License cleanup: add SPDX license identifier to uapi header files with no license Many user space API headers are missing licensing information, which makes it hard for compliance tools to determine the correct license. By default are files without license information under the default license of the kernel, which is GPLV2. Marking them GPLV2 would exclude them from being included in non GPLV2 code, which is obviously not intended. The user space API headers fall under the syscall exception which is in the kernels COPYING file: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". otherwise syscall usage would not be possible. Update the files which contain no license information with an SPDX license identifier. The chosen identifier is 'GPL-2.0 WITH Linux-syscall-note' which is the officially assigned identifier for the Linux syscall exception. SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

staging/usbip: add uapi header to export usbip kernel interfaces usbip userspace has duplicated enum definition to report usbip device status maintained by the kernel. Adding an usbip uapi header file will define the kernel - userspace interface for this device status. This new uapi file is added under usbip/uapi to keep the staging tree code self-contained. When usbip moves to mainline drivers, this file should be moved under uapi/linux Signed-off-by: Shuah Khan <shuah.kh@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

usbip: add USBIP_URB_* URB transfer flags USBIP driver packs URB transfer flags in network packets that are exchanged between Server (usbip_host) and Client (vhci_hcd). URB_* flags are internal to kernel and could change. Where as USBIP URB flags exchanged in network packets are USBIP user API must not change. Add USBIP_URB* flags to make this an explicit API and change the client and server to map them. Details as follows: Client tx path (USBIP_CMD_SUBMIT): - Maps URB_* to USBIP_URB_* when it sends USBIP_CMD_SUBMIT packet. Server rx path (USBIP_CMD_SUBMIT): - Maps USBIP_URB_* to URB_* when it receives USBIP_CMD_SUBMIT packet. Flags aren't included in USBIP_CMD_UNLINK and USBIP_RET_SUBMIT packets and no special handling is needed for them in the following cases: - Server rx path (USBIP_CMD_UNLINK) - Client rx path & Server tx path (USBIP_RET_SUBMIT) Update protocol documentation to reflect the change.
