2009-01-21usb/mcs7830: Don't use buffers from stack for USB transfersChristian Eggers
mcs7830_set_reg() and mcs7830_get_reg() are called with buffers from stack which must not be used directly for USB transfers. This causes corruption of the stack particulary on non x86 architectures because DMA may be used for these transfers.

2008-12-29drivers/net/usb: use USB API functions rather than constantsJulia Lawall
This set of patches introduces calls to the following set of functions: usb_endpoint_dir_in(epd) usb_endpoint_dir_out(epd) usb_endpoint_is_bulk_in(epd) usb_endpoint_is_bulk_out(epd) usb_endpoint_is_int_in(epd) usb_endpoint_is_int_out(epd) usb_endpoint_num(epd) usb_endpoint_type(epd) usb_endpoint_xfer_bulk(epd) usb_endpoint_xfer_control(epd) usb_endpoint_xfer_int(epd) usb_endpoint_xfer_isoc(epd) In some cases, introducing one of these functions is not possible, and it just replaces an explicit integer value by one of the following constants: USB_ENDPOINT_XFER_BULK USB_ENDPOINT_XFER_CONTROL USB_ENDPOINT_XFER_INT USB_ENDPOINT_XFER_ISOC In drivers/net/wireless/zd1211rw/zd_usb.c the code: (endpoint->bEndpointAddress & USB_TYPE_MASK) == USB_DIR_OUT is suspicious. If it is intended to use USB_ENDPOINT_DIR_MASK rather than USB_TYPE_MASK, then the whole conditional test could be converted to a call to usb_endpoint_is_bulk_in. An extract of the semantic patch that makes these changes is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r1@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) == - \(USB_ENDPOINT_XFER_CONTROL\|0\)) + usb_endpoint_xfer_control(epd) @r5@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) == - \(USB_DIR_IN\|0x80\)) + usb_endpoint_dir_in(epd) @inc@ @@ #include <linux/usb.h> @depends on !inc && (r1||r5)@ @@ + #include <linux/usb.h> #include <linux/usb/...> // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2008-12-16net: Refactor full duplex flow control resolutionSteve Glendinning
These 4 drivers have identical full duplex flow control resolution functions. This patch changes them all to use one common function. The function in question decides whether a device should enable TX and RX flow control in a standard way (IEEE 802.3-2005 table 28B-3), so this should also be useful for other drivers.

2008-12-16net: Move flow control definitions to mii.hSteve Glendinning

2008-11-12netdevice: safe convert to netdev_priv() #part-3Wang Chen
We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

2008-11-07[netdrvr] usb/hso: Cleanup rfkill error handlingJonathan McDowell
Yup, this appears to be the problem, thanks. I think &hso_net->net->dev is more intuitive for the error message, so I've used that. I've also added missing line endings on the error messages and set our local rfkill structure element to NULL on failure so we don't try to call rfkill_unregister on driver removal if we failed to register at all. The patch below Works For Me (TM); the device is detected fine, can be removed without problems and connects ok. I'll have a prod at why the rfkill stuff isn't working next, but I believe this cleanup of the error handling is appropriate no matter what the issue with registration is.
