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

by caoping

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. Restore sk_destruct on the error path.

[PATCH] drm/xe/bo: Don't include the CCS metadata in the dma-buf sg-table

[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.

[PATCH 6.17 54/60] iio: adc: ad4080: fix chip identification

by Greg Kroah-Hartman

6.17-stable review patch. If anyone has any objections, please let me know. ------------------ From: Antoniu Miclaus <antoniu.miclaus(a)analog.com> commit b66cddc8be7278fd14650ff9182f3794397f8b31 upstream. Fix AD4080 chip identification by using the correct 16-bit product ID (0x0050) instead of GENMASK(2, 0). Update the chip reading logic to use regmap_bulk_read to read both PRODUCT_ID_L and PRODUCT_ID_H registers and combine them into a 16-bit value. The original implementation was incorrectly reading only 3 bits, which would not correctly identify the AD4080 chip.
