Vendor branch import of TrustedBSD OpenBSM 1.0 alpha 6: - Use AU_TO_WRITE and AU_NO_TO_WRITE for the 'keep' argument to au_close(); previously we used hard-coded 0 and 1 values. - Add man page for au_open(), au_write(), au_close(), and au_close_buffer(). - Support a more complete range of data types for the arbitrary data token: add AUR_CHAR (alias to AUR_BYTE), remove AUR_LONG, add AUR_INT32 (alias to AUR_INT), add AUR_INT64. - Add au_close_token(), which allows writing a single token_t to a memory buffer. Not likely to be used much by applications, but useful for writing test tools. - Modify au_to_file() so that it accepts a timeval in user space, not just kernel -- this is not a Solaris BSM API so can be modified without causing compatibility issues. - Define a new API, au_to_header32_tm(), which adds a struct timeval argument to the ordinary au_to_header32(), which is now implemented by wrapping au_to_header32_tm() and calling gettimeofday(). #ifndef KERNEL the APIs that invoke gettimeofday(), rather than having a variable definition. Don't try to retrieve time zone information using gettimeofday(), as it's not needed, and introduces possible failure modes. - Don't perform byte order transformations on the addr/machine fields of the terminal ID that appears in the process32/subject32 tokens. These are assumed to be IP addresses, and as such, to be in network byte order. - Universally, APIs now assume that IP addresses and ports are provided in network byte order. APIs now generally provide these types in network byte order when decoding. - Beginnings of an OpenBSM test framework can now be found in openbsm/test. This code is not built or installed by default. - auditd now assigns more appropriate syslog levels to its debugging and error information. - Support for audit filters introduced: audit filters are dynamically loaded shared objects that run in the context of a new daemon, auditfilterd. The daemon reads from an audit pipe and feeds both BSM and parsed versions of records to shared objects using a module API. This will provide a framework for the writing of intrusion detection services. - New utility API, audit_submit(), added to capture common elements of audit record submission for many applications.

Vendor import of OpenBSM 1.0 alpha 11, with the following change history notes since the last import: OpenBSM 1.0 alpha 11 - Reclassify certain read/write operations as having no class rather than the fr/fw class; our default classes audit intent (open) not operations (read, write). - Introduce AUE_SYSCTL_WRITE event so that BSD/Darwin systems can audit reads and writes of sysctls as separate events. Add additional kernel environment and jail events for FreeBSD. - Break AUDIT_TRIGGER_OPEN_NEW into two events, AUDIT_TRIGGER_ROTATE_USER (issued by the user audit(8) tool) and AUDIT_TRIGGER_ROTATE_KERNEL (issued by the kernel audit implementation) so that they can be distinguished. - Disable rate limiting of rotate requests; as the kernel doesn't retransmit a dropped request, the log file will otherwise grow indefinitely if the trigger is dropped. - Improve auditd debugging output. - Fix a number of threading related bugs in audit_control file reading routines. - Add APIs au_poltostr() and au_strtopol() to convert between text representations of audit_control policy flags and the flags passed to auditon(A_SETPOLICY) and retrieved from auditon(A_GETPOLICY). - Add API getacpol() to return the 'policy:' entry from audit_control, an extension to the Solaris file format to allow specification of policy persistent flags. - Update audump to print the audit_control policy field. - Update auditd to read the audit_control policy field and set the kernel policy to match it when configuring/reconfiguring. Remove the -s and -h arguments as these policies are now set via the configuration file. If a policy line is not found in the configuration file, continue with the current default of setting AUDIT_CNT. - Fix bugs in the parsing of large execve(2) arguments and environmental variable tokens; increase maximum parsed argument and variable count. - configure now detects strlcat(), used by policy-related functions. - Reference token and record sample files added to test tree.

.Sh DESCRIPTION
These interfaces allow applications to allocate audit records, construct a
record using a series of tokens, and commit the audit record to the system
event log.
An extension API is also provided to commit the record to an in-memory
buffer rather than the system audit log.
.Pp
The
.Fn au_open
interface allocates a new audit record descriptor.
.Pp
The
.Fn au_write
interface adds a token to an allocated audit descriptor.
When a token has been successfully added to a record, the caller no longer
owns the token memory, and does not need to free it directly via a call to
.Xr au_free_token 3 .
.Pp
The
.Fn au_close
function is used to commit an audit record to the system audit log, or
abandon the record.
In either cases, all resources associated with the record will be released.

Vendor import of OpenBSM 1.0 alpha 11, with the following change history notes since the last import: OpenBSM 1.0 alpha 11 - Reclassify certain read/write operations as having no class rather than the fr/fw class; our default classes audit intent (open) not operations (read, write). - Introduce AUE_SYSCTL_WRITE event so that BSD/Darwin systems can audit reads and writes of sysctls as separate events. Add additional kernel environment and jail events for FreeBSD. - Break AUDIT_TRIGGER_OPEN_NEW into two events, AUDIT_TRIGGER_ROTATE_USER (issued by the user audit(8) tool) and AUDIT_TRIGGER_ROTATE_KERNEL (issued by the kernel audit implementation) so that they can be distinguished. - Disable rate limiting of rotate requests; as the kernel doesn't retransmit a dropped request, the log file will otherwise grow indefinitely if the trigger is dropped. - Improve auditd debugging output. - Fix a number of threading related bugs in audit_control file reading routines. - Add APIs au_poltostr() and au_strtopol() to convert between text representations of audit_control policy flags and the flags passed to auditon(A_SETPOLICY) and retrieved from auditon(A_GETPOLICY). - Add API getacpol() to return the 'policy:' entry from audit_control, an extension to the Solaris file format to allow specification of policy persistent flags. - Update audump to print the audit_control policy field. - Update auditd to read the audit_control policy field and set the kernel policy to match it when configuring/reconfiguring. Remove the -s and -h arguments as these policies are now set via the configuration file. If a policy line is not found in the configuration file, continue with the current default of setting AUDIT_CNT. - Fix bugs in the parsing of large execve(2) arguments and environmental variable tokens; increase maximum parsed argument and variable count. - configure now detects strlcat(), used by policy-related functions. - Reference token and record sample files added to test tree.

.Sh BUGS
Currently,
.Fn au_open
does not reserve kernel resources necessary to commit the record to the
trail; on systems supporting
.Fn au_close ,
the call will block until resources are available to commit the record.
However, this leads to the possibility of an action being permitted without
the record being guaranteed to go to disk.
Ideally,
.Fn au_open
would reserve resources necessary to commit any submitted record, releasing
them on
.Fn au_close .
