-secnet (0.4.4~) unstable; urgency=medium
+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.

+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]

+
+ * 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
Bugfixes for poor network environments:
* polypath: cope properly with asymmetric routing, by correcting
- the handling of late duplicated packets.
+ 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:
* Fix erroneous GPL3+ licence notices "version d or later" (!)
* .dir-locals.el: Settings for Python code. [Mark Wooding]
