2013-10-18cfg80211: export reg_initiator_name()Luis R. Rodriguez2-10/+26

2013-10-18rt2x00: rt2800lib: autodetect 5GHz band supportGabor Juhos1-4/+4
If the RF chip supports more than 14 channels that indirectly means that it supports the 5GHz band. Use this fact to enable 5GHz band support instead of setting SUPPORT_BAND_5GHZ separately for each RF chip. Also move the setup code of the 2GHz band to the same place.

2013-10-18rt2x00: rt2800lib: use {tx,rx}_chain_num to avoid superfluous EEPROM accessGabor Juhos1-10/+6
The {rx,tx}_chain_num fields of rt2x00dev->default_ant contains the number of RX and TX chains already when the rt2800_probe_hw_mode() function runs. Use those values instead of parsing the EEPROM configuration values again. Signed-off-by: Gabor Juhos <[email protected]> Signed-off-by: John W. Linville <[email protected]>

2013-10-18libertas: move firmware lifetime handling to firmware.cDan Williams5-26/+16
Previously, each bus type was responsible for freeing the firmware structure, but some did that badly. Move responsibility for freeing firmware into firmware.c so that it's done once and correctly, instead of happening in multiple places in bus-specific code. This fixes a use-after-free bug found by Dr. H. Nikolaus Schaller where the SDIO code forgot to NULL priv->helper_fw after freeing it.

2013-10-18Merge tag 'nfc-next-3.13-1' of ↵John W. Linville28-527/+5065
git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-next Samuel Ortiz <[email protected]> says: "This is the first NFC pull request for the 3.13 kernel. It's a fairly big one, with the following highlights: - NFC digital layer implementation: Most NFC chipsets implement the NFC digital layer in firmware, but others have more basic functionalities and expect the host to implement the digital layer. This layer sits below the NFC core. - Sony's port100 support: This is "soft" NFC USB dongle that expects the digital layer to be implemented on the host. This is the first user of our NFC digital stack implementation. - Secure element API: We now provide a netlink API for enabling, disabling and discovering NFC attached (embedded or UICC ones) secure elements. With some userspace help, this allows us to support NFC payments. Only the pn544 driver currently supports that API. - NCI SPI fixes and improvements: In order to support NCI devices over SPI, we fixed and improved our NCI/SPI implementation. The currently most deployed NFC NCI chipset, Broadcom's bcm2079x, supports that mode and we're planning to use our NCI/SPI framework to implement a driver for it. - pn533 fragmentation support in target mode: This was the only missing feature from our pn533 impementation. We now support fragmentation in both Tx and Rx modes, in target mode." Signed-off-by: John W. Linville <[email protected]>

2013-10-18iwlwifi: mvm: fix fw_rx_stats debugfs entryLuciano Coelho1-3/+6
The fw_rx_stats entry in debugfs was getting truncated because the internal buffer used to hold the string was too short. The calculation of the needed buffer size was rather bogus. Simplify the calculation by multiplying the number of entries in the entire structure by the size of each data line and adding the size of the header lines. Additionally, add the mac_id value, which was missing. Signed-off-by: Luciano Coelho <[email protected]> Signed-off-by: Johannes Berg <[email protected]>
2013-10-18iwlwifi: mvm: BT Coex - enable Tx power based on BT statusEmmanuel Grumbach1-2/+2

2013-10-18iwlwifi: mvm: BT Coex - always set mandatory fieldsEmmanuel Grumbach2-3/+11
The firmware always expects the Coex Mode to be set. Moreover, the firmware expects bit 0 is the valid bits to be set all the times. I misunderstood the API and didn't set these bits when commands are sent to update the paramters of the Coex. As a result, the firmware understood that the BT Coex was disabled (Coex mode = 0) and ignored all the updates (valid bit 0 clear). Fix that.

ath10k_wmi_cmd_send() will now sleep if there are no credits available. To make it easier to catch callers in atomic context add might_sleep() to the function. Signed-off-by: Kalle Valo <[email protected]>
2013-10-16ath10k: fix ath10k_bss_assoc() to not sleep in atomic contextKalle Valo1-19/+37
ath10k_bss_assoc() was calling ath10k_peer_assoc(), which can sleep, under atomic rcu_read_lock() and causing scheduing while atomic errors. Workaround that by delaying the call to ath10k_wmi_peer_assoc(). Signed-off-by: Kalle Valo <[email protected]>
2013-10-16ath10k: remove unnecessary checksMichal Kazior1-21/+0
mac80211 interface iteration functions that were used originally iterated over interfaces that weren't re-added to the driver during recovery. Since internal vif list is now used it's safe to remove the safe-guard as internal vif list is based on add/remove_interface function which guarantees that vdev is created in FW before it is iterated over.

2013-10-16ath10k: fix scheduling while atomic config bugMichal Kazior1-84/+62
Recent HTC/WMI changes introduced the bug. ath10k was using _atomic iteration function with sleepable functions. mac80211 provides another iteration function but it cannot be safely called in hw_config() callback due to local->iflist_mtx being possibly acquired already. The patch uses internal vif list for iteration purposes and removes/refactors no longer necessary _iter functions.

2013-10-16ath10k: fix add_interface failure handlingMichal Kazior1-13/+40
If something failed along add_interface() setup it was possible to leak a vdev id, vdev and peer.

2013-10-16ath10k: use workqueue to set WEP TX keyMichal Kazior2-18/+39
Recent WMI/HTC changes made it possible for WMI commands to sleep (if there's not enough HTC TX credits to submit a command). TX path is in an atomic context so calling WMI commands in it is wrong. This simply moves WEP key index update to a worker and fixes the 'scheduling while atomic' bug. This still leaves multiple WEP key handling laggy, i.e. some frames may be TXed with an old/different key (although recipient should still be able to RX them). kvalo: changed the title Signed-off-by: Michal Kazior <[email protected]> Signed-off-by: Kalle Valo <[email protected]>

2013-10-14Bluetooth: Check that scan window is smaller or equal than scan intervalMarcel Holtmann1-0/+4

2013-10-14Bluetooth: Check that bind() bdaddr type matches connect()Johan Hedberg1-0/+6
If a socket was bound to an address type other than BR/EDR (such as LE) we should reject trying to connect it to a BR/EDR address.

2013-10-14Bluetooth: Reject invalid bdaddr types for socketsJohan Hedberg1-0/+6

2013-10-14Bluetooth: Convert Set Discoverable to use an asynchronous requestJohan Hedberg1-9/+54
This patch converts Set Discoverable to use an asynchronous request along with its own completion callback.

2013-10-14Bluetooth: Fix updating scan mode in set_bredr()Johan Hedberg1-1/+5
Now that the connectable setting is also applicable for the LE side it's possible that the HCI_CONNECTABLE flag is already set when changing the BR/EDR setting from false to true while the controller is powered. In this situation we need to update the BR/EDR scan mode to reflect the setting. Additionally, since HCI_CONNECTABLE also applies to LE we must not clear the HCI_CONNECTABLE flag when disabling bredr.

2013-10-14Bluetooth: Move set_bredr_scan() to avoid forward declarationJohan Hedberg1-20/+20

2013-10-14Bluetooth: Make Set Connectable also update the LE advertising typeJohan Hedberg1-5/+30
This patch updates the Set Connectable Management command to also update the LE advertising type to either connectable or non-connectable advertising. An extra helper function is needed for getting the right advertising type since we can not only rely on the HCI_CONNECTABLE flag but must also check for a pending Set Connectable command (in which case the flag does not yet have its final value).
