what is currently in -CURRENT, but should hopefully be the last time
any application breakage is caused there. As soon as any major
inconveniences are removed, the definition of the in-kernel struct
ucred should be conditionalized upon defined(_KERNEL).
This also changes struct export_args to remove dependency on the
constantly-changing struct ucred, as well as limiting the bounds
of the size fields to the correct size. This means: a) mountd and
friends won't break all the time, b) mountd and friends won't crash
the kernel all the time if they don't know what they're doing wrt
actual struct export_args layout.

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.

(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

with older kernels.

flags related to ECN are now included in tcp.h for reference, although
we don't currently implement TCP+ECN.
o To use this fix without completely rebuilding, it is sufficient to copy
ip_fw.h and tcp.h into your appropriate include directory, then rebuild
the ipfw kernel module, and ipfw tool, and install both. Note that a
mismatch between module and userland tool will result in incorrect
installation of firewall rules that may have unexpected effects. This
is an MFC candidate, following shakedown. This bug does not appear

This makes "/dev/ad0s1a" and "/dev/ad0s2a" appear to both reside

good solution would be to look for passes larger than 1 until no

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.

related patches. These include:
* Mode page editting can be scripted. This involves two
things: first, if stdin is not a tty, changes are read from
stdin rather than invoking $EDITOR. Second, and more
importantly, not all modepage entries must be included in the
change set. This means that camcontrol can now gracefully handle
more intrusive editting from the $EDITOR, including removal or
rearrangement of lines. It also means that you can do stuff
like:
# echo "WCE: 1" | camcontrol modepage da3 -m 8 -e
# newfs /dev/da3
# echo "WCE: 0" | camcontrol modepage da3 -m 8 -e
* Range-checking on user-supplied input values. modeedit.c now
uses the field width specifiers to determine the maximum
allowable value for a field. If the user enters a value larger
than the maximum, it clips the value to the max and warns the
user. This also involved patching cam_cmdparse.c to be more
consistent with regards to the "count" parameter to arg_put
(previously is was the length of strings and 1 for all integral
types). The cam_cdbparse(3) man page was also updated to reflect
the revised semantics.
* In the process, I removed the 64 entry limit on mode pages (not
that we were even close to hitting that limit). This was a nice
side-effect of the other changes.
* Technically, the new mode editting functionality allows editting
of character array entries in mode pages (type 'c' or 'z'),
however since buff_encode doesn't grok them it is currently
useless.
* Camcontrol gained two new options related to mode pages: -l and
-b. The former lists all available mode pages for a given
device. The latter forces mode page display in binary format
(the default when no mode page definition was found in
scsi_modes).
* Added support for mode page names to scsi_modes. Allows names to
be displayed alongside mode numbers in the mode page
listing. Updated scsi_modes to use the new functionality. This
also adds the semicolon into the scsi_modes syntax as an
optional mode page definition terminator. This is needed to name
pages without providing a page format definition.
* Updated scsi_all.h to include a structure describing mode page
headers.
* Added $FreeBSD$ line to scsi_modes.
