7578c6ab98 Additions to run checks on live filesystems. This change will not
affect current systems until fsck is modified to use these new
facilities. To try out this change, set the fsck passno to zero
in /etc/fstab to cause the filesystem to be mounted without running
fsck, then run `fsck_ffs -p -B <filesystem>' after the system has
been brought up multiuser to run a background cleanup on <filesystem>.
Note that the <filesystem> in question must have soft updates enabled.

142d8d2f40 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.

e50342e665 Yesterday I had to fix a badly broken disk, and found that fsck kept dying:
DIR I=64512 CONNECTED. PARENT WAS I=4032
  fsck: cannot find inode 995904

fsdb found the inodes with no problem:

  fsdb (inum: 64512)> inode 995904
  current inode: directory
  I=995904 MODE=40777 SIZE=512
        MTIME=Feb 14 15:27:07 2000 [0 nsec]
        CTIME=Feb 14 15:27:07 2000 [0 nsec]
        ATIME=Feb 24 10:31:58 2000 [0 nsec]
  OWNER=nobody GRP=nobody LINKCNT=4 FLAGS=0 BLKCNT=2 GEN=38a41386
  Direct blocks: 8094568 0 0 0 0 0 0 0 0 0 0 0
  Indirect blocks:  0 0 0

The problem turns out to be a program logic error in fsck.  It stores
directory inodes internally in hash lists, using the number of
directories to form the hash key:

        inpp = &inphead[inumber % numdirs];

Elsewhere, however, it increments numdirs when it finds unattached
directories.  I've made the following fix, which solved the problem in
the case in hand.

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.

db398a8bd4 Fixed overflow in chkrange(). Some out of bounds block numbers,
e.g. -1, were not detected.  Use a bulletproof check that doesn't
depend on special properties of the args or the limit.

10e1c2d28a patch up some "int *" vs. "time_t *" (long) mismatches. They could be
nasty if sizeof(int) != sizeof(long).

780a5c1ec1 Merge from Lite2. Note that Lite2 has it's own filesystem clean check
skipping code that overrides ours sooner.  One should be eliminated,
but for now it works.

47ceb63687 Fix the case where fsck would not see sparse directories and the kernel would
panic. If such a thing is fixed fsck needs a rerun (and bugs the user to do
so).
