Add "disable" module parameter support to ipv6.ko by specifying
"disable=1" on module load. We just do the minimum of initializing
inetsw6[] so calls from other modules to inet6_register_protosw()
won't OOPs, then bail out. No IPv6 addresses or sockets can be
created as a result, and a reboot is required to enable IPv6.Signed-off-by: Brian Haley

When a network namespace is destroyed the network interfaces are
all unregistered, making addrconf_ifdown called by the netdevice
notifier.
In the other hand, the addrconf exit method does a loop on the network
devices and does addrconf_ifdown on each of them. But the ordering of
the netns subsystem is not right because it uses the register_pernet_device
instead of register_pernet_subsys. If we handle the loopback as
any network device, we can safely use register_pernet_subsys.But if we use register_pernet_subsys, the addrconf exit method will do
exactly what was already done with the unregistering of the network
devices. So in definitive, this code is pointless.I removed the netns addrconf exit method and moved the code to the
addrconf cleanup function.Signed-off-by: Daniel Lezcano

We already have a valid net in that place, but this is not just a
cleanup - the tw pointer can be NULL there sometimes, thus causing
an oops in NET_NS=y case.The same place in ipv4 code already works correctly using existing
net, rather than tw's one.The bug exists since 2.6.27.

This patch addresses the IPv6 multicast routing issues described
below. It was tested with XORP 1.4/1.5 as the IPv6 PIM-SM routing
daemon against FreeBSD peers.net/ipv6/ip6_input.c:
- Don't try to forward link-local multicast packets.
- Don't reset skb2->dev before calling ip6_mr_input() so packets can
be identified as coming from the PIM register vif properly.net/ipv6/ip6mr.c:
- Fix incoming PIM register messages processing:
* The IPv6 pseudo-header should be included when checksumming PIM
messages (RFC 4601 section 4.9; RFC 3973 section 4.7.1).* Packets decapsulated from PIM register messages should have
skb->protocol ETH_P_IPV6.- Enable/disable IPv6 multicast forwarding on the corresponding
interface when a routing daemon adds/removes a multicast virtual
interface.- Remove incorrect skb_pull() to fix userspace signaling.
- Enable/disable global IPv6 multicast forwarding when an IPv6
multicast routing socket is opened/closed.net/ipv6/route.c:
- Don't use strict routing logic for packets decapsulated from PIM
register messages (similar to disabling rp_filter for the IPv4
case).Signed-off-by: Thomas Goff

Thanks to excellent diagnosis by Eduard Guzovsky.
The core problem is that on a network with lots of active
multicast traffic, the neighbour cache can fill up. If
we try to allocate a new route and thus neighbour cache
entry, the bog-standard GC attempt the neighbour layer does
in ineffective because route entries hold a reference
to the existing neighbour entries and GC can only liberate
entries with no references.IPV4 already has a way to handle this, by doing a route cache
GC in such situations (when neigh attach returns -ENOBUFS).So simply mimick this on the ipv6 side.

This last patch makes the appropriate changes to use and propagate the
network namespace where needed in IPv6 multicast forwarding code.This consists mainly in replacing all the remaining init_net occurences
with current netns pointer retrieved from sockets, net devices or
mfc6_caches depending on the routines' contexts.Some routines receive a new 'struct net' parameter to propagate the current
netns:
* ip6mr_get_route
* ip6mr_cache_report
* ip6mr_cache_find
* ip6mr_cache_unresolved
* mif6_add/mif6_delete
* ip6mr_mfc_add/ip6mr_mfc_delete
* ip6mr_reg_vifAll the IPv6 multicast forwarding variables moved to struct netns_ipv6 by
the previous patches are now referenced in the correct namespace.Changelog:
==========
* Take into account the net associated to mfc6_cache when matching entries in
mfc_unres_queue list.
* Call mroute_clean_tables() in ip6mr_net_exit() to free memory allocated
per-namespace.
* Call dev_net_set() in ip6mr_reg_vif() to initialize dev->nd_net
correctly.Signed-off-by: Benjamin Thery

Preliminary work to make IPv6 multicast forwarding netns-aware.
Declare variable cache_resolve_queue_len per-namespace: moves it into
struct netns_ipv6.This variable counts the number of unresolved cache entries queued in the
list mfc_unres_queue. This list is kept global to all netns as the number
of entries per namespace is limited to 10 (hardcoded in routine
ip6mr_cache_unresolved).
Entries belonging to different namespaces in mfc_unres_queue will be
identified by matching the mfc_net member introduced previously in
struct mfc6_cache.Keeping this list global to all netns, also allows us to keep a single
timer (ipmr_expire_timer) to handle their expiration.
In some places cache_resolve_queue_len value was tested for arming
or deleting the timer. These tests were equivalent to testing
mfc_unres_queue value instead and are replaced in this patch.At the moment, cache_resolve_queue_len is only referenced in init_net.
