Subject: [PATCH v1 bpf-next 02/11] bpf: Define migration types for SO_REUSEPORT.
Date: Tue, 1 Dec 2020 23:44:09 +0900 [thread overview]
Message-ID: <20201201144418.35045-3-kuniyu@amazon.co.jp> (raw)
In-Reply-To: <20201201144418.35045-1-kuniyu@amazon.co.jp>
As noted in the preceding commit, there are two migration types. In
addition to that, the kernel will run the same eBPF program to select a
listener for SYN packets.
This patch defines three types to signal the kernel and the eBPF program if
it is receiving a new request or migrating ESTABLISHED/SYN_RECV sockets in
the accept queue or NEW_SYN_RECV socket during 3WHS.
