o Transfer file descriptors using {send,recv}msg & SCM_RIGHTS, using the scatter/gather array to transfer the link information. The whole link is now passed in one message. This is far better than the two `/bin/cat' processes per additional link :-) I remember years ago thinking that file descriptor transferral would be a really amazing facility !

Create struct datalink. This is a type of physical link that can chat and talk LCP & CCP. A bundle contains a list of these (only one in the list for the moment). The datalink is a type of descriptor, and dials, enters LCP (& does CCP), kicks the bundle when its FSMs do something interesting and does the hangup chat script on the way down. It also handles redials and reconnects. There are lots of loose ends, and probably lots of bugs, but the data structures are getting there !

extern int modem_Raw(struct physical *, struct bundle *);
o Remove the `mode' global - it's now per physical device. o Shuffle things that live at the datalink level into ``show link'' rather than ``show modem''. o Make both ``show'' commands prettier and more consistent, and display carrier status, link type and our name in ``show modem''. o Show redial and reconnect information in ``show link'' and remove ``show redial'' and ``show reconnect''. o Down the correct link in bundle_LinkLost(). o Remove stale -direct and -background links at the end of our main loop, not when we know they're going. This prevents unexpected pointer-invalidations... o If we ``set server'' with the same values twice, notice and don't moan about failure. o Record dial script despite our link mode. The mode may be changed later (next mod) :-) We never run scripts in -direct and -dedicated modes. o Make ``set server none'' functional again. o Correct datalink state array so that we don't report an ``unknown'' state. o Pass struct ipcp to IpcpCleanInterface, not struct fsm. o Create TUN_PREFIX define rather than hard-coding in main.c o prompt_TtyInit now handles a NULL prompt for -direct mode rather than having to create one then destroy it uncleanly. o Mention our mode in the "PPP Started" LogPHASE message. o Bring all auto links up when we have something to send. o Remove some redundant Physical_*() functions. o Show which connection is running a command when logging commands. o Initialise throughput uptime correctly.

Overhaul ppp: o Use syslog o Remove references to stdout/stderr (incl perror()) o Introduce VarTerm - the interactive terminal or zero o Allow "set timeout" to affect current session o Change "set debug" to "set log" o Allow "set log [+|-]flag" o Make MSEXT and PASSWDAUTH stuff the default o Move all #ifdef DEBUG stuff into the code - this shouldn't be too much overhead. It's now controlled with "set log +debug" o Add "set log command, debug, tun, warn, error, alert" o Remove cdefs.h, and assume an ansi compiler. o Improve all diagnostic output o Don't trap SIGSEGV o SIGHUP now terminates again (log files are controlled by syslog) o Call CloseModem() when changing devices o Fix parsing of third arg of "delete" I think this fixes the "magic is same" problems that some people have been experiencing. The man page is being rewritten. It'll follow soon.

Update to version 2.0-beta Allow for NULL fd_sets in descriptor_UpdateSet() Reimplement the entire chat module, creating `struct chat' - a `type' of struct descriptor. Remove CARRIER logging. CONNECT logging now only logs "CONNECT" lines. CHAT logging masks it with an entire log of the conversation. Modem dialing is now asynchronous, including pauses and timeouts :-) The hooks in DoLoop() in main.c are *very* messy ! I'll have to rewrite DoLoop fairly soon, so I don't care too much for the moment. This code is pretty raw.

extern void modem_Offline(struct physical *);
o Move struct lcp and struct ccp into struct link. o Remove bundle2lcp(), bundle2ccp() and bundle2link(). They're too resource-hungry and we have `owner pointers' to do their job. o Make our FSM understand LCPs that are always ST_OPENED (with a minimum code that != 1). o Send FSM code rejects for invalid codes. o Make our bundle fsm_parent deal with multiple links. o Make timer diagnostics pretty and allow access via ~t in `term' mode (not just when logging debug) and `show timers'. Only show timers every second in debug mode, otherwise we get too many diagnostics to be useful (we probably still do). Also, don't restrict ~m in term mode to depend on debug logging. o Rationalise our bundles' phases. o Create struct mp (multilink protocol). This is both an NCP and a type of struct link. It feeds off other NCPs for output, passing fragmented packets into the queues of available datalinks. It also gets PROTO_MP input, reassembles the fragments into ppp frames, and passes them back to the HDLC layer that the fragments were passed from. ** It's not yet possible to enter multilink mode :-( ** o Add `set weight' (requires context) for deciding on a links weighting in multilink mode. Weighting is simplistic (and probably badly implemented) for now. o Remove the function pointers in struct link. They ended up only applying to physical links. o Configure our tun device with an MTU equal to the MRU from struct mp's LCP and a speed equal to the sum of our link speeds. o `show {lcp,ccp,proto}' and `set deflate' now have optional context and use ChooseLink() to decide on which `struct link' to use. This allows behaviour as before when in non-multilink mode, and allows access to the MP logical link in multilink mode. o Ignore reconnect and redial values when in -direct mode and when cleaning up. Always redial when in -ddial or -dedicated mode (unless cleaning up). o Tell our links to `staydown' when we close them due to a signal. o Remove remaining `#ifdef SIGALRM's (ppp doesn't function without alarms). o Don't bother strdup()ing our physical link name. o Various other cosmetic changes.
