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.

usbnet: cleanup after bind() in probe()

2016-04-20T06:41:59+00:00

[ Upstream commit 1666984c8625b3db19a9abc298931d35ab7bc64b ] In case bind() works, but a later error forces bailing in probe() in error cases work and a timer may be scheduled. They must be killed. This fixes an error case related to the double free reported in http://www.spinics.net/lists/netdev/msg367669.html and needs to go on top of Linus' fix to cdc-ncm.

cdc_ncm: toggle altsetting to force reset before setup

2016-04-20T06:41:59+00:00

[ Upstream commit 48906f62c96cc2cd35753e59310cb70eb08cc6a5 ] Some devices will silently fail setup unless they are reset first. This is necessary even if the data interface is already in altsetting 0, which it will be when the device is probed for the first time. Briefly toggling the altsetting forces a function reset regardless of the initial state. This fixes a setup problem observed on a number of Huawei devices, appearing to operate in NTB-32 mode even if we explicitly set them to NTB-16 mode. Signed-off-by: Bjørn Mork Signed-off-by: David S.

r8152: add reset_resume function

2016-01-05T03:02:08+00:00

When the reset_resume() is called, the flag of SELECTIVE_SUSPEND should be cleared and reinitialize the device, whether the SELECTIVE_SUSPEND is set or not. If reset_resume() is called, it means the power supply is cut or the device is reset. That is, the device wouldn't be in runtime suspend state and the reinitialization is necessary.

net: cdc_ncm: avoid changing RX/TX buffers on MTU changes

2015-12-24T03:52:08+00:00

NCM buffer sizes are negotiated with the device independently of the network device MTU. The RX buffers are allocated by the usbnet framework based on the rx_urb_size value set by cdc_ncm. A single RX buffer can hold a number of MTU sized packets. The default usbnet change_mtu ndo only modifies rx_urb_size if it is equal to hard_mtu. And the cdc_ncm driver will set rx_urb_size and hard_mtu independently of each other, based on dwNtbInMaxSize and dwNtbOutMaxSize respectively. It was therefore assumed that usbnet_change_mtu() would never touch rx_urb_size. This failed to consider the case where dwNtbInMaxSize and dwNtbOutMaxSize happens to be equal. Fix by implementing an NCM specific change_mtu ndo, modifying the netdev MTU without touching the buffer size settings. Signed-off-by: Bjørn Mork Signed-off-by: David S. Miller
