2018-10-14Bluetooth: Remove redundant check on statusColin Ian King1-21/+17
The check on status is redundant as a status has to be zero at the point it is being checked because of a previous check and return path via label 'unlock'. Remove the redundant check and the deadcode that can never be reached. Detected by CoverityScan, CID#1471710 ("Logically dead code") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2018-07-30Bluetooth: Handle ADv set terminated eventJaganath Kanakkassery1-3/+40
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 Kanakkassery1-1/+36
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 Kanakkassery1-0/+72
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.

2016-07-09Bluetooth: Rename HCI_BREDR into HCI_PRIMARYMarcel Holtmann1-1/+1
The HCI_BREDR naming is confusing since it actually stands for Primary Bluetooth Controller. Which is a term that has been used in the latest standard. However from a legacy point of view there only really have been Basic Rate (BR) and Enhanced Data Rate (EDR). Recent versions of Bluetooth introduced Low Energy (LE) and made this terminology a little bit confused since Dual Mode Controllers include BR/EDR and LE. To simplify this the name HCI_PRIMARY stands for the Primary Controller which can be a single mode or dual mode controller.

Doing the page scan updates through the req_workqueue ensures that the state changes are performed in a race-free manner.

So it makes more sense to actually rename it into bt_cb()->hci and also call it then struct hci_ctrl. In addition that allows moving the decoded opcode for outgoing packets into that struct. So far it was just consuming valuable space from the main shared items. And opcode are not valid for L2CAP packets.

We can't use hci_explicit_connect_lookup() since that would only cover explicit connections, leaving normal reconnections completely untouched. Not using it in turn means leaving out entries in pend_le_reports. To fix this and simplify the logic move conn params from the reports list to the pend_le_conns list for the duration of an explicit connect. Once the connect is complete move the params back to the pend_le_reports list. This also means that the explicit connect lookup function only needs to look into the pend_le_conns list.

When disable/enable scan command is issued twice, some controllers will return an error for the second request, i.e. requests with this command will fail on some controllers, and succeed on others. This patch makes sure that unnecessary scan disable/enable commands are not issued. When adding device to the auto connect whitelist when there is pending connect attempt, there is no need to update scan. hci_connect_le_scan_cleanup is conditionally executing hci_conn_params_del, that is calling hci_update_background_scan. Make the other case also update scan, and remove reduntand call from hci_connect_le_scan_remove. When stopping interleaved discovery the state should be set to stopped only when both LE scanning and discovery has stopped.

Currently, when trying to connect to already paired device that just rotated its RPA MAC address, old address would be used and connection would fail. In order to fix that, kernel must scan and receive advertisement with fresh RPA before connecting. This path makes sure that after advertisement is received from device that we try to connect to, it is properly handled in check_pending_le_conn and trigger connect attempt. It also modifies hci_le_connect to make sure that connect attempt will be properly continued.

2015-06-12Bluetooth: Remove redundant check for ACL_LINKJohan Hedberg1-2/+1
The encryption key size is read only for BR/EDR (ACL_LINK) connections so there's no need to check for it in the read_enc_key_size_complete() callback. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-06-12Bluetooth: Read encryption key size for BR/EDR connectionsJohan Hedberg1-0/+87
Since Bluetooth 3.0 there's a HCI command available for reading the encryption key size of an BR/EDR connection. This information is essential e.g. for generating an LTK using SMP over BR/EDR, so store it as part of struct hci_conn.

2015-06-12Bluetooth: Move SC-only check outside of BT_CONFIG branchJohan Hedberg1-12/+12
Checking for SC-only mode requirements when we get an encrypt change event shouldn't be limited to the BT_CONFIG state but done any time encryption changes. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-06-09Bluetooth: Fix encryption key size handling for LTKsJohan Hedberg1-1/+2
The encryption key size for LTKs is supposed to be applied only at the moment of encryption. When generating a Link Key (using LE SC) from the LTK the full non-shortened value should be used. This patch modifies the code to always keep the full value around and only apply the key size when passing the value to HCI.

2015-04-09Bluetooth: Read LE remote features during connection establishmentMarcel Holtmann1-2/+105
When establishing a Bluetooth LE connection, read the remote used features mask to determine which features are supported. This was not really needed with Bluetooth 4.0, but since Bluetooth 4.1 and also 4.2 have introduced new optional features, this becomes more important. This works the same as with BR/EDR where the connection enters the BT_CONFIG stage and hci_connect_cfm call is delayed until the remote features have been retrieved. Only after successfully receiving the remote features, the connection enters the BT_CONNECTED state.

2015-04-02Bluetooth: Convert local OOB data reading to use HCI requestJohan Hedberg1-11/+0
Now that there's a HCI request API available where the callback receives the resulting skb, we can convert the local OOB data reading to use this new API. This patch does the necessary update in mgmt.c (which also requires moving the callback higher up since it's now a static function) and removes the custom calls from hci_event.c that are no-longer necessary.

2015-04-02Bluetooth: Move hci_get_cmd_complete() to hci_event.cJohan Hedberg1-3/+54
To make the hci_req_run_skb() API consistent with hci_cmd_sync_ev() the callback should receive the cmd_complete parameters in the 'normal' case and the full HCI event if a special event was expected. This patch moves the hci_get_cmd_complete() function from hci_core.c to hci_event.c where it's used to strip the skb from the needed headers before passing it on to the callback.

2015-04-02Bluetooth: Remove unneeded recv_event variableJohan Hedberg1-12/+0
Now that the synchronous HCI requests use the new API and a new private variable the recv_evt member of hci_dev is no-longer needed. This patch removes it. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
