2009-11-08net: Support specifying the network namespace upon device creation.Eric W. Biederman
There is no good reason to not support userspace specifying the network namespace during device creation, and it makes it easier to create a network device and pass it to a child network namespace with a well known name. We have to be careful to ensure that the target network namespace for the new device exists through the life of the call. To keep that logic clear I have factored out the network namespace grabbing logic into rtnl_link_get_net. In addtion we need to continue to pass the source network namespace to the rtnl_link_ops.newlink method so that we can find the base device source network namespace. Signed-off-by: Eric W.

2009-11-08can: fix WARN_ON dump in net/core/rtnetlink.c:rtmsg_ifinfo()Wolfgang Grandegger
On older kernels, e.g. 2.6.27, a WARN_ON dump in rtmsg_ifinfo() is thrown when the CAN device is registered due to insufficient skb space, as reported by various users. This patch adds the rtnl_link_ops "get_size" to fix the problem. I think this patch is required for more recent kernels as well, even if no WARN_ON dumps are triggered. Maybe we also need "get_xstats_size" for the CAN xstats. Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: David S. Miller <davem@davemloft.net>

So, instead of introducing the casts, rework the code to substitute an offset from an already mapped area. This makes the code a lot simpler and less duplicated. Plus, from now on we don't actually map reserved registers on non-etsec2.0 devices, so we have more chances to catch programming errors.

2009-11-06net, compat_ioctl: handle socket ioctl abuses in tty driversArnd Bergmann
Slip and a few other drivers use the same ioctl numbers on tty devices that are normally meant for sockets. This causes problems with our compat_ioctl handling that tries to convert the data structures in a different format. Fortunately, these five drivers all use 32 bit compatible data structures in the ioctl numbers, so we can just add a trivial compat_ioctl conversion function to each of them. SIOCSIFENCAP and SIOCGIFENCAP do not need to live in fs/compat_ioctl.c after this any more, and they are not used on any sockets. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-11-06net/tun: handle compat_ioctl directlyArnd Bergmann
The tun driver is the only code in the kernel that operates on a character device with struct ifreq. Change the driver to handle the conversion itself so we can contain the remaining ifreq handling in the socket layer. This also fixes a bug in the handling of invalid ioctl numbers on an unbound tun device. The driver treats this as a TUNSETIFF in native mode, but there is no way for the generic compat_ioctl() function to emulate this behaviour. Possibly the driver was only doing this accidentally anyway, but if any code relies on this misfeature, it now also works in compat mode.
