Internally, all BROv6 preprocessor switches were removed and
addr/subnet representations wrapped in the new IPAddr/IPPrefix classes.
Some script-layer changes of note:
- dns_AAAA_reply event signature changed: the string representation
of an IPv6 addr is easily derived from the addr value, it doesn't
need to be another parameter. This event also now generated directly
by the DNS analyzer instead of being "faked" into a dns_A_reply event.
- removed addr_to_count BIF. It used to return the host-order
count representation of IPv4 addresses only. To make it more
generic, we might later add a BIF to return a vector of counts
in order to support IPv6.
- changed the result of enclosing addr variables in vertical pipes
(e.g. |my_addr|) to return the bit-width of the address type which
is 128 for IPv6 and 32 for IPv4. It used to function the same
way as addr_to_count mentioned above.
- remove bro_has_ipv6 BIF
If 'use_conn_size_analyzer' is true, the event engine tracks number of
packets and raw IP bytes per connection. If report_conn_size_analyzer
is true, these values are included as four new columns into conn.log
I changed conn.bro so that the value of report_conn_size_analyzer
follows that of use_conn_size_analyzer. For the new conn.log, we
probably want to get rid of report_conn_size_analyzer anyway.
Removing everything related to trace rewriting.
(I wasn't too careful in ensuring that I catch everything in the
scripts; Seth is working on those anyway.)
(Merging by cherry-picking the corresponding commit, as the branch was
accidentally made off of the logging stuff).
