by sending a SIGINT to the child. This was intended before, but
pending_signal() was wrongly used - resulting in no action being
taken as the parent will never enter the main processing loop.
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.
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.
This structure contains the asynchronous state of the physical
link.
Unfortunately, just about every .h file is included in every .c
file now. Fixing this can be one of the last jobs.
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 Use INADDR_ANY and INADDR_BROADCAST instead of 0 and 0xffffffff
for IP addresses & masks.
o Move struct compreq into ipcp.c (it's none of anyone elses
business).
o Rename MAX_STATES to MAX_VJ_STATES.
