Or we could just add a kref to mgmt_pending_cmd so mgmt_pending_find
can return a reference which is then unref'd when finished accessing
it.

* [Bug 221666] New: Regression in 7.1: Kernel Oops in hidinput_setup_battery (hid_microsoft) causing uhid deadlock when pairing Xbox controller
From: bugzilla-daemon @ 2026-06-18 17:14 UTC (permalink / raw)
To: linux-bluetooth
https://bugzilla.kernel.org/show_bug.cgi?id=221666
Bug ID: 221666
Summary: Regression in 7.1: Kernel Oops in
hidinput_setup_battery (hid_microsoft) causing uhid
deadlock when pairing Xbox controller
Product: Drivers
Version: 2.5
Hardware: All
OS: Linux
Status: NEW
Severity: blocking
Priority: P3
Component: Bluetooth
Assignee: linux-bluetooth@vger.kernel.org
Reporter: intellq@gmail.com
Regression: No
OS: Arch Linux / EndeavourOS
Kernel (Failing): 7.1.0 (TKG and mainline equivalent)
Kernel (Working): 7.0.12 (Arch stable and TKG)
Device: Gulikit KingKong 2 Pro (paired in XInput/Xbox One mode)
Pairing the controller in Xbox One mode via Bluetooth on kernel 7.1 triggers an
immediate Kernel Oops (Page Fault) inside hidinput_setup_battery called by the
hid_microsoft driver.
This initial crash leaves the HID subsystem in a locked state. Consequently,
the bluetoothd daemon enters an Uninterruptible Sleep (D state) deadlock inside
uhid_dev_destroy when attempting to clean up. The Bluetooth service becomes
completely unresponsive, fails to terminate on SIGKILL, and causes the system
to hang indefinitely during shutdown/reboot (watchdog did not stop).
Booting into kernel 7.0.12 completely resolves the issue, and the controller
pairs and reports battery normally. The issue only happens in XInput/Xbox mode
(which uses hid_microsoft). D-Input or Switch mode works fine on 7.1.
Steps to Reproduce:
- Boot kernel 7.1.
- Put the controller in XInput/Xbox mode.
- Attempt to pair via Bluetooth (BlueZ).
- Observe the dmesg Oops and subsequent bluetoothd deadlock.
Kernel Oops Log (The Root Cause):
BUG: unable to handle page fault for address: ffffffffffffffe4

#PF: error_code(0x0000) - not-present page

Thanks for the review and suggestion.
I looked into the kref approach. It does look cleaner, but it changes the
lifetime contract of mgmt_pending_find() and requires auditing all callers
and the removal/completion paths. I am not fully confident I can make that
broader mgmt_pending_cmd lifetime change correctly for this.
If you would prefer to make the kref-based change, I would really
appreciate it and would be happy to keep testing it with my reproducer.
If you would prefer me to respin it instead, I may need more specific
guidance.
Best regards,
Cen Zhang

Does your kernel have this patch?
https://lore.kernel.org/all/20260602030519.3097058-1-rafael@rcpassos.me/
I'll reassign to the HID subsystem as that's where the original problem lies.

Can you provide helper function like devm clk get and enabled?
like devm_pwrsq_get_on()
So simple below error handle.

supposed create_devices only do once.
pci_pwrctrl_power_on_devices() controller on and off for difference case.

--- Comment #2 from Zach (bynxmusic@gmail.com) ---
I've had this motherboard for a few years, and I've never successfully gotten
the bluetooth driver to work, even on older kernel versions.

