where "/var/db/kvm_kernel.db" exists.
Note, kvm_mkdb tries to be clever, and skips rebuilding the database
if it thinks it's already up to date. To see the effects of this
fix, you may need to manually delete "/var/db/kvm_kernel.db" and
then run "kvm_mkdb".
match - otherwise, with a delayed (\\d) ``send'', the
timeout may happen during the send and cause a failure.

are done in the same way as command execution.
For example, ``set proctitle USER INTERFACE PROCESSID'' would
be useful in a -direct profile for identifying who's connected.
They checked for the magic major number for the "device" behind mfs
mount points. Use a more obvious check for this device.

for every machine on every class C or smaller subnet that we
route to.
Add ``set {send,recv}pipe'' for controlling our socket buffer
sizes.
Mention the IP number with the problem in a few error messages.

like
tun0: flags=blah
10.0.0.1 -> 10.0.0.100
10.0.0.2 -> 10.0.0.100
10.0.0.3 -> 10.0.0.100
to DTRT, despite the SIOCAIFADDR for each new alias returning
-1 & EEXIST while adding the alias anyway. In real life, once
we have the second alias with the same destination, nothing will
route any more ! Also, because I was ignoring EEXIST, the
dynamic IP assignment code was assigning duplicate addresses
('cos it was being lied to by iface_inAdd()).
Now we have
tun0: flags=blah
10.0.0.1 -> 255.255.255.255
10.0.0.2 -> 10.0.0.100
10.0.0.3 -> 255.255.255.255
This works - stuff bound to 10.1 & 10.3 will be considered alive
by the kernel, and when they route back to the tun device, the
packets get aliased to 10.2 and go out to 10.100 (as with the
original plan).
We still see the EEXIST in SIOCAIFADDR, but ignore it when our
destination is 255.255.255.255, assuming that the alias *was*
actually added.
Additionally, ``iface add'' may now optionally be given only
the interface address. The mask & destination default to
255.255.255.255.
clear if the check is necessary, but vfs_object_create() is called
for all vnodes and it was silly to create objects for VBLK vnodes
that don't even have a driver.
when bdevsw[] became sparse. We still depend on magic to avoid having to
check that (v_rdev) device numbers in vnodes are not NODEV.
Removed a redundant `major(dev) < nblkdev' test instead of updating it.
Don't follow a garbage bdevsw pointer for attempts to swap on empty
regular files. This case currently can't happen. Swapping on regular
files is ifdefed out in swapon() and isn't attempted for empty files
in nfs_mountroot().

- dev != NODEV was checked for, but 0 was returned on failure. This was
fixed in Lite2 (except the return code was still slightly wrong (ENODEV
instead of ENXIO)) but the changes were not merged. This case probably
doesn't actually occur under FreeBSD.
- major(dev) was not checked to have a valid non-NULL bdevsw entry. This
caused panics when the driver for the root device didn't exist.
Fixed minor misformattings in bdevvp(). Rev.1.14 consisted mainly of
gratuitous reformattings that seem to have caused many Lite2 merge
errors.
