f9ce31f98b TCP: Implement dual stack support using new IP_ANY_TYPE introduced at UDP 2016-03-02 23:14:33 +01:00
Joel Cunningham
8cb64698aa Allow backlog to be updated 
This commit adds support to the sockets and netconn layer to update the
backlog by calling listen when the netconn is already in the listen state.
When backlog is not enabled, the call returns successfully

This commit also introduces a macro for setting the backlog value that
prevents a 0 sized (invalid) backlog

953b7bdd59 Implement UDP dual-stack PCB support 
Create special IP address type "IPADDR_TYPE_ANY" for it.
SNMP uses new feature in non-netconn mode.

TODO: Same for TCP & RAW, adapt NETCONN to use this feature

c805843e64 Change signature of ip_output, ip_output_if, ip_output_if_src, ip_output_hinted, ip_route, ip_netif_get_local_ip, ip_route_get_local_ip and tcp_eff_send_mss not to take an isipv6 parameter. Use the IP version of the destination address instead. 2016-02-22 13:38:40 +01:00

880f1008d6 Together with Simon: Eliminate last instances of isipv6 member in pcbs; 
Don't allow NULL pointers (IPv4 ANY) in connect() and sendto() functions as destinations since this does not make sense.

5809b01388 Reduce usage of PCB IP version flag in raw and tcp code. Maybe we can figure out a good way for dual-stack UDP when we manage to remove the flag (nearly) entirely from the code. 2016-02-20 20:40:04 +01:00

5056d375f2 tcp_bind/tcp_connect: Omit checking for the same port if no port specified 
No port specified means to use a random port.
tcp_new_port() returns a new (free) local TCP port number on success.
So in this case we don't need iterating all lists to test if the port
number is used, tcp_new_port() alreay ensures the port is not used.

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
test/*

no modifications were done on ip6_addr_t.
