2012-08-15Bluetooth: L2CAP - Fix info leak via getsockname()Mathias Krause1-0/+1
The L2CAP code fails to initialize the l2_bdaddr_type member of struct sockaddr_l2 and the padding byte added for alignment. It that for leaks two bytes kernel stack via the getsockname() syscall. Add an explicit memset(0) before filling the structure to avoid the info leak.

2012-08-06Bluetooth: Fix legacy pairing with some devicesSzymon Janc2-1/+7
Some devices e.g. some Android based phones don't do SDP search before pairing and cancel legacy pairing when ACL is disconnected. PIN Code Request event which changes ACL timeout to HCI_PAIRING_TIMEOUT is only received after remote user entered PIN. In that case no L2CAP is connected so default HCI_DISCONN_TIMEOUT (2 seconds) is being used to timeout ACL connection. This results in problems with legacy pairing as remote user has only few seconds to enter PIN before ACL is disconnected. Increase disconnect timeout for incomming connection to HCI_PAIRING_TIMEOUT if SSP is disabled and no linkey exists. To avoid keeping ACL alive for too long after SDP search set ACL timeout back to HCI_DISCONN_TIMEOUT when L2CAP is connected. 2012-07-19 13:24:43.413521 < HCI Command: Create Connection (0x01|0x0005) plen 13 bdaddr 00:02:72:D6:6A:3F ptype 0xcc18 rswitch 0x01 clkoffset 0x0000 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 2012-07-19 13:24:43.425224 > HCI Event: Command Status (0x0f) plen 4 Create Connection (0x01|0x0005) status 0x00 ncmd 1 2012-07-19 13:24:43.885222 > HCI Event: Role Change (0x12) plen 8 status 0x00 bdaddr 00:02:72:D6:6A:3F role 0x01 Role: Slave 2012-07-19 13:24:44.054221 > HCI Event: Connect Complete (0x03) plen 11 status 0x00 handle 42 bdaddr 00:02:72:D6:6A:3F type ACL encrypt 0x00 2012-07-19 13:24:44.054313 < HCI Command: Read Remote Supported Features (0x01|0x001b) plen 2 handle 42 2012-07-19 13:24:44.055176 > HCI Event: Page Scan Repetition Mode Change (0x20) plen 7 bdaddr 00:02:72:D6:6A:3F mode 0 2012-07-19 13:24:44.056217 > HCI Event: Max Slots Change (0x1b) plen 3 handle 42 slots 5 2012-07-19 13:24:44.059218 > HCI Event: Command Status (0x0f) plen 4 Read Remote Supported Features (0x01|0x001b) status 0x00 ncmd 0 2012-07-19 13:24:44.062192 > HCI Event: Command Status (0x0f) plen 4 Unknown (0x00|0x0000) status 0x00 ncmd 1 2012-07-19 13:24:44.067219 > HCI Event: Read Remote Supported Features (0x0b) plen 11 status 0x00 handle 42 Features: 0xbf 0xfe 0xcf 0xfe 0xdb 0xff 0x7b 0x87 2012-07-19 13:24:44.067248 < HCI Command: Read Remote Extended Features (0x01|0x001c) plen 3 handle 42 page 1 2012-07-19 13:24:44.071217 > HCI Event: Command Status (0x0f) plen 4 Read Remote Extended Features (0x01|0x001c) status 0x00 ncmd 1 2012-07-19 13:24:44.076218 > HCI Event: Read Remote Extended Features (0x23) plen 13 status 0x00 handle 42 page 1 max 1 Features: 0x01 0x00 0x00 0x00 0x00 0x00 0x00 0x00 2012-07-19 13:24:44.076249 < HCI Command: Remote Name Request (0x01|0x0019) plen 10 bdaddr 00:02:72:D6:6A:3F mode 2 clkoffset 0x0000 2012-07-19 13:24:44.081218 > HCI Event: Command Status (0x0f) plen 4 Remote Name Request (0x01|0x0019) status 0x00 ncmd 1 2012-07-19 13:24:44.105214 > HCI Event: Remote Name Req Complete (0x07) plen 255 status 0x00 bdaddr 00:02:72:D6:6A:3F name 'uw000951-0' 2012-07-19 13:24:44.105284 < HCI Command: Authentication Requested (0x01|0x0011) plen 2 handle 42 2012-07-19 13:24:44.111207 > HCI Event: Command Status (0x0f) plen 4 Authentication Requested (0x01|0x0011) status 0x00 ncmd 1 2012-07-19 13:24:44.112220 > HCI Event: Link Key Request (0x17) plen 6 bdaddr 00:02:72:D6:6A:3F 2012-07-19 13:24:44.112249 < HCI Command: Link Key Request Negative Reply (0x01|0x000c) plen 6 bdaddr 00:02:72:D6:6A:3F 2012-07-19 13:24:44.115215 > HCI Event: Command Complete (0x0e) plen 10 Link Key Request Negative Reply (0x01|0x000c) ncmd 1 status 0x00 bdaddr 00:02:72:D6:6A:3F 2012-07-19 13:24:44.116215 > HCI Event: PIN Code Request (0x16) plen 6 bdaddr 00:02:72:D6:6A:3F 2012-07-19 13:24:48.099184 > HCI Event: Auth Complete (0x06) plen 3 status 0x13 handle 42 Error: Remote User Terminated Connection 2012-07-19 13:24:48.179182 > HCI Event: Disconn Complete (0x05) plen 4 status 0x00 handle 42 reason 0x13 Reason: Remote User Terminated Connection Cc: stable@vger.kernel.org Signed-off-by: Szymon Janc <szymon.janc@tieto.com> Acked-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

