* spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSDWarner Losh2023-05-121-1/+1
| | | | | | | | | The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix
* 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.

* Add a ``log'' command for logging specific information.Brian Somers2001-11-031-0/+1
| | | | | | | | | | | | | | | | | Add an ``UPTIME'' variable to indicate the bundle uptime. It's now possible to put something like this in ppp.linkdown for a server setup: MYADDR: log Session closing: User USER, address HISADDR, up UPTIME Fixed some memory leakage with commands that expand words. Made some functions static. Fixed a diagnostic bug (iface add .... SIOCDIFADDR) Notes: svn path=/head/; revision=85991

* When resending chap challenges, resend the same challengeBrian Somers1999-02-111-1/+3
| | | | | | | | | | | | | | | | | | | | | | 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

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.... Notes: svn path=/cvs2svn/branches/MP/; revision=35568

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/cvs2svn/branches/MP/; revision=35219
| * Pass all command arguments around with struct cmdargs ratherBrian Somers1998-04-141-1/+2
| | | | | | | | | | | | | | | | | | than incrementing argv and decrementing argc. Now individual functions can determine their caller. This also removes the "prefix" hack in FindExec(). Notes: svn path=/cvs2svn/branches/MP/; revision=35200
| * o Move alias function pointers into loadalias.cBrian Somers1998-04-071-4/+4
| | | | | | | | | | | | | | | | | | | | | | o Move Var*Version into command.c o Remove struct pppVars (and there was much rejoicing) ! o Forward-decl some structs in .h files to avoid include ordering requirements and remove a few more redundant #includes. Notes: svn path=/cvs2svn/branches/MP/; revision=35089
| * Deglobalise `struct prompt':Brian Somers1998-04-031-8/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Our diagnostic socket has its password set in the `set socket' line only (not in ppp.secret). o Passwords are per server socket (*VarAuthKey are gone) o Authority is per prompt (VarLocalAuth is gone). o Local logging is per prompt. o Add a `show who' command to see who's connected. No identd routine - just a `where the connection came from' display. o SIGUSR1 is disabled for now - we have no way of choosing a password for the socket created :-( Prompts are attached as a list of `struct descriptor's in struct bundle, and serviced under the bundles descriptor service routines. Ultimately, everything should be done like this. Cosmetic: o alphabeticalise SRCS in Makefile. o Add a few comments in command.h TODO: Start checking that we don't overflow the descriptor sets in select() now that we can have any number of descriptors. Notes: svn path=/cvs2svn/branches/MP/; revision=35016
| * o Move default MRU, MTU, ACCMAP and OPENMODE config values intoBrian Somers1998-04-031-6/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | struct lcp and display them in `show lcp'. o Remove `show mru' and `show mtu' and make the data part of `show lcp'. Also merge `set m[tr]u' and `set openmode' implementations into the SetVariable function. o `set timeout' only accepts the idle timer value as an argument. o Move our lqr period into struct lcp, and create a `set lqrperiod' command. Display it in `show lcp'. o Remove VarRetryTimeout, and implement it at the LCP, PAP, CHAP, CCP and IPCP levels, creating individual `set XXXretry' commands for each. They must be separate because they have different context requirements in multilink mode. o Display default config values in `show ccp'. o Tart the man page up a bit (wrt PPP/TCP, compression and LQR) and explain the new commands. Notes: svn path=/cvs2svn/branches/MP/; revision=35010
| * o Move struct lcp and struct ccp into struct link.Brian Somers1998-04-031-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Remove bundle2lcp(), bundle2ccp() and bundle2link(). They're too resource-hungry and we have `owner pointers' to do their job. o Make our FSM understand LCPs that are always ST_OPENED (with a minimum code that != 1). o Send FSM code rejects for invalid codes. o Make our bundle fsm_parent deal with multiple links. o Make timer diagnostics pretty and allow access via ~t in `term' mode (not just when logging debug) and `show timers'. Only show timers every second in debug mode, otherwise we get too many diagnostics to be useful (we probably still do). Also, don't restrict ~m in term mode to depend on debug logging. o Rationalise our bundles' phases. o Create struct mp (multilink protocol). This is both an NCP and a type of struct link. It feeds off other NCPs for output, passing fragmented packets into the queues of available datalinks. It also gets PROTO_MP input, reassembles the fragments into ppp frames, and passes them back to the HDLC layer that the fragments were passed from. ** It's not yet possible to enter multilink mode :-( ** o Add `set weight' (requires context) for deciding on a links weighting in multilink mode. Weighting is simplistic (and probably badly implemented) for now. o Remove the function pointers in struct link. They ended up only applying to physical links. o Configure our tun device with an MTU equal to the MRU from struct mp's LCP and a speed equal to the sum of our link speeds. o `show {lcp,ccp,proto}' and `set deflate' now have optional context and use ChooseLink() to decide on which `struct link' to use. This allows behaviour as before when in non-multilink mode, and allows access to the MP logical link in multilink mode. o Ignore reconnect and redial values when in -direct mode and when cleaning up. Always redial when in -ddial or -dedicated mode (unless cleaning up). o Tell our links to `staydown' when we close them due to a signal. o Remove remaining `#ifdef SIGALRM's (ppp doesn't function without alarms). o Don't bother strdup()ing our physical link name. o Various other cosmetic changes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o The FSM layering is now more sane. o Move a lot of the NCP stuff into our ipcpstate rather than having it in the bundle, including control of the configured IP addresses. We don't need hacks like the global `linkup' variable any more as the FSM decides when our ppp.link* files get run. This is going to eventually be configurable based on FSM events anyway. o Fix a few inconsistencies when both sides require authentication. o We now have "Ppp..." and "PPp" prompts, reflecting authentication and network phase. We don't print loads of spurious prompts as we change phases any more. o Our phase is part of the bundle now. o Fix a bug where the FSM wasn't calling LayerFinish. o Close the FSM down correctly with a signal rather than slamming it down as if the line was dropped (the undocumented ``down'' command is still available though). o Remove the forgotten `tunno' variable and fix references to it. Notes: svn path=/cvs2svn/branches/MP/; revision=33162
| * Create `struct bundle' - the top level control structure.Brian Somers1998-02-021-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | This structure will eventually contain a list of NCPs (currently only IPCP is supported) and a list of physical `struct link's. It will also derive from a struct link itself. Make ModemTimeout() static - it's way to dangerous to be called from outside ! Bump version to 1.9. Our first MP release should be 2.0.

* Fix prototypes.Brian Somers1997-11-221-9/+18
| | | | | | | | | | | | | | | | | 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).

* Finish the security improvements:Brian Somers1997-11-111-1/+3
| | | | | | | | | | | | | | | | | | | | | | o Add "allow" command: "allow users a b c" gives access to users a, b and c. "allow modes auto" gives those users access to auto mode only. "allow users *" and "allow modes *" are accepted. No users and all modes are allowed by default. UID 0 can do anything. o Set the current label with the "load" and "dial" commands so that the call to ppp.linkdown makes sense. o Up the verison number. o Don't OR MODE_AUTO for -background and -ddial. o Don't OR MODE_INTER when we get a diagnostic connection. o Allow up to 40 args per line (was 20). o "set ifaddr" only changes the interface in AUTO mode (with other modes, it happens after IPCP negotiation). o Sort command descriptions in the man page. o Support -dedicated mode where we just talk ppp forever (no login etc).