* [PATCH] Bluetooth: hci_event: Synchronously cancel timers in hci_cmd_complete_evt()
From: Sungwoo Kim @ 2026-06-19 0:42 UTC (permalink / raw)
To: Marcel Holtmann, Luiz Augusto von Dentz, Chethan T N,
Srivatsa Ravishankar, Kiran K, Manish Mandlik
Cc: Sungwoo Kim, Dave Tian, linux-bluetooth, linux-kernel
RFC only.
hci_cmd_complete_evt() and hci_cmd_timeout can interleave, leading to
user-after-free access.
CPU1 CPU2
hci_cmd_timeout()
hci_event_packet()
[snip]
hci_cmd_complete_evt()
handle_cmd_cnt_and_timer()
// this is asynchronous
cancel_delayed_work(&hdev->cmd_timer)
hci_cmd_sync_complete()
kfree_skb(hdev->req_skb); // free
hci_skb_opcode(hdev->req_skb); // use-after-free
To fix this, make cancel_delayed_work() synchronous so it can wait for
the timeout handler.
However, this is not a complete fix because hci_cmd_timeout() resets the
device and queue a new command.
I would like to request for comments the better way to fix this issue.

Funny that syzbot found this ancient bug ten days after the fix landed
in a subsystem tree...
This is fixed by commit 59e932ded949fa6f0340bf7c6d7818f962fa4fd2.

Betreff: Re: [PATCH v2] Bluetooth: btusb: Add support for Quectel
NCM865
Datum: 25.12.2025 08:10:10
Hi Pauli
The reason for adding it to btusb_table is that without this entry, the
device (2c7c:0130) is being detected but defaults to a generic QCA
"Rome" configuration (0x190200), which lacks ISO/LE Audio support.
It is definitely loading the btusb driver, but without the explicit ID
match, the capabilities don't align with the actual WCN785x hardware.
Just a quick heads-up: I'm currently on vacation, so my response time
might be a bit slow. I'm mainly checking my mails and doing tests on
rainy days when I'm staying indoors.

I stumbled on this while backporting to distro kernels, and I wonder
whether this change is correct.
IIUC, this essentially makes the loop exiting right after the first
cycle; the patch changed from time_is_before_jiffies() to *_after_*(),
not only the logical OR to AND, and *_after_*() returns false, so the
whole condition becomes false, too.
thanks,

The intention is for the loop to keep running as long as there is
still an interrupt left to handle (int_status != 0) and the timeout
has not elapsed (jiffies < txrx_timeout).
Note that time_is_after_jiffies(x) returns true if x > jiffies (or jiffies < x):
/**
* time_is_after_jiffies - return true if a is after jiffies
* @a: time (unsigned long) to compare to jiffies
*
* Return: %true is time a is after jiffies, otherwise %false.
*/
#define time_is_after_jiffies(a) time_before(jiffies, a)
Or am I missing something?
Best,
Tomasz

Doh, scratch my comment. It's enough confusing about time_after() vs
time_is_after_jiffies(). Too hot here to review something today :-<

Haha, no worries, it got me too! (In our internal discussion with
Sergey) I had to look up the definition and think about it for quite a
while to ensure it was really what we needed. ;)

* [PATCH] Bluetooth: btrtl: set error code when RTL_SEC_PROJ read fails
From: Yinhao Hu @ 2026-06-20 10:56 UTC (permalink / raw)
To: marcel
Cc: luiz.dentz, linux-bluetooth, dzm91, hust-os-kernel-patches,
Yinhao Hu
btrtl_initialize() returns ERR_PTR(ret) at the err_free label, so every
path that jumps there must leave a negative error code in ret.
The RTL_SEC_PROJ register read stored its result in a separate variable
rc and jumped to err_free on failure without updating ret. At that point
ret is still 0 from the previous successful read, so btrtl_initialize()
returns ERR_PTR(0), i.e. NULL. btrtl_setup_realtek() only checks
IS_ERR(), then passes the NULL pointer to btrtl_download_firmware(),
which dereferences it:
Oops: general protection fault
RIP: btrtl_download_firmware+0x39
btrtl_setup_realtek
btusb_setup_realtek
hci_dev_open_sync
Read the register into ret directly and drop the now-redundant rc so the
failure propagates as a negative error pointer.
Fixes: cd8dbd9ef600 ("Bluetooth: btrtl: Avoid loading the config file on security chips")
