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

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

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

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...):
