cdc_ether: flag the Cinterion AHS8 modem by gemalto as WWAN

2018-04-24T07:32:04+00:00

[ Upstream commit 53765341ee821c0a0f1dec41adc89c9096ad694c ] The Cinterion AHS8 is a 3G device with one embedded WWAN interface using cdc_ether as a driver. The modem is controlled via AT commands through the exposed TTYs. AT+CGDCONT write command can be used to activate or deactivate a WWAN connection for a PDP context defined with the same command. UE supports one WWAN adapter. Signed-off-by: Bassem Boubaker Acked-by: Oliver Neukum Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

net: cdc_ether: fix divide by 0 on bad descriptors

2017-11-21T08:21:18+00:00

commit 2cb80187ba065d7decad7c6614e35e07aec8a974 upstream. Setting dev->hard_mtu to 0 will cause a divide error in usbnet_probe. Protect against devices with bogus CDC Ethernet functional descriptors by ignoring a zero wMaxSegmentSize. Signed-off-by: Bjørn Mork Acked-by: Oliver Neukum Signed-off-by: David S.

qmi_wwan/cdc_ether: add device ID for HP lt2523 (Novatel E371) WWAN card

2017-02-04T08:45:09+00:00

[ Upstream commit 5b9f57516337b523f7466a53939aaaea7b78141b ] Another rebranded Novatel E371. qmi_wwan should drive this device, while cdc_ether should ignore it. Even though the USB descriptors are plain CDC-ETHER that USB interface is a QMI interface.

cdc-acm: fix NULL pointer reference

2016-04-20T06:42:07+00:00

commit 29c6dd591bbd592472247441de9fa694acdabae8 upstream. The union descriptor must be checked. Its usage was conditional before the parser was introduced. This is important, because many RNDIS device, which also use the common parser, have bogus extra descriptors. Signed-off-by: Oliver Neukum Tested-by: Vasily Galkin Signed-off-by: David S.
