7e778f13d9 Rather than interrupting 10 times per second then checking
to see if there's anything to do, schedule the next alarm
based on the next required timeout.
This decreases the load when there are lots of relatively
idle ppp processes.

While I'm in there, handle the possibility that a timeout
makes the timer element go out of scope by grabbing the
enext pointer before executing the timer function.

d2a69fc3ba Re-initialise our timer service after fork()ing
to lose our terminal session.  Is this a bug in
setitimer() ? - it must be called again in the
child !

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).
