f29bdd21a7 fixed bug #34426: tcp_zero_window_probe() transmits incorrect byte value when pcb->unacked != NULL 2011-10-09 20:11:33 +02:00

5c68bbe16f Tried to fix bug #32417 ("TCP_OVERSIZE seems to have problems with (fast-)retransmission"): Reset pcb->unsent_oversize in 2 more places... 2011-09-29 21:12:34 +02:00

dccad08508 use pcb->mss instead of TCP_MSS for preallocate mss-sized pbufs (bug #34019) 2011-09-11 13:13:26 +02:00

ed0626afeb fixed bug #33962 TF_FIN not always set after FIN is sent. (This merely prevents nagle from not transmitting fast after closing.) 2011-08-22 18:52:27 +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

3bad9f013e Fixed bug #32820 (Outgoing TCP connections created before route is present never times out) by starting retransmission timer before checking route. 2011-03-27 13:00:54 +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

f83ace2034 task #6849: Calculate checksum when creating TCP segments, not when (re-)transmitting them. 2010-03-14 11:26:05 +00:00

d13ac66cc4 Fixed sending one byte of data in tcp_zero_window_probe (which I accidentally broke with v1.103) 2010-03-14 09:43:10 +00:00

ad4a869b94 Some fixes to the TCP_OVERSIZE code:
- fix compiling with TCP_OVERSIZE==0;
- fix segment-size calculation when options are used;

097e8c8eb4 Fixed some issues in the TCP_OVERSIZE code:
- reset tcp_pcb.unsent_oversize when last_unsent is changed;
- added TCP_OVERSIZE_DBGCHECK: check tcp_pcb.unsent_oversize vs. (debug-only) tcp_seg.oversize_left to ensure the pcb counter is correct;
- fixed a memory leak in tcp_write;

92beddd72f task #7013 (Create option to have all packets delivered to netif->output in one piece): Always copy to try to create single pbufs in tcp_write. 2010-03-06 11:55:00 +00:00
goldsimon
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

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

a23b446ddf Use macros defined in ip_addr.h (some of them new) to work with IP addresses (preparation for bug #27352 - Change ip_addr from struct to typedef (u32_t) - and better code). 2010-02-04 17:21:32 +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

478ccee5fc tcp_rexmit(): no need to call tcp_output, since always called from tcp_input and thus tcp_output always returns without sending (prevent confusion by thinking data was sent while in tcp_rexmit!) 2009-11-26 16:44:16 +00:00
