542b8fffb1 Fixed bug #25094: "Zero-length pbuf" (options are now allocated in the header pbuf, not the data pbuf); added function comments; "inline" is not supported by ANSI C (tcp_build_timetamp_option) 2009-04-19 12:31:16 +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
    send window.

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

8020ba2dc5 tcp_send_ctrl(): call tcp_enqueue with the new flag TCP_WRITE_FLAG_COPY instead of 1 2007-11-12 19:38:25 +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

8be76ed450 tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs: changed snd_queuelen++ to snd_queuelen += pbuf_clen(p). 2007-07-25 08:46:41 +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

255d5a748f Included patch #5920: Create define to override C-library memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for situations where some compilers might inline the copy and save a function call. Also replaced all calls to memcpy() with calls to (S)MEMCPY(). 2007-05-10 05:20:05 +00:00

5368a760cf most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with others environment defines (these were too "generic"). 2007-03-30 08:47:04 +00:00

7294cb080b * Fix all uses of pbuf_header to check the return value. In some
cases just assert if it fails as I'm not sure how to fix them, but
    this is no worse than before when they would carry on regardless
    of the failure.

5c65d4733b Keepalive values can be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this unless you know what you're doing (default are RFC1122 compliant). Note that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.
Old TCP_KEEPALIVE can always be used, and its only difference with TCP_KEEPIDLE is this last use seconds and not milliseconds with setsockopt.

Some documentation (not perfect, but...):
