-Subject: [PATCH] net: add validation for the socket syscall protocol argument
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-郭永刚 reported that one could simply crash the kernel as root by
-using a simple program:
-
-	int socket_fd;
-	struct sockaddr_in addr;
-	addr.sin_port = 0;
-	addr.sin_addr.s_addr = INADDR_ANY;
-	addr.sin_family = 10;
-
-	socket_fd = socket(10,3,0x40000000);
-	connect(socket_fd , &addr,16);
-
-AF_INET, AF_INET6 sockets actually only support 8-bit protocol
-identifiers. inet_sock's skc_protocol field thus is sized accordingly,
-thus larger protocol identifiers simply cut off the higher bits and
-store a zero in the protocol fields.
-
-This could lead to e.g. NULL function pointer because as a result of
-the cut off inet_num is zero and we call down to inet_autobind, which
-is NULL for raw sockets.
-
-kernel: Call Trace:
-kernel:  [<ffffffff816db90e>] ? inet_autobind+0x2e/0x70
-kernel:  [<ffffffff816db9a4>] inet_dgram_connect+0x54/0x80
