Siwek, Corelight)
* Remove unused BroObj::in_ser_cache member. (Jon Siwek, Corelight)
2.6-612 | 2019-07-15 19:46:04 -0700
* Fix a potential usage of List::remove_nth(-1) (Jon Siwek, Corelight)
* Change List::remote(const T&) to return a bool (Jon Siwek, Corelight)
It now indicates whether the removal took place or not, depending
on whether a matching element was found in the list.
* Fix debug build due to old int_list usage within assert (Jon Siwek, Corelight)
* Convert uses of loop_over_list to ranged-for loops (Tim Wojtulewicz, Corelight)
* Remove loop_over_queue (as an example for later removing loop_over_list) (Tim Wojtulewicz, Corelight)

2.6-595 | 2019-07-12 13:34:08 -0700
* GH-157: Mark some attributes as not allowed for global variables (Tim Wojtulewicz, Corelight)
This disallows &default for global values that are not tables, and &optional for all globals.
* Fix uncaught exceptions from Val cloning failures (Jon Siwek, Corelight)
2.6-591 | 2019-07-11 13:29:28 -0700
* Fix potential thread safety issue with zeekenv util function
Observed segfault accessing the local static std::map of zeekenv() from
a logging thread, but only in non-debug builds using Apple/Clang
compiler, not in a debug build or GCC. Don't quite get this behavior
since static local variable initialization is supposed to be thread-safe
since C++11, but moving to a global static works and is "more efficient"
anyway since there's no longer any run-time overhead. (Jon Siwek, Corelight)
2.6-589 | 2019-07-11 13:14:52 -0700

* Convert all JSON output to use an external library for better consistency (Tim Wojtulewicz, Corelight)
See NEWS for more details; this makes to_json a bif and causes slight changes in its
output, as well as the output of the JSON logger.
2.6-576 | 2019-07-10 18:38:54 -0700
* Remove unused option: chunked_io_buffer_soft_cap (Jon Siwek, Corelight)

* Fix CIF integration and add logging options to intel.log and added comments to code (sfinlon)
2.6-558 | 2019-07-01 01:27:50 -0700
* GH-443: fix uses of timestamp 0 in cluster diagnostic logs
For broker.log and cluster.log: there was a race condition. A worker's
first IOSource that it processes is potentially Broker if there were
no packets available yet and thread scheduling happens to work out
such that network connections (inside CAF threads) become established
before we enter the main I/O loop. Such peering establishments would
generate logs with timestamp 0 as there was not yet any code path
taken that would update network_time.
For reporter.log: any non-worker (packet-processing) node would just
unnecessarily use a timestamp of 0 for their reporter messages. (Jon Siwek, Corelight)

