bundle (non-negotiated vars) or to their respective IPCP,
LCP or CCP.
o Enable rolling throughput statistics by default.
o Remove the `display' command. These values now appear in
`show bundle', `show ipcp', `show ccp' and `show lcp'.
o Initialise auth name & key at bundle create time (oops).
o Rename pppd-deflate (the id-24 hack) to deflate24.
o Don't send both a REJ and a NAK to an IPCP or LCP REQ.
Favour the REJ (already done at the CCP level).
o Recurse in datalink_UpdateSet() when we change state, otherwise
we end up setting no descriptors and getting jammed in the
imminent select() instead of doing the dial/login/hangup.
o Display our CHAP encryption method despite being built with DES.
o Display VJ as not negotiated in ``show ipcp'' when necessary.
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.
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.
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.
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.
packets when we haven't agreed a protocol).
o Move the complication of passing incoming data to the
PROTO_COMPD input or dictionary setup routine into ccp.c
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.
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.
IPCP, CCP and LCP are now just derived FSMs.
Comment each of the FSM implementations so that we can
tell what's going on.
Revise the state transitions so that CCP and IPCP actually
send terminate REQs when appropriate.
The OS & IPCP layers are still like spagetti (next job).
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).
