would like to take regarding function re-use. It seems like some pre-processing may be necessary; i.e. resolve the source operator before inserting the script content into the <fix> tag. The goal is to only have one copy of a specific function saved in the SSG repo but to be able to use it for multiple <fix>es which differ only in one parameter.
Maybe the text substitution of <plain-text> could be considered for this task. According to NISTIR-7275r4, the xccdf:sub element within xccdf:fix may refer to the xccdf:plain-text element.
Hence, SSG may use plain-text elements for definition of common scripts or functions. And only refer to such single plain-text from all of the Rules.
The example of <plain-text> usage is in OpenSCAP unittests at:
http://git.fedorahosted.org/cgit/openscap.git/tree/tests/API/XCCDF/unittests...
and
http://git.fedorahosted.org/cgit/openscap.git/tree/tests/API/XCCDF/unittests...
This is fantastic, thank you Simon! I went through your unit test scripts and got a few ideas on improving SSG (outside of remediation).
I won't get a chance to try this until late Sunday, but we should easily be able to transform "functions" as existing in current Tresys scripts. Someone feel free to shoot out a first draft/patch!
