2.1

New Features

    - donuts:       - Added the ability to summarize information
                      about a zone in the output, such as the upcoming
                      entire zone expiry time, etc
                    - Added the ability to query live zones for
                      records to analyze.  EG:

    - libval:       - Add support for conditionally checking all RRSIGs
                      on an assertion even if one that validates is
                      already found.
                    - Look for zonecuts based on NS records, not SOA
                    - Added initial support for TSIG in order to enable
                      libval to query recursive name servers that
                      authorized recursive lookup for only those hosts
                      that used a particular TSIG key.

                     (requires software upgrades on both sensor and
                      manager at the same time)
                    - added -restart option to owl-sensord for

                      sensor modules, and Owl manager
                    - Use rlimits to try and limit file descriptor use in
                      libsres so we don't run out of available sockets.
                    - Eliminate a few hardcoded paths in various perl modules

2.0

New Features

Bloodhound

A mozilla-based DNSSEC-enabled browser with DANE support - Added support for validation of SSL certificates using the DANE protocol.

Owl

The Owl Monitoring System uses timed DNS queries to monitor basic network functionality. The system consists of a manager host and a set of sensor hosts. The Owl sensors perform periodic DNS queries and report to the Owl manager the time taken for each query. Over time, this shows the responsiveness of the DNS infrastructure.

dnssec-nodes

Many new features have been added: - The validation tree now supports clicking on boxes to highlight it and the arrows that derive from it. Great for use when teaching about DNSSEC. - An extensive filter/effect editor now lets you tailor the look of a graph to color-code, set the alpha levels, etc of nodes based on their names, status, data types, etc. - Right clicking on a node lets you center the graph on that node. - More data types are collected and shown in the data view. - Support for arguments on the command line for parsing log files, pcap files and domain names. - The validation view has received a visual clean-up - Many other bug fixes

curl

- Added support for validation of SSL certificates using the DANE protocol.

libval

- Added support for local DANE validation - Extended the dt-danechk commandline tool to check the X509 cert provided over the SSL connection against the TLSA record. - Optimized glue record lookup when the only ip addresses configured for the host are for a single address family (ipv4 or ipv6) - fine tune res_io source management

dnssec-check

dnssec-check now checks DNAME support

rollerd

A new set of steps for KSK rollover has been implemented. A cache-expiration wait phase has been moved after the publication of DS records in order to allow name caches to reflect the changes. In addition to rollerd, supporting program have been modified to recognize this change.

rollrec files

A new "information rollrec" has been added to the rollrec files. This will allow infomration to be specified for the collection of rollrecs. At this time, the only information stored in this rollrec is the version number of the rollrec file. In addition to the rollrec.pm Perl module, programs which use this module have been modified to recognize this change. If you use the rollrec.pm module, you should test to see if your code is affected. The modifications for the info rollrec have been made to minimize affected programs. If you parse the rollrec files yourself, you will have to account for this change.

multiple

The perl-based tools can now use either the ZoneFile::Fast or the Net::DNS zone file parser, thanks to a patch from Sebastian Schmidt (yath@yath.de).

ZoneFile:Fast

- Support for TLSA - Made it compatible with newer Net::DNS releases

Qt5

- A patch to support DNSSEC checks in Qt5 DNS lookups

Bug Fixes

zonesigner

- Fixed SOA parsing and serial number update issues

libval

- Properly initialize memory in sockaddr structures before use.

1.14

New Features

dnssec-nodes

Many new features, including validation tree graphing, on-the-wire traffic display, pcap dump file display, increased data logging and display, improved simultaneous updating, etc.

Libval:

Added initial support for the TLSA rrtype - Added support for ECDSA - Implemented checking for AI_ADDRCONFIG in getaddrinfo - Memory optimizations to improve speed-up

dnssec-check

increased stability across all platforms. - All Around: - Many bug fixes and other minor improvements

1.13

New Features

rollerd:

Added support for the signzone command. Allow zones to be signed while in the midst of a rollover wait. - Added autosigning of modified zone files. Zone files are considered modified when their "last modification" timestamp is more recent than that of the associated signed zone file. This functionality includes adding the -autosign option and config field. - Added additional commands (via rollctl) to allow greater control over zone rollover actions. - Added -zsargs option to allow global options to be passed to zonesigner.

realms:

Added the realms feature to manage multiple simultaneous rollover environments. Several commands and modules (e.g., dtrealms, realms.pm, buildrealms) were added for the realms feature.

zonesigner:

