* cmp: Check the status of stdout.Dag-Erling Smørgrav2024-10-091-16/+19
| | | | | | | | | | POSIX requires us to print an error message and exit non-zero if writing to stdout fails. This can only happen if sflag is unset. MFC after: 3 days Sponsored by: Klara, Inc. Reviewed by: markj Differential Revision: https://reviews.freebsd.org/D47020

* Fix handling of rights on stdio streams, take two.Mark Johnston2019-02-251-8/+17
| | | | | | | | | | | | | | | | | | | Split the rights-limiting code into two cases: if one of the input files isn't a regular file, use caph_limit_stream(3) instead of open-coding the same logic; if both input files are regular files, and the initial attempts to map them succeed, we limit the rights on those files to CAP_MMAP_R. Add a regression test for PR 234885.

* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=326025
* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | 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.

The handler does not attempt to distinguish errors from file truncation, but anyone actively modifying a file while trying to compare it shouldn't even expect something sane to happen.
