The orphan inode should only be removed from the orphan list after the extent tree update is complete. This ensures that if a crash occurs in the middle of extent tree updates, we won&#39;t leave stale blocks beyond EOF.</p> <p>This patch also changes the logic for updating the inode size and removing orphan, making it similar to ext4_dio_write_end_io(). Both operations are performed only when everything looks good.</p> <p>Finally, thanks to Jans and Joseph for providing the bug fix prototype and suggestions.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>ocfs2: split transactions in dio completion to avoid credit exhaustion</p> <p>During ocfs2 dio operations, JBD2 may report warnings via following call trace: ocfs2_dio_end_io_write ocfs2_mark_extent_written ocfs2_change_extent_flag ocfs2_split_extent ocfs2_try_to_merge_extent ocfs2_extend_rotate_transaction ocfs2_extend_trans jbd2__journal_restart start_this_handle output: JBD2: kworker/6:2 wants too many credits credits:5450 rsv_credits:0 max:5449</p> <p>To prevent exceeding the credits limit, modify ocfs2_dio_end_io_write() to handle extents in a batch of transaction.</p> <p>Additionally, relocate ocfs2_del_inode_from_orphan().
