There are two new script level functions to query and lookup files
from the core by their IDs. These are adding feature parity for
similarly named functions for files. The function prototypes are
as follows:
Files::file_exists(fuid: string): bool
Files::lookup_File(fuid: string): fa_file
In ContentLine_Analyzer, prevent excessively long lines being assembled.
The line length will default to just under 16MB, but can be overriden on
a per-analyzer basis. This is done for the finger,ident, and irc
analyzers.
a broctl print triggers this error
Reporter::ERROR no such index (Cluster::nodes[Intel::p$descr])
/usr/local/bro/share/bro/base/frameworks/intel/./cluster.bro, line 39
when broctl connects p$descr is empty. It should probably be set to
'control' somewhere inside broctl, but that would only fix broctl, not
other clients.

When Bro writes a compressed log, it uses a file extension of ".gz".
However, upon log rotation the ascii writer script function
"default_rotation_postprocessor_func" was discarding the ".gz"
file extension. Fixed so that the correct file extension is
preserved after rotation.
- Addresses Philip Romero's question from the Bro mailing list.
- Adds Microsoft Edge as a detected browser.
- We are now unescaping encoded characters in software names.
With this commit, the data structure that is transfered for notice
suppression is much smaller than before, not including potentially
complex data structures like the fa_file record.
This feature can be enabled globally for all logs by setting
LogAscii::gzip_level to a value greater than 0.
This feature can be enabled on a per-log basis by setting gzip-level in
$confic to a value greater than 0.
The changes are now a bit more succinct with less code changes required.
Behavior is tested a little bit more thoroughly and a memory problem
when reading incomplete lines was fixed. ReadHeader also always directly
returns if header reading failed.
Error messages now are back to what they were before the change, if the
new behavior is not used.
I also tweaked the documentation text a bit.
By default, the ASCII reader does not fail on errors anymore.
If there is a problem parsing a line, a reporter warning is
written and parsing continues. If the file is missing or can't
be read, the input thread just tries again on the next heartbeat.
Options have been added to recreate the previous behavior...
const InputAscii::fail_on_invalid_lines: bool;
and
const InputAscii::fail_on_file_problem: bool;
They are both set to `F` by default which makes the input readers
resilient to failure.
The extensions now work with optional types, as well with complex types
(like subrecords). Not returning a record in the ext_func no longer
crashes bro.
The default_ext_func was switched to return void in
cases where no extension revord is defined (was bool).
I also got rid of the offsets in the indices - with the rest of the
implementation, that was not really necessary and made the code more
complex.
The "metadata" functionality has been renamed to "ext" to
represent that the logs are being extended. The function that
returns the record which is used to extend the log now receives
a log filter as it's single argument.
The field name "unrolling" is now renamed to "scope" so the variables
names now look like this: "Log::default_scope_sep"
If the analyzer is not found directly attached to the connection,
useless error messages are being output. There are now several
cases where analyzers are attached within other analyzers so the
connection itself doesn't know about the analyzer. This hides
these useless messages.
This adds the capability for the user to attach a reason when removing
or destroying a rule. The message will both be logged in netcontrol.log
and forwarded to the responsible plugins.

Currently outstanding_global_views values are only decremented during
the end of epoch cleanup, but not when handle_end_of_result_collection
is called for the specific uid that actually triggered the result
collection (which is specifically NOT a cleanup event).
This changes outstanding_global_views values to be a set of outstanding
uids, instead of a count. This allows handle_end_of_result_collection
to remove any uids from the set as it sees them.
Previously, recent_global_view_keys was only tracked on workers causing
a popular key to be sent up and handled by the manager once for each
worker.
This records the key inside recent_global_view_keys on the manager after
the first update, making the rest of the updates no-ops.
Additionally, since the counter value was never used, it has been
changed from a table to a set.
This adds an event that is raised once Catch & Release ceases the
block management for an IP address because the IP has not been seen in
traffic during the watch interval.
This allows users who use their own logic on the top of catch and
release know when they will have to start re-blocking the IP if it
occurs in traffic again.
This change introduces error events for Table and Event readers. Users
can now specify an event that is called when an info, warning, or error
is emitted by their input reader. This can, e.g., be used to raise
notices in case errors occur when reading an important input stream.
Example:
event error_event(desc: Input::TableDescription, msg: string, level: Reporter::Level)
{
...
}
event bro_init()
{
Input::add_table([$source="a", $error_ev=error_event, ...]);
}
For the moment, this converts all errors in the Asciiformatter into
warnings (to show that they are non-fatal) - the Reader itself also has
to throw an Error to show that a fatal error occurred and processing
will be abort.
It might be nicer to change this and require readers to mark fatal
errors as such when throwing them.
