o Separate the kernel stuff from the Yarrow algorithm. Yarrow is now
well contained in one source file and one header.
o Replace the Blowfish-based crypto routines with Rijndael-based ones.
(Rijndael is the new AES algorithm). The huge improvement in
Rijndael's key-agility over Blowfish means that this is an
extremely dramatic improvement in speed, and makes a heck of
a difference in its (lack of) CPU load.
o Clean up the sysctl's. At BDE's prompting, I have gone back to
static sysctls.
o Bug fixes. The streamlining of the crypto stuff enabled me to
find and fix some bugs. DES also found a bug in the reseed routine
which is fixed.
o Change the way reseeds clear "used" entropy. Previously, only the
source(s) that caused a reseed were cleared. Now all sources in the
relevant pool(s) are cleared.
o Code tidy-up. Mostly to make it (nearly) 80-column compliant.
enable all harvesting options by default since having them on for
devices not present doesn't hurt anything. Leave them on by default
since for the most part they are not producing noticable slowdown,
and are about to get a lot more efficient.
Re-order part of the cheesy entropy process in preparation for
its complete removal.
Use mchain API to work with mbuf chains.
Do not depend on INET and IPX options.
Allocate ncp_rq structure dynamically to prevent possible stack overflows.
Let ncp_request() dispose control structure if request failed.
Move all NCP wrappers to ncp_ncp.c file and all NCP request processing
functions to ncp_rq.c file.
Improve reconnection logic.
Misc style fixes.

adjustment method reading the chip clock year register to note that
anything less than 70 means we're past the year 2000.

mdconfig printing "md0" to standard output.

reference count was transferred to the new object, but both the
new and the old map entries had pointers to the new object.
Correct this by transferring the second reference.
This fixes a panic that can occur when mmap(2) is used with the
MAP_INHERIT flag.

TIP: if offset is not needed, the -offset clause may be omitted.
get it in the CVS logs. This pertains to rev 1.30 (and the MFC of it):
Space optimization forces the kernel to always use fragments to store
parts of file, rather than using an entire block when less than an
entire block has been written. This forces files to be as small as
they can be at the minor cost of time to do all the fussy stuff. The
cpio image that we put on the disk was so close to filling the disk
exactly that this minor minor difference made a big difference. The
system changed things to time optmization on the first write. When
the end of file was hit, it tried to allocate a full block (4k), but
there was only 3k left on the disk (since you get only 1407 blocks on
a 1.44 floppy) so it failed. So this change nails the space
optmiziation in place for the whole operation.

variable instead of MAXTTL constant as the default time-to-live
value for outgoing IP packets all over the place, as we already
do this for TCP and UDP.
