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(). Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
