From: Peter Zijlstra <peterz(a)infradead.org> mainline inclusion from mainline-v5.12-rc1 commit 2d24dd5798d0474d9bf705bfca8725e7d20f9d54 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I5OOWG CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------------------------------------------------- I've always been bothered by the endless (fragile) boilerplate for rbtree, and I recently wrote some rbtree helpers for objtool and figured I should lift them into the kernel and use them more widely. Provide: partial-order; less() based: - rb_add(): add a new entry to the rbtree - rb_add_cached(): like rb_add(), but for a rb_root_cached total-order; cmp() based: - rb_find(): find an entry in an rbtree - rb_find_add(): find an entry, and add if not found - rb_find_first(): find the first (leftmost) matching entry - rb_next_match(): continue from rb_find_first() - rb_for_each(): iterate a sub-tree using the previous two Inlining and constant propagation should see the compiler inline the whole thing, including the various compare functions.

[PATCH openEuler-5.10 01/10] mm: Force TLB flush for PFNMAP mappings before unlink_file_vma()
by Zheng Zengkai 29 Sep '22

29 Sep '22

From: Jann Horn <jannh(a)google.com> stable inclusion from stable-v5.10.142 commit 895428ee124ad70b9763259308354877b725c31d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5PE9S CVE: CVE-2022-39188 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- commit b67fbebd4cf980aecbcc750e1462128bffe8ae15 upstream. Some drivers rely on having all VMAs through which a PFN might be accessible listed in the rmap for correctness. However, on X86, it was possible for a VMA with stale TLB entries to not be listed in the rmap. This was fixed in mainline with commit b67fbebd4cf9 ("mmu_gather: Force tlb-flush VM_PFNMAP vmas"), but that commit relies on preceding refactoring in commit 18ba064e42df3 ("mmu_gather: Let there be one tlb_{start,end}_vma() implementation") and commit 1e9fdf21a4339 ("mmu_gather: Remove per arch tlb_{start,end}_vma()"). This patch provides equivalent protection without needing that refactoring, by forcing a TLB flush between removing PTEs in unmap_vmas() and the call to unlink_file_vma() in free_pgtables().

Therefore, the xfrm_trans_reinject executor is changed from tasklet to workqueue. Add add spin lock to protect the queue. This reduces the processing flow of the tcp_sendmsg function in this scenario.

[PATCH openEuler-1.0-LTS] Revert "cifs: fix double free race when mount fails in cifs_get_root()"
by Yongqiang Liu 29 Sep '22

29 Sep '22

From: Luo Meng <luomeng12(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5TMYD CVE: NA -------------------------------- This reverts commit 7959a47042a6c1ec5a97966cf3c04ee972b55348. Commit 2fe0e281f7ad (cifs: fix double free race when mount fails in cifs_get_root()) fixes a double free. However there is no such issue on 4.19 because it will return after cifs_cleanup_volume_info(). Since merge this patch, cifs_cleanup_volume_info() is skipped, leading to a memory leak.
