Bluetooth: Expire RPA if encryption fails
If encryption fails and we're using an RPA it may be because of a
conflict with another device. To avoid repeated failures the safest
action is to simply mark the RPA as expired so that a new one gets
generated as soon as the connection drops.

Bluetooth: Fix hci_conn reference counting for auto-connections
Recently the LE passive scanning and auto-connections feature was
introduced. It uses the hci_connect_le() API which returns a hci_conn
along with a reference count to that object. All previous users would
tie this returned reference to some existing object, such as an L2CAP
channel, and there'd be no leaked references this way. For
auto-connections however the reference was returned but not stored
anywhere, leaving established connections with one higher reference
count than they should have.
Instead of playing special tricks with hci_conn_hold/drop this patch
associates the returned reference from hci_connect_le() with the object
that in practice does own this reference, i.e. the hci_conn_params
struct that caused us to initiate a connection in the first place. Once
the connection is established or fails to establish this reference is
removed appropriately.
One extra thing needed is to call hci_pend_le_actions_clear() before
calling hci_conn_hash_flush() so that the reference is cleared before
the hci_conn objects are fully removed.

Bluetooth: Fix issue with ADV_IND reports and auto-connection handling
When adding remote devices to the kernel using the Add Device management
command, these devices are explicitly allowed to connect. This kind of
incoming connections are possible even when the controller itself is
not connectable.
For BR/EDR this distinction is pretty simple since there is only one
type of incoming connections. With LE this is not that simple anymore
since there are ADV_IND and ADV_DIRECT_IND advertising events.
The ADV_DIRECT_IND advertising events are send for incoming (slave
initiated) connections only. And this is the only thing the kernel
should allow when adding devices using action 0x01. This meaning
of incoming connections is coming from BR/EDR and needs to be
mapped to LE the same way.
Supporting the auto-connection of devices using ADV_IND advertising
events is an important feature as well. However it does not map to
incoming connections. So introduce a new action 0x02 that allows
the kernel to connect to devices using ADV_DIRECT_IND and in addition
ADV_IND advertising reports.
This difference is represented by the new HCI_AUTO_CONN_DIRECT value
for only connecting to ADV_DIRECT_IND. For connection to ADV_IND and
ADV_DIRECT_IND the old value HCI_AUTO_CONN_ALWAYS is used.

Bluetooth: Fix tracking local SSP authentication requirement
When we need to make the decision whether to perform just-works or real
user confirmation we need to know the exact local authentication
requirement that was passed to the controller. So far conn->auth_type
(the local requirement) wasn't in one case updated appropriately in fear
of the user confirmation being rejected later.
The real problem however was not really that conn->auth_type couldn't
represent the true value but that we were checking the local MITM
requirement in an incorrect way. It's perfectly fine to let auth_type
follow what we tell the controller since we're still tracking the target
security level with conn->pending_sec_level.
This patch updates the check for local MITM requirement in the
hci_user_confirm_request_evt function to use the locally requested
security level and ensures that auth_type always represents what we tell
the controller. All other code in hci_user_confirm_request_evt still
uses the auth_type instead of pending_sec_level for determining whether
to do just-works or not, since that's the only value that's in sync with
what the remote device knows.

Bluetooth: Add flag to track the real advertising state
Having a single HCI_ADVERTISING flag is problematic since it tries to
track both the real advertising state and the corresponding mgmt
setting. To make the logic simpler and more reliable add a new flag that
only tracks the actual advertising state that has been written to the
controller.

Bluetooth: Pass desired connection role to hci_connect_le()
If we have both LE scanning and advertising simultaneously enabled we
need a way to tell hci_connect_le() in which role to initiate a
connection. This patch adds a new parameter to the function to give it
the necessary information. For auto-connect and mgmt_pair_device we
always use master role, whereas for L2CAP users (in practice sockets) we
use slave role whenever HCI_ADVERTISING is set and master role
otherwise.

Bluetooth: Add clarifying comment for conn->auth_type
When responding to an IO capability request when we're the initiators of

Since the conn->auth_type variable is treated as an "absolute"
requirement instead of a hint of what's needed later in the user
confirmation request handler it's important that it doesn't have the
MITM bit set if there's any chance that the remote device doesn't have

refresh complete event with the intent of fixing some LE/SMP cases.
However, this event is shared with BR/EDR and there we actually want to
act only on the auth_complete event (which comes after the key refresh).
If we do not do this we may trigger an L2CAP Connect Request too early

Bluetooth: Request MITM Protection when initiator
The GAP Specification gives the flexibility to decide whether MITM
Protection is requested or not (Bluetooth Core Specification v4.0
Volume 3, part C, section 6.5.3) when replying to an
HCI_EV_IO_CAPA_REQUEST event.
The recommendation is *not* to set this flag "unless the security
policy of an available local service requires MITM Protection"
(regardless of the bonding type). However, the kernel doesn't
necessarily have this information and therefore the safest choice is
to always use MITM Protection, also for General Bonding.
This patch changes the behavior for the General Bonding initiator
role, always requesting MITM Protection even if no high security level
is used. Depending on the remote capabilities, the protection might
not be actually used, and we will accept this locally unless of course
a high security level was originally required.
Note that this was already done for Dedicated Bonding. No-Bonding is
left unmodified because MITM Protection is normally not desired in
these cases.

