  > Fix SysV message queue identifiers.
  > Found and diagnosed by Alexis Fouilhe hyjial at gmail dot com

net

  ~ pf.c                                  

  > Improve the ICMPv6 direction check
  > Following bluhm's advice this changes the way we setup state keys and
  > perform state lookups for ICMPv6 Neighbor Discovery packets:
  > - replace the NS-dst with ND target address;
  > - replace the NA-src with ND target address;
  > - replace the NA-dst with unspecified address if it is a multicast.
  > This allows pf to match Address Resolution, Neighbor Unreachability
  > Detection and Duplicate Address Detection packets to the corresponding
  > states without the need to create new ones or match unrelated ones.
  > As a side effect we're doing now one state table lookup for ND packets
  > instead of two.
  > Fixes a bug uncovered by one of the previous commits that virtually
  > breaks IPv6 connectivity after few minutes of use.
  > ok stsp henning, with and ok bluhm (mikeb@)

  > Do not insert an empty ENTRY into the manpath list;

  > While here, remove two unused local variables and two unused struct
  > members.
