Make the code format more in line with style(9). Update loadalias to use the new libalias api. Update to version 1.1. 1997-08-25 00:29:32 +00:00			`#define PROTO_IP 0x0021 /* IP */`
			`#define PROTO_VJUNCOMP 0x002f /* VJ Uncompressed */`

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. 1998-04-03 19:21:56 +00:00			`#define PROTO_MP 0x003d /* Multilink fragment */`

o Activate link-level CCPs in multilink mode, by bringing them into the ST_STOPPED state. o Allow an optional ccp\|lcp argument to `down'. The default is still lcp (as before). You can now call down with no context in multilink mode, in which case it'll down the multilink ccp or the entire bundle (very rude). o Allow an optional `!' after `close ccp' (close ccp!) to tell ccp to stay in the CLOSED state after the terminate ACK. The default is now to re-enter STOPPED so that the peer can bring the layer back up if desired. o Always handle proto-compressed packets, even if we've agreed (in LCP) that the peer will not send us 1 byte protocols. If the peer violates the LCP agreement, log it to the HDLC log. o Fix some comments. 1998-05-15 18:21:12 +00:00			`#define PROTO_COMPRESSIBLE(p) (((p) & 0xffe1) == 0x21)`
