32f6e7e231 tcp: Fix ooseq processing when seqno is near 2^32
An edge case in out-of-sequence TCP packet processing did not use the
appropriate macro to check if the sender overran the recieve window.

Consequently, this case sometimes evaluated to true when it shouldn't, which
resulted in various bad behavior, including trying to resize a TCP buffer to 4
gigabytes.

0fb07ba328 - moved processing of refused_data to an own function (used from tcp_fasttmr and tcp_input);
- improved readability of tcp_slowtmr by using defines to access keepalive variables

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.

5fa0347e64 Cleanly separate the portability file inet.h and its contents from the stack: moved htonX- functions to def.h (and the new def.c - they are not ipv4 dependent), let inet.h depend on ip_addr.h and not the other way round. This fixes bug #28732. 2010-01-29 08:20:32 +00:00
