-Subject: [PATCH] ubifs: Handle re-linking of inodes correctly while recovery
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-UBIFS's recovery code strictly assumes that a deleted inode will never
-come back, therefore it removes all data which belongs to that inode
-as soon it faces an inode with link count 0 in the replay list.
-Before O_TMPFILE this assumption was perfectly fine. With O_TMPFILE
-it can lead to data loss upon a power-cut.
-
-Consider a journal with entries like:
-0: inode X (nlink = 0) /* O_TMPFILE was created */
-1: data for inode X /* Someone writes to the temp file */
-2: inode X (nlink = 0) /* inode was changed, xattr, chmod, … */
-3: inode X (nlink = 1) /* inode was re-linked via linkat() */
-
-Upon replay of entry #2 UBIFS will drop all data that belongs to inode X,
-this will lead to an empty file after mounting.
-
-As solution for this problem, scan the replay list for a re-link entry
-before dropping data.
-
-Fixes: 474b93704f32 ("ubifs: Implement O_TMPFILE")
