Libbpf picks the name of the first symbol in the corresponding elf section to use as a program name. But without taking symbol's scope into account it may end's up with some local label as a program name. E.g.: $ bpftool prog 1: type 15 name LBB0_10 tag 0390a5136ba23f5c loaded_at Dec 07/17:22 uid 0 xlated 456B not jited memlock 4096B Fix this by preferring global symbols as program name. For instance: $ bpftool prog 1: type 15 name bpf_prog1 tag 0390a5136ba23f5c loaded_at Dec 07/17:26 uid 0 xlated 456B not jited memlock 4096B Signed-off-by: Roman Gushchin <guro@fb.com> Cc: Alexei Starovoitov <ast@kernel.org> Cc: Daniel Borkmann <daniel@iogearbox.net> Cc: Jakub Kicinski <jakub.kicinski@netronome.com> Cc: Martin KaFai Lau <kafai@fb.com> Cc: Quentin Monnet <quentin.monnet@netronome.com> Cc: David Ahern <dsahern@gmail.com> 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.
