Hi. I don't know much about pppd so this may be completely wrong. Suppose this setup: I have a custom kernel which "secures" sockets. That is, any program that will try to use a socket without "unlocking" it first, will get some ERROR. This way, only trusted programs will be able to use sockets and connect to the net. So, sockets are secured at the TCP/IP layers. My question now is, if it is possible to attack this by sending data directly to the PPP layer. Can one open /dev/ppp, construct a UDP packet, encapsulate this into a PPP packet, write it to some /dev/ppp device and reach some internet host?
