Looking at policy/mls, I see this:
# the peer/packet recv op
mlsconstrain { peer packet } { recv }
        (( l1 dom l2 ) or
         (( t1 == mlsnetreadtoclr ) and ( h1 dom l2 )) or
         ( t1 == mlsnetread ));

mlsnetreadtoclr appears to only be granted via:
policy/modules/kernel/mls.if: mls_socket_read_to_clearance
which is not granted to racoon_t


Hello,

We have ipsec working again, using something like:

($local_t and $remote_t being the local and remote types)

mls_socket_read_to_clearance(racoon_t)

allow $local_t $remote_t:association polmatch;
allow $remote_t $local_t:association polmatch;

allow $local_t $remote_t:peer recv;

Thanks for the tips,

Joshua Roys
