[PATCH v17 00/15] seccomp_filter: BPF-based syscall filtering

[Will Drewry]

Please see prior revisions for a detailed discussion of this patch
series.

This series is a rebase on to:
  b5174fa3a7f4f8f150bfa3b917c92608953dfa0f
with very minor changes due to rebasing and tweaks noticed by a few
initial users.  (I will rebase again for v3.4-rc1 when that time comes.)

I realize now is a noisy time, but I wanted to get the most current
revision on the list.

As per prior posts, I am now including luto@'s PR_SET_NO_NEW_PRIVS
changes in the series for clarity and ease of testing.  This latest
rebased required required bumping the prctl() numbers for the
NO_NEW_PRIVS work due to the new reaper options.

For those inclined, the whole series can be found here too:
   https://github.com/redpig/linux/tree/seccomp

At this point, I'm not aware of any outstanding concerns, complaints,
etc. If there are any, I'd love to know.

Thanks!
