scsi: qla2xxx: Fix partial flash write of MBI

For new adapters with multiple flash regions to write to, current code
allows FW & Boot regions to be written, while other regions are blocked via
sysfs. The fix is to block all flash read/write through sysfs interface.

On excessive bit errors for the FCP channel ingress fibre path, the channel

record.  Since performance can become suboptimal with I/O timeouts due to

User explanation of new kernel message:

 * Description:
 * The FCP channel reported that its bit error threshold has been exceeded.
 * These errors might result from a problem with the physical components
 * of the local fibre link into the FCP channel.
 * The problem might be damage or malfunction of the cable or
 * cable connection between the FCP channel and
 * the adjacent fabric switch port or the point-to-point peer.
 * Find details about the errors in the HBA trace for the FCP device.
 * The zfcp device driver closed down the FCP device
 * to limit the performance impact from possible I/O command timeouts.
 * User action:
 * Check for problems on the local fibre link, ensure that fibre optics are
 * clean and functional, and all cables are properly plugged.
 * After the repair action, you can manually recover the FCP device by
 * writing "0" into its "failed" sysfs attribute.
 * If recovery through sysfs is not possible, set the CHPID of the device

command is lost and replaced with the value set by the execution of the
request sense command. This value may in many instances be unaligned to the
device sector size, causing sd_done() to print a warning message about the
incorrect unaligned resid before the command is retried.

Fix this problem by saving the original command residual in struct
scsi_eh_save using scsi_eh_prep_cmnd() and restoring it in
scsi_eh_restore_cmnd(). In addition, to make sure that the request sense
command is executed with a correctly initialized command structure, also
reset the residual to 0 in scsi_eh_prep_cmnd() after saving the original
command value in struct scsi_eh_save.

Saurav Kashyap [Fri, 23 Aug 2019 09:52:39 +0000 (02:52 -0700)]
scsi: qedf: Initiator fails to re-login to switch after link down

Problem Statement:

 - Driver has fc_id of 0xcc0200

 - Driver gets link down (due to test) and calls fcoe_ctlr_link_down().

 - At this point, the fc_id of the initiator port is zeroed out.

 - Driver gets a link up 14 seconds later.

 - Driver performs FIP VLAN request, gets a response from the switch.

 - No change in VLAN is detected.

 - Driver then notifies libfcoe via fcoe_ctlr_link_up().

 - Libfcoe then issues a multicast discovery solicitation as expected.

 - Cisco FCF responds to that correctly.

 - Libfcoe at this point starts a 3 sec count-down to allow any other FCFs
   to be discovered. However, at this point, it has been 20 seconds since
   the last FKA from the driver (which would have been sent prior to
   backlink toggle), which causes the CVL to be issued from Cisco CVL from
   the switch is dropped by the driver as the vx_port identification
   descriptor is present and has value of 0xcc0200, which does not match
   the driver's value of 0.  Libfcoe completes the 3 sec count down and
   proceeds to issue FLOGI as per protocol.  Switch rejects FLogi request.
   All subsequent FLOGI requests from libfc are rejected by the switch
   (possibly because it is now expecting a new solicitation).  This
   situation will continue until the next link toggle.

Solution:

The Vx_port descriptor in the CVL has three fields:

MAC address
Fabric ID
Port Name

Today, the code checks for both #1 and #2 above. In the case where we went
through a link down, both these will be zero until FLOGI succeeds.

We should change our code to check if any one of these 3 is valid and if
so, handle the CVL (basically switching from AND to OR). The port name
field is definitely expected to be valid always.
