Removing a stray printf from RDP analyzer.
Another big RDP update.
New script to add a field to rdp.log when the connection is upgraded to SSL.
Huge updates to the RDP analyzer from Josh Liburdi.
FreeRDP test trace showing SSL encryption -- RDP analyzer does not currently handle this and SSL analyzer does not identify it either
Wireshark test trace for native encryption -- generates a binpac error
Delete RDP-004.pcap
Delete nla_win7_win2k8r2.pcap
Update dpd.sig
Fixed typo
Added check for connection existence

BIT-1340 #merged
- Some scripts used wrong SSH module/namespace scoping on events.
- Fix outdated notice documentation related to SSH password guessing.
- Add a unit test for SSH pasword guessing notice.
I replaced a few strcmps with either calls to std::str.compare
or with the == operator of BroString.
Also changed two of the input framework tests that did not pass
anymore after the merge. The new SSH analyzer no longer loads the
scripts that let network time run, hence those tests failed because
updates were not propagated from the threads (that took a while
to find.)

BIT-1344: #merged
This allows the path for the default filter to be specified explicitly
when creating a stream and reduces the need to rely on the default path
function to magically supply the path.
The default path function is now only used if, when a filter is added to
a stream, it has neither a path nor a path function already.
Adapted the existing Log::create_stream calls to explicitly specify a
path value.
Addresses BIT-1324
* origin/topic/johanna/cert-validation:
and still use the hash for notice suppression.
add knob to revert to old validation behavior
Update certificate validation script - new version will cache valid intermediate chains that it encounters on the wire and use those to try to validate chains that might be missing intermediate certificates.
BIT-1332 #merged
intermediate chains that it encounters on the wire and use those to try
to validate chains that might be missing intermediate certificates.
This vastly improves the number of certificates that Bro can validate.
The only drawback is that now validation behavior is not entirely
predictable anymore - the certificate of a server can fail to validate
when Bro just started up (due to the intermediate missing), and succeed
later, when the intermediate can be found in the cache.
Has been tested on big-ish clusters and should not introduce any
performance problems.
* origin/topic/johanna/x509-cn:
Use our new features to send the CN and SAN fields of certificates to the intel framework.
Do not log common name by default (it is most interesting for scripts) and add a test case.
extract most specific common name from certificates
BIT-1323 #merged
* origin/topic/johanna/ssl-policy:
Extend the weak-keys policy file to also alert when encountering ssl connections with old versions as well as unsafe cipher suites.
BIT-1321 #merged
ssl connections with old versions as well as unsafe cipher suites.
Also make the notice suppression handling of other ssl policy files
a tad more robust.
Fixing one missing index adjustment (I believe ...)
BIT-757 #merged
* origin/topic/jsiwek/deprecation:
Fix typo.
Update documentation (broken links, outdated tests).
Update NEWS for deprecated/changed functions.
Deprecate split* family of BIFs.
Improve use of &deprecated on functions.
Add a new attribute: &deprecated.
These functions are now deprecated in favor of alternative versions that
return a vector of strings rather than a table of strings.
Deprecated functions:
- split: use split_string instead.
- split1: use split_string1 instead.
- split_all: use split_string_all instead.
- split_n: use split_string_n instead.
- cat_string_array: see join_string_vec instead.
- cat_string_array_n: see join_string_vec instead.
- join_string_array: see join_string_vec instead.
- sort_string_array: use sort instead instead.
- find_ip_addresses: use extract_ip_addresses instead.
Changed functions:
- has_valid_octets: uses a string_vec parameter instead of string_array.
Addresses BIT-924, BIT-757.
* origin/fastpath:
for dh key exchanges, use p as the parameter for weak key exchanges. Y can be a few bytes smaller due to the modulo operation - this is ok.
* origin/topic/vladg/mysql:
Update baselines.
Fix a logic bug with handling quits after the cleanup.
Integrate MySQL with the software framework
A bit of MySQL cleanup - removed unused events, consolidated similar events, fixed up main.bro a bit
Move MySQL analyzer to the new plugin architecture.
Add a btest for the Wireshark sample MySQL PCAP
Add support for more commands, and support quit
Redo the response handling..
Whitespace/readability fixes.
Add memleak and auth btests.
Update baselines.
Get MySQL to compile and add basic v9 support.
MySQL analyzer
* origin/fastpath:
last ssl fixes - missed three more.
and more tiny ssl script fixes
a few more small fixes for chains containing broken certs.
fix expression errors in x509 policy scrips when unparseable data is in certificate chain.
Good stuff! (but I admit I didn't look at the OpenSSL code too closely :)
* origin/topic/bernhard/even-more-ssl-changes:
small test update & script fix
update baselines & add ocsp leak check
Add policy script adding ocsp validation to ssl.log
Implement verification of OCSP replies.
Add tls flag to smtp.log. Will be set if a connection switched to startls.
add starttls support for pop3
Add smtp starttls support
Replace errors when parsing x509 certs with weirds (as requested by Seth).
move tls content types from heartbleed to consts.bro. Seems better to put them there...
Add new features from other branch to the heartbleed-detector (and clean them up).
Let TLS analyzer fail better when no longer in sync with the data stream. The version field in each record-layer packet is now re-checked.
