hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8UTJ5 CVE: NA -------------------------------- While performing the io fault injection test, I caught the following data corruption report: XFS (dm-6): Internal error ltbno + ltlen > bno at line 1976 of file fs/xfs/libxfs/xfs_alloc.c.

Unmount and run xfs_repair After analyzing the disk image, I found that the cause of the problem was that the transactions were not replayed. The problem arises in that the iclog buffer IO completion updates the l_last_sync_lsn with it's own LSN. Transactions can be large enough to span many iclogs, only commit iclog goes to update l_last_sync_lsn. Since the last_sync_lsn update and the insertion of the item into the ail list releases the l_icloglock, if the ail is is empty in the meantime, the new iclog gets the last_sync_lsn as tail lsn. If the new iclog is written to disk and a shutdown occurs, the current iclog will not be able to replay in the next mount. xlog_state_done_syncing xlog_state_do_callback spin_lock(&log->l_icloglock); xlog_state_do_iclog_callbacks xlog_state_iodone_process_iclog xlog_state_set_callback last_sync_lsn = iclog->ic_header.h_lsn spin_unlock(&log->l_icloglock); ====>AIL is empty and get tail lsn for new iclog xlog_cil_process_committed xlog_cil_committed xfs_trans_committed_bulk(ctx->start_lsn) xfs_log_item_batch_insert(commit_lsn) xlog_state_clean_iclog(log, iclog) spin_lock(&log->l_icloglock); spin_unlock(&log->l_icloglock); Fix is simple, updates the l_last_sync_lsn with it's first ctx start lsn when commit iclog buffer IO completion. Even if the above happens, the iclog will be replayed as well.

[PATCH V4 OLK-6.6] fs/dirty_pages: dump the number of dirty pages for each inode
by Zizhi Wo 09 Jan '24

09 Jan '24

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I8OHM4?from=project-issue CVE: NA ---------------------------------------- In order to analyse the IO performance when using buffer IO, it's useful to obtain the number of dirty pages for each inode in the filesystem. This feature depends on 'CONFIG_DIRTY_PAGES'. It creates 3 interfaces by using procfs. /proc/dirty/buffer_size for buffer allocation and release, /proc/dirty/page_threshold to filter result and /proc/dirty/dirty_list to get dirty pages.

[PATCH OLK-6.6 0/2] Some simple extensions of the kfence feature
by Ze Zuo 09 Jan '24

09 Jan '24

This patchset supports the following two features: 1. The number of kfence objects is a key factor to balance kfence bug detection capabilities and performance loss, and often needs to be optimized according to actual business scenarios. The number of kfence objects can be dynamically configured kfence.num_objects cmdline, so as to reduce the release of kernel versions in actual use, thereby reducing costs. 2. The kfence feature under arm64 supports dynamic opening after system startup, which will turn all the kernel memblock memory into page-mapped mapping and increase the memory overhead, in order to save the page table memory usage, only the kfence pool supports page-mapped mapping, which can be enabled at kernel startup by setting kfence.sample _interval=-1 at kernel startup to enable the dynamic on capability, at this time it will allocate memory for kfence by default. The kfence will be allocated memory by default. Subsequent dynamic enablement and disabling will no longer consume additional memory. This feature has been tested under ARM64, x86_64 and ARM architectures, and the Kfence Kunit test results are consistent with the native ones. ChangeLog: - Add config kfence_must_early_init to perform code isolation for non-functional purposes. - Some minor changes about document, no functional changes. Ze Zuo (2): kfence: Add a module parameter to adjust kfence objects arm64: kfence: scale sample_interval to support early init for kfence.

by Jinjiang Tu 09 Jan '24

09 Jan '24

This series patches add swap control for memory cgroup. Patch[1] add page type in memory.reclaim interface to support reclaim anon pages. Patch[3] add memory.force_swapin interface to support swap back pages proactively. Patch[4-6] add memory.swapfile interface to limit available swap device for memory cgroup. Patch[7] add memory.swap.max interface to limit usage of swap for memory cgroup. Jinjiang Tu (1): memcg: make sysctl registration more extensible Liu Shixin (7): memcg: add page type to memory.reclaim interface memcg: introduce memcg swap qos feature memcg: introduce per-memcg swapin interface memcg: add restrict to swap to cgroup1 mm/swapfile: introduce per-memcg swapfile control mm: swap_slots: add per-type slot cache config: enable memcg swap qos for x86_64 and arm64 by default zhaoxiaoqiang11 (1): memcg/swap: add ability to disable memcg swap .../admin-guide/cgroup-v1/memory.rst | 4 + Documentation/admin-guide/cgroup-v2.rst | 10 +- arch/arm64/configs/openeuler_defconfig | 1 + arch/x86/configs/openeuler_defconfig | 1 + include/linux/memcontrol.h | 35 ++ include/linux/mm.h | 4 + include/linux/swap.h | 12 +- include/linux/swap_slots.h | 2 +- init/Kconfig | 9 + mm/madvise.c | 31 +- mm/memcontrol.c | 493 +++++++++++++++++- mm/swap_slots.c | 151 +++++- mm/swapfile.c | 97 +++- mm/vmscan.c | 9 + 14 files changed, 810 insertions(+), 49 deletions(-) -- 2.25.1
