libc: Purge unneeded cdefs.h

2023-11-27T04:20:09Z

These sys/cdefs.h are not needed. Purge them. They are mostly left-over from the $FreeBSD$ removal. A few in libc are still required for macros that cdefs.h defines. Keep those.

lib/libc/string/bcmp.c: fix integer overflow bug

2023-07-16T17:36:17Z

bcmp() returned the number of remaining bytes when the main loop exits. In case of a match, this is zero, else a positive integer. On systems where SIZE_MAX > INT_MAX, the implicit conversion from size_t to int in the return value may cause the number of remaining bytes to overflow, becoming zero and falsely indicating a successful comparison. Fix the bug by always returning 0 on equality, 1 otherwise.

General further adoption of SPDX licensing ID tags.

2017-11-20T19:49:47Z

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.

Renumber clauses to reduce diffs to other versions

NetBSD, OpenBSD, and Android's Bionic number the clauses 1 through 3, so follow suit to make comparison easier.

.In string.h with .In strings.h and adding a sentence to the HISTORY section. - Use an ANSI-C function definition. - Include instead of . - Apply style(9): Put a space after return keywords.

Make the rcsid and FreeBSD IDs more sane in the wcs* and wmem* files.

2001-05-24T08:47:42Z

Do the same for the non-wcs*/wmem* files while I'm here.