Bluetooth: Merge ADV_IND/ADV_SCAN_IND and SCAN_RSP together
To avoid too many events being sent to user space and to help parsing of
all available remote device data it makes sense for us to wait for the
scan response and send a single merged Device Found event to user space.
This patch adds a few new variables to hci_dev to track the last
received ADV_IND/ADV_SCAN_IND, i.e. those which will cause a SCAN_REQ to
be send in the case of active scanning. When the SCAN_RSP is received
the pending data is passed together with the SCAN_RSP to the
mgmt_device_found function which takes care of merging them into a
single Device Found event.
We also need a bit of extra logic to handle situations where we don't
receive a SCAN_RSP after caching some data. In such a scenario we simply
have to send out the pending data as it is and then operate on the new
report as if there was no pending data.
We also need to send out any pending data when scanning stops as
well as ensure that the storage is empty at the start of a new active
scanning session. These both cases are covered by the update to the
hci_cc_le_set_scan_enable function in this patch.

Bluetooth: Fix removing Long Term Key
This patch fixes authentication failure on LE link re-connection when
BlueZ acts as slave (peripheral). LTK is removed from the internal list
after its first use causing PIN or Key missing reply when re-connecting
the link. The LE Long Term Key Request event indicates that the master
is attempting to encrypt or re-encrypt the link.
Pre-condition: BlueZ host paired and running as slave.
How to reproduce(master):
1) Establish an ACL LE encrypted link
2) Disconnect the link
3) Try to re-establish the ACL LE encrypted link (fails)

Bluetooth: Remove unnecessary stop_scan_complete function
The stop_scan_complete function was used as an intermediate step before
doing the actual connection creation. Since we're using hci_request
there's no reason to have this extra function around, i.e. we can simply
put both HCI commands into the same request.
The single task that the intermediate function had, i.e. indicating
discovery as stopped is now taken care of by a new
HCI_LE_SCAN_INTERRUPTED flag which allows us to do the discovery state
update when the stop scan command completes.

Bluetooth: Fix trying to disable scanning twice
The discovery process has a timer for disabling scanning, however
scanning might be disabled through other means too like the auto-connect
process. We should therefore ensure that the timer is never active
after sending a HCI command to disable scanning.
There was some existing code in stop_scan_complete trying to avoid the
timer when a connect request interrupts a discovery procedure, but the
other way around was not covered. This patch covers both scenarios by
canceling the timer as soon as we get a successful command complete for
the disabling HCI command.

Bluetooth: Add timeout for LE connection attempts
LE connection attempts do not have a controller side timeout in the same
way as BR/EDR has (in form of the page timeout). Since we always do
scanning before initiating connections the attempts are always expected
to succeed in some reasonable time.
This patch adds a timer which forces a cancellation of the connection
attempt within 20 seconds if it has not been successful by then. This
way we e.g. ensure that mgmt_pair_device times out eventually and gives
an error response.

Bluetooth: Introduce LE auto connect options
This patch introduces the LE auto connection options: HCI_AUTO_CONN_
ALWAYS and HCI_AUTO_CONN_LINK_LOSS. Their working mechanism are
described as follows:
The HCI_AUTO_CONN_ALWAYS option configures the kernel to always re-
establish the connection, no matter the reason the connection was
terminated. This feature is required by some LE profiles such as
HID over GATT, Health Thermometer and Blood Pressure. These profiles
require the host autonomously connect to the device as soon as it
enters in connectable mode (start advertising) so the device is able
to delivery notifications or indications.
The BT_AUTO_CONN_LINK_LOSS option configures the kernel to re-
establish the connection in case the connection was terminated due
to a link loss. This feature is required by the majority of LE
profiles such as Proximity, Find Me, Cycling Speed and Cadence and
Time.

Bluetooth: Introduce LE auto connection infrastructure
This patch introduces the LE auto connection infrastructure which
will be used to implement the LE auto connection options.
In summary, the auto connection mechanism works as follows: Once the
first pending LE connection is created, the background scanning is
started. When the target device is found in range, the kernel
autonomously starts the connection attempt. If connection is
established successfully, that pending LE connection is deleted and
the background is stopped.
To achieve that, this patch introduces the hci_update_background_scan()
which controls the background scanning state. This function starts or
stops the background scanning based on the hdev->pend_le_conns list. If
there is no pending LE connection, the background scanning is stopped.
Otherwise, we start the background scanning.
Then, every time a pending LE connection is added we call hci_update_
background_scan() so the background scanning is started (in case it is
not already running). Likewise, every time a pending LE connection is
deleted we call hci_update_background_scan() so the background scanning
is stopped (in case this was the last pending LE connection) or it is
started again (in case we have more pending LE connections). Finally,
we also call hci_update_background_scan() in hci_le_conn_failed() so
the background scan is restarted in case the connection establishment
fails. This way the background scanning keeps running until all pending
LE connection are established.
At this point, resolvable addresses are not support by this
infrastructure. The proper support is added in upcoming patches.

The change for the management interface is transparent and no change
is required for existing userspace. The Secure Connections feature
needs to be manually enabled. When it is disabled, then userspace
only gets the P-192 returned and with Secure Connections enabled,
userspace gets P-192 and P-256 in an extended structure.
It is also acceptable to just ignore the P-256 data since it is not
required to support them. The pairing with out-of-band credentials
will still succeed. However then of course no Secure Connection will
b established.

Bluetooth: Add management command for enabling Secure Connections
The support for Secure Connections need to be explicitly enabled by
userspace. This is required since only userspace that can handle the
new link key types should enable support for Secure Connections.
This command handling is similar to how Secure Simple Pairing enabling
is done. It also tracks the case when Secure Connections support is
enabled via raw HCI commands. This makes sure that the host features
page is updated as well.

Bluetooth: Fix outgoing authentication requirement check
The check for HIGH security level dates back to pre-mgmt times when a
raw L2CAP socket with HIGH security level was used to trigger dedicated
bonding. For legacy pairing checking for the security level was the only
way to catch the need to authenticate in all scenarios. With mgmt
however, the pair_device command does not use HIGH security but MEDIUM
security. Therefore, the existing code would never trigger
authentication for a non-SSP connection without an MITM requirement
(e.g. if user space provided a NoInputNoOutput IO capability). In such a
scenario the mgmt_pair_device command would return success without
actually triggering any kind of pairing.
This patch updates the authentication requirement check to also consider
MEDIUM security level, and thereby ensures that mgmt_pair_device will
always trigger authentication.

Bluetooth: Refactor hci_disconn_complete_evt
hci_disconn_complete_evt() logic is more complicated than what it
should be, making it hard to follow and add new features.
So this patch does some code refactoring by handling the error cases
in the beginning of the function and by moving the main flow into the
first level of function scope. No change is done in the event handling
logic itself.
Besides organizing this messy code, this patch makes easier to add

According to b644ba336 (patch that introduced HCI_CONN_MGMT_CONNECTED
flag), the HCI_CONN_MGMT_CONNECTED flag tracks when mgmt has been
notified about the connection.
That being said, there is no point in calling mgmt_disconnect_failed()
conditionally based on this flag. mgmt_disconnect_failed() removes
pending MGMT_OP_DISCONNECT commands, it doesn't matter if that
connection was notified or not.
Moreover, if the Disconnection Complete event has status then we have
nothing else to do but call mgmt_disconnect_failed() and return.

Therefore we should set conn->pending_sec_level instead of conn->

properly updated in hci_encrypt_change_evt.

Bluetooth: Track feature pages in a single table
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

Bluetooth: Fix incorrect SSP mode bit for non SSP devices
Some faulty non SSP devices send extended inquiry response
during device discovery which is a violation of 2.1 specification.
So for these devices we set SSP bit during acl connection
initiation thinking that it is an SSP device. But for these
devices, in remote host features event SSP supported bit
will be off. But we are not clearing the SSP bit in that case
and eventually SSP bit in conn flag will be incorrectly set for
these devices.
The software which has caused this issue is MecApp
http://www.mecel.se/products/bluetooth/downloads/MecApp_download
This patch does a workaround by clearing the SSP bit if it is
not supported in remote host features event

Bluetooth: remove unneeded hci_conn_hold/put_device()
hci_conn_hold/put_device() is used to control when hci_conn->dev is no
longer needed and can be deleted from the system. Lets first look how they
are currently used throughout the code (excluding HIDP!).
All code that uses hci_conn_hold_device() looks like this:
...
hci_conn_hold_device();
hci_conn_add_sysfs();
...
On the other side, hci_conn_put_device() is exclusively used in
hci_conn_del().
So, considering that hci_conn_del() must not be called twice (which would
fail horribly), we know that hci_conn_put_device() is only called _once_
(which is in hci_conn_del()).
On the other hand, hci_conn_add_sysfs() must not be called twice, either
(it would call device_add twice, which breaks the device, see
drivers/base/core.c). So we know that hci_conn_hold_device() is also
called only once (it's only called directly before hci_conn_add_sysfs()).
So hold and put are known to be called only once. That means we can safely
remove them and directly call hci_conn_del_sysfs() in hci_conn_del().
But there is one issue left: HIDP also uses hci_conn_hold/put_device().
However, this case can be ignored and simply removed as it is totally
broken. The issue is, the only thing HIDP delays with
hci_conn_hold_device() is the removal of the hci_conn->dev from sysfs.
But, the hci_conn device has no mechanism to get notified when its own
parent (hci_dev) gets removed from sysfs. hci_dev_hold/put() does _not_
control when it is removed but only when the device object is created
and destroyed.
And hci_dev calls hci_conn_flush_*() when it removes itself from sysfs,
which itself causes hci_conn_del() to be called, but it does _not_ cause
hci_conn_del_sysfs() to be called, which is wrong.
Hence, we fix it to call hci_conn_del_sysfs() in hci_conn_del(). This
guarantees that a hci_conn object is removed from sysfs _before_ its
parent hci_dev is removed.
The changes to HIDP look scary, wrong and broken. However, if you look at
the HIDP session management, you will notice they're already broken in the
exact _same_ way (ever tried "unplugging" HIDP devices? Breaks _all_ the
time).
So this patch only makes HIDP look _scary_ and _obviously broken_. It does
not break HIDP itself, it already is!
See later patches in this series which fix HIDP to use proper
session-management.

