When a file name in type transition rule used in an interface is same as
a keyword, it needs to be M4 escaped so that the keyword is not expanded
by M4, e.g.
- filetrans_pattern($1, virt_var_run_t, virtinterfaced_var_run_t, dir, "interface")
+ filetrans_pattern($1, virt_var_run_t, virtinterfaced_var_run_t, dir, "``interface''")
But sepolgen-ifgen could not parse such string:
# sepolgen-ifgen
Illegal character '`'
This change allows M4 escaping inside quoted strings and fixed described
problem.
