MGET* macros were changed to function calls, there wasn't any need for the pool declarations and the inclusion of pool.h From: tbert <bret.lambert@gmail.com>
2007-06-25merge tcp_set_iss() and tcp_set_tsm(); ok mcbride, djm (on earlier version)Markus Friedl
2007-06-15Drop the current random timestamps and the current ISN generationMarkus Friedl
code and replace both with a RFC1948 based method, so TCP clients now have monotonic ISN/timestamps. The server side uses completely random ISN/timestamps and does time-wait recycling (on port reuse). ok djm@, mcbride@; thanks to lots of testers

- limit pool to tcp_sackhole_limit entries (sysctl-able) - stop sack option processing on pool_get errors - use SEQ_MIN/SEQ_MAX ok henning, hshoexer, deraadt

2003-12-08Mbuf tag tcp and udp packets which are translated to localhost, andRyan Thomas McBride
use the the presence of this tag to reverse the match order in in{6}_pcblookup_listen(). Some daemons (such as portmap) do a double bind, binding to both * and localhost in order to differentiate local from non-local connections, and potentially granting more privilege to local ones. This change ensures that redirected connections to localhost do not appear local to such a daemon. Bulk of changes from dhartmei@, some changes markus@ ok dhartmei@ deraadt@
2003-11-04add in(6)_pcblookup_listen() and replace all calls to in_pcblookup()Markus Friedl
with either in(6)_pcbhashlookup() or in(6)_pcblookup_listen(); in_pcblookup is now only used by bind(2); speeds up pcb lookup for listening sockets; from Claudio Jeker

2002-08-08socket buf speedup from thorpej@netbsd, okay art@ ericj@:Niels Provos
Make insertion of data into socket buffers O(C): * Keep pointers to the first and last mbufs of the last record in the socket buffer. * Use the sb_lastrecord pointer in the sbappend*() family of functions to avoid traversing the packet chain to find the last record. * Add a new sbappend_stream() function for stream protocols which guarantee that there will never be more than one record in the socket buffer. This function uses the sb_mbtail pointer to perform the data insertion. Make TCP use sbappend_stream(). On a profiling run, this makes sbappend of a TCP transmission using a 1M socket buffer go from 50% of the time to .02% of the time. Thanks to Bill Sommerfeld and YAMAMOTO Takashi for their debugging assistance!

inconsistency in corner cases (from NRL I believe). todd (fries) and I have seen panic, with the following call chain: ip6_input -> tcp_input -> tcp_respond -> ip_input -> bang! more cleanups should be done, to decrease complexity. for example, INP_IPV6_MAPPED should be nuked.
