PoPToP ChangeLog

---------------------------------------------------------------------------
v0.8.13 -> v0.9.0
11th June, 1999

- possibly fixed the 'error 629 on startup' bug.  this fix is incompatible
  with the 'silent' option of pppd, so don't use the 'silent' option.
- support a single localip with a range of remoteip's
- new, small, fast, simple get_call_id() function
- removed a few hardcoded values in ctrlpacket and replaced with defines
- new pptp_read_header() - slightly more 'expensive' but should be much more
  robust
- use openpty() if possible, internalize tty opening, startCall much more
  simple

---------------------------------------------------------------------------
v0.8.12 -> v0.8.13
10th June, 1999

- removed ctrl-manager pipe completely
- moved awareness of pppd-ip-alloc option to manager only
- if using pppd-ip-alloc, manager runs more efficiently
- made pptpctrl able to have a none, one or both of local/remote addresses
  rather than only both or none
- great code simplicication
- re-did IP parser; less potential segfaults from bad config
- correctly calculate max connections based on number of IP addresses given
  and statically configured maximum
- no max connections for the pppd-ip-alloc case
- properly permit hostnames in IP parser
- always use fd 0 for network connection
- fixed -c option
- note - this version changes the 'run from inetd' options.  re-read
  README.inetd if you use it

---------------------------------------------------------------------------
v0.8.11 -> v0.8.12
8th June, 1999

- made autoconf actually check the relevant headers
- made config.embed.h and removed most #if EMBED in favour of using this
- fixed some includes and re-arranged things to be a bit cleaner
- minor cosmetic fixes
- fixed compilation on StarOS 4 (and hence SunOS 4)
- documentation on running from ientd
- removed ctrl-manager pipe by default

---------------------------------------------------------------------------
v0.8.10 -> v0.8.11
8th June, 1999

- now only two executables, pptpd and pptpctrl
- re-did dependency generation
- minor include cleanups

---------------------------------------------------------------------------
v0.8.9 -> v0.8.10
8th June, 1999

- added getopt_long() from GNU libc for use on non-Linux platforms
- fixed compilation on FreeBSD, Digital Unix and Solaris
- replaced PPTPD_DEBUG define with configuration option (debug) and
  command line option (-d/--debug)

---------------------------------------------------------------------------
v0.8.8 -> v0.8.9
7th June, 1999

- unified CTRL and GRE processes (removed pptpgre), without the vfork
  problem since this is not forking
- changed process name for child processes to pptpd [ip.address.here]
- moved INTERNAL_IP_ALLOCATION to a configure option (see configure --help)
- added support for libwrap tcp wrappers
- made sure pppd doesn't get copies of file descriptors it shouldn't, so
  it closes down properly
- lots of other misc fixes

---------------------------------------------------------------------------
v0.8.7 -> v0.8.8
4th June, 1999

- increased MAX number of clients to 100
- layout and comments have been tidied up extensively throughout code
- new function in ctrlpacket.c for making Control Message headers
- openBSD fixes
- many other minor bug fixes
- some portability issues addressed
- accept() moved into pptpmanager.
- pptpmanager closes one side of socketpair server fd and passes client fd
    other side of socketpair to pptpctrl.
- pptpmanager main loop changed to select without timeout and made to
    watch ALL appropriate file descriptors.
- also made resiliant against some potential error modes, eg, if we are
    full don't select on new connections descriptor, if accept() fails
    ignore it cleanly, etc.
- should be more 'resource friendly' now.
- Make error state filename instead of just CONFIG FILE: file not found.
- Limit packet size to PACKET_MAX instead of permitting 4 more if no ACK
    is bundled (for consistency of packet size limit).

---------------------------------------------------------------------------
v0.8.6 -> v0.8.7
1st June, 1999

- GRE seperated from pptpctrl to support vforking
- adds link status detection (ie if a link goes down, we can figure it out
    and deal with it) (Kevin)
- Solaris/Slirp port (Harald Vogt)
- cleaned up comments a lot (move towards C style to permit compiling in 
    older compilers/increase portablity)
- standardized #ifndef #define #endif defines in header files
- stop inststr from nuking environment (hopefully)
- use longer argv[0] in exec()s to make inststr much nicer
- make inststr wipe args other than argv[0]
- #define to remove some debugging (PPTPD_DEBUG) and to remove the
    IP address allocation code so PPPD can be used to allocate IP addresses
    (INTERNAL_IP_ALLOCATION)
- in pptpctrl.c, main()'s addrlen was uninitialized - yuck, was causing
    random variable overwriting
- clean up some wasteful memory copying and so on, as well as remove some
    copies into small static buffers
- clean up some blank lines - increasing the amount of code visible one
    screen is good if it can be done without making the formatting ugly.
- use exit() not _exit() in pptpd - the fear of this closing fork()d
    filedescriptors is wrong.  both have the same file descriptor closing
    properties.
- remove a potential leak of 2 filedescriptors in option parsing (checks
    of optional file names).
- miscellaneous EMBED support for syslog etc.
- many other misc changes.

---------------------------------------------------------------------------
v0.8.5 -> v0.8.6
21st May 1999

- added new ip address reading from config file (for multiple connections)
    there is a new pptpd configuration file example in samples/
- pptpdebug.* is no longer... syslog now handles ALL debugging

---------------------------------------------------------------------------
v0.8.4 -> v0.8.5
18th May 1999

- command line args/config file options are broken (everything hardcoded)
- many, many, many structural changes for a multiple connection hack
- multiple connection support
- reconnect support
- OpenBSD port (may be broken for this release... Peter?)
- logging now to syslog DAEMON|DEBUG

---------------------------------------------------------------------------
v0.8.3 -> v0.8.4
13th May 1999

- call_id/peer_id issues addressed in OUT_CALL packets
- bug in debug log time fixed
- local added by default to the pppd launcher
- call_disconnect_notify bug fixed
- -p command line arg broken

---------------------------------------------------------------------------
v0.8.2 -> v0.8.3
11th May 1999

- a few minor multiple connection hacks.. still nowhere near ready to
    handle more than one client
- pptpd -p logfile bug fix

---------------------------------------------------------------------------
v0.8.1 -> v0.8.2
11th May 1999

- Server will no longer die if client disconnects
- pppd is closed down cleanly now
- autoconf/automake is back.. but still needs some work
- a number of minor CTRL establishment bugs fixed
- callid assignment modified slightly in manager

---------------------------------------------------------------------------
v0.8.0 -> v0.8.1
4th May 1999

- PPTPD no longer relies on a signal (which had the potential to cause
    a race condition) to know when to launch PPPD/GRE. The CTRL session
    no longer relies on a signal to return from a fork. Signalling has
    now been replaced with IPC between PPTPD and CTRL sessions.
- The GRE/PPPD sessions are now launched *after* an OUT_CALL_RPLY is sent
    not before it.
- CTRL and PPTP managers are now seperate from PPTPD

---------------------------------------------------------------------------
v0.8.0
30th April 1999

PoPToP now works with windows 95/98/NT and Linux clients.
