Consider this simple test program: #include int main(int argc, char *argv[]) { cap_rights_t rights; cap_rights_init(&rights, CAP_WRITE); cap_rights_limit(1, &rights); return 0; } When ktraceing+kdumping it I get the following wrong output at the moment: 90024 bla STRU cap_rights_t CAP_MAC_GET,CAP_MAC_SET,CAP_SEM_GETVALUE,CAP_SEM_WAIT,CAP_EVENT,CAP_KQUEUE_= EVENT,CAP_IOCTL,CAP_PDWAIT,CAP_PDKILL,CAP_EXTATTR_DELETE,CAP_EXTATTR_GET,CA= P_EXTATTR_LIST,CAP_ACL_GET,CAP_KQUEUE_CHANGE I'd expect it to be 90024 bla STRU cap_rights_t CAP_WRITE The attached patch fixes this for me.
