General further adoption of SPDX licensing ID tags.

2017-11-20T19:49:47Z

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.

Renumber copyright clause 4

2017-02-28T23:42:47Z

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. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96

Just exit in the child if execve(2) fails.

2016-03-08T18:05:20Z

No functional change. This is mostly addressing a false-positive from the clang static analyzer due to it thinking that done() was being called with freed memory, however the kill(0, SIGTERM) made the done() never reached. It doesn't make sense to the show the footer from the child anyhow, nor does it make sense to kill the process group here since the execve(2) failed in the child. This code was leftover from many years of refactoring. MFC after: 1 week Sponsored by: EMC / Isilon Storage Division

Filemon: Attach from the child to avoid racing with the parent attach.

2016-03-08T18:05:02Z

This is the same as how the bmake filemon usage works. This also fixes failed attach not properly flushing the TTY. MFC after: 1 week Relnotes: yes Sponsored by: EMC / Isilon Storage Division
