Subject: [PATCH bpf-next 6/8] libbpf: Recognize SK_REUSEPORT programs from section name
Date: Sat, 23 Nov 2019 12:07:49 +0100 [thread overview]
Message-ID: <20191123110751.6729-7-jakub@cloudflare.com> (raw)
In-Reply-To: <20191123110751.6729-1-jakub@cloudflare.com>
Allow loading BPF object files that contain SK_REUSEPORT programs without
having to manually set the program type before load if the the section name
is set to "sk_reuseport".
Makes user-space code needed to load SK_REUSEPORT BPF program more concise.
