Create `struct bundle' - the top level control structure. This structure will eventually contain a list of NCPs (currently only IPCP is supported) and a list of physical `struct link's. It will also derive from a struct link itself. Make ModemTimeout() static - it's way to dangerous to be called from outside ! Bump version to 1.9. Our first MP release should be 2.0.

o Move our prompt descriptor list outside of the bundle. It's now dealt with by the `server' object. This simplifies things as we only have one list of prompt descriptors and the log_ routines check prompt::logactive to determine whether it should be used for output. o Include the MP socket UpdateSet() result in bundle::UpdateSet(). o Don't select on the tun device unless we're in NETWORK phase or AUTO mode. o Stop the idle timer when we go to DEAD phase. We may have transferred a link and not had a chance to kill it. o Don't fail when trying to unlink our transferred datalink from our descriptor lists just before the transfer. o Add our link descriptor to the write set if we got a short write the last time (physical::out is set). o Log the connection source address when a connection is closed. o Remove descriptor::next field. Descriptor lists are not required any more.

o Hook the FSMs into our bundle. o The FSM layering is now more sane. o Move a lot of the NCP stuff into our ipcpstate rather than having it in the bundle, including control of the configured IP addresses. We don't need hacks like the global `linkup' variable any more as the FSM decides when our ppp.link* files get run. This is going to eventually be configurable based on FSM events anyway. o Fix a few inconsistencies when both sides require authentication. o We now have "Ppp..." and "PPp" prompts, reflecting authentication and network phase. We don't print loads of spurious prompts as we change phases any more. o Our phase is part of the bundle now. o Fix a bug where the FSM wasn't calling LayerFinish. o Close the FSM down correctly with a signal rather than slamming it down as if the line was dropped (the undocumented ``down'' command is still available though). o Remove the forgotten `tunno' variable and fix references to it.

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''.

Create `struct sticky_route'. Any `add' or `delete' command that uses MYADDR or HISADDR will be added to the sticky route list (show ipcp). When MYADDR or HISADDR change due to IPCP negotiations, and if `sroutes' is enabled (the default), all sticky route entries are updated in the routing table. The end result is that `add default hisaddr' will ``stick'', as will ``add myaddr 255.255.255.255 127.0.0.1'' and ``add 1.2.3.4 255.255.255.0 hisaddr''.

Negotiate MRRU, SHORTSEQ and ENDDISC. ENDDISC doesn't imply multilink ('cos I've seen my ISP REQ it without multilink). Setting MRRU is ifdef'd out until it's debugged and we can merge -direct links with other running programs. Fix MTU setting.

Move filter sets into struct bundle.

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 !

1998-02-06 02:24:29 +00:00
struct link;
Deglobalise `struct prompt': o Our diagnostic socket has its password set in the `set socket' line only (not in ppp.secret). o Passwords are per server socket (*VarAuthKey are gone) o Authority is per prompt (VarLocalAuth is gone). o Local logging is per prompt. o Add a `show who' command to see who's connected. No identd routine - just a `where the connection came from' display. o SIGUSR1 is disabled for now - we have no way of choosing a password for the socket created :-( Prompts are attached as a list of `struct descriptor's in struct bundle, and serviced under the bundles descriptor service routines. Ultimately, everything should be done like this. Cosmetic: o alphabeticalise SRCS in Makefile. o Add a few comments in command.h TODO: Start checking that we don't overflow the descriptor sets in select() now that we can have any number of descriptors.

u_int phase; /* Curent phase */
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.

Move the IPCP into struct bundle.
1998-03-13 21:07:46 +00:00
struct {
struct ipcp ipcp; /* Our IPCP FSM */
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.

extern void bundle_Down(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.

extern void bundle_Open(struct bundle *, const char *, int);
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 void bundle_LinkClosed(struct bundle *, struct datalink *);
extern int bundle_FillQueues(struct bundle *);
Introduce the ``link'' command for controlling individual links.

extern int bundle_ShowLinks(struct cmdargs const *);
Remove ``show timeout'' and ``show auth'' and add ``show bundle''. Mention ``show timer'' in the man page.
1998-04-11 21:50:47 +00:00
extern int bundle_ShowStatus(struct cmdargs const *);
Move the idle timer into struct bundle. There's no link-level idle timer for the moment.

extern void bundle_StartIdleTimer(struct bundle *);
extern void bundle_SetIdleTimer(struct bundle *, int);
extern void bundle_StopIdleTimer(struct bundle *);
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
extern int bundle_IsDead(struct bundle *);
Shuffle around our FSMs a bit. This'll make it easier to remove the CcpInfo, LcpInfo and IpcpInfo globals.

extern struct datalink *bundle2datalink(struct bundle *, const char *);
Deglobalise `struct prompt': o Our diagnostic socket has its password set in the `set socket' line only (not in ppp.secret). o Passwords are per server socket (*VarAuthKey are gone) o Authority is per prompt (VarLocalAuth is gone). o Local logging is per prompt. o Add a `show who' command to see who's connected. No identd routine - just a `where the connection came from' display. o SIGUSR1 is disabled for now - we have no way of choosing a password for the socket created :-( Prompts are attached as a list of `struct descriptor's in struct bundle, and serviced under the bundles descriptor service routines. Ultimately, everything should be done like this. Cosmetic: o alphabeticalise SRCS in Makefile. o Add a few comments in command.h TODO: Start checking that we don't overflow the descriptor sets in select() now that we can have any number of descriptors.

extern void bundle_CleanDatalinks(struct bundle *);
Negotiate MRRU, SHORTSEQ and ENDDISC. ENDDISC doesn't imply multilink ('cos I've seen my ISP REQ it without multilink). Setting MRRU is ifdef'd out until it's debugged and we can merge -direct links with other running programs. Fix MTU setting.

extern void bundle_SetLabel(struct bundle *, const char *);
extern const char *bundle_GetLabel(struct bundle *);
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 !

extern void bundle_SendDatalink(struct datalink *, int, struct sockaddr_un *);
extern void bundle_ReceiveDatalink(struct bundle *, int, struct sockaddr_un *);
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.
