Merge tag 'for-linus-2020-04-18' of git://git.kernel.org/pub/scm/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"
* tag 'for-linus-2020-04-18' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux:
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

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
