Avoid implicit gcc nonnull attribute in vwarnx().

2018-01-28T19:37:30Z

We removed the nonnull attributes from our headers long ago, but still __printflike() includes it implicitly. This will cause the NULL check to be optimized away in higher -O levels and it will also trigger a -Wnonnull-compare warning. Avoid warning with it in vwarnx().

include: further adoption of SPDX licensing ID tags.

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.

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.

called . o will continue to live so it can define MD clock macros, which are only MD because of gratuitous differences between architectures. o Change all headers to make use of this. This mainly involves changing: #ifdef _BSD_FOO_T_ typedef _BSD_FOO_T_ foo_t; #undef _BSD_FOO_T_ #endif to: #ifndef _FOO_T_DECLARED typedef __foo_t foo_t; #define _FOO_T_DECLARED #endif Concept by: bde Reviewed by: jake, obrien

Join continuation lines that fit in 80 columns after removal of __P(()).

Breath deep and take __P out of the system include files.

Don't forget to use the appropriate __printflike attribute for verr

and vwarn*. Sorted attributes. UnFrom'ed vendor id.

Add support for -Wformat consistency checking between format strings

and their argument lists for the err(3) family of functions. Note, I intentionally used __printflike instead of __printf0like for warnx. Although a NULL format string is legal for that function, it doesn't make any sense.