Added the -threshold option to specify a signing threshold. - Better handling of serial numbers in zone files.

keymod:

New tool that can be used to modify key generation parameters in a keyrec file.

dnssec-check

significant rewrite since the 1.12 release, though individual updates have been available already. - Asynchronous support for non-interrupting GUI support - Letter grades assigned to each resolver - Various user-interface improvements

libval:

Bug fixes - Renamed all validator command-line apps to have a dt- prefix in order to avoid conflicts with pre-existing executables in certain platforms. - dnsval python module - Add python wrapper module for the validator library. Code contributed by Bob Novas.

trustman:

Added an option for use by monitoring systems.

nagios

Added the dt_donuts plugin for running trustman on remote machines. - Added the dt_trustman plugin for monitoring trust anchors.

firefox

updated nspr and firefox patches to work with mozilla-central and nspr-4.9

Added the ability to perform DNSSEC operations on DNSSEC-Tools managed signed zones using the Webmin front-end.

ssh:

Update the patch for enabling local DNSSEC validation to work with OpenSSH 6.0p1.

1.12.2

Bux fix release

Rollerd's

alwayssign flag logic had a critical error that could have caused a zone to be signed with the wrong ZSK at particular points of the ZSK key rolling process.

1.12.1

Minor bug fix release

- Fix perl Validator module so it compiles after a header move

1.12

New Features:

libval:

Made improvements to support IPv6, added the ability to fetch IPv6 glue - Fixed the EDNS0 fallback behavior. - Tidied up the locking semantics in libval. - Added support for hard-coding validator configuration information that gets used in the absence of other configuration data. This feature allows the validator library to be self-contained in environments where setting up configuration data at specific locations in the file system is not always feasible. - The library has been ported to the Android OS

rollerd:

Added support for phase-specific commands. This allows the zone operator to customize processing of the rollerd utility during different rollerd phases. - Added support for zone groups. This allows a collection of zones to be controlled as a group, rather each of those zones individually. - Improved the manner in which rollerd indexes the zones being managed, with the significantly decreased access times for rollerd's data files. This results in rollerd being able to support a lot more zones with a single rollerd instance. - rollctl and the rollover GUI programs may have new commands to allow for immediate termination of rollerd.

apps

Added patch to enable local validation in NTP, with the ability to handle a specific chicken and egg problem related to the interdependency between DNSSEC and an accurate system clock. - Added a patch to enable DNSSEC validation in Qt based applications

dnssec-check

Completely rewritten GUI with many new features - Now contains the ability to submit the results to a central DNSSEC-Tools repository. The results will be analyzed and published on a regular basis. Please help us get started by running dnssec-check on your networks! Note that it explains that it only sends hashed IP addresses to our servers and the reports generated will be aggregation summaries of the data collected. - It now runs on both Android and Harmattan (N9) devices

maketestzone

Now produces zones with wildcards and changes to NSEC record signatures

dnssec-nodes

parses unbound log files - Initial work porting to Android

dnssec-system

tray - parses unbound log files

1.11

New Features:

libval:

Significant improvements and bug fixes to the asynchronous support. - Added asynchronous version of val_getaddr_info. - Some reworking of the asynchronous API and callbacks. Note the asynchronous api is still under development and subject to changes that break backwards compatibility.

rollerd:

Added an experimental time-based method for queuing rollover operations. This original method (full list of all zones) is the default queuing method, but the new method can be used by editing the rollerd script. rollctl and rollrec.pm were also modified to support this change. - Added support for merging a set of rollrec files. rollctl and rollrec.pm were also modified to support this change.

dnssec-nodes

This graphical DNS debugging utility was greatly enhanced - Now parses both bind and libval log files - Multiple log files can be watched - Node's represent multiple data sets internally, which are independently displayed and tracked. - Added support for searching for and highlighting DNS data and DNSSEC status results

dnssec-system

tray - This utility can now report on BOGUS responses detected in both libval and bind log files. - Summary window revamped to group similar messages together. Plus many more minor features and bug fixes

1.10

New Features:

- New Apps: (see the validator/apps directory for details) - dnssec-check: check dnssec support from your ISP - dnssec-nodes: graphically displays a DNS hierarchy, color coded by each node's DNSSEC status - dnssec-system-tray: displays pop-up notifications when a libval-enabled application triggers a DNSSEC error - lookup: a graphical DNS lookup utility that displays the results in a hierarchical tree and color codes the window according to DNSSEC status

libval:

