fa661adb98 Do classing for BOOTP clients as well as DHCP clients. 1999-06-10 00:36:27 +00:00

431693d164 Prioritize user-declared parameter request list _above_ client-supplied list. 1999-05-07 17:40:26 +00:00
Ted Lemon
cdc336ab50 - In DHCPINFORM, allow for buggy clients that do not set ciaddr by 
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.
 1999-05-06 20:35:48 +00:00
Ted Lemon
46904800ec - Reference siaddr from state structure in ack_lease, since raw packet 
hasn't been instantiated yet.
 1999-04-23 23:47:51 +00:00
Ted Lemon
10553ccb84 - Do not respond with NAK if ciaddr is set and imputed network doesn't 
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.

e77892f581 Support DHCPINFORM. 1999-04-12 22:18:58 +00:00

cfb80b3cc0 Pool scope and subnet scope are different leaves of the same tree - 
handle them differently.
 1999-03-10 21:32:59 +00:00

eddb16f478 - Tack parameter request list on to lease state structure so that it will 
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.

8ae2d59584 Change names of error functions to be more consistent. 1999-02-24 17:56:53 +00:00
Ted Lemon
027f46cb67 - Pull up recent 2.0 changes. 
- 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.

b3f15965cc Classify all incoming dhcp packets. Process class scopes. 1998-11-06 02:59:11 +00:00
Ted Lemon
1ffcdd2a19 Don't test for abandoned lease if we didn't find a lease. Don't try to evaluate an option cache if we didn't find it. 1998-11-06 01:04:32 +00:00
Ted Lemon
8d44908072 Add agent option support. 1998-11-06 00:17:12 +00:00

c54885bd2d If a client REQUESTs an abandoned lease, reclaim it. 1998-06-25 21:24:23 +00:00
Ted Lemon
b1dd98c948 Move a lot of packet discard code into ack_lease(), after we've evaluated the statements associated with a packet. Use new-style option processing. No more explicit user/vendor class support. Revamp lease time processing. Get client identifier directly from host declaration. 1998-06-25 03:56:24 +00:00
Ted Lemon
5941275aac Do client classification. If user supplies a dhcp-lease-time or related option, print a warning when issuing a lease. 1998-04-19 23:34:43 +00:00
Ted Lemon
421563ea10 Don't respond to requests that are newer than a configured number of seconds. Enforce a minimum lease time, if specified. If a dhcp-server-identifier option has been specified, use that instead of coming up with one from the shared_network structure. Allow the routers option to be set to the client's address. Be more clever about dealing with duplicate leases. 1998-04-09 04:41:52 +00:00
Ted Lemon
48984237a1 If we happen across an abandoned lease when trying to find a lease to allocate, try using the abandoned lease. If the client asks for a lease on one address, but we find another lease that's also assigned to it, make every effort to free the duplicate lease, since a client can't have two leases on the same network at the same time. 1998-03-17 18:14:51 +00:00
Ted Lemon
f3c3d67454 Allow unnamed host declarations. 1998-03-17 06:20:51 +00:00

a7822eac77 Declare arguments that can be promoted so that the compiler's behaviour doesn't change depending on whether or not it follows ANSI. Fix signed vs. unsigned char discrepencies. 1998-03-16 06:19:46 +00:00
Ted Lemon
3c893bb6ce Adjust cons_options calls. Copy the entire chaddr field even if hlen indicates it's shorter. Keep track of Relay Agent Information options. 1998-02-06 01:08:38 +00:00
Ted Lemon
0c11afbceb NAK if a client requests an address that we own but can't give to it. 1997-12-06 04:04:50 +00:00
Ted Lemon
355bf452dc If we're responding to a BOOTP request, hunt for a lease that's applicable - there might be more than one lease matching the network and the hardware address. 1997-12-02 09:28:08 +00:00
Ted Lemon
ec8d21a783 Copy the hardware address into the static lease structure so that it can be used later. 1997-12-02 09:07:03 +00:00
Ted Lemon
599c23c128 If we find more than one lease for the same client on the same network, give it the one it asked for. 1997-12-02 07:43:56 +00:00
