2021-09-24mm: fix uninitialized use in overcommit_policy_handlerChen Jun1-2/+2
We get an unexpected value of /proc/sys/vm/overcommit_memory after running the following program: int main() { int fd = open("/proc/sys/vm/overcommit_memory", O_RDWR); write(fd, "1", 1); write(fd, "2", 1); close(fd); } write(fd, "2", 1) will pass *ppos = 1 to proc_dointvec_minmax. proc_dointvec_minmax will return 0 without setting new_policy. t.data = &new_policy; ret = proc_dointvec_minmax(&t, write, buffer, lenp, ppos) -->do_proc_dointvec -->__do_proc_dointvec if (write) { if (proc_first_pos_non_zero_ignore(ppos, table)) goto out; sysctl_overcommit_memory = new_policy; so sysctl_overcommit_memory will be set to an uninitialized value.

2021-09-24kasan: always respect CONFIG_KASAN_STACKNathan Chancellor1-1/+2
Currently, the asan-stack parameter is only passed along if CFLAGS_KASAN_SHADOW is not empty, which requires KASAN_SHADOW_OFFSET to be defined in Kconfig so that the value can be checked. In RISC-V's case, KASAN_SHADOW_OFFSET is not defined in Kconfig, which means that asan-stack does not get disabled with clang even when CONFIG_KASAN_STACK is disabled, resulting in large stack warnings with allmodconfig: drivers/video/fbdev/omap2/omapfb/displays/panel-lgphilips-lb035q02.c:117:12: error: stack frame size (14400) exceeds limit (2048) in function 'lb035q02_connect' [-Werror,-Wframe-larger-than] static int lb035q02_connect(struct omap_dss_device *dssdev) ^ 1 error generated.

2021-09-24mm: fs: invalidate bh_lrus for only cold pathMinchan Kim3-7/+24
The kernel test robot reported the regression of fio.write_iops[1] with commit 8cc621d2f45d ("mm: fs: invalidate BH LRU during page migration"). Since lru_add_drain is called frequently, invalidate bh_lrus there could increase bh_lrus cache miss ratio, which needs more IO in the end. This patch moves the bh_lrus invalidation from the hot path( e.g., zap_page_range, pagevec_release) to cold path(i.e., lru_add_drain_all, lru_cache_disable). Zhengjun Xing confirmed "I test the patch, the regression reduced to -2.9%" [1] https://lore.kernel.org/lkml/20210520083144.GD14190@xsang-OptiPlex-9020/ [2] 8cc621d2f45d, mm: fs: invalidate BH LRU during page migration Link: https://lkml.kernel.org/r/20210907212347.1977686-1-minchan@kernel.org Signed-off-by: Minchan Kim <minchan@kernel.org> Reported-by: kernel test robot <oliver.sang@intel.com> Reviewed-by: Chris Goldsworthy <cgoldswo@codeaurora.org> Tested-by: "Xing, Zhengjun" <zhengjun.xing@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

ocfs2_data_convert_worker() is currently dropping any cached acl info for FILE before down-converting meta lock. It should also drop for DIRECTORY. Otherwise the second acl lookup returns the cached one (from VFS layer) which could be already stale.

2021-09-24mm/shmem.c: fix judgment error in shmem_is_huge()Liu Yuntao1-2/+2
In the case of SHMEM_HUGE_WITHIN_SIZE, the page index is not rounded up correctly. When the page index points to the first page in a huge page, round_up() cannot bring it to the end of the huge page, but to the end of the previous one. An example: HPAGE_PMD_NR on my machine is 512(2 MB huge page size). After allcoating a 3000 KB buffer, I access it at location 2050 KB. In shmem_is_huge(), the corresponding index happens to be 512. After rounded up by HPAGE_PMD_NR, it will still be 512 which is smaller than i_size, and shmem_is_huge() will return true. As a result, my buffer takes an additional huge page, and that shouldn't happen when shmem_enabled is set to within_size.

