usbnet: ipheth: fix connectivity with iOS 14

2020-12-08T09:42:00+00:00

[ Upstream commit f33d9e2b48a34e1558b67a473a1fc1d6e793f93c ] Starting with iOS 14 released in September 2020, connectivity using the personal hotspot USB tethering function of iOS devices is broken. Communication between the host and the device (for example ICMP traffic or DNS resolution using the DNS service running in the device itself) works fine, but communication to endpoints further away doesn't work. Investigation on the matter shows that no UDP and ICMP traffic from the tethered host is reaching the Internet at all. For TCP traffic there are exchanges between tethered host and server but packets are modified in transit leading to impossible communication. After some trials Matti Vuorela discovered that reducing the URB buffer size by two bytes restored the previous behavior. While a better solution might exist to fix the issue, since the protocol is not publicly documented and considering the small size of the fix, let's do that.

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

2020-10-06T13:10:21+00:00

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.

net: usb: pegasus: Proper error handing when setting pegasus' MAC address

2020-10-02T22:18:42+00:00

v2: If reading the MAC address from eeprom fail don't throw an error, use randomly generated MAC instead. Either way the adapter will soldier on and the return type of set_ethernet_addr() can be reverted to void. v1: Fix a bug in set_ethernet_addr() which does not take into account possible errors (or partial reads) returned by its helpers. This can potentially lead to writing random data into device's MAC address registers. Signed-off-by: Petko Manolov Signed-off-by: David S. Miller

rndis_host: increase sleep time in the query-response loop

2020-09-14T21:39:59+00:00

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
