Hi, Consider the following scenario: A daemon is waiting on accept() on a socket in the user space. It receives a new connection and sends the socket descriptor down to a module waiting for it in the kernel using ioctl(). The module gets the socket behind the descriptor using fget() and socki_lookup() on the inode. The module spawns a kernel thread that now reads from that socket. Everything is working great even if the daemon now closes the new socket. The session remains open and there is data transfer. The problem is that if the deamon dies for whatever reason, the kernel thread returns from the read with -512 (ERESTARTSYS) and the socket can no longer be used. I tried several things including raising the count on the inode and the file structure. Nothing helped. I'de appreciate any ideas.
