2013-02-22[SCSI] qla2xxx: Do link initialization on get loop id failure.Joe Carnuccio

2013-02-22[SCSI] qla2xxx: Correct race in loop_state assignment during reset handling.Andrew Vasquez
There's a subtle race in the loop/bus-reset handling whereby a VHA's loop-state can get incorrectly set to 'down' after the loop-reset and firmware's completion of link re-negotiation. The original code incorrectly assumes that firmware AENs would arrive only after mailbox-command execution to initiate the link-flap. Here's a good case with the old code (AENs arrive after mailbox-command completion): qla2xxx [0000:03:00.1]-8012:91: BUS RESET ISSUED nexus=91:0:4. qla2xxx [0000:03:00.1]-287d:91: FCPort state transitioned from ONLINE to LOST - portid=010100. qla2xxx [0000:03:00.1]-580e:91: Asynchronous P2P MODE received. qla2xxx [0000:03:00.1]-287d:91: FCPort state transitioned from ONLINE to LOST - portid=010400. qla2xxx [0000:03:00.1]-802b:91: BUS RESET SUCCEEDED nexus=91:0:4. qla2xxx [0000:03:00.1]-480b:91: Reset marker scheduled. qla2xxx [0000:03:00.1]-5812:91: Port database changed ffff 0006 0000. qla2xxx [0000:03:00.1]-505f:91: Link is operational (4 Gbps). qla2xxx [0000:03:00.1]-480c:91: Reset marker end. qla2xxx [0000:03:00.1]-480f:91: Loop resync scheduled. qla2xxx [0000:03:00.1]-8837:91: F/W Ready - OK. qla2xxx [0000:03:00.1]-883a:91: fw_state=3 (7, 0, 0, 0) curr time=170b8f315. qla2xxx [0000:03:00.1]-280e:91: HBA in F P2P topology. qla2xxx [0000:03:00.1]-2812:91: qla2x00_configure_hba success qla2xxx [0000:03:00.1]-2814:91: Configure loop -- dpc flags = 0x5260. notice how the 'Port database changed' (8014) arrived after the bus-reset handler completed 'BUS RESET SUCCEEDED'. Now, here's a failing case with the old code (AENs arrive before mailbox-command completion): qla2xxx [0000:03:00.1]-8012:91: BUS RESET ISSUED nexus=91:0:0. qla2xxx [0000:03:00.1]-580e:91: Asynchronous P2P MODE received. qla2xxx [0000:03:00.1]-287d:91: FCPort state transitioned from ONLINE to LOST - portid=010100. qla2xxx [0000:03:00.1]-287d:91: FCPort state transitioned from ONLINE to LOST - portid=010400. qla2xxx [0000:03:00.1]-4800:91: DPC handler sleeping. qla2xxx [0000:03:00.1]-5812:91: Port database changed ffff 0006 0000. qla2xxx [0000:03:00.1]-505f:91: Link is operational (4 Gbps). qla2xxx [0000:03:00.1]-802b:91: BUS RESET SUCCEEDED nexus=91:0:0. qla2xxx [0000:03:00.1]-480b:91: Reset marker scheduled. qla2xxx [0000:03:00.1]-480c:91: Reset marker end. qla2xxx [0000:03:00.1]-480f:91: Loop resync scheduled. qla2xxx [0000:03:00.1]-8837:91: F/W Ready - OK. qla2xxx [0000:03:00.1]-883a:91: fw_state=3 (7, 0, 0, 0) curr time=170be9eb2. qla2xxx [0000:03:00.1]-280e:91: HBA in F P2P topology. qla2xxx [0000:03:00.1]-2812:91: qla2x00_configure_hba success qla2xxx [0000:03:00.1]-2814:91: Configure loop -- dpc flags = 0x5260. qla2xxx [0000:03:00.1]-281e:91: Needs RSCN update and loop transition. qla2xxx [0000:03:00.1]-286a:91: qla2x00_configure_loop *** FAILED ***. qla2xxx [0000:03:00.1]-4810:91: Loop resync end. qla2xxx [0000:03:00.1]-4800:91: DPC handler sleeping. This race would ultimately lead to devices go unexpectedly offline until another link-flap or chip-reset would cause driver re-discovery to take place.

2013-01-30[SCSI] cxgb4i: Remove the scsi host device when removing deviceThadeu Lima de Souza Cascardo
When doing a hotplug remove of a cxgb4 device, there are still dandling symlinks at /sys/class/scsi_host/hostX to the removed PCI device. The upper layer device may also try to send data, which may crash the system. The DETACH message from the lower level driver is sent to the ULD when the device is removed, when the scsi host should be removed from the system, avoiding any problems. After this patch, there are no more dangling symlinks and many attempts to crash the system while there is SCSI activity and removing the device have failed. Adding the device back again works as expected, with the scsi hosts showing up again. Based on a patch by Karen Xie.
