2011-12-21Bluetooth: Always compile SCO and L2CAP in Bluetooth CoreUlisses Furquim
The handling of SCO audio links and the L2CAP protocol are essential to any system with Bluetooth thus are always compiled in from now on.

2011-12-19Bluetooth: Add missing mgmt_confirm_name command definitionJohan Hedberg
This patch adds the necessary structs for the Confirm Name command. This ensures that the protocol definitions are up to date with the latest mgmt specification.

2011-12-19Bluetooth: Fix mgmt_(block,unblock)_device opcodesJohan Hedberg
This patch fixes the opcodes of the Block/Unblock device commands to match with what user-space expects and to confirm with the latest mgmt specification. The reason the values were wrong was a missing Confirm Name command definition (which will be added by a subsequent patch).

2011-12-19Bluetooth: Add missing confirm_name field to mgmt_ev_device_foundJohan Hedberg
This patch adds a missing confirm_name field to mgmt_ev_device_found. Support for setting the correct value for this field is not implemented yet, but having it part of the struct definition ensures that user-space gets correct sized device_found events and is thereby able to do at least rudimentary parsing of them.

2011-12-18Bluetooth: Add timer for automatically disabling the service cacheJohan Hedberg
We do not want the service cache to be enabled indefinitely after mgmt_read_info is called. To solve this a timer is added which will automatically disable the cache if mgmt_set_dev_class isn't called within 5 seconds of calling mgmt_read_info.

2011-12-18Bluetooth: Remove mgmt_set_service_cacheJohan Hedberg
Instead of having an explicit service cache command we can make the mgmt API simpler by implicitly enabling the cache when mgmt_read_info is called for the first time and disabling it when mgmt_set_dev_class is called.

2011-12-16cfg80211: allow following country IE power for custom regdom cardsLuis R. Rodriguez
By definition WIPHY_FLAG_STRICT_REGULATORY was intended to allow the wiphy to adjust itself to the country IE power information if the card had no regulatory data but we had no way to tell cfg80211 that if the card also had its own custom regulatory domain (these are typically custom world regulatory domains) that we want to follow the country IE's noted values for power for each channel. We add support for this and document it. This is not a critical fix but a performance optimization for cards with custom regulatory domains that associate to an AP with sends out country IEs with a higher EIRP than the one on the custom regulatory domain. In practice the only driver affected right now are the Atheros drivers as they are the only drivers using both WIPHY_FLAG_STRICT_REGULATORY and WIPHY_FLAG_CUSTOM_REGULATORY -- used on cards that have an Atheros world regulatory domain. Cards that have been programmed to follow a country specifically will not follow the country IE power. So although not a stable fix distributions should consider cherry picking this.

2011-12-15cfg80211: validate nl80211 station handling betterJohannes Berg
The nl80211 station handling code is a bit messy and doesn't do a lot of validation. It seems like this could be an issue for drivers that don't use mac80211 to validate everything. As cfg80211 doesn't keep station state, move the validation of allowing supported_rates to change for TDLS only in station mode to mac80211.

2011-12-14NFC: Initial LLCP supportSamuel Ortiz
This patch is an initial implementation for the NFC Logical Link Control protocol. It's also known as NFC peer to peer mode. This is a basic implementation as it lacks SDP (services Discovery Protocol), frames aggregation support, and frame rejecion parsing. Follow up patches will implement those missing features.

2011-12-14NFC: Set and get DEP general bytesSamuel Ortiz

2011-12-13cfg80211: Fix race in bss timeoutVasanthakumar Thiagarajan
It is quite possible to run into a race in bss timeout where the drivers see the bss entry just before notifying cfg80211 of a roaming event but it got timed out by the time rdev->event_work got scehduled from cfg80211_wq. This would result in the following WARN-ON() along with the failure to notify the user space of the roaming. The other situation which is happening with ath6kl that runs into issue is when the driver reports roam to same AP event where the AP bss entry already got expired. To fix this, move cfg80211_get_bss() from __cfg80211_roamed() to cfg80211_roamed().

2011-12-06mac80211: accept public action frames with mismatched BSSIDJohannes Berg
Arik's patch "mac80211: allow action frames with unknown BSSID in GO mode" allowed any action frames in P2P mode to go through, but only to cooked monitor interfaces as the IEEE80211_RX_RA_MATCH was still cleared. As a result my no-monitor patches broke invitation responses. Instead of allowing any action frames in P2P GO mode to go through with a wrong BSSID like that patch did, allow all public action frames.
