This PR changes the way in which the SSL analyzer tracks the direction of connections. So far, the SSL analyzer assumed that the originator of a connection would send the client hello (and other associated client-side events), and that the responder would be the SSL servers. In some circumstances this is not true, and the initiator of a connection is the server, with the responder being the client. So far this confused some of the internal statekeeping logic and could lead to mis-parsing of extensions. This reversal of roles can happen in DTLS, if a connection uses STUN - and potentially in some StartTLS protocols. This PR tracks the direction of a TLS connection using the hello request, client hello and server hello handshake messages. Furthermore, it changes the SSL events from providing is_orig to providing is_client, where is_client is true for the client_side of a connection. Since the argument positioning in the event has not changed, old scripts will continue to work seamlessly - the new semantics are what everyone writing SSL scripts will have expected in any case. There is a new event that is raised when a connection is flipped. A weird is raised if a flip happens repeatedly. Addresses GH-2198. |

This directory contains suites for testing for Zeek's correct
operation:
btest/
An ever-growing set of small unit tests testing Zeek's
functionality.
external/
A framework for downloading additional test sets that run more
complex Zeek configuration on larger traces files. Due to their
size, these are not included directly. See the README for more
information.
scripts/
Helpers scripts used by some tests.
