2020-02-28Bluetooth: Remove adv set for directed advertisingSathish Narsimman
Extended advertising Data is set during bluetooth initialization by default which causes InvalidHCICommandParameters when setting Extended advertising parameters. As per Core Spec 5.2 Vol 2, PART E, Sec 7.8.53, for advertising_event_property LE_LEGACY_ADV_DIRECT_IND does not supports advertising data when the advertising set already contains some, the controller shall return erroc code 'InvalidHCICommandParameters(0x12).

2020-02-28Bluetooth: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2019-05-05Bluetooth: Ignore CC events not matching the last HCI commandJoão Paulo Rechi Vita
This commit makes the kernel not send the next queued HCI command until a command complete arrives for the last HCI command sent to the controller. This change avoids a problem with some buggy controllers (seen on two SKUs of QCA9377) that send an extra command complete event for the previous command after the kernel had already sent a new HCI command to the controller. The problem was reproduced when starting an active scanning procedure, where an extra command complete event arrives for the LE_SET_RANDOM_ADDR command. When this happends the kernel ends up not processing the command complete for the following commmand, LE_SET_SCAN_PARAM, and ultimately behaving as if a passive scanning procedure was being performed, when in fact controller is performing an active scanning procedure. This makes it impossible to discover BLE devices as no device found events are sent to userspace. This problem is reproducible on 100% of the attempts on the affected controllers. The extra command complete event can be seen at timestamp 27.420131 on the btmon logs bellow.

2019-01-22Bluetooth: Fix locking in bt_accept_enqueue() for BH contextMatthias Kaehlcke
With commit e16337622016 ("Bluetooth: Handle bt_accept_enqueue() socket atomically") lock_sock[_nested]() is used to acquire the socket lock before manipulating the socket. lock_sock[_nested]() may block, which is problematic since bt_accept_enqueue() can be called in bottom half context (e.g. from rfcomm_connect_ind()): [<ffffff80080d81ec>] __might_sleep+0x4c/0x80 [<ffffff800876c7b0>] lock_sock_nested+0x24/0x58 [<ffffff8000d7c27c>] bt_accept_enqueue+0x48/0xd4 [bluetooth] [<ffffff8000e67d8c>] rfcomm_connect_ind+0x190/0x218 [rfcomm] Add a parameter to bt_accept_enqueue() to indicate whether the function is called from BH context, and acquire the socket lock with bh_lock_sock_nested() if that's the case. Also adapt all callers of bt_accept_enqueue() to pass the new parameter: - l2cap_sock_new_connection_cb() - uses lock_sock() to lock the parent socket => process context - rfcomm_connect_ind() - acquires the parent socket lock with bh_lock_sock() => BH context - __sco_chan_add() - called from sco_chan_add(), which is called from sco_connect(). parent is NULL, hence bt_accept_enqueue() isn't called in this code path and we can ignore it - also called from sco_conn_ready(). uses bh_lock_sock() to acquire the parent lock => BH context Fixes: e16337622016 ("Bluetooth: Handle bt_accept_enqueue() socket atomically") Signed-off-by: Matthias Kaehlcke <mka@chromium.org> Reviewed-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Cc: stable@vger.kernel.org

This event comes after connection complete event for incoming connections. Since we now have different random address for each instance, conn resp address is assigned from this event. As of now only connection part is handled as we are not enabling duration or max num of events while starting ext adv.

2018-07-30Bluetooth: Implement Set ADV set random addressJaganath Kanakkassery
This basically sets the random address for the adv instance Random address can be set only if the instance is created which is done in Set ext adv param. Random address and rpa expire timer and flags have been added to adv instance which will be used when the respective instance is scheduled. This introduces a hci_get_random_address() which returns the own address type and random address (rpa or nrpa) based on the instance flags and hdev flags. New function is required since own address type should be known before setting adv params but address can be set only after setting params. < HCI Command: LE Set Advertising Set Random Address (0x08|0x0035) plen 7 Advertising handle: 0x00 Advertising random address: 3C:8E:56:9B:77:84 (OUI 3C-8E-56) > HCI Event: Command Complete (0x0e) plen 4 LE Set Advertising Set Random Address (0x08|0x0035) ncmd 1 Status: Success (0x00) Signed-off-by: Jaganath Kanakkassery <jaganathx.kanakkassery@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2018-07-30Bluetooth: Impmlement extended adv enableJaganath Kanakkassery
This patch basically replaces legacy adv with extended adv based on the controller support. Currently there is no design change. ie only one adv set will be enabled at a time. This also adds tx_power in instance and store whatever returns from Set_ext_parameter, use the same in adv data as well. For instance 0 tx_power is stored in hdev only. < HCI Command: LE Set Extended Advertising Parameters (0x08|0x0036) plen 25 Handle: 0x00 Properties: 0x0010 Use legacy advertising PDUs: ADV_NONCONN_IND Min advertising interval: 1280.000 msec (0x0800) Max advertising interval: 1280.000 msec (0x0800) Channel map: 37, 38, 39 (0x07) Own address type: Random (0x01) Peer address type: Public (0x00) Peer address: 00:00:00:00:00:00 (OUI 00-00-00) Filter policy: Allow Scan Request from Any, Allow Connect Request from Any (0x00) TX power: 127 dbm (0x7f) Primary PHY: LE 1M (0x01) Secondary max skip: 0x00 Secondary PHY: LE 1M (0x01) SID: 0x00 Scan request notifications: Disabled (0x00) > HCI Event: Command Complete (0x0e) plen 5 LE Set Extended Advertising Parameters (0x08|0x0036) ncmd 1 Status: Success (0x00) TX power (selected): 7 dbm (0x07) < HCI Command: LE Set Extended Advertising Enable (0x08|0x0039) plen 6 Extended advertising: Enabled (0x01) Number of sets: 1 (0x01) Entry 0 Handle: 0x00 Duration: 0 ms (0x00) Max ext adv events: 0 > HCI Event: Command Complete (0x0e) plen 4 LE Set Extended Advertising Enable (0x08|0x0039) ncmd 2 Status: Success (0x00) Signed-off-by: Jaganath Kanakkassery <jaganathx.kanakkassery@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
