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".
