dccp: support for passing MSG_TRUNC
DCCP is datagram-oriented but lacks UDP's support for MSG_TRUNC as defined in
recvmsg(2)/recv(2). Hence the following 'Hello world\0' receiver
len = recv(fd, buf, 10, MSG_PEEK | MSG_TRUNC);
wrongly (always) returns 10, while in UDP it returns 12 as expected.
This patch adds the missing MSG_TRUNC support to recvmsg().
