net: vrf: Fix ipv6 source address selection
IPv6 address selection is currently messed up for several use cases such
as unnumbered deployments with global addresses on the VRF device and none
on the enslaved devices.
Update the source address selection to consider the real output route as
opposed to the VRF route that sends packets to the VRF device first (ie.,
implement get_saddr6 similar to the IPv4 method) and update the IPv6
address selection to consider L3 domains and preference for addresses on
the VRF device).

IPv6 version of 3f2fb9a834cb ("net: l3mdev: address selection should only
consider devices in L3 domain") and the follow up commit, a17b693cdd876
("net: l3mdev: prefer VRF master for source address selection").
That is, if outbound device is given then the address preference order
is an address from that device, an address from the master device if it
is enslaved, and then an address from a device in the same L3 domain.

IPv6 source address selection needs to consider the real egress route.
Similar to IPv4 implement a get_saddr6 method which is called if
source address has not been set. The get_saddr6 method does a full
lookup which means pulling a route from the VRF FIB table and properly
considering linklocal/multicast destination addresses. Lookup failures
(eg., unreachable) then cause the source address selection to fail
which gets propagated back to the caller.

VRF driver needs access to ip6_route_get_saddr code. Since it does
little beyond ipv6_dev_get_saddr and ipv6_dev_get_saddr is already
exported for modules move ip6_route_get_saddr to the header as an
inline.

The inline isa_register_driver stub simply allows compilation on systems
with CONFIG_ISA disabled; the dummy isa_register_driver does not
register an isa_driver at all. The inline isa_register_driver should
return -ENODEV to indicate lack of support when attempting to register
an isa_driver on such a system with CONFIG_ISA disabled.

The isa_bus_init function must be called before drivers which utilize
the ISA bus driver are registered. A race condition for initilization
exists if device_initcall is used (the isa_bus_init callback is placed
in the same initcall level as dependent drivers which use module_init).
This patch ensures that isa_bus_init is called first by utilizing
postcore_initcall in favor of device_initcall.

====================
Future-proof tunnel offload handlers
These patches are meant to address two things. First we are currently
using the ndo_add/del_vxlan_port calls with VXLAN-GPE tunnels and we
cannot really support that as it is likely to cause more harm than
good since VXLAN-GPE can support tunnels without a MAC address on the
inner header.
As such we need to add a new offload to advertise this, but in doing so it
would mean introducing 3 new functions for the driver to request the ports,
and then for the tunnel to push the changes to add and delete the ports to
the device. However instead of taking that approach I think it would be
much better if we just made one common function for fetching the ports, and
provided a generic means to push the tunnels to the device. So in order to
make this work this patch set does several things.
First it merges the existing VXLAN and GENEVE functionality into one set of
functions and passes an enum in order to specify the type of tunnel we want
to offload. By doing this we only have to extend this enum in the future
if we want to add additional types.
Second it goes through the drivers replacing all of the tunnel specific
offload calls with implementations that support the generic calls so that
we can drop the VXLAN and GENEVE specific calls entirely.
Finally I go through in the last patch and replace the VXLAN specific
offload request that was being used for VXLAN-GPE with one that specifies
if we want to offload VXLAN or VXLAN-GPE so that the hardware can decide if
it can actually support it or not.
I also ended up with some minor clean-up built into the driver patches for
this. Most of it is to either fix misuse of build flags, specifying a type
to ignore instead of the type that should be used, or in the case of ixgbe
I actually moved a rtnl_lock/unlock in order to avoid taking it unless it
was actually needed.
v2:
I did my best to remove the word "offload" from any of the calls or
notifiers as this isn't really an offload. It
is a workaround for the fact that the drivers don't provide basic features
like CHECKSUM_COMPLETE. I also added a disclaimer to the section defining
the function prototypes explaining that these are essentially workarounds.
I ended up going through and stripping all of the VXLAN and GENEVE build
flags from the drivers. There isn't much point in carrying them. In
addition I dropped the use of the vxlan.h or geneve.h header files in favor
of udp_tunnel.h in the cases where a driver didn't need anything from
either of those headers.
I updated the tunnel add/del functions so that they pass a udp_tunnel_info
structure instead of a list of arguments. This way we should be able to
add additional information in the future with little impact on the other
drivers.
I updated bnxt so that it doesn't use a hard-coded port number for GENEVE.
I have been able to test mlx4e, mlx5e, and i40e and verified functionality
on these drivers. Though there are patches for the net tree I submitted
due to unrelated bugs I found in the mlx4e and i40e/i40evf drivers.
v3:
Fixed a typo that caused us to add geneve port when we should have been
deleting it.
Ended up dropping geneve and vxlan wrappers for
udp_tunnel_notify_rx_add/del_port and instead just called them directly.
Updated comments for functions to call out RTNL instead of port lock.
Updated patch description to remove changes that were moved into a second
patch.
Rebased on latest net-next to fix merge conflict on bnxt driver.

