SEC14 — SECIOP ContextId

CORBA Security SECIOP.

In SECIOP, one RTF changed a field in the SECIOP Message Header
from

struct ulonglong

;

// This should be changed to unsigned long long
typedef ulonglong ContextId;

to

typedef unsigned long long ContextId;

because of the introduction of the long long type into CORBA.

This modification changes the specification the CDR encoding of the
structure, because what was compact 8 byte sequence aligned on a 4 byte
boundary. now became an 8 byte sequence aligned on an 8 byte boundary.

Each SECIOP message is preceded with a GIOP Message header, which is 12
bytes. Each SECIOP message, which is specified by a struct, starts with
the ContextId. Strict interpretation of the encoding rules makes the
SECIOP messages incompatiable, as the space between the header and the
message must now contain 4 bytes padding.

Proposed Resolution: revert back to the struct ulonglong definition.
