This is needed to support sock{map|hash} use from bpftool. Currently, I carry around custom code to do this so doing it using standard bpftool will be great. The second patch adds a compat mode to ignore non-zero entries in the map def. This allows using bpftool with maps that have a extra fields that the user knows can be ignored. This is needed to work correctly with maps being loaded by other tools or directly via syscalls. v3: add bash completion and doc updates for --mapcompat --- John Fastabend (2): bpf: bpftool, add support for attaching programs to maps bpf: bpftool, add flag to allow non-compat map definitions tools/bpf/bpftool/Documentation/bpftool-prog.rst | 11 ++ tools/bpf/bpftool/Documentation/bpftool.rst | 6 + tools/bpf/bpftool/bash-completion/bpftool | 21 ++++- tools/bpf/bpftool/main.c | 7 +- tools/bpf/bpftool/main.h | 3 - tools/bpf/bpftool/prog.c | 101 ++++++++++++++++++++++ 6 files changed, 142 insertions(+), 7 deletions(-)
