* Re-arrange some of the code to separate writable user tree variables fromStefan Eßer2020-11-021-28/+27

* Make sysctl user.local a tunable that can be written at run-timeStefan Eßer2020-10-311-10/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | This sysctl value had been provided as a read-only variable that is compiled into the C library based on the value of _PATH_LOCALBASE in paths.h. After this change, the value is compiled into the kernel as an empty string, which is translated to _PATH_LOCALBASE by the C library. This empty string can be overridden at boot time or by a privileged user at run time and will then be returned by sysctl. When set to an empty string, the value returned by sysctl reverts to _PATH_LOCALBASE. This update does not change the behavior on any system that does not modify the default value of user.localbase. I consider this change as experimental and would prefer if the run-time write permission was reconsidered and the sysctl variable defined with CLFLAG_RDTUN instead to restrict it to be set at boot time.

* Add read only sysctl variable user.localbaseStefan Eßer2020-10-301-0/+9
| | | | | | | | | | | | The value is provided by the C library as for other sysctl variables in the user tree. It is compiled in and returns the value of _PATH_LOCALBASE defined in paths.h.

* Clean up the vcs ID strings in libc's gen/ directory.John Baldwin2018-07-031-3/+1
| | | | | | | | | | | | | | | | | | | | - Move CSRG IDs into __SCCSID(). - When a file has been copied, consistently use 'From: <tag>' 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.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.

* Add proper const keywords to sysctl(3) parameters.Ed Schouten2010-02-211-7/+4
| | | | | | | | | | | | | | | | The `name' and `newp' arguments can be marked const, because the buffers they refer to are never changed. While there, perform some other cleanups: - Remove K&R from sysctl.c. - Implement sysctlbyname() using sysctlnametomib() to prevent duplication of an undocumented kernel interface. - Fix some whitespace nits. It seems the prototypes are now in sync with NetBSD as well. Notes: svn path=/head/; revision=204170
