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.

[IPIP]: Allow to create IPIP tunnels in net namespaces.

2008-04-16T08:06:18+00:00

Set the proper net before calling register_netdev and disable 
the tunnel device netns changing.

[IPIP]: Use proper net in (mostly) routing calls.

2008-04-16T08:05:57+00:00

There are some ip_route_output_key() calls in there that require
a proper net so give one to them.

Besides - give a proper net to a single __get_dev_by_index call 
in ipip_tunnel_bind_dev().

[IPIP]: Make tunnels hashes per net.

2008-04-16T08:05:32+00:00

Either net or ipip_net already exists in all the required 
places, so just use one.

Besides, tune net_init and net_exit calls to respectively 
initialize the hashes and destroy devices.

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

2008-04-16T08:05:03+00:00

This is the part#2 of the previous patch - get the proper
net for these functions.

I make it in a separate patch, so that this change does not
get lost in a large previous patch.

[IPIP]: Add net/ipip_net argument to some functions.

2008-04-16T08:04:35+00:00

The hashes of tunnels will be per-net too, so prepare all the 
functions that uses them for this change by adding an argument.

Use init_net temporarily in places, where the net does not exist
explicitly yet.

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

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

Create on in ipip_init_net(), use it all over the code (the
proper place to get the net from already exists) and destroy
in ipip_net_exit().

[IPV4]: Add 'rtable' field in struct sk_buff to alias 'dst' and avoid casts

2008-03-06T02:30:47+00:00

(Anonymous) unions can help us to avoid ugly casts.

A common cast it the (struct rtable *)skb->dst one.

Defining an union like  :
union {
     struct dst_entry *dst;
     struct rtable *rtable;
};
permits to use skb->rtable in place.

[INET]: Don't create tunnels with '%' in name.

2008-02-27T07:51:04+00:00

Four tunnel drivers (ip_gre, ipip, ip6_tunnel and sit) can receive a
pre-defined name for a device from the userspace.  Since these drivers
call the register_netdevice() (rtnl_lock, is held), which does _not_
generate the device's name, this name may contain a '%' character.

Not sure how bad is this to have a device with a '%' in its name, but
all the other places either use the register_netdev(), which call the
dev_alloc_name(), or explicitly call the dev_alloc_name() before
registering, i.e. do not allow for such names.

This had to be prior to the commit 34cc7b, but I forgot to number the
patches and this one got lost, sorry.
