using the IP source address from the IP header if ciaddr is zero.
- Fix some memory allocation botches.
- Use parameter request list option from scope if it is present and
client didn't send one.
- Copy ciaddr from incoming packet to outgoing packet.
- Remember that we got the requested-address and server-identifier
options in option state.
- Allow for RFC1541 clients that set ciaddr when REQUESTING by
checking server-identifier option as well as ciaddr before
unicasting.
match, since ciaddr means client is unicasting using IP routing.
- Support DHCPINFORM even on unknown networks.
- Fix up some invocations of evaluate_option_cache that used
post-scope-execution option state rather than packet option state as
input for evaluations of options from post-scope-execution option
state.
- Add support for site-defined option spaces.
- Compute boot file server prior to freeing options used in computing
it. May fix a core dump that has been reported but that I haven't
seen.
- Make pool scope less specific than class scope.
- Fix some invocations of execute_statements_in_scope that were
incorrectly passing output options where they should have passed
input options.
- Enforce maximum lease length after applying default lease time.
- Compute value of bootfile server IP address in ack_lease instead of
dhcp_reply, so that expressions using contents of packet can work.
still be available when we call cons_options.
- Pass parameter request list to cons_options where needed, and in any case
pass the extra argument.
- Free parameter request list before freeing lease state structures.
- Fix some problems in DHCPREQUEST code regarding client identity.
- Update references to lease's shared network to use subnet pointer.
- If there's more than one lease matching a particular hardware address,
examine them all for possible applicability in find_lease().
- Only recover abandoned leases on DHCPREQUEST if the request was for
the specific abandoned lease. Push all other abandoned lease
recovery code out into DHCPDISCOVER/allocate_lease processing.
