458bf2f224 net: core: support XDP generic on stacked devices.
When a device is stacked like (team, bonding, failsafe or netvsc) the
XDP generic program for the parent device was not called.

Move the call to XDP generic inside __netif_receive_skb_core where
it can be done multiple times for stacked case.

996ed04741 netvsc: unshare skb in VF rx handler
The netvsc VF skb handler should make sure that skb is not
shared. Similar logic already exists in bonding and team device
drivers.

This is not an issue in practice because the VF devicex
does not send up shared skb's. But the netvsc driver
should do the right thing if it did.

f2696099c6 udp: Avoid post-GRO UDP checksum recalculation
Currently, when resegmenting an unexpected UDP GRO packet, the full UDP
checksum will be calculated for every new SKB created by skb_segment()
because the netdev features passed in by udp_rcv_segment() lack any
information about checksum offload capabilities.

Usually, we have no need to perform this calculation again, as
  1) The GRO implementation guarantees that any packets making it to the
     udp_rcv_segment() function had correct checksums, and, more
     importantly,
  2) Upon the successful return of udp_rcv_segment(), we immediately pull
     the UDP header off and either queue the segment to the socket or
     hand it off to a new protocol handler.

Unless userspace has set the IP_CHECKSUM sockopt to indicate that they
want the final checksum values, we can pass the needed netdev feature
flags to __skb_gso_segment() to avoid checksumming each segment in
skb_segment().

d724c9e549 KVM: PPC: Book3S HV: Restore SPRG3 in kvmhv_p9_guest_entry()
The sprgs are a set of 4 general purpose sprs provided for software use.
SPRG3 is special in that it can also be read from userspace. Thus it is
used on linux to store the cpu and numa id of the process to speed up
syscall access to this information.

This register is overwritten with the guest value on kvm guest entry,
and so needs to be restored on exit again. Thus restore the value on
the guest exit path in kvmhv_p9_guest_entry().

Commit 3309bec85e ("KVM: PPC: Book3S HV: Fix lockdep warning when
entering the guest") moved calls to trace_hardirqs_{on,off} in the
entry path used for HPT guests.  Similar code exists in the new
streamlined entry path used for radix guests on POWER9.  This makes
the same change there, so as to avoid lockdep warnings such as this:

bcaa3110d5 KVM: PPC: Book3S HV: XIVE: Fix page offset when clearing ESB pages
Under XIVE, the ESB pages of an interrupt are used for interrupt
management (EOI) and triggering. They are made available to guests
through a mapping of the XIVE KVM device.

When a device is passed-through, the passthru_irq helpers,
kvmppc_xive_set_mapped() and kvmppc_xive_clr_mapped(), clear the ESB
pages of the guest IRQ number being mapped and let the VM fault
handler repopulate with the correct page.

The ESB pages are mapped at offset 4 (KVM_XIVE_ESB_PAGE_OFFSET) in the
KVM device mapping. Unfortunately, this offset was not taken into
account when clearing the pages. This lead to issues with the
passthrough devices for which the interrupts were not functional under
some guest configuration (tg3 and single CPU) or in any configuration
(e1000e adapter).

aedb5b1942 KVM: PPC: Book3S HV: XIVE: Take the srcu read lock when accessing memslots
According to Documentation/virtual/kvm/locking.txt, the srcu read lock
should be taken when accessing the memslots of the VM. The XIVE KVM
device needs to do so when configuring the page of the OS event queue
of vCPU for a given priority and when marking the same page dirty
before migration.

This avoids warnings such as :

ef97402040 KVM: PPC: Book3S HV: XIVE: Do not clear IRQ data of passthrough interrupts
The passthrough interrupts are defined at the host level and their IRQ
data should not be cleared unless specifically deconfigured (shutdown)
by the host. They differ from the IPI interrupts which are allocated
by the XIVE KVM device and reserved to the guest usage only.

This fixes a host crash when destroying a VM in which a PCI adapter
was passed-through. In this case, the interrupt is cleared and freed
by the KVM device and then shutdown by vfio at the host level.

