From 1d0507f46843b14b0cb051fe50ebc7e6432111ab Mon Sep 17 00:00:00 2001 From: Davide Caratti Date: Mon, 23 Oct 2023 11:17:07 -0700 Subject: net: mptcp: convert netlink from small_ops to ops in the current MPTCP control plane, all operations use a netlink attribute of the same type "MPTCP_PM_ATTR". However, add/del/get/flush operations only parse the first element in the message _ the one that describes MPTCP endpoints (that was named MPTCP_PM_ATTR_ADDR and mostly used in ADD_ADDR operations _ probably the similarity of "attr", "addr" and "add" might cause some confusion to human readers). Convert MPTCP from 'small_ops' to 'ops', thus allowing different attributes for each single operation, hopefully makes all this clearer to human readers. - use a separate attribute set for add/del/get/flush address operation, binary compatible with the existing one, to store the endpoint address. MPTCP_PM_ENDPOINT_ADDR is added to the uAPI (with the same value as MPTCP_PM_ATTR_ADDR) for these operations. - convert mptcp_pm_ops[] and add policy files accordingly. this prepares MPTCP control plane to be described as YAML spec.
