Log Message:
Pull up revision 1.72 via patch (requested by christos in ticket #961):
PR/27286: Tom Ivar Helbekkmo: Allow RTM_GET to work with RTA_IFA|RTA_IFP set.
Quiting Tom: The problem is the special case of an RTM_GET message
that wants interface information included in the response, and
therefore include the RTA_IFA or RTA_IFP (or both) flags in the
bitmask that says what addresses are supplied in the message.  For
the RTM_GET message, it doesn't make sense to supply addresses
other than the one you're asking about, so those two other bits
are, in that specific case, overloaded with this meaning.
There is code in sys/net/rtsock.c to handle the case, but at some
time, extra sanity checking of the received message was added, that
failed to take this possibility into account.
The patch, is needed for the Asterisk software PBX to work properly
when it has multiple interfaces active: it needs to ask the kernel
for the IP address of the interface that will be used to communicate
with a given host.
