Most probably a typo, the check should have been for BT_SK_DEFER_SETUP instead of BT_DEFER_SETUP (which right now only represents a socket option). Signed-off-by:

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. Signed-off-by:

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).

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 ...

Make A2MP channel special channel which do not reference hci_conn. This prevents from keeping ACL connection open when all L2CAP channels got closed. hci_conn_hold and hci_conn_put are not reference counts on the hci_conn structure in the typical way. They are reference counts for the ACL. When you do the last hci_conn_put, the ACL is disconnected after a timeout. Reported-by:
