Subject: [dnscap-users] Release 2.0.0
Message-ID: <b5a5fb97-2158-ed91-2086-9e9259185c39@dns-oarc.net>

Hi all,

This major release contains three backward incompatible changes, two new
command line options and a completely restructured man-page(!), please
read the change notes carefully before upgrading!

  387731b95ca63d84e602f3f975497da83908ea6f595f88d599d7d277d6fe30f0

Packages are available at: <https://dev.dns-oarc.net/packages/>

The first backward incompatible change has to do with the removal of
libbind dependency. This library was causing segfaults on OpenBSD due to
shared (and overwritten) symbols with OpenBSD's libc.
It was replaced with LDNS and LDNS renders domain names as Fully
Qualified Domain Names (FQDN, the trailing dot!) so every output of a
domain name has been changed to a FQDN.
This also changes `-X`/`-x`, which will now match against FQDNs.

The second backward incompatible change is that `-6` has been removed.
This was used to alter the BPF in order to "fix" it, dnscap adds
specific filters to IP and UDP headers which does not work for IPv6 traffic.
The generated BPF has been changed to allow IPv6 to always pass, making
the option obsolete. IPv6 filtering is then done in dnscap.

The last backward incompatible change has to do with the output format
of `-g` related to EDNS0 and is now more consistent with the rest of the
parsable output:
- No more spaces in the output
- Fix incorrect `\` and extra empty new-line
- All EDNS0 options are added after `edns0[...]` using comma
  separation, example: `edns0[],edns0opt[],...`
- Client Subnet format:
  `edns0opt[ECS,family=nn,source=nn,scope=nn,addr=...]`
- Unknown/unsupported code: `edns0opt[code=nn,codelen=nn]`
- Parsing error messages have changed, they came from libbind, now
  comes from LDNS

New options:
- Add `-q` and `-Q` to filter on matched/not matched QTYPE

Bugfixes:
- Fix memory leak in EDNS0 ECS address parsing
- `network`: Fix sonarcloud issues, potential `memcpy()` of null
  pointer

Other changes:
- Fix CBOR output inclusion, LDNS is always available now
- Add macros for Apple and Windows endian functions
- Restructure and correct the man-page
