da22d85db7 Ignore EXT4 'kbytes written' field when validating alternate superblock. 2019-03-31 13:16:52 +00:00
mlelstv
25aaa28e7c No longer rely on data in disklabel to deduce alternate superblock 
positions from block size. Instead use the same defaults as newfs_ext2fs.

Side effect is that fsck_ext2fs now works with wedges.

bbddb1419d Ignore recorded last mount point when validating alternate superblocks. 
Compute log_bsize correctly. This fixes computation of alternate
superblock addresses.

d2d8cddee2 divorce list of features supported by fsck_ext2fs from the kernel; 
while kernel might support e.g. extents, extra_isize or dir_nlink,
fsck could actually have no idea about the features

2737439da3 fsbtodb() -> FFS_FSBTODB(), EXT2_FSBTODB(), or MFS_FSBTODB() 
dbtofsb() -> FFS_DBTOFSB() or EXT2_DBTOFSB()

(Christos already did the lfs ones a few days back)

f1333577b5 Rename ambiguous macros: 
MAXDIRSIZE -> UFS_MAXDIRSIZE or LFS_MAXDIRSIZE
   NINDIR -> FFS_NINDIR, EXT2_NINDIR, LFS_NINDIR, or MFS_NINDIR
   INOPB -> FFS_INOPB, LFS_INOPB
   INOPF -> FFS_INOPF, LFS_INOPF
   blksize -> ffs_blksize, ext2_blksize, or lfs_blksize
   sblksize -> ffs_blksize

These are not the only ambiguously defined filesystem macros, of
course, there's a pile more. I may not have found all the ambiguous
definitions of blksize(), too, as there are a lot of other things
called 'blksize' in the system.

dcd34a91c5 Stuff UFS_ in front of a few of ufs's symbols to reduce namespace 
pollution. Specifically:
   ROOTINO -> UFS_ROOTINO
   WINO -> UFS_WINO
   NXADDR -> UFS_NXADDR
   NDADDR -> UFS_NDADDR
   NIADDR -> UFS_NIADDR
   MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN
   MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency)

Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have
the same values in ext2fs and ffs.

No functional change intended.

f592533590 - add a sanity check for e2fs_inode_size in readsb() 
- use EXT2_DINODE_SIZE() rather than sizeof(struct ext2fs_dinode) or
  struct ext2fs_dinode array/pointer to see e2fs_ipb and inode offsets

481ad7b03a errexit() now provides the trailing \n (since fsck_ffs assumed that 
from a conversion from err(3)), so "make it so".

d53c382dbf Add support for large files (>2GB). 
Allow conversion of old filesystems to use this,
if they are already at revision 1.

There probably should be an option to turn revision 0 to revision 1.

here) and a new field that can be different in the master superblock and
its first copy. From Tim Shepard.

7052d78b8d Ext2 metadata are always stored on disk in little-endian byte order, 
so do byte-swapping on big-endian system. The byte-swap routines are in
fsck/bswap.c because they will also be used in fsck_ffs in future.
Tested on i386 and sparc.
