2009-09-23drivers/net/wireless: Use usb_endpoint_dir_outJulia Lawall
Use the usb_endpoint_dir_out API function. Note that the use of USB_TYPE_MASK in the original code is incorrect; it results in a test that is always false. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ struct usb_endpoint_descriptor *endpoint; expression E; @@ - (endpoint->bEndpointAddress & E) == USB_DIR_OUT + usb_endpoint_dir_out(endpoint) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: John W.

2009-09-23iwlwifi: reduce noise when skb allocation failsReinette Chatre
Replenishment of receive buffers is done in the tasklet handling received frames as well as in a workqueue. When we are in the tasklet we cannot sleep and thus attempt atomic skb allocations. It is generally not a big problem if this fails since iwl_rx_allocate is always followed by a call to iwl_rx_queue_restock which will queue the work to replenish the buffers at a time when sleeping is allowed. We thus add the __GFP_NOWARN to the skb allocation in iwl_rx_allocate to reduce the noise if such an allocation fails while we still have enough buffers. We do maintain the warning and the error message when we are low on buffers to communicate to the user that there is a potential problem with memory availability on system This addresses issue reported upstream in thread "iwlagn: order 2 page allocation failures" in http://thread.gmane.org/gmane.linux.kernel.wireless.general/39187 Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Acked-by: Mel Gorman <mel@csn.ul.ie> Signed-off-by: John W.

2009-09-23iwlwifi: do not send sync command while holding spinlockReinette Chatre
commit 10c994ca70e8e94bbc85a5bf13de5911ee8de4d2 "iwlwifi: fix remove key error" fixed an error reported by mac80211 during interface down. The fix involved changing an async command to synchronous. Unfortunately this was inside a spinlock section in which we cannot sleep. Modify the sending of the command back to async. This causes the mac80211 error "mac80211-phy0: failed to remove key (0, ff:ff:ff:ff:ff:ff) from hardware (-16)." to return. This error is not serious since this occurs during interface down and the keys will be cleared anyway when ucode is unloaded. Having this error message is thus less serious than a potential deadlock introduced when sleeping while holding a spinlock. We will have to find another fix for that error. This is a revert of the abovementioned commit. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-09-23iwlwifi: disable powersave for 4965Johannes Berg
There's a bug in 4965 powersave that appears to be related to the way it keeps track of its data during sleep, but we haven't found it yet. Due to that, using powersave may spontaneously cause the device to SYSASSERT when transitioning from sleep to wake. Therefore, disable powersave for 4965, until (if ever, unfortunately) we can identify and fix the problem. Cf. http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1982 which was closed, but now has re-appeared with IDLE mode, which probably means we never really fixed it.

2009-09-23iwlwifi: fix potential rx buffer lossReinette Chatre
RX handling maintains a few lists that keep track of the RX buffers. Buffers move from one list to the other as they are used, replenished, and again made available for usage. In one such instance, when a buffer is used it enters the "rx_used" list. When buffers are replenished an skb is attached to the buffer and it is moved to the "rx_free" list. The problem here is that the buffer is first removed from the "rx_used" list _before_ the skb is allocated. Thus, if the skb allocation fails this buffer remains removed from the "rx_used" list and is thus lost for future usage. Fix this by first allocating the skb before trying to attach it to a list. We add an additional check to not do this unnecessarily. Reported-by: Rick Farrington <rickdic@hotmail.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

2009-09-23hostap: Revert a toxic part of the conversion to net_device_opsMartin Decky

Originally, the tx_queue_len was set to 0 for every other interface than HOSTAP_INTERFACE_MASTER, but the new fragment of code sets tx_queue_len to 0 only for HOSTAP_INTERFACE_MASTER. The opposite of the previous behavior makes the driver to drop all packets in AP mode. Change the way 0 is assigned to tx_queue_len according to the original logic.

2009-09-11net: Add DEVTYPE support for Ethernet based devicesMarcel Holtmann
The Ethernet framing is used for a lot of devices these days. Most prominent are WiFi and WiMAX based devices. However for userspace application it is important to classify these devices correctly and not only see them as Ethernet devices. The daemons like HAL, DeviceKit or even NetworkManager with udev support tries to do the classification in userspace with a lot trickery and extra system calls. This is not good and actually reaches its limitations. Especially since the kernel does know the type of the Ethernet device it is pretty stupid. To solve this problem the underlying device type needs to be set and then the value will be exported as DEVTYPE via uevents and available within udev. # cat /sys/class/net/wlan0/uevent DEVTYPE=wlan INTERFACE=wlan0 IFINDEX=5 This is similar to subsystems like USB and SCSI that distinguish between hosts, devices, disks, partitions etc. The new SET_NETDEV_DEVTYPE() is a convenience helper to set the actual device type. All device types are free form, but for convenience the same strings as used with RFKILL are choosen. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: David S.
