Show the IP range (if specified) in "show ipcp".
Close unused descriptors 0 and 2 in interactive mode.
Pass (size_t *) rather than (int *) to sysctl().
Don't read(fd, buffer, 0) and think ppp has closed the
connection when `buffer' is full, instead, flush most of
buffer to the terminal and read() for a reasonable length.
This fixes "show route" when there's more than 2k of
routing output.
used, and caused a reference to an uninitialised variable (state).
I think I've fixed it now, but since nothing in the tree seems to use it,
I'm not sure.
under -current. The actual preparation of the next track will now be
deferred until just before the first write operation. Otherwise,
opening the device with write intent will cause the execution of
commands that are illegal in `limited command set mode' (i.e., after
the write channel has been opened).
While i was at it, cleaned up the worm_open() function a bit.
Removed the volume overflow pre-check in worm_strategy(). It was
time-consuming, and rather useless in many cases anyway (with the size
being reported for just the entire volume only), so we can as well let
the actual SCSI command fail instead, where it'll properly be reported
as EIO.

fix PR#3618 weren't sufficient since malloc() can block - allowing the
net interrupts in and leading to the same problem mentioned in the
PR (a panic). The order of operations has been changed so that this
is no longer a problem.
Needs to be brought into the 2.2.x branch.

instead of Singe Unix, thanx Bruce for explaining, I am not realize
standards war was there.
But now, fix n == 0 case to not return error and fix check for too
big n.
Things left to do: check for overflow in arguments.
Final word is Bruce's quote:
C9x specifies the BSD4.4-Lite behaviour:
[#3] ... Thus, the
null-terminated output has been completely written if and
only if the returned value is less than n.
It means that if we not have any null-terminated output as for n == 0
we can't return value less than n, so we forced to return value
equal to n i.e. 0
The next good thing is glibc compatibility, of course.
2) Do check for too big n in machine-independent way.
3) Minor optimization assuming EOF is < 0
