2017-11-02License cleanup: add SPDX license identifier to uapi header files with no ↵Greg Kroah-Hartman1-0/+1
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.

2014-02-17ipsec: add support of limited SA dumpNicolas Dichtel1-1/+14
The goal of this patch is to allow userland to dump only a part of SA by specifying a filter during the dump. The kernel is in charge to filter SA, this avoids to generate useless netlink traffic (it save also some cpu cycles). This is particularly useful when there is a big number of SA set on the system. Note that I removed the union in struct xfrm_state_walk to fix a problem on arm. struct netlink_callback->args is defined as a array of 6 long and the first long is used in xfrm code to flag the cb as initialized. Hence, we must have: sizeof(struct xfrm_state_walk) <= sizeof(long) * 5. With the union, it was false on arm (sizeof(struct xfrm_state_walk) was sizeof(long) * 7), due to the padding. In fact, whatever the arch is, this union seems useless, there will be always padding after it. Removing it will not increase the size of this struct (and reduce it on arm).
