iscsi-target: remove support for obsolete markers
Support for markers is currently broken because of a bug in
iscsi_enforce_integrity_rules(): the "IFMarkInt_Reject" and
"OFMarkInt_Reject" variables are always equal to 1 in
iscsi_enforce_integrity_rules().
Moreover, fixed interval markers keys (IFMarker, OFMarker, IFMarkInt
and OFMarkInt) are obsolete according to iSCSI RFC 7143:
>From http://tools.ietf.org/html/rfc7143#section-13.25:
13.25. Obsoleted Keys
This document obsoletes the following keys defined in [RFC3720]:
IFMarker, OFMarker, OFMarkInt, and IFMarkInt. However, iSCSI
implementations compliant to this document may still receive these
obsoleted keys -- i.e., in a responder role -- in a text negotiation.
When an IFMarker or OFMarker key is received, a compliant iSCSI
implementation SHOULD respond with the constant "Reject" value. The
implementation MAY alternatively respond with a "No" value.
However, the implementation MUST NOT respond with a "NotUnderstood"
value for either of these keys.
When an IFMarkInt or OFMarkInt key is received, a compliant iSCSI
implementation MUST respond with the constant "Reject" value. The
implementation MUST NOT respond with a "NotUnderstood" value for
either of these keys.
This patch disables markers by turning the corresponding parameters to
read-only. The default value of IFMarker and OFMarker remains "No" but
the user cannot change it to "Yes" anymore. The new value of IFMarkInt
and OFMarkInt is "Reject".
(Drop left-over iscsi_get_value_from_number_range + make configfs
parameters attrs R/W nops - nab)
