[PATCH] crypto: hisilicon/qm - check function qp num before alg register

From: Weili Qian <qianweili(a)huawei.com> mainline inclusion from mainline-v6.7-rc1 commit b42ab1c61a77832040ad42ebf9adf237360e49f7 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I8IVG6 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ---------------------------------------------------------------------- When the Kunpeng accelerator executes tasks such as encryption and decryption have minimum requirements on the number of device queues. 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-6.6 v2] net: sched: sch_qfq: Use non-work-conserving warning handler
