ToDo:							-*- text -*-

----------------------------------------------------------------------
Memory allocation locality:

Currently mallocs memory in a very haphazard manner.  As such, most of
the program ends up core-resident all the time just to follow all the
stupid pointers around. . . .

----------------------------------------------------------------------
Input parser:

The reader implemented in readfile.c could use improvement.  Some sort
of "data-driven" parser should be used so the big switch statements
would have only one case for each data type instead of one case for
every recognized option symbol.  Then adding a new tag would involve
only adding a new element to the data table describing known symbols.
Hopefully, this would shrink the code a bit too. -gwr

----------------------------------------------------------------------
SLIP Initialization via BOOTP:

In the function handle_request(), both in bootpd and bootpgw,
we might want to add code like the following just before testing
the client IP address field for zero. (bp->bp_ciaddr == 0)
(David suggests we leave this out for now. -gwr)

#if 1	/* XXX - Experimental */
	/*
	 * SLIP initialization support.
	 *
	 * If this packet came from a SLIP driver that does
	 * automatic IP address initialization, then the socket
	 * will have the IP address and the packet will
	 * have zeros for both the IP and HW addresses.
	 *
	 * Thanks to David P. Maynard <dpm@depend.com>
	 * for explaining how this works. -gwr
	 */
	if ((bp->bp_ciaddr.s_addr == 0) &&
		(bp->bp_htype == 0))
	{
		/* Pretend the client knows its address.  It will soon. */
		bp->bp_ciaddr = recv_addr.sin_addr;
		if (debug)
			report(LOG_INFO, "fixed blank request from IP addr %s",
				   inet_ntoa(recv_addr.sin_addr));
	}
#endif

DHCP Support:

There is a set of patches from Jeanette Pauline Middelink
<middelin@calvin.polyware.iaf.nl> to add DHCP support.

Those patches will be integrated into the BOOTP release stream
very soon, but if you can't wait, you can get them from:
nimbus.anu.edu.au:/pub/tridge/samba/contributed/DHCP.patch