2012-07-16Bluetooth: Change page scan interval in fast connectable modeJohan Hedberg1-2/+2
This patch is based on a user space (hciops) patch which never made it upstream but does make sense to include in the mgmt part of the kernel. (User space) commit message from Dmitriy Paliy: " Page scan interval in fast connectable mode is changed from 22.5 msec to 160 msec to perform less aggressive page scanning. This is done accordingly to controller vendor recommendation. Primary concern is that current parameters 22.5 interval, 11.25 window, and interleaved scanning occupy whole radio bandwidth. Changing interval to 160 msec should be sufficient for both speeding up connection establishment and leaving space for other activities, like inquiry scan, e.g. " Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
2012-07-15Bluetooth: Use tx window from config response for ack timingMat Martineau1-25/+34
This change addresses an L2CAP ERTM throughput problem when a remote device does not fully utilize the available transmit window. The L2CAP ERTM transmit window size determines the maximum number of unacked frames that may be outstanding at any time. It is configured separately for each direction of an ERTM connection. Each side sends a configuration request with a tx_win field indicating how many unacked frames it is capable of receiving before sending an ack. The configuration response's tx_win field shows how many frames the transmitter will actually send before waiting for an ack. It's important to trace both the actual transmit window (to check for validity of incoming frames) and the number of frames that the transmitter will send before waiting (to send acks at the appropriate time). Now there are separate tx_win and ack_win values. ack_win is updated based on configuration responses, and is used to determine when acks are sent.

2012-06-25HID: Fix the generic Kconfig optionsHenrik Rydberg1-1/+1
The generic HID driver is obviously not a special driver, so move it outside of the special drivers menu. Explain the usage and make the default follow the HID setting. This should simplify migration from older kernels. While at it, remove the redundant HID_SUPPORT option and modify the HID and USB_HID entries to better explain the bus structure.

2012-06-14Bluetooth: Fix sending HCI_Disconnect only when connectedVishal Agarwal1-1/+1
HCI_Disconnect should only be sent after connection is established. If connection is not yet established and HCI_Disconnect is called then disconnection complete will be received with a handle which does not exist and hence this event will be ignored. But as mgmt.c will not receive this event, its variable for pending command is not cleared.This will result in future Disconnect commands for that BD Address to be blocked with error busy.
