* Understand the following Microsoft Vendor Specific RADIUS attributes:brian2002-06-121-4/+6
| | | | | | | | | | | | | | | | | RAD_MICROSOFT_MS_MPPE_ENCRYPTION_POLICY RAD_MICROSOFT_MS_MPPE_ENCRYPTION_TYPES RAD_MICROSOFT_MS_MPPE_RECV_KEY RAD_MICROSOFT_MS_MPPE_SEND_KEY These attributes may be supplied by a RADIUS server when MSCHAPv2 is used to authenticate. 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).

* Make the way FSM options are processed easier to read by using structuresbrian2002-04-161-20/+10
| | | | | | | | | | | instead of u_char *. 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
* Reduce the interface MTU by 2 when MPPE has been successfully negotiated.brian2001-07-031-0/+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.
* Add support for stateful MPPE (microsoft encryption) providingbrian2001-06-181-4/+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 functionbrian2001-02-041-0/+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.

* o Alter the mbuf type as it's processed by different layers.brian1999-06-021-3/+3
| | | | | | | | o Show more information about missing MP fragments in ``show mp''. o Do away with mbuf_Log(). 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 fsmbrian1999-05-091-2/+2
| | | | | | | | | header in fsm_Input() we often end up with a NULL mbuf. Deal with a possible NULL mbuf being passed into mbuf_Prepend(). Adjust some spacing to make things more consistent.
* o Redesign the layering mechanism and make the aliasing code part ofbrian1999-05-081-9/+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''.
* Detect pred1 packets where the length != the packet lengthbrian1999-03-161-12/+17
| | | | | | Use a maximum of MAX_MRU + 2 bytes for incoming packets, not MAX_MTU + 2. Tidy up some diagnostics.
* Tone down the log levels (Log{ERROR,WARN} -> LogCCP)brian1999-03-111-5/+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...
* o Support callback types NONE, E.164, AUTH and CBCP.brian1998-08-071-1/+2
| | | | | | | | | | | | | | (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 extraneous decls. Add ``const'' to several places. Allow ``make NOALIAS=1'' to remove IP aliasing. Merge with OpenBSD - only the Makefiles vary. We can now survive a compile with -Wall -Wbad-function-cast -Wcast-align -Wcast-qual -Winline -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wredundant-decls -Wshadow -Wstrict-prototypes -Wwrite-strings -Wchar-subscripts (although the Makefile just contains -Wall).
* Introduce ID0 logging.brian1997-11-091-1/+2
| | | | | | | | Stay as the invoking uid as much as possible. Execution as a normal user is still forbidden for now, so these changes are pretty ineffective. The next commit will implement the modifications suggested on -hackers a number of days ago.
* Cosmetic (no functional changes):brian1997-10-261-11/+21
| | | | | | | | | | | | | | | o Add missing $Id$s o Move extern decls from .c -> .h files o Staticize o Remove #includes from .h files o style(9)ify includes o bcopy -> memcpy bzero -> memset bcmp -> memcmp index -> strchr rindex -> strrchr o Move timeout.h -> timer.h (making it consistent w/ timer.c) o Add -Wmissing-prototypes
* Make the code format more in line with style(9).brian1997-08-251-74/+66
| | | | | Update loadalias to use the new libalias api. Update to version 1.1.
* Make the man page a little more detailed.brian1997-06-091-3/+3
| | | | | Update the version number to 1.00. Increase the predictor-1 buffer by 2 bytes.
* Overhaul ppp:brian1997-06-091-10/+7
| | | | | | | | | | | | | | | | | | | | | | | | | o Use syslog o Remove references to stdout/stderr (incl perror()) o Introduce VarTerm - the interactive terminal or zero o Allow "set timeout" to affect current session o Change "set debug" to "set log" o Allow "set log [+|-]flag" o Make MSEXT and PASSWDAUTH stuff the default o Move all #ifdef DEBUG stuff into the code - this shouldn't be too much overhead. 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. The man page is being rewritten. It'll follow soon.

| | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

* Here is a diff of /usr/src/usr.sbin/ppp against current. The diffsphk1996-05-111-2/+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>
* Some patches to ppp which improve stability. I have been running adfr1996-01-301-3/+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>
