reiserfs: The last commit

2024-10-21T14:29:38+00:00

Deprecation period of reiserfs ends with the end of this year so it is time to remove it from the kernel. Acked-by: Darrick J. Wong Acked-by: Christian Brauner Signed-off-by: Jan Kara

reiserfs: fix uninit-value in comp_keys

2023-12-28T10:56:52+00:00

The cpu_key was not initialized in reiserfs_delete_solid_item(), which triggered this issue. Reported-and-tested-by: Signed-off-by: Edward Adam Davis Link: https://lore.kernel.org/r/tencent_9EA7E746DE92DBC66049A62EDF6ED64CA706@qq.com Signed-off-by: Christian Brauner

reiserfs: convert to ctime accessor functions

2023-07-24T08:30:04+00:00

In later patches, we're going to change how the inode's ctime field is used. Switch to using accessor functions instead of raw accesses of inode->i_ctime. Signed-off-by: Jeff Layton Reviewed-by: Jan Kara Message-Id: <20230705190309.579783-70-jlayton@kernel.org> Signed-off-by: Christian Brauner

reiserfs: replace ll_rw_block()

2022-09-12T03:26:07+00:00

ll_rw_block() is not safe for the sync read/write path because it cannot guarantee that submitting read/write IO if the buffer has been locked. We could get false positive EIO after wait_on_buffer() in read path if the buffer has been locked by others. So stop using ll_rw_block() in reiserfs. We also switch to new bh_readahead_batch() helper for the buffer array readahead path.

fs/buffer: Combine two submit_bh() and ll_rw_block() arguments

2022-07-14T18:14:32+00:00

Both submit_bh() and ll_rw_block() accept a request operation type and request flags as their first two arguments. Micro-optimize these two functions by combining these first two arguments into a single argument. This patch does not change the behavior of any of the modified code.

reiserfs: check directory items on read from disk

2021-07-16T10:36:51+00:00

While verifying the leaf item that we read from the disk, reiserfs doesn't check the directory items, this could cause a crash when we read a directory item from the disk that has an invalid deh_location. This patch adds a check to the directory items read from the disk that does a bounds check on deh_location for the directory entries. Any directory entry header with a directory entry offset greater than the item length is considered invalid.
