net: The world is not perfect patch.

2008-05-22T00:47:54+00:00

  Unless there will be any objection here, I suggest consider the
following patch which simply removes the code for the
-DI_WISH_WORLD_WERE_PERFECT in the three methods which use it.

The compilation errors we get when using -DI_WISH_WORLD_WERE_PERFECT
show that this code was not built and not used for really a long time.

[GRE]: Allow for IPPROTO_GRE protocol in namespaces.

2008-04-16T08:11:36+00:00

This one was also disabled by default for sanity.

[GRE]: Allow to create IPGRE tunnels in net namespaces.

2008-04-16T08:11:13+00:00

I.e. set the proper net and mark as NETNS_LOCAL.

[GRE]: Use proper net in routing calls.

2008-04-16T08:10:44+00:00

As for the IPIP tunnel, there are some ip_route_output_key()
calls in there that require a proper net so give one to them.

And a proper net for the __get_dev_by_index hanging around.

[GRE]: Make tunnels hashes per-net.

2008-04-16T08:10:26+00:00

Very similar to what was done for the IPIP code.

[GRE]: Make the fallback tunnel device per-net.

2008-04-16T08:10:05+00:00

Everything is prepared for this change now. Create on in
init callback, use it over the code and destroy on net exit.

[GRE]: Use proper net in hash-lookup functions.

2008-04-16T08:09:44+00:00

This is the part#2 of the patch #2 - get the proper net for
these functions. This change in a separate patch in order not
to get lost in a large previous patch.

[GRE]: Add net/gre_net argument to some functions.

2008-04-16T08:09:22+00:00

The fallback device and hashes are to become per-net, but many
code doesn't have anything to get the struct net pointer from.

So pass the proper net there with an extra argument.

[NET] NETNS: Omit net_device->nd_net without CONFIG_NET_NS.

2008-03-25T19:39:53+00:00

Introduce per-net_device inlines: dev_net(), dev_net_set().
Without CONFIG_NET_NS, no namespace other than &init_net exists.
Let's explicitly define them to help compiler optimizations.
