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
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).
(now actually commiting all the files)
This change is actually two-fold:
a) bif's now accept module XYZ; statements and module::ID for
function, const, event, enum, etc. declartation
b) Added C++-namespaces to variables, functions, etc. that are declared
in bif but accessed from C++
This required some (lightweight) re-factoring of the C++ codes.
Note, event's don't have their own C++ namespace yet, since this
would require a rather huge re-factoring.
Compiles and passes test suite.
New namespace feature not tested yet.
Documentation to follow.