The fact is VXLAN with Generic Protocol Extensions cannot be supported by
the same hardware parsers that support VXLAN. The protocol extensions
allow for things like a Next Protocol field which in turn allows for things
other than Ethernet to be passed over the tunnel. Most existing parsers
will not know how to interpret this.
To resolve this I am giving VXLAN-GPE its own UDP encapsulation offload
type. This way hardware that does support GPE can simply add this type to
the switch statement for VXLAN, and if they don't support it then this will
fix any issues where headers might be interpreted incorrectly.

This patch merges the notifiers for VXLAN and GENEVE into a single UDP
tunnel notifier. The idea is that we will want to only have to make one
notifier call to receive the list of ports for VXLAN and GENEVE tunnels
that need to be offloaded.
In addition we add a new set of ndo functions named ndo_udp_tunnel_add and
ndo_udp_tunnel_del that are meant to allow us to track the tunnel meta-data
such as port and address family as tunnels are added and removed. The
tunnel meta-data is now transported in a structure named udp_tunnel_info
which for now carries the type, address family, and port number. In the
future this could be updated so that we can include a tuple of values
including things such as the destination IP address and other fields.
I also ended up going with a naming scheme that consisted of using the
prefix udp_tunnel on function names. I applied this to the notifier and
ndo ops as well so that it hopefully points to the fact that these are
primarily used in the udp_tunnel functions.

Several modern devices, such as PC/104 cards, are expected to run on
modern systems via an ISA bus interface. Since ISA is a legacy interface
for most modern architectures, ISA support should remain disabled in
general. Support for ISA-style drivers should be enabled on a per driver
basis.
To allow ISA-style drivers on modern systems, this patch introduces the
ISA_BUS_API and ISA_BUS Kconfig options. The ISA bus driver will now
build conditionally on the ISA_BUS_API Kconfig option, which defaults to
the legacy ISA Kconfig option. The ISA_BUS Kconfig option allows the
ISA_BUS_API Kconfig option to be selected on architectures which do not
enable ISA (e.g. X86_64).
The ISA_BUS Kconfig option is currently only implemented for X86
architectures. Other architectures may have their own ISA_BUS Kconfig
options added as required.

2) Two fixes for insufficient ruleset loop validation, one due to

silly wrong generation mask logic from the walk path, from Liping
Zhang.
3) Fix double-free of anonymous sets on error, this fix simplifies the

also from Liping Zhang.
4) The introduction of helper function for transactions broke the skip
inactive rules logic from the nft_do_chain(), again from Liping

Swapping a cable from a "Mgmt Allowed=No" switch port to a
"Mgmt Allowed=Yes" switch port doesn't send a pkey change
notification. Therefore, the link doesn't become active as
the oib_utils layer uses an old pkey table cache.
Fix by ensuring the pkey change notification is sent when
the table is changed both explicitly by the FM and implicitly
by the driver via a cable swap.

This reverts commit b5e12ec38331 ("Staging: rtl8188eu: rtw_efuse: Use
sizeof type *pointer instead of sizeof type.").
This commit is wrong, the rtw_malloc2d helper function takes the size of
the array elements as its 3th argument, whereas sizeof(*eFuseWord)
gives the size of a pointer instead of the size of a u16.
Since sizeof(void *) > sizeof(u16) this has no adverse effects, but it
is still wrong.

This reverts commit 99aded71b52c ("Staging: drivers: rtl8188eu: use
sizeof(*ptr) instead of sizeof(struct)").
This commit is wrong, as adapt->HalData has a type of "void *", so
now we are allocating a much to small struct, which causes the driver
to overwrite random memory which leads to a non working driver and
various system crashes.

There is no limit on high "idx" can go. It should be less than
ARRAY_SIZE(data.states) which is 16.
The "data" variable wasn't declared in that scope so I shifted the code
around a bit to make it work. Also I made "idx" unsigned.
