Subject[PATCH v9 0/4] seccomp trap to userspace
Date
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@tycho.ws/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
