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.

/* Historically, the keys in _PATH_MP_DB/_PATH_SMP_DB had the format
|
|
* `1 octet tag | key', where the tag is one of the _PW_KEY* values
|
|
* listed below. These values happen to be ASCII digits. Starting
|
|
* with FreeBSD 5.1, the tag is now still a single octet, but the
|
|
* upper 4 bits are interpreted as a version. Pre-FreeBSD 5.1 format
|
|
* entries are version `3' -- this conveniently results in the same
|
|
* key values as before. The new, architecture-independent entries
|
|
* are version `4'.
|
|
* As it happens, some applications read the database directly.
|
|
* (Bad app, no cookie!) Thus, we leave the _PW_KEY* symbols at their
|
|
* old pre-FreeBSD 5.1 values so these apps still work. Consequently
|
|
* we have to muck around a bit more to get the correct, versioned
|
|
* tag, and that is what the _PW_VERSIONED macro is about.
