FreeBSD/src 3e14657 (r307726) — sys/netinet tcp_subr.c ip_icmp.c, sys/netinet6 ip6_input.c icmp6.c

by Michael Tuexen (tuexen) on ⎇
Make ICMPv6 hard error handling for TCP consistent with the ICMPv4
handling. Ensure that:
* Protocol unreachable errors are handled by indicating ECONNREFUSED
  to the TCP user for both IPv4 and IPv6. These were ignored for IPv6.
* Communication prohibited errors are handled by indicating ECONNREFUSED
  to the TCP user for both IPv4 and IPv6. These were ignored for IPv6.
* Hop Limited exceeded errors are handled by indicating EHOSTUNREACH
  to the TCP user for both IPv4 and IPv6.
  For IPv6 the TCP connected was dropped but errno wasn't set.
