assert() only prevents -Wreturn-type from firing if asserts are
enabled. Use abort() so we don't do unexpected things even if we use
-UNDEBUG.

Subject: [PATCH] Fix -Wreturn-type issues.
To: selinux@tycho.nsa.gov
Cc: nnk@google.com,
sds@tycho.nsa.gov
assert() only prevents -Wreturn-type from firing if asserts are
enabled. Use abort() so we don't do unexpected things even if we use
-UNDEBUG.
Once __attribute__ ((format(printf, 1, 2))) is added to yyerror2,
"gcc -Wformat -Wformat-security" shows some issues. Fix them.

Both boolean and tunable keywords are processed by define_bool_tunable(),
argument 0 and 1 would be passed for boolean and tunable respectively.
For tunable, a TUNABLE flag would be set in cond_bool_datum_t.flags.
Note, when creating an if-else conditional we can not know if the
tunable identifier is indeed a tunable(for example, a boolean may be
misused in tunable_policy() or vice versa), thus the TUNABLE flag
for cond_node_t would be calculated and used in expansion when all
booleans/tunables copied during link.

1. Add a uint32_t "flavor" field and an ebitmap "roles" to the
role_datum_t structure;
2. Add a new "attribute_role" statement and its handler to declare
a role attribute;
3. Modify declare_role() to setup role_datum_t.flavor according
to the isattr argument;
4. Add a new "roleattribute" rule and its handler, which will record
the regular role's (policy value - 1) into the role attribute's
role_datum_t.roles ebitmap;
5. Modify the syntax for the role-types rule only to define the
role-type associations;
6. Add a new role-attr rule to support the declaration of a single
role, and optionally the role attribute that the role belongs to;
7. Check if the new_role used in role-transition rule is a regular role;
8. Support to require a role attribute;
9. Modify symtab_insert() to allow multiple declarations only for
the regular role, while a role attribute can't be declared more than once
and can't share a same name with another regular role.

This patch adds support for using the last path component as part of the
information in making labeling decisions for new objects. A example
rule looks like so:
type_transition unconfined_t etc_t:file system_conf_t eric;
This rule says if unconfined_t creates a file in a directory labeled
etc_t and the last path component is "eric" (no globbing, no matching
magic, just exact strcmp) it should be labeled system_conf_t.
The kernel and policy representation does not have support for such
rules in conditionals, and thus policy explicitly notes that fact if
such a rule is added to a conditional.

The boundry format mapped the primary field to a boolean in the
properties bitmap. This is appropriate for the kernel policy, but in
modular policy the primary field may be an integer that indicates the
primary type that is being aliased. In this case, the primary value cannot
be assumed to be boolean.
This patch creates a new module format that writes out the primary value
as was done before the boundry format.
