|

*
|
|
* osstrace() is called:
|
|
*
|
|
* - once for each builtin ASN.1 type, regardless of tagging, with the
|
|
* field "kind" set to valueTrace. So given a PDU of value "fooBar":
|
|
*
|
|
* Sample DEFINITIONS EXPLICIT TAGS ::= BEGIN
|
|
* fooBar Foo ::= {age 6, living TRUE}
|
|
* Foo ::= SET {age INTEGER, living [1] [2] Alive}
|
|
* Alive ::= BOOLEAN
|
|
* END
|
|
*
|
|
* it is called called three times with "kind" set to valueTrace - once
|
|
* for the SET, once for the INTEGER, and once for the BOOLEAN.
|
|
*
|
|
* When the traceRecord "kind" field is set to valueTrace ...
|
|
*
|
|
* The field "identifier" contains the component identifier of
|
|
* the type if one is present in the ASN.1 definition. So in
|
|
* the above example, "identifier" will be empty on the call for
|
|
* the SET, while on the call for the INTEGER it will contain "age",
|
|
* and "living" on the call for the BOOLEAN.
|
|
*
|
|
* The field "typeReference" contains the name of the associated ASN.1
|
|
* typereference, if any. So in the above example, "typeReference"
|
|
* will contain "Foo" on the call for the SET, "Alive" on the call
|
|
* for the BOOLEAN, and will be empty on the call for the INTEGER.
|
|
*
|
|
* The field "builtinTypeName" contains the name of the ASN.1 builtin
|
|
* type. So in the above example, "builtinTypeName" will contain
|
|
* "SET", "INTEGER", and "BOOLEAN" on the calls as appropriate.
|
|
* Note that for all character string types "builtinTypeName" is
|
|
* set to "Character String". This will be changed in the near future
|
|
* to reflect the true character string type.
|
|
*
|
|
* The field "taggingCount" contains the number of entries in the array
|
|
* of tag_length structs pointed to by tagging.tag_length, and reflects
|
|
* the number of tags present in the encoding. Note that an entry
|
|
* exists in the tag_length array for each ANY and CHOICE value as
|
|
* though they had tags defined for them in the ASN.1 Standard. So in
|
|
* the above example, "taggingCount" is 1 on the calls for the SET and
|
|
* INTEGER, and on the call for the BOOLEAN "taggingCount" is 3 since
|
|
* EXPLICIT TAGS is in effect.
|
|
*
|
|
* The field "tagging.tag_length" points to an array of tag_length
|
|
* structs.
|
|
*
|
|
* The field "tagging.tag_length->tag" is the BER tag represented
|
|
* in the form CCTTTTTTTTTTTTTT with "CC" the class number, and
|
|
* "TTTTTTTTTTTTTT" the tag number. Since the ANY and CHOICE
|
|
* types do not have tags of their own, the last entry in the
|
|
* tag_length array for these types always has 0 as the value of
|
|
* the "tag" field. So in the above example, "tag" is 0x11 on the
|
|
* call for the the SET.
|
|
*
|
|
* The field "tagging.tag_length->length" is the length of the
|
|
* encoded value if the length is of definite form (i.e.,
|
|
* "definite" is 1).
|
|
*
|
|
* The field "tagging.tag_length->definite" indicates when the
|
|
* length is definite or indefinite. This field is significant
|
|
* only if "tag" is non-zero.
|
|
*
|
|
* The field "fieldKind" indicates whether the number in "field" is:
|
|
* -- the position of a component within a SET or SEQUENCE, or
|
|
* -- the PDU number assigned by the ASN.1 compiler, or
|
|
* -- the position of a component within a SET OF or SEQUENCE OF, or
|
|
* -- the position of a substring within a constructed string.
|
|
* "fieldKind" is significant only if "field" is non-zero. So in
|
|
* the example above, "fieldKind" has a value of pduNumber on the
|
|
* call for the SET, and a value of setOrSequenceField on the calls for
|
|
* the INTEGER and BOOLEAN.
|
|
*
|
|
* The field "fieldNumber" is a ordinal number indicating the position
|
|
* of a component within a SET, SEQUENCE, SET OF, SEQUENCE OF, or
|
|
* constructed string, or the PDU number assigned by the ASN.1 compiler.
|
|
* So in the above example, "fieldNumber" is 1 (the PDU number) on the
|
|
* call for the SET, 1 (the position of the component "age") on the
|
|
* call for the INTEGER, and 2 (the position of the component "living"
|
|
* on the call for the BOOLEAN.
|
|
*
|
|
* The field "depth" is the level of nesting of the value relative to
|
|
* the outermost type, which has a "depth" value of 0. So in the above
|
|
* example, "depth" is 0 on the call for the SET, and 1 on the calls
|
|
* for the INTEGER and BOOLEAN.
|
|
*
|
|
* The field "primitive" is set to 1 if the builtin ASN.1 type is
|
|
* simple (i.e., the primitive/constructed bit in the identifier
|
|
* octet is set to 0), so it is 0 for SET, SEQUENCE, SET OF, SEQUENCE
|
|
* OF, and CHOICE because they are structured. It is also set to 0 if
|
|
* the type is an ANY. It is 1 for all other builtin types.
|
|
*
|
|
* The field "value" contains formatted data if the builtin type
|
|
* is simple or ANY, regardless of tagging. Hence, in the above
