Without CONFIG_NET_NS, namespace is always &init_net.
Compiler will be able to omit namespace comparisons with this patch.

can: add sanity checks2008-07-06T06:38:43ZOliver Hartkopp2008-07-06T06:38:43Zurn:sha1:7f2d38eb7a42bea1c1df51bbdaa2ca0f0bdda07f
Even though the CAN netlayer only deals with CAN netdevices, the
netlayer interface to the userspace and to the device layer should
perform some sanity checks.
This patch adds several sanity checks that mainly prevent userspace apps
to send broken content into the system that may be misinterpreted by
some other userspace application.

can: Fix copy_from_user() results interpretation2008-04-27T21:26:51ZSam Ravnborg2008-04-27T05:57:25Zurn:sha1:3f91bd420a955803421f2db17b2e04aacfbb2bb8
Both copy_to_ and _from_user return the number of bytes, that failed to
reach their destination, not the 0/-EXXX values.

net: Fix wrong interpretation of some copy_to_user() results.2008-04-25T08:49:48ZPavel Emelyanov2008-04-25T08:49:48Zurn:sha1:653252c2302cdf2dfbca66a7e177f7db783f9efa
I found some places, that erroneously return the value obtained from
the copy_to_user() call: if some amount of bytes were not able to get
to the user (this is what this one returns) the proper behavior is to
return the -EFAULT error, not that number itself.

[NET] NETNS: Omit net_device->nd_net without CONFIG_NET_NS.2008-03-25T19:39:53ZYOSHIFUJI Hideaki2008-03-25T12:47:49Zurn:sha1:c346dca10840a874240c78efe3f39acf4312a1f2
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.

Remove unneeded variable.
Rename local variable error to err like in all other places.
Some white-space changes.
