+secnet (0.4.5~) unstable; urgency=medium
+
+ * INSTALL: Mention that rsa key generation might need ssh-keygen1.
+ * mobile: Fix negotiation bug with mixed old/new secnets and
+ simultaneous key setup attempts by each end. [Mark Wooding]
+ * Makefile.in: Support installation from a `VPATH' build. [Mark Wooding]
+ * Portability fixes for clang. [Mark Wooding]

+
+secnet (0.4.4) unstable; urgency=medium
+
+ Security fix:
+ * make-secnet-sites: Don't allow setting new VPN-level properties
+ when restricted. This could allow denial of service by
+ users with delegated authorisation. [Mark Wooding]
+
+ Bugfixes for poor network environments:
+ * polypath: cope properly with asymmetric routing, by correcting
+ the handling of late duplicated packets etc. Protocol is now
+ incompatible with secnet prior to 0.3.0 when either end is mobile.
+ * Randomise key setup retry time.
+
+ Other bugfixes:
+ * rsa and cbcmac: Fix configuration error messages. [Mark Wooding]
+ * Handle IPv4 addresses properly (ie, not foolishly byte-swapped),
+ when IPv6 is not available. [Mark Wooding]
+ * Better logging (and less foolish debug), especially about whether
+ key is set up, and about crossed key setup attempts.
+ * Internal refactoring and fixes. [Ian Jackson and Mark Wooding]
+
+ Build system and portability:
+ * configure: rerun autogen.sh with autoconf 2.69-10
+ * Avoid memset(0,0,0) wrt st->sharedsecret. (Fixes compiler warning;
+ in theory might cause miscompilation.) [Mark Wooding]
+
+ Documentation:
+ * README.make-secnet-sites: new documentation file. [Mark Wooding]
+ * NOTES: Describe current allocation of capability bits. [Mark Wooding]
+ * NOTES: tiny fix tot protocol description.
+ * secnet(8): Delete wrong information about dh groups. [Mark Wooding]
+
+ Administrivia:
+ * Fix erroneous GPL3+ licence notices "version d or later" (!)
+ * .dir-locals.el: Settings for Python code. [Mark Wooding]

+secnet (0.4.3) unstable; urgency=low
+
+ Security improvement:
+ * Use `mpz_powm_sec' for modexps.
+
+ Enhancements:
+ * Implement comm-info and dedicated-interface-addr feature, for
+ benefit of hippotat.
+ * Implement `keepalive' site option, to try to keep link always up.
+
+ Build etc. fixes:
+ * #include <limits.h> (fixes the build on jessie).
+ * Tolerate building from a git checkout, but with git not installed.
+ (This can happen in chroots.)
+ * Turn off -Wsign-compare for bison output.
+ * Makefile.in: Fix `check-ipaddrset' rule to get reference from
+ $(srcdir). (Makes out-of-tree builds work properly.)
+ * Release checklist fixes.
+ * Burn version numbers 0.4.1 and 0.4.2 due to errors in release prep.
+
+ Bugfixes:
+ * When printing messages about dropping IPv6, do not print anything
+ about ihl. (Check the IP version field first!)
+ * When turning on debug, turn on verbose too.

+secnet (0.4.0) unstable; urgency=low
+
+ Debugging improvements:
+ * Packet-level debugging from site notes errors from transmit.
+ * Report when transport peers updated as a result of transmit.

+secnet (0.4.0~beta2) unstable; urgency=low
+
+ Polypath bugfixes:
+ * Ignore IPv6 Unique Local unicast addresses.
+ * Skip "tentative" IPv6 local addresses.
+ * Improve logging and debug output.
+
+ Portability fix:
+ * Build where size_t is not compatible with int.
+
+ Build system and packaging fixes:
+ * Makefile: support DESTDIR.
+ * debian/rules: set DESTDIR (not prefix).
+ * debian/rules: Support dpkg-buildflags.
+ * Install ipaddrset.py and secnet.8 with correct permissions.
+ * Fix check for <linux/if_tun.h> and git rid of our copy.
+ * Use -lresolv only if inet_aton is not found otherwise.
+ * Use -lnsl only if inet_ntoa is not found otherwise.
+ * debian/rules: Provide build-arch and build-indep targets.
+ * debian/rules: Do not run build for *-indep (!)
+ * Makefile.in: Putative dual (backport and not) release build process doc.
+
+ Copyright updates:
+ * Update to GPLv3. Add missing copyright notices and credits.
+ * Get rid of old FSF street address; use URL instead.
+ * Remove obsolete LICENCE.txt (which was for snprintf reimplementation).
+ * Remove obsolete references to Cendio (for old ipaddr.py).

+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.

+
+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.
