The directly reason is the secure_mod_insmod boolean is used along with
pppd_can_insmod tunable in ppp.te in the tunable_policy() macro.
Apparently ppp.pp is linked first with the assumption of
secure_mod_insmod being required as a tunable. Later, when the module
that actually presents the definition of secure_mode_insmod is linked
the link process would find it is declared as a boolean. That's why you
have run into above error message.
I have taken Chris's suggestion to error out rather than just printing
warning messages about the mixture of any tunable with boolean. In order
to support this change Chris has transformed the definition of
pppd_can_insmod from gen_tunable() to gen_bool(), and use an explicit
if-else conditional to replace the call of tunable_policy(). (BTW, we
can use the boolean_policy() once the whole patchset is merged since
both pppd_can_insmod and secure_mode_insmod are booleans now)
Therefore please try to cherry-pick the commit of 68bbbbde to resolve
this problem.
Thanks,
Harry
