Mark usage function as __dead2 in programs where it does not return

2023-09-14T14:59:52Z

In most cases, usage does not return, so mark them as __dead2. For the cases where they do return, they have not been marked __dead2. Reviewed by: imp Pull Request: https://github.com/freebsd/freebsd-src/pull/735 (cherry picked from commit cccdaf507eee8fb34494b4624eb85bb951e323c8)

Remove extraneous setutxent() calls in write(1).

2019-01-23T20:02:17Z

We already call setutxent() once during initialization. Furthermore, the subsequent calls occur after the process has entered capability mode, so they fail, and attempts to fetch database entries fail as a result. PR: 235096 Submitted by: fullermd@over-yonder.net MFC after: 3 days

capsicum: use a new capsicum helpers in tools

Use caph_{rights,ioctls,fcntls}_limit to simplify the code.

Convert `cap_enter() < 0 && errno != ENOSYS` to `caph_enter() < 0`.

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 copyright clause 4

2017-02-28T23:42:47Z

Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96
