+secnet (0.5.1) unstable; urgency=medium
+
+ POTENTIALLY INCOMPATIBLE CHANGE. Some security implications.
+
+ * make-secnet-sites: Prefix names when writing secnet sites.conf file.
+
+ make-secnet-sites must copy names (vpn, location and site names) from
+ the input sites file (which is not wholly trusted) to the secnet
+ config file. Prior to this release, naming a location or site the
+ same as a secnet predefined name could generate a broken sites.conf
+ which secnet would reject. (With the existing featureset,
+ malfunctions other than rejection, eg privilege escalation, are not
+ possible.)
+
+ make-secnet-sites now adds a prefix to these names when writing
+ sites.conf. This will not affect configurations which use the
+ make-secnet-sites-provided `all-sites' key, as is usual. Other
+ configurations will break unless the references in the static part of
+ the config are adjusted.
+
+ Previous behaviour can be restored with the --no-conf-key-prefix
+ option. (Planned future enhancements to secnet are likely to make use
+ of that option, with untrusted input, dangerously insecure.)
+
+ other changes to make-secnet-sites:
+ * Fix argument parsing. Fixes a regression affecting -P in 0.5.0,
+ and also fixes new facilities introduced in 0.5.0.
+ * Sort the properties on output (and adjust the test case expected
+ outputs). Tests now pass on (at least) Python 2.7.13, 3.5.3, 3.7.5.
+ * Delete some unused code.
+
+ secnet:
+ * Change one idiom to avoid a warning from GCC9. No functional change.
+
+ build system - MAJOR CHANGES:
+ * Fix out-of-tree builds. (Broken in 0.5.0)
+ * Replace recursive make with use of the new subdirmk system.
+ This represents a fairly comprehensive overhaul of the makefiles.
+ Several bugs (esp. involving dependencies between files in different
+ directories) are fixed.
+ * Drop `make check' from `make all'. (Otherwise there is no way
+ to ask for `all' without `check'.)
+ * Suppress two unhelpful new compiler warnings from GCC9.
+ * Release checklist update.
+
+ documentation:
+ * Creit Mark Wooding properly in CREDITS.
+ * Include DEVELOPER-CERTIFICATE.
+
+ tests:
+ * Locations now have different names to sites.
+ * Somewhat better debugging output from mtest.
+ * Do not run msgcode-test except with `make fullcheck'.
+ * Other minor bugfixes and improvments.
+ * stest: Suppress unhelpful -Wno-unused-result (needed for stretch).

+
+secnet (0.5.0) unstable; urgency=medium
+
+ make-secnet-sites SECURITY FIX:
+ * Do not blindly trust inputs; instead, check the syntax for sanity.
+ Previous releases can be induced to run arbitrary code as the user
+ invoking secnet (which might be root), if a secnet sites.conf is used
+ that was generated from an untrustworthy sites file.
+ * The userv invocation mode of make-secnet-sites seems to have been safe
+ in itself, but it previously allowed hazardous data to be propagated
+ into the master sites file. This is now prevented too.
+
+ make-secnet-sites overhaul work:
+ * make-secnet-sites is now in the common subset of Python2 and Python3.
+ The #! is python3 now, but it works with Python2.7 too.
+ It will probably *not* work with old versions of Python2.
+ * We no longer depend on the obsolete `ipaddr' library. We use
+ `ipaddress' now. And this is onlo a Recommends in the .deb.
+ * Ad-hoc argument parser been replaced with `argparse'.
+ There should be no change to existing working invocations.
+ * Bad address syntax error does not wrongly mention IPv6 scopes.
+ * Minor refactoring to support forthcoming work. [Mark Wooding]
+
+ other bugfixes, improvements and changes to secnet itself:
+ * Better logging of why we are sending NAK messages.
+ * Correctly use the verified copy of the peer remote capabilities
+ from MSG3. (Bug is not a vulnerability.) [Mark Wooding]
+ * Significant internal rearrangements and refactorings, to support
+ forthcoming key management work. [Mark Wooding and Ian Jackson]
+
+ build system etc.:
+ * Completely overhaul release checklist; drop dist target.
+ * Remove dependency on `libfl.a'. [Mark Wooding]
+ * polypath.c: Fix missing include of <limits.h>. [Mark Wooding]
+ * Add a Wireshark dissector `secnet-wireshark.lua'. It is not
+ installed anywhere right now. [Mark Wooding]
+
+ documentation:
+ * Improve documentation of capability negotiation in NOTES, secnet(8)
+ and magic.h. [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]

+ * 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:

+ about ihl. (Check the IP version field first!)
+ * When turning on debug, turn on verbose too.

+ * debian/rules: set DESTDIR (not prefix).
+ * debian/rules: Support dpkg-buildflags.
+ * Install ipaddrset.py and secnet.8 with correct permissions.

+
+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.

+ SECURITY FIXES:

+ (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.
