Bart Van Assche 0ca650c13b scsi: target/iscsi: Handle too large immediate data buffers correctly ... Since target_alloc_sgl() and iscsit_allocate_iovecs() allocate buffer space for se_cmd.data_length bytes and since that number can be smaller than the iSCSI Expected Data Transfer Length (EDTL), ensure that the iSCSI target driver does not attempt to receive more bytes than what fits in the receive buffer. Always receive the full immediate data buffer such that the iSCSI target driver does not attempt to parse immediate data as an iSCSI PDU. Note: the current code base only calls iscsit_get_dataout() if the size of the immediate data buffer does not exceed the buffer size derived from the SCSI CDB. See also target_cmd_size_check().
