Jesper Dangaard Brouer says: ==================== While playing with using libbpf for the Suricata project, we had issues LLVM >= 4.0.1 generating ELF files that could not be loaded with libbpf (tools/lib/bpf/). During the troubleshooting phase, I wrote a test program and improved the debugging output in libbpf. I turned this into a selftests program, and it also serves as a code example for libbpf in itself. I discovered that there are at least three ELF load issues with libbpf. I left them as TODO comments in (tools/testing/selftests/bpf) test_libbpf.sh. I've only fixed the load issue with eh_frames, and other types of relo-section that does not have exec flags. We can work on the other issues later. ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
