Merge tag 'for-linus-2020-04-18' of git://git./linux/kernel/git/brauner/linux

Pull thread fixes from Christian Brauner:
 "A few fixes and minor improvements:

   - Correctly validate the cgroup file descriptor when clone3() is used
     with CLONE_INTO_CGROUP.

   - Check that a new enough version of struct clone_args is passed
     which supports the cgroup file descriptor argument when
     CLONE_INTO_CGROUP is set in the flags argument.

   - Catch nonsensical struct clone_args layouts at build time.

   - Catch extensions of struct clone_args without updating the uapi
     visible size definitions at build time.

   - Check whether the signal is valid early in kill_pid_usb_asyncio()
     before doing further work.

   - Replace open-coded rcu_read_lock()+kill_pid_info()+rcu_read_unlock()
     sequence in kill_something_info() with kill_proc_info() which is a
     dedicated helper to do just that"

  clone3: add build-time CLONE_ARGS_SIZE_VER* validity checks
  clone3: add a check for the user struct size if CLONE_INTO_CGROUP is set
  clone3: fix cgroup argument sanity check
  signal: use kill_proc_info instead of kill_pid_info in kill_something_info
  signal: check sig before setting info in kill_pid_usb_asyncio
