- New script extracted from weird.bro to implement the
connection related "weird" data into an optionally
loaded script.
- Adjusted the default notice tuning to stop ignoring
the connection related weirds since they aren't loaded
by default anymore.
- Fixed a bug where notices were being passed to proxies.
This was a mistake and should greatly reduce load on
many clusters.
- Cluster event regex variables renamed to:
- Notice::manager2worker_events
- Notice::manager2proxy_events
- Notice::worker2manager_events
- Notice::worker2proxy_events
- Notice::proxy2manager_events
- Notice::proxy2worker_events
- The default Notice::policy set is cleared for all cluster
nodes except for managers to cause all default notice
processing to occur on managers. This should reduce load
on workers slightly.
- scan.bro and hot.conn.bro will be returning soon.
- The rest are going to return as updated protocol analysis
scripts and new/updated frameworks later.
Updated README and collected coverage-related tests in a common dir.
There are still coverage failures resulting from either the following
scripts not being @load'd in the default bro mode:
base/frameworks/time-machine/notice.bro
base/protocols/http/partial-content.bro
base/protocols/rpc/main.bro
Or the following result in errors when @load'd:
policy/protocols/conn/scan.bro
policy/hot.conn.bro
If these are all scripts-in-progress, can we move them all to live
outside the main scripts/ directory until they're ready?
- Fixed the notice_policy log.
- Predicate functions are now logged.
- Predicate functions are now optional. If not given, it's assumed that
the result should always apply.
* origin/topic/seth/notice-suppression:
Updated a notice related baseline and added a necessary @load line.
Notice suppression clean up and notice/cluster integrtion fixes.
Updates for notice suppression to use the &create_expire attribute
Small, mostly cosmetic updates and fixing a test.
Fix crash on exit (addresses #607).
Duplicate notice suppression.
Closes#623.
* origin/fastpath:
Fix PktSrc setting next_timestamp even when no packet available
Fix lack of NUL-termination in to_upper/to_lower BIF's return val.
Fixing unit tests and some minor bugs.
Fix broctl cluster log rotation (addresses #619)
* master:
- Worker raised notices are printed a single time by the manager now.
- Cluster/notices integration cleaned up.
- New tests for cluster/notice integration.
- Notice suppression fixes and tests.
* origin/topic/jsiwek/filter-rotation:
Remove Log::rotation_control (addresses #572).
Add an optional Log::RotationControl to Log::Filter records.
Closes#572.
- The test needed to append the second notice the event queue so that
the notice would be suppressed correctly.
- Setting $suppress_for manually in apply_policy since it doesn't pick
up the &default when directly creating the record inside the NOTICE call.
- Duplicate notices are discovered with the new Notice::Info
field $identifier. It's a string that is left up to the
notice implementor to define which would indicate a
fundamentally duplicate notice. The field is optional and
if it's not included it's not possible for notice
suppression to take place.
- Duplicate notices are suppressed by default for the interval
defined by the Notice::default_suppression_interval variable
(1 hour by default).
- A new notice action was defined ACTION_NO_SUPPRESS to prevent
suppression for a specific notice instance. A convenience set
named not_suppressed_types was also created to not suppress
entire notice types.
- A new field was added to the PolicyItem type to modify the length
of time a notice should be suppressed if the predicate matches.
The field is named $suppress_for. This name makes the code more
readable like this: $suppress_for = 1day
- New events were created to give visibility into the notice
framework's suppression activity.
- event Notice::begin_suppression(n: Notice::Info)
- event Notice::suppressed(n: Notice::Info)
- event Notice::end_suppression(n: Notice::Info)
- The suppression.bro script doesn't have a baseline because
it is causing a segfault in Bro. This one test is the
reason that this is being integrated into a branch instead
of master.
Log rotation is now controlled directly through Filter records.
