2008-05-24Remove {tcp/udp}6_usrreq(); Since the normal ones nowThordur I. Bjornsson
take a proc argument, theres no need for these, since they are just wrappers. OK claudio@
2008-05-23Deal with the situation when TCP nfs mounts timeout and processesThordur I. Bjornsson
get hung in nfs_reconnect() because they do not have the proper privilages to bind to a socket, by adding a struct proc * argument to sobind() (and the *_usrreq() routines, and finally in{6}_pcbbind) and do the sobind() with proc0 in nfs_connect. OK markus@, blambert@. "go ahead" deraadt@. Fixes an issue reported by bernd@ (Tested by bernd@). Fixes PR5135 too.

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
2005-03-04- check th_ack against snd_una/max; from Raja Mukerji via hugh@Markus Friedl

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!
