Merge tag 'seccomp-v5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull seccomp updates from Kees Cook:
 "There are a bunch of clean ups and selftest improvements along with
  two major updates to the SECCOMP_RET_USER_NOTIF filter return:
  EPOLLHUP support to more easily detect the death of a monitored
  process, and being able to inject fds when intercepting syscalls that
  expect an fd-opening side-effect (needed by both container folks and
  Chrome). The latter continued the refactoring of __scm_install_fd()
  started by Christoph, and in the process found and fixed a handful of
  bugs in various callers.

   - Improved selftest coverage, timeouts, and reporting

   - Add EPOLLHUP support for SECCOMP_RET_USER_NOTIF (Christian Brauner)

   - Refactor __scm_install_fd() into __receive_fd() and fix buggy
     callers

   - Introduce 'addfd' command for SECCOMP_RET_USER_NOTIF (Sargun
     Dhillon)"
