[PATCH v6 0/5] seccomp trap to userspace

[Tycho Andersen]

Hi all,

Here's a v6 of the seccomp trap to userspace series. v5 [1] was fairly
quiet, with Christian reminding me that I had forgotten to update the
docs for the ioctl change. Other than that, there are no changes.

Thoughts welcome,

Tycho

Tycho Andersen (5):
  seccomp: add a return code to trap to userspace
  seccomp: make get_nth_filter available outside of CHECKPOINT_RESTORE
  seccomp: add a way to get a listener fd from ptrace
  seccomp: add support for passing fds via USER_NOTIF
  samples: add an example of seccomp user trap
