358528732c Merge branch 'topic/robin/sqlite-merge'
Closes #997.

* topic/robin/sqlite-merge: (25 commits)
  Fix to make sqlite test consistent, and updating coverage baselines
  Avoid a CMake warning about 3rdparty looking like a number.
  Fixing linker error.
  and there is no has-reader.
  make sqlite3 executable required and add test-cases for errors
  Renaming src/external -> src/3rdparty
  fix a few small rough edges (mostly comments that do no longer apply)
  fix bug in input-manager regarding enums that a writer reads without 0-terminating the string
  actually make sqlite work again (tests passed because the writer was not actually defined because of the define.)
  add sqlite distribution.
  fix warnings, update baselines, handle rotation
  add sqlite tests and fix small vector/set escaping bugs
  fix small bug with vectors and sets.
  make work with newer AsciiFormatter.
  start adding a different text for empty records for the sqlite writer.
  no, you will never guess from where I copied this file...
  make sqlite support more or less work for logging and input
  make sqlite-writer more stable.
  make it compile with new version of AsciiInputOutput
  and adapt to AsciiInputOutput - seems to work...

641154f8e8 FileAnalysis: checkpoint in middle of big reorganization.
- FileAnalysis::Info is now just a record used for logging, the fa_file
  record type is defined in init-bare.bro as the analogue to a
  connection record.

- Starting to transfer policy hook triggers and analyzer results to
  events.

26bf99c5a3 Add parsing for GTPv1 extension headers and control messages.
Added a generic gtpv1_message event generated for any GTP message type.

Added specific events for the create/update/delete PDP context
request/response messages.

Addresses #934.

9edbf3e53c Add GPRS Tunnelling Protocol (GTPv1) decapsulation.
This currently supports automatic decapsulation of GTP-U packets on
UDP port 2152.

The GTPv1 headers for such tunnels can be inspected by handling the
"gtpv1_g_pdu_packet" event, which has a parameter of type "gtpv1_hdr".

Analyzer and test cases are derived from submissions by Carsten Langer.

Addresses #690.

1a1c798738 add SQLite reader.
Probably memleaky as hell, does not support tables/vectors yet, but it
managed to successfully read very simple tables.

009efbcb27 Major revisions to Modbus analyzer support (not quite done yet).
- Renamed many data structures to align with most recent standard.

- Reworked modbus events to make them more canonically "Bro".

- Converted the Modbus analyzer to a simpler style for easier maintenance.

- Modbus coil related events still don't work (I haven't finished the
  function for converting the data structures).

- Modbus file record events remain incomplete.

6e0d15b55e basic sqlite writer seems to work.
does not support table and vector types because SQLite has no support for arrays.
also does not support rotation, etc.

Not really tested thoroughly - but starting bro with Log::default_writer=Log::WRITER_SQLITE
yields a couple of sqlite files that seem to contain sensible stuff.

b8e1604ab5 Make tunnels always identifiable by UID, tunnel.log now gets populated.
conn.log now sets a field indicating all the parent tunnel UIDs over
which a connection operated and cross reference the UIDs found in
the tunnel.log.

Also some renaming of tunnel related types at the scripting layer.

2a79fe95ec Another tunneling checkpoint.
- AYIYA works.
  - AYIYA analyzed connections are still labelled wrong in conn.log (logged as syslog)
- Some clean up for left over code.
- Small refactoring to pass packets back from analyzers to core.
- $uid is now optional in conn logs since ip-in-ip tunnel parent's
  won't have an actual connection.

b51dd191d7 Refactor IP-in-IP tunnel support.
UDP tunnel support removed for now, to be re-added in specific
analyzers later, but IP-in-IP is now decapsulated recursively
so nested tunnels can be seen and the inner packets get sent
through the IP fragment reassembler if necessary.

952b6b293a Merging in DataSeries support from topic/gilbert/logging.
I copied the code over manually, no merging, because (1) it needed to
be adapted to the new threading API, and (2) there's more stuff in the
branch that I haven't ported yet.

The DS output generally seems to work, but it has seen no further
testing yet.

Not unit tests yet either.

57ffe1be77 completely change interface again.
compiles, not really tested.

basic test works 70% of the time, coredumps in the other 30 - but was not easy to debug on a first glance (most interestingly the crash happens in the logging framework - I wonder how that works).
Other tests are not adjusted to the new interface yet.

91943c2655 * rework script interface, add autostart stream flag that starts up a stream automatically when first filter has been added ( probably the most common use case )
* change internal reader interface again
* remove some quite embarassing bugs that must have been in the interface for rather long
* add different read methods to script & internal interface (like normal, streaming, etc). Not implemented in ascii reader yet.

9c388a1809 Adding support to de-capsulate tunnels.
Checkpoint.
Decapsulation happens after IP Defragmentation. The "identity" of the
enclosing tunnel (the "parent") is added to the connection record of the
child (tunneled) connection as an optional field $tunnel_parent.

ab15437339 Working on the logging API exposed to scripts.
- Moving all functions into the Log::* namespace, using the recent
  bifcl updates. Moved logging-specific stuff to logging.bif.

- Log::create_stream() now takes a record Log::Stream as its second
  argument, which specifies columns and (optionally) the event.

- All the internal BiFs are now called "Log::__<something>", with
  script-level wrappers "Log::<something>". That first allows to add
  additional code at the script-level, and second makes things better
  comprehendible as now all relevant functionality is collected (and
  later documetned) in policy/logging.bro.

- New function Log::flush(id), which does the obvious assuming the
  writer supports it.

- add_default_filter() is now called implicitly with every
  create_stream(). Seems that we usually want that functionality, and
  when not, remove_default_filter() gets rid of it.

- The namespace of a stream's ID is now used as the default "path"
  (e.g., if the namespace is SSH, the default log file is "ssh.log").

- Updated policy/test-logging.bro as well as the btest tests according
  to these changes.
