General further adoption of SPDX licensing ID tags. 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.

Merge of 4.4-Lite2 sh source, plus some gcc -Wall cleaning. This is a merge of parallel duplicate work by Steve Price and myself. :-] There are some changes to the build that are my fault... mkinit.c was trying (poorly) to duplicate some of the work that make(1) is designed to do. The Makefile hackery is my fault too, the depend list was incomplete because of some explicit OBJS+= entries, so mkdep wasn't picking up their source file #includes. This closes a pile of /bin/sh PR's, but not all of them.. Submitted by: Steve Price <steve@bonsai.hiwaay.net>, peter

char **p; /* parameter list */
sh: Make getopts memory-safe if with changing arguments. POSIX does not permit to continuing a getopts loop with different arguments. For parsing the positional parameters, we handle this case by resetting the getopts state when the positional parameters are changed in any way (and the getopts state is local to a function). However, in the syntax getopts <optstring> <var> <arg...>, changes could lead to invalid memory access. In the syntax getopts <optstring> <var> <arg...>, store a copy of the arguments and continue to use them until getopts is reset.

sh: Add set -o pipefail The pipefail option allows checking the exit status of all commands in a pipeline more easily, at a limited cost of complexity in sh itself. It works similarly to the option in bash, ksh93 and mksh. Like ksh93 and unlike bash and mksh, the state of the option is saved when a pipeline is started. Therefore, even in the case of commands like A | B & a later change of the option does not change the exit status, the same way (A | B) & works. Since SIGPIPE is not handled specially, more work in the script is required for a proper exit status for pipelines containing commands such as head that may terminate successfully without reading all input. This can be something like ( cmd1 r=$? if [ "$r" -gt 128 ] && [ "$(kill -l "$r")" = PIPE ]; then exit 0 else exit "$r" fi ) | head PR: 224270 Relnotes: yes

sh: Add set -o nolog. POSIX requires this to prevent entering function definitions in history but this implementation does nothing except retain the option's value. In ksh88, function definitions were usually entered in the history file, even when they came from ~/.profile and the $ENV file, to allow displaying their definitions. This is also the first option that does not have a letter.

Fix warnings, some of them serious because sh violated name spaces reserved by the header files it includes. mkinit.c still produces C code with redundant declarations, although they are more harmless since they automatically derived from the right places.
