usb: dwc3: Properly handle processing of pending events
If dwc3 is runtime suspended we defer processing the event buffer
until resume, by setting the pending_events flag. Set this flag before
triggering resume to avoid race with the runtime resume callback.
While handling the pending events, in addition to checking the event
buffer we also need to process it. Handle this by explicitly calling
dwc3_thread_interrupt(). Also balance the runtime pm get() operation
that triggered this processing.

usb-storage: alauda: Fix uninit-value in alauda_check_media()
Syzbot got KMSAN to complain about access to an uninitialized value in
the alauda subdriver of usb-storage:
BUG: KMSAN: uninit-value in alauda_transport+0x462/0x57f0
drivers/usb/storage/alauda.c:1137
CPU: 0 PID: 12279 Comm: usb-storage Not tainted 5.3.0-rc7+ #0
Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS
Google 01/01/2011
Call Trace:

alauda_check_media+0x344/0x3310 drivers/usb/storage/alauda.c:460
The problem is that alauda_check_media() doesn't verify that its USB
transfer succeeded before trying to use the received data. What
should happen if the transfer fails isn't entirely clear, but a
reasonably conservative approach is to pretend that no media is
present.
A similar problem exists in a usb_stor_dbg() call in
alauda_get_media_status(). In this case, when an error occurs the
call is redundant, because usb_stor_ctrl_transfer() already will print
a debugging message.
Finally, unrelated to the uninitialized memory access, is the fact
that alauda_check_media() performs DMA to a buffer on the stack.
Fortunately usb-storage provides a general purpose DMA-able buffer for
uses like this. We'll use it instead.

usb: common: usb-conn-gpio: Prevent bailing out if initial role is none
Currently if we bootup a device without cable connected, then
usb-conn-gpio won't call set_role() because last_role is same
as current role. This happens since last_role gets initialised
to zero during the probe.
To avoid this, add a new flag initial_detection into struct
usb_conn_info, which prevents bailing out during initial
detection.

USB: Gadget: core: Help prevent panic during UVC unconfigure
Avichal Rakesh reported a kernel panic that occurred when the UVC
gadget driver was removed from a gadget's configuration. The panic
involves a somewhat complicated interaction between the kernel driver
and a userspace component (as described in the Link tag below), but
the analysis did make one thing clear: The Gadget core should
accomodate gadget drivers calling usb_gadget_deactivate() as part of
their unbind procedure.
Currently this doesn't work. gadget_unbind_driver() calls
driver->unbind() while holding the udc->connect_lock mutex, and
usb_gadget_deactivate() attempts to acquire that mutex, which will
result in a deadlock.
The simple fix is for gadget_unbind_driver() to release the mutex when
invoking the ->unbind() callback. There is no particular reason for
it to be holding the mutex at that time, and the mutex isn't held
while the ->bind() callback is invoked. So we'll drop the mutex
before performing the unbind callback and reacquire it afterward.
We'll also add a couple of comments to usb_gadget_activate() and
usb_gadget_deactivate(). Because they run in process context they
must not be called from a gadget driver's ->disconnect() callback,
which (according to the kerneldoc for struct usb_gadget_driver in
include/linux/usb/gadget.h) may run in interrupt context. This may
help prevent similar bugs from arising in the future.

usb: typec: altmodes/displayport: Signal hpd when configuring pin assignment
When connecting to some DisplayPort partners, the initial status update
after entering DisplayPort Alt Mode notifies that the DFP_D/UFP_D is not in
the connected state. This leads to sending a configure message that keeps
the device in USB mode. The port partner then sets DFP_D/UFP_D to the
connected state and HPD to high in the same Attention message. Currently,
the HPD signal is dropped in order to handle configuration.
This patch saves changes to the HPD signal when the device chooses to
configure during dp_altmode_status_update, and invokes sysfs_notify if
necessary for HPD after configuring.

USB: quirks: add quirk for Focusrite Scarlett
The Focusrite Scarlett audio device does not behave correctly during
resumes. Below is what happens during every resume (captured with
Beagle 5000):
<Suspend>
<Resume>
<Reset>/<Chirp J>/<Tiny J>
<Reset/Target disconnected>
<High Speed>
The Scarlett disconnects and is enumerated again.
However from time to time it drops completely off the USB bus during
resume. Below is captured occurrence of such an event:
<Suspend>
<Resume>
<Reset>/<Chirp J>/<Tiny J>
<Reset>/<Chirp K>/<Tiny K>
<High Speed>
<Corrupted packet>
<Reset/Target disconnected>
To fix the condition a user has to unplug and plug the device again.
With USB_QUIRK_RESET_RESUME applied ("usbcore.quirks=1235:8211:b")
for the Scarlett audio device the issue still reproduces.
Applying USB_QUIRK_DISCONNECT_SUSPEND ("usbcore.quirks=1235:8211:m")
fixed the issue and the Scarlett audio device didn't drop off the USB
bus for ~5000 suspend/resume cycles where originally issue reproduced in
~100 or less suspend/resume cycles.

These are mostly minor cleanups and bugfixes that address harmless problems. The largest branch is a conversion of the omap platform to use GPIO descriptors throughout the tree, for any devices that are not fully converted to devicetree. The Samsung Exynos platform gains back support for the Exynos4212 chip that was previously unused and removed but is now used for the Samsung Galaxy Tab3. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmScsH8ACgkQYKtH/8kJ UicTOhAAxQB1zySNJ4vOwTnV9Mrey+b/1RvjKDwZAa3uuP6vgpPjAjqVxlRxl+TM SWal+0zzj+vrFTkTl0niT+DzMFOEnLqhBd7smN8YKmC+hD3t9g5Dos7Q/IsUVlrT SnXDmit+eSI2QXFeO1OM0LdmniLDcKydsQ8o4beKF6YaJRGYACNSmtIjB3KvWccv 3cQXoaqN5rFoQxbLiGVINVyDU3Qpie2m8RqUcVWSmva46UM2yDAUWXwFNxcP8jXp WjL+NaiH7Ea/pzPcn3895u5ybIOZSylxLGRzL1ktewJqczUKf701qVZbf6enZp99 SbEQQh4DKm4DkpQ/JdPoO9x3InORAGUQ1p0Ssa92rKuiEVSXsQUeO3BNAYGfvpy3 o3QElSp6hlDWOHk9KawHzY3lfMsvKnTckFQDZxMbvC0+tQj6cDIM/qWo74CdZ07S UxVa1C9L2Lerv6IAG3v2meI9HjBn7DInWjfOAOxj2gX/ryIrdX9lO0692n6nVYca szH3CANjwPCPrtjAE2RXPjLTK+6nmQDavcEVEiG1SoGTplLh7RZgeQXV+5iIaOLp Nc8MDddR656kPBEprgoEugGZuLjsY2IGaLj+FNGriOEBKo5jpfEFeRQ2GPKxoyWR OHeWtxcFtBc2SnfVOtdMQ/X3UZTd4vlJYbNffiL+2NSM0iMBbHs= =z6FU -----END PGP SIGNATURE----- Merge tag 'soc-arm-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC updates from Arnd Bergmann: "These are mostly minor cleanups and bugfixes that address harmless problems.

Merge tag 'gpio-updates-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"We have two new drivers, some improvements to the core code, lots of
different updates to existing GPIO drivers and some dt-bindings on
top.
There's nothing controversial in here and almost everything has been
in next for more than a week (95% a lot longer than this). The only
thing that has spent less time in next is a new driver so no risk of
regressions.
The single merge pulls in changes that remove all usage of global GPIO
numbers from arch/arm/mach-omap.

