/*
* Divert sockets
#define DIVRCVQ (65536 + 100)
/*
- * A 16 bit cookie is passed to and from the user process.
- * The user process can send it back to help the caller know
- * something about where the packet originally came from.
+ * Divert sockets work in conjunction with ipfw, see the divert(4)
+ * manpage for features.
+ * Internally, packets selected by ipfw in ip_input() or ip_output(),
+ * and never diverted before, are passed to the input queue of the
+ * divert socket with a given 'divert_port' number (as specified in
+ * the matching ipfw rule), and they are tagged with a 16 bit cookie
+ * (representing the rule number of the matching ipfw rule), which
+ * is passed to process reading from the socket.
*
- * In the case of ipfw, then the cookie is the rule that sent
- * us here. On reinjection is is the rule after which processing
- * should continue. Leaving it the same will make processing start
- * at the rule number after that which sent it here. Setting it to
- * 0 will restart processing at the beginning.
+ * Packets written to the divert socket are again tagged with a cookie
+ * (usually the same as above) and a destination address.
+ * If the destination address is INADDR_ANY then the packet is
+ * treated as outgoing and sent to ip_output(), otherwise it is
+ * treated as incoming and sent to ip_input().
+ * In both cases, the packet is tagged with the cookie.
*
- * For divert_packet(), ip_divert_cookie is an input value only.
- * For div_output(), ip_divert_cookie is an output value only.
+ * On reinjection, processing in ip_input() and ip_output()
+ * will be exactly the same as for the original packet, except that
+ * ipfw processing will start at the rule number after the one
+ * written in the cookie (so, tagging a packet with a cookie of 0
+ * will cause it to be effectively considered as a standard packet).