* Un-deprecate file rotation functions
- rotate_file
- rotate_file_by_name
- calc_next_rotate
These still have use-cases even though no longer used for our logging
functionality. E.g. rotate_file_by_name may be used to rotate
pcap dump files.
Also the log_rotate_base_time option was marked deprecated, but still
used in the new logging framework. (Jon Siwek, Corelight)
* Switch default CAF scheduler policy to work sharing
It may generally be better for our default use-case, as workers may
save a few percent cpu utilization as this policy does not have to
use any polling like the stealing policy does.
This also helps avoid a potential issue with the implementation of
spinlocks used in the work-stealing policy in current CAF versions,
where there's some conditions where lock contention causes a thread
to spin for long periods without relinquishing the cpu to others. (Jon Siwek, Corelight)
* Update sqlite to 3.28.0. (Johanna Amann, Corelight)
* GH-320: Improve RFB (VNC) protocol parsing
Parsing now stops for both client and server if either encounters
any parsing error or invalid state.
After a complete handshake, server messages are no longer parsed.
Support for that is incomplete and not sure it's that useful anyway
since it mostly contains pixel data. (Jon Siwek, Corelight)
2.6-536 | 2019-06-28 12:10:55 -0700
* Add Windows Minidump file signature (Alexander Bolshakov)
2.6-534 | 2019-06-28 11:48:41 -0700
* Change notices to be processed on worker. (Johanna Amann, Corelight)
In the past they were processed on the manager - which requires big
records to be sent around.
This has a potential of incompatibilities if someone relied on global
state for notice processing.
Also may prevent notice de-duplication due to expected race
condition of suppression messages taking time to proaogate out
to all cluster nodes.
2.6-531 | 2019-06-27 12:09:08 -0700
* GH-375: Remove the BroFile cache (Johanna Amann, Corelight)
2.6-529 | 2019-06-27 10:12:34 -0700
* Fix creating a StringVal from std::string. (Johanna Amann, Corelight)
Currently, creating a StringVal from a std::string did not work with
data that contains \0 characters. This easy fix changes this - and
should also lead to a small speed increase for code using this
constructor.
This obviously means that more data might copied now in some cases that
were previously cut off at the first 0-byte. Our test-suite did not
reveal any such cases.
2.6-526 | 2019-06-25 12:45:31 -0700
* Make a paraglob unit test parallelizable (Jon Siwek, Corelight)
2.6-523 | 2019-06-25 10:38:24 -0700
* GH-427: improve default ID values shown by Zeekygen
The default value of an ID is now truly the one used to initialize it,
unaltered by any subsequent redefs.
Redefs are now shown separately, along with the expression that
modifies the ID's value. (Jon Siwek, Corelight)
* Unbreak build on Linux (Johanna Amann, Corelight)
2.6-519 | 2019-06-24 15:25:08 -0700
* GH-435: fix null pointer deref in RPC analyzer. (Jon Siwek, Corelight)
2.6-517 | 2019-06-24 15:20:39 -0700
* Add paraglob, a fairly quick data structure for matching a string against a large list of patterns.
(Zeke Medley, Corelight)
* GH-171: support warning messages alongside deprecated attributes (Tim Wojtulewicz, Corelight)
2.6-503 | 2019-06-21 11:17:58 -0700
* GH-417: Remove old, unmaintained p0f support. (Johanna Amann, Corelight)
2.6-500 | 2019-06-20 20:54:15 -0700
* Add new RDP event: rdp_client_cluster_data (Jeff Atkinson)
* Added "options" field to RDP::ClientChannelDef (Jeff Atkinson)
2.6-494 | 2019-06-20 20:24:38 -0700
* Renaming src/StateAccess.{h,cc} to src/Notifier.{h,cc}.
The old names did not reflect the content of the files anymore. (Robin Sommer, Corelight)
* Remove MutableVal, StateAccess classes, enum Opcode. (Robin Sommer, Corelight)
* Redo API for notifiers.
There's now an notifier::Modifiable interface class that class
supposed to signal modifications are to be derived from. This takes
the place of the former MutableValue class and also unifies how Val
and IDs signal modifications. (Robin Sommer, Corelight)
* Redo NotfifierRegistry to no longer rely on StateAccess.
We simplify the API to a simple Modified() operation. (Robin Sommer, Corelight)
* Add new test for when-statement watching global variables. (Robin Sommer, Corelight)
2.6-482 | 2019-06-20 19:57:20 -0700
* Make configure complain if submodules are not checked out. (Johanna Amann, Corelight)
* Improve C++ header includes to improve build time (Jon Siwek, Corelight)
2.6-479 | 2019-06-20 18:31:58 -0700
* Fix TableVal::DoClone to use CloneState cache (Jon Siwek, Corelight)
2.6-478 | 2019-06-20 14:19:11 -0700
* Remove old Broccoli SSL options (Jon Siwek, Corelight)
- ssl_ca_certificate
- ssl_private_key
- ssl_passphrase
2.6-477 | 2019-06-20 14:00:22 -0700
* Remove unused SerialInfo.h and SerialTypes.h headers (Jon Siwek, Corelight)
2.6-476 | 2019-06-20 13:23:22 -0700
* Remove opaque of ocsp_resp. (Johanna Amann, Corelight)
Only used in one event, without any way to use the opaque for anything
else. At this point this just seems like a complication that has no
reason to be there.
* Remove remnants of event serializer. (Johanna Amann, Corelight)
* Reimplement serialization infrastructure for OpaqueVals.
(Robin Sommer, Corelight & Johanna Amann, Corelight)
We need this to sender through Broker, and we also leverage it for
cloning opaques. The serialization methods now produce Broker data
instances directly, and no longer go through the binary formatter.
Summary of the new API for types derived from OpaqueVal:
- Add DECLARE_OPAQUE_VALUE(<class>) to the class declaration
- Add IMPLEMENT_OPAQUE_VALUE(<class>) to the class' implementation file
- Implement these two methods (which are declated by the 1st macro):
- broker::data DoSerialize() const
- bool DoUnserialize(const broker::data& data)
This machinery should work correctly from dynamic plugins as well.
OpaqueVal provides a default implementation of DoClone() as well that
goes through serialization. Derived classes can provide a more
efficient version if they want.
The declaration of the "OpaqueVal" class has moved into the header
file "OpaqueVal.h", along with the new serialization infrastructure.
This is breaking existing code that relies on the location, but
because the API is changing anyways that seems fine.
* Implement a Shallow Clone operation for types. (Johanna Amann, Corelight)
This is needed to track name changes for the documentation.
* Remove old serialization infrastrucutre. (Johanna Amann, Corelight)
2.6-454 | 2019-06-19 09:39:06 -0700
* GH-393: Add slice notation for vectors (Tim Wojtulewicz, Corelight & Jon Siwek, Corelight)
Example Syntax:
local v = vector(1, 2, 3, 4, 5);
v[2:4] = vector(6, 7, 8); # v is now [1, 2, 6, 7, 8, 5]
print v[:4]; # prints [1, 2, 6, 7]

