With this, modules +below ip can be inserted, or removed, without having the ip stream be +unplumbed, and re-plumbed again. All states in ip for an interface +will therefore now be preserved. Users can install (or upgrade) +modules like firewall, bandwidth manager, cache manager, tunneling, +etc., without shutting the machine down. + +To support this, ppp driver now uses /dev/udp instead of /dev/ip for +the ip stream. The interface stream (where ip module pushed on top of +ppp) is then I_PLINK'ed below the ip stream. /dev/udp is used because +STREAMS will not let a driver be PLINK'ed under itself, and /dev/ip is +typically the driver at the bottom of the tunneling interfaces +stream. The mux ids of the ip streams are then added using +SIOCSxIFMUXID ioctl. + +Users will be able to see the modules on the interface stream by, for +example: + + pikapon% ifconfig ppp modlist + 0 ip + 1 ppp + +Or arbitrarily if bandwidth manager and firewall modules are installed: + + pikapon% ifconfig hme0 modlist + 0 arp + 1 ip + 2 ipqos + 3 firewall + 4 hme + +Snoop Support. +************** + +This version includes support for /usr/sbin/snoop. Tests has been done +on both Solaris 7 and 8. Only IPv4 and IPv6 packets will be sent up to +stream(s) marked as promiscuous, e.g, snoop et al. + +Users will be able to see the packets on the ppp interface by, for example: + + snoop -d ppp0 + +See the man page for snoop(1M) for details. + IPv6 Support. ************* +This is for Solaris 8 and later. + This version has been tested under Solaris 8 running IPv6.
