MFC r357284, r357419: stdio unlocked

2020-02-13T03:13:29Z

r357284: stdio: provide _unlocked variants of fflush, fputc, fputs, fread, fwrite fflush_unlocked is currently desired in ports by sysutils/metalog, and redefined as the locked fflush. fputc_unlocked, fputs_unlocked, fread_unlocked, and fwrite_unlocked are currently desired in ports by devel/elfutils, and redefined as the locked fputs, fread, and fwrite respectively. r357419: libc: provide fputc_unlocked Among the same justification as the other stdio _unlocked; in addition to an inline version in , we must provide a function in libc as well for the functionality. This fixes the lang/gcc* builds, which want to use the symbol from libc.

MFC r352056:

Include update to stdio.h missed in r331936.

In my attempt to limit the commit in r331936 to only the gets_s() commit and not include unrelated patches in my tree, this patch was missed. Reported by: pfg MFC after: 2 weeks X-MFC with: r331936 Differential Revision: https://reviews.freebsd.org/D12785

include: further adoption of SPDX licensing ID tags.

2017-11-20T19:45:28Z

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.

libthr: fix warnings from GCC when WARNS=6

2017-05-23T16:12:50Z

Fix warnings about: - redundant declarations - a local variable shadowing a global function (dlinfo) - an old-style function definition (with an empty parameter list) - a variable that is possibly used uninitialized "make tinderbox" passes this time, except for a few unrelated kernel failures.

Make use of clang nullability attributes.

2017-01-28T20:54:43Z

Replace uses of the GCC __nonnull__ attribute with the clang nullability qualifiers. The replacement should be transparent for clang developers as the new qualifiers will produce the same warnings and will be useful for static checkers but will not cause aggressive optimizations. GCC will not produce such warnings and developers will have to use upgraded GCC ports built with the system headers from r312538.
