Changing the UEFI iSCSI Client's TargetPort min/max will effectively prevent the user from communicating with the targets configured to listen on ports outside that range (in your example: below 1024). I do not see a reason behind removing that flexibility. If user sets iSCSI target and client ports to values shared by other services, it is that user's mistake.

What kind of range of values for TargetPort do you propose? TARGET_PORT_MIN/MAX_NUM refer to a range of values (0-65535) that be set in TargetPort field in iSCSI HII. 3260 is a default TCP port for iSCSI. I see nothing wrong with that.

IANA Considerations This section conforms to [RFC2434]. The well-known user TCP port number for iSCSI connections assigned by IANA is 3260 and this is the default iSCSI port. Implementations needing a system TCP port number may use port 860, the port assigned by IANA as the iSCSI system port; however in order to use port 860, it MUST be explicitly specified - implementations MUST NOT default to use of port 860, as 3260 is the only allowed default. with my understanding, it wouid be good if we can change the below Min and MAX port number ranges with right ranges.<o:p></o:p> <o:p></o:p> #define TARGET_PORT_MIN_NUM 0<o:p></o:p> #define TARGET_PORT_MAX_NUM 65535<o:p></o:p> <o:p></o:p> Thanks<o:p></o:p> Siva<o:p></o:p> </div> This e-mail is intended for the use of the addressee only and may contain privileged, confidential, or proprietary information that is exempt from disclosure under law.
