In preparation to move test cases from bpf/test_sock_addr.c that expect ATTACH_REJECT, this patch adds BPF_SKEL_FUNCS_RAW to generate load and destroy functions that use bpf_prog_attach() to control the attach_type. The normal load functions use bpf_program__attach_cgroup which does not have the same degree of control over the attach type, as bpf_program_attach_fd() calls bpf_link_create() with the attach type extracted from prog using bpf_program__expected_attach_type(). It is currently not possible to modify the attach type before bpf_program__attach_cgroup() is called, since bpf_program__set_expected_attach_type() has no effect after the program is loaded.

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 reStructuredText 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.
