net: usb: rtl8150: set random MAC address when set_ethernet_addr() fails

2020-10-14T09:56:00+00:00

commit f45a4248ea4cc13ed50618ff066849f9587226b2 upstream. When get_registers() fails in set_ethernet_addr(),the uninitialized value of node_id gets copied over as the address. So, check the return value of get_registers(). If get_registers() executed successfully (i.e., it returns sizeof(node_id)), copy over the MAC address using ether_addr_copy() (instead of using memcpy()). Else, if get_registers() failed instead, a randomly generated MAC address is set as the MAC address instead.

rndis_host: increase sleep time in the query-response loop

2020-10-07T06:02:48+00:00

[ Upstream commit 4202c9fdf03d79dedaa94b2c4cf574f25793d669 ] Some WinCE devices face connectivity issues via the NDIS interface. They fail to register, resulting in -110 timeout errors and failures during the probe procedure. In this kind of WinCE devices, the Windows-side ndis driver needs quite more time to be loaded and configured, so that the linux rndis host queries to them fail to be responded correctly on time. More specifically, when INIT is called on the WinCE side - no other requests can be served by the Client and this results in a failed QUERY afterwards. The increase of the waiting time on the side of the linux rndis host in the command-response loop leaves the INIT process to complete and respond to a QUERY, which comes afterwards. The WinCE devices with this special "feature" in their ndis driver are satisfied by this fix. Signed-off-by: Olympia Giannou Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

net: usb: Fix uninit-was-stored issue in asix_read_phy_addr()

commit a092b7233f0e000cc6f2c71a49e2ecc6f917a5fc upstream. The buffer size is 2 Bytes and we expect to receive the same amount of data. But sometimes we receive less data and run into uninit-was-stored issue upon read. Hence modify the error check on the return value to match with the buffer size as a prevention.

r8152: Use MAC address from correct device tree node

2020-08-19T06:27:00+00:00

[ Upstream commit b9b40ee4db6cb186341b97bca4f0d7aa2a042a66 ] Query the USB device's device tree node when looking for a MAC address. The struct device embedded into the struct net_device does not have a device tree node attached at all. The reason why this went unnoticed is because the system where this was tested was one of the few development units that had its OTP programmed, as opposed to production systems where the MAC address is stored in a separate EEPROM and is passed via device tree by the firmware.

net: lan78xx: replace bogus endpoint lookup

2020-07-28T20:35:44+00:00

Drop the bogus endpoint-lookup helper which could end up accepting interfaces based on endpoints belonging to unrelated altsettings. Note that the returned bulk pipes and interrupt endpoint descriptor were never actually used. Instead the bulk-endpoint numbers are hardcoded to 1 and 2 (matching the specification), while the interrupt- endpoint descriptor was assumed to be the third descriptor created by USB core. Try to bring some order to this by dropping the bogus lookup helper and adding the missing endpoint sanity checks while keeping the interrupt- descriptor assumption for now.

net: lan78xx: fix transfer-buffer memory leak

net: lan78xx: add missing endpoint sanity check

2020-07-28T20:35:44+00:00

Add the missing endpoint sanity check to prevent a NULL-pointer dereference should a malicious device lack the expected endpoints. Note that the driver has a broken endpoint-lookup helper, lan78xx_get_endpoints(), which can end up accepting interfaces in an altsetting without endpoints as long as *some* altsetting has a bulk-in and a bulk-out endpoint.