Added support for building on Windows. & libsres - added support for falling back to recursion when the caching name server does not appear to support DNSSEC. This also works as a mechanism to work around a poisoned or misbehaving cache. - Significant improvements to the asynchronous support.

lsdnssec:

Improvements to lsdnssec to display different output depending on whether a zone is a stand-alone zone or under control of rollerd.

nagios:

Plugins for the nagios monitoring system which enable monitoring of zone rollover states.

firefox:

Updated patches that work with the most recent firefox Plus many more minor features and bug fixes

1.9

New Features:

lsdnssec:

Added a new flag (-p) to show only zones in a particular rollerd phase. - fixed bugs to align timing output with rollerd.

rollerd:

Added a -logtz flag for logging timezones - fixed bugs related to the -alwayssign flag. - zonesigner's path is taken from the config file.

rollctl:

Added -rollall and -rollzone options.

zonesigner:

Assumes keys need to be generated for new zones (Assumes -genkeys option was given if a keyrec file can't be found.) - Exits with unique exit codes if a failure occurs. ("zonesigner -xc CODE" can lookup a description for it.") - Added the -phase option so rollover options could be more easily specified.

lights:

A simple GUI to check the status of rollover states

blinkenlights:

Added hide/show commands for rollrec names and zone names, for split-zone support

cleankrf:

Fixed deletion of obsolete set keyrecs. - GUI commands: - Fixed how the Exit command works so they don't coredump. - libsres & libval: - New beta support for issuing asynchronous requests. This can speed up queries by up to 4 times if used. (see example code in validator/apps/validator_selftest.c) - NSEC3, DLV and IPv6 are enabled by default. - improved logging and logging-callback support.

drawvalmap

Can output PNG files now

Packaging:

- Our download page now allows you to download the C validator libraries independently of the full DNNSEC-Tools tool-suite.

Many bugs were also fixed in the 240+ changes.

1.8

New Features:

- zonesigner, rollerd - Made changes so that these tools are more compatible with recent versions of Bind - The zone_errors configuration parameter allows a zone- specific maximum to be set. Once exceeded, that zone will be skipped rather than allowing rollover to continue. - blinkenlights - Recognizes when rollerd abruptly quits, so error messages aren't spewed interminably.

ZonFile::Fast

Fixed parsing of DS records containing spaces and parsing of mname and rname SOA fields - Added support for parsing KEY records

keyrec.pm

Made changes to properly lock keyrec files before writing to them. - Begun process of deprecating keyrec_open().

mapper:

added a new option: --node-size for mapping complex zones.

dnspktflow:

added two new options: --layout-style for selecting the layout style to use --node-size for mapping complex zones. - Add new (default) option to cluster authoritative nodes together to help better understand the relationships between traffic patterns and authoritative name server/zone arrangement.

libval:

Now distributed with the Root TA. - Added stricter checks for openssl SHA-256 support in configure. - Added several improvements that allow the validator to lookup information within provably insecure zones that do not handle EDNS0 requests nicely. This includes adding support for turning off EDNS0 when traversing a name hierarchy that leads to a provably insecure zone, EDNS0 fallback support, and additional checks to check the sanity of response data. - Fixed certain bugs in CNAME handling and in the validation of proofs accompanying wildcard responses, referrals and alias chains. - Fixed support for RSADSA and RSASHA-512 signature validation. - Mac OSX: - Added a Ports file for mac ports - updated the fink build spec

many other miscellaneous bug fixes and improvements.

1.4.1

Security Issue:

The DNSSEC-Tools libval validating resolver library does suffer from the same issues that the other DNS resolvers were faced with as described by: http://www.kb.cert.org/vuls/id/800113 Although DNSSEC will prevent the issues, it is assumed that not everyone is using libval with only 100% DNSSEC protected zones. The supporting tools that do not use libval are not affected by this problem (eg, zonesigner, rollerd, donuts, etc are just fine).

NSEC3 value change

Now that the NSEC3 RFC has been published we've changed the internal numeric RR code to the assigned value. The NSEC3 code, however, is still considered experimental and not fully tested.

1.4

Documentation:

- Much more extensive documentation has been written about the tools and how to get started using them. See the following web page for details: http://www.dnssec-tools.org/wiki/index.php/Tutorials

Applications:

- trustman has seen a lot of usability improvements and now has more extensive documentation. - rollerd and it's controlling scripts can now handle user initiated KSK rollovers. - zonesigner handles keys stored in other directories better. - donuts output has been made more user friendly and the verbosity level can now be more finely tuned. - donuts rule definitions have been cleaned up and the API for writing rules has been simplified.
