2012-09-25NFC: Remove crc generation from shdlc layerWaldemar Rymarkiewicz1-25/+2
Checksum is specific for a chip spcification and it varies (in size and type) between different hardware. It should be handled in the driver then. Moreover, shdlc spec doesn't mention crc as a part of the frame. Update pn544_hci driver as well.

2012-09-25NFC: Use system_nrt_wq instead of custom onesTejun Heo6-118/+26
NFC is using a number of custom ordered workqueues w/ WQ_MEM_RECLAIM. WQ_MEM_RECLAIM is unnecessary unless NFC is gonna be used as transport for storage device, and all use cases match one work item to one ordered workqueue - IOW, there's no actual ordering going on at all and using system_nrt_wq gives the same behavior. There's nothing to be gained by using custom workqueues. Use system_nrt_wq instead and drop all the custom ones.

2012-09-18Bluetooth: Update management interface revisionJohan Hedberg1-1/+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.

2012-09-14mac80211: allow re-open the blocked peer link in meshChun-Yeow Yeoh1-1/+2
Peer link which is blocked using the "iw mesh0 station set <MAC addr> plink_action block" is previously not able to re-open using "iw mesh0 station set <MAC addr> plink_action open". This patch is intended to solve this. If the station plink state remains at OPN_SNT once open, try block and open again should solve this problem.

2012-09-14mac80211: handle power constraint/country IE betterJohannes Berg3-22/+72
Currently, mac80211 uses the power constraint IE, and reduces the regulatory max TX power by it. 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.

2012-09-11mac80211: remove unneeded CONFIG_PM ifdefJohannes Berg1-13/+0

2012-09-10mac80211: validate skb->dev in the tx status pathFelix Fietkau1-18/+30
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.

2012-09-10mac80211: use call_rcu() on sta deletionEliad Peller3-57/+81
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().

2012-09-10mac80211: add key flag for management keysJohannes Berg2-1/+33
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.
