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.
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.
Increment OutPackets for any packet - not just LQRs
MFC:
o Fix a few comment typos.
o Fix ``set timeout'' usage message and documentation.
o Change ifOutPackets, ifOutOctets and ifOutLQRs to `u_int32_t's
so that they wrap correctly.
o Put the LQR in network byte order using the correct struct size
(sizeof u_int32_t, not sizeof u_long).
o Wrap LQR ECHO counters correctly.
o Don't increment OutLQR count if the last LQR hasn't been replied
to.
o Initialise last received LQR in StartLqm.
o Don't start the LQR timer if we're `disabled' and `accepted'.
o Generate LQR responses when both sides are using a timer and
we're not going to send our next LQR before the peers max timeout.
Struct bundle will have its own struct ccp in the future
too.
o The ``set stopped'' command now requires context and doesn't
work on the IPCP FSM.
o Check if it's time to break out of our top level loop before
doing a select - otherwise, we'll select forever :-(
o Remove `struct link'::ccp (a temporary hack). It turns out
that IpStartOutput() calls link_Output() and link_Output()
incorrectly calls StartOutput() (really modem_StartOutput)
requiring the ccp knowledge so that it can call
IpStartOutput()... The end result is that the whole IP
output queue gets dumped into the modem output queue
and a pile of physical writes are done prematurely. This
makes the (original) code in main() actually work in that
it would not bother selecting() on the tun descriptor when
our modem queue length was 20 or greater. Instead, we now
make that decision based on the overall queue length.
This will need improvement later.
o Move our LCP report timer into struct hdlc - it's really
a hdlc timer (fcs errors etc).
o Make `show hdlc' require context and make the output more
friendly.
o Remove all non-const globals from hdlc.c
o Output peer-rejected protocols by name - not just ones
that we reject.
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 !
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.
