2023-11-27T05:23:28+00:00

minor fixup to keep things compiling. All the common forms in the tree

Remove $FreeBSD$: one-line .c pattern

2023-08-16T17:54:42+00:00

Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/

Clean up the vcs ID strings in libc's gen/ directory.

- Move CSRG IDs into __SCCSID().
- When a file has been copied, consistently use 'From: ' for strings
  referencing the version of the source file copied from in the license
  block comment.
- Some of the 'From:' tags were using $FreeBSD$ that was being expanded on
  each checkout.  Fix those to hardcode the FreeBSD tag from the file that
  was copied at the time of the copy.
- When multiple strings are present list them in "chronological" order,
  so CSRG (__SCCSID) before FreeBSD (__FBSDID).  If a file came from
  OtherBSD and contains a CSRG ID from the OtherBSD file, use the order
  CSRG -> OtherBSD -> FreeBSD.

General further adoption of SPDX licensing ID tags.

2017-11-20T19:49:47+00:00

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.

getusershell: don't write past end of line buffer reading local shells

2017-05-15T17:57:09+00:00

_local_initshells did not reset cp to the beginning of the line buffer
for every iteration that it called fgets(3), leading to writing past the
end of line with fairly long /etc/shells or excessively long line
lengths. Correct this by properly resetting cp.

Renumber copyright clause 4

2017-02-28T23:42:47+00:00

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.
