- Use MAP_FAILED instead of the constant -1 to indicate
failure (required by POSIX).
- Removed flag arguments of '0' (required by POSIX).
- Fixed code which expected an error return of 0.
- Fixed code which thought any address with the high bit set
was an error.
- Check for failure where no checks were present.

bogus path and FTP I/O errors much earlier, offer retry possibilities
at steps along the way so you don't have to resume from the very beginning
again on a hard error.
1. Bus mouse selection didn't show up properly in mouse menu.
2. U&G management screen didn't respect cancel properly.
3. Novice not prompted to add users or set root password during installation.
4. Username length changes screw up user management form.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been

terminate(). This makes doubly sure we don't trip the SIGTERM handler
in a child process. Suggested by: phk.
- It's int main(argc, argv), not void main(argc, argv), gosh darn it.
- If a child receives a SIGTERM, it will call the terminate() function
and end up doing the shutdown procedurs that should really only be
done by the parent. Set the SIGTERM behavior back to SIG_DLT in the
child after fork()ing.
- If the parent fails to read data back from the child because the
child has exited, it will call rpc_received() with bogus tdata that
can cause the parent to SEGV. Make handle_children() detect this
condition correctly and handle it sanely.
*sigh* Another 2.2 candidate.
This has the effect of making every link a "passthrough" which means the
TCP or UDP port won't be freed after link deletion -- so there could be
eventual port exhaustion if the program were allowed to operate long
enough.

to be used to expand things beyond the size of the buffer passed in. Also
do a general cleanup of sprintf -> snprintf as well as strcpy and strncat
safety. Also expand some buffers to allow for the largest possible data
that might be used.
This is a 2.2 candidate. However, it needs to be vetted on -current
since little testing has been done on this due to my lack of PPP on
this machine.

is a little harsh, but it helps prevent the parent from blocking
and causing other requests to time out.
yp_dnslookup.c:
- Check for duplicate RPC transaction IDs that indicate duplicate
requests sent due to RPC retransmissions. We don't want to send
a second DNS request for the same data while an existing request
is in progress.
- Fix small formatting bogon in snprintf() in yp_async_lookup_addr().
Use consistent spelling throughout.
Remove unmount in fixit_common() since that's bogus in the CDROM case and
properly "shut down" the media device instead.
- Try to have all output go through the routines in util.c [logerr(),
log_1s(), die()]
- Add *some* code in util.c to allow pccardd to run out of sysinstall.

- yp_main.c: Always add the resolver socket to the set of fds
monitored by select(). It can happen that pending == 0 but we
still have some data in the socket buffer from an old query.
This way, the data will be flushed in a timely manner.
- yp_extern.h: remove proto for yp_dns_pending() since we don't need
it anynmore.
- yp_server.c: call yp_async_lookup_name()/yp_async_lookup_addr()
functions with the svc_req pointer as an arg instead of the xprt.
(The svc_req struct includes a pointer to the transport handle,
and it also has the service version number which the async DNS
code will need. (see below))
- yp_dnslookup.c:
o Nuke yp_dns_pending() since we don't need it anymore.
o In yp_run_dnsq(), swallow up and ignore replies if no requests
are pending or the ID doesn't match any of the IDs in the queue.
o In yp_send_dns_reply(), we assume that we will always be
replying to an NIS v2 client. While this will probably always
be the case, we do support the v1 'match' procedure, and it
has a different result struct than v2. For completeness,
support replying to both NIS v1 and v2 clients.
o Update the queue entry structure to include a member to
keep track of the NIS version number.
o Have yp_async_lookup_name/addr() extract the version number
from the svc_req structure and save it with the queue entry
for yp_send_dns_reply() to inspect later.
o Add some comments.
- Don't dereference a NULL hostent pointer (if T_PTR lookup fails).
- Today I asked myself: "Self, you wrote this nifty async resolver
that does a great job handling delayed replies to clients using
the UDP transport, and the yplib code in libc always uses UDP
(except for yp_all()). But what if some dork makes a DNS lookup using
TCP?" Being the only dork on hand at the time, I tried it and was
enlightened. As I suspected, my transaction ID frobbing hacks cause
fireworks if called on a TCP transport handle (duh: the structures
are different). Fix: check the type of socket in xprt->xp_sock using
getsockopt() and don't use svcudp_get_xid() and svcudp_set_xid() for
anything except SOCK_DGRAM sockets. (Since accept() gives you a
new socket for each connection, the transaction ID munging isn't
needed for TCP anyway.)
