[ldns-users] ldns 1.8.3 quickfix release

[Willem Toorop]

Dear all,

Version 1.8.2 of ldns had a crash bug when creating packets with an EDNS 
OPT resource record without options. For example when just setting the 
DO bit (DNSSEC OK) or when specifying a larger UDP payload size.

This quick fix release has this resolved. Also the unit tests have been 
reviewed and updated to catch this in the future before release.

Compared to the 1.8.1 release, this release has some bugfixes and a few 
new features, most notably:

* Since draft-ietf-dnsop-svcb-https will become RFC now anytime soon,
   SVCB and HTTPS RR types are now compiled by default.

* Functionality for parsing and printing of EDNS0 Options.

   The list of options in a packet can be accessed via a new function:
   ldns_pkt_edns_get_option_list(ldns_pkt *packet). The list can be
   further manipulated with functions as described in edns.h. Finally
   the options can be converted to presentation format with
   ldns_edns_option_list2buffer_str() from host2str.h.

   drill will now also print EDNS0 options in a parsed format.

=========
1.8.3   2022-08-15
         * bugfix #183: Assertion failure with OPT record without rdata.
           This caused packet creation with only a DO bit (for DNSSEC OK)
           to crash. Thanks Anand Buddhdev and others for reporting this
           so quickly.
