1904591561 Fsck_ffs did not properly range-check the inode 'di_size'
field, so it was possible for a filesystem marked clean by fsck_ffs
to cause kernel crashes later when mounted. This could occur when
fsck_ffs was used to repair a badly corrupted filesystem.

As pointed out by bde, it is not sufficient to restrict di_size to
just the superblock fs_maxfilesize limit. The use of 32-bit logical
block numbers (both in fsck and the kernel) induces another file
size limit which is usually lower than fs_maxfilesize. Also, the
old 4.3BSD filesystem does not have fs_maxfilesize initialised.

Following this change, fsck_ffs will enforce exactly the same
file size limits as are used by the kernel.

3e3c84c80c Add a simple SIGINFO handler to fsck_ffs. Shortly after receipt of
a SIGINFO (normally via Ctrl-T), a line will be output indicating
the current phase number and progress information relevant to the
current phase.

64fa502890 Ensure that block and character devices as well as fifo's and sockets
all have zero length. A non-zero length panic's the kernel when one
of these is deleted.

61ae57db56 Teach fsck about snapshot files. These changes should have no
effect on operation of fsck on filesystems without snapshots.
If you get compilation errors, be sure that you have copies of
/usr/include/sys/mount.h (1.94), /usr/include/sys/stat.h (1.21),
and /usr/include/ufs/ffs/fs.h (1.16) as of July 4, 2000 or later.

This exactly matches Kirks sources imported under the
Tag MCKUSICK2. These are as supplied by kirk with one small
change needed to compile under freeBSD.

Some FreeBSD patches will be added back, though many have been
added to Kirk's sources already.

07c3866a6e Two fixes from the NetBSD group (Charles Hannum):
1) dir.c: get byte order right in mkentry()
2) pass1.c: When doing -c2 conversion, do secsize reads for a symlink -
   not doing so was causing the conversion to fail because the device
   driver can't deal with short reads.
