Remove ulfs_daddr_t.

Use daddr_t, not ulfs_daddr_t, as the latter's 32 bits wide.
Don't use either for on-disk items.
Part 2 of 3.

Don't use either for on-disk items.
Part 1 of 3.

Part two of dinodes; use the same union everywhere.
(previously the ufs-derived code had things set up slightly different)

Remove a bunch of associated mess.

Hack up dinode usage to be 64 vs. 32 as needed. Part 1.

(This part changes the native lfs code; the ufs-derived code already
has 64 vs. 32 logic, but as aspects of it are unsafe, and don't

(This part changes the native lfs code; the ufs-derived code already
has 64 vs. 32 logic, but as aspects of it are unsafe, and don't
entirely interoperate cleanly with the lfs 64/32 stuff, pass 2 will be
rehashing that.)

Provide 32-bit and 64-bit versions of FINFO.

This also entailed sorting out part of struct segment, as that
contains a pointer into the current FINFO data.

Make 32-bit and 64-bit versions of SEGSUM.
Also fix some of the FINFO handling as it's closely entangled.

Revert previous; it doesn't work because all the lfs tools
promiscuously .PATH in each other's source files, and I haven't the
time or patience to deal with it tonight.

G/C my_vpanic().

hi ad@

ufs -> ulfs for fsck_lfs.

Remove clause 3 and 4 from TNF licenses

Various improvements to fsck_lfs, to wit:

* Add lfs_balloc capability to the lfs library.
* Extend the Ifile if we run out of free inodes when creating lost+found.
* Don't roll forward if we have al

Various improvements to fsck_lfs, to wit:

* Add lfs_balloc capability to the lfs library.
* Extend the Ifile if we run out of free inodes when creating lost+found.
* Don't roll forward if we have allocated a lost+found, to avoid
conflicts when adding new files in roll-forward.
* Make some messages slightly more verbose (e.g. include inode number,
and use pwarn() instead of printf() so the messages include the device
name when preening).
* Change superblock detection/avoidance to use the offset table in the
primary superblock, rather than looking at the contents.
* Be more verbose about various operations when passed the -d flag,
especially roll-forward.
* Be more careful about dirops during roll forward, since the cleaner can
sometimes write blocks from dirop vnodes. Detect and avoid this problem.
* Always check the free list, even if given -i; if we're going to write
it we have to check it first.
* Mark inodes dirty when blocks are found during roll forward, so the
inodes are written with the new block locations.
* Update size of inodes if blocks beyond EOF are found during roll
forward.
* Fix segment accounting for blocks and inodes found during roll
forward.
* Report statistics on roll forward: how many new/deleted/moved files
and how many updated blocks (or "nothing new").
* Don't care if the device being checked is really a device, if we have
been passed the -f flag (to facilitate automated testing).
* When writing to the disk, use the current time in the segment headers
rathern than time 0.
* When passed the -i flag, locate the partial segment containing the
Ifile inode and use that to calculate lfs_offset, lfs_curseg,
lfs_nextseg. (Again for automated testing.)

rename lfs.h to lfs_user.h so that it does not conflict.