Also addressed a TODO in the default_path_func regarding the
LogMgr::AddFilter function generating internal filter path
suggestions/fallbacks. Now, if the user doesn't explicitly set a filter
path, the filter's path will be the result of the first call to
default_path_func (happens during the first write to the log). And in
that case the path suggestion argument to the path_func is an empty
string.
- Reorganize top-level 'doc' Makefile target so submodules can easily
add their own doc-generating routines to it. e.g. the Bro project
makes a placeholder 'doc' target, then adds 'restdoc', 'sphinxdoc';
later Broccoli can add it's own target as a dependency for generating
API docs.
- Fixed generated docs for BIFs not being organized under a base/
subdirectory like the original source files.
- Fixed documentation style for function parameters not applying to
functions declared as record fields.
- Misc. script documentation tweaks to address warnings given by Sphinx.
* origin/topic/gilbert/ascii-header:
Updated tests; removed net type from type conversion code.
Updated header format (see #558)
Header modification to LogWriterAscii to make it easier for scripts to understand bro log files.
Notes:
- I've refactored the code a bit, also adapting the style a bit.
Also edited the header format slightly.
- I'm skipping the testing/btest/profiles directory, which seems
unrelated.
- I'm also skipping the baseline updates as they weren't
up-to-date anymore. Will update them in a subsequent commit.
- Log path's are generated in the scripting land
now. The default Log stream ID to path string
mapping works like this:
- Notice::LOG -> "notice"
- Notice::POLICY_LOG -> "notice_policy"
- TestModule::LOG -> "test_module"
- Logging streams updated across all of the shipped
scripts to be more user friendly. Instead of
the logging stream ID HTTP::HTTP, we now have
HTTP::LOG, etc.
- The priorities on some bro_init handlers have
been adjusted to make the process of applying
filters or disabling streams easier for users.
This allows for the RotationControl to be automatically added to the
Log::rotation_control table for the filter's (writer, path) when it is
added to a stream via Log::add_filter. Log::remove_filter now also
removes any RotationControl's associated with the filter from the
Log::rotation_control table.
This can be used from a Bro script to cause Bro to exit with non-zero
status and a message to stderr. Uses of the exit() BIF in scripts
for terminating Bro because of an error were replaced with this one,
which addresses #564.
- Since each host in a cluster has it's own view of the metrics
the only time the manager would get a chance for a global view
is the break_interval. This update improves that time. If a
worker crosses 10% of the full threshold, it will send it's
value to the manager which can then ask the rest of the cluster
for a global view. The manager then adds all of the values for
each workers metric indexes together and will do the notice
if it crosses the threshold so that it isn't dependent on
waiting for the break interval to hit. This functionality
works completely independently of the break_interval too. Logging
will happen as normal.
- Small update for SSH bruteforcer detection to match additions in
the metrics framework API.
- The hope is that this update is mostly invisible from anyone's
perspective. The only affect it should have on users is to better
the detection of metric values crossing thresholds on cluster
deployments.
- fixing some Metrics::add_data() call signatures
- slight refactors to cluster framework @if and adding a NONE NodeType for
so local_node_type() will return that instead of just emitting an error
when cluster mode isn't enabled
- `make restdoc` target now uses bro's bare-mode
- bro scripts generated from bifs now really only live in the build/src/base/
directory and changed the DocSourcesList.cmake to dynamically figure out
what bifs exist by looking in src/ instead of build/src/
- add some missing @load dependencies
- Metrics now work on cluster deployments with no caveats. It should be
completely transparent. Intermediate updates to speed some detection
will come later.
* origin/topic/jsiwek/autodoc-fixes:
Update doc sources and touch up a few script comments.
Fixes for script auto-documentation.
Conflicts:
scripts/base/frameworks/logging/main.bro
- New ACTION_ADD_GEODATA to add geodata to notices in an extension
field named remote_location.
- Loading extend-email/hostnames by default now that it only
does anything when the ACTION_EMAIL action is applied (finally).
