There were a couple of things that kept it from being suitable for our needs: The big one is that since the process tree is used to check policy, it's kept in-kernel and I'm primarily interested in having these events be easily exportable. IIRC (at least when I last looked), it wasn't possible to stream the events as they happened. tomoyo-queryd looks like it gets me real-time policy violations, but I don't have any policy per-se. I'm just trying to monitor processes and network activity. We also already use apparmor so switching to a different LSM was a non-trivial task (admittedly this is now an issue for hone too, but hone wasn't an LSM initially). > The combination is actually sufficient to implement what you want for Hone > _today_ as far as I can tell, and there's even the out-of-tree AKARI variant > if you want to use it together with another LSM. > > There's also Caitsith[3] (also from Tetsuo Handa), which might be even > better suited but is not in mainline yet. I'm not familiar with AKARI or Caitsith. I'll take a look.
