Bluetooth: Errata Service Release 8, Erratum 3253

2018-10-14T08:25:47Z

L2CAP: New result values 0x0006 - Connection refused – Invalid Source CID 0x0007 - Connection refused – Source CID already allocated As per the ESR08_V1.0.0, 1.11.2 Erratum 3253, Page No. 54, "Remote CID invalid Issue". Applies to Core Specification versions: V5.0, V4.2, v4.1, v4.0, and v3.0 + HS Vol 3, Part A, Section 4.2, 4.3, 4.14, 4.15. Core Specification Version 5.0, Page No.1753, Table 4.6 and Page No. 1767, Table 4.14 New result values are added to l2cap connect/create channel response as 0x0006 - Connection refused – Invalid Source CID 0x0007 - Connection refused – Source CID already allocated Signed-off-by: Mallikarjun Phulari Signed-off-by: Marcel Holtmann

Bluetooth: Use separate L2CAP LE credit based connection result values

2018-10-14T08:24:00Z

Add the result values specific to L2CAP LE credit based connections and change the old result values wherever they were used. Signed-off-by: Mallikarjun Phulari Signed-off-by: Marcel Holtmann

Bluetooth: L2CAP: Derive rx credits from MTU and MPS

2018-09-27T10:52:08Z

Give enough rx credits for a full packet instead of using an arbitrary number which may not be enough depending on the MTU and MPS which can cause interruptions while waiting for more credits, also remove debugfs entry for l2cap_le_max_credits. With these changes the credits are restored after each SDU is received instead of using fixed threshold, this way it is garanteed that there will always be enough credits to send a packet without waiting more credits to arrive.

Bluetooth: L2CAP: Derive MPS from connection MTU

2018-09-27T10:52:08Z

This ensures the MPS can fit in a single HCI fragment so each segment don't have to be reassembled at HCI level, in addition to that also remove the debugfs entry to configure the MPS. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: L2CAP: Fix L2CAP_CR_SCID_IN_USE value

2017-04-12T20:02:37Z

Fix issue found during L2CAP qualification test TP/LE/CFC/BV-20-C. Signed-off-by: Marcin Kraglak Signed-off-by: Marcel Holtmann

Bluetooth: L2CAP: Introduce proper defines for PSM ranges

2016-01-29T10:47:24Z

Having proper defines makes the code a bit readable, it also avoids duplicating hard-coded values since these are also needed when auto-allocating PSM values (in a subsequent patch). Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: L2CAP: Fix returning correct LE CoC response codes

2015-11-05T03:04:00Z

The core spec defines specific response codes for situations when the received CID is incorrect. Add the defines for these and return them as appropriate from the LE Connect Request handler function. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: __l2cap_wait_ack() add defensive timeout

2015-07-23T15:10:51Z

Add a timeout to prevent the do while loop running in an infinite loop. This ensures that the channel will be instructed to close within 10 seconds so prevents l2cap_sock_shutdown() getting stuck forever. Returns -ENOLINK when the timeout is reached. The channel will be subequently closed and not all data will be ACK'ed. Signed-off-by: Dean Jenkins Signed-off-by: Marcel Holtmann

Bluetooth: __l2cap_wait_ack() use msecs_to_jiffies()

2015-07-23T15:10:51Z

Use msecs_to_jiffies() instead of using HZ so that it is easier to specify the time in milliseconds. Also add a #define L2CAP_WAIT_ACK_POLL_PERIOD to specify the 200ms polling period so that it is defined in a single place. Signed-off-by: Dean Jenkins Signed-off-by: Marcel Holtmann

Bluetooth: 6lowpan: Add IPSP PSM value

2014-12-19T10:12:05Z

The Internet Protocol Support Profile a.k.a BT 6LoWPAN specification is ready so PSM value for it is now known. Signed-off-by: Jukka Rissanen Signed-off-by: Marcel Holtmann
