File Context problem

File Context problem

[Daniel J Walsh]

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=251001	

As this bugzilla points out, we are somewhat inconsistant on the handling of file context.  Currently we treat homedirs differently then we do file_context generated by a policy module.  So the sort order seems to go

semanage fcontext -a : Highest 
genhomedircon   : Second
semodule -i : third

So the question is should the context of genhomedircon and semodule -i be treated the same.

/etc/selinux/TYPE/context/files/file_contexts
/etc/selinux/TYPE/context/files/file_contexts.homedirs

I think local should override everything else.

That ordering is applied by libselinux matchpathcon (now the label_file
back-end).

The bug report isn't quite right; if they had specified a pathname with
no regex characters (i.e. escaped the "." as "\."), then it would have
taken precedence over any regex expression.  libselinux moves exact
pathname specs to the end to give them precedence over any regex
expression.
