Use this when adding values obtained from the input patch.

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

* bspatch: Remove backwards-compatibility sys/capability.h supportEd Maste2016-09-201-4/+1
| | | | | | | | | | | | | | | bspatch previously included sys/capability.h or sys/capsicum.h based on __FreeBSD_version, as FreeBSD is the upstream for bsdiff and we may see this file incorporated into other third-party software. The Capsicum header is now installed as sys/capsicum.h in stable/10 and FreeBSD 10.3, so we can just use sys/capsicum.h and simplify the logic.

* Add bsdiff and bspatch to the base system. These are tools forColin Percival2005-08-061-0/+203
constructing and applying binary patches; in particular, they perform well (in the sense of constructing small patches) for executable code. Both portsnap (coming to the base system Real Soon Now) and FreeBSD Update (coming to the base system a bit later) use bspatch. This is the same code as the bsdiff-4.2 which has been in the ports tree (misc/bsdiff) for the past year, with the following exceptions: 1. The license is now the traditional 2-clause BSD; 2. Instead of forking and execing bzip2, the code now uses libbz2; and 3. Some minor changes have been made to fit this code into the base system (adding $FreeBSD$ tags, putting bsdiff and bspatch into separate directories, etc.) This code is rather ugly and has lots of style bugs (mostly because I wrote it before I had ever heard of style(9)). Some day I'll come back and clean it up. Discussed on: freebsd-arch MFC before: 5.5-RELEASE Tested by: Several million users (earlier version). Notes: svn path=/head/; revision=148771
