Right now, ironsides emits a STORAGE ERROR during building with
lang/gcc6-aux. It's unclear if the problem lies with compiler or with
ironsides. For now, limit building it with gcc5-aux (the default).
The USES=ada:5 setting wasn't supported, but it should have been. This
has also been fixed.
After contacting the author, he updated the snapshot to the latest,
remove 7M worth of dead files and adding a man page. I made some
corrections to that man page and converted it to mdoc tags.
GNATMake was used to clean up the WRKSRC after extraction, but the
problem is that it's not present at that point on a clean build; it
comes in later as a build dependency. Rather than a messy definition
of extract-depends, just remove the files manually without gnatmake.
IRONSIDES is an authoritative DNS server that is provably invulnerable to
many of the problems that plague other servers. It achieves this property
through the use of formal methods in its design, in particular the language
Ada and the SPARK formal methods tool set. Code validated in this way is
provably exception-free, contains no data flow errors, and terminates only
in the ways that its programmers explicitly say that it can. These are very
desirable properties from a computer security perspective.
IRONSIDES is not a complete implementation of DNS. In particular, it does
not support zone transfers or recursive queries. It does, however, support
a sufficient number of DNS records to be useful as an authoritative DNS
server for an enterprise.
