+Subject: dmaengine: idxd: Let probe fail when workqueue cannot be enabled
+
+From: Reinette Chatre <reinette.chatre@intel.com>
+
+commit b51b75f0604f17c0f6f3b6f68f1a521a5cc6b04f upstream.
+
+The workqueue is enabled when the appropriate driver is loaded and
+disabled when the driver is removed. When the driver is removed it
+assumes that the workqueue was enabled successfully and proceeds to
+free allocations made during workqueue enabling.
+
+Failure during workqueue enabling does not prevent the driver from
+being loaded. This is because the error path within drv_enable_wq()
+returns success unless a second failure is encountered
+during the error path. By returning success it is possible to load
+the driver even if the workqueue cannot be enabled and
+allocations that do not exist are attempted to be freed during
+driver remove.
+
+Some examples of problematic flows:
+(a)
+
+ idxd_dmaengine_drv_probe() -> drv_enable_wq() -> idxd_wq_request_irq():
+ In above flow, if idxd_wq_request_irq() fails then
+ idxd_wq_unmap_portal() is called on error exit path, but
+ drv_enable_wq() returns 0 because idxd_wq_disable() succeeds. The
+ driver is thus loaded successfully.
+
+ idxd_dmaengine_drv_remove()->drv_disable_wq()->idxd_wq_unmap_portal()
+ Above flow on driver unload triggers the WARN in devm_iounmap() because
+ the device resource has already been removed during error path of
+ drv_enable_wq().
+
+(b)
+
+ idxd_dmaengine_drv_probe() -> drv_enable_wq() -> idxd_wq_request_irq():
+ In above flow, if idxd_wq_request_irq() fails then
+ idxd_wq_init_percpu_ref() is never called to initialize the percpu
+ counter, yet the driver loads successfully because drv_enable_wq()
+ returns 0.
+
+ idxd_dmaengine_drv_remove()->__idxd_wq_quiesce()->percpu_ref_kill():
+ Above flow on driver unload triggers a BUG when attempting to drop the
+ initial ref of the uninitialized percpu ref:
+ BUG: kernel NULL pointer dereference, address: 0000000000000010
+
+Fix the drv_enable_wq() error path by returning the original error that
+indicates failure of workqueue enabling. This ensures that the probe
+fails when an error is encountered and the driver remove paths are only
+attempted when the workqueue was enabled successfully.

+Subject: dmaengine: lgm: Move DT parsing after initialization
+
+From: Peter Harliman Liem <pliem@maxlinear.com>
+
+commit 96b3bb18f6cbe259ef4e0bed3135911b7e8d2af5 upstream.
+
+ldma_cfg_init() will parse DT to retrieve certain configs.
+However, that is called before ldma_dma_init_vXX(), which
+will make some initialization to channel configs. It will
+thus incorrectly overwrite certain configs that are declared
+in DT.
+
+To fix that, we move DT parsing after initialization.
+Function name is renamed to better represent what it does.

+
+From: Joshua Ashton <joshua@froggi.es>
+
+commit 973a9c810c785ac270a6d50d8cf862b0c1643a10 upstream.
+
+The YCC conversion matrix for RGB -> COLOR_SPACE_YCBCR2020_TYPE is
+missing the values for the fourth column of the matrix.
+
+The fourth column of the matrix is essentially just a value that is
+added given that the color is 3 components in size.
+These values are needed to bias the chroma from the [-1, 1] -> [0, 1]
+range.
+
+This fixes color being very green when using Gamescope HDR on HDMI
+output which prefers YCC 4:4:4.

+
+From: hongao <hongao@uniontech.com>
+
+commit 040625ab82ce6dca7772cb3867fe5c9eb279a344 upstream.
+
+[Why]
+Setting scaling does not correctly update CRTC state. As a result
+dc stream state's src (composition area) && dest (addressable area)
+was not calculated as expected. This causes set scaling doesn's work.
+
+[How]
+Correctly update CRTC state when setting scaling property.

+
+From: Khazhismel Kumykov <khazhy@chromium.org>
+
+commit a769b05eeed7accc4019a1ed9799dd72067f1ce8 upstream.
+
+We can get EFI variables without fetching the attribute, so we must
+allow for that in gsmi.
+
+commit 859748255b43 ("efi: pstore: Omit efivars caching EFI varstore
+access layer") added a new get_variable call with attr=NULL, which
+triggers panic in gsmi.

+From: Lino Sanfilippo <l.sanfilippo@kunbus.com>
+
+commit 4f39aca2360c82dccd2f5179d77e94aab665bea6 upstream.
+
+In RS485 mode the transmission of a high priority character fails since it
+is written to the data register before the transmitter is enabled. Fix this
+in pl011_tx_chars() by enabling RS485 transmission before writing the
+character.

