Daniel Lezcano 63152fc0de [NETNS][IPV6] ip6_fib - gc timer per namespace
Move the timer initialization at the network namespace creation and
store the network namespace in the timer argument.

That enables multiple timers (one per network namespace) to do garbage
collecting.

Daniel Lezcano 58f09b78b7 [NETNS][IPV6] ip6_fib - make it per network namespace
The fib table for ipv6 are moved to the network namespace structure.
All references to them are made relatively to the network namespace.

All external calls to the ip6_fib functions taking the network
namespace parameter are made using the init_net variable, so the
ip6_fib engine is ready for the namespaces but the callers not yet.

Denis V. Lunev 98c6d1b261 [NETNS]: Make icmpv6_sk per namespace.
All preparations are done. Now just add a hook to perform an
initialization on namespace startup and replace icmpv6_sk macro with
proper inline call.  Actual namespace the packet belongs too will be
passed later along with the one for the routing.

Alexey Dobriyan 8280aa6182 [NETFILTER]: ip6_tables: per-netns IPv6 FILTER, MANGLE, RAW
Now it's possible to list and manipulate per-netns ip6tables rules.
Filtering decisions are based on init_net's table so far.

P.S.: remove init_net check in inet6_create() to see the effect

Pavel Emelyanov 3b4bc4a2bf [NETNS][FRAGS]: Isolate the secret interval from namespaces.
Since we have one hashtable to lookup the fragment, having
different secret_interval-s for hash rebuild doesn't make
sense, so move this one to inet_frags.

The inet_frags_ctl becomes empty after this, so remove it.
The appropriate ctl table is kept read-only in namespaces.

Pavel Emelyanov e4a2d5c2bc [NETNS][FRAGS]: Duplicate sysctl tables for new namespaces.
Each namespace has to have own tables to tune their
different parameters, so duplicate the tables and
register them.

All the tables in sub-namespaces are temporarily made
read-only.

Pavel Emelyanov ac18e7509e [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.

Pavel Emelyanov e0da5a480c [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.

Daniel Lezcano 41a76906b3 [NETNS][IPV6]: Make icmpv6_time sysctl per namespace.
This patch moves the icmpv6_time sysctl to the network namespace
structure.

Because the ipv6 protocol is not yet per namespace, the variable is
accessed relatively to the initial network namespace.

Daniel Lezcano 4990509f19 [NETNS][IPV6]: Make sysctls route per namespace.
All the sysctl concerning the routes are moved to the network
namespace structure. A helper function is called to initialize the
variables.

Because the ipv6 protocol is not yet per namespace, the variables are
accessed relatively from the network namespace.

Daniel Lezcano e71e0349eb [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.

Daniel Lezcano 760f2d0186 [NETNS][IPV6]: Make multiple instance of sysctl tables.
Each network namespace wants its own set of sysctl value, eg. we
should not be able from a namespace to set a sysctl value for another
namespace , especially for the initial network namespace.

This patch duplicates the sysctl table when we register a new network
namespace for ipv6. The duplicated table are postfixed with the
"template" word to notify the developper the table is cloned.