2.6-404 | 2019-06-12 15:10:19 -0700
* Rename directories from bro to zeek (Daniel Thayer)
The new default installation prefix is /usr/local/zeek
2.6-400 | 2019-06-07 20:06:33 -0700
* Adapt bro_plugin CMake macros to use zeek_plugin (Jon Siwek, Corelight)
2.6-399 | 2019-06-07 14:02:18 -0700
* Update SSL documentation. (Johanna Amann)
* Support the newer TLS 1.3 key_share extension. (Johanna Amann)
* Include all data of the server-hello random (Johanna Amann)
Before we cut the first 4 bytes, which makes it impossible to recognize
several newer packets (like the hello retry).
* Parse TLS 1.3 pre-shared-key extension. (Johanna Amann)
Adds new events:
- ssl_extension_pre_shared_key_client_hello
- ssl_extension_pre_shared_key_server_hello
2.6-391 | 2019-06-07 17:29:28 +1000

2.6-378 | 2019-06-05 16:23:04 -0700
* Rename BRO_DEPRECATED macro to ZEEK_DEPRECATED (Jon Siwek, Corelight)
2.6-377 | 2019-06-05 16:15:58 -0700
* Deprecate functions with "bro" in them. (Jon Siwek, Corelight)
* "bro_is_terminating" is now "zeek_is_terminating"
* "bro_version" is now "zeek_version"
The old functions still exist for now, but are deprecated.
2.6-376 | 2019-06-05 13:29:57 -0700
* GH-379: move catch-and-release and unified2 scripts to policy/ (Jon Siwek, Corelight)
These are no longer loaded by default due to the performance impact they
cause simply by being loaded (they have event handlers for commonly
generated events) and they aren't generally useful enough to justify it.
2.6-375 | 2019-06-04 19:28:06 -0700
* Simplify threading::Value destructor (Jon Siwek, Corelight)
* Add pattern support to input framework. (Zeke Medley, Corelight)
2.6-369 | 2019-06-04 17:53:10 -0700
* GH-155: Improve coercion of expression lists to vector types (Tim Wojtulewicz, Corelight)
* GH-159: Allow coercion of numeric record field values to other types (Tim Wojtulewicz, Corelight)
* Allow passing a location to BroObj::Warning and BroObj::Error. (Tim Wojtulewicz, Corelight)
This allows callers (such as check_and_promote) to pass an expression
location to be logged if the location doesn't exist in the value being
promoted.
* Add CLion directories to gitignore (Tim Wojtulewicz, Corelight)
* Move #define outside of max_type for clarity (Tim Wojtulewicz, Corelight)
2.6-361 | 2019-06-04 10:30:21 -0700
* GH-293: Protect copy() against reference cycles. (Robin Sommer, Corelight)
Reference cycles shouldn't occur but there's nothing really preventing
people from creating them, so may just as well be safe and deal with
them when cloning values.
2.6-359 | 2019-05-31 13:37:17 -0700
* Remove old documentation reference to rotate_interval (Jon Siwek, Corelight)
2.6-357 | 2019-05-30 10:57:54 -0700
* Tweak to ASCII reader warning suppression (Christian Kreibich, Corelight)
Warnings in the ASCII reader so far remained suppressed even
when an input file changed. It's helpful to learn about problems
in the data when putting in place new data files, so this change
maintains the existing warning suppression while processing a file,
but re-enables warnings after updates to a file.
2.6-354 | 2019-05-29 09:46:19 -0700
* Add weird: "RDP_channels_requested_exceeds_max" (Vlad Grigorescu)
2.6-352 | 2019-05-28 17:57:36 -0700
* Reduce data copying in Broker message processing (Jon Siwek, Corelight)
* Improve Broker I/O loop integration: less mutex locking (Jon Siwek, Corelight)
Checking a subscriber for available messages required locking a mutex,
but we should never actually need to do that in the main-loop to check
for Broker readiness since we can rely on file descriptor polling.
* Improve processing of broker data store responses (Jon Siwek, Corelight)
Now retrieves and processes all N available responses at once instead
of one-by-one-until-empty.
2.6-345 | 2019-05-28 11:32:16 -0700
* RDP: Add parsing and logging of channels requested by the client. (Vlad Grigorescu)
Can determine capabilities requested by the client, as well as attacks such
as CVE-2019-0708.
2.6-342 | 2019-05-28 10:48:37 -0700
* GH-168: Improve type-checking for table/set list assignment. (Zeke Medley and Jon Siwek, Corelight)
2.6-340 | 2019-05-24 18:02:43 -0700
