* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

| | | | | | | | | | | | | | | | | | | | | o Bump version number to 3.0.4 o When talking to a RADIUS server, provide a NAS-Port-Type. When the NAS-Port-Type is Ethernet, provide a NAS-Port value equal to the SESSIONID from the environment in direct mode or the NGM_PPPOE_SESSIONID message in other modes. If no SESSIONID is found, default to the interface index in client mode or zero in server mode. When the NAS-Port-Type is ISDN, set the NAS-Port to the minor number of the physical device (ie, the N in /dev/i4brbchN). This makes it easier for the RADIUS server to identify the client WRT accounting data etc. Prompted by: lsz8425 <lsz8425@mail.cd.hn.cn> Notes: svn path=/head/; revision=96582

It's now possible to manage IPv6 interface addresses and routing table entries and to filter IPV6 traffic whether encapsulated or not. IPV6CP support is crude for now, and hasn't been tested against any other implementations. RADIUS and IPv6 are independent of eachother for now. ppp.linkup/ppp.linkdown aren't currently used by IPV6CP o Understand all protocols(5) in filter rules rather than only a select few. o Allow a mask specification for the ``delete'' command.

* Rewrite the link descriptor transfer code in MP mode.Brian Somers1999-11-251-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, ppp attempted to bind() to a local domain tcp socket based on the peer authname & enddisc. If it succeeded, it listen()ed and became MP server. If it failed, it connect()ed and became MP client. The server then select()ed on the descriptor, accept()ed it and wrote its pid to it then read the link data & link file descriptor, and finally sent an ack (``!''). The client would read() the server pid, transfer the link lock to that pid, send the link data & descriptor and read the ack. It would then close the descriptor and clean up. There was a race between the bind() and listen() where someone could attempt to connect() and fail. This change removes the race. Now ppp makes the RCVBUF big enough on a socket descriptor and attempts to bind() to a local domain *udp* socket (same name as before). If it succeeds, it becomes MP server. If it fails, it sets the SNDBUF and connect()s, becoming MP client. The server select()s on the descriptor and recvmsg()s the message, insisting on at least two descriptors (plus the link data). It uses the second descriptor to write() its pid then read()s an ack (``!''). The client creates a socketpair() and sendmsg()s the link data, link descriptor and one of the socketpair descriptors. It then read()s the server pid from the other socketpair descriptor, transfers any locks and write()s an ack. Now, there can be no race, and a connect() failure indicates a stale socket file. This also fixes MP ppp over ethernet, where the struct msghdr was being misconstructed when transferring the control socket descriptor. Also, if we fail to send the link, don't hang around in a ``session owner'' state, just do the setsid() and fork() if it's required to disown a tty.

* Add ISDN support via isdnd & i4b. This requires versionBrian Somers1999-08-061-6/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 0.81.1 of the i4b code - namely support of the I4B_VR_REQ ioctl via the i4brbchX device. Ppp controls the phone number, but idle timers and SYNC/RAW decisions are still made by isdnd (in isdnd.rc). This involves a new datalink state machine phase. The ``wait for carrier'' phase happens after dialing but before logging in. The whole dial state should really be abstracted so that each device type can deal with it in its own way (thinking about PPPoE) - but that'll have to wait. The ``set cd'' symantics remain the same for tty devices, but we now delay until we either get CD or timeout waiting (at which time we drop the link if we require CD). For i4b devices we always insist on carrier. Thanks to hm@ for his help, and especially for pointing out that I *don't* need to re-implement isdnd (that was a huge waste of time !) :-] Notes: svn path=/head/; revision=49472
* o Obsolete the undocumented ``set weight'' command.Brian Somers1999-08-051-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | o If we're using RADIUS and the RADIUS mtu is less than our peers mru/mrru, reduce our mtu to this value for NetBSD too. o Make struct throughput's sample period dynamic and tweak the ppp version number to reflect the extra stuff being passed through the local domain socket as a result (MP mode). o Measure the current throughput based on the number of samples actually taken rather than on the full sample period. o Keep the throughput statisics persistent while being passed to another ppp invocation through the local domain socket. o When showing throughput statistics after the timer has stopped, use the stopped time for overall calculations, not the current time. Also show the stopped time and how long the current throughput has been sampled for. o Use time() consistently in throughput.c o Tighten up the ``show bundle'' output. o Introduce the ``set bandwidth'' command. o Rewrite the ``set autoload'' command. It now takes three arguments and works based on a rolling bundle throughput average compared against the theoretical bundle bandwidth over a given period (read: it's now functional).

* Allow ``host:port/udp'' devices and support ``host:port/tcp'' asBrian Somers1999-05-121-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

* o Redesign the layering mechanism and make the aliasing code part ofBrian Somers1999-05-081-19/+19
| | | | | | | | | | | | | | | | | | | | | | | | 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 the non-convergence thresholds to 3 times the number of configured REQ tries (rather than the previous fixed ``10''). We now notice repeated NAKs and REJs rather than just REQs. Don't suggest that CHAP 0x05 isn't supported when it's not configured. Fix some bugs that expose themselves with smaller numbers of retries: o Handle instantaneous disconnects (set device /dev/null) correctly by stopping all fsm timers in fsm2initial. o Don't forget to uu_unlock() devices that are files but are not ttys (set device /dev/zero). Fix a *HORRENDOUS* bug in RFC1661 (already fixed for an Open event in state ``Closed''): According to the state transition table, a RCR+ or RCR- received in the ``Stopped'' state are supposed to InitRestartCounter, SendConfigReq and SendConfig{Ack,Nak}. However, in ``Stopped'', we haven't yet done a TLS (or the last thing we did is a TLF). We must therefore do the TLS at this point ! This was never noticed before because LCP and CCP used not use LayerStart() for anything interesting, and IPCP tends to go into Stopped then get a Down because of an LCP RTR rather than getting a RCR again.

| | | | | | | | | | | | | | | | | | | | | | each time rather than making up a new one. Increase the authname/authkey max sizes to 100 characters. Allow ``authkey'' specifications beginning with ``!''. When a challenge is received, the text following the ``!'' is executed as a program (expanding stuff in the same way that ``sh'' and ``!bg'' do). The program is passed the peer name, peer challenge and local ``authname'' on standard input and is expected to output the name/key combination that should be used to build the CHAP response. This provides support for Secure ID cards (guess what I was given at work recently!) using CHAP. Examples will follow. Notes: svn path=/head/; revision=43888
* Decouple pap & chap output routines from the correspondingBrian Somers1999-02-061-25/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | input routines and take advantage of the new init/continue interface in libradius. This allows a timely response on other links in an MP setup while RADIUS requests are in progress as well as the ability to handle other data from the peer in parallel. It should also make the future addition of PAM support trivial. While I'm in there, validate pap & chap header IDs if ``idcheck'' is enabled (the default) for other FSM packet types. NOTE: This involved integrating the generation of chap challenges and the validation of chap responses (and commenting what's going on in those routines). I currently have no way of testing ppps ability to respond to M$Chap CHALLENGEs correctly, so if someone could do the honours, it'd be much appreciated (it *looks* ok!).
