[PATCH 3/4 v2] libsepol/cil: Add support for using qualified names to secil2tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Provide the option "-Q" or "--qualified-names" to indicate that the
policy is using qualified names.

Using qualified names means that declaration names can have "dots"
in them, but blocks, blockinherits, blockabstracts, and in-statements
are not allowed in the policy.

The libsepol function cil_set_qualified_names() is called with the
desired value for the CIL db's "qualified_names" field.
