[Opendnssec-announce] OpenDNSSEC 2.1.0 RC 1

[Yuri Schaeffer]

Dear Maintainers,

OpenDNSSEC 2.1.0 will be released soon. We've prepared a release
candidate for you to inspect.

OpenDNSSEC 2.1 development was focused on improving the daemon code for
the Signer and Enforcer. As such it is much more a steady incremental
improvement rather than revolutionary. With this style of development we
hope that a migration from 1.4, for which an end-of-life is to be given,
is facilitated.

Many of these changes are not directly visible but improve the handling
and responsiveness or unify the Signer and Enforcer code bases. These
improvements are not all mentioned in the issue list below because of
their detail. Attention has been given to different roll-over methods
and we now test fully with SoftHSMv2.

MIGRATION

If upgrading from 1.4 or earlier releases you should follow the
migration steps for 2.0. A migration first to 2.0 is not necessary. If
upgrading from a release prior 1.4.10 you should upgrade to 1.4.10 first.

FEATURES

* OPENDNSSEC-779: The Enforcer will now have an 'enforce' and
  'signconf' task scheduled per zone. 'Resalt' tasks are scheduled per
  policy. This improves performance and parallelism since no longer all
  zones need to be evaluated for work to be done. Further parallelism
  improvements in the Enforcer are on our roadmap.
* OPENDNSSEC-681: When daemonizing the Signer and Enforcer daemons fork
  to the background. Since they are then no longer able to print
  messages to the console startup problems are harder to debug. Now,
  after the fork() call the parent process will wait for the daemon to
  signal successful start and will print relevant error messages in
  case it doesn't.
* OPENDNSSEC-479: On sending notifies and initiating zone transfers the
  signer will now use the first interface mentioned in the listener
  section of conf.xml. This way the interface selection is not left to
  the OS, which could cause outgoing packets have an unexpected source
  address if multiple interfaces have a route to the destination
  address.
* OPENDNSSEC-759: The Signer doesn't need to access the HSM for every
  zone during startup anymore. This is done later by the worker
  threads. This way the signer starts quicker and is earlier available
  for user input.
* OPENDNSSEC-450: Implement support for ECDSA P-256, P-384 and  GOST.
  To be able to use this your HSM should have support as well.
  SoftHSMv2 can be compiled with support for these.
* OPENDNSSEC-503: When adding a new zone to OpenDNSSEC the Enforcer is
  a little less conservative and will add signatures and keys to the
  zone in one go. Thereby mimicking OpenDNSSEC 1.4. Effectively new
  zones are earlier fully signed by the TTL of the DNSKEY set.
* A bash autocompletion script is included in contrib for ods-enforcer
  and ods-signer. Commands, parameters, zone names and key identifiers
  can be autocompleted from the command line.

FURTHER IMPROVEMENTS

* OPENDNSSEC-530: The <Interval> tag for the Enforcer in conf.xml has
  been unused and deprecated in 2.0.  since 2.1 this tag is no longer
  allowed to be specified.
* Show help for ods-enforcer-db-setup with -h or --help
* OPENDNSSEC-836: If the listening port for Signer is not set in
  conf.xml file, the default value "15354" is used.
* OPENDNSSEC-864: ods-signer didn't print help. Also --version and
  --socket options where not processed.
* OPENDNSSEC-858: OpenDNSSEC 2.0 did print "completed in x seconds" to
  stderr for enforcer commands. This line is removed.
* SUPPORT-208: Running 'ods-enforcer key export' included a comment
  string with key properties. This is dropped to aid parsing.
* OPENDNSSEC-552: By default 'ods-enforcer key export --ds' included
  the SHA1 version of the DS. SHA1 use is discouraged in favour of
  SHA256. To get the SHA1 DS use the --sha1 flag. This flag is
  immediately deprecated and will be removed from future versions of
  OpenDNSSEC.
* OPENDNSSEC-465: ods-kaspcheck warns about algorithm mismatch between
  keys.
* When a zone is deleted the Enforcer now properly removes all tasks
  associated with that zone from its task queue.
* In the key section of the kasp.xml file, the algorithm length is no
  longer optional. For ECDSA and GHOST keys this value is ignored.
* The Enforcer and the Signer now have a HSM key cache shared between
  their threads so no longer every thread needs to iterate over all
  keys, which can potentially be very slow for some HSMs.
* OPENDNSSEC-721: Our integration testing environment now uses
  SoftHSMv2 instead of version one.
* OPENDNSSEC-844: warning when lifetime of key is smaller than
  signature validity time.
* OPENDNSSEC-311: Installation can now set the right permissions on
  used files for a configurable user/group when not running OpenDNSSEC
  as root.
* OPENDNSSEC-593: More gracefully cope when zone configured for signer
  but signconf not yet available.
* OPENDNSSEC-600: Log critical error if key is not inserted due to
  policy parameters misconfiguration.
* OPENDNSSEC-694: Domain Names in the value/answer part of records
  (e.g.  named referred to by PTR records) where mapped to lowercase.
* OPENDNSSEC-803 : Extensive logging on aborting the application.

BUGS FIXED

* OPENDNSSEC-778: Double NSEC3PARAM record after resalt.
* SUPPORT-29: signer clear <zone> would assert when signconf wasn't
  read yet.
* OPENDNSSEC-869: ds-seen command did not give error on badly formatted
  keytag.
* OPENDNSSEC-849: Crash on free of part of IXFR structure.
* OPENDNSSEC-601: signer and enforcer working dir would not properly
fallback to default when not specified.
* OPENDNSSEC-689: Failure of daemon during startup is not logged.
* OPENDNSSEC-850: Date of new transition could temporarily be incorrect.
* OPENDNSSEC-851: Change in verbosity level not immediately propagated.
* Various memory leaks, resolving compiler warnings, and static code
  analysis.
* Libxml2 cleanup improvements (Thanks he32).
