- More data pulled into scriptland.
- Logs expanded with client screen resolution and desired color depth.
- Values in UTF-16 on the wire are converted to UTF-8 before being
sent to scriptland.
- If the RDP turns into SSL records, we now pass data that appears
to be SSL to the PIA analyzer.
- If RDP uses native encryption with X.509 certs we pass those
certs to the files framework and the base scripts pass them forward
to the X.509 analyzer.
- Lots of cleanup and adjustment to fit the documented protocol
a bit better.
- Cleaned up the DPD signatures.
- Moved to flowunit instead of datagram.
- Added tests.
- Re-arrange how some fa_file fields (e.g. source, connection info, mime
type) get updated/set for consistency.
- Add more robust mechanisms for flushing the reassembly buffer.
The goal being to report all gaps and deliveries to file analyzers
regardless of the state of the reassembly buffer at the time it has to
be flushed.
As opposed to delaying until a certain-sized-buffer fills, which is
problematic because then the event becomes out of sync with the "rest of
the world". E.g. content_gap handlers being called sooner than
expected.
Addresses BIT-1240.
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.

* origin/topic/jsiwek/file-signatures:
File type detection changes and fix https.log {orig,resp}_fuids fields.
Various minor changes related to file mime type detection.
Refactor common MIME magic matching code.
Replace libmagic w/ Bro signatures for file MIME type identification.

* origin/topic/bernhard/file-analysis-x509:
Forgot the preamble for the new leak test
(hopefully) last change -> return real opaque vec instead of any_vec
Fix dump-events - it cannot be used with ssl anymore, because openssl does not give the same string results in all versions.
Finishing touches of the x509 file analyzer.
Revert change to only log certificates once per hour.
Change x509 log - now certificates are only logged once per hour.
Fix circular reference problem and a few other small things.
X509 file analyzer nearly done. Verification and most other policy scripts work fine now.
Add verify functionality, including the ability to get the validated chain. This means that it is now possible to get information about the root-certificates that were used to secure a connection.
Second try on the event interface.
Backport crash fix that made it into master with the x509_extension backport from here.
Make x509 certificates an opaque type
rip out x509 code from ssl analyzer. Note that since at the moment the file analyzer does not yet re-populate the info record that means quite a lot of information is simply not available.
parse out extension. One event for general extensions (just returns the openssl-parsed string-value), one event for basicconstraints (is a certificate a CA or not) and one event for subject-alternative-names (only DNS parts).
Very basic file-analyzer for x509 certificates. Mostly ripped from the ssl-analyzer and the topic/bernhard/x509 branch.
* origin/topic/seth/json-formatter:
Updating a couple of tests.
Expanded support for modifying the timestamp format in the JSON formatter.
Ascii input reader now supports all config options per-input stream.
Added an option to the JSON formatter to use ISO 8601 for timestamps.
Refactored formatters and updated the the writers a bit.
Includes some minor bugfixes and cleanup at various places, including
in old code.
