This patch adds a new target_core_fabric_ops callback for allowing fabric drivers to expose a TPG attribute for signaling when a T10-PI protected fabric wants to function with an un-protected device without T10-PI. This specifically is to allow LIO to perform WRITE_STRIP + READ_INSERT operations when functioning with non T10-PI enabled devices, seperate from any available hw offloads the fabric supports. This is done using a new se_sess->sess_prot_type that is set at fabric session creation time based upon the TPG attribute. It currently cannot be changed for individual sessions after initial creation. Also, update existing target_core_sbc.c code to honor sess_prot_type when setting up cmd->prot_op + cmd->prot_type assignments. (Add unlikely and !! boolean conversion in sbc_check_prot - Sagi) Cc: Martin Petersen <martin.petersen@oracle.com> Cc: Sagi Grimberg <sagig@mellanox.com> Cc: Christoph Hellwig <hch@lst.de> Cc: Doug Gilbert <dgilbert@interlog.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org> |