* Add support for parsing additional DHCP options (Jay Wren)
The following optional fields were added to the DHCP::Options record:
- time_offset (Option 2)
- time_servers (Option 4)
- name_servers (Option 5)
- ntp_servers (Option 42)
2.6-338 | 2019-05-24 17:06:08 -0700
* Add input file name to additional ASCII reader warning messages (Christian Kreibich, Corelight)
2.6-336 | 2019-05-24 10:23:20 -0700
* GH-378: check validity of missing 'val' field in Input::add_table (Jon Siwek, Corelight)
2.6-335 | 2019-05-24 08:58:59 -0700
* Fix memory leak when no protocol_violation event handler exists (Jon Siwek, Corelight)
2.6-334 | 2019-05-23 20:40:03 -0700
* Add an internal getenv wrapper function: zeekenv (Jon Siwek, Corelight)
It maps newer environment variable names starting with ZEEK to the
legacy names starting with BRO.
* Rename all BRO-prefixed environment variables (Daniel Thayer)
For backward compatibility when reading values, we first check
the ZEEK-prefixed value, and if not set, then check the corresponding
BRO-prefixed value.
2.6-331 | 2019-05-23 18:03:42 -0700
* Update broker unit test output. (Jon Siwek, Corelight)
Due to string representation of Broker vectors changing (they now
use parentheses instead of square brackets).
2.6-330 | 2019-05-23 13:04:26 -0700
* GH-173: Support ranges of values for value_list elements in the signature parser
(Tim Wojtulewicz, Corelight)
* GH-173: Modify the signature parser so ID components can't start with numbers
(Tim Wojtulewicz, Corelight)
2.6-327 | 2019-05-23 11:56:11 -0700
* Remove redundant RecordVal::record_type member (Jon Siwek, Corelight)
2.6-326 | 2019-05-23 10:49:38 -0700
* Fix parse-time RecordVal tracking containing duplicates (Jon Siwek, Corelight)
2.6-325 | 2019-05-22 23:56:23 -0700
* Add leak-checks for new copy operations (Johanna Amann, Corelight)
* Finish implementation of new copy method. (Johanna Amann, Corelight)
All types (besides EntropyVal) now support a native copy operation,
which uses primitives of the underlying datatypes to perform a quick
copy, without serialization.
EntropyVal is the one exception - since that type is rather complex
(many members) and will probably not be copied a lot, if at all, it
makes sense to just use the serialization function.
This will have to be slightly re-written in the near-term-future to use
the new serialization function for that opaque type.
This change also introduces a new x509_from_der bif, which allows to
parse a der into an opaque of x509.
This change removes the d2i_X509_ wrapper function; this was a remnant
when d2i_X509 took non-const arguments. We directly use d2i_X509 at
several places assuming const-ness, so there does not seem to ba a
reason to keep the wrapper.
This change also exposed a problem in the File cache - cases in which an
object was brought back into the cache, and writing occurred in the
file_open event were never correctly handeled as far as I can tell.
* Reimplement copy(). (Robin Sommer, Corelight)
The old implementation used the serialization framework, which is
going away. This is a new standalone implementation that should also
be quite a bit faster.
2.6-318 | 2019-05-21 09:17:53 -0700
* Remove state_dir and state_write_delay options (Jon Siwek, Corelight)
* Remove a reference to &synchronized from docs (Jon Siwek, Corelight)
2.6-316 | 2019-05-20 20:56:46 -0700
* Additional Bro to Zeek renaming (Daniel Thayer)
* Added a new unit test for legacy Bro Plugins (Daniel Thayer)
* Added a symlink bro-path-dev.in for use by legacy Bro packages (Daniel Thayer)
2.6-314 | 2019-05-20 16:20:33 -0700
* Remove deprecated attributes. (Johanna Amann, Corelight)
To be more exact: &encrypt, &mergeable, &rotate_interval, &rotate_size
Also removes no longer used redef-able constants:
log_rotate_interval, log_max_size, log_encryption_key
2.6-311 | 2019-05-20 09:07:58 -0700
* Add missing &optional attr to KRB record fields; also add existence
checks to scripts (Jon Siwek, Corelight).
2.6-308 | 2019-05-17 14:13:46 -0700
* Always emit scripting errors to stderr during zeek_init (Jon Siwek, Corelight)
2.6-307 | 2019-05-16 13:37:24 -0700

