UBIFS: endian handling fixes and annotations
Noticed by sparse: fs/ubifs/file.c:75:2: warning: restricted __le64 degrades to integer fs/ubifs/file.c:629:4: warning: restricted __le64 degrades to integer fs/ubifs/dir.c:431:3: warning: restricted __le64 degrades to integer This should be checked to ensure the ubifs_assert is working as intended, I've done the suggested annotation in this patch. fs/ubifs/sb.c:298:6: warning: incorrect type in assignment (different base types) fs/ubifs/sb.c:298:6: expected int [signed] [assigned] tmp fs/ubifs/sb.c:298:6: got restricted __le64 [usertype] <noident> fs/ubifs/sb.c:299:19: warning: incorrect type in assignment (different base types) fs/ubifs/sb.c:299:19: expected restricted __le64 [usertype] atime_sec fs/ubifs/sb.c:299:19: got int [signed] [assigned] tmp fs/ubifs/sb.c:300:19: warning: incorrect type in assignment (different base types) fs/ubifs/sb.c:300:19: expected restricted __le64 [usertype] ctime_sec fs/ubifs/sb.c:300:19: got int [signed] [assigned] tmp fs/ubifs/sb.c:301:19: warning: incorrect type in assignment (different base types) fs/ubifs/sb.c:301:19: expected restricted __le64 [usertype] mtime_sec fs/ubifs/sb.c:301:19: got int [signed] [assigned] tmp This looks like a bugfix as your tmp was a u32 so there was truncation in the atime, mtime, ctime value, probably not intentional, add a tmp_le64 and use it here. fs/ubifs/key.h:348:9: warning: cast to restricted __le32 fs/ubifs/key.h:348:9: warning: cast to restricted __le32 fs/ubifs/key.h:419:9: warning: cast to restricted __le32 Read from the annotated union member instead. fs/ubifs/recovery.c:175:13: warning: incorrect type in assignment (different base types) fs/ubifs/recovery.c:175:13: expected unsigned int [unsigned] [usertype] save_flags fs/ubifs/recovery.c:175:13: got restricted __le32 [usertype] flags fs/ubifs/recovery.c:186:13: warning: incorrect type in assignment (different base types) fs/ubifs/recovery.c:186:13: expected restricted __le32 [usertype] flags fs/ubifs/recovery.c:186:13: got unsigned int [unsigned] [usertype] save_flags Do byteshifting at compile time of the flag value.
