7e9377a9c7 dhcp: Use LWIP_ARRAYSIZE to get the number of array entries 
dhcp_discover_request_options is u8_t array, so the result is the same.
But use LWIP_ARRAYSIZE to get the number of array entries is better
because it works for all types.

6aed6e659f Rework DHCP PCB handling: Old code registered one UDP PCB per netif where DHCP was active and there was a special case in udp_input() for this. New implementation uses one PCB for all netifs and removes special case in udp_input(). 
The old approach called udp_bind() on each of the PCBs, which puts them into udp_pcbs list. The PCBs were iterated on all non-DHCP udp_inputs() with no effect.
My cleanup removes the special handling in udp.c, and uses only one DHCP UDP PCB to catch all DHCP messages from all netifs. The dhcp_recv function then checks whether ip_current_input_netif() has DHCP enabled - if not, the message is ignored. The PCB is only created/registered when one or more PCBs have DHCP enabled.

ba71ac78d9 Add functions to join/leave IGMP group by netif 
Existing functions are based on IP address, but the address is used
only to look up which netif to act on. The netif-based core code is
extracted to new exported functions.

If you have a netif handle, this makes it easier to join/leave
groups, without the need to convert to IP address first only for the
IGMP code to convert back to netif.

9f065c0ea5 (api break) qualify ip_addr_t as const where feasible 
this changes the callback signatures of the ip_output and the
{udp,raw}_recv functions.

changes were made by going through all header files, searching for
occurrences of ip_addr_t, qualifying them as const and if required
modifying the corresponding c files, looking for other uses of ip_addr_t
that would be required.

the following header files were not treated as i'm not using them and
wouldn't see them compiled: api.h api_msg.h dhcp.h dns.h igmp.h
netifapi.h pppapi.h snmp.h snmp_msg.h snmp_structs.h ppp.h pppol2tp.h

22e2540eb6 autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets in autoip". The change in etharp_raw could be removed, since all calls to etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be wrong in the future. 2007-12-31 13:22:03 +00:00

f3f7bd00e5 ip_input: check if a packet is for inp first before checking all other netifs on netif_list (speeds up packet receiving in most cases) 2007-12-03 17:55:01 +00:00

6d9b44e243 IP_REASSEMBLY: send ICMP time exceeded when discarding datagrams for which the first fragment was received; try to keep the header of the first (octet 0) fragment; combined code to make it smaller; fixed bug in timer: when freeing packets, counter was not updated correctly 2007-10-15 19:33:16 +00:00

1f08a5e5f5 Added code to free the oldest packets if the IP_REASS_MAX_PBUFS limit is reached or MEMP_REASSDATA is empty. 2007-10-11 19:49:06 +00:00

199648ff37 Changed initialization: many init functions are not needed any more since we now rely on the compiler initializing global and static variables to zero! 2007-10-09 19:59:56 +00:00

0f9799d7e0 Added todo: free the oldest entry when the MEMP_REASSDATA pool is empty or the IP_REASS_MAX_PBUFS limit is reached 2007-10-09 19:31:54 +00:00

8980c3f74e Typo in chain_frag_into_packet_and_validate (but obviously worked anyway...) 2007-10-09 06:13:12 +00:00

e561c7b49d Added check for overlapping or duplicate fragments. ip_reass_init() is not needed any more (the check is done in chain_frag_into_packet_and_validate()). 2007-10-07 11:52:32 +00:00

b7ef6077df Changed IP_REASSEMBLY to enqueue the received pbufs so that multiple packets can be reassembled simultaneously and no static reassembly buffer is needed. 2007-10-06 15:24:43 +00:00
