c0e01eac7a mlxsw: spectrum: Avoid possible NULL pointer dereference
In case we got an FDB notification for a port that doesn't exist we
execute an FDB entry delete to prevent it from re-appearing the next
time we poll for notifications.

If the operation failed we would trigger a NULL pointer dereference as
'mlxsw_sp_port' is NULL.

Fix it by reporting the error using the underlying bus device instead.

b7ce520e9f sh_eth: Do not print an error message for probe deferral
EPROBE_DEFER is not an error, hence printing an error message like

    sh-eth ee700000.ethernet: failed to initialise MDIO

may confuse the user.

To fix this, suppress the error message in case of probe deferral.
While at it, shorten the message, and add the actual error code.

b18e5e86b4 ldmvsw: unregistering netdev before disable hardware
When running LDom binding/unbinding test, kernel may panic
in ldmvsw_open(). It is more likely that because we're removing
the ldc connection before unregistering the netdev in vsw_port_remove(),
we set up a window of time where one process could be removing the
device while another trying to UP the device. This also sometimes causes
vio handshake error due to opening a device without closing it completely.
We should unregister the netdev before we disable the "hardware".

d2be3667f3 ethernet: aquantia: remove redundant checks on error status
The error status err is initialized as zero and then being checked
several times to see if it is less than zero even when it has not
been updated.  It may seem that the err should be assigned to the
return code of the call to the various *offload_en_set calls and
then we check for failure, however, these functions are void and
never actually return any status.

Since these error checks are redundant we can remove these
as well as err and the error exit label err_exit.

Merge tag 'hwparam-20170420' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull hw lockdown support from David Howells:
 "Annotation of module parameters that configure hardware resources
  including ioports, iomem addresses, irq lines and dma channels.

  This allows a future patch to prohibit the use of such module
  parameters to prevent that hardware from being abused to gain access
  to the running kernel image as part of locking the kernel down under
  UEFI secure boot conditions.

  Annotations are made by changing:

        module_param(n, t, p)
        module_param_named(n, v, t, p)
        module_param_array(n, t, m, p)

  to:

        module_param_hw(n, t, hwtype, p)
        module_param_hw_named(n, v, t, hwtype, p)
        module_param_hw_array(n, t, hwtype, m, p)

  where the module parameter refers to a hardware setting

  hwtype specifies the type of the resource being configured. This can
  be one of:

        ioport          Module parameter configures an I/O port
        iomem           Module parameter configures an I/O mem address
        ioport_or_iomem Module parameter could be either (runtime set)
        irq             Module parameter configures an I/O port
        dma             Module parameter configures a DMA channel
        dma_addr        Module parameter configures a DMA buffer address
        other           Module parameter configures some other value

  Note that the hwtype is compile checked, but not currently stored (the
  lockdown code probably won't require it). It is, however, there for
  future use.

  A bonus is that the hwtype can also be used for grepping.

  The intention is for the kernel to ignore or reject attempts to set
  annotated module parameters if lockdown is enabled. This applies to
  options passed on the boot command line, passed to insmod/modprobe or
  direct twiddling in /sys/module/ parameter files.

  The module initialisation then needs to handle the parameter not being
  set, by (1) giving an error, (2) probing for a value or (3) using a
  reasonable default.

  What I can't do is just reject a module out of hand because it may
  take a hardware setting in the module parameters. Some important
  modules, some ipmi stuff for instance, both probe for hardware and
  allow hardware to be manually specified; if the driver is aborts with
  any error, you don't get any ipmi hardware.

  Further, trying to do this entirely in the module initialisation code
  doesn't protect against sysfs twiddling.

  [!] Note that in and of itself, this series of patches should have no
      effect on the the size of the kernel or code execution - that is
      left to a patch in the next series to effect. It does mark
      annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in
      an already existing field"

be47c55557 qede: Split PF/VF ndos.
PFs and VFs share the same structure of NDOs today,
and the VFs explicitly fails the ndo_xdp() callback stating
it doesn't support XDP.

This results in lots of:

  [qede_xdp:1032(enp131s2)]VFs don't support XDP
  ------------[ cut here ]------------
  WARNING: CPU: 4 PID: 1426 at net/core/rtnetlink.c:1637 rtnl_dump_ifinfo+0x354/0x3c0

    sock_recvmsg+0x3d/0x50
  ...

As every dump request for the VF interface info would fail due to
rtnl_xdp_fill() returning an error code.

To resolve this, introduce a subset of the NDOs meant for the VF
in a seperate structure and register that one instead for VFs,
and omit the ndo_xdp initialization.

83bd5118a1 net/mlx4_core: Reduce harmless SRIOV error message to debug level
Under SRIOV resource management, extra counters are allocated to VFs
from a free pool. If that pool is empty, the ALLOC_RES command for
a counter resource fails -- and this generates a misleading error
message in the message log.

Under SRIOV, each VF is allocated (i.e., guaranteed) 2 counters --
one counter per port. For ETH ports, the RoCE driver requests an
additional counter (above the guaranteed counters). If that request
fails, the VF RoCE driver simply uses the default (i.e., guaranteed)
counter for that port.

Thus, failing to allocate an additional counter does not constitute
a  problem, and the error message on the PF when this occurs should
be reduced to debug level.

Finally, to identify the situation that the reason for the failure is
that no resources are available to grant to the VF, we modified the
error returned by mlx4_grant_resource to -EDQUOT (Quota exceeded),
which more accurately describes the error.

  The second tag contains the patch series from Intel plus three other

063246641d format-security: move static strings to const
While examining output from trial builds with -Wformat-security enabled,
many strings were found that should be defined as "const", or as a char
array instead of char pointer.  This makes some static analysis easier,
by producing fewer false positives.

As these are all trivial changes, it seemed best to put them all in a
single patch rather than chopping them up per maintainer.

752ade68cb treewide: use kv[mz]alloc* rather than opencoded variants
There are many code paths opencoding kvmalloc.  Let's use the helper
instead.  The main difference to kvmalloc is that those users are
usually not considering all the aspects of the memory allocator.  E.g.
allocation requests <= 32kB (with 4kB pages) are basically never failing
and invoke OOM killer to satisfy the allocation.  This sounds too
disruptive for something that has a reasonable fallback - the vmalloc.
On the other hand those requests might fallback to vmalloc even when the
memory allocator would succeed after several more reclaim/compaction
attempts previously.  There is no guarantee something like that happens
though.

This patch converts many of those places to kv[mz]alloc* helpers because
they are more conservative.

48f5bccc60 net: ethernet: ti: cpsw: adjust cpsw fifos depth for fullduplex flow control
When users set flow control using ethtool the bits are set properly in the
CPGMAC_SL MACCONTROL register, but the FIFO depth in the respective Port n
Maximum FIFO Blocks (Pn_MAX_BLKS) registers remains set to the minimum size
reset value. When receive flow control is enabled on a port, the port's
associated FIFO block allocation must be adjusted. The port RX allocation
must increase to accommodate the flow control runout. The TRM recommends
numbers of 5 or 6.

Hence, apply required Port FIFO configuration to
Pn_MAX_BLKS.Pn_TX_MAX_BLKS=0xF and Pn_MAX_BLKS.Pn_RX_MAX_BLKS=0x5 during
interface initialization.
