Teach libbpf how to parse code sections into potentially multiple bpf_program instances, based on ELF FUNC symbols. Each BPF program will keep track of its position within containing ELF section for translating section instruction offsets into program instruction offsets: regardless of BPF program's location in ELF section, it's first instruction is always at local instruction offset 0, so when libbpf is working with relocations (which use section-based instruction offsets) this is critical to make proper translations.

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.