+Subject: serial: atmel: fix incorrect baudrate setup
+
+From: Tobias Schramm <t.schramm@manjaro.org>
+
+commit 5bfdd3c654bd879bff50c2e85e42f85ae698b42f upstream.
+
+Commit ba47f97a18f2 ("serial: core: remove baud_rates when serial console
+setup") changed uart_set_options to select the correct baudrate
+configuration based on the absolute error between requested baudrate and
+available standard baudrate settings.
+Prior to that commit the baudrate was selected based on which predefined
+standard baudrate did not exceed the requested baudrate.
+This change of selection logic was never reflected in the atmel serial
+driver. Thus the comment left in the atmel serial driver is no longer
+accurate.
+Additionally the manual rounding up described in that comment and applied
+via (quot - 1) requests an incorrect baudrate. Since uart_set_options uses
+tty_termios_encode_baud_rate to determine the appropriate baudrate flags
+this can cause baudrate selection to fail entirely because
+tty_termios_encode_baud_rate will only select a baudrate if relative error
+between requested and selected baudrate does not exceed +/-2%.
+Fix that by requesting actual, exact baudrate used by the serial.
+

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>
+
+commit e8914b52e5b024e4af3d810a935fe0805eee8a36 upstream.
+
+A local variable sg is used to store scatterlist pointer in
+pch_dma_tx_complete(). The for loop doing Tx byte accounting before
+dma_unmap_sg() alters sg in its increment statement. Therefore, the
+pointer passed into dma_unmap_sg() won't match to the one given to
+dma_map_sg().
+
+To fix the problem, use priv->sg_tx_p directly in dma_unmap_sg()
+instead of the local variable.

+
+commit ce835dbd04d7b24f9fd50d9a9c59be46304aaa8a upstream.
+
+Hexadecimal addresses in device tree must be defined using lower case.
+There are some of them that are still in upper case. Change them all.

+Subject: tty: serial: qcom-geni-serial: fix slab-out-of-bounds on RX FIFO buffer
+
+From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
+
+commit b8caf69a6946e18ffebad49847e258f5b6d52ac2 upstream.
+
+Driver's probe allocates memory for RX FIFO (port->rx_fifo) based on
+default RX FIFO depth, e.g. 16. Later during serial startup the
+qcom_geni_serial_port_setup() updates the RX FIFO depth
+(port->rx_fifo_depth) to match real device capabilities, e.g. to 32.
+
+The RX UART handle code will read "port->rx_fifo_depth" number of words
+into "port->rx_fifo" buffer, thus exceeding the bounds. This can be
+observed in certain configurations with Qualcomm Bluetooth HCI UART
+device and KASAN:

+Subject: usb: cdns3: remove fetched trb from cache before dequeuing
+
+From: Pawel Laszczak <pawell@cadence.com>
+
+commit 1301c7b9f7efad2f11ef924e317c18ebd714fc9a upstream.
+
+After doorbell DMA fetches the TRB. If during dequeuing request
+driver changes NORMAL TRB to LINK TRB but doesn't delete it from
+controller cache then controller will handle cached TRB and packet
+can be lost.
+
+The example scenario for this issue looks like:
+1. queue request - set doorbell
+2. dequeue request
+3. send OUT data packet from host
+4. Device will accept this packet which is unexpected
+5. queue new request - set doorbell
+6. Device lost the expected packet.
+
+By setting DFLUSH controller clears DRDY bit and stop DMA transfer.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Maciej Żenczykowski <maze@google.com>
+
+commit c6ec929595c7443250b2a4faea988c62019d5cd2 upstream.
+
+In Google internal bug 265639009 we've received an (as yet) unreproducible
+crash report from an aarch64 GKI 5.10.149-android13 running device.
+
+AFAICT the source code is at:
+ https://android.googlesource.com/kernel/common/+/refs/tags/ASB-2022-12-05_13-5.10
+
+The call stack is:
+ ncm_close() -> ncm_notify() -> ncm_do_notify()
+with the crash at:
+ ncm_do_notify+0x98/0x270
+Code: 79000d0b b9000a6c f940012a f9400269 (b9405d4b)
+
+Which I believe disassembles to (I don't know ARM assembly, but it looks sane enough to me...):
+
+ // halfword (16-bit) store presumably to event->wLength (at offset 6 of struct usb_cdc_notification)
+ 0B 0D 00 79 strh w11, [x8, #6]
+
+ // word (32-bit) store presumably to req->Length (at offset 8 of struct usb_request)
+ 6C 0A 00 B9 str w12, [x19, #8]
+
+ // x10 (NULL) was read here from offset 0 of valid pointer x9
+ // IMHO we're reading 'cdev->gadget' and getting NULL
+ // gadget is indeed at offset 0 of struct usb_composite_dev
+ 2A 01 40 F9 ldr x10, [x9]
+
+ // loading req->buf pointer, which is at offset 0 of struct usb_request
+ 69 02 40 F9 ldr x9, [x19]
+
+ // x10 is null, crash, appears to be attempt to read cdev->gadget->max_speed
+ 4B 5D 40 B9 ldr w11, [x10, #0x5c]
+
+which seems to line up with ncm_do_notify() case NCM_NOTIFY_SPEED code fragment:
+
+ event->wLength = cpu_to_le16(8);
+ req->length = NCM_STATUS_BYTECOUNT;
+
+ /* SPEED_CHANGE data is up/down speeds in bits/sec */
+ data = req->buf + sizeof *event;
+ data[0] = cpu_to_le32(ncm_bitrate(cdev->gadget));
+
+My analysis of registers and NULL ptr deref crash offset
+ (Unable to handle kernel NULL pointer dereference at virtual address 000000000000005c)
+heavily suggests that the crash is due to 'cdev->gadget' being NULL when executing:
+ data[0] = cpu_to_le32(ncm_bitrate(cdev->gadget));
+which calls:
+ ncm_bitrate(NULL)
+which then calls:
+ gadget_is_superspeed(NULL)
+which reads
+ ((struct usb_gadget *)NULL)->max_speed
+and hits a panic.
+
+AFAICT, if I'm counting right, the offset of max_speed is indeed 0x5C.
+(remember there's a GKI KABI reservation of 16 bytes in struct work_struct)
+
+It's not at all clear to me how this is all supposed to work...
+but returning 0 seems much better than panic-ing...