2021-09-24mm, hwpoison: add is_free_buddy_page() in HWPoisonHandlable()Naoya Horiguchi1-1/+1
Commit fcc00621d88b ("mm/hwpoison: retry with shake_page() for unhandlable pages") changed the return value of __get_hwpoison_page() to retry for transiently unhandlable cases. However, __get_hwpoison_page() currently fails to properly judge buddy pages as handlable, so hard/soft offline for buddy pages always fail as "unhandlable page". This is totally regrettable. So let's add is_free_buddy_page() in HWPoisonHandlable(), so that __get_hwpoison_page() returns different return values between buddy pages and unhandlable pages as intended.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Catalin Marinas: - It turns out that the optimised string routines merged in 5.14 are not safe with in-kernel MTE (KASAN_HW_TAGS) because of reading beyond the end of a string (strcmp, strncmp). Such reading may go across a 16 byte tag granule and cause a tag check fault. When KASAN_HW_TAGS is enabled, use the generic strcmp/strncmp C implementation. - An errata workaround for ThunderX relied on the CPU capabilities being enabled in a specific order. This disappeared with the automatic generation of the cpucaps.h file (sorted alphabetically). Fix it by checking the current CPU only rather than the system-wide capability. - Add system_supports_mte() checks on the kernel entry/exit path and thread switching to avoid unnecessary barriers and function calls on systems where MTE is not supported. - kselftests: skip arm64 tests if the required features are missing. * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: Restore forced disabling of KPTI on ThunderX kselftest/arm64: signal: Skip tests if required features are missing arm64: Mitigate MTE issues with str{n}cmp() arm64: add MTE supported check to thread switching and syscall entry/exit

2021-09-24block: hold ->invalidate_lock in blkdev_fallocateMing Lei1-11/+10
When running ->fallocate(), blkdev_fallocate() should hold mapping->invalidate_lock to prevent page cache from being accessed, otherwise stale data may be read in page cache. Without this patch, blktests block/009 fails sometimes. With this patch, block/009 can pass always. Also as Jan pointed out, no pages can be created in the discarded area while you are holding the invalidate_lock, so remove the 2nd truncate_bdev_range().

2021-09-24block: don't call rq_qos_ops->done_bio if the bio isn't trackedMing Lei1-1/+1
rq_qos framework is only applied on request based driver, so: 1) rq_qos_done_bio() needn't to be called for bio based driver 2) rq_qos_done_bio() needn't to be called for bio which isn't tracked, such as bios ended from error handling code. Especially in bio_endio(): 1) request queue is referred via bio->bi_bdev->bd_disk->queue, which may be gone since request queue refcount may not be held in above two cases 2) q->rq_qos may be freed in blk_cleanup_queue() when calling into __rq_qos_done_bio() Fix the potential kernel panic by not calling rq_qos_ops->done_bio if the bio isn't tracked. This way is safe because both ioc_rqos_done_bio() and blkcg_iolatency_done_bio() are nop if the bio isn't tracked.

For multishot mode, there may be cases like: iowq original context io_poll_add _arm_poll() mask = vfs_poll() is not 0 if mask (2) io_poll_complete() compl_unlock (interruption happens tw queued to original context) io_poll_task_func() compl_lock (3) done = io_poll_complete() is true compl_unlock put req ref (1) if (poll->flags & EPOLLONESHOT) put req ref EPOLLONESHOT flag in (1) may be from (2) or (3), so there are multiple combinations that can cause ref underfow. Let's address it by: - check the return value in (2) as done - change (1) to if (done) in this way, we only do ref put in (1) if 'oneshot flag' is from (2) - do poll.done check in io_poll_task_func(), so that we won't put ref for the second time.

Don't perform unaligned loads in __get_next() and __peek_nbyte_next() as these are forms of undefined behavior: "A pointer to an object or incomplete type may be converted to a pointer to a different object or incomplete type. If the resulting pointer is not correctly aligned for the pointed-to type, the behavior is undefined." (from http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf) These problems were identified using the undefined behavior sanitizer (ubsan) with the tools version of the code and perf test.
