- The logic for fragment handling has been rewritten and should be correct now.
- There are now tunables for fragment handling overflow situations.
- DCE_RPC::max_cmd_reassembly and DCE_RPC::max_frag_data
- They result in weirds and analyzer removal.
- Memory leak fixed by unique_ptr auto cleanup.
- DCE_RPC is now intolerate of content gaps and will stop
analyzing traffic if content gaps happen (like most other analyzers currently).
* origin/topic/vladg/bit-1641:
Logic fix for ssh/main.bro when the auth status is indeterminate, and fix a test. Addresses BIT-1641.
Clean up the logic for ssh_auth_failed. Addresses BIT-1641
Update baselines for adding a field to ssh.log as part of BIT-1641
Script-land changes for BIT-1641.
Change SSH.cc to use ssh_auth_attempted instead of ssh_auth_failed. Addresses BIT-1641.
Revert "Fixing duplicate SSH authentication failure events."
Create new SSH events ssh_auth_attempt and ssh_auth_result. Add auth_attempts to SSH::Info. Address BIT-1641.
I extended the tests a bit and did some small cleanups. I also moved the
SSH events back to the global namespace for backwards compatibility and
for consistency (the way it was at the moment, some of them were global
some SSH::).
Furthermore, I fixed the ssh_auth_result result event, it was only
raised in the success case. ssh_auth_result is now also checked in the
testcases. I also have a suspicion that the intel integration never
really worked before.

* origin/topic/johanna/tls13:
Better way to deal with overloaded Assign constructors.
A few tabbing fixes in TLS 1.3 support
TLS 1.3 support.
- DCE_RPC fragmentation handling returns!
- Fixed some general parsing issues
- Fixed an issue with the DCE_RPC signature not working for IPv6 connections.
We could actually already see these in traffic with people that use and
enabled them in chrome canary / firefox nightly builds. This change
includes the re-naming of a few names that were never formalli assigned
yet.
* Clean it up, make it more consistent, and add references to similar events.
* Commented out the smb2_set_info_request event, which wasn't being generated.
* Documented the SMB2 record types in init-bare
One more name change: version_num -> version_number
BIT-1707 #merged
* origin/topic/johanna/version:
Slight naming changes for Bro version information.
Add convenient way to access version information to Bro.
With the introduction of the package manager, it will get more common
that applications are able to get information about the currently
running version of Bro. With this commit, scripts can easily compare
which version of Bro they are running.
Commonly, this probably will either look like this (both lines check if
the current Bro version is greater or equal to 2.5)
@if ( Version::num >= 20500 )
or
@if ( Version::greater_equal("2.5") )
Version::info contains detailed information about the running version of
Bro, including beta flags, etc.
Move the when statement to a function so that the connection record is
not in scope. Cloning a connection record is an expensive operation and
this avoids it and this avoids it.
* origin/topic/seth/log-framework-ext:
Log extensions: series of small fixes and new tests.
Change the function for log extension to take a path only and update tests.
Final changes to log framework ext code.
Add logging framework metadata mechanism.
Add unrolling separator & field name map to logging framework.
The extensions now work with optional types, as well with complex types
(like subrecords). Not returning a record in the ext_func no longer
crashes bro.
The default_ext_func was switched to return void in
cases where no extension revord is defined (was bool).
I also got rid of the offsets in the indices - with the rest of the
implementation, that was not really necessary and made the code more
complex.
The "metadata" functionality has been renamed to "ext" to
represent that the logs are being extended. The function that
returns the record which is used to extend the log now receives
a log filter as it's single argument.
The field name "unrolling" is now renamed to "scope" so the variables
names now look like this: "Log::default_scope_sep"