2.6-300 | 2019-05-15 09:00:57 -0700
* Fixes to DNS lookup, including ref-counting bugs, preventing starvation
of the DNS_Mgr in the I/O loop, dead code removal, and a fix that
prevents the timeout of already resolved DNS lookups (Jon Siwek, Corelight)
2.6-292 | 2019-05-14 19:01:05 -0700
* Fix maybe-uninitialized compiler warning (Jon Siwek, Corelight)
2.6-290 | 2019-05-14 18:35:25 -0700
* Update btest.cfg path to use zeek-aux (Jon Siwek, Corelight)
2.6-288 | 2019-05-14 17:47:55 -0700
* Update CMake to use aux/zeekctl and aux/zeek-aux submodules (Jon Siwek, Corelight)
2.6-287 | 2019-05-14 17:40:40 -0700
* Rename broctl submodule to zeekctl (Jon Siwek, Corelight)
2.6-286 | 2019-05-14 13:19:12 -0700
* Undo an unintentional change to btest.cfg from a recent commit (Daniel Thayer)
* Fix zeek-wrapper and improve error messages (Daniel Thayer)
The script was not passing command-line arguments to the new program.
* Update for renaming BroControl to ZeekControl. (Robin Sommer, Corelight)
* GH-239: Rename bro to zeek, bro-config to zeek-config, and bro-path-dev to zeek-path-dev.
(Robin Sommer, Corelight)
This also installs symlinks from "zeek" and "bro-config" to a wrapper
script that prints a deprecation warning.
2.6-279 | 2019-05-13 20:02:59 -0700
* GH-365: improve un-indexable type error message (Jon Siwek, Corelight)
2.6-277 | 2019-05-08 12:42:18 -0700
* Allow tuning Broker log batching via scripts (Jon Siwek, Corelight)
Via redefining "Broker::log_batch_size" or "Broker::log_batch_interval"
2.6-276 | 2019-05-08 09:03:27 -0700
* Force the Broker IOSource to idle periodically, preventing packet
IOSource starvation. (Jon Siwek, Corelight).
2.6-274 | 2019-05-08 08:58:25 -0700
* GH-353: Add `/<re>/i` case-insensitive signature syntax (Jon Siwek, Corelight)
2.6-272 | 2019-05-06 18:43:13 -0700
* Remove support for using && and || with patterns. (Johanna Amann, Corelight)
This was never documented and previously deprecated.
* Remove RemoteSerializer and related code/types. (Johanna Amann, Corelight)
Also removes broccoli from the source tree.
* Remove PersistenceSerializer. (Johanna Amann, Corelight)
* Remove &synchronized and &persistent attributes. (Johanna Amann, Corelight)
2.6-264 | 2019-05-03 11:16:38 -0700
* Fix sporadic openflow/broker test failure (Jon Siwek, Corelight)
2.6-263 | 2019-05-02 22:49:40 -0700
* Install local.zeek as symlink to pre-existing local.bro (Jon Siwek, Corelight)
This a convenience for those that are upgrading. If we didn't do
this, then deployments can silently break until the user intervenes
since BroControl now prefers to load the initially-vanilla local.zeek
instead of the formerly-customized local.bro.
2.6-262 | 2019-05-02 21:39:01 -0700
* Rename Zeexygen to Zeekygen (Jon Siwek, Corelight)
2.6-261 | 2019-05-02 20:49:23 -0700
* Remove previously deprecated policy/protocols/smb/__load__ (Jon Siwek, Corelight)
2.6-260 | 2019-05-02 19:16:48 -0700
* GH-243: Remove deprecated functions/events from 2.6 and earlier (Johanna Amann, Corelight)
2.6-258 | 2019-05-02 12:26:54 -0700
* GH-340: Improve IPv4/IPv6 regexes, extraction, and validity functions.
is_valid_ip() is not a BIF, the IP regular expressions are improved and
extract_ip_addresses should give better results due to this.
(Jon Siwek, Corelight)
2.6-255 | 2019-05-01 08:38:49 -0700
* Add methods to queue events without handler existence check
Added ConnectionEventFast() and QueueEventFast() methods to avoid
redundant event handler existence checks.
It's common practice for caller to already check for event handler
existence before doing all the work of constructing the arguments, so
it's desirable to not have to check for existence again.
E.g. going through ConnectionEvent() means 3 existence checks:
one you do yourself before calling it, one in ConnectionEvent(), and then
another in QueueEvent().
The existence check itself can be more than a few operations sometimes
as it needs to check a few flags that determine if it's enabled, has
a local body, or has any remote receivers in the old comm. system or
has been flagged as something to publish in the new comm. system. (Jon Siwek, Corelight)
* Cleanup/improve PList usage and Event API
Majority of PLists are now created as automatic/stack objects,
rather than on heap and initialized either with the known-capacity
reserved upfront or directly from an initializer_list (so there's no
wasted slack in the memory that gets allocated for lists containing
a fixed/known number of elements).
Added versions of the ConnectionEvent/QueueEvent methods that take
a val_list by value.
Added a move ctor/assign-operator to Plists to allow passing them
around without having to copy the underlying array of pointers. (Jon Siwek, Corelight)
2.6-250 | 2019-04-29 18:09:29 -0700

