This code criples 2.2.7 and 2.2.8 but I haven't tested it on any 3.x stable kernels. Does anyone know if this has been fixed with 3.x kernels? The code is fairly old... #include <unistd.h> #include <sys/socket.h> #include <fcntl.h> #define BUFFERSIZE 204800 extern int main(void) { int p[2], i; char crap[BUFFERSIZE]; while (1) { if (socketpair(AF_UNIX, SOCK_STREAM, 0, p) == -1) break; i = BUFFERSIZE; setsockopt(p[0], SOL_SOCKET, SO_RCVBUF, &i, sizeof(int)); setsockopt(p[0], SOL_SOCKET, SO_SNDBUF, &i, sizeof(int)); setsockopt(p[1], SOL_SOCKET, SO_RCVBUF, &i, sizeof(int)); setsockopt(p[1], SOL_SOCKET, SO_SNDBUF, &i, sizeof(int)); fcntl(p[0], F_SETFL, O_NONBLOCK); fcntl(p[1], F_SETFL, O_NONBLOCK); write(p[0], crap, BUFFERSIZE); write(p[1], crap, BUFFERSIZE); } return(0); } -thanks, Greg To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
