2014-07-23NFC: st21nfcb: Add driver for STMicroelectronics ST21NFCB NFC chipChristophe Ricard
Add driver for STMicroelectronics ST21NFCB NFC controller. ST21NFCB is using NCI protocol and a proprietary low level transport protocol called NDLC used on top. NDLC: The protocol defines 2 types of frame: - One type carrying NCI data (referred as DATAFRAME frames). - One type carrying protocol information used for flow control and error control mechanisms (referred as SUPERVISOR frames). After each frame transmission to the NFC controller, the device host SHALL waitfor an ACK (SUPERVISOR frame) reception before sending a new frame. The NFC controller MAY send a frame at anytime to the device host. The NFC controller MAY send a specific WAIT supervisor frame to indicate to device host that a NCI data packet has been received but that it could take significant time before the NFC controller sends an ACK and thus allows next data reception.

2014-07-21NFC: digital: Add digital framing calls when in target modeMark A. Greer
Add new "NFC_DIGITAL_FRAMING_*" calls to the digital layer so the driver can make the necessary adjustments when performing anticollision while in target mode. The driver must ensure that the effect of these calls happens after the following response has been sent but before reception of the next request begins.

2014-07-21NFC: digital: Clear poll_tech_count before activating targetMark A. Greer
Currently, digital_target_found() has a race between the events started by calling nfc_targets_found() (which ultimately expect ddev->poll_tech_count to be zero) and setting ddev->poll_tech_count to zero after the call to nfc_targets_found(). When the race is "lost" (i.e., ddev->poll_tech_count is found to not be zero by the events started by nfc_targets_found()), an error message is printed and the target is not found. A similar race exists when digital_tg_recv_atr_req() calls nfc_tm_activated(). Fix this by first saving the current value of ddev->poll_tech_count and then clearing it before calling nfc_targets_found()/nfc_tm_activated(). Clearing ddev->poll_tech_count before calling nfc_targets_found()/nfc_tm_activated() eliminates the race. Saving the value is required so it can be restored when nfc_targets_found()/nfc_tm_activated() fails and polling needs to continue.

2014-07-21NFC: digital: Check for NFC-DEP before checking for Type 4 tagMark A. Greer
In digital_in_recv_sel_res(), the code that determines the tag type will interpret bits 7:6 (lsb being b1 as per the Digital Specification) of a SEL RES set to 11b as a Type 4 tag. This is okay except that the neard will interpret the same value as an NFC-DEP device (in src/tag.c:set_tag_type() in the neard source). Make the digital layer's interpretation match neard's interpretation by changing the order of the checks in digital_in_recv_sel_res() so that a value of 11b in bits 7:6 is interpreted as an NFC-DEP device instead of a Type 4 tag.

2014-07-18mwifiex: do not re-associate when already connectedUjjal Roy
In managed mode if the driver is getting a re-associate command from cfg80211, driver deauthenticates with the AP internally and sends a disconnected event to cfg80211 before completion of its association process. The disconnected event then modifies the SSID length as wdev->ssid_len = 0. So, upon receiving the connect result event from driver, cfg80211 is unable to get that BSS from the device's BSS list and generates the following WARN_ON message. WARNING: CPU: 0 PID: 857 at net/wireless/sme.c:658 __cfg80211_connect_result+0x3a6/0x3e0 [cfg80211]() Avoid re-association while the device is already associated to a network.

2014-07-18ath9k: fix pending tx frames accountingFelix Fietkau
Packets originally buffered for the regular hardware tx queues can end up being transmitted through the U-APSD queue (via PS-Poll or U-APSD). When packets are dropped due to retransmit failures, the pending frames counter is not always updated properly. Fix this by keeping track of the queue that a frame was accounted for in the ath_frame_info struct, and using that on completion to decide whether the counter should be updated. This fixes some spurious transmit queue hangs. Cc: stable@vger.kernel.org Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2014-07-15brcmfmac: rework wiphy structure setupArend van Spriel
Instead of waiting for IFF_UP of the primary net device to determine the band and channel information of the wiphy structure, this is now done during driver initialization in brcmf_cfg80211_attach(). The channel information is obtained from the device and the 2G band is updated when 40MHz bandwidth is enabled for that band. Before this change the band and channel objects were common between multiple brcmfmac devices in the system, which make that information rather unreliable. That is also fixed with this reworked implementation.

Reworked the debugfs functions in the driver making it easier for other driver parts to add a debugfs entry and keeping the information they want to expose in debugfs private, ie. not in a header. This is accomplished by providing the function brcmf_debugfs_add_entry() in which the caller provides a read function in which they provide the content. The debugfs function will take care of creating the debugfs entry and cleaning up upon removal.
