[PATCH v1 OLK-6.6 0/4] kworker: Fix the problem of ipsan performance degradation on ARM architecture
by jiangdongxu 01 Mar '24

01 Mar '24

From: shaodenghui <shaodenghui(a)huawei.com> When the current downstream FS tests IPSAN, it is found that the performance on ARM is much worse than that on X86, and the test data of IPSAN fluctuates greatly. After analysis, the reason is that when iscsi issues IO, the task is sent to kworker for processing by iscsi_xmitworker. The workqueue created by iscsi can automatically identify the CPU of the soft interrupt currently processed by iscsi, and automatically schedule the workqueue to the corresponding NUMA node. shaodenghui (3): iscsi: add member for NUMA aware order workqueue workqueue: implement NUMA affinity for single thread workqueue iscsi: use dynamic single thread workqueue to improve performance drivers/scsi/iscsi_tcp.c | 9 +++++++++ drivers/scsi/libiscsi.c | 17 ++++++++++++----- include/linux/workqueue.h | 1 + include/scsi/libiscsi.h | 1 + kernel/workqueue.c | 15 ++++++++++----- 5 files changed, 33 insertions(+), 10 deletions(-) -- 2.33.0

[PATCH OLK-6.6] PCI: Avoid potential out-of-bounds read in pci_dev_for_each_resource()

From: Andy Shevchenko <andriy.shevchenko(a)linux.intel.com> stable inclusion from stable-v6.6.14 commit 5b3e25efe16e06779a9a7c7610217c1b921ec179 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I93L7H CVE: CVE-2023-52466 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 3171e46d677a668eed3086da78671f1e4f5b8405 ] Coverity complains that pointer in the pci_dev_for_each_resource() may be wrong, i.e., might be used for the out-of-bounds read. There is no actual issue right now because we have another check afterwards and the out-of-bounds read is not being performed. In any case it's better code with this fixed, hence the proposed change. As Jonas pointed out "It probably makes the code slightly less performant as res will now be checked for being not NULL (which will always be true), but I doubt it will be significant (or in any hot paths)."
