1998-05-18first step to the setsockopt/getsockopt interface as described inNiels Provos
draft-mcdonald-simple-ipsec-api, kernel notifies (EMT_REQUESTSA) signal userland key management applications when security services are requested. this is only for outgoing connections at the moment, incoming packets are not yet checked against the selected socket policy.

1998-02-01undo wildcard loopback stuff; it was not checked by other developersTheo de Raadt
1998-02-01support wildcard loopbacks. that is, setting up lo1 like:Michael Shalayeff
ifconfig lo1 inet 192.168.1.1 netmask 255.255.255.0 link1 would force it to act like all the addresses from net 192.168.1 were added to the interface. todo: man lo
1997-08-09The list of tcp/udp ports not to allocate dynamically is nowTodd C. Miller
a bitmask configurable via sysctl([38]). The default values have not changed. If one wants to change the list it should be done early on in /etc/rc.

1996-08-02Allow viewing of net.inet.ip.sourceroute in secure modeThorsten Lockert
1996-07-29From FreeBSD (with slightly different sysctl names):Jason Downs
"... Allow the user to nominate one of three ranges of port numbers as candidates for selecting a local address to replace a zero port number. The ranges are selected via a setsockopt(s, IPPROTO_IP, IP_PORTRANGE, &arg) call. The three ranges are: default, high (to bypass firewalls) and low (to get a port below 1024). The default and high port ranges are sysctl settable under sysctl net.inet.ip.portrange.* [net.inet.ip.portfirst, net.inet.ip.portlast, net.inet.ip.porthifirst, and net.inet.ip.porthilast currently in OpenBSD.] This code also fixes a potential deadlock if the system accidently ran out of local port addresses. It'd drop into an infinite while loop. The secure port selection (for root) should reduce overheads and increase reliability of rlogin/rlogind/rsh/rshd if they are modified to take advantage of it."

1995-12-14re-add my source routing stuff (geeezzz)Theo de Raadt
1995-12-14from netbsd:Theo de Raadt
make netinet work on systems where pointers and longs are 64 bits (like the alpha). Biggest problem: IP headers were overlayed with structure which included pointers, and which therefore didn't overlay properly on 64-bit machines. Solution: instead of threading pointers through IP header overlays, add a "queue element" structure to do the threading, and point it at the ip headers.
