initial_sid context via libsepol

["Roberts, William C" <william.c.roberts@xxxxxxxxx>]

 

How can one obtain the same value as /sys/fs/selinux/initial_contexts/file via libsepol?

 

I’ve been digging around libsepol and its not quite clear to me.

 

It looks as though the record is here:

                context_struct_t *a = &((policydb_t *)pol.db)->ocontexts[OCON_ISID]->context[0];

                context_struct_t *b = &((policydb_t *)pol.db)->ocontexts[OCON_ISID]->context[1];

 

                printf("%u\n", a->type);

                printf("%u\n",b->type);

 

Prints:

185

0

 

Not sure if this is right, and how to format the context struct to a string. I didn’t see any helpers.

 

Thanks,

Bill
