Bluetooth: introduce hci_conn ref-counting
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.

/*
|
|
|
|
* hci_conn_get() and hci_conn_put() are used to control the life-time of an
|
|
|
|
* "hci_conn" object. They do not guarantee that the hci_conn object is running,
|
|
|
|
* working or anything else. They just guarantee that the object is available
|
|
|
|
* and can be dereferenced. So you can use its locks, local variables and any
|
|
|
|
* other constant data.
|
|
|
|
* Before accessing runtime data, you _must_ lock the object and then check that
|
|
|
|
* it is still running. As soon as you release the locks, the connection might
|
|
|
|
* get dropped, though.
|
|
|
|
*
|
|
|
|
* On the other hand, hci_conn_hold() and hci_conn_drop() are used to control
|
|
|
|
* how long the underlying connection is held. So every channel that runs on the
|
|
|
|
* hci_conn object calls this to prevent the connection from disappearing. As
|
|
|
|
* long as you hold a device, you must also guarantee that you have a valid
|
|
|
|
* reference to the device via hci_conn_get() (or the initial reference from
|
|
|
|
* hci_conn_add()).
|
|
|
|
* The hold()/drop() ref-count is known to drop below 0 sometimes, which doesn't
|
|
|
|
* break because nobody cares for that. But this means, we cannot use
|
|
|
|
* _get()/_drop() in it, but require the caller to have a valid ref (FIXME).
