| | * | [SCSI] isci: Allow SSP tasks into the task management path.Jeff Skirvin2012-09-241-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit fixes a driver bug for SSP tasks that require task management in the target after they complete in the SCU hardware. The problem was manifested in the function "isci_task_abort_task", which tests to see if the sas_task.lldd_task is non-NULL before allowing task management; this bug would always NULL lldd_task in the SCU I/O completion path even if target management was required, which would prevent task / target manangement from happening. Note that in the case of SATA/STP targets, error recovery is provided by the libata error handler which is why SATA/STP device recovery worked correctly even though SSP handling did not.

| | * | [SCSI] zfcp: only access zfcp_scsi_dev for valid scsi_deviceMartin Peschke2012-09-241-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __scsi_remove_device (e.g. due to dev_loss_tmo) calls zfcp_scsi_slave_destroy which in turn sends a close LUN FSF request to the adapter. After 30 seconds without response, zfcp_erp_timeout_handler kicks the ERP thread failing the close LUN ERP action. zfcp_erp_wait in zfcp_erp_lun_shutdown_wait and thus zfcp_scsi_slave_destroy returns and then scsi_device is no longer valid. Sometime later the response to the close LUN FSF request may finally come in. However, commit b62a8d9b45b971a67a0f8413338c230e3117dff5 "[SCSI] zfcp: Use SCSI device data zfcp_scsi_dev instead of zfcp_unit" introduced a number of attempts to unconditionally access struct zfcp_scsi_dev through struct scsi_device causing a use-after-free. This leads to an Oops due to kernel page fault in one of: zfcp_fsf_abort_fcp_command_handler, zfcp_fsf_open_lun_handler, zfcp_fsf_close_lun_handler, zfcp_fsf_req_trace, zfcp_fsf_fcp_handler_common. Move dereferencing of zfcp private data zfcp_scsi_dev allocated in scsi_device via scsi_transport_reserve_device after the check for potentially aborted FSF request and thus no longer valid scsi_device. Only then assign sdev_to_zfcp(sdev) to the local auto variable struct zfcp_scsi_dev *zfcp_sdev.

| | * | [SCSI] zfcp: No automatic port_rescan on eventsSteffen Maier2012-09-245-4/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In FC fabrics with large zones, the automatic port_rescan on incoming ELS and any adapter recovery can cause quite some traffic at the very same time, especially if lots of Linux images share an HBA, which is common on s390. This can cause trouble and failures. Fix this by making such port rescans dependent on a user configurable module parameter. The following unconditional automatic port rescans remain as is: On setting an adapter online and on manual user-triggered writes to the sysfs attribute port_rescan.

Even remote ports in use can be removed causing unreachable garbage objects zfcp_ports with zfcp_units. Thus units won't come back even after a manual port_rescan. The kref of zfcp_port->dev.kobj is already used by the driver core. We cannot re-use it to track the number of zfcp_units. Re-introduce our own counter for units per port and check on port_remove.

| | * | [SCSI] zfcp: Do not wakeup while suspendedSteffen Maier2012-09-245-10/+86

During resume, zfcp gets callbacks from cio regarding the modified subchannels but they can be arbitrarily mixed with the restore/resume callback. Since the cio callbacks would trigger adapter recovery, zfcp could wakeup before the resume callback. Therefore, ignore the cio callbacks regarding subchannels while being suspended. We can safely do so, since zfcp does not deal itself with subchannels. For problem determination purposes, we still trace the ignored callback events. The following kernel messages could be seen on resume: kernel: <WWPN>: parent <FCP device bus ID> should not be sleeping As part of adapter reopen recovery, zfcp performs auto port scanning which can erroneously try to register new remote ports with scsi_transport_fc and the device core code complains about the parent (adapter) still sleeping. kernel: zfcp.3dff9c: <FCP device bus ID>:\ Setting up the QDIO connection to the FCP adapter failed <last kernel message repeated 3 more times> kernel: zfcp.574d43: <FCP device bus ID>:\ ERP cannot recover an error on the FCP device In such cases, the adapter gave up recovery and remained blocked along with its child objects: remote ports and LUNs/scsi devices. Even the adapter shutdown as part of giving up recovery failed because the ccw device state remained disconnected. Later, the corresponding remote ports ran into dev_loss_tmo. As a result, the LUNs were erroneously not available again after resume. Even a manually triggered adapter recovery (e.g. sysfs attribute failed, or device offline/online via sysfs) could not recover the adapter due to the remaining disconnected state of the corresponding ccw device.

For maximum sized requests, payload->counter == scount after the last loop iteration. Therefore, do bounds checking first (with boolean shortcut) to not access the invalid element pl[scount]. Do not trust the maximum sbale->scount value from the HBA but ensure we won't access the pl vector out of our allocated bounds. While at it, clean up scoping and prevent unnecessary memset.