7e10b9a6da KVM: PPC: Book3S HV: XIVE: Introduce a new mutex for the XIVE device
The XICS-on-XIVE KVM device needs to allocate XIVE event queues when a
priority is used by the OS. This is referred as EQ provisioning and it
is done under the hood when :

  1. a CPU is hot-plugged in the VM
  2. the "set-xive" is called at VM startup
  3. sources are restored at VM restore

The kvm->lock mutex is used to protect the different XIVE structures
being modified but in some contexts, kvm->lock is taken under the
vcpu->mutex which is not permitted by the KVM locking rules.

Introduce a new mutex 'lock' for the KVM devices for them to
synchronize accesses to the XIVE device structures.

04cf8b32bc scsi: libsas: only clear phy->in_shutdown after shutdown event done
When the event queue is full of phy up and down events and reached the
threshold, we will queue a shutdown-event, and set phy->in_shutdown so that
we will not queue a shutdown-event again. But before the shutdown-event can
be executed, every phy-down event will clear
phy->in_shutdown and a new shutdown-event will be queued. The queue will
be full of these shutdown-events.

Fix this by only clear phy->in_shutdown in sas_phye_shutdown(), that is
after the first shutdown-event has been executed.

1d94f06e7f scsi: smartpqi: properly set both the DMA mask and the coherent DMA mask
When SME is enabled, the smartpqi driver won't work on the HP DL385 G10
machine, which causes the failure of kernel boot because it fails to
allocate pqi error buffer. Please refer to the kernel log:

Basically, the fact that the coherent DMA mask value wasn't set caused the
driver to fall back to SWIOTLB when SME is active.

For correct operation, lets call the dma_set_mask_and_coherent() to
properly set the mask for both streaming and coherent, in order to inform
the kernel about the devices DMA addressing capabilities.

ef4021fe5f scsi: zfcp: fix to prevent port_remove with pure auto scan LUNs (only sdevs)
When the user tries to remove a zfcp port via sysfs, we only rejected it if
there are zfcp unit children under the port. With purely automatically
scanned LUNs there are no zfcp units but only SCSI devices. In such cases,
the port_remove erroneously continued. We close the port and this
implicitly closes all LUNs under the port. The SCSI devices survive with
their private zfcp_scsi_dev still holding a reference to the "removed"
zfcp_port (still allocated but invisible in sysfs) [zfcp_get_port_by_wwpn
in zfcp_scsi_slave_alloc]. This is not a problem as long as the fc_rport
stays blocked. Once (auto) port scan brings back the removed port, we
unblock its fc_rport again by design.  However, there is no mechanism that
would recover (open) the LUNs under the port (no "ersfs_3" without
zfcp_unit [zfcp_erp_strategy_followup_success]).  Any pending or new I/O to
such LUN leads to repeated:

  Done: NEEDS_RETRY Result: hostbyte=DID_IMM_RETRY driverbyte=DRIVER_OK

See also v4.10 commit 6f2ce1c6af ("scsi: zfcp: fix rport unblock race
with LUN recovery"). Even a manual LUN recovery
(echo 0 > /sys/bus/scsi/devices/H:C:T:L/zfcp_failed)
does not help, as the LUN links to the old "removed" port which remains
to lack ZFCP_STATUS_COMMON_RUNNING [zfcp_erp_required_act].
The only workaround is to first ensure that the fc_rport is blocked
(e.g. port_remove again in case it was re-discovered by (auto) port scan),
then delete the SCSI devices, and finally re-discover by (auto) port scan.
The port scan includes an fc_rport unblock, which in turn triggers
a new scan on the scsi target to freshly get new pure auto scan LUNs.

Fix this by rejecting port_remove also if there are SCSI devices
(even without any zfcp_unit) under this port. Re-use mechanics from v3.7
commit d99b601b63 ("[SCSI] zfcp: restore refcount check on port_remove").
However, we have to give up zfcp_sysfs_port_units_mutex earlier in unit_add
to prevent a deadlock with scsi_host scan taking shost->scan_mutex first
and then zfcp_sysfs_port_units_mutex now in our zfcp_scsi_slave_alloc().
