2018-01-10caif_usb: use strlcpy() instead of strncpy()Xiongfeng Wang
gcc-8 reports net/caif/caif_usb.c: In function 'cfusbl_device_notify': ./include/linux/string.h:245:9: warning: '__builtin_strncpy' output may be truncated copying 15 bytes from a string of length 15 [-Wstringop-truncation] The compiler require that the input param 'len' of strncpy() should be greater than the length of the src string, so that '\0' is copied as well. We can just use strlcpy() to avoid this warning. Signed-off-by: Xiongfeng Wang <xiongfeng.wang@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-05-28net: pass info struct via netdevice notifierJiri Pirko
So far, only net_device * could be passed along with netdevice notifier event. This patch provides a possibility to pass custom structure able to provide info that event listener needs to know.

2012-12-09caif_usb: Make the driver name check more efficientBen Hutchings
Use the device model to get just the name, rather than using the ethtool API to get all driver information. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-12-09caif_usb: Check driver name before reading driver state in netdev notifierBen Hutchings
In cfusbl_device_notify(), the usbnet and usbdev variables are initialised before the driver name has been checked. In case the device's driver is not cdc_ncm, this may result in reading beyond the end of the netdev private area. Move the initialisation below the driver name check.

2011-12-05caif: Add support for CAIF over CDC NCM USB interfacesjur.brandeland@stericsson.com
NCM 1.0 does not support anything but Ethernet framing, hence CAIF payload will be put into Ethernet frames. Discovery is based on fixed USB vendor 0x04cc (ST-Ericsson), product-id 0x230f (NCM). In this variant only CAIF payload is sent over the NCM interface. The CAIF stack (cfusbl.c) will when USB interface register first check if we got a CDC NCM USB interface with the right VID, PID. It will then read the device's Ethernet address and create a 'template' Ethernet TX header, using a broadcast address as the destination address, and EthType 0x88b5 (802.1 Local Experimental - vendor specific). A protocol handler for 0x88b5 is setup for reception of CAIF frames from the CDC NCM USB interface. Signed-off-by: Sjur Brændeland <sjur.brandeland@stericsson.com> Signed-off-by: David S.
