2011-01-14USB CDC NCM: Don't deref NULL in cdc_ncm_rx_fixup() and don't use ↵Jesper Juhl
uninitialized variable. skb_clone() dynamically allocates memory and may fail. If it does it returns NULL. This means we'll dereference a NULL pointer in drivers/net/usb/cdc_ncm.c::cdc_ncm_rx_fixup(). As far as I can tell, the proper way to deal with this is simply to goto the error label. Furthermore gcc complains that 'skb' may be used uninitialized: drivers/net/usb/cdc_ncm.c: In function ‘cdc_ncm_rx_fixup’: drivers/net/usb/cdc_ncm.c:922:18: warning: ‘skb’ may be used uninitialized in this function and I believe it is right. On the line where we pr_debug("invalid frame detected (ignored)" ... we are using the local variable 'skb' but nothing has ever been assigned to that variable yet. I believe the correct fix for that is to use 'skb_in' instead. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-12-12drivers/net: don't use flush_scheduled_work()Tejun Heo
flush_scheduled_work() is on its way out. This patch contains simple conversions to replace flush_scheduled_work() usage with direct cancels and flushes. Directly cancel the used works on driver detach and flush them in other cases. The conversions are mostly straight forward and the only dangers are, * Forgetting to cancel/flush one or more used works. * Cancelling when a work should be flushed (ie. the work must be executed once scheduled whether the driver is detaching or not). I've gone over the changes multiple times but it would be much appreciated if you can review with the above points in mind. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: "David S.

2010-10-21smsc95xx: generate random MAC address once, not every ifupBernard Blackham
The smsc95xx driver currently generates a new random MAC address every time the interface is brought up. This makes it impossible to override using the standard `ifconfig hw ether` approach. Past patches tried to make the MAC address a module parameter or base it off the die ID, but it seems to me much simpler (and hopefully less controversial) to stick with the current random generation scheme, but allow the user to change the address. This patch does exactly that - it moves the random address generation from smsc95xx_reset() into smsc95xx_bind(), so that it is done once on module load, not on every ifup. The user can then override this using the standard mechanisms. Applies against 2.6.35 and linux-2.6 head. Signed-off-by: Bernard Blackham <b-omap@largestprime.net> Signed-off-by: David S.

2010-09-10ipheth: remove incorrect devtype to WWANDan Williams
The 'wwan' devtype is meant for devices that require preconfiguration and *every* time setup before the ethernet interface can be used, like cellular modems which require a series of setup commands on serial ports or other mechanisms before the ethernet interface will handle packets. As ipheth only requires one-per-hotplug pairing setup with no preconfiguration (like APN, phone #, etc) and the network interface is usable at any time after that initial setup, remove the incorrect devtype wwan.

2010-09-08introduce cx82310_eth: Conexant CX82310-based ADSL router USB ethernet driverOndrej Zary
This patch introduces cx82310_eth driver - driver for USB ethernet port of ADSL routers based on Conexant CX82310 chips. Such routers usually have ethernet port(s) too which are bridged together with the USB ethernet port, allowing the USB-connected machine to communicate to the network (and also internet through the ADSL, of course). This is my first driver, so please check thoroughly. As there's no protocol documentation, it was done with usbsnoop dumps from Windows driver, some parts (the commands) inspired by cxacru driver and also other usbnet drivers. The driver passed my testing - some real work and also pings sized from 0 to 65507 B. The only problem I found is the ifconfig error counter. When I return 0 (or 1 but empty skb) from rx_fixup(), usbnet increases the error counter although it's not an error condition (because packets can cross URB boundaries). Maybe the usbnet should be fixed to allow rx_fixup() to return empty skbs (or some other value, e.g. 2)? The USB ID of my device is 0x0572:0xcb01 which conflicts with some ADSL modems using cxacru driver (they probably use the same chipset but simpler firmware). The modems seem to use bDeviceClass 0 and iProduct "ADSL USB MODEM", my router uses bDeviceClass 255 and iProduct "USB NET CARD". The driver matches only devices with class 255 and checks for the iProduct string during init. I already posted a patch for the cxacru driver to ignore these devices.

2010-08-17ethtool: Provide a default implementation of ethtool_ops::get_drvinfoBen Hutchings
The driver name and bus address for a net_device can normally be found through the driver model now. Instead of requiring drivers to provide this information redundantly through the ethtool_ops::get_drvinfo operation, use the driver model to do so if the driver does not define the operation. Since ETHTOOL_GDRVINFO no longer requires the driver to implement any operations, do not require net_device::ethtool_ops to be set either.
