Subject: [PATCH bpf-next v2 08/17] udp: Store layer 4 protocol in udp_table
Date: Mon, 11 May 2020 20:52:09 +0200	[thread overview]
Message-ID: <20200511185218.1422406-9-jakub@cloudflare.com> (raw)
In-Reply-To: <20200511185218.1422406-1-jakub@cloudflare.com>

Because UDP and UDP-Lite share code, we pass the L4 protocol identifier
alongside the UDP socket table to functions which need to distinguishing
between the two protocol.

Put the protocol identifier in the UDP table itself, so that the protocol
is known to any function in the call chain that operates on socket table.

Subsequent patches make use the new udp_table field at the socket lookup
time to ensure that BPF program selects only sockets with matching
protocol.
