Hi Will,
just one note - in my original comment I wasn't actually suggesting
disabling setting of filters through a writeable file - I was only
suggesting restricting writing to one's own filters file.
All the better if it is possible to get a nice prctl-only
interface, but if it ends up limiting rule expressiveness (or taking
years to define an interface) then perhaps we should stick with
prctl for setting seccomp mode, and a more expressive file interface
for defining filters.
