Hi all, Here's a v9 of the seccomp trap to userspace series. Major changes are: * drop the whole SIGNALED flag thing. This was confusing to a number of people, and Oleg pointed out that it makes it fairly easy to get a task into an uninterruptible sleep. Now, replies to a task with a signal will just get ENOENT, indicating that something happened to the other end. * refactor the tests so that each test tests only one thing :) * several other minor bug fixes Cheers, Tycho Link to v8: https://lore.kernel.org/lkml/20181029224031.29809-1-tycho@xxxxxxxx/T/#u Tycho Andersen (4): seccomp: hoist struct seccomp_data recalculation higher seccomp: switch system call argument type to void * seccomp: add a return code to trap to userspace samples: add an example of seccomp user trap Documentation/ioctl/ioctl-number.txt | 1 + .../userspace-api/seccomp_filter.rst | 84 ++++ include/linux/seccomp.h | 9 +- include/uapi/linux/seccomp.h | 40 +- kernel/seccomp.c | 468 +++++++++++++++++- samples/seccomp/.gitignore | 1 + samples/seccomp/Makefile | 7 +- samples/seccomp/user-trap.c | 375 ++++++++++++++ tools/testing/selftests/seccomp/seccomp_bpf.c | 447 ++++++++++++++++- 9 files changed, 1410 insertions(+), 22 deletions(-) create mode 100644 samples/seccomp/user-trap.c -- 2.19.1
