dd0645c5b7 o Add the `set mode' command for change a links current mode. It
is not possible to switch to or from dedicated or direct mode,
  but all other combinations are ok (eg. -auto -> -ddial).
o Cope with the fact that commands with optional context may not
  be able to obtain a link with command_ChooseLink() (if all links
  have been deleted for example).
o Allow `clone'ing in non-multilink mode.  We may for example want
  to configure two links in unilink mode and dial them both, using
  the one that comes up first.  It's also possible to rename
  ``deflink'' by cloning it, deleting the original, then setting
  the mode of the new link.

610b185f37 Create `struct sticky_route'.
Any `add' or `delete' command that uses MYADDR or HISADDR
will be added to the sticky route list (show ipcp).  When
MYADDR or HISADDR change due to IPCP negotiations, and if
`sroutes' is enabled (the default), all sticky route
entries are updated in the routing table.

The end result is that `add default hisaddr' will ``stick'',
as will ``add myaddr 255.255.255.255 127.0.0.1'' and
``add 1.2.3.4 255.255.255.0 hisaddr''.

ce828a6ecc o Add ipcp_SetLink() for attaching IPCP to the correct link, and
call it after link authentication.
o Pretty print our bundle MTU.
o Correct MP header encoding and decoding (should be network byte order).
o Add some debug diagnostics so that we can see MP fragment sending and
  re-assembly.

3edeb0c69e Support client side DNS server negotiation, disabled
and denied by default (POLA).

o Remove ``enable'' msext.  Now, doing a ``set nbns'' will
  automatically enable a NBNS ACK/NAK rather than a REJ.
o Add accept|disable|deny|enable dns.  If we ``accept'',
  we'll tell the peer what our nameservers are (if he asks).
  The values in resolv.conf can be overridden with the
  ``set dns'' command.  If we ``enable'', we'll REQ using
  our resolv.conf entries, and any NAKs are written back to
  resolv.conf.
o Remove ``show msext'' and show the relevent IP numbers in
  ``show ipcp''.
1998-04-17 22:05:37 +00:00

1342caed9c o Move the accept/deny/disable/enable globals either to the
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.

565e35e50e o Remove the `mode' global - it's now per physical device.
o Shuffle things that live at the datalink level into
  ``show link'' rather than ``show modem''.
o Make both ``show'' commands prettier and more consistent,
  and display carrier status, link type and our name in
  ``show modem''.
o Show redial and reconnect information in ``show link''
  and remove ``show redial'' and ``show reconnect''.
o Down the correct link in bundle_LinkLost().
o Remove stale -direct and -background links at the end
  of our main loop, not when we know they're going.  This
  prevents unexpected pointer-invalidations...
o If we ``set server'' with the same values twice, notice
  and don't moan about failure.
o Record dial script despite our link mode.  The mode may
  be changed later (next mod) :-)  We never run scripts
  in -direct and -dedicated modes.
o Make ``set server none'' functional again.
o Correct datalink state array so that we don't report an
  ``unknown'' state.
o Pass struct ipcp to IpcpCleanInterface, not struct fsm.
o Create TUN_PREFIX define rather than hard-coding in main.c
o prompt_TtyInit now handles a NULL prompt for -direct mode
  rather than having to create one then destroy it uncleanly.
o Mention our mode in the "PPP Started" LogPHASE message.
o Bring all auto links up when we have something to send.
o Remove some redundant Physical_*() functions.
o Show which connection is running a command when logging
  commands.
o Initialise throughput uptime correctly.

2764b86afd o Move alias function pointers into loadalias.c
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.

a3e274968f int var : 1' -> unsigned var : 1'.
This made things look silly and made us mis-negotiate the
number of VJ slots.
1998-04-05 19:02:49 +00:00
Brian Somers
cd9647a100 o Move default MRU, MTU, ACCMAP and OPENMODE config values into
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.

