[NETNS][IPV6]: Add ipv6 structure for netns. Like the ipv4 part, this patch adds an ipv6 structure in the net structure to aggregate the different resources to make ipv6 per namespace. Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

/*
* ipv6 in net namespaces
*/
[NETNS][IPV6]: Make ip6_frags per namespace. The ip6_frags is moved to the network namespace structure. Because there can be multiple instances of the network namespaces, and the ip6_frags is no longer a global static variable, a helper function has been added to facilitate the initialization of the variables. Until the ipv6 protocol is not per namespace, the variables are accessed relatively from the initial network namespace. Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: David S.

[NETNS]: Create ipv6 devconf-s for namespaces This is the core. Declare and register the pernet subsys for addrconf. The init callback the will create the devconf-s. The init_net will reuse the existing statically declared confs, so that accessing them from inside the ipv6 code will still work. The register_pernet_subsys() is moved above the ipv6_add_dev() call for loopback, because this function will need the net->devconf_dflt pointer to be already set.

[NETNS][FRAGS]: Make the inet_frag_queue lookup work in namespaces. Since fragment management code is consolidated, we cannot have the pointer from inet_frag_queue to struct net, since we must know what king of fragment this is. So, I introduce the netns_frags structure. This one is currently empty, but will be eventually filled with per-namespace attributes. Each inet_frag_queue is tagged with this one. The conntrack_reasm is not "netns-izated", so it has one static netns_frags instance to keep working in init namespace. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.
