XDAS Standard Error Codes

One or more status codes are returned by each XDAS-API routine.
Two distinct sorts of status code are returned. These are termed XDAS status codes and minor status codes. An implementation of XDAS functions shall return XDAS_S_COMPLETE and other status values appropriate for the implementation of the function. The characteristics of a particular implementation may make some status returns inappropriate for that implementation.
XDAS-API routines return XDAS status codes as their integer function value. These codes indicate major status errors that are independent of the underlying mechanism used to provide the security service.
A XDAS status code can indicate a single fatal generic API error from the routine error and a single calling error. These errors are encoded into the 32-bit XDAS status code.
Changes to the original OpenGroup XDAS specification:
1) Moved XDAS_S_NOT_SUPPORTED from position 24 to position 27 because position 24 was in use twice (also by XDAS_S_RECORD_SYNTAX_ERROR)
2) Added XDAS_S_INVALID_FILTER_ACTION because it wasn't there, and all other types of filter information were represented (and used).

OpenXDAS Minor Status Codes.

These minor status codes are returned in the minor_status parameter of XDAS API functions as implemented by OpenXDAS.
These values are only returned in minor_status parameters if the return value of the API function is XDAS_S_FAILURE. All other XDAS return values set the minor_status output parameter to zero (OXDAS_MS_NO_ERROR).

XDAS Calling Error Codes

If a XDAS-API routine returns a XDAS status code containing a non-zero value, the call failed.
If the Calling Error field is non-zero, the invoking application�s call of the routine was erroneous. Calling errors are defined in Table 6-1 of the XDAS Preliminary Specification document.

#define XDAS_S_CALL_INACCESSIBLE_READ   (1 << 16)

#define XDAS_S_CALL_INACCESSIBLE_WRITE   (2 << 16)

#define XDAS_S_CALL_BAD_STRUCTURE   (3 << 16)

XDAS Error Macros

These macros may be used to extract routine or calling error codes from routine return values.
XDAS_ERROR simply returns true if the return value is an error.

#define XDAS_ROUTINE_ERROR(e)   ((e) & 0x0000FFFF)

#define XDAS_CALLING_ERROR(e)   ((e) & 0xFFFF0000)

#define XDAS_ERROR(e)   ((e) ? 1 : 0)

XDAS Basic Event Types

The generic set of XDAS events numbers.
XDAS conforming implementations are required to handle all these defined audit events as valid. An application or system developer that submits or imports security domain specific events to the XDAS service must map those events to these XDAS generic events or register their own set of audit events with the OpenGroup.
The following table is a duplicate of Figure 6-2 of the Open Group XDAS Preliminary Specification, and describes the bit-format of event types:

Bit: 01234 8 16 24 31 -------------------------------------- Format A: |0| set-id | event-id | -------------------------------------- Format B: |10| set-id | event-id | -------------------------------------- Format C: |110| set-id | event-id | -------------------------------------- Format D: |1110| event-id | -------------------------------------- Format E: |11111| reserved | --------------------------------------
Changes to the original OpenGroup XDAS specification:
1) The specified list of generic class A events had one duplicate at position 0x01000024, XDAS_AE_START_SYS was a duplicate of the previous event XDAS_AE_MODIFY_DATA_ITEM_CONTENTS. To maintain the event list order, each event from XDAS_AE_START_SYS to XDAS_AE_AUD_DS_CORR has been shifted up one numeric value.

XDAS Basic Event Classes

Similar to event numbers, event-class numbers encode the identification of an event-class set, as well as the identification of a unique event class within that set.
A set of event-class numbers is assigned (upon request) by the OpenGroup to an organization or a vendor. The organization or vendor then has the authority to use the the event-class numbers within that set.
Conceptually, each event class number is a pair (set-id, class-id), where set-id identifies an event-class set, and the class-id identifies an event class within in the set. In practice, each event-class number must have one of the formats illustrated in Figure 6-3 of the Open Group XDAS Preliminary Specification. This table is reproduced here:

Bit: 01234 8 16 24 31 -------------------------------------- Format A: |0| set-id | class-id | -------------------------------------- Format B: |10| set-id | class-id | -------------------------------------- Format C: |110| class-id | -------------------------------------- Format D: |111| reserved | --------------------------------------

XDAS Outcome Codes

XDAS outcome codes represent the outcome of a given event.
The outcome codes are structured into sets for SUCCESS, FAILURE, and DENIAL. Multiple codes from within one of these sets may be returned by a single call by combining them using a bitwise OR, but it is not permitted for outcome codes from the different sets to be returned by a single call.
For example, multiple SUCCESS codes may be returned by one call, but SUCCESS and FAILURE codes may not be returned by a single call.
Changes to the original OpenGroup XDAS specification:
1) There are two outcome tables in the XDAS preliminary specification. One is in section 4.4, Identification of Audit Events. The other is in section 6.11, XDAS Event Outcome Codes. These two tables are in disagreement with one another in several ways so the OpenXDAS implementation tries to compensate with executive decisions where necessary. The first issue is a missing event in section 6.11 which is specified in the table in section 4.4.4 - XDAS_OUT_ALREADY_ENABLED. Since XDAS_OUT_ALREADY_DISABLED exists in both tables, OpenXDAS assumes that the missing entry in section 6.11 is an oversight. Unfortunately, there is no slot in the bitmap for this addition. The value of XDAS_OUT_LOST_ASSOCIATION was reduced by one in order to make room in the bitmap for XDAS_OUT_ALREADY_ENABLED.
2) The remaining discrepencies are limited to simple naming differences in the definition names. Arbitrary decisions were made to choose the names for OpenXDAS. These include XDAS_OUT_NON_EXISTENT, XDAS_OUT_INSUFFICIENT_PRIVILEGE and XDAS_OUT_INVALID_CREDENTIALS.

XDAS Filter Types

Filters are used to set the criteria for preselecting events to be recorded, or for selecting records to be imported from an audit stream.
A filter expression is defined as a UTF-8 character string. It is a sequence of variable length fields, separated by colon (":") delimiters, as set out below. Note that if a colon is part of an alphanumeric string, then it shall be escaped. The format for a single filter expression is defined as:
include/exclude flag:attribute:operator:value
A filter may be defined as a list of filter expressions which shall be evaluated in the sequence in which they are listed. The intention is that a subsequent expression may define exceptions to previous expression.
For example, an expression may exclude a set of events based on event class, but a subsequent expression, based on event number, may specifically include a subset of the events otherwise excluded by reference to event class.

XDAS Event Action Masks

A filter may also define the disposition of an event submitted to, or imported into the XDAS service.
A filter action expression is defined as a UTF-8 character string. It is a sequence of variable length fields, separated by colon (":") delimiters, as set out below. Note that if a colon is part of an alphanumeric string, then it shall be escaped.
The format for a single filter expression is defined as:
action mask:text string
The components of the action mask are defined here. The format of the text string is implementation defined. A filter may be defined as a list of filter actions which shall be executed in the sequence in which they are listed.
Action bits may be OR'd together to indicate that multiple actions are desired for a given class of events.

Functions

XDAS General Audit Service API

All callers must initiate a session with the XDAS before they can use any of the services it provides.
The initialization of the session supports the mutual authentication of the audit client and audit service components and establishes the audit client�s XDAS authorities. The caller is returned a handle to the XDAS service which is then used for all XDAS API functions. On completion, the caller must terminate the XDAS session.
