2020-09-15scsi: lpfc: Fix initial FLOGI failure due to BBSCN not supportedJames Smart1-24/+52
Initial FLOGIs are failing with the following message: lpfc 0000:13:00.1: 1:(0):0820 FLOGI Failed (x300). BBCredit Not Supported In a prior patch, the READ_SPARAM command was re-ordered to post after CONFIG_LINK as the driver is expected to update the driver's copy of the service parameters for the FLOGI payload. If the bb-credit recovery feature is enabled, this is fine. But on adapters were bb-credit recovery isn't enabled, it would cause the FLOGI to fail. Fix by restoring the original command order (READ_SPARAM before CONFIG_LINK), and after issuing CONFIG_LINK, detect bb-credit recovery support and reissuing READ_SPARAM to obtain the updated service parameters (effectively adding in the fix command order).

2020-09-09scsi: qla2xxx: Handle incorrect entry_type entriesDaniel Wagner1-2/+27
It was observed on an ISP8324 16Gb HBA with fw=8.08.203 (d0d5) in a PowerPC64 machine that pkt->entry_type was MBX_IOCB_TYPE/0x39 with an sp->type SRB_SCSI_CMD which is invalid and should not be possible. Reading the entry_type from the crash dump shows the expected value of STATUS_TYPE/0x03 but the call trace shows that qla24xx_mbx_iocb_entry() is used. Add a check to verify for consistency and reset the HBA if an invalid state is reached. Obviously, this is only a workaround until the real problem is solved.

Emit a warning when ->done or ->free are called on an already freed srb. There is a hidden use-after-free bug in the driver which corrupts the srb memory pool which originates from the cleanup callbacks. An extensive search didn't bring any lights on the real problem. The initial fix was to set both pointers to NULL and try to catch invalid accesses. But instead the memory corruption was gone and the driver didn't crash. Since not all calling places check for NULL pointer, add explicitly default handlers. With this we workaround the memory corruption and add a debug help.

2020-09-08scsi: qedi: Fix list_del corruption while removing active I/ONilesh Javali1-4/+11
While aborting the I/O, the firmware cleanup task timed out and driver deleted the I/O from active command list. Some time later the firmware sent the cleanup task response and driver again deleted the I/O from active command list causing firmware to send completion for non-existent I/O and list_del corruption of active command list. Add fix to check if I/O is present before deleting it from the active command list to ensure firmware sends valid I/O completion and protect against list_del corruption.

2020-09-08scsi: qedi: Skip firmware connection termination for PCI shutdown handlerManish Rangankar1-0/+4
In boot from SAN scenario when qedi PCI shutdown handler is called with active iSCSI sessions, sometimes target takes too long time to respond to firmware connection termination request. Instead skip sending termination ramrod and progress with unload path. Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Manish Rangankar <[email protected]> Signed-off-by: Martin K.
