But HBA fills port_name and port_id of the LOGO command with all zeroes, which is not valid. The initiator sends a reject for this command, but it is not being processed on the target, since it assumes LOGO can never fail. This leaves a system in a state where the initiator thinks it is still logged in to the target and can send commands to it, but the target ignores all incoming commands from this initiator. If, in such a situation, the initiator sends some command (e.g. during a scan), after not receiving a response for a timeout duration, it sends ABORT for the command. After a timeout on receiving an ABORT response, the initiator sends LOGO to the target. Only after that, the initiator can successfully relogin to the target and restore the connection. In the end, this whole situation hangs the system for approximately a minute. By default, the driver sends a LOGO command to HBA filling only port_id, expecting HBA to match port_id with the correct port_name from it's internal table. HBA doesn't do that, instead filling these fields with all zeroes. This patch makes the driver send a LOGO command to HBA with port_name and port_id in the I/O PARMETER fields. HBA then copies these values to corresponding fields in the LOGO command frame.
