You should probably add a mailing list (L:) and source tree URL (T:)
to the IPE entry.  You can use the LSM mailing list to start if you
like, there are several LSMs that do that today, e.g. Smack, Landlock,
etc.  As far as the source tree is concerned, probably the easiest
option is a simple GitHub repo, but there are plenty of other choices
too.

Both the mailing list and the source URLs can always be updated in the
future so don't worry too much about being stuck with either long
term.
