Pull another power sequencing update from Bartosz Golaszewski:
"A single tree-wide rename of two of the public functions to better
reflect their actual semantics:
- rename pwrseq_power_on/off() to pwrseq_enable/disable() tree-wide"
* tag 'pwrseq-updates-for-v7.3-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:
power: sequencing: rename pwrseq_power_on/off() to pwrseq_enable/disable()
|
|
The way power sequencing works means that a call to pwrseq_power_on()
does not necessarily result in the pwrseq target being powered-on at
that time: it may have already been powered on before. Similarly: a call
to pwrseq_power_off() does not have to result in an actual powering off
of resources: there may still be other users that requested a power-on
before.
We will also introduce the concept of "non-controllable" pwrseq targets
soon which further increases the disconnect between the naming
convention and the actual semantics.
What consumers of pwrseq descriptors actually do is: they *vote* for a
powering on of a given target or retract that vote. These operations
could be called get/put in line with runtime PM but this could become
confusing since we already provide pwrseq_get/put() for a different
purpose. pwrseq_vote_on/off() also have been rejected as unusual in
the tree.
Change the name of the two functions to pwrseq_enable/disable() which
better reflects their purpose and semantics and also mirrors other
enable-counted resources like regulators and clocks. No functional change
intended.
If at any point users need to know *when* the exact power event happens,
we can provide that information in the form of a notifier.

Commit 5ead2063611a ("Bluetooth: btrtl: fix RTL8761B/BU broken LE
extended scan") set HCI_QUIRK_BROKEN_EXT_SCAN for every CHIP_ID_8761B
device to cure repeated 0x2042 failures on an 0bda:a728 dongle. The
brokenness is per-dongle, not per-chip: on a TP-Link UB500 (2357:0604,
RTL8761BU, fw 0xdfc6d922) extended scan works, and the legacy scan
path the quirk forces is what is broken -- LE Set Scan Enable (0x200c)
times out with -110 about 30 s after firmware load, btusb resets the
device, and the adapter re-enumerates in an endless loop (382 firmware
reloads in one boot). 7.1.8, which predates the stable backport, runs
clean on this unit; 7.1.9 loops.
Move the quirk from btrtl's chip-wide switch to a btusb device-table
flag on the USB id the original fix was verified against. Other 8761B
dongles return to their earlier long-standing behaviour.

Commit ed2a2ef16a6b ("Bluetooth: Add quirk to ignore reserved PHY bits in
LE Extended Adv Report") added a quirk to handle creative use of the
reserved bits in the PHY fields for 4388 controllers in Apple silicon.
I observed the same issue with the BCM4378 Bluetooth controller (14e4:5f69,
rev 05) on an Apple MacBook Pro (13-inch, M2, 2022):

This results in the firmware rejecting connection attempts with
"Unsupported Feature or Parameter Value" (0x11).
Fix the issue by using the same quirk for BCM4378 devices too.
I tested this locally and confirmed that the issue is resolved.
This was observed when attempting to connect a Kinesis Advantage 360
keyboard to the MacBook.

nxp_process_fw_dump() pulls the ACL header off the frame and then reads
seq_num and buf_len from a struct nxp_fw_dump_hdr placed at skb->data,
without checking that the ACL payload is long enough to contain it.
h4_recv_buf() collects HCI_ACL_HDR_SIZE bytes of header followed by the
number of payload bytes named in that header, so skb->len is 4 + dlen
with dlen supplied by the controller and possibly smaller than the 8
byte dump header, or zero. A short frame with connection handle 0xfff
therefore reads both fields from beyond the received data.
Beyond the read itself, buf_len is what terminates a dump: a value of
zero makes the driver call hci_devcd_complete() and reset the
controller, so a truncated frame can end a dump early.
Use skb_pull_data() to validate and pull the FW dump header before
accessing its fields. Warn and reject the chunk if the header is
truncated.

