Hi, the following merge-commit, which has been accepted into bpf-next for inclusion in v4.21, addresses the problem raised above by clarifying that the licence of bpftool is GPLv2-only + BSD-2-Clause. commit 00842be52f2015c3c1028e16b565f325f4ca20fc Merge: 8f9a8a619311 907b22365115 Author: Daniel Borkmann <[email protected]> Date: Thu Dec 13 12:08:45 2018 +0100 Merge branch 'bpf-bpftool-license-update' Jakub Kicinski says: ==================== We are changing/clarifying the license on bpftool to GPLv2-only + BSD-2-Clause for all files. Current license mix is incompatible with libbfd (which is GPLv3-only) and therefore Debian maintainers are apprehensive about packaging bpftool. Acks include authors of code which has been copied into bpftool (e.g. JSON writer from iproute2, code from tools/bpf, code from BPF samples and selftests, etc.) Thanks again to all the authors who acked the change! ==================== Acked-by: Roman Gushchin <[email protected]> Acked-by: YueHaibing <[email protected]> Acked-by: Yonghong Song <[email protected]> Acked-by: Stanislav Fomichev <[email protected]> Acked-by: Sean Young <[email protected]> Acked-by: Jiri Benc <[email protected]> Acked-by: David Calavera <[email protected]> Acked-by: Andrey Ignatov <[email protected]> Acked-by: Joe Stringer <[email protected]> Acked-by: David Ahern <[email protected]> Acked-by: Alexei Starovoitov <[email protected]> Acked-by: Petar Penkov <[email protected]> Acked-by: Sandipan Das <[email protected]> Acked-by: Prashant Bhole <[email protected]> Acked-by: Stephen Hemminger <[email protected]> Acked-by: John Fastabend <[email protected]> Acked-by: Taeung Song <[email protected]> Acked-by: Jiri Olsa <[email protected]> Acked-by: Daniel Borkmann <[email protected]> CC: [email protected] Signed-off-by: Daniel Borkmann <[email protected]>
