[PATCH v2 openEuler-23.09 0/1] kernel: add OPENEULER_VERSION_CODE to version.h
by Xie XiuQi 12 Sep '23

12 Sep '23

Add OPENEULER_VERSION_CODE to version.h, so modules or applications can identify the specific kernel version. In most cases, the out-of-tree module needs to identify the release version of the openEuler for interface adaptation. The existing OPENEULER_VERSION() and OPENEULER_VERSION_CODE() cannot distinguish between LTS versions and innovative versions. Therefore, a new macro OPENEULER_LTS is introduced. The version information is generated in "linux/version.h", as bellow: include/generated/uapi/linux/version.h ``` #define OPENEULER_LTS 0 // 1: LTS; 0: none LTS #define OPENEULER_MAJOR 9999 // OS Major version, 9999: none released #define OPENEULER_MINOR 0 // SP release version #define OPENEULER_VERSION(a,b) (((a) << 8) + (b)) #define OPENEULER_VERSION_CODE 2559744 ``` Use Makefile.oever to avoid future merge conflicts. https://gitee.com/openeuler/kernel/pulls/1442 https://gitee.com/openeuler/kernel/issues/I7LEXY https://gitee.com/openeuler/kernel/issues/I575IT https://gitee.com/openeuler/kernel/issues/I7761D Xie XiuQi (1): kernel: add OPENEULER_VERSION_CODE to version.h --- v2: fix commit message format error for pr 1442 Makefile | 11 ++++++++++- Makefile.oever | 4 ++++ 2 files changed, 14 insertions(+), 1 deletion(-) create mode 100644 Makefile.oever -- 2.20.1

[PATCH openEuler-1.0-LTS] io_uring: ensure IOPOLL locks around deferred work

11 Sep '23

From: Jens Axboe <axboe(a)kernel.dk> stable inclusion from stable-v5.10.188 commit 810e401b34c4c4c244d8b93b9947ea5b3d4d49f8 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7KXLN CVE: CVE-2023-21400 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- No direct upstream commit exists for this issue. It was fixed in 5.18 as part of a larger rework of the completion side. io_commit_cqring() writes the CQ ring tail to make it visible, but it also kicks off any deferred work we have. A ring setup with IOPOLL does not need any locking around the CQ ring updates, as we're always under the ctx uring_lock. But if we have deferred work that needs processing, then io_queue_deferred() assumes that the completion_lock is held, as it is for !IOPOLL. Add a lockdep assertion to check and document this fact, and have io_iopoll_complete() check if we have deferred work and run that separately with the appropriate lock grabbed.
