Modified files:
xorp/fea/: netlink_socket.cc netlink_socket.hh
Log message:
Implement properly the reading of a large or multipart netlink
message:
- When reading from a netlink socket, first use repetitive
recv(MSG_DONTWAIT | MSG_PEEK) to find the size of the message
in the socket (in case the original size estimation is wrong).
- When reading a netlink message from a socket, check the
NLM_F_MULTI flag in the netlink message header. If this
flag is set, then this is a multipart message that must
be terminated by a NLMSG_DONE message. Hence, read all
messages up to (and including) the NLMSG_DONE, and pass
them together to the observer(s).
