As initial examples, this branch ports the Syslog and Finger analyzers
over. We leave the old analyzers in place for now and activate them
iff we compile without any Spicy.
Needs `zeek-spicy-infra` branches in `spicy/`, `spicy-plugin/`,
`CMake/`, and `zeek/zeek-testing-private`.
Note that the analyzer events remain associated with the Spicy plugin
for now: that's where they will show up with `-NN`, and also inside
the Zeekygen documentation.
We switch CMake over to linking the runtime library into the plugin,
vs. at the top-level through object libraries.
By default this only logs all the violations, regardless of the
confirmation state (for which there's still dpd.log). It includes
packet, protocol and file analyzers.
This uses options, change handlers and event groups for toggling
the functionality at runtime.
Closes#2031
Prevent errors as follows with the bro-http2 plugin.
error in /mitrecnd_HTTP2.events.bif.zeek, line 95: identifier not defined: http2_stream_stat
error in /mitrecnd_HTTP2.events.bif.zeek, line 363: identifier not defined: http2_settings
internal error in /mitrecnd_HTTP2.events.bif.zeek, line 460: Failed to find type named: http2_settings_unrecognized_table
This allows to enable/disable file analyzers through the same interfaces
as packet and protocol analyzers, specifically Analyzer::disable_analyzer
could be interesting.
* Because frameworks/analyzer is loaded via init-frameworks-and-bifs the
dpd functionality (really just dpd.log and disabling of analyzers) is
now enabled even in bare mode.
* Not sure we need to keep frameworks/base/dpd/__load__.zeek around
or can just remove it right away.
These allow packet analyzers to register ports as identifiers to forward from
parent analyzers, while also adding those ports to the now-global
Analyzer::ports table at the same time.
This commit removes the stepping stone analyzer. It has been deactivated
by default since at least Zeek 2.0, is dysfunctional in cluster settings
and has a bunch of other issued.
Relates to GH-1573
This patch adds the ability to decap Geneve packets to process the inner
payload. The structure of the analyzer borrows heavily from the VXLAN
analyzer.
This caps size of payload strings within mqtt_publish events and
mqtt_publish.log files. A new "payload_len" field in the log file
shows the real payload size in cases where it may have been truncated.
