[PATCH openEuler-22.09 0/4] add exec hugetlb support
by Zheng Zengkai 05 Aug '22

05 Aug '22

Some applications has large code and data segment, and this causes high TLB miss when page size is 4K. Mapping these apps into hugetlbfs will boost their performance. A userspace tool libhugetlbfs can do this but it seems to stopped development since 2020, and it does not support debugging. Tmpfs supports transparent hugepage, but it will be split into small pages during copy-on-write. Userspace hotpatch will do mprotect on code segment and trigger pmd split, and some users think performance degradation after hotpatch is unacceptable. This patch set implements hugetlb support in exec, and solved the debugging issue. --- v5: mark new Kconfigs default n and add sysctl knob v4: rebase to 5.10.0-107.0.0 v3: add MAP_FILE_HUGETLB v2: fix kabi Liu Zixian (4): hugetlb: support private file map elf: support hugetlb map enable elf huge map by default fs: add sysctl knob for exec_hugetlb arch/arm64/configs/openeuler_defconfig | 2 + arch/x86/configs/openeuler_defconfig | 2 + fs/Kconfig | 24 ++++++ fs/binfmt_elf.c | 115 +++++++++++++++++++++++++ fs/exec.c | 4 + fs/proc/task_mmu.c | 5 ++ include/linux/elf.h | 4 + include/linux/mm_types.h | 4 + include/uapi/asm-generic/mman-common.h | 1 + include/uapi/linux/elf.h | 1 + kernel/events/core.c | 7 ++ kernel/fork.c | 5 ++ kernel/sysctl.c | 11 +++ mm/hugetlb.c | 25 ++++++ mm/mmap.c | 20 +++++ mm/util.c | 40 +++++++++ 16 files changed, 270 insertions(+) -- 2.20.1

[PATCH openEuler-5.10 01/20] md: add io accounting for raid0 and raid5

From: Guoqing Jiang <jgq516(a)gmail.com> mainline inclusion from mainline-v5.14-rc1 commit 10764815ff4728d2c57da677cd5d3dd6f446cf5f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I587H6 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------- We introduce a new bioset (io_acct_set) for raid0 and raid5 since they don't own clone infrastructure to accounting io. And the bioset is added to mddev instead of to raid0 and raid5 layer, because with this way, we can put common functions to md.h and reuse them in raid0 and raid5. Also struct md_io_acct is added accordingly which includes io start_time, the origin bio and cloned bio. Then we can call bio_{start,end}_io_acct to get related io status.

[PATCH openEuler-1.0-LTS] rcu: Set a maximum limit for back-to-back callback invocation
by Yongqiang Liu 04 Aug '22

04 Aug '22

From: "Paul E. McKenney" <paulmck(a)linux.ibm.com> mainline inclusion from mainline-v5.3-rc1 commit d5a9a8c3bc8068f2e5dfba30150ac09b596b461a category: bugfix bugzilla: 187356, https://gitee.com/openeuler/kernel/issues/I5KOZ5 CVE: NA --------------------------- Currently, if a CPU has more than 10,000 callbacks pending, it will increase rdp->blimit to LONG_MAX. If you are lucky, LONG_MAX is only about two billion, but this is still a bit too many callbacks to invoke back-to-back while otherwise ignoring the world. This commit therefore sets a maximum limit of DEFAULT_MAX_RCU_BLIMIT, which is set to 10,000, for rdp->blimit. Reported-by: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> Signed-off-by: Paul E.

[PATCH openEuler-1.0-LTS] mm: Fix page counter mismatch in shmem_mfill_atomic_pte

04 Aug '22

From: Ma Wupeng <mawupeng1(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5JT6V CVE: NA -------------------------------- shmem_mfill_atomic_pte() wrongly called mem_cgroup_cancel_charge() in "success" path, it should mem_cgroup_uncharge() to dec memory counter instead. mem_cgroup_cancel_charge() should only be used if this transaction is unsuccessful and mem_cgroup_uncharge() is used to do this if this transaction succeed. This will lead to page->memcg not null and will uncharge one more in put_page(). The page counter will underflow to maximum value and trigger oom to kill all process include sshd and leave system unaccessible. page->memcg is set in the following path: mem_cgroup_commit_charge commit_charge page->mem_cgroup = memcg; extra uncharge will be done in the following path: put_page __put_page __put_single_page mem_cgroup_uncharge if (!page->mem_cgroup) <-- should return return uncharge_page uncharge_batch To fix this, call mem_cgroup_commit_charge() at the end of this transaction to make sure this transaction is really finished.