+Subject: usb: gadget: g_webcam: Send color matching descriptor per frame
+
+From: Daniel Scally <dan.scally@ideasonboard.com>
+
+commit e95765e97d9cb93258a4840440d410fa6ff7e819 upstream.
+
+Currently the color matching descriptor is only sent across the wire
+a single time, following the descriptors for each format and frame.
+According to the UVC 1.5 Specification 3.9.2.6 ("Color Matching
+Descriptors"):
+
+"Only one instance is allowed for a given format and if present,
+the Color Matching descriptor shall be placed following the Video
+and Still Image Frame descriptors for that format".
+
+Add another reference to the color matching descriptor after the
+yuyv frames so that it's correctly transmitted for that format
+too.

+Subject: USB: gadgetfs: Fix race between mounting and unmounting
+
+From: Alan Stern <stern@rowland.harvard.edu>
+
+commit d18dcfe9860e842f394e37ba01ca9440ab2178f4 upstream.
+
+The syzbot fuzzer and Gerald Lee have identified a use-after-free bug
+in the gadgetfs driver, involving processes concurrently mounting and
+unmounting the gadgetfs filesystem. In particular, gadgetfs_fill_super()
+can race with gadgetfs_kill_sb(), causing the latter to deallocate
+the_device while the former is using it. The output from KASAN says,
+in part:
+

+
+commit 5d3d01ae15d2f37ed0325c99ab47ef0ae5d05f3c upstream.
+
+Commit ca07e1c1e4a6 ("drivers:usb:fsl:Make fsl ehci drv an independent
+driver module") changed DRV_NAME which was used for MODULE_ALIAS as well.
+Starting from this the module alias didn't match the platform device
+name created in fsl-mph-dr-of.c
+Change DRV_NAME to match the driver name for host mode in fsl-mph-dr-of.
+This is needed for module autoloading on ls1021a.

+Subject: usb-storage: apply IGNORE_UAS only for HIKSEMI MD202 on RTL9210
+
+From: Juhyung Park <qkrwngud825@gmail.com>
+
+commit dbd24ec17b85b45f4e823d1aa5607721920f2b05 upstream.
+
+The commit e00b488e813f ("usb-storage: Add Hiksemi USB3-FW to IGNORE_UAS")
+blacklists UAS for all of RTL9210 enclosures.
+
+The RTL9210 controller was advertised with UAS since its release back in
+2019 and was shipped with a lot of enclosure products with different
+firmware combinations.
+
+Blacklist UAS only for HIKSEMI MD202.
+
+This should hopefully be replaced with more robust method than just
+comparing strings. But with limited information [1] provided thus far
+(dmesg when the device is plugged in, which includes manufacturer and
+product, but no lsusb -v to compare against), this is the best we can do
+for now.

+Subject: usb: typec: tcpm: Fix altmode re-registration causes sysfs create fail
+
+From: ChiYuan Huang <cy_huang@richtek.com>
+
+commit 36f78477ac2c89e9a2eed4a31404a291a3450b5d upstream.
+
+There's the altmode re-registeration issue after data role
+swap (DR_SWAP).
+
+Comparing to USBPD 2.0, in USBPD 3.0, it loose the limit that only DFP
+can initiate the VDM command to get partner identity information.
+
+For a USBPD 3.0 UFP device, it may already get the identity information
+from its port partner before DR_SWAP. If DR_SWAP send or receive at the
+mean time, 'send_discover' flag will be raised again. It causes discover
+identify action restart while entering ready state. And after all
+discover actions are done, the 'tcpm_register_altmodes' will be called.
+If old altmode is not unregistered, this sysfs create fail can be found.
+
+In 'DR_SWAP_CHANGE_DR' state case, only DFP will unregister altmodes.
+For UFP, the original altmodes keep registered.
+
+This patch fix the logic that after DR_SWAP, 'tcpm_unregister_altmodes'
+must be called whatever the current data role is.
