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.
* origin/topic/jsiwek/lambda-name-fixes:
Guarantee unique internal name for each lambda function
Use consistent hashing method for internal lambda function names
Now, in addition to setting thresholds for bytes and packet, one can set
a threshold for connection duration. Note that the threshold event is
only raised once the next packet in the connection is seen.
This also fixes a small pre-existing bug, in which a bunch of warnings
were raised if someone just used the lower-level functions without going
through the higher-level scripting API.
* origin/topic/seth/mqtt:
Bug fixes and test baseline updates
Fix an issue with bro_init -> zeek_init
MQTT Analyzer heavily updated and ported from the analyzer originally by Supriya Kumar
Adjustments during merge:
* Minor whitespace cleanups
* Some bro to zeek renaming
* Fixed the parsing of unsubscribe messages to generate an event for each topic
The results of std::hash<std::string> may vary depending on platform.
E.g. test suite failed on macOS due to Linux generating different lambda
function names.
* origin/topic/dev/non-ascii-logging:
Removed Policy Script for UTF-8 Logs
Commented out UTF-8 Script in Test All Policy
Minor Style Tweak
Use getNumBytesForUTF8 method to determine number of bytes
Added Jon's test cases as unit tests
Prioritizes escaping predefined Escape Sequences over Unescaping UTF-8 Sequences
Added additional check to confirm anything unescaping is a multibyte UTF-8 sequence, addressing the test case Jon brought up
Added optional script and redef bool to enable utf-8 in ASCII logs
Initial Commit, removed std::isprint check to escape
Made minor code format and logic adjustments during merge.
This analyzer generates three logs to fully display what is happening over the MQTT connection.
- mqtt_connect.log
- mqtt_subscribe.log
- mqtt_publish.log
At this time it only supports MQTT 3.1 and 3.1.1
* origin/topic/timw/cleaner-utf8:
GHI-486: Switch over to using LLVM utf8-checking code to better validate characters
I addressed a buffer over-read during the merge and added test-cases for
it.
When generating some events for PE and X509 file analyzers, there's
an invalid cast from file_analysis::Analyzer to analyzer::Analyzer
and subsequent invalid member access via analyzer::Analyzer::GetID()
called on what is really a pointer to a file analyzer.
* origin/topic/zeke/expire-func:
Ignore abs-path in test.
Report argument # type check failed on.
Update test baseline.
Improve func arg type checking.
&expire_func(table, arg1, arg2, ...) + type checking.
* topic/timw/algorithms:
Remove List::append deprecation
Mark List::append/insert deprecated in favor of push_back/push_front for consistency with Queue
Mark List::sort as deprecated, remove List::sortedinsert
Change container iterators to just use pointers directly into the container elements
