Subject: [PATCH net 0/8] pull-request: can 2025-11-26

Hello netdev-team,

this is a pull request of 8 patches for net/main.

Seungjin Bae provides a patch for the kvaser_usb driver to fix a
potential infinite loop in the USB data stream command parser.

Thomas Mühlbacher's patch for the sja1000 driver IRQ handler's max
loop handling, that might lead to unhandled interrupts.

3 patches by me for the gs_usb driver fix handling of failed transmit
URBs and add checking of the actual length of received URBs before
accessing the data.

The next patch is by me and is a port of Thomas Mühlbacher's patch
(fix IRQ handler's max loop handling, that might lead to unhandled
interrupts.) to the sun4i_can driver.

Biju Das provides a patch for the rcar_canfd driver to fix the CAN-FD
mode setting.

The last patch is by Shaurya Rane for the em_canid filter to ensure
that the complete CAN frame is present in the linear data buffer
before accessing it.

regards,
Marc
