- Removed "binary" and "octet-stream" mime type detections. They don't
provide any more information than an uninitialized mime_type field
which implicitly means no magic signature matches and so the media
type is unknown to Bro.
- Slight change to "text/plain" signature. It's still not the most
accurate, which is reflected in its -20 strength value.
- The logic for adding file ids to {orig,resp}_fuids fields of
the http.log incorrectly depended on the state of
{orig,resp}_mime_types fields, so sometimes not all file ids
associated w/ the session were logged.
- Several places were just using old variable names or not loading
scripts correctly after they'd been renamed/moved.
- Revert/adjust a change in how HTTP file handles are generated that
broke partial content responses.
- Turn some libmagic builtin checks back on; seems some are actually
useful (e.g. text detection seems to be a builtin). The rule going
forward probably will be only to turn off a builtin if we confirm it
causes issues.
- Removed some tests that are redundant or not necessary anymore because
the generic file analysis tests cover them.
- A couple FTP tests still fail that I think need an actual solution via
script changes.
http.log now has files taken from request and response bodies in
different fields for each, and can now track multiple files per body.
That is, the "extraction_file" field is now "extracted_request_files"
and "extracted_response_files".
