Code Drop 2 Status Update
Code Drop 3 Status Update
Work since February has focused almost exclusively on the DNS library,
especially on database implementation and resolver architecture. The
DNS library now contains a transactional versioned database. In zone
mode, the database supports multiple concurrent readers as well as a
single in-progress abortable update (e.g. dynamic DNS or IXFR). In
cache mode, multiple concurrent readers and writers are supported. We
also have added interfaces for iterating the database, DNS
compression, parsing and writing DNS messages. Our tree code now has
support for bitstring labels (required for IPv6). DNS master file
loading is more robust than in the first code drop.
Work since the last code drop has focused on both the libraries and
the server. Some of the highlights are:
A significant amount of design and implementation work that we had
hoped to do later in the project had to be done in the current time
period. For example, both DNSSEC and IPv6 introduce DB and resolver
complexities that are so fundamental that they could not be deferred
until the time when we are actually implementing DNSSEC and IPv6
support. As a result, we have less code implemented than we had
hoped, but are ahead of plan on parts of the design.
Libraries
IPv6 sockets.
We are currently finalizing the resolver design, and will start
implementing it soon. Also nearing completion, but not included in
this release, are library data types representing zones, the cache,
and a standard C structure form for each rdata type.
DNSSEC security core, TSIG.
Shared libraries can now be generated.
Tests
Internationalization message catalog support. (Much of the
code has yet to be converted to use catalogs.)
A basic test framework and a set of tests are included in this
release. The tests are in
Server
Most of the temporary code in the server has been replaced
with the real thing. One exception is config file processing,
which has not yet been integrated.
bin/tests/master
bin/tests/names
bin/tests/rbt
Basic AXFR, IXFR, and dynamic update support.
The server now listens on IPv6 sockets, if the system
supports them.
To run a test, 'cd' into its directory and type 'make test'.
Result of the tests are appended to
The IPv6 reverse lookup scheme (bitstring labels and DNAME)
is supported by the server. A6 chain following remains
to be implemented.
bin/tests/t_journal
DNSSEC NXT records are returned in negative responses
for secure zones.
We expect the test suite to become richer over time.
Resolver
The skeleton of the resolver is in the kit. This
shows how the resolver is going to work, but the
resolver is not yet functional. This will be the
prime focus of work in the near future.

before you run ./configure. Many compiler warnings, etc. are currently
generated on IRIX. They will be cleaned up in a future release.
bin/named Note
Code in bin/named is for testing purposes only, and is not representative of
the final architecture. Currently, it can load multiple zones and also
a cache, and answer queries for those names. Because the server cannot
recurse, and because it does not yet implement the full DNS protocol,
it runs on port 5544, not port 53.
The configuration code in bin/named does not represent the final
architecture. The config file processing code in lib/dns/config will be
used by the server in the future. The server is still running on port
5544.
