SOMAXCONN (kern.somaxconn), SOMINCONN (kern.sominconn), and TCPTV_KEEP_INIT (net.inet.tcp.keepinittime). when this is not enough (ie. overfull), start doing tail drop, but slightly prefer the same port.
1996-09-12Close TCP receive window when we cannot receive data; suggested by DarrenThorsten Lockert
Reed. Also make a conditional easier to read.

1996-07-29Fix a small bug and change the logic of the bind() port choosing:Jason Downs
Use a random starting point the first time through the loop.
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."

1996-05-22When sending an ARP request, use the interface address for the route, ratherTheo de Raadt
than the first address assigned. This gives slightly different behaviour in the presence of aliases. From Bill Fenner, via Pete Bentley.
