work fine now.
Todo:
* update all baselines
* fix the circular reference to the fa_file structure I introduced :)
Sadly this does not seem to be entirely straightforward.
addresses BIT-953, BIT-760
This supports parsing of SNMPv1 (RFC 1157), SNMPv2 (RFC 1901/3416), and
SNMPv2 (RFC 3412). An event is raised for each SNMP PDU type, though
there's not currently any event handlers for them and not a default
snmp.log either. However, simple presence of SNMP is currently visible
now in conn.log service field and known_services.log.
If reading a trace file w/ only TCP control packets, a warning is
emitted to suggest the 'detect_filtered_traces' option if the user
doesn't desire Bro to report missing TCP segments for such a trace file.
the ssl-analyzer and the topic/bernhard/x509 branch.
Simply prints information about the encountered certificates (I have
not yet my mind up, what I will log...).
Next step: extensions...

- This caused us to lose signatures for POP3 and Bittorrent. These will
need discovered in the repository again when we add scripts
for those analyzers.
Thanks to git this merge was less troublesome that I was afraid it
would be. Not all tests pass yet though (and file hashes have changed
unfortunately).

This is a larger internal change that moves the analyzer
infrastructure to a more flexible model where the available analyzers
don't need to be hardcoded at compile time anymore. While currently
they actually still are, this will in the future enable external
analyzer plugins. For now, it does already add the capability to
dynamically enable/disable analyzers from script-land, replacing the
old Analyzer::Available() methods.
There are three major parts going into this:
- A new plugin infrastructure in src/plugin. This is independent
of analyzers and will eventually support plugins for other parts
of Bro as well (think: readers and writers). The goal is that
plugins can be alternatively compiled in statically or loadead
dynamically at runtime from a shared library. While the latter
isn't there yet, there'll be almost no code change for a plugin
to make it dynamic later (hopefully :)
- New analyzer infrastructure in src/analyzer. I've moved a number
of analyzer-related classes here, including Analyzer and DPM;
the latter now renamed to Analyzer::Manager. More will move here
later. Currently, there's only one plugin here, which provides
*all* existing analyzers. We can modularize this further in the
future (or not).
- A new script interface in base/framework/analyzer. I think that
this will eventually replace the dpm framework, but for now
that's still there as well, though some parts have moved over.
I've also remove the dpd_config table; ports are now configured via
the analyzer framework. For exmaple, for SSH:
const ports = { 22/tcp } &redef;
event bro_init() &priority=5
{
...
Analyzer::register_for_ports(Analyzer::ANALYZER_SSH, ports);
}
As you can see, the old ANALYZER_SSH constants have more into an enum
in the Analyzer namespace.
This is all hardly tested right now, and not everything works yet.
There's also a lot more cleanup to do (moving more classes around;
removing no longer used functionality; documenting script and C++
interfaces; regression tests). But it seems to generally work with a
small trace at least.
The debug stream "dpm" shows more about the loaded/enabled analyzers.
A new option -N lists loaded plugins and what they provide (including
those compiled in statically; i.e., right now it outputs all the
analyzers).
This is all not cast-in-stone yet, for some things we need to see if
they make sense this way. Feedback welcome.

Final touches to modbus analyzer for now.
Major revisions to Modbus analyzer support (not quite done yet).

Modbus analyzer, current support: FC=3,4,5,6,7,16,22,23
Closes#915.
- I added this to the base scripts because it's very minimal overhead
and we get questions about this all the time. Now that reporter
messages are printed to the console, people will see the message
clearly if they have bad checksums.

I cleaned up the code a bit, mainly layout style.
I did not include the *.bro scripts for now, but a test script
../testing/btest/scripts/base/protocols/modbus/events.bro that prints
out the value for each event.
Merged the Modbus traces from the ics repository into a single trace
as input for the test. They currently trigger 20 of the 34 events.
Addresses #870.
