include: ssp: round out fortification of current set of headers

2024-07-13T05:16:24Z

ssp/ssp.h needed some improvements: - `len` isn't always a size_t, it may need casted - In some cases we may want to use a len that isn't specified as a parameter (e.g., L_ctermid), so __ssp_redirect() should be more flexible. - In other cases we may want additional checking, so pull all of the declaration bits out of __ssp_redirect_raw() so that some functions can implement the body themselves. strlcat/strlcpy should be the last of the fortified functions that get their own __*_chk symbols, and these cases are only done to be consistent with the rest of the str*() set.

ssp: appease -Wgnu-statement-expression-from-macro-expansion

2024-05-14T23:22:18Z

It's a stupid warning, but some ports enable it by default and were already defining _FORTIFY_SOURCE, thus exposing the new macros immediately. This at least fixes the libfido2 build, perhaps others as well. While we're here, fix a fresh build of stand w/ FORTIFY_SOURCE enabled by not pulling in the ssp headers if _STANDALONE is defined. We do not have runtime support in libsa as of the time of writing. Reported by: netchild Sponsored by: Stormshield Sponsored by: Klara, Inc.

Add a build knob for _FORTIFY_SOURCE

2024-05-13T05:23:50Z

In the future, we will Default to _FORTIFY_SOURCE=2 if SSP is enabled, otherwise default to _FORTIFY_SOURCE=0. For now we default it to 0 unconditionally to ease bisect across older versions without the new symbols, and we'll put out a call for testing. include/*.h include their ssp/*.h equivalents as needed based on the knob. Programs and users are allowed to override FORTIFY_SOURCE in their Makefiles or src.conf/make.conf to force it off.

spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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

include: General further adoption of SPDX licensing ID tags.

2017-11-25T17:09:43Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified 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.

Add explicit_bzero(3) and its kernel counterpart.
