Hello, Is it possible somehow to create a TCP socket from kernel and to send a message when you are in interrupt context ? I made a test : I created a kernel socket with sock_create_kern(PF_INET, SOCK_STREAM, IPPROTO_TCP, &sock) and then connected it with: sock->ops->connect(sock, (struct sockaddr*)&addr, sizeof(struct sockaddr), 0) When working NOT in interrupt context,it works OK; I called : kernel_sendmsg(sock, &msg, &iov, 1, length); and a TCP packet WAS sent (I verified it with a sniffer) BUT, in interrupt context, I called : kernel_sendmsg(sock, &msg, &iov, 1, length); I got: Feb 22 12:02:54 markhost kernel: BUG: sleeping function called from invalid context Feb 22 12:02:54 markhost: in_atomic():1, irqs_disabled():0 Why is it so ? is there another way create a kernel TCP socket and to send a packet?
