Kyle Evans 0cd95859c8 [2/3] Add an initial seal argument to kern_shm_open() ... Now that flags may be set on posixshm, add an argument to kern_shm_open() for the initial seals. To maintain past behavior where callers of shm_open(2) are guaranteed to not have any seals applied to the fd they're given, apply F_SEAL_SEAL for existing callers of kern_shm_open. A special flag could be opened later for shm_open(2) to indicate that sealing should be allowed. We currently restrict initial seals to F_SEAL_SEAL. We cannot error out if F_SEAL_SEAL is re-applied, as this would easily break shm_open() twice to a shmfd that already existed. A note's been added about the assumptions we've made here as a hint towards anyone wanting to allow other seals to be applied at creation.
