If bnx2fc_allocate_hash_table() for some reasons fails, it is possible that the hash_tbl_segments or the hash_tbl_pbl pointers are NULL. In this case bnx2fc_free_hash_table() will panic the system. this patch also fixes a memory leak, the hash_tbl_segments pointer was never freed. Signed-off-by:

Access to tgt->req_vq is strictly serialized by spin_lock of tgt->tgt_lock, so the ACCESS_ONCE() isn't necessary. smp_read_barrier_depends() in virtscsi_req_done was introduced to order reading req_vq and decreasing tgt->reqs, but it isn't needed now because req_vq is read from scsi->req_vqs[vq->index - VIRTIO_SCSI_VQ_BASE] instead of tgt->req_vq, so remove the unnecessary barrier. Also remove related comment about the barrier. Signed-off-by:

Add a memory barrier to ensure the valid bit is read before any of the cqe payload is read. This fixes an issue seen on Power where the cqe payload was getting loaded before the valid bit. When this occurred, we saw an iotag out of range error when a command completed, but since the iotag looked invalid the command didn't get completed to scsi core. Later we hit the command timeout, attempted to abort the command, then waited for the aborted command to get returned. Since the adapter already returned the command, we timeout waiting, and end up escalating EEH all the way to host reset. This patch fixes this issue. Signed-off-by:

[Resend of earlier patch - added equivalent changes to sun3 NCR5380 code] The abort/reset lowlevel return codes had changed with the new error SCSI handling - update Atari and Sun3 NCR5380 drivers to reflect this. Change reset handling for Atari to clear queues only, do not attempt to call done() on each command aborted by the reset. The EH code should do that for us. Queues _must_ be cleared, otherwise atari_scsi_bus_reset will not release the ST-DMA lock, deadlocking further error recovery. Update the Sun3 NCR5380 driver as well - the Sun3 driver was derived from the Atari one. Kudos to Finn Thain for the Sun3 part and cleaning up the header files. After the header cleanup, the initio.h include (!) can be dropped from sun3_scsi.h now. Signed-off-by:

bfa_fcb_pbc_vport_create() is called only from bfa_fcs_pbc_vport_init(), that is called only from bfad_drv_start() with bfad_lock spinlock held. So the patch replaces GFP_KERNEL with GFP_ATOMIC to avoid sleeping in atomic spinlock context. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

Fnic Ctlr Path Trace utility is a tracing functionality built directly into fnic driver to trace the control path frames like discovery, FLOGI request/reply, PLOGI request/reply, link event etc. It will be one trace file for all fnics. It will help us to debug and resolve the discovery and initialization related issues in more convenient way. This trace information includes time stamp, Host Number, Frame type, Frame Length and Frame. By default,64 pages are allocated but we can change the number of allocated pages by module parameter fnic_fc_trace_max_page. Each entry is of 256 byte and available entries are depends on allocated number of pages. We can turn on or off the fnic control path trace functionality by module paramter fc_trace_enable and/or reset the trace contain by module paramter fc_trace_clear. Signed-off-by:

This patch contains following three minor fixes. 1) During Probe, fnic was sending FIP solicitation in Non FIP mode which is not expected, setting the internal fip state to Non FIP mode explicitly, avoids sending FIP frame. 2) When target goes offline, all outstanding IOs belong to the target will be terminated by driver, If the termination count is high, then it influences firmware responsiveness. To improve the responsiveness, default IO throttle count is reduced to 256. 3) Accessing Virtual Fabric Id (vfid) and fc_map of Fibre-Channel Forwarder(FCF) is invalid in fnic driver when Clear Virtual Link(CVL) is received prior to receiving flogi reject from switch. As CVL clears all FCFs. Signed-off-by:
