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.

[Bluetooth] Switch from OGF+OCF to using only opcodes The Bluetooth HCI commands are divided into logical OGF groups for easier identification of their purposes. While this still makes sense for the written specification, its makes the code only more complex and harder to read. So instead of using separate OGF and OCF values to identify the commands, use a common 16-bit opcode that combines both values. As a side effect this also reduces the complexity of OGF and OCF calculations during command header parsing. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

[Bluetooth] Switch from OGF+OCF to using only opcodes The Bluetooth HCI commands are divided into logical OGF groups for easier identification of their purposes. While this still makes sense for the written specification, its makes the code only more complex and harder to read. So instead of using separate OGF and OCF values to identify the commands, use a common 16-bit opcode that combines both values. As a side effect this also reduces the complexity of OGF and OCF calculations during command header parsing. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

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. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

[Bluetooth] Initiate authentication during connection establishment 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 the requirements are fulfilled and otherwise drop the connection with a minimal disconnect timeout of 10 milliseconds. This change only affects Bluetooth 2.1 devices and Simple Pairing needs to be enabled locally and in the remote host stack. The previous changes made sure that these information are discovered before any kind of authentication and encryption is triggered. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

[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: 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] 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: 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. Based on a report by Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

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] 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. This also fixes the case where two different adapters try to connect to the same remote device. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

[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] Add support for handling simple eSCO links With the Bluetooth 1.2 specification the Extended SCO feature for better audio connections was introduced. So far the Bluetooth core wasn't able to handle any eSCO connections correctly. This patch adds simple eSCO support while keeping backward compatibility with older devices.

[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. This also fixes the case where two different adapters try to connect to the same remote device. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

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. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

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. Based on a report by Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

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.

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. Based on a report by Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

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] 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. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

[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] 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: 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. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

[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. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

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] 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. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

[Bluetooth] Switch from OGF+OCF to using only opcodes The Bluetooth HCI commands are divided into logical OGF groups for easier identification of their purposes. While this still makes sense for the written specification, its makes the code only more complex and harder to read. So instead of using separate OGF and OCF values to identify the commands, use a common 16-bit opcode that combines both values. As a side effect this also reduces the complexity of OGF and OCF calculations during command header parsing. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

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!
