Introduce ID0 logging. Stay as the invoking uid as much as possible. Execution as a normal user is still forbidden for now, so these changes are pretty ineffective. The next commit will implement the modifications suggested on -hackers a number of days ago.

MFMP: Allow 8 character login names. Do the login()/logwtmp()/logout() as id 0.

struct utmp;
o Add the link name to modem diagnostics. o Create struct mpserver as part of struct mp. mpserver creates a unix-domain socket based on the peers auth name and endpoint discriminator. If it already exists, ppp will ``pass the link'' over to the owner of the socket, joining it into the bundle of another ppp invocation, otherwise ppp waits for other invocations to pass it links through this socket. The final piece of code will be the code that flattens our datalink info and passes it down this channel (not yet implemented).

Support client side DNS server negotiation, disabled and denied by default (POLA). o Remove ``enable'' msext. Now, doing a ``set nbns'' will automatically enable a NBNS ACK/NAK rather than a REJ. o Add accept|disable|deny|enable dns. If we ``accept'', we'll tell the peer what our nameservers are (if he asks). The values in resolv.conf can be overridden with the ``set dns'' command. If we ``enable'', we'll REQ using our resolv.conf entries, and any NAKs are written back to resolv.conf. o Remove ``show msext'' and show the relevent IP numbers in ``show ipcp''.

Write to the routing socket as uid 0. It's not good enough to just open it as uid 0 under OpenBSD.

o Create a new ``timer'' log level. This lets us ``set log debug'' without filling our filesystem/screen with junk that we don't really want to see. o change PHYS_STDIN to PHYS_DIRECT - we can handle incoming connections that aren't on STDIN_FILENO now. o Allow return values from our FSM LayerUp functions. If LayerUp() fails, the FSM does an immediate FsmDown() without calling the fsm_parent's Layer{Up,Down} functions. o Clear the close-on-exec flag of file descriptor 3 when executing chat programs so that our documented ability to communicate with /dev/tty via that descriptor works. Also document it as descriptor 3, not 4 :-O o Allow a ``rm'' command as an alias for ``remove''. o Fix the bind()/connect()/accept() calls made by the MP server. o Create bundle_SendDatalink() and bundle_ReceiveDatalink(). This allows `struct datalink's to flatten themselves, pass through a pipe (read: the eye of a needle !) and come alive at the other end. The donator then fork()s & exec()s pppmpipe, ``passing'' the connection to another ppp instance. *** PPP NOW TALKS MULTILINK :-))) *** Our link utilization is hideous, and lots of code needs tidying still. It's also probably riddled with bugs ! It's been tested against itself only, and has hung once, so confidence isn't high....

extern int ID0connect_un(int, const struct sockaddr_un *);
o If there's a session leader left running for a descriptor that we're now closing, manually HUP that session leader so that the tty is fully released. o Always restart our carrier detect timer in the receiving process if it was running in the sending process (as we now *always* pass the descriptor). o Tweak argv when we go into pause() mode to keep our session so that ps can see what's going on (without checking for a `pause' state in `ps -l').
