Subject: [PATCH bpf-next 0/8] Add bpf programmable device
Date: Tue, 26 Sep 2023 07:59:05 +0200 [thread overview]
Message-ID: <20230926055913.9859-1-daniel@iogearbox.net> (raw)
This work adds a BPF programmable device which can operate in L3 or L2
mode where the BPF program is part of the xmit routine. It's program
management is done via bpf_mprog and it comes with BPF link support.
For details see patch 1 and following. Thanks!
Daniel Borkmann (8):
meta, bpf: Add bpf programmable meta device
meta, bpf: Add bpf link support for meta device
tools: Sync if_link uapi header
libbpf: Add link-based API for meta
bpftool: Implement link show support for meta
bpftool: Extend net dump with meta progs
selftests/bpf: Add netlink helper library
selftests/bpf: Add selftests for meta
