Modified files:
sys/netinet in.h in_pcb.c
Log:
Change the default port range for outgoing connections by introducing
IPPORT_EPHEMERALFIRST and IPPORT_EPHEMERALLAST with values
10000 and 65535 respectively.
The rationale behind is that it makes the attacker's life more
difficult if he/she wants to guess the ephemeral port range and
also lowers the probability of a port colision (described in
draft-ietf-tsvwg-port-randomization-01.txt).
While there, remove code duplication in in_pcbbind_setup().
