dd7e261079 Cosmetic: Make our external function names consistent. 1998-05-01 19:26:12 +00:00

47723d29e5 o Use two `cat' processes to connect the modem to an
already-running ppp.
  Suggested by: Garrett Wollman <wollman@khavrinen.lcs.mit.edu>
o Use _PATH_DEVNULL rather than "/dev/null"
o Be more paranoid about nuking running timers when
  transferring links.

6f38457323 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....

49052c9523 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.

565e35e50e 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.

b6217683dc 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.

cd9647a100 o Move default MRU, MTU, ACCMAP and OPENMODE config values into
struct lcp and display them in `show lcp'.
o Remove `show mru' and `show mtu' and make the data part of
  `show lcp'.  Also merge `set m[tr]u' and `set openmode'
  implementations into the SetVariable function.
o `set timeout' only accepts the idle timer value as an argument.
o Move our lqr period into struct lcp, and create a `set lqrperiod'
  command.  Display it in `show lcp'.
o Remove VarRetryTimeout, and implement it at the LCP, PAP, CHAP,
  CCP and IPCP levels, creating individual `set XXXretry' commands
  for each.  They must be separate because they have different
  context requirements in multilink mode.
o Display default config values in `show ccp'.
o Tart the man page up a bit (wrt PPP/TCP, compression and LQR) and
  explain the new commands.

3b0f8d2ed6 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.

3bf710a4ba o Move all device names into struct physical.
o Use the correct device name in -direct mode.
o Use a default list of "cuaa1, cuaa0" rather than
  just cuaa1 and allow embedded spaces as separators.
