filesystem needs foreground checking (usually at boot time) or
can defer to background checking (after the system is up and running).
See the manual page, fsck_ffs(8), for details on the -F and -B options.
These options are primarily intended for use by the fsck front end.
All output is directed to stdout so that the output is coherent
when redirected to a file or a pipe. Unify the code with the fsck
front end that allows either a device or a mount point to be
specified as the argument to be checked.
1) Set the FS_NEEDSFSCK flag when unexpected problems are encountered.
2) Clear the FS_NEEDSFSCK flag after a successful foreground cleanup.
3) Refuse to run in background when the FS_NEEDSFSCK flag is set.
4) Avoid taking and removing a snapshot when the filesystem is already clean.
5) Properly implement the force cleaning (-f) flag when in preen mode.

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.
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.

in-core pointers to summary information. An array in this region
(fs_csp) could overflow on filesystems with a very large number of
cylinder groups (~16000 on i386 with 8k blocks). When this happens,
other fields in the superblock get corrupted, and fsck refuses to
check the filesystem.
Solve this problem by replacing the fs_csp array in 'struct fs'
with a single pointer, and add padding to keep the length of the
128-byte region fixed. Update the kernel and userland utilities
to use just this single pointer.
With this change, the kernel no longer makes use of the superblock
fields 'fs_csshift' and 'fs_csmask'. Add a comment to newfs/mkfs.c
to indicate that these fields must be calculated for compatibility
with older kernels.

utilities which use bits of fsck_ffs - namely quotacheck and fsdb.
In depth, utilities.c contains blockcheck() which is needed by both,
but also a slew of routines which require bits of the FFS code to be
compiled in. This breaks the fs-specific and non-fs-specific code
up into two files (well, blockcheck() is the only routine in utilities.c,
that'll change later) which makes building fsck_ffs, quotacheck and
fsdb work yet again.
(You won't find commits to fsdb and quotacheck here before I haven't
committed the post-fsck-wrappers version of them yet.)

The beginnings of the fsck wrappers stuff from NetBSD. This particular commit
brings a newly repo-copied sbin/fsck_ffs/ (from sbin/fsck/) into fsck wrappers
mode.
A quick overview (the code reflects this):
* Documentation changed to reflect fsck_ffs instead of fsck
* Simply acts on a single filesystem, doesn't try to do any multiple filesystem
magic - this is done by the fsck wrappers now
And then specific to fsck_ffs:
* link to /sbin/fsck_4.2bsd and /sbin/fsck_ufs. This is because right now
the filesystem is of type ufs not ffs, and that during autodetection the
labeltype rather than the VFS type is used - this is because when doing
an autodetection of filesystem type in the fsck wrapper program, it does
not have any link between label type (4.2bsd, vinum, etc) and VFS string.
Note that this shouldn't break a build since the required buildworld Makefile
magic and import of the fsck wrapper code into src/sbin/fsck/ will happen
in a seperate commit.
which sets the inoinfo's i_parent and i_dotdot to 0, but they never get
set to ROOTINO. This means that propagate will never find lost+found and
its descendents, subdirectories will remain DSTATE (instead of DFOUND)
even though they *are* correctly linked in, and pass4.c will try to
clear them unsuccessfully, thinking that there is no link count from the
DSTATE directory's parent. The result is that you need to run fsck twice
and get link count increasing errors (which are unexpected and fatal
when running in preen mode). The fix is to set i_parent and i_dotdot to
"parent" after the second cacheino() call in dir.c:allocdir().

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.
