Removal of barnyard2 and unified2 support

Hello,

with Zeek 5.1 we’re planning on removing (without deprecation) scripts and analyzers related to Snort/Unified2 integration.

Concretely:

  • the barnyard2 policy scripts
  • the unified2 file analyzer and related policy scripts

The former employs brocolli for communicating with Zeek and so can’t have been working with any modern version of Zeek for quite a bit, the latter is assumed to have no users.

Please get in touch if you do have a use for this functionality.

Thanks,
Arne
