Normally trewind() performs a close-open-close cycle to rewind the
tape when closing the device, but this is not ideal for fifos. We
now skip the final open-close if the output descriptor is a fifo.

time_to_xxx() and xxx_to_time() functions. e.g. _time_to_xxx()

stopgap functions & placemarkers and not meant to create a defacto
standard. They will eventually be replaced when a real standard

are sometimes incorrectly being dumped.
The problem arises because the subdirectory only gets its entry
cleared from usedinomap if it is also present in dumpinomap, and it is
the absence of a directory in usedinomap that internally indicates
that the directory is under the effects of UF_NODUMP (either directly
or inherited).

with "DUMP: bad sblock magic number" when dump tried to parse
the directory contents as an FFS filesystem.

If one is trying to dump or repair an ill system, give the user a fighting
chance. Refusing to operate w/o a very non-critical file (feature) is
just plain stupid.
in cases where the supplied name was already pointing to a character
special device. This fixes the breakage that occured when trying to
dump a filesystem by name (e. g. /usr), with an fstab already
mentioning the raw device name (like /dev/rda0g) where dump attempted
to use /dev/rrda0g then.
Also removed the now obsolete remark that fstab were carrying block
special names.
so that dumps are treated by dump -w as having been done on midnight
of the day they were actually run. This makes dump -w behave as
expected for regularly scheduled daily dumps - if they all run the
same day. It makes dump -w behave strangely if you dump late in the
day and check again after midnight, but that is the lesser of two
evils.

<= 64 KB. Was able to dump/restore with block sizes of 96, 128 and
200. using systat -vmstat I noticed transfer blocksizes <= 64KB,
so physio's limits aren't touched.
Since this check was originally from me, I feels safe now to back it
out.
syndrome avoidance. The combination of SWS avoidance and ack-every-other
causes low throughput if the block size divided by the MSS is odd (which
is true with the default block size and MSS).
Turning on TCP_NODELAY disables the Nagle algorithm and sender SWS avoidance.
The rdump request/response protocol can not invoke Nagle and cannot cause
SWS, so this has no negative effects.
options one would normally expect to set the realm, enable encryption,

changes and one addition by me.
. Use reasonable defaults for the tape drive (/dev/rst0) instead of
something we actually don't have.
. Add a summary line displaying the alapsed time and the total throughput.
. Replace "rmt" for the remote location of rmt(8) by "/etc/rmt", since this
is the historical protocol, and relying on the $PATH causes a big pain.
Make it adjustable via an environmental variable though.

should be checking if the off_t is equal to -1 for failure.

an array. The bug became obvious in the old system where the array was only
32 characters long (now MAXPATHLEN). Dump honored its name then (:-)
and dumped its core when calling dump -w for a fstab that contained rather long
NFS file system names. Even though this is rather unlikely to happen now,
a bug is a bug:)
