I would like to make a couple of improvements to security features in
stable:

1. Add the option to disable unprivileged use of perf_event_open().
   This rwequires a small out-of-tree patch that we've carried in
   unstable for some time.  In unstable this is also enabled by
   default, but I don't propose to do that in stable.

2. Enable seccomp (system call filtering) for ARM architectures
   (armel, armhf, arm64).  This is an architecture-dependent feature
   that is enabled on all other release architectures.  For arm64 this
   requires a backport; for the others it's just a config change.
   This expands the size of armel images by about 1K.

Are these suitable for a stable update?

Ben.

I say we take off; nuke the site from orbit.  It's the only way to be
sure.
