[PATCH 4/5] media: ipu-bridge: Add DMI quirk for Dell XPS laptops with upside down sensors

by Hans de Goede

The Dell XPS 13 9350 and XPS 16 9640 both have an upside-down mounted OV02C10 sensor. This rotation of 180° is reported in neither the SSDB nor the _PLD for the sensor (both report a rotation of 0°). Add a DMI quirk mechanism for upside-down sensors and add 2 initial entries to the DMI quirk list for these 2 laptops. Note the OV02C10 driver was originally developed on a XPS 16 9640 which resulted in inverted vflip + hflip settings making it look like the sensor was upright on the XPS 16 9640 and upside down elsewhere this has been fixed in commit 69fe27173396 ("media: ov02c10: Fix default vertical flip"). This makes this commit a regression fix since now the video is upside down on these Dell XPS models where it was not before.

[PATCH v3] net/handshake: restore destructor on submit failure

handshake_req_submit() replaces sk->sk_destruct but never restores it when submission fails before the request is hashed. handshake_sk_destruct() then returns early and the original destructor never runs, leaking the socket.

[PATCH net 2/2] can: gs_usb: gs_can_open(): fix error handling

by Marc Kleine-Budde

Commit 2603be9e8167 ("can: gs_usb: gs_can_open(): improve error handling") added missing error handling to the gs_can_open() function. The driver uses 2 USB anchors to track the allocated URBs: the TX URBs in struct gs_can::tx_submitted for each netdev and the RX URBs in struct gs_usb::rx_submitted for the USB device. gs_can_open() allocates the RX URBs, while TX URBs are allocated during gs_can_start_xmit(). The cleanup in gs_can_open() kills all anchored dev->tx_submitted URBs (which is not necessary since the netdev is not yet registered), but misses the parent->rx_submitted URBs. Fix the problem by killing the rx_submitted instead of the tx_submitted.

[PATCH v2] net: nfc: nci: Fix parameter validation for packet data

by Michael Thalmeier

Since commit 9c328f54741b ("net: nfc: nci: Add parameter validation for packet data") communication with nci nfc chips is not working any more. The mentioned commit tries to fix access of uninitialized data, but failed to understand that in some cases the data packet is of variable length and can therefore not be compared to the maximum packet length given by the sizeof(struct). For these cases it is only possible to check for minimum packet length.
