* Bluetooth: Pass initiator/acceptor information to hci_conn_security()Johan Hedberg2014-07-17
| | | | | | | | | | | | | | | We're interested in whether an authentication request is because of a remote or local action. So far hci_conn_security() has been used both for incoming and outgoing actions (e.g. RFCOMM or L2CAP connect requests) so without some modifications it cannot know which peer is responsible for requesting authentication. This patch adds a new "bool initiator" parameter to hci_conn_security() to indicate which side is responsible for the request and updates the current users to pass this information correspondingly.

* Bluetooth: Convert L2CAP ident spinlock into a mutexMarcel Holtmann2014-07-13

* Bluetooth: Provide L2CAP ops callback for memcpy_fromiovecJukka Rissanen2014-07-03
| | | | | | | | | | | | | | | | | | | The highly optimized TX path for L2CAP channels and its fragmentation within the HCI ACL packets requires to copy data from user provided IO vectors and also kernel provided memory buffers. This patch allows channel clients to provide a memcpy_fromiovec callback to keep this optimized behavior, but adapt it to kernel vs user memory for the TX path. For all kernel internal L2CAP channels, a default implementation is provided that can be referenced. In case of A2MP, this fixes a long-standing issue with wrongly accessing kernel memory as user memory. This patch originally by Marcel Holtmann.

* Bluetooth: Fix updating Identity Address in L2CAP channelsJohan Hedberg2014-02-18
| | | | | | | | | | | | | | When we receive a remote identity address during SMP key distribution we should ensure that any associated L2CAP channel instances get their address information correspondingly updated (so that e.g. doing getpeername on associated sockets returns the correct address). This patch adds a new L2CAP core function l2cap_conn_update_id_addr() which is used to iterate through all L2CAP channels associated with a connection and update their address information.

* Bluetooth: Rename L2CAP_CHAN_CONN_FIX_A2MP to L2CAP_CHAN_FIXEDJohan Hedberg2014-02-13
| | | | | | | | | | | | | | There's no reason why A2MP should need or deserve its on channel type. Instead we should be able to group all fixed CID users under a single channel type and reuse as much code as possible for them. Where CID specific exceptions are needed the chan-scid value can be used. This patch renames the current A2MP channel type to a generic one and thereby paves the way to allow converting ATT and SMP (and any future fixed channel protocols) to use the new channel type.

* Bluetooth: Queue incoming ACL data until BT_CONNECTED state is reachedJohan Hedberg2014-02-13
| | | | | | | | | | | | | | | This patch adds a queue for incoming L2CAP data that's received before l2cap_connect_cfm is called and processes the data once l2cap_connect_cfm is called. This way we ensure that we have e.g. all remote features before processing L2CAP signaling data (which is very important for making the correct security decisions). The processing of the pending rx data needs to be done through queue_work since unlike l2cap_recv_acldata, l2cap_connect_cfm is called with the hci_dev lock held which could cause potential deadlocks.

* Bluetooth: Simplify l2cap_chan initialization for LE CoCJohan Hedberg2013-12-05
| | | | | | | | | | | | | | | | The values in l2cap_chan that are used for actually transmitting data only need to be initialized right after we've received an L2CAP Connect Request or just before we send one. The only thing that we need to initialize though bind() and connect() is the chan->mode value. This way all other initializations can be done in the l2cap_le_flowctl_init function (which now becomes private to l2cap_core.c) and the l2cap_le_flowctl_start function can be completely removed. Also, since the l2cap_sock_init function initializes the imtu and omtu to adequate values these do not need to be part of l2cap_le_flowctl_init.

If we create two different functions for this we would need to release the lock between the two operation putting the socket in non desired state. The change is transparent to the l2cap_core.c code, user that only needs to set the state won't need any modification.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The L2CAP sockets can use BR/EDR public, LE public and LE random addresses for various combinations of source and destination devices. So make sure that getsockname(), getpeername() and accept() return the correct address type. For this the address type of the source and destination is stored with the L2CAP channel information. The stored address type is not the one specific for the HCI protocol. It is the address type used for the L2CAP sockets and the management interface. The underlying HCI connections store the HCI address type. If needed, it gets converted to the socket address type.

* Bluetooth: l2cap: add l2cap_user sub-modulesDavid Herrmann2013-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several sub-modules like HIDP, rfcomm, ... need to track l2cap connections. The l2cap_conn->hcon->dev object is used as parent for sysfs devices so the sub-modules need to be notified when the hci_conn object is removed from sysfs. As submodules normally use the l2cap layer, the l2cap_user objects are registered there instead of on the underlying hci_conn object. This avoids any direct dependency on the HCI layer and lets the l2cap core handle any specifics. This patch introduces l2cap_user objects which contain a "probe" and "remove" callback. You can register them on any l2cap_conn object and if it is active, the "probe" callback will get called. Otherwise, an error is returned. The l2cap_conn object will call your "remove" callback directly before it is removed from user-space. This allows you to remove your submodules _before_ the parent l2cap_conn and hci_conn object is removed. At any time you can asynchronously unregister your l2cap_user object if your submodule vanishes before the l2cap_conn object does. There is no way around l2cap_user. If we want wire-protocols in the kernel, we always want the hci_conn object as parent in the sysfs tree. We cannot use a channel here since we might need multiple channels for a single protocol. But the problem is, we _must_ get notified when an l2cap_conn object is removed. We cannot use reference-counting for object-removal! This is not how it works. If a hardware is removed, we should immediately remove the object from sysfs. Any other behavior would be inconsistent with the rest of the system. Also note that device_del() might sleep, but it doesn't wait for user-space or block very long. It only _unlinks_ the object from sysfs and the whole device-tree. Everything else is handled by ref-counts! This is exactly what the other sub-modules must do: unlink their devices when the "remove" l2cap_user callback is called. They should not do any cleanup or synchronous shutdowns.

| | | | | | | | | | | | | | | | If we want to use l2cap_conn outside of l2cap_core.c, we need refcounting for these objects. Otherwise, we cannot synchronize l2cap locks with outside locks and end up with deadlocks. Hence, introduce ref-counting for l2cap_conn objects. This doesn't affect l2cap internals at all, as they use a direct synchronization. We also keep a reference to the parent hci_conn for locking purposes as l2cap_conn depends on this.