|
|
* example the call for SET will not contain any data in "value"
|
|
* (because the builtin type is a constructed type), while for the
|
|
* INTEGER and BOOLEAN types "value" will contain formatted data.
|
|
* The maximum number of bytes of formatted data placed into "value"
|
|
* is controlled by the external variable "asn1chop". If "asn1chop"
|
|
* is set to 0 the maximum length of the traced value is determined
|
|
* by the maximum internal buffer size variable, "ossblock".
|
|
*
|
|
* - once for each end-of-contents octets pair that is generated/
|
|
* encountered while encoding/decoding a constructed value whose
|
|
* length is of the indefinite-length form. A call with a "valueTrace"
|
|
* record is always made to osstrace() before one is made with an
|
|
* "endOfContentsTrace" record.
|
|
*
|
|
* A single "endOfContentsTrace" call is made to osstrace() for each
|
|
* builtin type that is processed if the indefinite-length form of
|
|
* encoding is used. If the builtin type is a structured type (CHOICE,
|
|
* SET, SEQUENCE, SET OF, SEQUENCE OF) then there may be multiple
|
|
* "valueTrace" and possible "endOfContentsTrace" calls made to
|
|
* osstrace() before the matching "endOfContentsTrace" call is made.
|
|
*
|
|
* When the traceRecord "kind" field is set to endOfContentsTrace ...
|
|
*
|
|
* The field "taggingCount" contains the number of entries in the array
|
|
* of "depth" indicators pointed to by tagging.depth, and reflects
|
|
* the nesting of each pair of end-of-contents-octets associated with
|
|
* the builtin type being encoded/decoded. So in the above example,
|
|
* if indefinite-length encoding is being used, "taggingCount" will
|
|
* be 1 on the call for the SET (since it has a single constructed
|
|
* tag), and 2 on the call for the BOOLEAN (since it has two explicit
|
|
* tags, for which the "constructed" bit in the encoding must be set).
|
|
*
|
|
* The field "tagging.depth" points to an array of "depth" indicators
|
|
* that reflect the nesting of each pair of end-of-contents-octets
|
|
* associated with a builtin type. So in the above example, if
|
|
* indefinite-length encoding is being used, "tagging.depth" will point
|
|
* to a single 0 on the call for the SET since it has a single tag for
|
|
* which the constructed bit is set; while on the call for the BOOLEAN
|
|
* "tagging.depth" will point to an array whose two entries are 1 and 2
|
|
* since there are two explicit tags on the BOOLEAN.
|
|
*
|
|
* All other fields in the traceRecord are insignificant for an
|
|
* endOfContentsTrace record.
|
|
*
|
|
* - once for each value that is skipped while decoding, with a "kind"
|
|
* value of skippedFieldTrace. The skippedFieldTrace "kind" is just
|
|
* means of indicating that an unexpected value was encountered in the
|
|
* message and is being skipped. This is not an error if the type is
|
|
* extensible.
|
|
*
|
|
* When the traceRecord "kind" field is set to skippedFieldTrace ...
|
|
*
|
|
* The field of the traceRecord are the same as when "kind" is set to
|
|
* valueTrace, except that:
|
|
* -- the skipped value is always reported as having one tag, hence
|
|
* -- there is only one entry in the tag_length array.
|
|
* -- the content of the field "value" is always "<skipped>", and
|
|
* -- "typeReference" is always NULL.
|
|
*
|
|
* - once for each error message issued, in which case the "kind" field
|
|
* is set to messageTrace.
|
|
*
|
|
* When the traceRecord "kind" field is set to messageTrace the "value"
|
|
* field contains the error message, and other fields are
|
|
* insignificant.

|
|

|
|
* We classified ASN.1 types in to the following:

|
|
* (1). For all primitive types (including ANY), the prtType in traceRecord

* is set to primeType, length is the total length of the content

|
* length = nbytes.nbits, and the total length should be 8*nbytes+nbits.
|
|
* If the length is not encoded, "(not encoded)" will be added to the

|
* output string. For BIT STRING with length longer than 64K (bits), and

* for OCTET STRING longer that 16K (bytes), fragmentation is needed
|
|
* and this is indicated by the string "fragment = n" after the length.
|
|
* The fragmentation index is field fragment in traceRecord.
|
|
* (2). For SEQUENCE and SET, prtType is seqsetType. In this case, the length
|
|
* in traceRecord is the fieldcount of the SEQUENCE or SET.
|
|
* (3). For SEQUENCE OF and SET OF, prtType is seqofType, and the length
|
|
* in traceRecord is the count of components in the SEQUENCE OF (SET OF).
|
|
* (4). For CHOICE, prtType is choiceType, and the length field in
|
|
* traceRecord indicates the choice index.
|
|
* (5). Total number of bits for the entire encoding is reported at the end
|
|
* of encoding and decoding. The prtType for this trace is closeType.