Bluetooth: rename hci_conn_put to hci_conn_drop
We use _get() and _put() for device ref-counting in the kernel. However,
hci_conn_put() is _not_ used for ref-counting, hence, rename it to
hci_conn_drop() so we can later fix ref-counting and introduce
hci_conn_put().
hci_conn_hold() and hci_conn_put() are currently used to manage how long a
connection should be held alive. When the last user drops the connection,
we spawn a delayed work that performs the disconnect. Obviously, this has
nothing to do with ref-counting for the _object_ but rather for the
keep-alive of the connection.
But we really _need_ proper ref-counting for the _object_ to allow
connection-users like rfcomm-tty, HIDP or others.

Bluetooth: Add support for custom event terminated commands
This patch adds support for having commands within HCI requests that do
not result in a command complete but some other event. This is at least
needed for some vendor specific commands to be issued in the
hdev->setup() procecure, but might also be useful for other commands.
The way that the support is implemented is by extending the skb control
buffer to have a field to indicate that the command is expected to
terminate with a special event. After sending the command each received
event can then be compared against this field through hdev->sent_cmd.

Bluetooth: Fix HCI request framework
Some HCI commands don't send a Command Complete Event once the HCI
command has completed so they require some special handling from the
HCI request framework. These HCI commands, however, send a Command
Status Event to indicate that the command has been received, and
that the controller is currently performing the task for the command.
So, in order to properly handle those HCI commands, the HCI request
framework should consider the HCI command has completed once the
Command Status Event is received.
This way, we fix some issues regarding the Inquiry command support,
as well as add support for all those HCI commands which would require
some special handling from the HCI request framework.

Bluetooth: Handle AD updating through an async request
For proper control of the AD update and the related HCI commands it's
best to run the AD update through an async request instead of a
standalone HCI command. This patch changes the hci_update_ad() function
to take a request pointer and updates its users appropriately. E.g. the
function is no longer called after the init sequence but during stage 3
of the init sequence.
The TX power is read during the init sequence, so we don't need an
explicit update whenever it is read and the AD update based on the local

Bluetooth: Fix endianness handling of cmd_status/complete opcodes
The opcode in cmd_complete and cmd_status events is 16 bits, so we
should only be comparing it after having converted it to the host
endianness. There's already an opcode variable in both functions which
is in host endiannes so the right fix is to just start using it instead
of ev->opcode.

Bluetooth: Remove empty HCI event handlers
With the removal of hci_req_complete() several HCI event handlers have
essentially become empty and can be removed. The only potential benefit
of these could have been logging, but the hci_event, hci_cmd_complete
and hci_cmd_status already provide a log for events which they do not
have an explicit handler for.

Johan Hedberg <johan.hedberg@intel.com> |
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.

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.

Bluetooth: Split HCI init sequence into three stages
Having conditional command sending during a request has always been
problematic and caused hacks like the hdev->init_last_cmd variable. This
patch removes these conditionals and instead splits the init sequence
into three stages, each with its own __hci_req_sync() call.
This also paves the way to the upcoming asynchronous request support
swhich will also benefit by having a simpler implementation if it
doesn't need to cater for requests that change on the fly.

Bluetooth: mgmt: Add device disconnect reason
MGMT_EV_DEVICE_DISCONNECTED will now expose the disconnection reason to
userland, distinguishing four possible values:
0x00 Reason not known or unspecified
0x01 Connection timeout
0x02 Connection terminated by local host
0x03 Connection terminated by remote host
Note that the local/remote distinction just determines which side
terminated the low-level connection, regardless of the disconnection of
the higher-level profiles.
This can sometimes be misleading and thus must be used with care. For
example, some hardware combinations would report a locally initiated
disconnection even if the user turned Bluetooth off in the remote side.

Bluetooth: Fix legacy pairing with some devices
Some devices e.g. some Android based phones don't do SDP search before
pairing and cancel legacy pairing when ACL is disconnected.
PIN Code Request event which changes ACL timeout to HCI_PAIRING_TIMEOUT
is only received after remote user entered PIN.
In that case no L2CAP is connected so default HCI_DISCONN_TIMEOUT
(2 seconds) is being used to timeout ACL connection. This results in
problems with legacy pairing as remote user has only few seconds to
enter PIN before ACL is disconnected.
Increase disconnect timeout for incomming connection to
HCI_PAIRING_TIMEOUT if SSP is disabled and no linkey exists.
To avoid keeping ACL alive for too long after SDP search set ACL
timeout back to HCI_DISCONN_TIMEOUT when L2CAP is connected.

