35d1c33e0a tcp_alloc: prevent increasing stats.err for MEMP_TCP_PCB when reusing time-wait pcb as suggested by Bill 4 months ago 2009-11-22 17:52:48 +00:00

6d22c38e59 tcp_recv_null: call tcp_recved() if p != NULL to keep the window correct 2009-11-22 16:16:55 +00:00
goldsimon
6bb7f987f2 Fixed bug #28049 (Keep Alive timeout frees pcb then uses it, sometimes causing crash error) by calling tcp_rst() instead of tcp_abort() in tcp_slowtmr() when retransmit timer expires. 2009-11-22 15:44:12 +00:00

8cc32bc29c 2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm) 
* tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling
    of silly window avoidance and prevent lwIP from shrinking the window)
 2007-12-20 14:51:35 +00:00

8d3d08e814 fix bug #21699 (segment leak in ooseq): add assert that all segment lists are empty in tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED state from LAST_ACK in tcp_process 2007-12-04 20:41:12 +00:00
goldsimon
5743b11925 Check state == CLOSED in tcp_bind and tcp_connect to prevent binding/connecting twice (using LWIP_ERROR: can be disabled) 2007-11-25 18:37:34 +00:00
goldsimon
95425552d7 Implemented calculating the effective send-mss based on the MTU of the netif used to send. Enabled by default. Disable by setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21535. 2007-11-21 18:37:23 +00:00
goldsimon
2d5908f4de Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or TCP_MSS if that is smaller) as long as no MSS option is received from the remote host. 2007-11-01 16:53:43 +00:00
goldsimon
298d5cf042 Fixed bug #21491: The MSS option sent (with SYN) is now based on TCP_MSS instead of pcb->mss (on passive open now effectively sending our configured TCP_MSS instead of the one received). 2007-11-01 16:23:32 +00:00

7a99d73092 Added some explaining comments. 2007-10-28 17:43:21 +00:00

199648ff37 Changed initialization: many init functions are not needed any more since we now rely on the compiler initializing global and static variables to zero! 2007-10-09 19:59:56 +00:00
goldsimon
0aa3d89134 Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state) by checking tcp_tw_pcbs also 2007-09-20 18:27:50 +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

9152d6671c Comments Fix for Doxygen documentation 2007-08-09 22:21:44 +00:00
goldsimon
33054a18db Added a better comment to explain why tcp_close doesn't care for the return value of tcp_output 2007-07-26 09:31:09 +00:00
goldsimon
f4036e8352 Another fix for bug #20021: by not returning an error if tcp_output fails in tcp_close, the code in do_close_internal gets simpler (tcp_output is called again later from tcp timers). 2007-07-25 19:24:27 +00:00
goldsimon
62c3de30b9 Fix bug #20480: Check the pcb passed to tcp_listen() for the correct state (must be CLOSED). 2007-07-24 07:41:55 +00:00

fa4b711495 Added some ASSERTS and casts to prevent warnings when assigning to smaller types. 2007-07-02 20:13:45 +00:00
goldsimon
d228ff0f43 Removed warning when assigning from u32_t to u16_t by casting to u16_t. 2007-07-01 16:04:35 +00:00

6784fd64f3 Done some work on task #6933: converted some LWIP_ASSERTs to LWIP_ERROR to give back an error return value for LWIP_NOASSERT=1 2007-06-17 15:20:21 +00:00

c43ab76bbe Use TCP_RMV instead of tcp_pcb_remove when removing pcbs from tcp_bound_pcbs list (bug introduced while fixing bug #1895) 2007-05-29 11:02:53 +00:00
goldsimon
0aaf69769f Fixed bug #1895 (tcp_bind not correct) by introducing a list of bound but unconnected (and non-listening) tcp_pcbs. 2007-05-22 20:48:36 +00:00
goldsimon
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

79be888b6f * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission

7932bf483b Ongoing fix to patch #5822: converted more statements like (void)arg; into LWIP_UNUSED_ARG(arg); 2007-04-11 19:39:24 +00:00

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...):
