The NFS dissector (all versions) show access types that have not been requested
to be checked as "not allowed" in the call and reply. This is incorrect and
misleading. At present one must manually compare what was requested in order
to assess if access was actually denied for that type. When there are hundreds
or thousands of these ACCESS requests in a capture, it is not possible or
practical to manually check each one.
The submitted patch does the following:
* Passes the access mask in the call to the reply for comparison
* Adds filterable fields for each supported (v4) and access type
* Adds a pseudo field, nfs.access_denied
* Lists the access types to be checked in the summary and tree
* Separately lists the supported, denied, and allowed access types in the
summary and tree
The changes are applied to all NFS versions.
