d93d3a9c32 o De-staticise things that don't need to be static.
o Bring the static ``ttystate'' into struct prompt so that
  the tilde context is per prompt and not global.
o Comment the remaining static variables so that it's
  clear why they're static.
o Add some XXX comments suggesting that our interface list
  and our hostname should be re-generated after a signal
  (say SIGUSR1) so that a machine with PCCARDs has a chance.

81358fa3fc o Make modes consistent throughout ppp. The same strings are used
in `set mode', `allow modes', on the command line and when
  outputting mode names.  The strings are matched so that only
  enough characters to uniquely identify the string are required,
  so you can now

    ppp -a mylabel  (for auto mode)
    ppp -b mylabel  (for background mode)
    ppp -dd mylabel (for direct dial mode)

  etc.
o Make -ddial dial when specified on the command line (oops).

1662ac2427 srandomdev() isn't available in all 2.* versions. Only
use it for version 3 (-current) & up.

d91d286164 MFMP: Make ppp multilink capable.
See the file README.changes, and re-read the man page.

dd0645c5b7 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.

1bc9b5ba84 o Make sure we don't dereference NULL when we've lost all our links.
o Use srandomdev() for __FreeBSD__ >= 2, not just >2.
o Use srandom((time(NULL)^getpid())+random()), random() when we
  haven't got srandomdev().

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.

5cf4388bdf Tidy up the parent notification stuff for -background mode.

1e991daad5 Remove some more globals:
o int modem was unused.
  o StateNames[] is now accessed via State2Nam()
  o ipKeepAlive is no more.  As a result, we must call FilterCheck()
    twice if we're doing TCP/IP logging (once when we queue and log
    the packet and once when we transmit it and need to know if the
    idle timer should be reset), but this won't be the case
    in normal life.

85b542cf4f Move the terminal/diagnostic socket stuff out of main.c
and into the new `prompt.c'.  struct prompt is (of course)
a `sort' of descriptor.

7a6f872047 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.

247ab36d28 o Move in_algorithm and out_algorithm into CcpInfo.
o Take note of the return value of the compression layers
  init routine, and if it fails, bring the whole layer
  cleanly back down again.
o Only use srandomdev() if ``__FreeBSD__ > 2'' - this makes
  these sources buildable on 2.2 (where I'm testing).

b6e82f33ef Fix prototypes.
Remove extraneous decls.
Add ``const'' to several places.
Allow ``make NOALIAS=1'' to remove IP aliasing.
Merge with OpenBSD - only the Makefiles vary.

We can now survive a compile with
  -Wall -Wbad-function-cast -Wcast-align -Wcast-qual
  -Winline -Wmissing-declarations -Wmissing-prototypes
  -Wnested-externs -Wpointer-arith -Wredundant-decls
  -Wshadow -Wstrict-prototypes -Wwrite-strings -Wchar-subscripts
(although the Makefile just contains -Wall).

12ef29a81a Finish the security improvements:
o Add "allow" command:
      "allow users a b c" gives access to users a, b and c.
      "allow modes auto"  gives those users access to auto mode only.
      "allow users *" and  "allow modes *" are accepted.
      No users and all modes are allowed by default.
    UID 0 can do anything.
  o Set the current label with the "load" and "dial" commands
    so that the call to ppp.linkdown makes sense.
  o Up the verison number.
  o Don't OR MODE_AUTO for -background and -ddial.
  o Don't OR MODE_INTER when we get a diagnostic connection.
  o Allow up to 40 args per line (was 20).
  o "set ifaddr" only changes the interface in AUTO mode (with other
    modes, it happens after IPCP negotiation).
  o Sort command descriptions in the man page.
  o Support -dedicated mode where we just talk ppp forever (no login etc).