The current code uses of_graph_is_present() to decide whether to enter
the pwrseq path. However, of_graph_is_present() only checks for the
structural presence of a port/ports sub-node and does not check the
status property. This causes problems when a DT overlay disables the
remote M.2 connector node (e.g., switching from PCIe WiFi to SDIO WiFi):
the port node still exists, so of_graph_is_present() returns true, but
the pwrseq provider never registers because the connector is disabled,
leading to an infinite -EPROBE_DEFER loop.
Replace of_graph_is_present() with a new helper that traverses the OF
graph to the remote port parent (the M.2 connector node) and checks
of_device_is_available(). When the remote connector is disabled, the
pwrseq path is skipped, allowing the BT driver to fall through to the
direct bluetooth child node path.

btmtksdio_tx_packet() rounds the transfer size up to the SDIO block size
of 256 bytes, but hands the host controller the SKB buffer as is:
err = sdio_writesb(bdev->func, MTK_REG_CTDR, skb->data,
round_up(skb->len, MTK_SDIO_BLOCK_SIZE));
Only skb->len bytes hold packet data, so the controller reads up to 255
bytes of uninitialised memory and sends it to the device over the SDIO
bus. Depending on how much tailroom slack the SKB allocation happens to
carry, that read can also extend past the end of the buffer.
Compute the padded length up front, ensure the SKB has tailroom for it,
and zero-fill the padding with skb_put_zero(). skb->len then covers the
padding, so sdio_writesb() no longer needs to round up. byte_tx keeps
counting the header and the payload only, and the error path restores the
SKB so that the caller can requeue it.
Writing behind skb->tail is only safe because the driver owns the buffer,
which "Bluetooth: btmtksdio: Take exclusive ownership of the SKB before
TX" ensures.

btmtksdio_tx_packet() prepends the MediaTek SDIO header with skb_push()
and writes into that space after only checking the headroom size. On a
cloned SKB that headroom belongs to a buffer shared with the other owner,
which the driver has no right to write to.
Cloned SKBs do reach this path: hci_send_cmd_sync() keeps a clone of every
HCI command in hdev->sent_cmd before handing the SKB to the driver, and
l2cap_ertm_send() clones SKBs for retransmission.
Replace the open-coded headroom check with skb_cow_head(), which both
guarantees the headroom and reallocates a private buffer when the SKB is
cloned. The cost is one reallocation and copy per cloned packet, the usual
price of this pattern in network drivers.
This has no observable effect on its own, as the driver only writes in
front of skb->data where no other owner looks. It is a prerequisite for
"Bluetooth: btmtksdio: Fix out-of-bounds DMA read in the TX path", which
writes padding behind skb->tail, and carries the same Fixes: tag so that
both are backported together.

When the MTK_BT_RST_DONE poll times out, btmtk_usb_subsys_reset() logs
"Reset timeout" and keeps the error in err, but err is then overwritten
by the return value of the following btmtk_usb_id_get() call, so the
timeout is never reported to the caller.
Commit 25b6d7593a3a ("Bluetooth: btmtk: introduce btmtk reset work")
discarded the return value of the chip id read, so the function returned
the timeout error as intended. Commit 3dcb122b3064 ("Bluetooth: btusb:
mediatek: return error for failed reg access") started assigning err at
that call and silently dropped it.
Keep the timeout in a separate variable and return it, restoring the
original behaviour without changing the control flow.

btmtk_usb_subsys_reset() validates the subsystem reset by reading the
chip id back. When that read succeeds at the bus level but yields an id
of zero, the reset has demonstrably not taken effect: the function logs
"Can't get device id, subsys reset fail." and then returns the return
value of btmtk_usb_id_get(), which in that case is zero, i.e. success.
btusb_mtk_reset() returns that value unchanged, so its caller cannot
tell a completed reset from a failed one.
Return -ENODEV when the chip id reads back as zero, leaving the existing
MT6639 exemption intact.
Observed on an MT7902 [13d3:3579]. The path can be reached on demand by
asking the controller for a coredump, since btmtk requests a reset once
the dump completes:
# echo 1 > /sys/class/bluetooth/hci0/device/coredump
Bluetooth: hci0: Mediatek coredump end
Bluetooth: hci0: Can't get device id, subsys reset fail.
usb 3-10: reset high-speed USB device number 5 using xhci_hcd
usb 3-10: device descriptor read/64, error -110
usb usb3-port10: attempt power cycle
usb usb3-port10: unable to enumerate USB device
The same sequence occurs unprompted when the controller firmware asserts
on its own.
Note that this corrects the error reporting only; it does not by itself
make the controller recoverable in the case above.

Power supply to the M.2 Bluetooth device attached to the host using M.2
connector is controlled using the 'uart' pwrseq device. So add support
for getting the pwrseq device if the OF graph link is present.
Once obtained, pwrseq_power_on() is called to power up the M.2 Bluetooth
card. The power sequencer descriptor is obtained via pwrseq_get() with
the UART controller device (serdev->ctrl->dev), since the OF graph
link is defined on the UART controller node.
Also add the explicit pwrseq_put() call in all exit paths, pwrseq_put()
already calls pwrseq_power_off() internally, so no separate
pwrseq_power_off() call is needed.

