* net: Support specifying the network namespace upon device creation.Eric W. Biederman2009-11-087-23/+50
| | | | | | | | | | | | | | | | | | | 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.

* compat: move sockios handling to net/socket.cArnd Bergmann2009-11-072-950/+240
| | | | | | | | | | | | | | | | | | | | | | | | | This removes the original socket compat_ioctl code from fs/compat_ioctl.c and converts the code from the copy in net/socket.c into a single function. We add a few cycles of runtime to compat_sock_ioctl() with the long switch() statement, but gain some cycles in return by simplifying the call chain to get there.

* net, compat_ioctl: handle socket ioctl abuses in tty driversArnd Bergmann2009-11-076-2/+103
| | | | | | | | | | | | | | | | | | 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.

* net/tun: handle compat_ioctl directlyArnd Bergmann2009-11-072-27/+46
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The USB code was incorrectly specifiying timeouts to be in jiffies vs msecs. On top of that, lower it to 200ms, as 1s is really too long (doesn't allow the watchdog to trip a reset if the device timesout too often). Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i2400m, when conected, will negotiate with the WiMAX basestation to put the link in IDLE mode when it is not being used. Upon RX/TX traffic, the link has to be restablished and that might require some crypto handshakes and maybe a DHCP renew. This process might take up to 20 (!) seconds and in some cases we were seeing network watchdog warnings that weren't needed. So the network watchdog timeout is updated to be slightly above that 20s threshold. As well, the driver itself will double check if the device is stuck in IDLE mode -- if that happens, the device will be reset (in this case the queue is also woken up to remove bogus--once the device is reset--warnings).

| * | wimax/i2400m: introduce i2400m_reset(), stopping TX and carrierInaky Perez-Gonzalez2009-11-039-21/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the i2400m driver was resetting by just calling i2400m->bus_reset(). However, this was missing stopping the TX queue and downing the carrier. This was causing, for the corner case of the driver reseting a device that refuses to go out of idle mode, that a few packets would be queued and more than one reset would go through, making the recovery a wee bit messy. To avoid introducing the same cleanup in all the bus-specific driver, introduced a i2400m_reset() function that takes care of house cleaning and then calling the bus-level reset implementation. The bulk of the changes in all files are just to rename the call from i2400m->bus_reset() to i2400m_reset(). Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com>
