6b405eccd0 Tried to fix bug #47270 by accepting all ipv4 multicast packets (at IP level) when LWIP_IGMP is disabled 2016-03-04 21:57:47 +01:00

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.

7856141fc4 icmp: fix checksum on replies of echo request with ID 0, sequence 0 and either no data or any amount of 0x00 Bytes as data (closes: #45322) 
When a client sends an ICMP echo request with ID 0, sequence 0 and
either no data or any amount of 0x00 bytes as data, the checksum in the
reply is wrong (off-by-one).

Expected checksum is 0xffff in that case, observed is 0x0000.

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

no modifications were done on ip6_addr_t.
