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.

net: sched: Introduce connmark action This tc action allows you to retrieve the connection tracking mark This action has been used heavily by openwrt for a few years now. There are known limitations currently: doesn't work for initial packets, since we only query the ct table. Fine given use case is for returning packets no implicit defrag. frags should be rare so fix later.. won't work for more complex tasks, e.g. lookup of other extensions since we have no means to store results we still have a 2nd lookup later on via normal conntrack path. This shouldn't break anything though since skb->nfct isn't altered. V2: remove unnecessary braces (Jiri) change the action identifier to 14 (Jiri) Fix some stylistic issues caught by checkpatch V3: Move module params to bottom (Cong) Get rid of tcf_hashinfo_init and friends and conform to newer API (Cong) Acked-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: David S.
