| * | [SCSI] qla2xxx: Don't process RSCNs for a vport on the same physical adapter.Chad Dupuis2013-02-223-18/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently,the driver is processes RSCNs for each new NPIV ports that is created. Processing the RSCN includes a name server query to see what has changed at the name server side. The name server query is performed by the physical port and each virtual port on the physical adapter (since the RSCN is passed to each virtual port for processing). As the number of virtual ports being created increases, this causes a lot of traffic and busies the firmware. Processing the RSCN for a virtual port we already have a priori knowledge of is not necessary so check the 24-bit fabric ID of the RSCN entry and skip processing it if the RSCN is for a virtual port we already know about.

| * | [SCSI] qla2xxx: Correct list-iteration bug in Report-ID Acquisition codes.Andrew Vasquez2013-02-221-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Code in qla24xx_report_id_acquisition() incorrectly assumed that upon completion of list iteration (with no match), the 'pos' (vp) variable passed to list_for_each_entry() would be set to NULL. In this context, if the firmware were to return an unrecognized vp_idx, the follow-on assignments to vp-members could result in corruption of the structure.

| * | [SCSI] qla2xxx: silence two GCC warnings.Paul Bolle2013-02-222-4/+5

(It is not clear to me which array triggers this warning and by how much GCC thinks the subscript is above its bounds. Neither is it clear to me why comparable code in these two functions doesn't trigger this warning.) An easy way to silence these warnings is to use preprocessor macros and strncpy, as that apparently gives GCC enough information to keep track of array bounds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the following error handling for loopback diagnostic mode with ISP83xx: 1. If we do not receive an MBA_DCBX_COMPLETE after our initial set port configuration command, try to reset the port back into normal operation. If that fails, take a FCoE dump and then reset the chip. 2. After completing the loopback diagnostic operation, if the reset of the port back into normal operation fails then reset the port so we take a FCoE dump and then reset the chip. 3. When we receive an IDC notification and the requested operation is loopback extend the loop down timer so the link does not appear to down for an extended period of time.

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'.

| * | [SCSI] qla4xxx: wait for boot target login response during probe.Manish Rangankar2013-01-302-4/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Boot from SAN fails in some cases where boot target login response is slow. In this case, probe finishes early and triggers init, which doesn't find remote disk to mount root which leads to BFS failure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If initialization of adapter fails for some reason, then the interrupt handlers are released. The interrupt handlers are not registered again when initialization of adapter is retried. Solution: Re-register the interrupt handler when adapter initialization is retried.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: QLA4xxx firmware may assert if given more IOCBs than it can handle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The spurious interrupt messages are seen when interrupt lines are shared between different adapters or modules. Example, interrupt lines are shared between qlcnic and qla4xxx and USB modules, then the console is flooded with flurry of spurious interrupt messages which are expected in such scenario. Hence put these messages under debug level 2 for INTx interrupt mode.

| * | [SCSI] cxgb4i: Remove the scsi host device when removing deviceThadeu Lima de Souza Cascardo2013-01-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
