log debug'' without filling our filesystem/screen with
junk that we don't really want to see.
o change PHYS_STDIN to PHYS_DIRECT - we can handle incoming
connections that aren't on STDIN_FILENO now.
o Allow return values from our FSM LayerUp functions. If
LayerUp() fails, the FSM does an immediate FsmDown() without
calling the fsm_parent's Layer{Up,Down} functions.
o Clear the close-on-exec flag of file descriptor 3 when executing
chat programs so that our documented ability to communicate with
/dev/tty via that descriptor works. Also document it as
descriptor 3, not 4 :-O
o Allow a ``rm'' command as an alias for ``remove''.
o Fix the bind()/connect()/accept() calls made by the MP server.
o Create bundle_SendDatalink() and bundle_ReceiveDatalink().
This allows `struct datalink's to flatten themselves, pass
through a pipe (read: the eye of a needle !) and come alive
at the other end. The donator then fork()s & exec()s pppmpipe,
``passing'' the connection to another ppp instance.
*** PPP NOW TALKS MULTILINK :-))) ***
Our link utilization is hideous, and lots of code needs
tidying still. It's also probably riddled with bugs !
It's been tested against itself only, and has hung once,
so confidence isn't high....
o Create struct mpserver as part of struct mp.
mpserver creates a unix-domain socket based on the
peers auth name and endpoint discriminator. If it
already exists, ppp will ``pass the link'' over to
the owner of the socket, joining it into the bundle
of another ppp invocation, otherwise ppp waits for
other invocations to pass it links through this
socket.
The final piece of code will be the code that flattens
our datalink info and passes it down this channel
(not yet implemented).
we've determined if we're going to join another ppp invocation.
o Make ``show link'' show all link details, and ``show links''
just give a list of links and their current status.
o Show our current label in ``show bundle''.
o Allow link cloning and removal as soon as our MRRU is set.
o Make ``show lcp'' require context as nothing will ever change
in our MP LCP (it's auto-configured as per rfc1990).
o Initialise our LQM owner in hdlc_Init().
o Store our endpoint discriminator and authentication name at both
the datalink and multilink level and compare them when we've
finished AUTHENTICATE phase and before entering NETWORK phase.
If they don't match, close the link again.
Display the information in the appropriate ``show'' command.
o Initialise datalink::phone and datalink::fsmp.object properly
when we're cloning the link.
o Show which link we're passing LQRs on in our diagnostics.
o Reject endpoint discriminator REQs at the logical multilink
level.
o Remove the rest of our CARRIER and LINK logging setup.
o change the default link name to ``deflink'' rather
than ``default''.
o Prepend the link name to CCP and LCP FSM diagnostics.
o Protect against 0 length options in CCP and IPCP REQ
interpreters (already done for LCP).
o Allow optional context for the `show' command.
o Use MPs link when interpreting commands if the multilink
mrru is configured rather than when multilink is active.
This means that once we've ``set mrru xxx'', we then need
to ``link deflink show ccp'' etc if we want to do link-level
stuff (based on the command requiring optional or manditory
context).
o Use the ifconfig'd interface address in `set enddisc {ip,mac}'
if it's there, otherwise the configuration file value.
first link in mp_Up().
o Bring MP and its CCP down when we enter phase TERMINATE,
and ditch everything in the incoming packet queue.
o Enable MRRU negotiation. Now, we can multilink
mode, but only with one physical link.
o Close the link if the peer PROTO REJs PROTO_MP.
o Prepend our protocol before passing a packet to
struct mp for fragmentation.
o Log info messages to DEBUG, not ERROR (oops).
o Align `show mp' output (again).
call it after link authentication.
o Pretty print our bundle MTU.
o Correct MP header encoding and decoding (should be network byte order).
o Add some debug diagnostics so that we can see MP fragment sending and
re-assembly.
o Don't go multilink if the peer hasn't agreed
o When negotiating multilink, don't try to push the peers
MRU up according to our `set mtu' setting. Instead, accept
whatever MRU they want and push their MRRU up instead.
o When *not* negotiating multilink, REJ short sequence number
REQs.
multilink ('cos I've seen my ISP REQ it without multilink).
Setting MRRU is ifdef'd out until it's debugged and we can
merge -direct links with other running programs.
Fix MTU setting.
o Make sure our ipcp throughput timer is stopped before being nuked
with a memset.
o Don't initialise struct async & struct hdlc twice in modem_Create().
o Clarify some comments.
enabled since we first REQ'd.
o Delete the allocated options when CCP is down (TLF).
o Clean the IPCP interface on the way down when we're
*not* in auto mode (rather than when we are) - typo.
o Don't produce two similar IpcpLayerUp messages.
and denied by default (POLA).
o Remove ``enable'' msext. Now, doing a ``set nbns'' will
automatically enable a NBNS ACK/NAK rather than a REJ.
o Add accept|disable|deny|enable dns. If we ``accept'',
we'll tell the peer what our nameservers are (if he asks).
The values in resolv.conf can be overridden with the
``set dns'' command. If we ``enable'', we'll REQ using
our resolv.conf entries, and any NAKs are written back to
resolv.conf.
o Remove ``show msext'' and show the relevent IP numbers in
``show ipcp''.
call datalink_Down() where appropriate rather than
modem_Hangup().
o Now, when something horrible happens (failed read/write, loss
of carrier etc), we go offline and run any hangup scripts etc
in a controlled manner - exactly the same as if someone says
``down'' at the prompt or sends us a HUP.
o -dedicated links that fail to make the modem raw close it,
suffer the redial timeout then try to open it again.
o Add a ``carrier lost'' warning diagnostic.
is particularily useful when creating dial filters.
Original work by: Junichi SATOH (junichi@astec.co.jp)
o Parse a filter IP of ``0.0.0.0'' as having a width of 0,
not 32.
o Correct "set filter" usage message.
o Warn about bad filter names.
o Expand and correct a number of the man page sections.
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.
expect-send-send !
o Say `disabled' rather than 0s in `show timeout'.
o Set all arguments in ``set device'' rather than just
the first (read: quotes aren't necessary).
o Set the device speed correctly (broken in last commit).
o Shuffle things that live at the datalink level into
``show link'' rather than ``show modem''.
o Make both ``show'' commands prettier and more consistent,
and display carrier status, link type and our name in
``show modem''.
o Show redial and reconnect information in ``show link''
and remove ``show redial'' and ``show reconnect''.
o Down the correct link in bundle_LinkLost().
o Remove stale -direct and -background links at the end
of our main loop, not when we know they're going. This
prevents unexpected pointer-invalidations...
o If we ``set server'' with the same values twice, notice
and don't moan about failure.
o Record dial script despite our link mode. The mode may
be changed later (next mod) :-) We never run scripts
in -direct and -dedicated modes.
o Make ``set server none'' functional again.
o Correct datalink state array so that we don't report an
``unknown'' state.
o Pass struct ipcp to IpcpCleanInterface, not struct fsm.
o Create TUN_PREFIX define rather than hard-coding in main.c
o prompt_TtyInit now handles a NULL prompt for -direct mode
rather than having to create one then destroy it uncleanly.
o Mention our mode in the "PPP Started" LogPHASE message.
o Bring all auto links up when we have something to send.
o Remove some redundant Physical_*() functions.
o Show which connection is running a command when logging
commands.
o Initialise throughput uptime correctly.
