2017-03-06scsi: lpfc: add transport eh_timed_out referenceJames Smart1-0/+1
Christoph's prior patch missed the template for the sli3 adapters, which is now the "no host reset" template.

2017-03-06scsi: lpfc: Fix eh_deadline setting for sli3 adapters.James Smart5-6/+69
A previous change unilaterally removed the hba reset entry point from the sli3 host template. This was done to allow tape devices being used for back up from being removed. Why was this done ? When there was non-responding device on the fabric, the error escalation policy would escalate to the reset handler. When the reset handler was called, it would reset the adapter, dropping link, thus logging out and terminating all i/o's - on any target. If there was a tape device on the same adapter that wasn't in error, it would kill the tape i/o's, effectively killing the tape device state. With the reset point removed, the adapter reset avoided the fabric logout, allowing the other devices to continue to operate unaffected. A hack - yes. Hint: we really need a transport I_T nexus reset callback added to the eh process (in between the SCSI target reset and hba reset points), so a fc logout could occur to the one bad target only and stop the error escalation process. This patch commonizes the approach so it can be used for sli3 and sli4 adapters, but mandates the admin, via module parameter, specifically identify which adapters the resets are to be removed for. Additionally, bus_reset, which sends Target Reset TMFs to all targets, is also removed from the template as it too has the same effect as the adapter reset.

2017-03-06scsi: lpfc: replace init_timer by setup_timerTomas Jasek2-33/+19
This patch shortens every init_timer in lpfc module followed by function and data assignment using setup_timer. This is purely cleanup patch, it does not add new functionality nor remove any existing functionality. An init_timer call in this form: init_timer(&vport->fc_disctmo); vport->fc_disctmo.function = lpfc_disc_timeout; vport->fc_disctmo.data = vport; is shortened to: setup_timer(&vport->fc_disctmo, lpfc_disc_timeout, vport); It increases readability and reduces chances of mistakes done by developers.

2017-03-01scsi: mpt3sas: Avoid sleeping in interrupt contextBart Van Assche5-12/+16
Commit 669f044170d8 ("scsi: srp_transport: Move queuecommand() wait code to SCSI core") can make scsi_internal_device_block() sleep. However, the mpt3sas driver can call this function from an interrupt handler. Hence add a second argument to scsi_internal_device_block() that restores the old behavior of this function for the mpt3sas handler. The call chain that triggered an "IRQ handler enabled interrupts" complaint is as follows: _base_interrupt() -> _base_async_event() -> mpt3sas_scsih_event_callback() -> _scsih_check_topo_delete_events() -> _scsih_block_io_to_children_attached_directly() -> _scsih_block_io_device() -> _scsih_internal_device_block() -> scsi_internal_device_block() Reported-by: Omar Sandoval <osandov@osandov.com> Signed-off-by: Bart Van Assche <bart.vanassche@sandisk.com> Cc: Omar Sandoval <osandov@osandov.com> Cc: Hannes Reinecke <hare@suse.com> Cc: Sagi Grimberg <sagi@grimberg.me> Cc: Christoph Hellwig <hch@lst.de> Cc: Sathya Prakash <sathya.prakash@broadcom.com> Cc: Chaitra P B <chaitra.basappa@broadcom.com> Cc: Suganath Prabu Subramani <suganath-prabu.subramani@broadcom.com> Cc: Sreekanth Reddy <Sreekanth.Reddy@broadcom.com> Cc: <stable@vger.kernel.org> # v4.10+ Tested-by: Omar Sandoval <osandov@fb.com> Signed-off-by: Martin K.

2017-03-01scsi: sd: Check for unaligned partial completionDamien Le Moal2-15/+17
Commit <f2e767bb5d6e> ("mpt3sas: Force request partial completion alignment") was not considering the case of commands not operating on logical block size units (e.g. REQ_OP_ZONE_REPORT and its 64B aligned partial replies). In this case, forcing alignment of resid to the device logical block size can break the command result, e.g. in the case of REQ_OP_ZONE_REPORT, the exact number of zone reported by the device. Move the partial completion alignement check of mpt3sas to a generic implementation in sd_done(). The check is added within the default section of the initial req_op() switch case so that the report and reset zone commands are ignored. In addition, as sd_done() is not called for passthrough requests, resid corrections are not done as intended by the initial mpt3sas patch.

2017-02-28scsi: libiscsi: add lock around task lists to fix list corruption regressionChris Leech2-1/+26
There's a rather long standing regression from the commit "libiscsi: Reduce locking contention in fast path" Depending on iSCSI target behavior, it's possible to hit the case in iscsi_complete_task where the task is still on a pending list (!list_empty(&task->running)). When that happens the task is removed from the list while holding the session back_lock, but other task list modification occur under the frwd_lock. That leads to linked list corruption and eventually a panicked system. Rather than back out the session lock split entirely, in order to try and keep some of the performance gains this patch adds another lock to maintain the task lists integrity. Major enterprise supported kernels have been backing out the lock split for while now, thanks to the efforts at IBM where a lab setup has the most reliable reproducer I've seen on this issue. This patch has been tested there successfully.

2017-02-22scsi: qedf: Add QLogic FastLinQ offload FCoE driver framework.Dupuis, Chad16-0/+8816
The QLogic FastLinQ Driver for FCoE (qedf) is the FCoE specific module for 41000 Series Converged Network Adapters by QLogic. This patch consists of following changes: - MAINTAINERS Makefile and Kconfig changes for qedf - PCI driver registration - libfc/fcoe host level initialization - SCSI host template initialization and callbacks - Debugfs and log level infrastructure - Link handling - Firmware interface structures - QED core module initialization - Light L2 interface callbacks - I/O request initialization - Firmware I/O completion handling - Firmware ELS request/response handling - FIP request/response handled by the driver itself Signed-off-by: Nilesh Javali <nilesh.javali@cavium.com> Signed-off-by: Manish Rangankar <manish.rangankar@cavium.com> Signed-off-by: Saurav Kashyap <saurav.kashyap@cavium.com> Signed-off-by: Arun Easi <arun.easi@cavium.com> Signed-off-by: Chad Dupuis <chad.dupuis@cavium.com> Signed-off-by: Martin K.

2017-02-22scsi: qla2xxx: Cleaned up queue configuration code.Michael Hernandez1-9/+4
This patch cleaned up queue configuration code, such that once initialized, we should not touch msix_count value. This will prevent incorrect numbers of MSI-X vectors requested while performing target mode configuration.
