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 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.
is available, but LCP hasn't yet been started. We get to this
state in ``term'' mode.
Remove PacketMode(). LCP startup and shutdown is now controlled
by the datalink.
Add ``show links'' command.
Make ``close'' capable of running with and without a context.
Make ``down'' require a context.
Make ``set parity'' and ``set rtscts'' use the correct context.
datalink_Up() can now be told to skip the dial/login/hangup
scripts and can be told whether to enter packet mode when
entering the DATALINK_OPENED state.
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 !
Allow for NULL fd_sets in descriptor_UpdateSet()
Reimplement the entire chat module, creating
`struct chat' - a `type' of struct descriptor.
Remove CARRIER logging.
CONNECT logging now only logs "CONNECT" lines. CHAT logging
masks it with an entire log of the conversation.
Modem dialing is now asynchronous, including pauses
and timeouts :-)
The hooks in DoLoop() in main.c are *very* messy ! I'll have
to rewrite DoLoop fairly soon, so I don't care too much for the
moment. This code is pretty raw.
This will ultimately be a member of a list of descriptors and
their handler functions on which we need to select() in the
main loop.
o Make struct physical into a `sort' of struct descriptor.
o Don't remove routes and DOWN the interface when we're
closed in auto mode.
o Initialize the FSMs in bundle_Create.
o Initialize ipcp::if_mine & ipcp::if_peer only once (so
that we don't forget that we've SIOCAIFADDR'd the interface).
o Do a SIOCDIFADDR on the specific address to avoid hurting any
other (still non-existent) NCPs.
o Fix some error/diagnostic messages.
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.
