* netinet: Implement in_cksum_skip() using m_apply()Mark Johnston2021-11-241-31/+32
| | | | | | | | | | | | This allows it to work with unmapped mbufs. In particular, in_cksum_skip() calls no longer need to be preceded by calls to mb_unmapped_to_ext() to avoid a page fault.

* netinet: Deduplicate most in_cksum() implementationsMark Johnston2021-11-241-0/+257
| | | | | | | | | | | | | | | | | | | in_cksum() and related routines are implemented separately for each platform, but only i386 and arm have optimized versions. Other platforms' copies of in_cksum.c are identical except for style differences and support for big-endian CPUs. Deduplicate the implementations for the rest of the platforms. This will make it easier to implement in_cksum() for unmapped mbufs. On arm and i386, define HAVE_MD_IN_CKSUM to mean that the MI implementation is not to be compiled. No functional change intended.

* sys: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. 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. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326023
* Remove register keyword from sys/ and ANSIfy prototypesEd Maste2017-05-171-3/+3
| | | | | | | | | | | | | | | A long long time ago the register keyword told the compiler to store the corresponding variable in a CPU register, but it is not relevant for any compiler used in the FreeBSD world today. ANSIfy related prototypes while here. Reviewed by: cem, jhb Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D10193 Notes: svn path=/head/; revision=318389
* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.
