0fb07ba328 - moved processing of refused_data to an own function (used from tcp_fasttmr and tcp_input);
- improved readability of tcp_slowtmr by using defines to access keepalive variables

0333e81616 fixed bug #34517 (persist timer is started although no zero window is received) by starting the persist timer when a zero window is received, not when we have more data queued for sending than fits into the window 2011-10-13 21:18:16 +02:00

07c610e068 Implemented limiting data on ooseq queue (task #9989) (define TCP_OOSEQ_MAX_BYTES / TCP_OOSEQ_MAX_PBUFS in lwipopts.h), added unit test for this new feature 2011-09-27 22:42:46 +02:00

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

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

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

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

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

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
