| * Bluetooth: Update management interface revisionJohan Hedberg2012-09-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For each kernel release where commands or events are added to the management interface, the revision field should be increment by one. The increment should only happen once per kernel release and not for every command/event that gets added. The revision value is for informational purposes only, but this simple policy would make any future debugging a lot simple.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MGMT_EV_DEVICE_DISCONNECTED will now expose the disconnection reason to userland, distinguishing four possible values: 0x00 Reason not known or unspecified 0x01 Connection timeout 0x02 Connection terminated by local host 0x03 Connection terminated by remote host Note that the local/remote distinction just determines which side terminated the low-level connection, regardless of the disconnection of the higher-level profiles. This can sometimes be misleading and thus must be used with care. For example, some hardware combinations would report a locally initiated disconnection even if the user turned Bluetooth off in the remote side.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of allocating one big chunk of DMA-coherent memory for the firmware and keeping it around, only vmalloc() the firmware and copy it into a single page of DMA-coherent memory for the upload. The advantage is that we don't need DMA memory for the firmware image that is stored while the driver is operating, we only need it while uploading. This will make it easier for the driver to work if the system has fragmented memory. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

This can cause issues if the AP is advertising a large power constraint value matching a high TX power in its country IE, for example in this case: ... Country: US Environment: Indoor/Outdoor ... Channels [157 - 157] @ 30 dBm ... Power constraint: 13 dB ... What happened here is that our local regulatory TX power is 15 dBm, and gets reduced by 13 dB so we end up with only 2 dBm effective TX power, which is way too low. Instead, handle the country IE/power constraint IE combined and restrict our TX power to the max of the regulatory power and the maximum power advertised by the AP, in this case 17 dBm (= 30 dBm - 13 dB). Also print a message when this happens to let the user know and help us debug issues with it. Reported-by: Carl A. Cook <CACook@quantum-equities.com> Tested-by: Carl A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The functions are only called if CONFIG_PM is set as the callers are under an ifdef, so there's no need to also define no-op functions. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | skb->dev might contain a stale reference to a device that was already deleted, and using it unchecked can lead to invalid pointer accesses. Since this is only used for nl80211 tx, iterate over active interfaces to find a match for skb->dev, and discard the tx status if the device is gone.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mac80211 calls synchronize_rcu() on sta deletion, which increase the roaming time significantly. Convert it into a call_rcu() mechanism, in order to avoid blocking. Since some of the cleanup functions might sleep, schedule from the call_rcu callback a new work that will do the actual cleanup. In order to make sure the cleanup occurs before the interface went down, flush local->workqueue on ieee80211_do_stop().

| * | | mac80211: add key flag for management keysJohannes Berg2012-09-106-6/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mark keys that might be used to receive management frames so drivers can fall back on software crypto for them if they don't support hardware offload. As the new flag is only set correctly for RX keys and the existing IEEE80211_KEY_FLAG_SW_MGMT flag can only affect TX, also rename the latter to IEEE80211_KEY_FLAG_SW_MGMT_TX.

| * | | mac80211: reply to AUTH with DEAUTH if sta allocation fails in IBSSAntonio Quartulli2012-09-071-1/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever a host gets an AUTH frame it first allocates a new station and then replies with another AUTH frame. However, if sta allocations fails the host should send a DEAUTH frame instead to tell the other end that something went wrong.
