@ -35,157 +35,6 @@ o Added a check for socklen_t in configure.in and used socklen_t when
calling getsockname and getsockopt to avoid a "pointer targets differ
in signedness" warning on platforms where socklen_t is unsigned.
o Made some code changes to intf.c (the patch below). This does the following:
o Preserve the alias qualifier from interface name in more cases
(e.g. don't blow away :2 from eth0:2 when it may still be needed.
o Set the SO_BROADCAST flag on the interface list descriptor so that
broadcast/network IPs can be investigated.
o Update _match_intf_src so that it checks interface aliases for the
given source address rather than only the main interface address.
