There is no external user of the SCO timeout constants and thus move them into net/bluetooth/sco.c where they are actuallu used. In addition just remove SCO_CONN_IDLE_TIMEOUT since it is unused. Signed-off-by:

The SCO_DEFAULT_FLUSH_TO constant has been defined, but it is not used anywhere and so just remove it. Signed-off-by:

The internals of the HCI request framework should not be leaking to its users. Move them all into net/bluetooth/hci_core.c and provide a simple hci_req_pending helper function for the one user outside the framework. Signed-off-by:

The hci_sec_filter socket filter details do not change. They are fixed and with that they can also be delcared as const. Signed-off-by:

There is only single location using struct hci_sec_filter and with that there is no point in putting this declaration into a global header file. So move it right next to its user and make the code a lot more simpler. Signed-off-by:

All the HCI sockets and ioctl based definitions have been in a global header file that also includes all the HCI protocol structures. To make this a bit cleaner, move them into its own file. This also adjusts fs/compat_ioctl.c to only include this new file and not all the protocol structures that are not needed. Signed-off-by:

When the controller is brought up using legacy ioctl, the setting of the HCI_PAIRABLE flag should happen then. Previously it was set during enumeration and when retrieving device information. This change also will not set the HCI_PAIRABLE flag when the controller is used with the HCI User Channel operation. Signed-off-by:

During the initial setup phase, the controller is powered on and will be powered off again if it is not used within the auto-off timeout. Userspace using ioctl does not know about the difference between the initial setup phase and a controller being present. It is a bad idea to keep the controller powered by just looking at the device list or device information. Instead just tell userspace that the controller is still down. Signed-off-by:

The Set Connectable/Discoverable mgmt handlers use a hci_request with a proper callback to handle the HCI command sending. It makes therefore little sense to have this extra function to be called from hci_event.c for command failures. Signed-off-by:

Since the HCISETSCAN ioctl is the only non-mgmt user we care about for setting the right discoverable state we can simply do the necessary updates in the ioctl handler function instead. This then allows the removal of the mgmt_discoverable function and should simplify that state handling considerably. Signed-off-by:
-
Johan Hedberg authored
With subsequent patches we'll also need to update the discoverable state. As the code grows bigger it's better to move this out from the switch statement into its own function. Signed-off-by:
-
Johan Hedberg authored
The mgmt_connectable function has been used to ensure that the right actions to HCI_CONNECTABLE are taken when the HCI_Write_Scan_Enable command is triggered by something else than mgmt. The only other user that we really care about is the HCISETSCAN ioctl code, so we can actually more simply perform the needed changes there instead. Signed-off-by:

The code for updating the HCI_CONNECTABLE flag was incorrectly using test_and_set_bit instead of test_and_clear_bit when HCI_CONNECTABLE is to be cleared. Signed-off-by:

If the remote device tries to initiate bonding with us and we don't have HCI_PAIRABLE set we should just flat out reject the request. This brings SMP in line with how the flag is used for BR/EDR SSP. Signed-off-by:

When we change the connectable state and have advertising enabled we should update the advertising parameters no matter what. The code was incorrectly only updating them if advertising was not already active. This patch fixes the issue. Signed-off-by:

When the SMP context is created all flags default to zero. To determine that we are the initiators it's therefore best to simply change the flag value when we know we're sending the first SMP PDU. Clearing the flag when receiving a Pairing Request is not correct since the request may be a response to a previous Security Request from us (for which we would already have correctly set the flag). Same goes for receiving a Security Request which may be coming after us already starting pairing by sending a Pairing Request. Signed-off-by:

Whether we bond or not should not have any impact on the user interaction model. This patch removes an incorrect fall-back from JUST_CFM to JUST_WORKS in case we're not bonding. Signed-off-by:
-
Johan Hedberg authored
For incoming requests we want to let the user know that pairing is happening since otherwise there could be access to MEDIUM security services without any user interaction at all. Therefore, set the selected method to JUST_CFM instead of JUST_WORKS and let it be converted back to JUST_WORKS later if we are the initators. Signed-off-by:

When the white list is in use the code would not update the HCI_CONNECTABLE flag if it gets changed through the ioctl code (e.g. hciconfig hci0 pscan). Since the flag is important for properly accepting incoming connections add code to fix it up if necessary and emit a New Settings mgmt event. Signed-off-by:

This patch adds support for looking up entries in the white list when HCI_CONNECTABLE is not set. The logic is fairly simple: if we're connectable check the black list, if we're not connectable check the white list. Signed-off-by:

Page scan should be enabled either if the connectable setting is set or if there are any entries in the BR/EDR white list. This patch implements such behavior by updating the two places that were making decisions on whether to enable page scan or not. Signed-off-by:

The conditions for accepting an incoming connections are already non-trivial and will become more so once a white list is added. This patch breaks up the checks for when to reject the request by creating a helper function for it. Signed-off-by:

Since page scan might be enabled by Add Device we should not implicitly set connectable whenever something else than Set Connectable changes it. This patch makes sure that we don't set HCI_CONNECTABLE for these cases if there are any entries in the white list. Signed-off-by:

Johan Hedberg authored
When we're removing the last item in the white list or adding the first one to it and HCI_CONNECTABLE is not set we need to update the current page scan. This patch adds a simple helper function for the purpose and calls it from the respective mgmt command handlers. Signed-off-by:

This patch extends the Add/Remove device commands by letting user space pass BR/EDR addresses to them. The resulting entries get stored in a new hdev->whitelist list. The idea is that we can now selectively accept connections from devices in the list even though HCI_CONNECTABLE is not set (the actual implementation of this is coming in a subsequent patch).

We already have several lists with struct bdaddr_list entries, and there will be more in the future. Since the operations for adding, removing, looking up and clearing entries in these lists are exactly the same it doesn't make sense to define new functions for every single list. This patch unifies the functions by passing the list_head to them instead of a hci_dev pointer. Signed-off-by:

The Authenticated Payload Timeout Expired event is valid for controllers with BR/EDR Secure Connections support, but also for LE only controllers supporting LE Ping feature. When either of them is available enable this event. Previous it was not enabled when the controller was only supporting LE operation. Signed-off-by:

All LE controllers always implicitly stop advertising when establishing connections. Therefore, be sure to clear the flag in the event handler for new LE connections. Signed-off-by:

If the connectable state change doesn't require any special HCI commands the set_connectable_update_settings() function is used instead of the set_connectable_complete() function. We must therefore make sure to call hci_update_background_scan() there as well. This code path is used also when we're powered off, but that's fine since hci_update_background_scan() has the necessary checks for it. Signed-off-by:

The connectable and discoverable mgmt settings are supported both for LE and BR/EDR controllers so they do not belong behind a lmp_bredr_capable() condition. This patch fixes the issue in get_supported_settings(). Signed-off-by:

If any of the HCI commands from the hci_stop_discovery function were successfully sent we need to set the discovery state to STOPPING. The Stop Discovery code was already handling this, but the code in clean_up_hci_state was not. This patch updates the hci_stop_discovery to return a bool to indicate whether it queued any commands and the clean_up_hci_state() function respectively to look at the return value and call hci_discovery_set_state() if necessary.

There are many different places that can disable LE scanning but we only want to re-enable advertising in hci_cc_le_set_scan_enable() for a very specific use case, which is when the active scanning part of Start Discovery is complete. Because of this, fix the discovery state check to test for the exact state. Signed-off-by:

Many controllers allow simultaneous active scanning and advertising (e.g. Intel and Broadcom) but some do not (e.g. CSR). It's therefore safest to implement mutual exclusion of these states in the kernel. This patch ensures that the two states are never entered simultaneously. Extra precaution needs to be taken for outgoing connection attempts in slave role (i.e. through directed advertising) in which case the operation that came first has precedence and the one that comes after gets a rejection.
