2021-08-05drm/i915: fix i915_globals_exit() section mismatch errorRandy Dunlap1-1/+1
Fix modpost Section mismatch error in i915_globals_exit(). Since both an __init function and an __exit function can call i915_globals_exit(), any function that i915_globals_exit() calls should not be marked as __init or __exit. I.e., it needs to be available for either of them. WARNING: modpost: vmlinux.o(.text+0x8b796a): Section mismatch in reference from the function i915_globals_exit() to the function .exit.text:__i915_globals_flush() The function i915_globals_exit() references a function in an exit section. Often the function __i915_globals_flush() has valid usage outside the exit section and the fix is to remove the __exit annotation of __i915_globals_flush. ERROR: modpost: Section mismatches detected. Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.

The register offset for SFC_DONE was missing a '0' at the end, causing us to read from a non-existent register address. We only use this register in error state dumps so the mistake hasn't caused any real problems, but fixing it will hopefully make the error state dumps a bit more useful for debugging.

2021-07-30can: esd_usb2: fix memory leakPavel Skripkin1-1/+15
In esd_usb2_setup_rx_urbs() MAX_RX_URBS coherent buffers are allocated and there is nothing, that frees them: 1) In callback function the urb is resubmitted and that's all 2) In disconnect function urbs are simply killed, but URB_FREE_BUFFER is not set (see esd_usb2_setup_rx_urbs) and this flag cannot be used with coherent buffers. So, all allocated buffers should be freed with usb_free_coherent() explicitly. Side note: This code looks like a copy-paste of other can drivers. The same patch was applied to mcba_usb driver and it works nice with real hardware. There is no change in functionality, only clean-up code for coherent buffers.

2021-07-30can: mcba_usb_start(): add missing urb->transfer_dma initializationPavel Skripkin1-0/+2
Yasushi reported, that his Microchip CAN Analyzer stopped working since commit 91c02557174b ("can: mcba_usb: fix memory leak in mcba_usb"). The problem was in missing urb->transfer_dma initialization. In my previous patch to this driver I refactored mcba_usb_start() code to avoid leaking usb coherent buffers. To archive it, I passed local stack variable to usb_alloc_coherent() and then saved it to private array to correctly free all coherent buffers on ->close() call. But I forgot to initialize urb->transfer_dma with variable passed to usb_alloc_coherent(). All of this was causing device to not work, since dma addr 0 is not valid and following log can be found on bug report page, which points exactly to problem described above. | DMAR: [DMA Write] Request device [00:14.0] PASID ffffffff fault addr 0 [fault reason 05] PTE Write access is not set Fixes: 91c02557174b ("can: mcba_usb: fix memory leak in mcba_usb") Link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=990850 Link: https://lore.kernel.org/r/20210725103630.23864-1-paskripkin@gmail.com Cc: linux-stable <stable@vger.kernel.org> Reported-by: Yasushi SHOJI <yasushi.shoji@gmail.com> Signed-off-by: Pavel Skripkin <paskripkin@gmail.com> Tested-by: Yasushi SHOJI <yashi@spacecubics.com> [mkl: fixed typos in commit message - thanks Yasushi SHOJI] Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>

