2012-09-27NFC: Fix sleeping in invalid context when netlink socket is closedSzymon Janc1-7/+39
netlink_register_notifier requires notify functions to not sleep. nfc_stop_poll locks device mutex and must not be called from notifier. Create workqueue that will handle this for all devices.

2012-09-27NFC: LLCP raw socket supportThierry Escande5-4/+148
This adds support for socket of type SOCK_RAW to LLCP. sk_buff are copied and sent to raw sockets with a 2 bytes extra header: The first byte header contains the nfc adapter index. The second one contains flags: - 0x01 - Direction (0=RX, 1=TX) - 0x02-0x80 - Reserved A raw socket has to be explicitly bound to a nfc adapter. This is achieved by specifying the adapter index to be bound to in the dev_idx field of the sockaddr_nfc_llcp struct passed to bind().

2012-09-25ath9k_hw: fix BT sleep state on chip wakeupRajkumar Manoharan1-1/+1
Whenever both WLAN and BT in/out sleep mode, sometimes WLAN is not able to take back the shared LNA control after resumes from sleep mode. The idea is that for WLAN to check if BT owns LNA control and BT is in sleep mode when WLAN just resumes from sleep mode. If the condition is true, do a BTCOEX_RC_WARM_RESET for WLAN to take back the control of shared LNA. Now the issue is the BT sleep value read from MCI register is overlooked by assigning u32 into u8. Hence the above condition never be met so that WLAN used to report beacon losses and frequent connection drops.

2012-09-25ath9k: Disable ASPM only for AR9285Sujith Manoharan1-2/+3
Currently, ASPM is disabled for all WLAN+BT combo chipsets when BTCOEX is enabled. This is incorrect since the workaround is required only for WB195, which is a AR9285+AR3011 combo solution. Fix this by checking for the HW version when enabling the workaround.

git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-3.0 So says Samuel Ortiz <sameo@linux.intel.com>: This is the first NFC pull request for the 3.7 merge window. With this one we get: - HCI and LLC layers separation. We now can support various LLC protocols for HCI drivers, SHDLC being one of them. This will be needed as we're planning to support raw HCI chipsets that do the SHDLC encapsulation in firmware. So for now we have an SHDLC and a NOP LLC layers. - pn533 command queueing implementation. This simplifies the pn533 locking logic and fixes a kernel warning. - NCI p2p initiator mode implementation. - Replace custom workqueues with system ones, for HCI and LLCP. - Raw pn544 driver removal, as scheduled on the features-removal.txt file. - A few HCI, SHDLC and LLCP fixes.

2012-09-25cfg80211: Fix regulatory check for 60GHz band frequenciesVladimir Kondratiev1-5/+14
The current regulatory code on cfg80211 performs a check to see if a regulatory rule belongs to an IEEE band so that if a Country IE is received and no rules are specified for a band (which is allowed by IEEE) those bands are left intact. The current band check assumes a rule is bound to a band if the rule's start or end frequency is less than 2 GHz apart from the center of frequency being inspected. In order to support 60 GHz for 802.11ad we need to increase this to account for the channel spacing of 2160 MHz whereby a channel somewhere in the middle of a regulatory rule may be more than 2 GHz apart from either the beginning or end of the frequency rule. Without a fix for this even though channels 1-3 are allowed world wide on the rule (57240 - 63720 @ 2160), channel 2 at 60480 MHz will end up getting disabled given that it is 3240 MHz from both the frequency rule start and end frequency. Fix this by using 2 GHz separation assumption for the 2.4 and 5 GHz bands but for 60 GHz use a 10 GHz separation before assuming a rule is not part of the band. Since we have no 802.11ad drivers yet merged this change has no impact to existing Linux upstream device drivers. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Acked-by: Luis R.

During processing incoming RSET frame chip, possibly due to its internal timout, can retrnasmit an another RSET which is next queued for processing in shdlc layer. In case when we accept processed RSET skip those remaining on the rcv queue until chip will send it's first S or I frame. This will mean the chip completed connection as well.

2012-09-25NFC: xmit from hci ops must return 0 or negativeWaldemar Rymarkiewicz2-2/+11
xmit callback provided by a driver encapsulates upper layers data and sends it to the hardware. So, HCI does not know the exact amount of data being sent and thus can't handle partially sent frames properly. Therefore, the driver must return 0 for completely sent frame or negative for failure.

Instead of returning EBUSY when getting a command while another one is running, we queue them. Upon completion of the pending command, the next one is processed. Besides the fact that it simplifies the pn533 locking scheme, it also comes with the nice side effect of fixing the following warning: [ 82.274297] ===================================== [ 82.274297] [ BUG: bad unlock balance detected! ] [ 82.274298] 3.5.0-rc1+ #1 Not tainted [ 82.274299] ------------------------------------- [ 82.274300] kworker/u:1/16 is trying to release lock (&dev->cmd_lock) at: [ 82.274305] [<ffffffff8144f246>] mutex_unlock+0x9/0xb [ 82.274305] but there are no more locks to release!

2012-09-24ath5k: disable HW crypto in management frameChun-Yeow Yeoh2-0/+4
Hardware support for MFP is not available in ath5k. Thus, this implementation allows the mac80211 stack to do the actuall crypto operation. Signed-off-by: Chun-Yeow Yeoh <yeohchunyeow@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-09-24carl9170: connect to 11w protected networksChristian Lamparter2-1/+4
Previously, it was not possible to connect to networks which requires 11w to be supported by the stations. While the documentation hints that there's some hardware support for offloading MFP "decryption", this simple implementation relies on the mac80211 stack to do the actual crypto operations.

2012-09-24p54: connect to 11w protected networksChristian Lamparter1-0/+12
Previously, it was not possible to connect to networks which requires 11w to be supported by the stations. Note: As all current (and old) firmwares corrupt incoming, protected management frames, the decryption offloading needs to be disabled. This will be done automatically if needed.
