642ef5d3c1 Tweaking how HTTP requests without URIs are handled.
The change from #49 made it an error to not have a URI. That however
then led requests with an URI yet no version to abort as well.
Instead, we now check if the token following the method is an "HTTP/"
version identifier. If, so accept that the URI is empty (and trigger
a weird) but otherwise keep processing.

Adding test cases for both HTTP requests without URI and without
version.

faabe8a5e3 Fixes for file type identification.
- Backed out eTag changes.  The real world is more complicated
   than just using eTags to identify the same file.
 - A bit of code simplication in the http base scripts.
 - Test updates (more existing small problems were identified!).

22bf3e1196 Increase UIDs to 96 bits w/ C/F prefix - BIT-1016
- The bit-length is adjustable via redef'ing bits_per_uid.

- Prefix 'C' is used for connection UIDS (including IP tunnels) and
  'F' for files.

939619889d File analysis fixes and test updates.
- 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.

705a84d688 Improve tracking of HTTP file extraction (addresses #988).
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".

037d582b0e FileAnalysis: add custom libmagic database.
- It's derived from the magic database of libmagic 5.14, but with most
  everything not related to mime types removed.

- The custom database is always used by default for mime detection, but
  the more verbose file type detection will fall back on the default
  libmagic installation's database.  The result is: mime type strings
  are now guaranteed to be consistent across platforms, but the verbose
  file type descriptions are not.

- The custom database gets installed in $prefix/share/bro/magic, and
  should even be extensible if files with new patterns are added inside
  the directory.

- The search path for the mime magic database can be controlled via
  BROMAGIC environment variable.

- Remove mime_desc field from ftp.log.

- Stop using the mime/file type canonifier with unit tests.

- libmagic >= 5.04 is now a requirement.

84a0c2fdac FileAnalysis: file handles now set from events.
Versus from synchronous function calls, which doesn't work well because
the function call can see a script-layer state that doesn't reflect
the state as it will be in terms of the event/network stream.

e2d20cb7bc Changing the HTTP parser to accept methods that align with the RFC. 2012-12-07 19:42:03 -08:00

57510464a1 Adapting the HTTP request line parsing to only accept methods
consisting of letters [A-Za-z].

I had some bogus HTTP sessions now with the test-suite that reported
data as HTTP because it started with "<!... ". Requiring letters seems
a reasonable constraint.

177c014cb7 Merge remote-tracking branch 'vlad/topic/vladg/http-verbs'
* vlad/topic/vladg/http-verbs:
  A test for HTTP methods, including some horribly illegal requests.
  Remove hardcoded HTTP verbs from the analyzer (#741)

I added a "bad_HTTP_request" weird for HTTP request lines that don't
have more than a single word.

Closes #741.
