Message-ID: <46995671.5080503@simon.arlott.org.uk> Date: Sun, 15 Jul 2007 00:04:17 +0100 From: Simon Arlott <simon@...e.lp0.eu> To: netdev@...r.kernel.org Subject: open() on sockets (sock_no_open) There are sockets in /proc/<pid>/fd/, but they can't be opened because of this function: /* * In theory you can't get an open on this inode, but /proc provides * a back door. Remember to keep it shut otherwise you'll let the * creepy crawlies in. */ static int sock_no_open(struct inode *irrelevant, struct file *dontcare) How would I make it possible to open existing sockets? It's possible to duplicate access to the same socket using fork(), but I just seem to be creating a mess when I try to make open() work because it breaks after calling socket_close... is there a way to do this so it works properly? -- Simon Arlott - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
