Notes
insert_right est la manière dont launchd et les enregistrements bootstrap publient un send right vers un service : le daemon alloue un receive right, puis demande à launchd d'insérer un send right sous un nom bien connu dans l'espace IPC des clients (de façon transparente, via bootstrap_check_in / lookup). Le trap accepte les dispositions MACH_MSG_TYPE_MAKE_SEND, MAKE_SEND_ONCE, COPY_SEND, MOVE_SEND et MOVE_SEND_ONCE, reflétant la sémantique des descripteurs mach_msg. Une mauvaise utilisation — insertion sous un nom déjà pris ou avec une disposition incompatible — retourne KERN_NAME_EXISTS ou KERN_INVALID_VALUE.
Détection
Invisible pour Endpoint Security. DTrace mach_trap::_kernelrpc_mach_port_insert_right_trap:entry est la sonde directe ; corréler les insertions avec les noms bootstrap via launchctl print peut révéler des publications de services non autorisées.
