usb: rndis_host: Secure rndis_query check against int overflow

2023-01-12T11:00:40+00:00

[ Upstream commit c7dd13805f8b8fc1ce3b6d40f6aff47e66b72ad2 ] Variables off and len typed as uint32 in rndis_query function are controlled by incoming RNDIS response message thus their value may be manipulated. Setting off to a unexpectetly large value will cause the sum with len and 8 to overflow and pass the implemented validation step. Consequently the response pointer will be referring to a location past the expected buffer boundaries allowing information leakage e.g. via RNDIS_OID_802_3_PERMANENT_ADDRESS OID.

[ Upstream commit a487069e11b6527373f7c6f435d8998051d0b5d9 ] Add RmNet support for LARA-L6. LARA-L6 module can be configured (by AT interface) in three different USB modes: * Default mode (Vendor ID: 0x1546 Product ID: 0x1341) with 4 serial interfaces * RmNet mode (Vendor ID: 0x1546 Product ID: 0x1342) with 4 serial interfaces and 1 RmNet virtual network interface * CDC-ECM mode (Vendor ID: 0x1546 Product ID: 0x1343) with 4 serial interface and 1 CDC-ECM virtual network interface In RmNet mode LARA-L6 exposes the following interfaces: If 0: Diagnostic If 1: AT parser If 2: AT parser If 3: AT parset/alternative functions If 4: RMNET interface Signed-off-by: Davide Tronchin Acked-by: Bjørn Mork Signed-off-by: David S.

net/cdc_ncm: Fix multicast RX support for CDC NCM devices with ZLP

2022-12-02T16:43:08+00:00

[ Upstream commit 748064b54c99418f615aabff5755996cd9816969 ] ZLP for DisplayLink ethernet devices was enabled in 6.0: 266c0190aee3 ("net/cdc_ncm: Enable ZLP for DisplayLink ethernet devices"). The related driver_info should be the "same as cdc_ncm_info, but with FLAG_SEND_ZLP". However, set_rx_mode that enables handling multicast traffic was missing in the new cdc_ncm_zlp_info. usbnet_cdc_update_filter rx mode was introduced in linux 5.9 with: e10dcb1b6ba7 ("net: cdc_ncm: hook into set_rx_mode to admit multicast traffic") Without this hook, multicast, and then IPv6 SLAAC, is broken.

net: usb: smsc95xx: fix external PHY reset

[ Upstream commit 809ff97a677ff85dfb7ce2b63be261d1633dcf29 ] An external PHY needs settling time after power up or reset. In the bind() function an mdio bus is registered. If at this point the external PHY is still initialising, no valid PHY ID will be read and on phy_find_first() the bind() function will fail. If an external PHY is present, wait the maximum time specified in 802.3 45.2.7.1.1.

usbnet: Fix memory leak in usbnet_disconnect()

2022-09-26T18:23:22+00:00

Currently usbnet_disconnect() unanchors and frees all deferred URBs using usb_scuttle_anchored_urbs(), which does not free urb->context, causing a memory leak as reported by syzbot. Use a usb_get_from_anchor() while loop instead, similar to what we did in commit 19cfe912c37b ("Bluetooth: btusb: Fix memory leak in play_deferred"). Also free urb->sg.

r8152: add PID for the Lenovo OneLink+ Dock

2022-08-27T15:35:41+00:00

The Lenovo OneLink+ Dock contains an RTL8153 controller that behaves as a broken CDC device by default. Add the custom Lenovo PID to the r8152 driver to support it properly. Also, systems compatible with this dock provide a BIOS option to enable MAC address passthrough (as per Lenovo document "ThinkPad Docking Solutions 2017"). Add the custom PID to the MAC passthrough list too. Tested on a ThinkPad 13 1st gen with the expected results: passthrough disabled: Invalid header when reading pass-thru MAC addr passthrough enabled: Using pass-thru MAC addr XX:XX:XX:XX:XX:XX Signed-off-by: Jean-Francois Le Fillatre Signed-off-by: David S.
