USB: wusbcore: Remove redundant license text

2017-11-07T14:45:01Z

Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02Z

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

wusbcore: Fix one more crypto-on-the-stack bug

2017-01-10T16:03:42Z

The driver put a constant buffer of all zeros on the stack and pointed a scatterlist entry at it. This doesn't work with virtual stacks. Use ZERO_PAGE instead. Cc: stable@vger.kernel.org # 4.9 only Reported-by: Eric Biggers Signed-off-by: Andy Lutomirski Signed-off-by: Greg Kroah-Hartman

wusb: fix error return code in wusb_prf()

2016-10-19T13:28:29Z

Fix to return error code -ENOMEM from the kmalloc() error handling case instead of 0, as done elsewhere in this function. Fixes: a19b882c07a6 ("wusb: Stop using the stack for sg crypto scratch space") Signed-off-by: Wei Yongjun Signed-off-by: Greg Kroah-Hartman

wusb: Stop using the stack for sg crypto scratch space

2016-10-17T09:50:43Z

Pointing an sg list at the stack is verboten and, with CONFIG_VMAP_STACK=y, will malfunction. Use kmalloc for the wusb crypto stack space instead. Untested -- I'm not entirely convinced that this hardware exists in the wild. Signed-off-by: Andy Lutomirski Signed-off-by: Greg Kroah-Hartman