The virtbt_setup_zephyr() sends the Zephyr vendor command 0xfc08 (Read
Build Information) and hands the response to bt_dev_info() and
hci_set_fw_info() as a "%s" string starting at skb->data + 1, without
checking the length. A backend that answers with status only leaves that
pointer past the end of the received data, so the walk reads adjacent
slab memory until it meets a NUL. Those bytes reach the kernel log and
the firmware-info debugfs file.
To fix this, print the string with a bounded "%.*s" limited to
skb->len - 1. A short or unterminated response then prints as much as
arrived instead of failing setup.
This mirrors commit dd068ef04412 ("Bluetooth: bpa10x: avoid OOB read of

Use a named initializer for the acpi_device_id fields which
makes the code more readable and consistent with how lists
are initialized in the rest of the kernel code base.
While we are at it - unify the list terminator to have
a single space between the brackets without a trailing
coma.

For a HCI_VENDOR_PKT frame, hci_recv_frame() does not accept it and
will kfree_skb() it directly.
But btmrvl_sdio_card_to_host() is still calling hci_recv_frame() for
the frame.
Fix by freeing it with kfree_skb() directly.

In rsi_hci_attach(), ops->set_bt_context() stores the newly allocated
h_adapter into common->bt_adapter before hci_alloc_dev() and
hci_register_dev() are called. If either of these fails, h_adapter
is freed but common->bt_adapter remains a non-NULL dangling pointer.
This causes a deterministically reachable use-after-free when the
device operates in a BT+WiFi coexistence mode and CONFIG_RSI_COEX
is enabled. The following software-only trigger paths exist:
1. SDIO driver .remove (rsi_disconnect)
2. USB driver .disconnect (rsi_disconnect)
3. SDIO driver .shutdown (rsi_shutdown)
4. Hibernation .freeze (rsi_freeze)
All four paths check:
if (IS_ENABLED(CONFIG_RSI_COEX) && coex_mode > 1 && bt_adapter)
rsi_bt_ops.detach(bt_adapter); // use-after-free
coex_mode is set during rsi_91x_init(), before rsi_hci_attach() is
called, and is not cleared on attach failure. Since set_bt_context()
already wrote bt_adapter before the failure, the deinit paths see a
non-NULL dangling pointer and proceed to detach it.
Fix this by moving set_bt_context() after hci_register_dev() succeeds.
On failure paths bt_adapter stays NULL, and the deinit callers correctly
skip the detach call.

The reset path had two concurrency holes. Both are reachable in
practice when btintel_pcie_hw_error() is invoked from the HCI rx
path while another reset is being requested or is already in
flight.
1. data->reset_type was a plain shared field. The hw_error path
wrote it BEFORE the test_and_set_bit(RECOVERY_IN_PROGRESS)
guard inside btintel_pcie_reset(), so a second hw_error could
clobber the type chosen by an earlier in-flight request:
CPU0 (reset_work) CPU1 (hw_error #2)
dev_data->reset_type = PLDR
T2: read reset_type
dev_data->reset_type = FLR
reset() test_and_set sees 1
-> drops, but type already
clobbered
The hdev->reset callback (.reset = btintel_pcie_reset,
invoked via the sysfs reset attribute
/sys/class/bluetooth/hciX/reset and from hci_cmd_timeout())
compounded this by not writing reset_type at all -- it
inherited whatever value a previous hw_error / resume() had
left, which could be PLDR.
2. btintel_pcie_dump_debug_registers() was called unconditionally
at the top of hw_error(). When reset_work was already running
pci_try_reset_function(), the BT MMIO window can read all-1s
or trigger AER for the duration of the FLR, polluting the
debug dump with no useful information.
Refactor the reset path to make RECOVERY_IN_PROGRESS the sole
serializer for both the type write and the work scheduling:
- Replace btintel_pcie_reset(hdev) with
btintel_pcie_request_reset(data, type). The helper takes the
desired reset variant as a parameter and writes
data->reset_type only after winning test_and_set_bit(); losers
return without touching the field, so concurrent triggers can
no longer clobber an in-flight reset's type. reset_work()'s
read of reset_type is now ordered after the bit transition via
schedule_work()'s memory barrier.
- Add a thin btintel_pcie_hci_reset() wrapper for the
hdev->reset callback (invoked via the sysfs reset attribute
/sys/class/bluetooth/hciX/reset and from hci_cmd_timeout())
that always requests FLR explicitly, so these paths no longer
inherit stale state from prior error events.
- Add an early test_bit(RECOVERY_IN_PROGRESS) gate at the top of
hw_error() so dump_debug_registers() and the recovery-counter
bookkeeping are skipped when a reset is already in flight; the
authoritative test_and_set lives in request_reset() and races
cleanly against any caller that passes the optimistic check.
- Convert the two resume() reset sites (FREEZE/HIBERNATE and the
D0-error path) to request_reset(data, FLR), removing the
redundant manual reset_type writes.

