spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix

Revert "Reimplement strlen" This reverts commit 710e45c4b8539d028877769f1a4ec088c48fb5f1. It breaks for some corner cases on big endian ppc64. Given the stage of the release process it is best to revert for now. Reported by: jhibbits

Reimplement strlen The previous code neglected to use primitives which can find the end of the string without having to branch on every character. While here augment the somewhat misleading commentary -- strlen as implemented here leaves performance on the table, especially so for userspace. Every arch should get a dedicated variant instead. In the meantime this commit lessens the problem. Tested with glibc test suite. Naive test just calling strlen in a loop on Haswell (ops/s): $(perl -e "print 'A' x 3"): before: 211198039 after: 338626619 $(perl -e "print 'A' x 100"): before: 83151997 after: 98285919

Port the NetBSD KCSAN runtime to FreeBSD. Update the NetBSD Kernel Concurrency Sanitizer (KCSAN) runtime to work in the FreeBSD kernel. It is a useful tool for finding data races between threads executing on different CPUs. This can be enabled by enabling KCSAN in the kernel config, or by using the GENERIC-KCSAN amd64 kernel. It works on amd64 and arm64, however the later needs a compiler change to allow -fsanitize=thread that KCSAN uses. Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D22315

sys/kern: adoption of SPDX licensing ID tags. 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.

Make the long-awaited change from $Id$ to $FreeBSD$ This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.
