This is + incompatible with secnets earlier than 0.3.0 (September 2013), which + are all quite badly broken and should have been upgraded long ago. + * Drop support for using the same loaded rsa key with multiple different + hash algorithms (which was broken in 0.5.0). Right now we support + only `sha1' and `md5' so everyone should be using `sha1'. + Installations which specified `md5' anywhere may need config changes. + + Major new featureset (use of which is not adviseable yet): + * New facilities for negotiating about the signing keys to use for + authentication during key setup, and selecting and using the + appropriate keys. (``key-cache'/`privcache' and `peer-keys'). + Using these new facilities for keyrollover now is in principle + possible but rather complex. Further machinery is planned; + for now, retain your existing config which should keep working. + In summary: + - secnet: new `privcache' closure; + - secnet: `key-cache' and `peer-keys' keys on site closures; + - secnet: new file format for peer public keysets; + - secnet: new `make-public' config operator; + - make-secnet-sites `pub', `pkg', `serial', etc. keywords; + - make-secnet-sites --filter, --pubkeys-*, --output-version. + + More minor (logging) improvements: + * Make stderr line buffered and log to it by default. + * Do not log differently with --nodetach. + * New `prefix' option to `logfile' closure. + * Tidy and simplify some messages. + + Supporting changes: + * Many substantial internal refactorings in secnet. + * Many substantial internal refactorings in make-secnet-sites. + * make-secnet-sites option parsing totally replaced. + * Imported subtrees for base91-c and base91-python. + * New portablity code, etc.: osdep.[ch], fmemopen reimplementation. + * Explicitly define oddly-rotated dh padding arrangement (write_mpbin). + + Build system and packaging: + * Do not fail to build from git when HEAD refers to a packed ref. + * Update to subdirmk 0.3. + * Many makefile fixes (esp. to clean and cdeps). + * configure.ac: Drop or suppress some very obsolete checks. + * autogen.sh: Write a comment about need for autoheader. + * dir-locals: Provide python-indent-offset too. + + Test suite bugfixes: + * stest: Use stderr, not tty, for logging. + * stest/udp-preload.c: Fix error handling of sun_prep. + * stest: Fix breakage if nproc is not installed. + + Test suite improvements: + * New tests, including tests for new features. + * Existing tests (especially stest) generally made more thorough. + * New comprehensive-test and pretest-to-tested convenience scripts. + * Arrangements for testing with (user-provided) old secnet. + * parallel-test.*: scripts to help with parallelised bisection. + * stest: Print a lot more output about what we are doing. + * stest: Better support for cwd with longish pathname. + * stest: More flexibility, env var hooks, etc. + + -- Ian Jackson Sun, 16 Feb 2020 12:48:13 +0000 + +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: + * Credit 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). + + -- Ian Jackson Fri, 22 Nov 2019 23:13:14 +0000 + +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.
