7466474365 Fixed compiler warnings when casting where we know the source is aligned (by casting to void-pointer first) 2010-03-15 10:44:19 +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

261dfdf010 fixed bug #24212: "Deadlocked tcp_retransmit due to exceeded pcb->cwnd": Fixed by sorting the unsent and unacked queues (segments are inserted at the right place in tcp_output and tcp_rexmit) 2009-04-26 12:27:11 +00:00

* tcp_out.c: BUG20511.  Modify persist timer to start when we are
    prevented from sending by a small send window, not just a zero

dc515c7ad3 Fixed bug #20287: tcp_output_nagle sends too early. This fixes the nagle algorithm; nagle now also works for all raw API applications and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY' 2007-11-21 17:59:03 +00:00

cbe9b050a9 sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c: Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api layer. This option enable to delayed TCP PUSH flag on multiple "write" calls. Note that previous "copy" parameter for "write" APIs is now called "apiflags". 2007-11-01 17:37:50 +00:00

e3cd1ac1f9 Minor changes (but in lot of files): add #if/#endif for options where they could miss. #if LWIP_xxx if always put after #include "lwip/opt.h" (note this one indirectly include cc.h). Move others includes inside #if/#endif block. 2007-09-07 23:01:59 +00:00

eb875de67e Added assertions where PBUF_RAM pbufs are used and an assumption is made that this pbuf is in one piece (i.e. not chained). These assumptions clash with the possibility of converting to fully pool-based pbuf implementations, where PBUF_RAM pbufs might be chained. 2007-07-03 20:28:35 +00:00

96e4ec4a15 Added option LWIP_NETIF_HWADDRHINT (default=off) to cache ARP table indices with each pcb instead of single-entry cache for the complete stack. 2007-07-02 20:41:22 +00:00
