From 0df138476c8306478d6e726f044868b4bccf411c Mon Sep 17 00:00:00 2001 From: Swen Schillig Date: Tue, 5 Oct 2010 17:12:53 +0200 Subject: [SCSI] zfcp: Fix adapter activation on link down If an exchange config is executed while the local link is down, the request succeeds but the returned data is incomplete. Proceeding with the adapter activation is leading to an unpredictable behaviour (e.g. kernel panic) caused by invalid values. In such a scenario the recommended ERP is to retry the action and wait for a link up event. If the issue persists the activation has to fail.

The implementation seems fine on the surface, but any VN_Ports added using the NPIV feature will have their own MAC addresses and these MACs were not being checked, which prevented any NPIV VN_Ports from receiving frames. In other words, the following patch has broken NPIV. 519e5135e2537c9dbc1cbcc0891b0a936ff5dcd2 [SCSI] fcoe: adds src and dest mac address checking for fcoe frames Part of the offending patch is correct, but the part that broke NPIV was attempting to satisfy FC-BB-5 section D.5, 2.1- (discard frames that) "contain a destination MAC address/destination N_Port_ID pair that was not assigned by an FCF to one of the VN_Ports on the ENode" The language does _not_ say to compare the destination FC-MAP/destination N_Port_ID, but instead to compare the destination MAC address/destination N_Port_ID. >From the FC-BB-5 specification, "A properly formed FPMA is one in which the 24 most significant bits equal the Fabric’s FC-MAP value and the least significant 24 bits equal the N_Port_ID assigned to the VN_Port by the FCF." This means that we need to compare the FC Frame's destination FCID against the embedded FCID in the destination MAC address. This patch checks the lower 24 bits of the destination MAC address against destination FCID in the Fibre Channel frame. For MAC validation the first line of defense is the hardware MAC filtering. Each VN_Port will have a unicast MAC addresses added to the hardware's filtering table. The Ethernet driver should drop any MACs not destined for a programmed MAC. This patch adds a second line of defense that very specfically compares an element in the FC frame against an element in the Ethernet header, which is appropriate for the FCoE layer. Many alternative approaches were considered, including a LLD callback from libfc. The second most reasonable approach seemed to be walking the list of NPIV ports and check each of their MAC addresses against the destination MAC address of the received frame. The problem with this approach was that it is likely that performance would suffer with the more NPIV ports added to the system since every received frame would need to walk this list, comparing each entry's MAC.

This patch removes the use of the port down retry counter as a mechanism to update a fcport state. The internal driver counter is a residual carry-over from pre-FC-transport aware driver inteaction. The ql2xport_down_retry module parameter and NVRAM set ha->port_down_retry_count remain in order to seed the fc-host's default dev-loss-tmo.

Currently when we receive a CS_RESET as a response for a SCSI command the driver will return DID_TRANSPORT_DISRUPTED back to the SCSI mid-layer. There are certain circumstances where this could cause the mid-layer to exhaust all of its retries if the FC port goes away for a short time. This will result in commands being prematurly failed. Moving the CS_RESET return code to be grouped with other link level events will cause the FC transport layer to block that target's queue thus preventing the premature exhaustion of retries.

Allows checking of fcf after last ndlp released so that fcf can be released if no longer in use. - Replaced individual FCF_XXXX_DISC flag clearing in lieu of aggregate FCF_DISCOVERY flag upon succesful completion of flogi. - Correct setting of altBbCredit value in sparams to correct issue with logins with remote loop-based devices.

At that point, the driver should set the last in-use remote node devloss timeout flag if it was not already set and should perform proper action on the in-use FCF and recover of FCF from firmware, depending on the state the driver's FIP engine is in. Find eligible FCF through FCF table rescan or the next new FCF event when FCF table rescan turned out empty eligible FCF, and the successful flogi into an FCF shall clear the HBA_DEVLOSS_TMO flag, indicating the successful recovery from devloss timeout.

Prior to final reset, the driver must wait for all XRIs to return from the adapter. Added logic to poll, progressively slowing the poll rate as delay gets longer. - Correct behavior around the rsvd1 field in UNREG_RPI_ALL mailbox completion and final rpi cleanup. - Updated logic to move pending VPI registrations to their completion in cases where a CVL may be received while registration in progress. - Added unreg all rpi mailbox command before unreg vpi.

Scatter-gather enables a write/read of multiple none-contiguous areas of an object, in a single call. The extents may overlap and/or be in any order. The Scatter-Gather list is sent to the target in what is called a "cdb continuation segment". This is yet another possible segment in the osd-out-buffer. It is unlike all other segments in that it sits before the actual "data" segment (which until now was always first), and that it is signed by itself and not part of the data buffer. This is because the cdb-continuation-segment is considered a spill-over of the CDB data, and is therefor signed under OSD_SEC_CAPKEY and higher. TODO: A new osd_finalize_request_ex version should be supplied so the @caps received on the network also contains a size parameter and can be spilled over into the "cdb continuation segment". Thanks to John Chandy for the original code, and investigations. And the implementation of SG support in the osd-target.

Add the Online Controller Reset (OCR) to the Driver. + OCR is the new feature for megaraid_sas driver which + will allow the fw to do the chip reset which will not + affact the OS behavious. + + To add the OCR support, driver need to do: + a). reset the controller chips -- Xscale and Gen2 which + will change the function calls and add the reset function + related to this two chips. + + b). during the reset, driver will store the pending cmds + which not returned by FW to driver's pending queue. Driver + will re-issue those pending cmds again to FW after the OCR + finished. + + c). In driver's timeout routine, driver will report to + OS as reset. Also driver's queue routine will block the + cmds until the OCR finished. + + d). in Driver's ISR routine, if driver get the FW state as + state change, FW in Failure status and FW support online controller + reset (OCR), driver will start to do the controller reset. + + e). In driver's IOCTL routine, the application cmds will wait for the + OCR to finish, then issue the cmds to FW. + + f). Before driver kill adapter, driver will do last chance of + OCR to see if driver can bring back the FW. + +2. Add the support update flag to the driver to tell LSI megaraid_sas + application which driver will support the device update.

In driver's timeout routine, driver will do three time reset if fw is in + failed state. Driver will kill adapter if can't bring back FW after the + this three times reset. +4.
