync() task_work_cancel() -> FAILED rcuwait_wait_event() Once task_work_run() is running, the list of pending callbacks is removed from the task_struct and from this point on task_work_cancel() can't remove any pending and not yet started work items, hence the task_work_cancel() failure and the hang on rcuwait_wait_event(). Task work could be changed to remove one work at a time, so a work running on the current task can always cancel a pending one, however the wait / wake design is still subject to inverted dependencies when remote targets are involved, as pictured by Oleg: T1 T2 fd = perf_event_open(pid => T2->pid); fd = perf_event_open(pid => T1->pid); close(fd) close(fd) <IRQ> <IRQ> perf_event_overflow() perf_event_overflow() task_work_add(perf_pending_task) task_work_add(perf_pending_task) </IRQ> </IRQ> fput() fput() task_work_add(____fput()) task_work_add(____fput()) task_work_run() task_work_run() ____fput() ____fput() perf_release() perf_release() perf_event_release_kernel() perf_event_release_kernel() _free_event() _free_event() perf_pending_task_sync() perf_pending_task_sync() rcuwait_wait_event() rcuwait_wait_event() Therefore the only option left is to acquire the event reference count upon queueing the perf task work and release it from the task work, just like it was done before 3a5465418f5f ("perf: Fix event leak upon exec and file release") but without the leaks it fixed. Some adjustments are necessary to make it work: * A child event might dereference its parent upon freeing. Care must be taken to release the parent last. * Some places assuming the event doesn't have any reference held and therefore can be freed right away must instead put the reference and let the reference counting to its job.

[PATCH openEuler-1.0-LTS] scsi: target: Fix WRITE_SAME No Data Buffer crash
by Zheng Qixing 30 May '25

30 May '25

From: Mike Christie <michael.christie(a)oracle.com> mainline inclusion from mainline-v5.19-rc7 commit ccd3f449052449a917a3e577d8ba0368f43b8f29 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC5J9X CVE: CVE-2022-21546 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------ In newer version of the SBC specs, we have a NDOB bit that indicates there is no data buffer that gets written out. If this bit is set using commands like "sg_write_same --ndob" we will crash in target_core_iblock/file's execute_write_same handlers when we go to access the se_cmd->t_data_sg because its NULL. This patch adds a check for the NDOB bit in the common WRITE SAME code because we don't support it. And, it adds a check for zero SG elements in each handler in case the initiator tries to send a normal WRITE SAME with no data buffer.
