6865806b55 Combined IPv4 and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP code so that the code is more readable. 2011-05-25 17:16:35 +00:00

4bfbe7ebeb ... and finally, we got a first working version of a dual-stack lwIP runnin IPv4 and IPv6 in parallel - big thanks to Ivan Delamer! (this is work in progress, so please beware, test a lot and report problems!) 2011-05-17 19:35:14 +00:00

4495516497 Removed 'dataptr' from 'struct tcp_seg' and calculate it in tcp_zero_window_probe (the only place where it was used). 2011-03-27 12:56:16 +00:00

effcb90fdf Mreged back changes that were lost during the savannah hack 3 weeks ago (using the sources from http://git.infradead.org/users/dwmw2/lwip.git) 2010-12-20 18:03:51 +00:00

f7479781c1 bug #27352: removed packing from ip_addr_t, the packed version is now only used in protocol headers. Added global storage for current src/dest IP address while in input functions. 2010-05-22 21:11:02 +00:00

6ffd29507c Free recv_data when TF_RXCLOSED is set 2010-05-16 13:12:15 +00:00
goldsimon
a880709776 Let FIN come through although TF_RXCLOSED is set, send RST when data is received although TF_RXCLOSED is set, added TCP_EVENT_CLOSED for clearer code 2010-05-15 18:12:37 +00:00

a945bf07af SO_REUSE: tcp_input: correctly handle multiple pcbs listening on the same port (but different address): first search for a specific address an only pass to ANY if no specific address has been found listening 2010-05-15 16:45:43 +00:00

ef0a7ecbcd Remove uused SOF_* flags, define inherited flags in ip.h, not in tcp_in.c 2010-05-12 22:26:06 +00:00

cf0b831971 Fixed bug #29080: Correctly handle remote side overrunning our rcv_wnd in ooseq case. 2010-03-25 06:39:01 +00:00

b6542b977e task #7040 (Work on tcp_enqueue): Don't waste memory when chaining segments, added option TCP_OVERSIZE to prevent creating many small pbufs when calling tcp_write with many small blocks of data. Instead, pbufs are allocated larger than needed and the space is used for later calls to tcp_write. 2010-03-05 11:14:31 +00:00

bcd4b76d31 Moved stack-internal parts of tcp.h to tcp_impl.h, tcp.h now only contains the actual application programmer's API 2010-02-21 11:35:21 +00:00
goldsimon
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
