Hi all, I am creating a socket in kernel. It is able to bind. But after abnormal termination of the module, I am not able to bind the socket once again. Here i use ....................................................................... /* create a socket */ if ((err = sock_create(AF_INET, SOCK_DGRAM, IPPROTO_UDP, &sock)) < 0) { printk(KERN_INFO MODULE_NAME": Could not create a datagram socket, error = %d\n", -ENXIO); return; } if((err = sock->ops->setsockopt(sock, SOL_SOCKET, SO_REUSEADDR, (void*)&option, sizeof(option)))<0) printk(KERN_INFO MODULE_NAME": Error in set socket opt for SO_REUSEADDR \n"); memset(&addr, 0, sizeof(struct sockaddr)); addr.sin_family = AF_INET; addr.sin_addr.s_addr = htonl(INADDR_ANY); addr.sin_port = htons(7006); if ((err = sock->ops->bind(sock, (struct sockaddr *)&addr, sizeof(struct sockaddr)))< 0) { printk(KERN_INFO MODULE_NAME": Could not bind to socket, error = %d\n", -err); goto close_and_out; } printk(KERN_INFO MODULE_NAME": listening on port %d\n", 7006); ................................................................... It throwing the following error Error in set socket opt for SO_REUSEADDR Could not bind to socket, error = 98 Can you tell me what i am missing. Just I want to reuse the bind same address once again in the same port. Thanks. Chinmaya -- Kernelnewbies: Help each other learn about the Linux kernel.
