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. [1]: https://lkml.org/lkml/2018/8/28/590 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 Documentation/ioctl/ioctl-number.txt | 1 + .../userspace-api/seccomp_filter.rst | 84 +++ arch/Kconfig | 9 + include/linux/seccomp.h | 18 +- include/uapi/linux/ptrace.h | 2 + include/uapi/linux/seccomp.h | 36 +- kernel/ptrace.c | 4 + kernel/seccomp.c | 538 +++++++++++++++- samples/seccomp/.gitignore | 1 + samples/seccomp/Makefile | 7 +- samples/seccomp/user-trap.c | 312 ++++++++++ tools/testing/selftests/seccomp/seccomp_bpf.c | 587 +++++++++++++++++- 12 files changed, 1586 insertions(+), 13 deletions(-) create mode 100644 samples/seccomp/user-trap.c -- 2.17.1
