2012-06-05mac80211: clean up ieee80211_set_channelJohannes Berg
There's no need for ieee80211_set_channel to check whether a change in configuration happened since ieee80211_hw_config() auto-detects it. Additionally, it's wrong to pretend the HT config for the BSS changed, it didn't, the BSS can't be up & running (AP beaconing etc.) when the channel type is changed anyway.

2012-06-05mac80211: fail authentication when AP denied authenticationEliad Peller
ieee80211_rx_mgmt_auth() doesn't handle denied authentication properly - it authenticates the station and waits for association (for 5 seconds) instead of failing the authentication. Fix it by destroying auth_data and bailing out instead.

2012-06-05mac80211: use offchannel queue only when supportedEliad Peller
Commit 3a25a8c ("mac80211: add improved HW queue control") added support for offchannel queue mapping. However, this mapping is only valid when the driver supports IEEE80211_HW_QUEUE_CONTROL. Check whether the driver supports IEEE80211_HW_QUEUE_CONTROL before setting the hw_queue to the mapped offchannel queue. (This patch doesn't have any actual effect, because hw_queue is overridden in ieee80211_tx() anyway, so this is merely some cleanup) Signed-off-by: Eliad Peller <eliad@wizery.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2012-06-05Bluetooth: Filter duplicated reports in LE scanAndre Guedes
This patch enables filtering duplicated advertising reports during LE scan. Some LE devices advertise using very small intervals generating lots of equal advertising report events to the host. Each event generates a mgmt_device_found event which is copied to userspace. Enabling this feature, duplicated advertising reports are filtered at controller's link layer. This way, the controller doesn't wake up the host to report duplicated advertising reports and, consequently, less data is copied to userspace.

2012-06-05Bluetooth: Change default MTU for L2CAP ATT channelAndre Guedes
This patch changes the default MTU value for L2CAP ATT fixed channel to L2CAP_DEFAULT_MTU (672 octets). Differently from others L2CAP channels, in L2CAP ATT fixed channel there is no MTU negotiation. The MTU value for that channel is up to the L2CAP implementation. The only restriction in L2CAP spec is the MTU value must not be less than 23 octets. At ATT protocol level (on top of L2CAP), we have the ATT_MTU which defines the maximum size of any ATT message sent between client and server. GATT profile defines ATT_MTU default value to 23 octets. If a GATT based profile wants to use ATT_MTU greater than 23 octets (e.g. HID over GATT profile), it should negotiate a new value by executing the GATT Exchange MTU sub-procedure. Thus, in order to support any value of ATT_MTU negotiated at ATT protocol level, our L2CAP implementation should have L2CAP ATT fixed channel MTU equal or greater than ATT_MAX_MTU (512 octets).

2012-06-05Bluetooth: Fix not removing hci_conn for failed LE connectionAndrzej Kaczmarek
This patch changes way LE Connection Complete event with error status are handled. BDADDR returned in such event packet do not need to be valid and should not be used to search for existing hci_conn. Instead, any hci_conn with BT_CONNECT state should be matched since there can be only one pending LE outgoing connection at any time. If not handled properly, appriopriate hci_conn will not be removed and subsequent connection to given peer will try to reuse it without making actual connection attempt. 2012-05-07 11:21:39.133378 < HCI Command: LE Create Connection (0x08|0x000d) plen 25 bdaddr 00:22:D0:10:13:EE type 1 2012-05-07 11:21:39.138774 > HCI Event: Command Status (0x0f) plen 4 LE Create Connection (0x08|0x000d) status 0x00 ncmd 1 2012-05-07 11:21:44.752854 < HCI Command: LE Create Connection Cancel (0x08|0x000e) plen 0 2012-05-07 11:21:44.759475 > HCI Event: Command Complete (0x0e) plen 4 LE Create Connection Cancel (0x08|0x000e) ncmd 1 2012-05-07 11:21:44.764479 > HCI Event: LE Meta Event (0x3e) plen 19 LE Connection Complete status 0x02 handle 0, role master bdaddr 00:00:00:00:00:00 (Public) [14898.739425] [6603] hci_connect: hci0 dst 00:22:D0:10:13:EE [14898.739429] [6603] hci_conn_add: hci0 dst 00:22:D0:10:13:EE [14898.739434] [6603] hci_conn_init_sysfs: conn ffff880079f03000 [14898.739440] [6603] hci_send_cmd: hci0 opcode 0x200d plen 25 [14898.739443] [6603] hci_send_cmd: skb len 28 [14898.739487] [6603] hci_chan_create: hci0 conn ffff880079f03000 ...
