fsck.ubifs: fix platform dependant ino_t and loff_t formatting

2026-04-13T05:32:41+00:00

On architectures such as armv7-a, ino_t and loff_t are unsigned long long rather than unsigned long. In such cases, the printf format specifier "%lu" is not appropriate and causes an incorrect address offset. mtd-utils/ubifs-utils/fsck.ubifs/problem.c:224 log_out(c, "problem: %s, ino %lu, unreachable dentry %s, type %s%s", problem->desc, ifp->file->inum, c->encrypted && !ifp->file->ino.is_xattr ? "" : dent_node->name, ubifs_get_type_name(dent_node->type), key_type(c, &dent_node->key) == UBIFS_XENT_KEY ? "(xattr)" : ""); fsck.ubifs[484] (/dev/ubi0_0,danger mode): problem: Dentry is unreachable, ino 917, unreachable dentry (null), type checksum_typefile Furthermore, running fsck.ubifs with the --debug=4 option will almost certainly cause a SEGV at the following point. mtd-utils/ubifs-utils/fsck.ubifs/check_files.c:103 dbg_fsck("construct file(%lu) for %s node, TNC location %d:%d, in %s", inum, ubifs_get_key_name(key_type(c, key)), sn->lnum, sn->offs, c->dev_name); To ensure functionality regardless of environment, cast ino_t to unsigned long, since it will never be more than 4 bytes. For loff_t, use %lld and cast accordingly. Signed-off-by: Yuta Hayama Signed-off-by: Tomas Alvarez Vanoli Reviewed-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

fsck.ubifs: Handle disconnected files

2024-11-11T09:32:46+00:00

This is the 17/18 step of fsck. Recover disconnected files into lost+found. If there is no free space left to recover the disconnected files, fsck may delete the files to make filesystem be consistent. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

fsck.ubifs: Check and create the lost+found

2024-11-11T09:32:46+00:00

This is the 16/18 step of fsck. Check whether the lost+found is existed, create a new one if it is not found. This step makes sure that disconnected file can be recovered under the lost+found. Signed-off-by: Huang Xiaojia Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer
