* Remove copyright strings ifdef'd outWarner Losh2023-11-271-9/+0
| | | | | | | | | | | We've ifdef'd out the copyright strings for some time now. Go ahead and remove the ifdefs. Plus whatever other detritis was left over from other recent removals. These copyright strings are present in the comments and are largely from CSRG's attempt at adding their copyright to every binary file (which modern interpretations of the license doesn't require).

* 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
* Add a new getty/gettytab capability to generate an initial message dynamically.David Bright2017-09-071-0/+2
| | | | | | | | | | | | | | | | | | | This modification adds a new gettytab(5) option (iM) to specify a program to run that will generate the initial (banner) message that is displayed before the login prompt. Such a capability is useful when dynamic information is needed in the banner message that cannot be supplied by the set of % substitution sequences available in the "im" option.

* Add a new libc function: cfmakesane(3).Ed Schouten2010-11-021-5/+7
| | | | | | | | | | | | | | I've noticed various terminal emulators that need to obtain a sane default termios structure use very complex `hacks'. Even though POSIX doesn't provide any functionality for this, extend our termios API with cfmakesane(3), which is similar to the commonly supported cfmakeraw(3), except that it fills the termios structure with sane defaults. Change all code in our base system to use this function, instead of depending on <sys/ttydefaults.h> to provide TTYDEF_*. Notes: svn path=/head/; revision=214680
