- This fixes BIT-1769 by logging all requests even in the absence of a
reply. The way that request and replying matching were being handled
was restructured to mostly ignore the transaction ids because they
aren't that helpful for network monitoring and it makes the script
structure more complicated.
- Add `framed_addr` field to the radius log to indicate if the radius
server is hinting at an address for the client.
- Add `ttl` field to indicate how quickly the radius server is replying
to the network access server.
- Fix a bunch of indentation inconsistencies.
This is a small caveat to this implementation. The ethernet
header that is carried over the tunnel is ignored. If a user
tries to do MAC address logging, it will only show the MAC
addresses for the outer tunnel and the inner MAC addresses
will be stripped and not available anywhere.
If connection flipping occured in Sessions.cc code (invoked e.g. when
the original SYN is missing), layer 2 flipping was not performed. This
change switches to always use the connection flipping code in Conn.cc
which performs the switch correctly.
- New fields: extracted_cutoff and extracted_size.
These fields will be null if the file isn't extracted.
- Extended the extraction test to test the files log too.

Updates for SMB auth handling from Martin van Hensbergen.
BIT-1721 #merged
SMB error handling improved. The analyzer isn't destroyed when a problem
is encoutered anymore. The flowbuffer in the parser is now flushed and
the analyzer is set to resync against an SMB command. This was needed
because there is some state about open files that is kept within the
parser itself which was being destroyed and that was causing analysis
after content gaps or parse errors to be faulty. The new mechanism
doesn't detroy the parser so parsing after gaps is improved.
DCE_RPC handling in SMB is improved in the edge case where a drive
mapping isn't seen. There is a new const named SMB::pipe_filenames
which is used as a heuristic for identifying "files" opened on named
pipe shares. If the share mapping type isn't known and a filename
in this set is found, the share type will change to "PIPE" by
generating an event named "smb_pipe_connect_heuristic". Reads and
writes to that file will be sent to the DCE_RPC analyzer instead of
to the files framework.
The concept of "unknown" share types has been removed due to the new
heuristic detection of share types.
Some general clean up of how the SMB cmd log is written and when.
* 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.
BIT-1641 #merged
Filter out the python 2 "L" suffix on long integers (not valid in Python 3),
and change python 3 "object at" to "instance at" when printing
class instances.
