Revision c71d8ebe7a4496fb7231151cb70a6baa0cb56f9a authored by Tetsuo Handa on 04 August 2011, 14:07:40 UTC, committed by David S. Miller on 05 August 2011, 10:31:03 UTC
The sendmmsg() introduced by commit 228e548e "net: Add sendmmsg socket system call" is capable of sending to multiple different destination addresses. SMACK is using destination's address for checking sendmsg() permission. However, security_socket_sendmsg() is called for only once even if multiple different destination addresses are passed to sendmmsg(). Therefore, we need to call security_socket_sendmsg() for each destination address rather than only the first destination address. Since calling security_socket_sendmsg() every time when only single destination address was passed to sendmmsg() is a waste of time, omit calling security_socket_sendmsg() unless destination address of previous datagram and that of current datagram differs.
