[PATCH 02/11] target: separate acl name from port ids

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The PGR code assumes the ACL name is going to be based on the SPC4
transportID type of values. The problem is that for iSCSI we have an
extra session id as part of the SCSI port id and some fabric modules
support or would like to support non transportID values for the ACL
name. For example, iSCSI and SRP would like to use the source address
for the ACL name, but that is not a valud transportID value that you
can get in a PGR request.

This patch adds a new transport_id struct which maps to the SPC
transportID. In the future will be used for PGR commands instead of
the ACL name. In this patchset, it is used to export the initiator
info in the session's sysfs dir, so tools can disply the info and
daemons that execute commands like PGRs in userspace can build a
session id to I_T nexus mapping.
