15c24b882b Changed supersede_lease() to return 1, even if the commit option is 
not specified.  (Before, it would always return 0 if commit was not
given.)  Fixed up the one call to supersede_lease() which expected
the old behavior.

Added a check to supersede_lease() to return an error if the pimmediate
flag is given, and commit is not.  (You should never be sending information
on an uncommitted lease to a peer.)

Separated the failover queue update (the propogate flag) test from
the commit test in supersede_lease(), so that you can now enqueue an
update on an uncommitted lease.

b992d7e23d DDNS implementation rewrite. DDNS should now operate according to 
<draft-ietf-dhc-dhcp-dns-12.txt>.

common/options.c, common/tables.c, includes/dhcp.h:
  Split the fqdn.name option into fqdn.hostname and fqdn.domainname.

includes/dhcpd.h, server/Makefile.dist, server/ddns.c, server/dhcp.c,
server/mdb.c, server/stables.c:
  Added a new file (server/ddns.c) containing the DDNS updates code.
  This file exports two functions: ddns_updates() and ddns_removals().
  ddns_updates() is called when a lease is granted, and ddns_removals()
  is called when the lease expires or is released.

server/dhcpd.c:
  Remove the previous DDNS update code, and add default code for the
  ddns-hostname, ddns-domainname, ddns-ttl, and ddns-rev-domainname
  server options.

df73931267 More fixups for lease expiry code. 1999-11-14 00:32:28 +00:00
Ted Lemon
ccbdce1467 - Delete on_expiry events when lease is released, regardless of whether 
there's a release event.
- If the lease being superseded is the next in a pool to expire, clean that
  up before superseding.
- Also, if the next lease to expire in a pool expires at the same time as
  the current lease, make sure that both expire, not just one.
