Changes \x00-\x37 ranges to \x00-\x1f with assumption that the former
was attempting to match ASCII control characters, but mistook an octal
range for hex. This change reduces some false positives.
generate_all_events causes all events to be raised internally; this
makes it possible for dump_events to really capture all events (and not
just those that were handled).
Addresses GH-169
- Use `-b` most everywhere, it will save time.
- Start some intel tests upon the input file being fully read instead of
at an arbitrary time.
- Improve termination condition for some sumstats/cluster tests.
- Filter uninteresting output from some supervisor tests.
- Test for `notice_policy.log` is no longer needed.
Haven't checked different build configurations yet, but all except
a few SumStats tests are stable for me now. The external tests
are also completely failing, but haven't looked at those yet.
- Added test case and adjusted whitespace in merge
* 'stats-logging-fix' of https://github.com/brittanydonowho/zeek:
Fixed stats.zeek to log all data before zeek terminates rather than return too soon
* Generally increase timeouts for tests that have recent transient
failures
* Change any test that relied on `btest-bg-wait -k` since that's never
going to play with with CI systems. Instead, we always need to have
a well-defined termination condition in the test itself (and most
already did, so didn't really need the `-k` flag anyway).
Or otherwise convert into a regular btest if it didn't already seem to
be covered.
There's no need for a separate memory leak test group since compiling
with LeakSanitizer now covers leak checking for the full btest suite.
* 'known_services_multiprotocols' of https://github.com/mauropalumbo75/zeek:
improve logging with broker store
drop services starting with -
remove service from key for Cluster::publish_hrw
remove check for empty services
update tests
order list of services in store key
remove repeated services in logs if already seen
add multiprotocol known_services when Known::use_service_store = T
remove hyphen in front of some services (for example -HTTP, -SSL) In some cases, there is an hyphen before the protocol name in the field connection$service. This can cause problems in known_services and is removed here. It originates probably in some analyzer where it would be better removed in the future.
add multiprotocol known_services when Known::use_service_store = F
Changes during merge:
* whitespace
* add unit test
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.
For backward compatibility when reading values, we first check
the ZEEK-prefixed value, and if not set, then check the corresponding
BRO-prefixed value.
This also installs symlinks from "zeek" and "bro-config" to a wrapper
script that prints a deprecation warning.
The btests pass, but this is still WIP. broctl renaming is still
missing.
#239
* 'master' of https://github.com/hosom/zeek:
Normalize the intel seen filename for smb.
load smb-filenames in scripts/policy/frameworks/intel/seen/__load__.bro
Add SMB::IN_FILE_NAME to Intel::Where enum
Support filenamess for SMB files
I added a test case
The generation of weird events, by default, are now rate-limited
according to these tunable options:
- Weird::sampling_whitelist
- Weird::sampling_threshold
- Weird::sampling_rate
- Weird::sampling_duration
The new get_reporter_stats() BIF also allows one to query the
total number of weirds generated (pre-sampling) which the new
policy/misc/weird-stats.bro script uses periodically to populate
a weird_stats.log.
There's also new reporter BIFs to allow generating weirds from the
script-layer such that they go through the same, internal
rate-limiting/sampling mechanisms:
- Reporter::conn_weird
- Reporter::flow_weird
- Reporter::net_weird
Some of the code was adapted from previous work by Johanna Amann.
Highlights:
- Reduced all DHCP events into a single dhcp_message event. (removed legacy events since they weren't widely used anyway)
- Support many more DHCP options.
- DHCP log is completely reworked and now represents DHCP sessions
based on the transaction ID (and works on clusters).
- Removed the known-devices-and-hostnames script since it's generally
less relevant now with the updated log.
This commit fixes a few small issues.
* server key exchange parameters are only parsed when a named curve is
given.
* I removed the ssl-verbose.bro and moved the functionality into the
testcase.
The information that we get with these events is likely irrelevant to
the majority of Bro users; I do not think that we have to ship a
script that uses them by default. A script like this would be
something to publish via the Bro package manager instead; this is the
approach that we have taken with a number of the recent SSL addition.
* I marked the ssl_server_curve event as deprecated. More information is
contained in the new ssl_ecdh_server_params event.
This is an events that is probably seldomly (or never) directly used
by anyone; I plan to completely remove it right after the 2.6 release.
These were caused by earlier code updates.
This commit also removes the ocsp stapling logging script; it was
defunctional and the information provided by it wnever really has been
especially interesting.
This also rewrites the certificate validation script (which we need for
this) slightly.
This could need a bit of caching, but should generally work very
reliably.
The extension mechanism is basically the one that Seth introduced with
his intel extensions. The main difference lies in using a hook instead
of an event. An example policy implements whitelisting.
The problem is that with certain compilers, the order of the file hash
events is reversed (for at this moment unknown reasons).
This fix simply removes all MD5 events from the dump-events test, only
leaving the SHA1 events. This removes this condition during the test.
