secnet (0.4.0~~iwj~) UNRELEASED; 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. -- Ian Jackson Thu, 09 Oct 2014 19:19:05 +0100 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 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. -- Ian Jackson Fri, 19 Sep 2014 23:50:45 +0100 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. -- Ian Jackson Fri, 19 Sep 2014 00:11:44 +0100 secnet (0.3.2) unstable; urgency=low * Release of 0.3.2. No code changes since 0.3.1~beta1. -- Ian Jackson 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. -- Ian Jackson Fri, 06 Jun 2014 01:17:54 +0100 secnet (0.3.1) unstable; urgency=low * Release of 0.3.1. No code changes since 0.3.1~beta3. -- Ian Jackson Thu, 15 May 2014 01:08:30 +0100 secnet (0.3.1~beta3) unstable; urgency=low * Build fixes for non-i386 architectures and gcc 4.8.2. -- Ian Jackson Thu, 08 May 2014 19:53:43 +0100 secnet (0.3.1~beta2) unstable; urgency=low Fix relating to new fragmentation / ICMP functionality: * Generate ICMP packets correctly in point-to-point configurations. -- Ian Jackson Sat, 03 May 2014 18:58:09 +0100 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. * SECURITY: Fix IP length check not to crash on very short packets. New feature: * 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. -- Ian Jackson Thu, 01 May 2014 19:02:56 +0100 secnet (0.3.0) unstable; urgency=low * Release of 0.3.0. No code changes since 0.3.0~beta3. * Update release checklist. -- Ian Jackson Sun, 01 Sep 2013 20:27:48 +0100 secnet (0.3.0~beta3) unstable; urgency=low * New upstream version. - Stability bugfix: properly initialise site's scratch buffer. -- Ian Jackson Mon, 05 Aug 2013 11:54:09 +0100 secnet (0.3.0~beta2) unstable; urgency=low * New upstream version. - SECURITY FIX: RSA public modulus and exponent buffer overflow. - SECURITY FIX: Use constant-time memcmp for message authentication. - SECURITY FIX: Provide a new transform, eax-serpent, to replace cbcmac. - SECURITY FIX: No longer send NAKs for NAKs, avoiding NAK storm. - SECURITY FIX: Fix site name checking when site name A is prefix of B. - SECURITY FIX: Safely reject too-short IP packets. - Better robustness for mobile sites (proper user of NAKs, new PROD msg). - Better robustness against SLIP decoding errors. - Fix bugs which caused routes to sometimes not be advertised. - Protocol capability negotiation mechanism. - Improvements and fixes to protocol and usage documentation. - Other bugfixes and code tidying up. -- Ian Jackson Thu, 25 Jul 2013 18:26:01 +0100 secnet (0.3.0~beta1) unstable; urgency=low * New upstream version. - SECURITY FIX: avoid crashes (or buffer overrun) on short packets. - Bugfixes relating to packet loss during key exchange. - Bugfixes relating to link up/down status. - Bugfixes relating to logging. - make-secnet-sites made more sophisticated to support two vpns on chiark. - Documentation improvements. - Build system improvements. * Debian packaging improvements: - Native package. - Maintainer / uploaders. - init script requires $remove_fs since we're in /usr. -- Ian Jackson Thu, 12 Jul 2012 20:18:16 +0100 secnet (0.2.1-1) unstable; urgency=low * New upstream version.