Bluetooth: notify userspace of security level change
It fixes L2CAP socket based security level elevation during a
connection. The HID profile needs this (for keyboards) and it is the only
way to achieve the security level elevation when using the management
interface to talk to the kernel (hence the management enabling patch
being the one that exposes this issue).
It enables the userspace a security level change when the socket is
already connected and create a way to notify the socket the result of the
request. At the moment of the request the socket is made non writable, if
the request fails the connections closes, otherwise the socket is made
writable again, POLL_OUT is emmited.

Bluetooth: mgmt: Fix updating EIR when updating the name
Whenever we update the local device name the EIR data also needs to be
updated to reflect this. The update_eir() function in mgmt.c depends on
hdev->dev_name to be up to date so the patch also makes sure that the
mgmt function is called from hci_event.c after the update has happened.

Bluetooth: Merge INQUIRY and LE_SCAN discovery states
This patch merges DISCOVERY_INQUIRY and DISCOVERY_LE_SCAN states
into a new state called DISCOVERY_FINDING.
From the discovery perspective, we are pretty much worried about
to know just if we are finding devices than what exactly phase of
"finding devices" (inquiry or LE scan) we are currently running.
Besides, to know if the controller is performing inquiry or LE scan
we should check HCI_INQUIRY or HCI_LE_SCAN bits in hdev flags.
Moreover, merging this two states will simplify the discovery state
machine and will keep interleaved discovery implementation simpler.

Bluetooth: Fix adv_work delay
This patch fixes the adv_work delay. It should be set to ADV_
CLEAR_TIMEOUT instead of (jiffies + ADV_CLEAR_TIMEOUT) since
queue_delayed_work() receives the number of jiffies to wait
before queueing. It also removes the unnecessary cancel_delayed_
work_sync() call in case LE scan has been disabled.

Bluetooth: Add dev_flags to struct hci_dev
This patch adds the dev_flags field to struct hci_dev. This new
flags variable should be used to define flags related to BR/EDR
and/or LE controller itself. It should be used to define flags
which represents states from the controller. The dev_flags is
cleared in case the controller sends a Reset Command Complete
Event to the host.
Also, this patch adds the HCI_LE_SCAN flag which was created to
track if the controller is performing LE scan or not. The flag
is set/cleared when the controller starts/stops scanning.
This is an initial effort to stop using hdev->flags to define
internal flags since it is exported to userspace by an ioctl.

Bluetooth: Pass full hci_dev struct to mgmt callbacks
The current global pending command list in mgmt.c is racy. Possibly the
simplest way to fix it is to have per-hci dev lists instead of a global
one (all commands that need a pending struct are hci_dev specific).
This way the list can be protected using the already existing per-hci
dev lock. To enable this refactoring the first thing that needs to be
done is to ensure that the mgmt functions have access to the hci_dev
struct (instead of just the dev id).

Andre Guedes <andre.guedes@openbossa.org> |
Bluetooth: Periodic Inquiry and Discovery
By using periodic inquiry command we're not able to detect correctly
when the controller has started inquiry.
Today we have this workaround in inquiry result event handler
to set the HCI_INQUIRY flag when it sees the first inquiry result
event. This workaround isn't enough because the device may be
performing an inquiry but the HCI_INQUIRY flag is not set. For
instance, if there is no device in range, no inquiry result event
is generated, consequently, the HCI_INQUIRY flags isn't set when
it should so.
We rely on HCI_INQUIRY flag to implement the discovery procedure
properly. So, as we aren't able to clear/set the HCI_INQUIRY flag
in a reliable manner, periodic inquiry events shouldn't change
the HCI_INQUIRY flag.
Thus, due to that issue and in order to keep compatibility with
userspace, periodic inquiry events shouldn't send mgmt discovering
events.
In future, we might track if periodic inquiry is enabled or not.
By tracking this state we'll be able to do some improvements in
Discovery such as failing MGMT_OP_START_DISCOVERY command in case
periodic inquiry is on. We can also send no mgmt_device_found
event if periodic inquiry is on.

Bluetooth: Add support for storing the key size
In some cases it will be useful having the key size used for
encrypting the link. For example, some profiles may restrict
some operations depending on the key length.
The key size is stored in the key that is passed to userspace
using the pin_length field in the key structure.
For now this field is only valid for LE controllers. 3.0+HS
controllers define the Read Encryption Key Size command, this
field is intended for storing the value returned by that
command.

Bluetooth: Fix __hci_request synchronization for hci_open_dev
The initialization function used by hci_open_dev (hci_init_req) sends
many different HCI commands. The __hci_request function should only
return when all of these commands have completed (or a timeout occurs).
Several of these commands cause hci_req_complete to be called which
causes __hci_request to return prematurely.
This patch fixes the issue by adding a new hdev->req_last_cmd variable
which is set during the initialization procedure. The hci_req_complete
function will no longer mark the request as complete until the command
matching hdev->req_last_cmd completes.

