netinet: Deduplicate most in_cksum() implementations

2021-12-01T12:42:43Z

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.

2017-11-20T19:43:44Z

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.

Delete stray clause 3 and renumber.

MFp4 bz_ipv6_fast:

2012-05-24T22:00:48Z

in_cksum.h required ip.h to be included for struct ip. To be able to use some general checksum functions like in_addword() in a non-IPv4 context, limit the (also exported to user space) IPv4 specific functions to the times, when the ip.h header is present and IPVERSION is defined (to 4). We should consider more general checksum (updating) functions to also allow easier incremental checksum updates in the L3/4 stack and firewalls, as well as ponder further requirements by certain NIC drivers needing slightly different pseudo values in offloading cases. Thinking in terms of a better "library". Sponsored by: The FreeBSD Foundation Sponsored by: iXsystems Reviewed by: gnn (as part of the whole) MFC After: 3 days

MFp4: Forget the asm inlined version of in_cksum_hdr(). It doesn't work if

2006-03-09T23:33:59Z

the pointer is unaligned, and it just doesn't worth it.

asm versions of in_cksum_hdr() and in_pseudo().

Use asm versions of in_cksum() and friends.

It only supports sa1110 (on simics) right now, but xscale support should come soon. Some of the initial work has been provided by : Stephane Potvin Most of this comes from NetBSD.
