d026a3954a Dual-stack fixes in raw/udp/tcp 
bind() may change IP type when previous type is IPADDR_TYPE_ANY
connect() IP type must exactly match bind IP type
Use correct IPADDRx_ANY type when calling ip_route()

13fb616bb2 Cleanup hton*/ntoh* function handling and platform abstraction 
Let lwip use functions/macros prefixed by lwip_ internally to avoid naming clashes with external #includes.
Remove over-complicated #define handling in def.h
Make functions easier to override in cc.h. The following is sufficient now (no more LWIP_PLATFORM_BYTESWAP):
#define lwip_htons(x) <your_htons>
#define lwip_htonl(x) <your_htonl>

633696c153 Implement consistent IPx_ADDR_ANYx macro naming between IPv4 and IPv6 
- rename IP4_ADDR_ANY to IP4_ADDR_ANY4
- IP4_ADDR_ANY (= IP_ADDR_ANY) is now IPv4 any address in ip_addr_t format

bf5866b27d tcp: Prevents a 0 sized (invalid) backlog 
commit 44e1a2d8e23f accidently includes below changes in tcp_listen_with_backlog
 -  tcp_backlog_set(lpcb, backlog);
 +  lpcb->backlog = backlog;

Thus pass 0 to the backlog parameter of netconn_listen_with_backlog() fails.

Fixes: 44e1a2d8e23f ("define tcp_backlog_set() as dummy-define when backlog feature is disable")

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

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.