- remove unused symbols

There are situations during the xhci_resume() sequence, which allows for re-initializing of the XHCI HC. However, in case the HCD is being removed, these operations may not be needed. Set the removal state before issuing the runtime PM get on the XHCI device, so that the XHCI resume routine will know when to bypass the re-init logic.

usb: host: xhci: Do not re-initialize the XHCI HC if being removed
During XHCI resume, if there was a host controller error detected the routine will attempt to re-initialize the XHCI HC, so that it can return back to an operational state. If the XHCI host controller is being removed, this sequence would be already handled within the XHCI halt path, leading to a duplicate set of reg ops/calls. In addition, since the XHCI bus is being removed, the overhead added in restarting the HCD is unnecessary. Check for the XHC state before setting the reinit_xhc parameter, which is responsible for triggering the restart.

usb: typec: nb7vpq904m: fix CONFIG_DRM dependency
With the following config set:
CONFIG_DRM=m
CONFIG_DRM_PANEL=y
CONFIG_DRM_BRIDGE=y
CONFIG_DRM_PANEL_BRIDGE=y
CONFIG_TYPEC_MUX_NB7VPQ904M=y
vmlinux fails on the following symbols:
ld.lld: error: undefined symbol: devm_drm_bridge_add
ld.lld: error: undefined symbol: devm_drm_of_get_bridge
Add dependendy on DRM || DRM=no since CONFIG_DRM dependency is optional
and guarded by:
IS_ENABLED(CONFIG_OF) && IS_ENABLED(CONFIG_DRM_PANEL_BRIDGE)
in the drive.
Also add "select DRM_PANEL_BRIDGE if DRM" to clarify DRM_PANEL_BRIDGE
is required if CONFIG_DRM is enabled.

usbip: usbip_host: Replace strlcpy with strscpy
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). Direct replacement is safe here since return value of -errno is used to check for truncation instead of sizeof(dest).

usb: dwc3: gadget: Propagate core init errors to UDC during pullup
In scenarios where pullup relies on resume (get sync) to initialize
the controller and set the run stop bit, then core_init is followed by
gadget_resume which will eventually set run stop bit.
But in cases where the core_init fails, the return value is not sent
back to udc appropriately. So according to UDC the controller has
started but in reality we never set the run stop bit.
On systems like Android, there are uevents sent to HAL depending on
whether the configfs_bind / configfs_disconnect were invoked. In the
above mentioned scnenario, if the core init fails, the run stop won't
be set and the cable plug-out won't result in generation of any
disconnect event and userspace would never get any uevent regarding
cable plug out and we never call pullup(0) again. Furthermore none of
the next Plug-In/Plug-Out's would be known to configfs.
Return back the appropriate result to UDC to let the userspace/
configfs know that the pullup failed so they can take appropriate
action.

USB: serial: option: add LARA-R6 01B PIDs
The new LARA-R6 product variant identified by the "01B" string can be configured (by AT interface) in three different USB modes: * Default mode (Vendor ID: 0x1546 Product ID: 0x1311) with 4 serial interfaces * RmNet mode (Vendor ID: 0x1546 Product ID: 0x1312) with 4 serial interfaces and 1 RmNet virtual network interface * CDC-ECM mode (Vendor ID: 0x1546 Product ID: 0x1313) with 4 serial interface and 1 CDC-ECM virtual network interface The first 4 interfaces of all the 3 USB configurations (default, RmNet, CDC-ECM) are the same. In default mode LARA-R6 01B exposes the following interfaces: If 0: Diagnostic If 1: AT parser If 2: AT parser If 3: AT parser/alternative functions In RmNet mode LARA-R6 01B exposes the following interfaces: If 0: Diagnostic If 1: AT parser If 2: AT parser If 3: AT parser/alternative functions If 4: RMNET interface In CDC-ECM mode LARA-R6 01B exposes the following interfaces: If 0: Diagnostic If 1: AT parser If 2: AT parser If 3: AT parser/alternative functions If 4: CDC-ECM interface Signed-off-by: Davide Tronchin <davide.tronchin.94@gmail.com> Link: https://lore.kernel.org/r/20230622092921.12651-1-davide.tronchin.94@gmail.com Cc: stable@vger.kernel.org Signed-off-by: Johan Hovold <johan@kernel.org> |
