This work was based on kame-20010528-freebsd43-snap.tgz and some
critical problem after the snap was out were fixed.
There are many many changes since last KAME merge.
TODO:
- The definitions of SADB_* in sys/net/pfkeyv2.h are still different
from RFC2407/IANA assignment because of binary compatibility
issue. It should be fixed under 5-CURRENT.
- ip6po_m member of struct ip6_pktopts is no longer used. But, it
is still there because of binary compatibility issue. It should
be removed under 5-CURRENT.

Future remote filesystem types should be added to remote_fstypes, which
is a whitespace-delimited list of type:description pairs.
The specific problem this fixes right now is that smbfs mounts described
in /etc/ftsab were failing.
Make the default setting YES for now to get some experience with it.
Note: If people starts seeing disk errors because of this then it
should not be backed.
With a small disk being 20GB these days, chances are pretty good that
an ailing sector will not be read while still being recoverable by
the drive.
Diskcheck daemon will read disks in the background at a low rate and
that way give the diskdrive a chance to detect and correct soft read
errors before they become hard errors.

fsck checking. Applying these changes (typically via mergemaster)
will cause your system to start running background checks on all
your soft update enabled filesystems (provided that you have
a kernel with the required functionality, e.g., one built since
the end of April). Please report any and all problems to
mckusick@mckusick.com (not mckusick@freebsd.org which I read
infrequently). See the comment above the fsck command in /etc/rc
for instructions on how to disable background checking should it
cause you too much trouble.
Several FAQs:
1) Can I reboot before the background checks are done?
Ans) Yes, when the system restarts the checks will pick up
where they left off.
2) Can a crash during checking corrupt my filesystem?
Ans) No, recovered resources are returned to the system using soft
updates which ensure that the freeing is done in a safe order.
3) How will I know if any background checks are being done?
Ans) Filesystems that are to be checked in background will be listed
as `DEFER FOR BACKGROUND CHECKING' at the usual fsck check time
during system startup.
4) What happens to the output of the background checks?
Ans) It is sent to syslog `daemon' facility log level `notice'.
5) When will this feature be available in the 4.X kernel?
Ans) Never. It is much too radical and extensive a change to be
MFC'ed. Besides, it needs many months of experience and
tuning before it is ready for widespread use.
6) What happens if a background fsck fails (i.e., fsck finds
errors that would normally require a manual fsck)?
Ans) The filesystem will be marked as needing a manual fsck.
At the next system reboot, the check will be done in
foreground and the usual actions taken (usually a failure
to go multi-user until fsck has been run by hand on the
affected filesystem).
the null mount, we currently create a temporary mfs on /tmp, copy
/etc to /tmp, then mount /etc as mfs and copy everything back from
/tmp, then delete the /tmp mfs.
The patch eliminates the temporary /tmp mfs and the subsequent
copying and simply populates the /etc mfs by copying from
/conf/default/etc. This requires that /conf/default/etc contain a
complete copy of all the /etc stuff instead of just overrides. I
don't think that is too much of an extra step in setting up a
diskless environment.
* Provide the ability to make /tmp a memory filesystem independent
of /var. This removes the requirement that /tmp be a symlink to
/var/tmp and this makes the diskless code work with the default
filesystem layout. If a seperate /tmp memory filesystem is
created, the 'tmpsize' environment variable is used to determine
its size (default to 10 Meg).
* Reduce diffs between the -current and -stable versions of these
files to a bare minimum. Only the definition of the shell
function 'mount_md' is different.

This driver supports PCI Xr-based and ISA Xem Digiboard cards.
dgm will go away soon if there are no problems reported. For now,
configuring dgm into your kernel warns that you should be using
digi. This driver is probably close to supporting Xi, Xe and Xeve
cards, but I wouldn't expect them to work properly (hardware
donations welcome).
The digi_* pseudo-drivers are not drivers themselves but contain
the BIOS and FEP/OS binaries for various digiboard cards and are
auto-loaded and auto-unloaded by the digi driver at initialisation
time. They *may* be configured into the kernel, but waste a lot
of space if they are. They're intended to be left as modules.
The digictl program is (mainly) used to re-initialise cards that
have external port modules attached such as the PC/Xem.

BSDPAN is the collection of modules that provides tighter than ever

Currently, BSDPAN does the following:

o registers Perl modules in the FreeBSD package database with a

The name is of the form: bsdpan-ModuleName-V.VV.

Bring in required TLI library routines to support this.
Since we don't support TLI we've essentially copied what NetBSD
has done, adding a thin layer to emulate direct the TLI calls
into BSD socket calls.
This is mostly from Sun's tirpc release that was made in 1994,
however some fixes were backported from the 1999 release (supposedly
only made available after this porting effort was underway).
The submitter has agreed to continue on and bring us up to the
1999 release.
Several key features are introduced with this update:
Client calls are thread safe. (1999 code has server side thread
safe)
Updated, a more modern interface.
Many userland updates were done to bring the code up to par with
the recent RPC API.
There is an update to the pthreads library, a function
pthread_main_np() was added to emulate a function of Sun's threads
library.
While we're at it, bring in NetBSD's lockd, it's been far too
long of a wait.
New rpcbind(8) replaces portmap(8) (supporting communication over
an authenticated Unix-domain socket, and by default only allowing
set and unset requests over that channel). It's much more secure
than the old portmapper.
Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
to support TI-RPC and to support IPV6.
Umount(8) is also fixed to unmount pathnames longer than 80 chars,
which are currently truncated by the Kernel statfs structure.
