2017-03-07scsi: storvsc: Workaround for virtual DVD SCSI versionStephen Hemminger1-10/+17
Hyper-V host emulation of SCSI for virtual DVD device reports SCSI version 0 (UNKNOWN) but is still capable of supporting REPORTLUN. Without this patch, a GEN2 Linux guest on Hyper-V will not boot 4.11 successfully with virtual DVD ROM device. What happens is that the SCSI scan process falls back to doing sequential probing by INQUIRY. But the storvsc driver has a previous workaround that masks/blocks all errors reports from INQUIRY (or MODE_SENSE) commands. This workaround causes the scan to then populate a full set of bogus LUN's on the target and then sends kernel spinning off into a death spiral doing block reads on the non-existent LUNs. By setting the correct blacklist flags, the target with the DVD device is scanned with REPORTLUN and that works correctly. Patch needs to go in current 4.11, it is safe but not necessary in older kernels. Signed-off-by: Stephen Hemminger <sthemmin@microsoft.com> Reviewed-by: K. Y.

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.

2017-03-03sfc: avoid max() in array sizeEdward Cree1-5/+5
It confuses sparse, which thinks the size isn't constant. Let's achieve the same thing with a BUILD_BUG_ON, since we know which one should be bigger and don't expect them ever to change. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-03-03rds: remove unnecessary returned value checkZhu Yanjun4-14/+4
The function rds_trans_register always returns 0. As such, it is not necessary to check the returned value.

2017-03-03rxrpc: Fix potential NULL-pointer exceptionDavid Howells1-7/+8
Fix a potential NULL-pointer exception in rxrpc_do_sendmsg(). The call state check that I added should have gone into the else-body of the if-statement where we actually have a call to check. Found by CoverityScan CID#1414316 ("Dereference after null check").

2017-03-03nfp: correct DMA direction in XDP DMA syncJakub Kicinski1-2/+2
dma_sync_single_for_*() takes the direction in which the buffer was mapped, not the direction of the sync. We should sync XDP buffers bidirectionally.

2017-03-03nfp: don't tell FW about the reserved buffer spaceJakub Kicinski1-1/+2
Since commit c0f031bc8866 ("nfp_net: use alloc_frag() and build_skb()") we are allocating buffers which have to hold both the data and skb to be created in place by build_skb(). FW should only be told about the buffer space it can DMA to, that is without the build_skb() headroom and tailroom. Note: firmware applications should validate the buffers against both MTU and free list buffer size so oversized packets would not pass through the NIC anyway.
