* [PATCH] Bluetooth: btintel_pcie: Remove unused ret in btintel_pcie_submit_rx_work()
From: Robertus Diawan Chris @ 2026-04-30  4:05 UTC (permalink / raw)
  To: marcel, luiz.dentz
  Cc: linux-bluetooth, linux-kernel, linux-kernel-mentees, skhan, me

The variable ret assigned to -EINVAL, however, this value is never read
and re-assigned a new value when the code jumps to label resubmit.
The assignment is redundant and can be removed.

This is reported by Coverity Scan with CID 1598882 as UNUSED_VALUE.

* [RFC PATCH] Bluetooth: fix Set Public Address on controller in HCI_AUTO_OFF grace period
From: Dan Klishch @ 2026-04-30  4:55 UTC (permalink / raw)
  To: Marcel Holtmann, Luiz Augusto von Dentz; +Cc: linux-bluetooth, linux-kernel

When mgmt's Set Public Address command (and Set External Configuration)
stages a configuration change, set_public_address() sets HCI_CONFIG and
HCI_AUTO_OFF on the device and queues hci_power_on. The intent is for
the queued power_on to run hci_dev_init_sync() -- which detects
HCI_CONFIG and calls hdev->set_bdaddr() to program the new address into
the firmware -- and then re-emit Index Added with the controller back in
the boot-init grace period (HCI_UP=1, HCI_AUTO_OFF=1) so userspace can
re-push pending config commands and drive a fresh Set Powered 1 cycle.

The bug bites when the command is issued while the controller is in
that same grace period itself -- the normal post-boot state, before
bluetoothd has claimed the controller via Set Powered 1. In that state
HCI_UP=1 and HCI_AUTO_OFF=1, so hdev_is_powered() is false (the command
is accepted) but hci_power_on()'s "already up" early-return condition
HCI_UP && HCI_MGMT && HCI_AUTO_OFF is true. The early-return path runs
hci_powered_update_sync() -- which is the wrong thing for this case:
neither hci_dev_init_sync() nor mgmt_index_added() runs. The result:

  - hdev->public_addr is recorded but never reaches the firmware via
    hdev->set_bdaddr(),
  - userspace sees Index Removed (from set_public_address) but no
    Index Added, leaving the controller invisible to mgmt clients;
    it is not in the configured, unconfigured or extended index list
    yet remains registered in the kernel.

The other two starting states are fine: HCI_UP=0 falls through to the
full hci_dev_do_open() path (correct); HCI_UP=1 with HCI_AUTO_OFF=0
makes hdev_is_powered() true, so set_public_address() rejects with
MGMT_STATUS_REJECTED before queueing power_on at all.

Fix: at the top of hci_power_on(), if HCI_CONFIG is pending and we are
in the affected grace-period state (HCI_UP, HCI_MGMT, !HCI_RFKILLED),
close the device first. The early-return condition then fails and we
fall through to hci_dev_do_open() -> hci_dev_init_sync(), which honors
HCI_CONFIG by invoking hdev->set_bdaddr(); the post-open block then
re-emits Index Added via the existing HCI_CONFIG branch.

hci_dev_close_sync() clears HCI_AUTO_OFF as a side effect of going
through the regular power-down path, but set_public_address() had set
it deliberately so the post-reopen state matches the boot-init grace
period that mgmt clients expect ("treat as new one" per the protocol
contract). Several mgmt commands -- Set Privacy, Set Wideband Speech,
Set LE, Set BR/EDR, etc. -- gate on !hdev_is_powered(), and bluetoothd
expects to push them during this window before issuing Set Powered 1
itself. Restore HCI_AUTO_OFF after the close so hdev_is_powered() ==
false again.

This matches the documented behavior for Set Public Address on a
fully-configured controller ("Once the address has been successfully
changed an Index Added event will be sent.")

Claude was able to fully convince me that the patch and the explanation
are correct. Moreover, this indeed fixed a problem I had with a custom
patched bluetoothd that happened to override public-addr in the 2
second post-boot window. However, both the patch and commit description
are fully AI-generated.

This should not be a separate patch. You add the layout AND you use it.

This looks incomplete. Why isn't this mac-base type of entry? And how do
you address it from NVMEM consumer?

This indeed falls under the fixed-cell/mac-base type, thanks for
pointing that out.
NVMEM consumers reference these entries using the nvmem-cells
property, via the corresponding label/phandle.

  audio: Add ability to desynchronized linked transport

If bluetoothd is started in testing mode a new Desynchronized property
is added, allowing to prevent automatic acquire of linked transport
objects.

When desynchronized, each transports needs to be acquired separately.

This allows to pass PTS tests BAP/UCL/STR/BV-543-C and BV-546-C.

* [RFC PATCH BlueZ 1/3] shared/hci: Add BPF filter for registered events
From: Luiz Augusto von Dentz @ 2026-04-30 15:50 UTC (permalink / raw)
  To: linux-bluetooth

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Implement a BPF socket filter in bt_hci_register/bt_hci_unregister that
uses setsockopt(SO_ATTACH_FILTER) to only accept HCI events that have
been registered, plus BT_HCI_EVT_CMD_COMPLETE and BT_HCI_EVT_CMD_STATUS
which are always needed for command response processing.

The filter is rebuilt each time an event is registered or unregistered,
and only applies to non-stream (raw socket) connections.

* [RFC PATCH BlueZ 2/3] shared/hci: Add bt_hci_register_subevent for LE Meta events
From: Luiz Augusto von Dentz @ 2026-04-30 15:50 UTC (permalink / raw)
  To: linux-bluetooth
In-Reply-To: <20260430155038.426968-1-luiz.dentz@gmail.com>

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Add bt_hci_register_subevent/bt_hci_unregister_subevent API that allows
registering for specific LE Meta Event subevents. The BPF filter is
extended to accept BT_HCI_EVT_LE_META_EVENT packets and then check the
subevent byte (offset 4) against registered subevents.

Since bt_hci_register_subevent is only used with BT_HCI_EVT_LE_META_EVENT,
the event parameter is omitted. The subevent list reuses struct evt where
evt->event stores the subevent code.

* [RFC PATCH BlueZ 3/3] ranging/rap_hci: Use bt_hci_register_subevent for LE CS events
From: Luiz Augusto von Dentz @ 2026-04-30 15:50 UTC (permalink / raw)
  To: linux-bluetooth
In-Reply-To: <20260430155038.426968-1-luiz.dentz@gmail.com>

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Replace the single BT_HCI_EVT_LE_META_EVENT registration and subevent
dispatch table with individual bt_hci_register_subevent calls for each
CS subevent. This enables BPF filtering at the socket level for each
specific subevent and removes the manual subevent dispatch logic.

Event IDs are stored in a struct queue for flexible management.
