    Linus Torvalds authored
    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)"
