Hi all: I have been playing with target discovery authentication (CHAP) for my iSCSI targets, and I noticed something I don't understand. Once I set a discovery mutual userid and password in directory /sys/kernel/config/target/iscsi/discovery_auth, I see that the value for "authenticate_target" gets set to 1. But if I clear out the userid_mutual and password_mutual fields, authenticate_target is still set. Looking at the code, the only way it seems I can clear this value is by writing the literal string "NULL" to either userid_mutual or password_mutual. If this is correct, can somebody explain why this is not a bug? It seems like software trying to interpret the value of these attributes will have to test for both "" and "NULL" to see if the field is logically empty. -- Lee Duncan -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
