These are described respectively in the .Xr au_class 3 , .Xr au_control 3 , .Xr au_event 3 , .Xr au_mask 3 , .Xr au_notify 3 , .Xr au_stream 3 , .Xr au_token 3 , and .Xr au_user 3 manual pages. .Ss Audit Event Stream Interfaces Audit event stream interfaces support interaction with file-backed audit event streams: .Xr au_close 3 , .Xr au_close_buffer 3 , .Xr au_free_token 3 , .Xr au_open 3 , .Xr au_write 3 , .Xr audit_submit 3 . .Ss Audit Class Interfaces Audit class interfaces support the look up of information from the .Xr audit_class 5 database: .Xr endauclass 3 , .Xr getauclassent 3 , .Xr getauclassent_r 3 , .Xr getauclassnam 3 , .Xr getauclassnam_r 3 , .Xr setauclass 3 . .Ss Audit Control Interfaces Audit control interfaces support the look up of information from the .Xr audit_control 5 database: .Xr endac 3 , .Xr setac 3 , .Xr getacdir 3 , .Xr getacfilesz 3 , .Xr getacflg 3 , .Xr getacmin 3 , .Xr getacna 3 , .Xr getacpol 3 , .Xr au_poltostr 3 , .Xr au_strtopol 3 . .Ss Audit Event Interfaces Audit event interfaces support the look up of information from the .Xr audit_event 5 database: .Xr endauevent 3 , .Xr setauevent 3 , .Xr getauevent 3 , .Xr getauevent_r 3 , .Xr getauevnam 3 , .Xr getauevnam_r 3 , .Xr getauevnonam 3 , .Xr getauevnonam_r 3 , .Xr getauevnum 3 , .Xr getauevnum_r 3 . .Ss Audit I/O Interfaces Audit I/O interfaces support the processing and printing of tokens, as well as the reading of audit records: .Xr au_fetch_tok 3 , .Xr au_print_tok 3 , .Xr au_read_rec 3 . .Ss Audit Mask Interfaces Audit mask interfaces convert support the conversion between strings and .Vt au_mask_t values. They may also be used to determine if a particular audit event is matched by a mask: .Xr au_preselect 3 , .Xr getauditflagsbin 3 , .Xr getauditflagschar 3 . .Ss Audit Notification Interfaces Audit notification routines track audit state in a form permitting efficient update, avoiding frequent system calls to check the kernel audit state: .Xr au_get_state 3 , .Xr au_notify_initialize 3 , .Xr au_notify_terminate 3 . These interfaces are implemented only for Darwin/Mac OS X. .Ss Audit Token Interface Audit token interfaces permit the creation of tokens for use in creating audit records for submission to event streams. Each interface converts a C type to its .Vt token_t representation: .Xr au_to_arg 3 , .Xr au_to_arg32 3 , .Xr au_to_arg64 3 , .Xr au_to_attr64 3 , .Xr au_to_data 3 , .Xr au_to_exec_args 3 , .Xr au_to_exec_env 3 , .Xr au_to_exit 3 , .Xr au_to_file 3 , .Xr au_to_groups 3 , .Xr au_to_header32 3 , .Xr au_to_header64 3 , .Xr au_to_in_addr 3 , .Xr au_to_in_addr_ex 3 , .Xr au_to_ip 3 , .Xr au_to_ipc 3 , .Xr au_to_ipc_perm 3 , .Xr au_to_iport 3 , .Xr au_to_me 3 , .Xr au_to_newgroups 3 , .Xr au_to_opaque 3 , .Xr au_to_path 3 , .Xr au_to_process 3 , .Xr au_to_process32 3 , .Xr au_to_process64 3 , .Xr au_to_process_ex 3 , .Xr au_to_process32_ex 3 , .Xr au_to_process64_ex 3 , .Xr au_to_return 3 , .Xr au_to_return32 3 , .Xr au_to_return64 3 , .Xr au_to_seq 3 , .Xr au_to_sock_inet 3 , .Xr au_to_sock_inet32 3 , .Xr au_to_sock_inet128 3 , .Xr au_to_socket_ex 3 , .Xr au_to_subject 3 , .Xr au_to_subject32 3 , .Xr au_to_subject64 3 , .Xr au_to_subject_ex 3 , .Xr au_to_subject32_ex 3 , .Xr au_to_subject64_ex 3 , .Xr au_to_text 3 , .Xr au_to_trailer 3 , .Xr au_to_zonename 3 . .Ss Audit User Interfaces Audit user interfaces support the look up of information from the .Xr audit_user 5 database: .Xr au_user_mask 3 , .Xr endauuser 3 , .Xr setauuser 3 , .Xr getauuserent 3 , .Xr getauuserent_r 3 , .Xr getauusernam 3 , .Xr getauusernam_r 3 , .Xr getfauditflags 3 . .Ss Audit Constant Conversion Interfaces These functions convert between BSM and local constants, including the .Xr errno 2 number, socket type, and protocol famil spaces, and must be used to generate and interpret BSM return and extended socket tokens: .Xr au_bsm_to_domain 3 , .Xr au_bsm_to_errno 3 , .Xr au_bsm_to_fcntl_cmd 3 , .Xr au_bsm_to_socket_type 3 , .Xr au_domain_to_bsm 3 , .Xr au_errno_to_bsm 3 , .Xr au_fcntl_cmd_to_bsm 3 , .Xr au_socket_type_to_bsm 3 . .Sh SEE ALSO .Xr au_class 3 , .Xr au_domain 3 , .Xr au_errno 3 , .Xr au_mask 3 , .Xr au_notify 3 , .Xr au_socket_type 3 , .Xr au_stream 3 , .Xr au_token 3 , .Xr au_user 3 , .Xr audit_submit 3 , .Xr audit_class 5 , .Xr audit_control 5 .Sh HISTORY The OpenBSM implementation was created by McAfee Research, the security division of McAfee Inc., under contract to Apple Computer, Inc., in 2004. It was subsequently adopted by the TrustedBSD Project as the foundation for the OpenBSM distribution. .Sh AUTHORS .An -nosplit This software was created by .An Robert Watson , .An Wayne Salamon , and .An Suresh Krishnaswamy for McAfee Research, the security research division of McAfee, Inc., under contract to Apple Computer, Inc. .Pp The Basic Security Module (BSM) interface to audit records and audit event stream format were defined by Sun Microsystems. .Sh BUGS Bugs would not be unlikely. .Pp The .Nm library implementations are generally thread-safe, but not reentrant. .Pp The assignment of routines to classes could use some work, as it is decidely ad hoc. For example, .Fn au_read_rec should probably be considered a stream routine.