* Add 'g' character to conn.log history field to flag content gaps (Vern Paxson, Corelight)
There's also a small change to TCP state machine that distrusts ACKs
appearing at the end of connections (in FIN or RST) such that they won't
count towards revealing a true content gap.
2.6-237 | 2019-04-19 12:00:37 -0700
* GH-236: Add zeek_script_loaded event, deprecate bro_script_loaded (Jon Siwek, Corelight)
Existing handlers for bro_script_loaded automatically alias to the new
zeek_script_loaded event, but emit a deprecation warning.
2.6-236 | 2019-04-19 11:16:35 -0700
* Add zeek_init/zeek_done events and deprecate bro_init/bro_done (Seth Hall, Corelight)
Any existing handlers for bro_init and bro_done will automatically alias
to the new zeek_init and zeek_done events such that code will not break,
but will emit a deprecation warning.

* GH-237: add `@load foo.bro` -> foo.zeek fallback (Jon Siwek, Corelight)
When failing to locate a script with explicit .bro suffix, check for
whether one with a .zeek suffix exists and use it instead.
2.6-225 | 2019-04-16 16:07:49 -0700
* Use .zeek file suffix in unit tests (Jon Siwek, Corelight)

* Rename all scripts to have ".zeek" file extension (Daniel Thayer)
* Add test cases to verify new file extension is recognized (Daniel Thayer)
* Fix the core/load-duplicates.bro test (Daniel Thayer)
* Update script search logic for new .zeek file extension (Daniel Thayer)
When searching for script files, look for both the new and old file
extensions. If a file with ".zeek" can't be found, then search for
a file with ".bro" as a fallback.
* Remove unnecessary ".bro" from @load directives (Daniel Thayer)

- Adds tuning options: SSL::dtls_max_version_errors and
SSL::dtls_max_reported_version_errors
2.6-200 | 2019-04-03 09:44:53 -0700
* Fix reporter net_weird API usage for unknown_mobility_type
(Jon Siwek, Corelight)
* Remove variable content from weird names
This changes many weird names to move non-static content from the
weird name into the "addl" field to help ensure the total number of
weird names is reasonably bounded. Note the net_weird and flow_weird
events do not have an "addl" parameter, so information may no longer
be available in those cases -- to make it available again we'd need
to either (1) define new events that contain such a parameter, or
(2) change net_weird/flow_weird event signature (which is a breaking
change for user-code at the moment).
Also, the generic handling of binpac exceptions for analyzers which
to not otherwise catch and handle them has been changed from a Weird
to a ProtocolViolation.
Finally, a new "file_weird" event has been added for reporting
weirdness found during file analysis. (Jon Siwek, Corelight)
