Johan Hedberg cecbb967b2 Bluetooth: Remove unused hdev->init_last_cmd
This variable is no longer needed (due to async HCI request support and
the conversion of hci_req_sync to use it), so it can be safely removed.

Johan Hedberg 42c6b129cd Bluetooth: Use async requests internally in hci_req_sync
This patch converts the hci_req_sync() procedure to internaly use the
asynchronous HCI requests.

The hci_req_sync mechanism relies on hci_req_complete() calls from
hci_event.c into hci_core.c whenever a HCI command completes. This is
very similar to what asynchronous requests do and makes the conversion
fairly straight forward by converting hci_req_complete into a request
complete callback. By this change hci_req_complete (renamed to
hci_req_sync_complete) becomes private to hci_core.c and all calls to it
can be removed from hci_event.c.

The commands in each hci_req_sync procedure are collected into their own
request by passing the hci_request pointer to the request callback
(instead of the hci_dev pointer). The one slight exception is the HCI
init request which has the special handling of HCI driver specific
initialization commands. These commands are run in their own request
prior to the "main" init request.

One other extra change that this patch must contain is the handling of
spontaneous HCI reset complete events that some controllers exhibit.
These were previously handled in the hci_req_complete function but the
right place for them now becomes the hci_req_cmd_complete function.

Johan Hedberg 9238f36a5a Bluetooth: Add request cmd_complete and cmd_status functions
This patch introduces functions to process the HCI request state when
receiving HCI Command Status or Command Complete events. Some HCI
commands, like Inquiry do not result in a Command complete event so
special handling is needed for them. Inquiry is a particularly important
one since it is the only forseeable "non-cmd_complete" command that will
make good use of the request functionality, and its completion is either
indicated by an Inquiry Complete event of a successful Command Complete
for HCI_Inquiry_Cancel.

Johan Hedberg 71c76a170e Bluetooth: Introduce new hci_req_add function
This function is analogous to hci_send_cmd() but instead of directly
queuing the command to hdev->cmd_q it adds it to the local queue of the
asynchronous HCI request being build (inside struct hci_request).

This is the main function used for building asynchronous requests and
there should be one or more calls to it between calls to hci_req_init
and hci_req_run.

Johan Hedberg 3119ae9599 Bluetooth: Add initial skeleton for asynchronous HCI requests
This patch adds the initial definitions and functions for asynchronous
HCI requests. Asynchronous requests are essentially a group of HCI
commands together with an optional completion callback. The request is
tracked through the already existing command queue by having the
necessary context information as part of the control buffer of each skb.

The only information needed in the skb control buffer is a flag for
indicating that the skb is the start of a request as well as the
optional complete callback that should be used when the request is
complete (this will be found in the last skb of the request).

Dean Jenkins 08c30aca9e Bluetooth: Remove RFCOMM session refcnt
Previous commits have improved the handling of the RFCOMM session
timer and the RFCOMM session pointers such that freed RFCOMM
session structures should no longer be erroneously accessed. The
RFCOMM session refcnt now has no purpose and will be deleted by
this commit.

Note that the RFCOMM session is now deleted as soon as the
RFCOMM control channel link is no longer required. This makes the
lifetime of the RFCOMM session deterministic and absolute.
Previously with the refcnt, there was uncertainty about when
the session structure would be deleted because the relative
refcnt prevented the session structure from being deleted at will.

It was noted that the refcnt could malfunction under very heavy
real-time processor loading in embedded SMP environments. This
could cause premature RFCOMM session deletion or double session
deletion that could result in kernel crashes. Removal of the
refcnt prevents this issue.

There are 4 connection / disconnection RFCOMM session scenarios:
host initiated control link ---> host disconnected control link
host initiated ctrl link ---> remote device disconnected ctrl link
remote device initiated ctrl link ---> host disconnected ctrl link
remote device initiated ctrl link ---> remote device disc'ed ctrl link

The control channel connection procedures are independent of the
disconnection procedures. Strangely, the RFCOMM session refcnt was
applying special treatment so erroneously combining connection and
disconnection events. This commit fixes this issue by removing
some session code that used the "initiator" member of the session
structure that was intended for use with the data channels.

Dean Jenkins 8ff52f7d04 Bluetooth: Return RFCOMM session ptrs to avoid freed session
Unfortunately, the design retains local copies of the s RFCOMM
session pointer in various code blocks and this invites the erroneous
access to a freed RFCOMM session structure.

Therefore, return the RFCOMM session pointer back up the call stack
to avoid accessing a freed RFCOMM session structure. When the RFCOMM
session is deleted, NULL is passed up the call stack.

If active DLCs exist when the rfcomm session is terminating,
avoid a memory leak of rfcomm_dlc structures by ensuring that
rfcomm_session_close() is used instead of rfcomm_session_del().

David Herrmann be9f97f045 Bluetooth: change bt_sock_unregister() to return void
There is no reason a caller ever wants to check the return type of this
call. _Iff_ a user successfully called bt_sock_register(), they're allowed
to call bt_sock_unregister().
All other calls in the kernel (device_del, device_unregister, kfree(), ..)
that are logically equivalent return void. Lets not make callers think
they have to check the return type of this call and instead simply return
void.

We guarantee that after bt_sock_unregister() is called, the socket type
_is_ unregistered. If that is not what the caller wants, they're using the
wrong function, anyway.

Johan Hedberg 83be8eca2e Bluetooth: Keep track of UUID type upon addition
The primary purpose of the UUIDs is to enable generation of EIR and AD
data. In these data formats the UUIDs are split into separate fields
based on whether they're 16, 32 or 128 bit UUIDs. To make the generation
of these data fields simpler this patch adds a type member to the
bt_uuid struct and assigns a value to it as soon as the UUID is added to
the kernel. This way the type doesn't need to be calculated each time
the UUID list is later iterated.

Mat Martineau 08333283a7 Bluetooth: Add new l2cap_chan struct members for high speed channels
An L2CAP channel using high speed continues to be associated with a
BR/EDR l2cap_conn, while also tracking an additional hci_conn
(representing a physical link on a high speed controller) and hci_chan
(representing a logical link).  There may only be one physical link
between two high speed controllers.  Each physical link may contain
several logical links, with each logical link representing a channel
with specific quality of service.

During a channel move, the destination channel id, current move state,
and role (initiator vs. responder) are tracked and used by the channel
move state machine.  The ident value associated with a move request
must also be stored in order to use it in later move responses.

The active channel is stored in local_amp_id.

Andrei Emeltchenko f706adfead Bluetooth: AMP: Get amp_mgr reference in HS hci_conn
When assigning amp_mgr in hci_conn (type AMP_LINK) get also reference.
In hci_conn_del those references would be put for both conn types
AMP_LINK and ACL_LINK associated with amp_mgr.

Gustavo Padovan 2dc4e5105f Bluetooth: Add chan->ops->defer()
When DEFER_SETUP is set defer() will trigger an authorization
request to the userspace.

l2cap_chan_no_defer() is meant to be used when one does not want to
support DEFER_SETUP (A2MP for example).
