License cleanup: add SPDX license identifier to uapi header files with no license

2017-11-02T10:19:54Z

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.

RDMA/netlink: Add netlink device definitions to UAPI

2017-08-10T10:28:07Z

Introduce new defines to rdma_netlink.h, so the RDMA configuration tool will be able to communicate with RDMA subsystem by using the shared defines. The addition of new client (NLDEV) revealed the fact that we exposed by mistake the RDMA_NL_I40IW define which is not backed by any RDMA netlink by now and it won't be exposed in the future too. So this patch reuses the value and deletes the old defines. The NLDEV operates with objects. The struct ib_device has two straightforward objects: device itself and ports of that device. This brings us to propose the following commands to work on those objects: * RDMA_NLDEV_CMD_{GET,SET,NEW,DEL} - works on ib_device itself * RDMA_NLDEV_CMD_PORT_{GET,SET,NEW,DEL} - works on ports of specific ib_device Those commands receive/return the device index (RDMA_NLDEV_ATTR_DEV_INDEX) and port index (RDMA_NLDEV_ATTR_PORT_INDEX). For device object accesses, the RDMA_NLDEV_ATTR_PORT_INDEX will return the maximum number of ports for specific ib_device and for port access the actual port index. The port index starts from 1 to follow RDMA/core internal semantics and the sysfs exposed knobs. Signed-off-by: Leon Romanovsky Reviewed-by: Steve Wise
