goldsimon
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;

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

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

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

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...):
