#45 Module versioning issues/confusion

[Carl Dawson]

The function/module in question is
dal_CSSM_ModuleLoadAndAttach() in the module
addins\intel\cssmdl\dal-dl\dal_callouts.cpp

CSSM_ModuleAttach() (Page 108 Version 2 of the CDSA
Technical Standard) calls clearly for the version
parameter to be the:

"The major and minor version number of CDSA that the
application is compatible with."

This is enforced in cssm.c during module loading, i.e.
version is checked against the constants CSSM_MAJOR
and CSSM_MINOR.

The code below is using the product version assigned
to the version member of the CSSM_SUBSERVICE_UID
structure itself documented as representing the
version of

"The version of the security service module"

This is backed up by the generic description of the
CSSM_VERSION structure which is:

"This structure is used to represent the version of
the CDSA components."

The actual use of the version is therefore slightly
ambiguous however I am sure the intention is that this
module loader is expecting the version of CDSA/CSSM
and not the version of the add-in module which is
intented to be supplied in the CSSM_SUBSERVICE_UID
structure.
