Matt Smith says: ==================== This patch series changes the type of bpf_object_skeleton->data to const void * and provides a helper method X__elf_bytes(size_t *sz) for accessing the raw binary data of the compiled embedded BPF object. The type change enforces the previously implied behavior of immutability for this field while casting it to (void *) before assignment allows for compiling with previous versions of the libbpf headers without compiler warnings. The helper method allows easier access to the BPF binary object data and is leveraged to populate the skeleton field. The inclusion of this helper method will allow users to get access to the data without needing to populate an entire skeleton first. Checks are added in the third patch to validate the behavior of the added method ==================== Signed-off-by: Andrii Nakryiko <andrii@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.
