    SubjectRe: [PATCH] ACL supports to mqueue
    From
    Thank you James for your viewing.

    * In general, it can give a more fine grained and flexible DAC to msg queue obj.
    * NFSARK(A distro) wants all posix ipc objects to support ACL, including mqueue.
    * Posix semphore and shmem both support ACL, but mqueue as one of the
    three basic ipc doesn't.
    * At least, it may save one note sentence for MQ_OVERVIEW(7) ^_^
    "Linux does not currently (2.6.26) support the use of access
    control lists (ACLs) for POSIX message queues."
