[PATCH net-next 13/15] mptcp: get addr in userspace pm list

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Geliang Tang <tanggeliang@xxxxxxxxxx>

This patch renames mptcp_pm_nl_get_addr_doit() as a dedicated in-kernel
netlink PM get addr function mptcp_pm_nl_get_addr(). and invoke a new
wrapper mptcp_pm_get_addr() in mptcp_pm_nl_get_addr_doit.

If a token is gotten in the wrapper, that means a userspace PM is used.
So invoke mptcp_userspace_pm_get_addr() to get addr in userspace PM list.
Otherwise, invoke mptcp_pm_nl_get_addr().
