2024-11-14Bluetooth: hci_bcm: Use the devm_clk_get_optional() helperAndy Shevchenko
Use devm_clk_get_optional() instead of hand writing it. This saves some LoC and improves the semantic. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
2024-11-14Bluetooth: ISO: Send BIG Create Sync via hci_syncIulia Tanasescu
Before issuing the LE BIG Create Sync command, an available BIG handle is chosen by iterating through the conn_hash list and finding the first unused value. If a BIG is terminated, the associated hcons are removed from the list and the LE BIG Terminate Sync command is sent via hci_sync queue. However, a new LE BIG Create sync command might be issued via hci_send_cmd, before the previous BIG sync was terminated. This can cause the same BIG handle to be reused and the LE BIG Create Sync to fail with Command Disallowed. < HCI Command: LE Broadcast Isochronous Group Create Sync (0x08|0x006b) BIG Handle: 0x00 BIG Sync Handle: 0x0002 Encryption: Unencrypted (0x00) Broadcast Code[16]: 00000000000000000000000000000000 Maximum Number Subevents: 0x00 Timeout: 20000 ms (0x07d0) Number of BIS: 1 BIS ID: 0x01 > HCI Event: Command Status (0x0f) plen 4 LE Broadcast Isochronous Group Create Sync (0x08|0x006b) ncmd 1 Status: Command Disallowed (0x0c) < HCI Command: LE Broadcast Isochronous Group Terminate Sync (0x08|0x006c) BIG Handle: 0x00 This commit fixes the ordering of the LE BIG Create Sync/LE BIG Terminate Sync commands, to make sure that either the previous BIG sync is terminated before reusing the handle, or that a new handle is chosen for a new sync.

This make use of kref to keep track of reference of iso_conn which allows better tracking of its lifetime with usage of things like kref_get_unless_zero in a similar way as used in l2cap_chan. In addition to it remove call to iso_sock_set_timer on iso_sock_disconn since at that point it is useless to set a timer as the sk will be freed there is nothing to be done in iso_sock_timeout.

In order to avoid this issue, the HCI_CONN_CREATE_BIG_SYNC was added to mark that the LE BIG Create Sync command has been sent for a hcon. Once the BIG Sync Established event is received, the hcon flag is erased and the next pending hcon is handled.

2024-11-14Bluetooth: ISO: Fix matching parent socket for BIS slaveIulia Tanasescu
Currently, when a BIS slave connection is notified to the ISO layer, the parent socket is tried to be matched by the HCI_EVT_LE_BIG_SYNC_ESTABILISHED event. However, a BIS slave connection is notified to the ISO layer after the Command Complete for the LE Setup ISO Data Path command is received. This causes the parent to be incorrectly matched if multiple listen sockets are present. This commit adds a fix by matching the parent based on the BIG handle set in the notified connection.

2024-11-14Bluetooth: btbcm: fix missing of_node_put() in btbcm_get_board_name()Javier Carrasco
of_find_node_by_path() returns a pointer to a device_node with its refcount incremented, and a call to of_node_put() is required to decrement the refcount again and avoid leaking the resource. If 'of_property_read_string_index(root, "compatible", 0, &tmp)' fails, the function returns without calling of_node_put(root) before doing so. The automatic cleanup attribute can be used by means of the __free() macro to automatically call of_node_put() when the variable goes out of scope, fixing the issue and also accounting for new error paths.

2024-11-14Bluetooth: Fix type of len in rfcomm_sock_getsockopt{,_old}()Andrej Shadura
Commit 9bf4e919ccad worked around an issue introduced after an innocuous optimisation change in LLVM main: > len is defined as an 'int' because it is assigned from > '__user int *optlen'. However, it is clamped against the result of > sizeof(), which has a type of 'size_t' ('unsigned long' for 64-bit > platforms). This is done with min_t() because min() requires compatible > types, which results in both len and the result of sizeof() being casted > to 'unsigned int', meaning len changes signs and the result of sizeof() > is truncated. From there, len is passed to copy_to_user(), which has a > third parameter type of 'unsigned long', so it is widened and changes > signs again. This excessive casting in combination with the KCSAN > instrumentation causes LLVM to fail to eliminate the __bad_copy_from() > call, failing the build. The same issue occurs in rfcomm in functions rfcomm_sock_getsockopt and rfcomm_sock_getsockopt_old. Change the type of len to size_t in both rfcomm_sock_getsockopt and rfcomm_sock_getsockopt_old and replace min_t() with min().

2024-11-14Bluetooth: btintel_pcie: Add handshake between driver and firmwareKiran K
The following handshake mechanism needs be followed after firmware download is completed to bring the firmware to running state. After firmware fragments of Operational image are downloaded and secure sends result of the image succeeds, 1. Driver sends HCI Intel reset with boot option #1 to switch FW image. 2. FW sends Alive GP[0] MSIx 3. Driver enables data path (doorbell 0x460 for RBDs, etc...) 4. Driver gets Bootup event from firmware 5. Driver performs D0 entry to device (WRITE to IPC_Sleep_Control =0x0) 6. FW sends Alive GP[0] MSIx 7. Device host interface is fully set for BT protocol stack operation. 8. Driver may optionally get debug event with ID 0x97 which can be dropped For Intermediate loadger image, all the above steps are applicable expcept #5 and #6. On HCI_OP_RESET, firmware raises alive interrupt. Driver needs to wait for it before passing control over to bluetooth stack.

2024-11-14sched_ext: ops.cpu_acquire() should be called with SCX_KF_RESTTejun Heo
ops.cpu_acquire() is currently called with 0 kf_maks which is interpreted as SCX_KF_UNLOCKED which allows all unlocked kfuncs, but ops.cpu_acquire() is called from balance_one() under the rq lock and should only be allowed call kfuncs that are safe under the rq lock. Update it to use SCX_KF_REST.
