d2fa5c91a7 Fix bug #21699: segment leak in ooseq processing when last data packet was lost (free last segment if FIN is already received) 2007-12-13 20:24:39 +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

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

1faf0ab9e3 Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into inet and chksum part; changed includes in all lwIP files as appropriate 2007-11-16 19:31:10 +00:00

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
goldsimon
853765954e Fixed bug #21181: On active open, the initial congestion window was calculated based on the configured TCP_MSS, not on the MSS option received with SYN+ACK. 2007-11-01 15:51:43 +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

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...):
