- Unserializing files that were previously kicked out of the open-file
cache would cause them to be fopen'd with the original access
permissions which is usually 'w' and causes truncation. They
are now opened in 'a' mode. (addresses #780)
- Add 'max_files_in_cache' script option to manually set the maximum
amount of opened files to keep cached. Mainly this just helped
to create a simple test case for the above change.
- Remove unused NO_HAVE_SETRLIMIT preprocessor switch.
- On systems that don't enforce a limit on number of files opened for
the process, raise default max size of open-file cache from
32 to 512.
- SSL related files and classes renamed to remove the "binpac" term.
- A small fix for DPD scripts to make the DPD log more helpful if
there are multiple continued failures. Also, fixed the SSL
analyzer to make it stop doing repeated violation messages for
some handshake failures.
- Added a $issuer_subject to the SSL log.
- Created a basic test for SSL.
conn.log now sets a field indicating all the parent tunnel UIDs over
which a connection operated and cross reference the UIDs found in
the tunnel.log.
Also some renaming of tunnel related types at the scripting layer.
- Packet loss interval changed to 5 minutes by default. Users
were getting too many notices from this.
- BPF load balancing (ipv4 and ipv6). This will tie in with
upcoming BroControl support for configuring this.
- BPF based connection sampling.
- Small improvements to how and when filters are installed.
* origin/topic/dnthayer/bug801:
Added an option to specify the 'etc' directory
Closes#801.
Note, I've adapted the code in configure a bit to make it independent
of the argument order (same for an older option). Hope that works ...
- AYIYA works.
- AYIYA analyzed connections are still labelled wrong in conn.log (logged as syslog)
- Some clean up for left over code.
- Small refactoring to pass packets back from analyzers to core.
- $uid is now optional in conn logs since ip-in-ip tunnel parent's
won't have an actual connection.
UDP tunnel support removed for now, to be re-added in specific
analyzers later, but IP-in-IP is now decapsulated recursively
so nested tunnels can be seen and the inner packets get sent
through the IP fragment reassembler if necessary.

Just trying to bring topic/gregor/tunnel up to date in this new branch.
Compiles, but untested.
- The 'icmp_conn' record now contains an 'hlim' field since hop limit
in the IP header is an interesting field for at least these ND
messages.
- Changed 'icmp_router_advertisement' event parameters.
'router_lifetime' is now an interval. Fix 'reachable_time' and
'retrans_timer' using wrong internal Val type for intervals.
Made more of the known router advertisement flags available through
boolean parameters.
- Changed 'icmp_neighbor_advertisement' event parameters to add
more of the known boolean flags.
* origin/topic/icmp6:
Fixes for IPv6 truncation and ICMP/ICMP6 analysis.
Change ICMPv6 checksum calculation to use IP_Hdr wrapper.
Update IPv6 atomic fragment unit test to filter output of ICMPv6.
Add more data to icmp events
More code cleanup
Add more icmpv6 events, and general code cleanup
Fix compile failure after merge from master
Significant edit pass over ICMPv6 code.
Porting Matti's branch to git.
Closes#808.