Bluetooth: Automate remote name requests
In Bluetooth there are no automatic updates of remote device names when
they get changed on the remote side. Instead, it is a good idea to do a
manual name request when a new connection gets created (for whatever
reason) since at this point it is very cheap (no costly baseband
connection creation needed just for the sake of the name request).
So far userspace has been responsible for this extra name request but
tighter control is needed in order not to flood Bluetooth controllers
with two many commands during connection creation. It has been shown
that some controllers simply fail to function correctly if they get too
many (almost) simultaneous commands during connection creation. The
simplest way to acheive better control of these commands is to move
their sending completely to the kernel side.
This patch inserts name requests into the sequence of events that the
kernel performs during connection creation. It does this after the
remote features have been successfully requested and before any pending
authentication requests are performed. The code will work sub-optimally
with userspace versions that still do the name requesting themselves (it
shouldn't break anything though) so it is recommended to combine this
with a userspace software version that doesn't have automated name
requests.

Bluetooth: Fix non-SSP auth request for HIGH security level sockets
When initiating dedicated bonding a L2CAP raw socket with HIGH security
level is used. The kernel is supposed to trigger the authentication
request in this case but this doesn't happen currently for non-SSP
(pre-2.1) devices. The reason is that the authentication request happens
in the remote extended features callback which never gets called for
non-SSP devices. This patch fixes the issue by requesting also
authentiation in the (normal) remote features callback in the case of
non-SSP devices.
This rule is applied only for HIGH security level which might at first
seem unintuitive since on the server socket side MEDIUM is already
enough for authentication. However, for the clients we really want to
prefer the server side to decide the authentication requrement in most
cases, and since most client sockets use MEDIUM it's better to be
avoided on the kernel side for these sockets. The important socket to
request it for is the dedicated bonding one and that socket uses HIGH
security level.
The patch is based on the initial investigation and patch proposal from
Andrei Emeltchenko <endrei.emeltchenko@nokia.com>.

Bluetooth: Fallback eSCO to SCO on error 0x1a (Unsupported Remote Feature)
General Motors carkits that use LGE BT chipsets return this error code
when an eSCO is attempted, despite advertising eSCO support.

Bluetooth: Unobfuscate tasklet_schedule usage
The tasklet schedule function helpers are just an obfuscation. So remove
them and call the schedule functions directly.

Bluetooth: Add extra device reference counting for connections
The device model itself has no real usable reference counting at the
moment and this causes problems if parents are deleted before their
children. The device model itself handles the memory details of this
correctly, but the uevent order is not consistent. This causes various
problems for systems like HAL or even X.
So until device_put() does a proper cleanup, the device for Bluetooth
connection will be protected with an extra reference counting to ensure
the correct order of uevents when connections are terminated.
This is not an automatic feature. Higher Bluetooth layers like HIDP or
BNEP should grab this new reference to ensure that their uevents are
send before the ones from the parent device.

Bluetooth: Don't trigger disconnect timeout for security mode 3 pairing
A remote device in security mode 3 that tries to connect will require
the pairing during the connection setup phase. The disconnect timeout
is now triggered within 10 milliseconds and causes the pairing to fail.
If a connection is not fully established and a PIN code request is
received, don't trigger the disconnect timeout. The either successful
or failing connection complete event will make sure that the timeout
is triggered at the right time.
The biggest problem with security mode 3 is that many Bluetooth 2.0
device and before use a temporary security mode 3 for dedicated
bonding.

Bluetooth: Add different pairing timeout for Legacy Pairing
The Bluetooth stack uses a reference counting for all established ACL
links and if no user (L2CAP connection) is present, the link will be
terminated to save power. The problem part is the dedicated pairing
when using Legacy Pairing (Bluetooth 2.0 and before). At that point
no user is present and pairing attempts will be disconnected within
10 seconds or less. In previous kernel version this was not a problem
since the disconnect timeout wasn't triggered on incoming connections
for the first time. However this caused issues with broken host stacks
that kept the connections around after dedicated pairing. When the
support for Simple Pairing got added, the link establishment procedure
needed to be changed and now causes issues when using Legacy Pairing
When using Simple Pairing it is possible to do a proper reference
counting of ACL link users. With Legacy Pairing this is not possible
since the specification is unclear in some areas and too many broken
Bluetooth devices have already been deployed. So instead of trying to
deal with all the broken devices, a special pairing timeout will be
introduced that increases the timeout to 60 seconds when pairing is
triggered.
If a broken devices now puts the stack into an unforeseen state, the
worst that happens is the disconnect timeout triggers after 120 seconds
instead of 4 seconds. This allows successful pairings with legacy and
broken devices now.

