secnet (0.4.0~beta2~) unstable; urgency=low

  * polypath: Ignore IPv6 Unique Local unicast addresses.

 --

secnet (0.4.0~beta1) unstable; urgency=low

  New features:
  * Support transport over IPv6.  (We do not yet carry IPv6 in the private
    network.)  IPv6 support depends on IPv6-capable adns (adns 1.5.x).
  * New polypath comm, which can duplicate packets so as to send them via
    multiple routes over the public network, for increased
    reliability/performance (but increased cost).  Currently Linux-only
    but should be fairly easy to port.
  * Support multiple public addresses for peers.
  * Discard previously-received packets (by default).

  Logging improvements:
  * Report (each first) transmission and reception success and failure.
  * Log reason for DNS reolution failure.
  * Log unexpected kinds of death from userv.
  * Log authbind exit status as errno value (if appropriate).

  Configuration adjustments:
  * Adjust default number of mobile peer addresses to store when a peer
    public address is also configured.
  * Make specifying peer public port optional.  This avoids making special
    arrangements to bind to a port for in mobile sites with no public
    stable address.

  Bugfixes:
  * Hackypar children will die if they get a terminating signal.
  * Fix signal dispositions inherited by secnet's child processes.
  * Fix off-by-one error which prevented setting transport-peers-max to 5.

  Test, build and internal improvements:
  * Use conventional IP address handling library ipaddr.py.
  * Provide a fuzzer for the slip decoder.
  * Build system improvements.
  * Many source code cleanups.

secnet (0.3.4) unstable; urgency=low

  SECURITY FIX:
  * The previous security fix to buffer handling was entirely wrong.  This
    one is better.  Thanks to Simon Tatham for the report and the patch.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Mon, 22 Sep 2014 16:16:11 +0100

secnet (0.3.3) unstable; urgency=high

  SECURITY FIXES:
  * Pass correct size argument to recvfrom.  This is a serious security
    problem which may be exploitable from outside the VPN.
  * Fix a memory leak in some error logging.

  Other related fixes:
  * Two other latent bugs in buffer length handling found and fixed.
  * Non-critical stylistic improvements to buffer length handling, to make
    the code clearer and to assist audit.

secnet (0.3.3~beta1) unstable; urgency=low

  Installation compatibility fix:
  * In make-secnet-sites, always use our own ipaddr.py even if the
    incompatible modern ipaddr.py is installed (eg via python-ipaddr.deb).
    (Future versions of secnet are going to need that Python module to be
    installed.)

  For links involving mobile sites:
  * Use source of NAK packets as hint for peer transport address.
  * When initiating rekey, make use of data transport peer addresses.

  Build fix:
  * Provide clean target in test-example/Makefile.

secnet (0.3.2) unstable; urgency=low

  * Release of 0.3.2.  No code changes since 0.3.1~beta1.

 -- Ian Jackson <ijackson@chiark.greenend.org.uk>  Thu, 26 Jun 2014 20:27:58 +0100

secnet (0.3.2~beta1) unstable; urgency=low

  For links involving mobile sites:
  * SECURITY: Properly update peer address array when it is full.
  * Do name-resolution on peer-initiated key setup too, when we are mobile
    (and other name-resolution improvements).

  Other minor improvements:
  * Log peer addresses on key exchange timeout.
  * When printing version (eg during startup), use value from git-describe
    and thus include git commit id where applicable.
  * Updates to release checklist in Makefile.in.
  * Use C99 _Bool for bool_t.

secnet (0.3.1~beta1) unstable; urgency=low

  Security fixes (vulnerabilities are to inside attackers only):
  * SECURITY: Fixes to MTU and fragmentation handling.
  * SECURITY: Correctly set "unused" ICMP header field.

  * Make the inter-site MTU configurable, and negotiate it with the peer.

  Bugfixes etc.:
  * Fix netlink SEGV on clientless netlinks (i.e. configuration error).
  * Fix formatting error in p-t-p startup message.
  * Do not send ICMP errors in response to unknown incoming ICMP.
  * Fix formatting error in secnet.8 manpage.
  * Internal code rearrangements and improvements.

  Packaging improvements:
  * Updates to release checklist in Makefile.in.
  * Additions to the test-example suite.
