[PATCH net-next v3 20/32] net: Convert subsys_initcall() registered pernet_operations from net/sched

psched_net_ops only creates and destroyes /proc entry, and safe to be executed in parallel with any foreigh pernet_operations. tcf_action_net_ops initializes and destructs tcf_action_net::egdev_ht, which is not touched by foreign pernet_operations. So, make them async. Signed-off-by: Kirill

[PATCH net-next v3 14/32] net: Convert rtnetlink_net_ops

rtnetlink_net_init() and rtnetlink_net_exit() create and destroy netlink socket net::rtnl. The socket is used to send rtnl notification via rtnl_net_notifyid(). There is no a problem to create and destroy it in parallel with other pernet operations, as we link net in setup_net() after the socket

[PATCH net-next v3 16/32] net: Convert uevent_net_ops

uevent_net_init() and uevent_net_exit() create and destroy netlink socket, and these actions serialized in netlink code. Parallel execution with other pernet_operations makes the socket disappear earlier from uevent_sock_list on ->exit. As userspace can't be interested in broadcast messages of

[PATCH net-next v3 17/32] net: Convert proto_net_ops

This patch starts to convert pernet_subsys, registered from subsys initcalls. It seems safe to be executed in parallel with others, as it's only creates/destoyes proc entry, which nobody else is not interested in. Signed-off-by: Kirill Tkhai Acked-by: Andrei Vagin

[PATCH net-next v3 18/32] net: Convert pernet_subsys ops, registered via net_dev_init()

There are: 1)dev_proc_ops and dev_mc_net_ops, which create and destroy pernet proc file and not interesting for another net namespaces; 2)netdev_net_ops, which creates pernet hashes, which are not touched by another pernet_operations. So, make them async. Signed-off-by: Kirill Tkhai

[PATCH net-next v3 15/32] net: Convert audit_net_ops

This patch starts to convert pernet_subsys, registered from postcore initcalls. audit_net_init() creates netlink socket, while audit_net_exit() destroys it. The rest of the pernet_list are not interested in the socket, so we make audit_net_ops async. Signed-off-by: Kirill Tkhai

This is the 7th version patchset to add the Linux kernel port for Andes(nds32) processors. Almost all of the feedbacks from v6 patchseries has been addressed and we rebase it to v4.16-rc1. Thanks to everyone who provided feedback and help on the previous version. This patchset adds core

[PATCH net-next v3 30/32] net: Convert default_device_ops

These pernet operations consist of exit() and exit_batch() methods. default_device_exit() moves not-local and virtual devices to init_net. There is nothing exciting, because this may happen in any time on a working system, and rtnl_lock() and synchronize_net() protect us from all cases of

[PATCH net-next v3 31/32] net: Convert diag_net_ops

[PATCH net-next v3 29/32] net: Convert loopback_net_ops

These pernet_operations have only init() method. It allocates memory for net_device, calls register_netdev() and assigns net::loopback_dev. register_netdev() is allowed be used without additional locks, as it's synchronized on rtnl_lock(). There are many examples of using this functon directly

[patch net-next 2/2] mlxsw: spectrum: Distinguish between IPv4/6 tunnels

From: Petr Machata struct ip_tunnel_parm, where GRE and several other tunnel types hold information, is IPv4-specific. The current router / ipip code in mlxsw however uses it as if it were generic. Make it clear that it's not. Rename many functions from _params_ to