2021-07-29HID: ft260: fix device removal due to USB disconnectMichael Zaidman1-16/+7
This commit fixes a functional regression introduced by the commit 82f09a637dd3 ("HID: ft260: improve error handling of ft260_hid_feature_report_get()") when upon USB disconnect, the FTDI FT260 i2c device is still available within the /dev folder. In my company's product, where the host USB to FT260 USB connection is hard-wired in the PCB, the issue is not reproducible. To reproduce it, I used the VirtualBox Ubuntu 20.04 VM and the UMFT260EV1A development module for the FTDI FT260 chip: Plug the UMFT260EV1A module into a USB port and attach it to VM. The VM shows 2 i2c devices under the /dev: michael@michael-VirtualBox:~$ ls /dev/i2c-* /dev/i2c-0 /dev/i2c-1 The i2c-0 is not related to the FTDI FT260: michael@michael-VirtualBox:~$ cat /sys/bus/i2c/devices/i2c-0/name SMBus PIIX4 adapter at 4100 The i2c-1 is created by hid-ft260.ko: michael@michael-VirtualBox:~$ cat /sys/bus/i2c/devices/i2c-1/name FT260 usb-i2c bridge on hidraw1 Now, detach the FTDI FT260 USB device from VM. We expect the /dev/i2c-1 to disappear, but it's still here: michael@michael-VirtualBox:~$ ls /dev/i2c-* /dev/i2c-0 /dev/i2c-1 And the kernel log shows: [ +0.001202] usb 2-2: USB disconnect, device number 3 [ +0.000109] ft260 0003:0403:6030.0002: failed to retrieve system status [ +0.000316] ft260 0003:0403:6030.0003: failed to retrieve system status It happens because the commit 82f09a637dd3 changed the ft260_get_system_config() return logic. This caused the ft260_is_interface_enabled() to exit with error upon the FT260 device USB disconnect, which in turn, aborted the ft260_remove() before deleting the FT260 i2c device and cleaning its sysfs stuff. This commit restores the FT260 USB removal functionality and improves the ft260_is_interface_enabled() code to handle correctly all chip modes defined by the device interface configuration pins DCNF0 and DCNF1.

2021-07-28ACPI: DPTF: Fix reading of attributesSrinivas Pandruvada1-8/+43
The current assumption that methods to read PCH FIVR attributes will return integer, is not correct. There is no good way to return integer as negative numbers are also valid. These read methods return a package of integers. The first integer returns status, which is 0 on success and any other value for failure. When the returned status is zero, then the second integer returns the actual value. This change fixes this issue by replacing acpi_evaluate_integer() with acpi_evaluate_object() and use acpi_extract_package() to extract results.

Commit 670e90924bfe ("HID: wacom: support named keys on older devices") added support for sending named events from the soft buttons on the 24HDT and 27QHDT. In the process, however, it inadvertantly disabled the touchscreen of the 24HDT and 27QHDT by default. The `wacom_set_shared_values` function would normally enable touch by default but because it checks the state of the non-shared `has_mute_touch_switch` flag and `wacom_setup_touch_input_capabilities` sets the state of the /shared/ version, touch ends up being disabled by default. This patch sets the non-shared flag, letting `wacom_set_shared_values` take care of copying the value over to the shared version and setting the default touch state to "on".

2021-07-27net/mlx5e: Fix nullptr in mlx5e_hairpin_get_mdev()Dima Chumak1-2/+31
The result of __dev_get_by_index() is not checked for NULL and then gets dereferenced immediately. Also, __dev_get_by_index() must be called while holding either RTNL lock or @dev_base_lock, which isn't satisfied by mlx5e_hairpin_get_mdev() or its callers. This makes the underlying hlist_for_each_entry() loop not safe, and can have adverse effects in itself. Fix by using dev_get_by_index() and handling nullptr return value when ifindex device is not found. Update mlx5e_hairpin_get_mdev() callers to check for possible PTR_ERR() result.

2021-07-27net/mlx5e: RX, Avoid possible data corruption when relaxed ordering and LRO ↵Tariq Toukan1-1/+10
combined When HW aggregates packets for an LRO session, it writes the payload of two consecutive packets of a flow contiguously, so that they usually share a cacheline. The first byte of a packet's payload is written immediately after the last byte of the preceding packet. In this flow, there are two consecutive write requests to the shared cacheline: 1. Regular write for the earlier packet. 2. Read-modify-write for the following packet. In case of relaxed-ordering on, these two writes might be re-ordered. Using the end padding optimization (to avoid partial write for the last cacheline of a packet) becomes problematic if the two writes occur out-of-order, as the padding would overwrite payload that belongs to the following packet, causing data corruption. Avoid this by disabling the end padding optimization when both LRO and relaxed-ordering are enabled.
