- Accessible at script-layer through 'mobile_ipv6_message' event.
- All Mobile IPv6 analysis now enabled through --enable-mobile-ipv6
configure-time option, otherwise the mobility header, routing type 2,
and Home Address Destination option are ignored.
I copied the code over manually, no merging, because (1) it needed to
be adapted to the new threading API, and (2) there's more stuff in the
branch that I haven't ported yet.
The DS output generally seems to work, but it has seen no further
testing yet.
Not unit tests yet either.
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
- Missing GeoIP databases now generate warnings/errors that go through
the reporter framework instead of hitting GeoIP's internal use of
stderr
- lookup_location now just queries for country code if the city database
was not loaded, which gets rid of invalid database type errors.
- lookup_location now leaves missing fields uninitialized in the
returned geo_location record value. Updated existing scripts to
check for initialized fields in geo_location records before use.
- Fixed support for GeoIP's IPv6 API and databases
The CMake-generated config.h would redundantly define some types to
themselves, causing lots of warning in some cases (e.g. Xcode build).
This addresses #414
- Asynchronous DNS resolver support assumed by default
- HAVE_ASYNC_DNS, HAVE_NB_DNS, and USE_NB_DNS preprocessor definitions
removed
- In the process, I added FindBIND and CheckNameserCompat CMake modules
- Forgot to remove USE_SELECT_LOOP from BuildOptions.cmake
- ACTIVE_MAPPING removed from config.h.in, code cleanup still pending
- EXPIRE_DFA_STATES removed from config.h.in, code cleanup still pending
