2004-05-07Replace RSA-derived md5 code with code derived from Colin Plumb's PD version.Todd C. Miller
This moves md5.c out of libkern and into sys/crypto where it belongs (as requested by markus@). Note that md5.c is still mandatory (dev/rnd.c uses it). Verified with IPsec + hmac-md5 and tcp md5sig. OK henning@ and hshoexer@
2004-05-04The tcp specific routing metrics are almost never used so reduce the routingClaudio Jeker
table from these metrics. struct rt_msghdr used by the routing socket is not affected and so most userland apps don't need to be changed. some man page polishing by jmc@ OK henning@ markus@ theo@
2004-04-26- allow the user to force the TCP mss below the fail-safe 216 with a lowMike Frantzen
interface MTU. - break a tcp_output() -> tcp_mtudisc() -> tcp_output() infinite recursion when the TCP mss ends up larger than the interface MTU (when the if_mtu is smaller than the tcp header). connections will still stall feedback from itojun@, claudio@ and provos and testing from beck@

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
