d9157a71bb Task #10088: Correctly implement close() vs. shutdown(). Now the application does not get any more recv callbacks after calling tcp_close(). Added tcp_shutdown(). 2010-02-20 18:05:56 +00:00

5d360a6711 Replaced struct ip_addr by typedef ip_addr_t to make changing the actual implementation behind the typedef easier. 2010-02-04 18:47:44 +00:00

5fa0347e64 Cleanly separate the portability file inet.h and its contents from the stack: moved htonX- functions to def.h (and the new def.c - they are not ipv4 dependent), let inet.h depend on ip_addr.h and not the other way round. This fixes bug #28732. 2010-01-29 08:20:32 +00:00

0644c4c08e Fixed bug #27871: Calling tcp_abort() in recv callback can lead to accessing unallocated memory. As a consequence, ERR_ABRT means the application has called tcp_abort()! 2010-01-27 17:22:06 +00:00
