usbnet: ipheth: fix connectivity with iOS 14

2020-12-08T09:18:52+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

2020-10-14T08:31:26+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

2020-10-07T06:00:06+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.

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

2020-09-09T17:04:32+00:00

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.
