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 !

Add datalink state DATALINK_READY to indicate when the datalink is available, but LCP hasn't yet been started. We get to this state in ``term'' mode. Remove PacketMode(). LCP startup and shutdown is now controlled by the datalink. Add ``show links'' command. Make ``close'' capable of running with and without a context. Make ``down'' require a context. Make ``set parity'' and ``set rtscts'' use the correct context.

Do authentication at the datalink level, not the bundle level. The bundle doesn't get a LayerUp 'till we're authenticated. Introduce DATALINK_LCP and DATALINK_AUTH phases.

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 !

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.

o Defer setting up pap/chap based IP numbers & labels until after we've determined if we're going to join another ppp invocation. o Make ``show link'' show all link details, and ``show links'' just give a list of links and their current status. o Show our current label in ``show bundle''. o Allow link cloning and removal as soon as our MRRU is set. o Make ``show lcp'' require context as nothing will ever change in our MP LCP (it's auto-configured as per rfc1990). o Initialise our LQM owner in hdlc_Init(). o Store our endpoint discriminator and authentication name at both the datalink and multilink level and compare them when we've finished AUTHENTICATE phase and before entering NETWORK phase. If they don't match, close the link again. Display the information in the appropriate ``show'' command. o Initialise datalink::phone and datalink::fsmp.object properly when we're cloning the link. o Show which link we're passing LQRs on in our diagnostics. o Reject endpoint discriminator REQs at the logical multilink level. o Remove the rest of our CARRIER and LINK logging setup.
1998-04-24 19:16:15 +00:00
struct peerid peer; /* Peer identification */
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.

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....

Display the information in the appropriate ``show'' command. o Initialise datalink::phone and datalink::fsmp.object properly when we're cloning the link. o Show which link we're passing LQRs on in our diagnostics. o Reject endpoint discriminator REQs at the logical multilink level. o Remove the rest of our CARRIER and LINK logging setup.

extern void datalink_Rename(struct datalink *, const char *);
Log link name changes correctly.

o Call bundle_LinkClosed() when transferring a datalink so that the bundle has the opportunity to go PHASE_DEAD and cleanup the interface (if it's the last link). o Regnerate our phys_type value when we transfer the link. o Always clean up the interface when destroying our bundle in case we're abending. o Always clean up our interface when the last link is gone rather than delaying things 'till exit time in the -direct case (the interface is useless anyway). Do this *after* slamming down our NCPs (if they're still around). o Our MP server descriptor now clears the relevent device descriptor from our descriptor [fd]sets when a datalink is on death-row (to be transferred to another running ppp), thus avoiding the possibility of passing a bum descriptor to select() and having ppp abend. o Handle the MP socket descriptor functions from within the bundle descriptor functions. Now we ensure that the MP socket descriptor functions see the descriptor sets *after* they've been seen by our datalinks. o Add/fix a few more comments.

fd_set *);
o Add the `set mode' command for change a links current mode. It is not possible to switch to or from dedicated or direct mode, but all other combinations are ok (eg. -auto -> -ddial). o Cope with the fact that commands with optional context may not be able to obtain a link with command_ChooseLink() (if all links have been deleted for example). o Allow `clone'ing in non-multilink mode. We may for example want to configure two links in unilink mode and dial them both, using the one that comes up first. It's also possible to rename ``deflink'' by cloning it, deleting the original, then setting the mode of the new link.