Bluetooth: Add workaround for wrong HCI event in eSCO setup
The Broadcom chips with 2.1 firmware handle the fallback case to a SCO
link wrongly when setting up eSCO connections.
< HCI Command: Setup Synchronous Connection (0x01|0x0028) plen 17
handle 11 voice setting 0x0060
> HCI Event: Command Status (0x0f) plen 4
Setup Synchronous Connection (0x01|0x0028) status 0x00 ncmd 1
> HCI Event: Connect Complete (0x03) plen 11
status 0x00 handle 1 bdaddr 00:1E:3A:xx:xx:xx type SCO encrypt 0x01
The Link Manager negotiates the fallback to SCO, but then sends out
a Connect Complete event. This is wrong and the Link Manager should
actually send a Synchronous Connection Complete event if the Setup
Synchronous Connection has been used. Only the remote side is allowed
to use Connect Complete to indicate the missing support for eSCO in
the host stack.
This patch adds a workaround for this which clearly should not be
needed, but reality is that broken Broadcom devices are deployed.

Bluetooth: Fallback from eSCO to SCO on unspecified error
Some Bluetooth chips (like the ones from Texas Instruments) don't do
proper eSCO negotiations inside the Link Manager. They just return an
error code and in case of the Kyocera ED-8800 headset it is just a
random error.
< HCI Command: Setup Synchronous Connection 0x01|0x0028) plen 17
handle 1 voice setting 0x0060
> HCI Event: Command Status (0x0f) plen 4
Setup Synchronous Connection (0x01|0x0028) status 0x00 ncmd 1
> HCI Event: Synchronous Connect Complete (0x2c) plen 17
status 0x1f handle 257 bdaddr 00:14:0A:xx:xx:xx type eSCO
Error: Unspecified Error
In these cases it is up to the host stack to fallback to a SCO setup
and so retry with SCO parameters.

The reason is due to hci_conn_del_sysfs now called in hci_event_packet,
the del work is done in a workqueue, so it's possible done before
skb_queue_purge called.
I move the hci_conn_del_sysfs after skb_queue_purge just as that before

Remove the hci_conn_del_sysfs in hci_conn_hash_flush as well due to
hci_conn_del will deal with the work.

Bluetooth: Ask upper layers for HCI disconnect reason
Some of the qualification tests demand that in case of failures in L2CAP
the HCI disconnect should indicate a reason why L2CAP fails. This is a
bluntly layer violation since multiple L2CAP connections could be using
the same ACL and thus forcing a disconnect reason is not a good idea.
To comply with the Bluetooth test specification, the disconnect reason
is now stored in the L2CAP connection structure and every time a new
L2CAP channel is added it will set back to its default. So only in the
case where the L2CAP channel with the disconnect reason is really the
last one, it will propagated to the HCI layer.
The HCI layer has been extended with a disconnect indication that allows
it to ask upper layers for a disconnect reason. The upper layer must not
support this callback and in that case it will nicely default to the
existing behavior. If an upper layer like L2CAP can provide a disconnect
reason that one will be used to disconnect the ACL or SCO link.
No modification to the ACL disconnect timeout have been made. So in case
of Linux to Linux connection the initiator will disconnect the ACL link
before the acceptor side can signal the specific disconnect reason. That
is perfectly fine since Linux doesn't make use of this value anyway. The
L2CAP layer has a perfect valid error code for rejecting connection due
to a security violation. It is unclear why the Bluetooth specification
insists on having specific HCI disconnect reason.

Bluetooth: Add SCO fallback for eSCO connection attempts
When attempting to setup eSCO connections it can happen that some link
manager implementations fail to properly negotiate the eSCO parameters
and thus fail the eSCO setup. Normally the link manager is responsible
for the negotiation of the parameters and actually fallback to SCO if
no agreement can be reached. In cases where the link manager is just too
stupid, then at least try to establish a SCO link if eSCO fails.
For the Bluetooth devices with EDR support this includes handling packet
types of EDR basebands. This is particular tricky since for the EDR the
logic of enabling/disabling one specific packet type is turned around.
This fix contains an extra bitmask to disable eSCO EDR packet when
trying to fallback to a SCO connection.

Bluetooth: Add enhanced security model for Simple Pairing
The current security model is based around the flags AUTH, ENCRYPT and
SECURE. Starting with support for the Bluetooth 2.1 specification this is
no longer sufficient. The different security levels are now defined as
SDP, LOW, MEDIUM and SECURE.
Previously it was possible to set each security independently, but this
actually doesn't make a lot of sense. For Bluetooth the encryption depends
on a previous successful authentication. Also you can only update your
existing link key if you successfully created at least one before. And of
course the update of link keys without having proper encryption in place
is a security issue.
The new security levels from the Bluetooth 2.1 specification are now
used internally. All old settings are mapped to the new values and this
way it ensures that old applications still work. The only limitation
is that it is no longer possible to set authentication without also
enabling encryption. No application should have done this anyway since
this is actually a security issue. Without encryption the integrity of
the authentication can't be guaranteed.
As default for a new L2CAP or RFCOMM connection, the LOW security level
is used. The only exception here are the service discovery sessions on
PSM 1 where SDP level is used. To have similar security strength as with
a Bluetooth 2.0 and before combination key, the MEDIUM level should be
used. This is according to the Bluetooth specification. The MEDIUM level
will not require any kind of man-in-the-middle (MITM) protection. Only
the HIGH security level will require this.

