Currently f2fs stats are only available from /d/f2fs/status. This patch adds some of the f2fs stats to sysfs so that they are accessible even when debugfs is not mounted. The following sysfs nodes are added: -/sys/fs/f2fs/<disk>/free_segments -/sys/fs/f2fs/<disk>/cp_foreground_calls -/sys/fs/f2fs/<disk>/cp_background_calls -/sys/fs/f2fs/<disk>/gc_foreground_calls -/sys/fs/f2fs/<disk>/gc_background_calls -/sys/fs/f2fs/<disk>/moved_blocks_foreground -/sys/fs/f2fs/<disk>/moved_blocks_background -/sys/fs/f2fs/<disk>/avg_vblocks Signed-off-by:

This patch merges the sysfs node documentation present in Documentation/filesystems/f2fs.txt and Documentation/ABI/testing/sysfs-fs-f2fs and deletes the duplicate information from Documentation/filesystems/f2fs.txt. This is to prevent having to update both files when a new sysfs node is added for f2fs. The patch also makes minor formatting changes to Documentation/ABI/testing/sysfs-fs-f2fs. Signed-off-by:

Without any form of coordination, any case where multiple allocations from the same mempool are needed at a time to make forward progress can deadlock under memory pressure. This is the case for struct bio_post_read_ctx, as one can be allocated to decrypt a Merkle tree page during fsverity_verify_bio(), which itself is running from a post-read callback for a data bio which has its own struct bio_post_read_ctx. Fix this by freeing first bio_post_read_ctx before calling fsverity_verify_bio(). This works because verity (if enabled) is always the last post-read step. This deadlock can be reproduced by trying to read from an encrypted verity file after reducing NUM_PREALLOC_POST_READ_CTXS to 1 and patching mempool_alloc() to pretend that pool->alloc() always fails. Note that since NUM_PREALLOC_POST_READ_CTXS is actually 128, to actually hit this bug in practice would require reading from lots of encrypted verity files at the same time. But it's theoretically possible, as N available objects doesn't guarantee forward progress when > N/2 threads each need 2 objects at a time.

As Youling reported in mailing list: https://www.linuxquestions.org/questions/linux-newbie-8/the-file-system-f2fs-is-broken-4175666043/ https://www.linux.org/threads/the-file-system-f2fs-is-broken.26490/ There is a test case can corrupt f2fs image: - dd if=/dev/zero of=/swapfile bs=1M count=4096 - chmod 600 /swapfile - mkswap /swapfile - swapon --discard /swapfile The root cause is f2fs_swap_activate() intends to return zero value to setup_swap_extents() to enable SWP_FS mode (swap file goes through fs), in this flow, setup_swap_extents() setups swap extent with wrong block address range, result in discard_swap() erasing incorrect address. Because f2fs_swap_activate() has pinned swapfile, its data block address will not change, it's safe to let swap to handle IO through raw device, so we can get rid of SWAP_FS mode and initial swap extents inside f2fs_swap_activate(), by this way, later discard_swap() can trim in right address range.

This patch tries to support compression in f2fs. - New term named cluster is defined as basic unit of compression, file can be divided into multiple clusters logically. One cluster includes 4 << n (n >= 0) logical pages, compression size is also cluster size, each of cluster can be compressed or not. - In cluster metadata layout, one special flag is used to indicate cluster is compressed one or normal one, for compressed cluster, following metadata maps cluster to [1, 4 << n - 1] physical blocks, in where f2fs stores data including compress header and compressed data. - In order to eliminate write amplification during overwrite, F2FS only support compression on write-once file, data can be compressed only when all logical blocks in file are valid and cluster compress ratio is lower than specified threshold. - To enable compression on regular inode, there are three ways: * chattr +c file * chattr +c dir; touch dir/file * mount w/ -o compress_extension=ext; touch file.ext Compress metadata layout: [Dnode Structure] +-----------------------------------------------+ | cluster 1 | cluster 2 | ......... | cluster N | +-----------------------------------------------+ . . . . . . . . .

In low memory scenario, we can allocate multiple bios without submitting any of them. - f2fs_write_checkpoint() - block_operations() - f2fs_sync_node_pages() step 1) flush cold nodes, allocate new bio from mempool - bio_alloc() - mempool_alloc() step 2) flush hot nodes, allocate a bio from mempool - bio_alloc() - mempool_alloc() step 3) flush warm nodes, be stuck in below call path - bio_alloc() - mempool_alloc() - loop to wait mempool element release, as we only reserved memory for two bio allocation, however above allocated two bios may never be submitted. So we need avoid using default bioset, in this patch we introduce a private bioset, in where we enlarg mempool element count to total number of log header, so that we can make sure we have enough backuped memory pool in scenario of allocating/holding multiple bios.

To catch f2fs bugs in write pointer handling code for zoned block devices, check write pointers of non-open zones that current segments do not point to. Do this check at mount time, after the fsync data recovery and current segments' write pointer consistency fix. Or when fsync data recovery is disabled by mount option, do the check when there is no fsync data. Check two items comparing write pointers with valid block maps in SIT. The first item is check for zones with no valid blocks. When there is no valid blocks in a zone, the write pointer should be at the start of the zone. If not, next write operation to the zone will cause unaligned write error. If write pointer is not at the zone start, reset the write pointer to place at the zone start. The second item is check between the write pointer position and the last valid block in the zone. It is unexpected that the last valid block position is beyond the write pointer. In such a case, report as a bug. Fix is not required for such zone, because the zone is not selected for next write operation until the zone get discarded. Signed-off-by:

On sudden f2fs shutdown, write pointers of zoned block devices can go further but f2fs meta data keeps current segments at positions before the write operations. After remounting the f2fs, this inconsistency causes write operations not at write pointers and "Unaligned write command" error is reported. To avoid the error, compare current segments with write pointers of open zones the current segments point to, during mount operation. If the write pointer position is not aligned with the current segment position, assign a new zone to the current segment. Also check the newly assigned zone has write pointer at zone start. If not, reset write pointer of the zone. Perform the consistency check during fsync recovery. Not to lose the fsync data, do the check after fsync data gets restored and before checkpoint commit which flushes data at current segment positions. Not to cause conflict with kworker's dirfy data/node flush, do the fix within SBI_POR_DOING protection. Signed-off-by:
