2013-10-18Bluetooth: Expose auto_accept_delay debugfs only when SSP is supportedMarcel Holtmann1-31/+0
The auto_accept_delay debugfs entry is only valid for BR/EDR capable controllers that also support SSP. If SSP is not available or it is a LE-only single mode controller this value has no affect and so do not expose it. Since the value can be actually changed, switch the permissions to 0644 to clearly indicate that the value is indeed writeable.

2013-10-16Bluetooth: Expose inquiry_cache debugfs only on BR/EDR controllersMarcel Holtmann1-39/+0
The inquiry_cache debugfs entry is only valid for BR/EDR capable controllers. In case of single mode LE-only controllers that entry is not valid. Move the creating of the debugfs entries to the end of controller init and only create the inquiry_cache entry if BR/EDR is actually supported. At the same time this avoids creating any debugfs entries for AMP controllers since none of the entries are valid there.

2013-04-18Bluetooth: Track feature pages in a single tableJohan Hedberg1-8/+8
The local and remote features are organized by page number. Page 0 are the LMP features, page 1 the host features, and any pages beyond 1 features that future core specification versions may define. So far we've only had the first two pages and two separate variables has been convenient enough, however with the introduction of Core Specification Addendum 4 there are features defined on page 2. Instead of requiring the addition of a new variable each time a new page number is defined, this patch refactors the code to use a single table for the features. The patch needs to update both the hci_dev and hci_conn structures since there are macros that depend on the features being represented in the same way in both of them.

2013-04-17Bluetooth: introduce hci_conn ref-countingDavid Herrmann1-1/+0
We currently do not allow using hci_conn from outside of HCI-core. However, several other users could make great use of it. This includes HIDP, rfcomm and all other sub-protocols that rely on an active connection. Hence, we now introduce hci_conn ref-counting. We currently never call get_device(). put_device() is exclusively used in hci_conn_del_sysfs(). Hence, we currently never have a greater device-refcnt than 1. Therefore, it is safe to move the put_device() call from hci_conn_del_sysfs() to hci_conn_del() (it's the only caller). In fact, this even fixes a "use-after-free" bug as we access hci_conn after calling hci_conn_del_sysfs() in hci_conn_del(). From now on we can add references to hci_conn objects in other layers (like l2cap_sock, HIDP, rfcomm, ...) and grab a reference via hci_conn_get(). This does _not_ guarantee, that the connection is still alive. But, this isn't what we want. We can simply lock the hci_conn device and use "device_is_registered(hci_conn->dev)" to test that. However, this is hardly necessary as outside users should never rely on the HCI connection to be alive, anyway. Instead, they should solely rely on the device-object to be available. But if sub-devices want the hci_conn object as sysfs parent, they need to be notified when the connection drops. This will be introduced in later patches with l2cap_users.

2012-05-09Bluetooth: Remove redundant hdev->parent fieldDavid Herrmann1-1/+0
We initialize the "struct device" in hci_alloc_dev() for a long time now so we can access hdev->dev.parent directly. Hence, we can drop the temporary field hdev->parent which is used in no other place than hci_add_sysfs(). SET_HCIDEV_DEV() is never called after registering a device by the drivers so we do not overwrite internal device-state. Furthermore, hdev->dev is initialized to 0 by kzalloc() inside hci_alloc_dev() so the default behavior with dev.parent = NULL is kept.

2012-02-13Bluetooth: Introduce to_hci_connDavid Herrmann1-6/+4
This avoids using the dev_set/get_drvdata() functions to retrieve a pointer to our own structure. We can use simple pointer arithmetic here. The drvdata field is actually not needed by any other code-path but this makes the code more consistent with hci_dev.

2012-02-13Bluetooth: Introduce to_hci_dev()David Herrmann1-17/+16
We currently use dev_set_drvdata to keep a pointer to ourself. This doesn't make sense as we are the bus and not a driver. Therefore, introduce to_hci_dev() so we can get a struct hci_dev pointer from a struct device pointer. dev_set/get_drvdata() is reserved for drivers that provide a device and not for the bus using the device. The bus can use simple pointer arithmetic to retrieve its private data.

2011-10-14Bluetooth: Rename sysfs un/register to add/delDavid Herrmann1-2/+2
As we introduced hci_init_sysfs() we should also rename hci_register_sysfs() and hci_unregister_sysfs() to hci_add_sysfs() and hci_del_sysfs() like we do with hci_conn_add/del_sysfs().

2011-10-14Bluetooth: Fix hci core device initializationDavid Herrmann1-6/+12
We must not call device_del() if we didn't use device_add(). See module.c for comments on that. Therefore, we need to call device_initialize() when allocating the hci device and later device_add() instead of device_register(). This also fixes a bug when hci_register_dev() failed and we call hci_free_dev() without a valid core device. hci_free_dev() segfaults while calling put_device() on invalid memory. We already do this with hci_conn connections (hci_conn_init_sysfs()) so they do not need to be fixed. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Gustavo F.