When the remote device supports only SCO connections, on receipt of

[Bluetooth] Fix reference counting during ACL config stage
The ACL config stage keeps holding a reference count on incoming
connections when requesting the extended features. This results in
keeping an ACL link up without any users. The problem here is that
the Bluetooth specification doesn't define an ownership of the ACL
link and thus it can happen that the implementation on the initiator
side doesn't care about disconnecting unused links. In this case the
acceptor needs to take care of this.

[Bluetooth] Use a more unique bus name for connections
When attaching Bluetooth low-level connections to the bus, the bus name
is constructed from the remote address since at that time the connection
handle is not assigned yet. This has worked so far, but also caused a
lot of troubles. It is better to postpone the creation of the sysfs
entry to the time when the connection actually has been established
and then use its connection handle as unique identifier.

With Bluetooth 2.1 and Simple Pairing the requirement is that any new
connection needs to be authenticated and that encryption has been
switched on before allowing L2CAP to use it. So make sure that all

a minimal disconnect timeout of 10 milliseconds.
This change only affects Bluetooth 2.1 devices and Simple Pairing

[Bluetooth] Use ACL config stage to retrieve remote features
The Bluetooth technology introduces new features on a regular basis
and for some of them it is important that the hardware on both sides
support them. For features like Simple Pairing it is important that
the host stacks on both sides have switched this feature on. To make
valid decisions, a config stage during ACL link establishment has been
introduced that retrieves remote features and if needed also the remote
extended features (known as remote host features) before signalling
this link as connected.
This change introduces full reference counting of incoming and outgoing
ACL links and the Bluetooth core will disconnect both if no owner of it
is present. To better handle interoperability during the pairing phase
the disconnect timeout for incoming connections has been increased to
10 seconds. This is five times more than for outgoing connections.

[Bluetooth] Track status of remote Simple Pairing mode
The Simple Pairing process can only be used if both sides have the
support enabled in the host stack. The current Bluetooth specification
has three ways to detect this support.
If an Extended Inquiry Result has been sent during inquiry then it
is safe to assume that Simple Pairing is enabled. It is not allowed
to enable Extended Inquiry without Simple Pairing. During the remote
name request phase a notification with the remote host supported
features will be sent to indicate Simple Pairing support. Also the
second page of the remote extended features can indicate support for
Simple Pairing.
For all three cases the value of remote Simple Pairing mode is stored
in the inquiry cache for later use.

[Bluetooth] Track connection packet type changes
The connection packet type can be changed after the connection has been
established and thus needs to be properly tracked to ensure that the
host stack has always correct and valid information about it.
On incoming connections the Bluetooth core switches the supported packet
types to the configured list for this controller. However the usefulness
of this feature has been questioned a lot. The general consent is that
every Bluetooth host stack should enable as many packet types as the
hardware actually supports and leave the decision to the link manager
software running on the Bluetooth chip.
When running on Bluetooth 2.0 or later hardware, don't change the packet
type for incoming connections anymore. This hardware likely supports
Enhanced Data Rate and thus leave it completely up to the link manager
to pick the best packet type.

[Bluetooth] Update authentication status after successful encryption
The authentication status is not communicated to both parties. This is
actually a flaw in the Bluetooth specification. Only the requesting side
really knows if the authentication was successful or not. This piece of
information is however needed on the other side to know if it has to
trigger the authentication procedure or not. Worst case is that both
sides will request authentication at different times, but this should
be avoided since it costs extra time when setting up a new connection.
For Bluetooth encryption it is required to authenticate the link first
and the encryption status is communicated to both sides. So when a link
is switched to encryption it is possible to update the authentication
status since it implies an authenticated link.

[PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

[Bluetooth] Handling pending connect attempts after inquiry
After an inquiry completed or got canceled the Bluetooth core should
check for any pending connect attempts.

[Bluetooth] Support concurrent connect requests
Most Bluetooth chips don't support concurrent connect requests, because
this would involve a multiple baseband page with only one radio. In the
case an upper layer like L2CAP requests a concurrent connect these chips
return the error "Command Disallowed" for the second request. If this
happens it the responsibility of the Bluetooth core to queue the request
and try again after the previous connect attempt has been completed.

[Bluetooth]: Don't update disconnect timer for incoming connections
In the case of device pairing the only safe method is to establish
a low-level ACL link. In this case, the remote side should not use
the disconnect timer to give the other side the chance to enter the
PIN code. If the disconnect timer is used, the connection will be
dropped to soon, because it is impossible to identify an actual user
of this link.

[Bluetooth] Support create connection cancel command
In case of non-blocking connects it is possible that the last user
of an ACL link quits before the connection has been fully established.
This will lead to a race condition where the internal state of a
connection is closed, but the actual link has been established and is
active. In case of Bluetooth 1.2 and later devices it is possible to
call create connection cancel to abort the connect. For older devices
the disconnect timer will be used to trigger the needed disconnect.

disappeared, along with register_chrdev(SOCKET_MAJOR, "socket", &net_fops)

Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
