* 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.

It *should* now be possible to build ppp with -DNODES and still support CHAP/MSCHAP/MSCHAPv2/MPPE via a RADIUS server, but the code isn't yet smart enough to do that (building with -DNODES just looses these facilities).

The changes are cosmetic except: RecvConfigAck() now displays the options that are being ACK'd Huge (bogus) options sent from the peer won't cause an infinite loop SendIdent and ReceiveIdent are displayed consistenlty with other FSM data LCP AUTHPROTO options that aren't understood are NAK'd, not REJ'd Notes: svn path=/head/; revision=94894
* Reduce the interface MTU by 2 when MPPE has been successfully negotiated.Brian Somers2001-07-031-0/+1
| | | | | | | | | This is necessary because MPPE will combine the protocol id with the payload received on the tun interface, encrypt it, then prepend its own protocol id, effectively increasing the payload by two bytes. Notes: svn path=/head/; revision=79165
* Add support for stateful MPPE (microsoft encryption) providingBrian Somers2001-06-181-4/+11
| | | | | | | | | | | | | | | | | | encryption compatibility with Windows 2000. Stateful encryption uses less CPU but is bad on lossy transports. The ``set mppe'' command has been expanded. If it's used with any arguments, ppp will insist on encryption, closing LCP if the other end refuses. Unfortunately, Microsoft have abused the CCP reset request so that receiving a reset request does not result in a reset ack when using MPPE...

* Add a ``Usable'' function to the ccp switch. The functionBrian Somers2001-02-041-0/+1
| | | | | | | | | | | | | | | | is called prior to sending a CCP configure request for a given protocol. The default is to send the request, but this is overridden for MPPE which checks to see if the lcp negotiations agreed CHAP81, and if not fails. Use the same function to decide if we should reject peer requests for MPPE. This should get rid of those boring messages about not being able to initialise MPPE when we don't negotiate CHAP81.

It was showing mbuf stats twice on receipt of LCP/CCP/IPCP packets.... ???!!? o Pre-allocate a bit extra when creating LQR packets to avoid having to allocate another mbuf in mbuf_Prepend().

* Deal with the fact that as we now mbuf_Read the fsmBrian Somers1999-05-091-2/+2

* o Redesign the layering mechanism and make the aliasing code part ofBrian Somers1999-05-081-9/+11
| | | | | | | | | | | | | | | | | | | | | | | | 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''.

* Tone down the log levels (Log{ERROR,WARN} -> LogCCP)Brian Somers1999-03-111-5/+7
| | | | | | | | | | | | | | | when we've simply missed a packet. When our Predictor1 CRC is wrong (implying we've dropped a packet), don't send a ResetReq(). Instead, send another CCP ConfigReq(). *shrug* My tests show this as being far worse than the ResetReq as we may have further Nak/Rejs etc and we're basically resetting both our incoming and outgoing compression dictionaries, but rfc1978 says the ConfigReq is correct, so we'd better go along... Notes: svn path=/head/; revision=44650

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.

| * o Remove the global CcpInfo. It's now part of the datalink.Brian Somers1998-02-231-12/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/cvs2svn/branches/MP/; revision=33754

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).

It's now controlled with "set log +debug" o Add "set log command, debug, tun, warn, error, alert" o Remove cdefs.h, and assume an ansi compiler. o Improve all diagnostic output o Don't trap SIGSEGV o SIGHUP now terminates again (log files are controlled by syslog) o Call CloseModem() when changing devices o Fix parsing of third arg of "delete" I think this fixes the "magic is same" problems that some people have been experiencing.

* Here is a diff of /usr/src/usr.sbin/ppp against current. The diffsPoul-Henning Kamp1996-05-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | add some logging functionality which I find very useful. 'set debug link' will record just link up/down and address assignments. 'set debug connect' will record the entire chat dialog 'set debug carrier' will record just chat lines including 'CARRIER' (so that I can be sure I'm getting a 28.8 line). There was a global change required to permit LogPrintf to take a bit mask instead of a bit position value (to permit logging some events on either of two flags, so that no change in 'set debug lcp' would result from the code supporting 'link'. Thus the diffs are rather long for such a small change. The man page is also touched. Oh, and there was a slight syntax problem in route.c Reviewed by: phk Submitted by: Tony Kimball <alk@Think.COM> Notes: svn path=/head/; revision=15738
* Some patches to ppp which improve stability. I have been running aDoug Rabson1996-01-301-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ppp based on these patches for about 3 weeks with no downtime. The original submitters comments: Two features iijppp has over kernel ppp that I like are predictor1 compression and demand dialing. Here are a few bug fixes. I expanded the priority queueing scheme and discovered it was broken due to the assignment at ip.c line 300. All packets were being queued at the same priority. Fixing priority queueing broke predictor1 compression. Packets were compressed before being queued and predictor1 worked as long as the packets were popped off the queue in the same order they were pushed onto the queue. There were a few byte order problems in IP header tests also. There is a recursion problem in SendLqrReport(). LcpClose() is called when "Too many echo packets are lost" which winds up in SendLqrReport() again. I believe the original intention was to just stop the LQR timer with the call to StopLqr() but the side effects hurt. Submitted by: John Capo <jc@irbs.com> Notes: svn path=/head/; revision=13733
