* Bluetooth: Fix potential NULL dereference in SMP channel setupMarcel Holtmann2015-03-181-3/+5
| | | | | | | | | | When the allocation of the L2CAP channel for the BR/EDR security manager fails, then the smp variable might be NULL. In that case do not try to free the non-existing crypto contexts Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Add workaround for broken OS X legacy SMP pairingJohan Hedberg2015-03-171-8/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OS X version 10.10.2 (and possibly older versions) doesn't support LE Secure Connections but incorrectly copies all authentication request bits from a Security Request to its Pairing Request. The result is that an SC capable initiator (such as BlueZ) will think OS X intends to do SC when in fact it's incapable of it: < ACL Data TX: Handle 3585 flags 0x00 dlen 6 SMP: Security Request (0x0b) len 1 Authentication requirement: Bonding, No MITM, SC, No Keypresses (0x09) > ACL Data RX: Handle 3585 flags 0x02 dlen 11 SMP: Pairing Request (0x01) len 6 IO capability: KeyboardDisplay (0x04) OOB data: Authentication data not present (0x00) Authentication requirement: Bonding, No MITM, SC, No Keypresses (0x09) Max encryption key size: 16 Initiator key distribution: EncKey (0x01) Responder key distribution: EncKey IdKey Sign (0x07) < ACL Data TX: Handle 3585 flags 0x00 dlen 11 SMP: Pairing Response (0x02) len 6 IO capability: NoInputNoOutput (0x03) OOB data: Authentication data not present (0x00) Authentication requirement: Bonding, No MITM, SC, No Keypresses (0x09) Max encryption key size: 16 Initiator key distribution: EncKey (0x01) Responder key distribution: EncKey Sign (0x05) The pairing eventually fails when we get an unexpected Pairing Confirm PDU instead of a Public Key PDU: > ACL Data RX: Handle 3585 flags 0x02 dlen 21 SMP: Pairing Confirm (0x03) len 16 Confim value: bcc3bed31b8f313a78ec3cce32685faf It is only at this point that we can speculate that the remote doesn't really support SC. This patch creates a workaround for the just-works model, however the MITM case is unsolvable because the OS X user has already been requested to enter a PIN which we're now expected to randomly generate and show the user (i.e. a chicken-and-egg problem).

* Bluetooth: Move generic mgmt command dispatcher to hci_sock.cJohan Hedberg2015-03-172-112/+115
| | | | | | | | | | | The mgmt.c file should be reserved purely for HCI_CHANNEL_CONTROL. The mgmt_control() function in it is already completely generic and has a single user in hci_sock.c. This patch moves the function there and renames it a bit more appropriately to hci_mgmt_cmd() (as it's a command dispatcher).

* Bluetooth: Add hdev_init callback for HCI channelsJohan Hedberg2015-03-171-2/+3
| | | | | | | | | | In order to make the mgmt command handling more generic we can't have a direct call to mgmt_init_hdev() from mgmt_control(). This patch adds a new callback to struct hci_mgmt_chan. And sets it to point to the mgmt_init_hdev() function for the HCI_CHANNEL_CONTROL instance.

* Bluetooth: Add generic mgmt helper APIJohan Hedberg2015-03-174-197/+265
| | | | | | | | | | There are several mgmt protocol features that will be needed by more than just the current HCI_CHANNEL_CONTROL. These include sending generic events as well as handling pending commands. This patch moves these functions out from mgmt.c to a new mgmt_util.c file.

* Bluetooth: Add channel parameter to mgmt_pending_find() APIJohan Hedberg2015-03-171-46/+62
| | | | | | | | | | | | | | To be able to have pending commands for different HCI channels we need to be able to distinguish for which channel a command was sent to. The channel information is already part of the socket data and can be fetched using the recently added hci_sock_get_channel() function. To not require all mgmt.c code to pass an extra channel parameter this patch also adds a helper pending_find() & pending_find_data() functions which act as a wrapper to the new mgmt_pending_find() & mgmt_pending_find_data() APIs.

* Bluetooth: Add simultaneous dual mode scanJakub Pawlowski2015-03-173-10/+70
| | | | | | | | | | | | When doing scan through mgmt api, some controllers can do both le and classic scan at same time. They can be distinguished by HCI_QUIRK_SIMULTANEOUS_DISCOVERY set. This patch enables them to use this feature when doing dual mode scan. Instead of doing le, then classic scan, both scans are run at once.

| | | | | | | | | | When a different user requests a new set of local out-of-band data, then inform all previous users that the data has been updated. To limit the scope of users, the updates are limited to previous users. If a user has never requested out-of-band data, it will also not see the update.

| | | | | | | | | | When we receive the remote public key, if we have remote OOB data there's no point in sending our public key to the remote if the OOB data doesn't match.

* Bluetooth: Track local vs remote OOB data availabilityJohan Hedberg2015-03-161-4/+6
| | | | | | | | | | There are several decisions in the SMP logic that depend not only on whether we're doing SMP or not, but also whether local and/or remote OOB data is present.

* Bluetooth: Create SMP device structure for local crypto contextMarcel Holtmann2015-03-161-16/+31
| | | | | | | | | | | | Every Bluetooth Low Energy controller requires a local crypto context to handle the resolvable private addresses. At the moment this is just a single crypto context, but for out-of-band data generation it will require an additional. To facility this, create a struct smp_dev that will hold all the extra information. This patch is just the refactoring in preparation for future changes.

* Bluetooth: Remove unneeded HCI_CONN_REMOTE_OOB connection flagMarcel Holtmann2015-03-161-2/+0
| | | | | | | | | | | | | | The HCI_CONN_REMOTE_OOB connection flag is used to indicate if the pairing initiator has provided out-of-band data. However since that value is no longer used in any decision making, just remove it. It is actually unclear what purpose the OOB data present field from the HCI IO Capability Response event serves in the first place. If either side provided out-of-band data, then that data will be used for pairing. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Fix BR/EDR out-of-band pairing with only initiator dataMarcel Holtmann2015-03-161-29/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When only the pairing initiator is providing out-of-band data, then the receiver side was ignoring the data. For some reason the code was checking if the initiator has received out-of-band data and only then also provide the required inidication that the acceptor actually has the needed data available. For BR/EDR out-of-band pairing it is enough if one side has received out-of-band data. There are no extra checks needed here to make this work smoothly. The only thing that is needed is to tell the controller if data is present (and if it is P-192 or P-256 or both) and then let the controller actually figure out the rest. This means the check for outgoing connection or if the initiator has indicated data are completely pointless and are in fact actually causing harm. The check in question is this one: if (conn->out || test_bit(HCI_CONN_REMOTE_OOB, &conn->flags)) { After just taking the conditional check out and always executing the code for determining the type of out-of-band data, the pairing works flawlessly and prodcudes authenticated link keys. The patch itself looks more complicated due to the reformatting of the indentation, but it essentially just a two-line change.
