    Subject[PATCH 4.9 049/102] hsr: set .netnsok flag
    Date
    From: Taehee Yoo <ap420073@gmail.com>

    [ Upstream commit 09e91dbea0aa32be02d8877bd50490813de56b9a ]

    The hsr module has been supporting the list and status command.
    (HSR_C_GET_NODE_LIST and HSR_C_GET_NODE_STATUS)
    These commands send node information to the user-space via generic netlink.
    But, in the non-init_net namespace, these commands are not allowed
    because .netnsok flag is false.
    So, there is no way to get node information in the non-init_net namespace.

    Fixes: f421436a591d ("net/hsr: Add support for the High-availability Seamless Redundancy protocol (HSRv0)")
