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

b7c5748e5e o Rename datalinks as soon as the name has been received so that
LQM and HDLC timer diagnostics come out with the correct name.
o Don't send an LQR immediately upon reviving a datalink.  Leave
  it 'till the next timeout.
o Add the link name to some more LQR diagnostics.
o Break out of the main loop when a descriptor exception is seen
  in select().
o Remove the evil nointr_[u]sleep() functions.  Timers should be
  (and are) used instead.
o Treat a read() of 0 bytes as an error that's fatal to the link
  on which the read() is done.  We should never read() 0 after
  select() says there's something there - not unless the link
  has been closed by the other side.
o Write the data seen before a HDLC header to the terminal in
  `term' mode, *not* back to the modem :-/
o Initialise our transmitted file descriptor before starting any
  timers.
o Only send data links that have *no* pending output data.  This
  means that our final ACK will be written rather than being
  nuked with the datalink transmission.

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

2764b86afd o Move alias function pointers into loadalias.c
o Move Var*Version into command.c
o Remove struct pppVars (and there was much rejoicing) !
o Forward-decl some structs in .h files to avoid include
  ordering requirements and remove a few more redundant
  #includes.

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.

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.

b1cbb71c91 Don't expect select() to adjust the passed time when it's
interrupted with a SIGALRM.  In fact, select() sets the
passed time to zero, making the previous implementation
terminate always after 1/10th of a second !

Also, deal with someone changing the clock while we're
sleeping (and restart the whole sleep).

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).