Wiko Hi MateBook 14 Ryzen 200 laptops (DMI system-product-name
"MNCA-XX", board "M1060") are equipped with an RTL8852BE Wi-Fi/BT
combo chip (rtw89_8852be), whose Bluetooth radio enumerates as
1357:c123 instead of one of the already-supported 1358:c123 / 0bda:c123
identifiers, presumably due to OEM rebranding. Without a matching
entry it only matches the generic USB Bluetooth class fallback, so the
Realtek firmware/config (rtl8852btu_fw.bin / rtl8852btu_config.bin) is
never loaded and the adapter cannot discover or connect to any device,
even though hciconfig reports it as powered and scanning.
Device descriptor:
idVendor 0x1357
idProduct 0xc123
bcdDevice 0.00
iManufacturer 1 Realtek
iProduct 2 Bluetooth Radio
bDeviceClass 224 Wireless
bDeviceSubClass 1 Radio Frequency
bDeviceProtocol 1 Bluetooth
Adding the same BTUSB_REALTEK | BTUSB_WIDEBAND_SPEECH quirk already
used for 1358:c123 and 0bda:c123 fixes firmware loading and normal

btintel_pcie_coredump_worker() handled three unrelated jobs in one
work item: collect a DRAM trace coredump, read the hardware exception
event, and read the firmware-trigger event. The worker walked three
flag bits at runtime and each interrupt path mutated multiple bits
to communicate which sub-jobs the worker should run, which made the
ownership rules for those bits hard to reason about and entangled
the trigger reason with the in-progress accounting.
Replace the single combined worker with three single-purpose ones,
each owning exactly one flag:
coredump_work -> btintel_pcie_dump_traces()
guarded by COREDUMP_INPROGRESS
hwexp_work -> btintel_pcie_read_hwexp()
guarded by CORE_HALTED (already permanent until
re-probe; HWEXP_INPROGRESS is now redundant
and removed)
fwtrigger_work -> btintel_pcie_dump_fwtrigger_event()
guarded by FWTRIGGER_DUMP_INPROGRESS
All three workers are queued on a shared ordered workqueue (renamed
coredump_workqueue -> dump_workqueue) so a companion event reader
(hwexp/fwtrigger) and the coredump always run FIFO. Companion work
is queued before coredump_work so dmp_hdr.event_type/event_id are
populated by the time dump_traces() consumes them, preserving the
original ordering.
Introduce btintel_pcie_queue_coredump() to centralize the coredump
trigger contract: it is the single writer of COREDUMP_INPROGRESS and
of dmp_hdr.trigger_reason, sets both atomically against concurrent
triggers, and rolls back the bit if the workqueue is disabled
(reset/remove in progress) so a later trigger after re-probe can
succeed. All four trigger sites (HWEXP IRQ, FW-trigger IRQ,
devcoredump user trigger, resume() D0 error path) go through the
helper.
Per-work guard bits are now cleared at the tail of each worker
rather than in the middle of the combined worker, which closes a
subtle race where a duplicate IRQ could observe a cleared bit and
requeue while the previous pass was still finalizing
dev_coredumpv().
reset_work() and remove() now disable_work_sync() all three workers
and, on the FLR-failure path, enable_work() all three to keep their
disable counters balanced. The PLDR/FLR-success contract (re-probe
re-INIT_WORKs everything with counter 0) is preserved.
No functional change to the dump payloads; this is a pure
restructuring of the worker dispatch and its synchronization.

In nxp_serdev_probe(), if hci_register_dev() succeeds but ps_setup()
fails, the error path jumps to 'probe_fail' which only calls
hci_free_dev() and asserts the reset GPIO, but does NOT call
hci_unregister_dev() first.
This leaves the HCI device registered in the system with its backing
memory freed, leading to a use-after-free when userspace subsequently
accesses the device (e.g. via hciconfig or bluetoothd).
Fix by adding a 'probe_fail_unregister' label that calls
hci_unregister_dev() before falling through to the existing
'probe_fail' label. The original 'probe_fail' label is preserved
for the case where hci_register_dev() itself fails (device was
never registered, so no unregister is needed).
