mainlining shenanigans

Lorenz Bauer says: ==================== Right now, there is no safe way to use BPF_PROG_TEST_RUN with data_out. This is because bpf_test_finish copies the output buffer to user space without checking its size. This can lead to the kernel overwriting data in user space after the buffer if xdp_adjust_head and friends are in play. Thanks to everyone for their advice and patience with this patch set! Changes in v5: * Fix up libbpf.map Changes in v4: * Document bpf_prog_test_run and bpf_prog_test_run_xattr * Use struct bpf_prog_test_run_attr for return values Changes in v3: * Introduce bpf_prog_test_run_xattr instead of modifying the existing function Changes in v2: * Make the syscall return ENOSPC if data_size_out is too small * Make bpf_prog_test_run return EINVAL if size_out is missing * Document the new behaviour of data_size_out ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

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.
