[ldns-users] ldns 1.7.0 rc1

Dear users of ldns,

We have a release candidate for ldns 1.7.0

This is primarily a bugfix and maintenance release.  For a list of
fixed bugs and maintenance work see the Changelog below.

The most prominent change of this release is related to DANE
verification.  We received a report that verification of the DANE-TA
usage type has issues.  Also, the function prototypes that ldns exposes
do not provide means to address End Entity name verification.  Therefore
we strongly recommend to use the DANE verification functions provided by
OpenSSL >= 1.1.0 instead.

ldns has been adapted to deal with the situation as follows:
All ldns DANE verification functions will be mapped directly to
OpenSSL's >= 1.1.0 DANE verification functions.

The ldns-dane example tool will use OpenSSL >= 1.1.0 DANE functions
directly when available.

configure will fail when OpenSSL >= 1.1.0 is not available.

To compile ldns linked with an older version of OpenSSL or with
LibreSSL, one has to either

  - disable the DANE verification functions with the
    --disable-dane-verify configure option
    (the functions to create TLSA RR's will still be available), or

  - disable verification of DANE-TA usage type with the
    --disable-dane-ta-usage configure option.

    In this last case, ldns_dane_verify() will return an
    the only TLSA RR's that matched the certificate were of the
    DANE-TA usage type.

Please let us know if you want us to deal with this differently.

Because ldns will potentially have a  different set of function
prototypes (for example when compiled with --disable-dane-verify) and
because of ABI breakage in earlier versions, the .so version of this
release of ldns is bumped.  From now on .so versions will no longer
follow ldns's own version number, but will be based on libtool's version
information scheme that we also practice with libunbound and libgetdns.

Please review this release candidate carefully and let us know if
anything is wrong.  If all is well, the actual release will follow
Thursday the 15th of December 2016.

Best regards,

* Follow CNAME's when tracing with drill (TODO dnssec trace)
* Fix #551 change Regent to Copyright holder in BSD license in
  some of the headings of the file, to match the opensource.org
  BSD license.
* -e option makes ldns-compare-zones exit with status code 2 on
* Filter out specified RR types with ldns-read-zone -e and -E options
* bugfix #563: Correct DNSKEY from DSA private key. Thanks Peter Koch.
* bugfix #562: ldns-keygen match DSA key maximum size with library.
  And check keysizes with all algorithms. Thanks Peter Koch.
* ldns-verify-zone accepts only one single zonefile as argument.
* bugfix #573: ldns-keygen write private keys with mode 0600.
  Thanks Leon Weber
* Fix configure to make ldns compile with LibreSSL 2.0
* drill now also accepts dig style -y option
  (-y <[algo:]name:key> i.s.o. -y <name:key[:algo]>)
* OPENPGPKEY draft rr types. Enable with: --enable-rrtype-openpgpkey
* bugfix #608: Correct comment about escaped characters
* CDS and CDNSKEY rr type from RFC 7344.
  --enable-rrtype-cds configure option removed
* fix: Memory leak in ldns_pkt_rr_list_by_name()
  Thanks Johannes Naab
* fix: Memory leak in ldns_dname2buffer_wire_compress()
  Thanks Max Liebkies
* bugfix #613: Allow tab as whitespace too in last rdata field of types
  of variable length.  Thanks Xiali Yan
* bugfix: strip trailing whitespace from $ORIGIN lines in zone files
* Let ldns-keygen output .ds files only for KSK keys
* Parse RFC7218 TLSA mnemonics, but do not output them
* Let ldns-dane use SPKI as the default selector i.s.o. Cert
* bugfix: Fit left over NSEC3s once more before adding empty non
  terminals.  Thanks Stuart Browne

  Thanks Shussain
* bugfix #575: ldns_pkt_clone() does not copy timestamp field
  Thanks Calle Dybedahl
* bugfix #584: ldns-update fixes.  Send update to port 53, bring manpage
  in sync with the usage text, and don't alter the ldns_resolver passed
  to ldns_update_soa_zone_mname().  Created a ldns_resolver_clone()
  function in the process.  Thanks Nicholas Riley.

* Prepare for ED25519, ED448 support: todo convert* routines in
  dnssec.h, once openssl has support for signing with these algorithms.
  The dns algorithm number is not yet allocated. These features are
  not fully implemented yet, openssl (1.1) does not support the
  algorithms enough to generate keys and sign and verify with them.