6d6667755e Create struct fsm_parent. FSMs are created with one of these,
and the FSM passes subsequent events to them.

503a7782d8 Shuffle around our FSMs a bit. This'll make it

globals.

68a0f0ccdd o Add bundle_Destroy().
o Don't remove routes and DOWN the interface when we're
  closed in auto mode.
o Initialize the FSMs in bundle_Create.
o Initialize ipcp::if_mine & ipcp::if_peer only once (so
  that we don't forget that we've SIOCAIFADDR'd the interface).
o Do a SIOCDIFADDR on the specific address to avoid hurting any
  other (still non-existent) NCPs.
o Fix some error/diagnostic messages.

aad81d1ecf Rename ccpstate to ccp, ipcpstate to ipcp and lcpstate to lcp. 1998-02-08 11:05:01 +00:00
Brian Somers
455aabc3f8 o Hook the FSMs into our bundle.
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.

7a6f872047 Create `struct bundle' - the top level control structure.
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.

7308ec6890 Move the global FSMs into their relevent structures.
IPCP, CCP and LCP are now just derived FSMs.
Comment each of the FSM implementations so that we can
tell what's going on.
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).

o Allow a forth argument in ppp.secret, specifying a new
  label.  This gives control over which section of
  ppp.link{up,down} is used based on the authenticated user.
o Support random address ranges in ppp.secret (not just in ppp.conf).
o Add a AUTHENTICATING INCOMING CONNECTIONS section to the man page.
o Add a bit more about DEFLATE in the man page.
o Fix the incorrect "you must specify a password in interactive
  mode" bit of the manual.
o Space things in the man page consistently.
o Be more precice about where you can use MYADDR, HISADDR and INTERFACE
  in the "add" command documentation.

bcc332bdb0 Allow random IP number allocation to peer.
Validate the peers suggested IP by attempting to make a routing table
entry.
Give up IPCP negotiation if the peer NAKs us with an unusable IP.
Always SIOCDIFADDR then SIOCAIFADDR when configuring the tun device.
Using SIOCSIFDSTADDR allows duplicate dst addresses (which we don't
want)!!!
Allow up to 200 interface names (was 50) (now that ppp can play server
properly).
Up the version number (1.5 -> 1.6).

Cosmetic:
  Log unexpected CCP packets in the CCP log rather than the ERROR log.
  Log unexpected Config Reqs in the appropriate LCP/IPCP/CCP log rather
  than the ERROR log.
  Log failed route additions and deletions with WARN, not TCPIP.
  Log the option id and length for unrecognised IPCP options.
  Change some .Sq to .Ar in the man page.

  -Winline -Wmissing-declarations -Wmissing-prototypes
  -Wnested-externs -Wpointer-arith -Wredundant-decls

927145be97 Overhaul ppp:
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.

   o Fixing bug for Predictor-1 function.
   o Add new parameter that re-sent interval for set timeout commands.
   o Improving RTT (Round Trip Time) and reducing processor time.
     - Previous Timer service was using polling, and now using
       SIGALRM ;-)
     - A 0.94beta2 will not work correctly....

   -- Follows are additinal feature not including 0.94beta2
   o Support Proxy ARP
     - add "enable/disable proxy" commands
   o Marging common routine in CHAP/PAP.
   o Enhancing LCP/IPCP log information.
   o Support local Authfication connection on port 300x and tty.
     - You can set up pair of your "hostname -s" and
       password in ppp.secret. if either ppp.secret file nor
       your hostname line don't exist, It will notify a message
       and working as same as previous version.(Backword compatibility)
     - If you did set up them, It's allow connection but nothing to do
       except help and passwd command.
     - add "passwd yourpasswd" commands
   o Support afilter - keep Alive filter that a packet can send/receiving
     according to ifilter/ofilter but doesn't count it as preventing idle
     timer expires.
     - Same syntax of other filters.
   o Fixing bugs reported by current user for previous one. Thanks !!
