* Show the correct error if we fail to open a device.brian1999-06-111-7/+17

* Correct the way ppp transfers links on the server side in MPbrian1999-06-051-15/+66
| | | | | | | | | mode by padding out the ``struct device'' to the maximum device size. Bump the ppp version number to indicate the transfer format change. This should make MP over tty and udp devices functional again.
* Introduce the ``keep-session'' option. Refer to the manbrian1999-06-021-3/+6
| | | | | | page for details. This allows MP over non-tty devices where the original ppp process must not exit (such as sshd-spawned ppp sessions).

* Allow ``host:port/udp'' devices and support ``host:port/tcp'' asbrian1999-05-121-51/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | being the same as the previous (still supported) ``host:port'' syntax for tcp socket devices. A udp device uses synchronous ppp rather than async, and avoids the double-retransmit overhead that comes with ppp over tcp (it's usually a bad idea to transport IP over a reliable transport that itself is using an unreliable transport). PPP over UDP provides througput of ** 1.5Mb per second ** with all compression disabled, maxing out a PPro/200 when running ppp twice, back-to-back. This proves that PPPoE is plausable in userland.... This change adds a few more handler functions to struct device and allows derivations of struct device (which may contain their own data etc) to pass themselves through the unix domain socket for MP. ** At last **, struct physical has lost all the tty crud ! iov2physical() is now smart enough to restore the correct stack of layers so that MP servers will work again. The version number has bumped as our MP link transfer contents have changed (they now may contain a `struct device'). Don't extract the protocol twice in MP mode (resulting in protocol rejects for every MP packet). This was broken with my original layering changes. Add ``Physical'' and ``Sync'' log levels for logging the relevent raw packets and add protocol-tracking LogDEBUG stuff in various LayerPush & LayerPull functions. Assign our physical device name for incoming tcp connections by calling getpeername(). Assign our physical device name for incoming udp connections from the address retrieved by the first recvfrom().
* Revert to the previous behaviour of only doing a utmpbrian1999-05-091-2/+2
| | | | login if we're -direct on a tty device.
* o Redesign the layering mechanism and make the aliasing code part ofbrian1999-05-081-64/+676
| | | | | | | | | | | | | | | | | | | | | the layering. We now ``stack'' layers as soon as we open the device (when we figure out what we're dealing with). A static set of `dispatch' routines are also declared for dealing with incoming packets after they've been `pulled' up through the stacked layers. Physical devices are now assigned handlers based on the device type when they're opened. For the moment there are three device types; ttys, execs and tcps. o Increment version number to 2.2 o Make an entry in [uw]tmp for non-tty -direct invocations (after pap/chap authentication). o Make throughput counters quad_t's o Account for the absolute number of mbuf malloc()s and free()s in ``show mem''. o ``show modem'' becomes ``show physical''.
* Change ``set device'' so that it parses its arguments as onebrian1999-04-271-2/+3
| | | | | | | | | | device per argument rather than the old way of concatenating everything then splitting the result at commas and whitespace. Old syntax of ``set device /dev/cuaa0, /dev/cuaa1'' may no longer contain the comma, but syntax such as ``set device "!ssh host ppp -direct label"'' is now possible.
* Only call isatty() when we open our descriptor, and rememberbrian1999-01-101-7/+2
| | | | | | | | | | | the answer. If we later get a descriptor exception from select(), we know that it's a tty (isatty() returns 0 after the exception on a tty) and remember to call modem_LogicalClose(). The upshot of it all is that descriptor exceptions dont leave the tty locked any more.
* If we've got a full output buffer queue and cannot sendbrian1998-08-251-1/+11
| | | | | | | | anything for two mintues (see ``set choked'' and ``show bundle''), nuke the ip, mp and link level buffer queues. This should fix problems where ``ppp -auto'' seems to stop responding after failing to connect to the peer a few times.
* o Support callback types NONE, E.164, AUTH and CBCP.brian1998-08-071-3/+4
| | | | | | | | | | | | | | (see the new ``set callback'' and ``set cbcp'' commands) o Add a ``cbcp'' log level and mbuf type. o Don't dump core when \T is given in ``set login'' or ``set hangup''. o Allow ``*'' and blanks as placeholders in ppp.secret and allow a fifth field for specifying auth/cbcp dialback parameters. o Remove a few extraneous #includes o Define the default number of REQs (restart counter) in defs.h rather than hardcoding ``5'' all over the place. o Fix a few man page inconsistencies.
* Remove redundant includesbrian1998-06-271-3/+1

* o Move our prompt descriptor list outside of the bundle.brian1998-05-231-2/+2
| | | | | | | | | | | | | | | | | | | | It's now dealt with by the `server' object. This simplifies things as we only have one list of prompt descriptors and the log_ routines check prompt::logactive to determine whether it should be used for output. o Include the MP socket UpdateSet() result in bundle::UpdateSet(). o Don't select on the tun device unless we're in NETWORK phase or AUTO mode. o Stop the idle timer when we go to DEAD phase. We may have transferred a link and not had a chance to kill it. o Don't fail when trying to unlink our transferred datalink from our descriptor lists just before the transfer. o Add our link descriptor to the write set if we got a short write the last time (physical::out is set). o Log the connection source address when a connection is closed. o Remove descriptor::next field. Descriptor lists are not required any more.
* MFMP: Make ppp multilink capable.brian1998-05-211-0/+230
