I need a clarification about the IPV6_PATHMTU ancillary data item
defined in draft-ietf-ipngwg-rfc2292bis-01.txt. The draft does not
(explicitly) mention how the application knows the corresponding
destination address for the returned MTU value. Which is correct?
1. this option has its meaning for a connected socket only. The
destination is the foreign address of the socket.
2. the destination address should be specified in the msg_name member
returned by the corresponding recvmsg() call.
3. the current spec is buggy. The ancillary data should contain the
socket address structure for the destination.
4. others
In any case, I think some text about this point should be added in the
next revision of the spec. Thanks,
