This adds the infrastructure to register nat hooks with the nat core
instead of the netfilter core.
nat hooks are used to configure nat bindings. Such hooks are registered
from ip(6)table_nat or by the nftables core when a nat chain is added.
After next patch, nat hooks will be registered with nf_nat instead of
netfilter core. This allows to use many nat lookup functions at the
same time while doing the real packet rewrite (nat transformation) in
one place.
This change doesn't convert the intended users yet to ease review.

This will allow the nat core to reuse the nf_hook infrastructure
to maintain nat lookup functions.
The raw versions don't assume a particular hook location, the
functions get added/deleted from the hook blob that is passed to the
functions.

The ip(6)tables nat table is currently receiving skbs from the netfilter
core, after a followup patch skbs will be coming from the netfilter nat
core instead, so the table is no longer backed by normal hook_ops.

Stephen Rothwell says:
today's linux-next build (x86_64 allmodconfig) produced this warning:
./usr/include/linux/netfilter/nf_osf.h:25: found __[us]{8,16,32,64} type without #include <linux/types.h>
Fix that up and also move kernel-private struct out of uapi (it was not
exposed in any released kernel version).

The bpf syscall and selftests conflicts were trivial
overlapping changes.
The r8169 change involved moving the added mdelay from 'net' into a
different function.
A TLS close bug fix overlapped with the splitting of the TLS state
into separate TX and RX parts. I just expanded the tests in the bug
fix from "ctx->conf == X" into "ctx->tx_conf == X && ctx->rx_conf
== X".

When application fails to pass flags in netlink TLV when replacing
existing skbmod action, the kernel will leak refcnt:
$ tc actions get action skbmod index 1
total acts 0
action order 0: skbmod pipe set smac 00:11:22:33:44:55
index 1 ref 1 bind 0
For example, at this point a buggy application replaces the action with
index 1 with new smac 00:aa:22:33:44:55, it fails because of zero flags,
however refcnt gets bumped:
$ tc actions get actions skbmod index 1
total acts 0
action order 0: skbmod pipe set smac 00:11:22:33:44:55
index 1 ref 2 bind 0
$
Tha patch fixes this by calling tcf_idr_release() on existing actions.

Add support for the DP83811 phy.
The DP83811 supports both rgmii and sgmii interfaces.
There are 2 part numbers for this the DP83TC811R does not
reliably support the SGMII interface but the DP83TC811S will.
There is not a way to differentiate these parts from the
hardware or register set. So this is controlled via the DT
to indicate which phy mode is required. Or the part can be
strapped to a certain interface.

Calling the variable l3edev was relevant when neighbor lookup was the
last stage in the simulated pipeline. Now that mlxsw handles bridges and
vlan devices as well, calling it "L3" is a misnomer.
Thus in mlxsw_sp_span_dmac(), rename to "dev", because that function is
just a service routine where the distinction between tunnel and egress
device isn't necessary.
In mlxsw_sp_span_entry_tunnel_parms_common(), rename to "edev" to
emphasize that the routine traces packet egress.

The caller calls action's ->init() and passes pointer to "struct tc_action *a",
which later may be initialized to point at the existing action, otherwise
"struct tc_action *a" is still invalid, and therefore dereferencing it is an
error as happens in tcf_idr_release, where refcnt is decremented.
So in case of missing flags tcf_idr_release must be called only for

Prior to this commit, the rq_last_status was only set when hardware
responded with an error. This leads to rq_last_status being invalid
in the future when hardware eventually responds without error. This

Commit 0fa1c579349f ("of/fdt: use memblock_virt_alloc for early alloc")
inadvertently switched the DT unflattening allocations from memblock to
bootmem which doesn't work because the unflattening happens before
bootmem is initialized. Swapping the order of bootmem init and
unflattening could also fix this, but removing bootmem is desired. So
enable NO_BOOTMEM on SH like other architectures have done.

The internal VM "mmap()" interfaces are based on the mmap target doing
everything using page indexes rather than byte offsets, because
traditionally (ie 32-bit) we had the situation that the byte offset
didn't fit in a register. So while the mmap virtual address was limited
by the word size of the architecture, the backing store was not.
So we're basically passing "pgoff" around as a page index, in order to
be able to describe backing store locations that are much bigger than
the word size (think files larger than 4GB etc).
But while this all makes a ton of sense conceptually, we've been dogged
by various drivers that don't really understand this, and internally
work with byte offsets, and then try to work with the page index by
turning it into a byte offset with "pgoff << PAGE_SHIFT".
Which obviously can overflow.
Adding the size of the mapping to it to get the byte offset of the end
of the backing store just exacerbates the problem, and if you then use
this overflow-prone value to check various limits of your device driver
mmap capability, you're just setting yourself up for problems.
The correct thing for drivers to do is to do their limit math in page
indices, the way the interface is designed. Because the generic mmap
code _does_ test that the index doesn't overflow, since that's what the
mmap code really cares about.
HOWEVER.
Finding and fixing various random drivers is a sisyphean task, so let's
just see if we can just make the core mmap() code do the limiting for
us. Realistically, the only "big" backing stores we need to care about
are regular files and block devices, both of which are known to do this
properly, and which have nice well-defined limits for how much data they
can access.
So let's special-case just those two known cases, and then limit other
random mmap users to a backing store that still fits in "unsigned long".
Realistically, that's not much of a limit at all on 64-bit, and on
32-bit architectures the only worry might be the GPU drivers, which can
have big physical address spaces.
To make it possible for drivers like that to say that they are 64-bit
clean, this patch does repurpose the "FMODE_UNSIGNED_OFFSET" bit in the
file flags to allow drivers to mark their file descriptors as safe in
the full 64-bit mmap address space.
[ The timing for doing this is less than optimal, and this should really
go in a merge window. But realistically, this needs wide testing more
than it needs anything else, and being main-line is the only way to do
that.
So the earlier the better, even if it's outside the proper development
cycle - Linus ]

linux-4.16 got support for softirq based hrtimers.
TCP can switch its pacing hrtimer to this variant, since this
avoids going through a tasklet and some atomic operations.
pacing timer logic looks like other (jiffies based) tcp timers.
v2: use hrtimer_try_to_cancel() in tcp_clear_xmit_timers()
to correctly release reference on socket if needed.

====================
net: dsa: Plug in PHYLINK support
This patch series adds PHYLINK support to DSA which is necessary to support more
complex PHY and pluggable modules setups.
Patch series can be found here:
https://github.com/ffainelli/linux/commits/dsa-phylink-v2
This was tested on:
- dsa-loop
- bcm_sf2
- mv88e6xxx
- b53
With a variety of test cases:
- internal & external MDIO PHYs
- MoCA with link notification through interrupt/MMIO register
- built-in PHYs
- ifconfig up/down for several cycles works
- bind/unbind of the drivers
Changes in v2:
- fixed link configuration for mv88e6xxx (Andrew) after introducing polling
This is technically v2 of what was posted back in March 2018, changes from last
time:
- fixed probe/remove of drivers
- fixed missing gpiod_put() for link GPIOs
- fixed polling of link GPIOs (Russell I would need your SoB on the patch you
provided offline initially, added some modifications to it)
- tested across a wider set of platforms
And everything should still work as expected. Please be aware of the following:
- switch drivers (like bcm_sf2) which may have user-facing network ports using
fixed links would need to implement phylink_mac_ops to remain functional.
PHYLINK does not create a phy_device for fixed links, therefore our
call to adjust_link() from phylink_mac_link_{up,down} would not be calling
into the driver. This *should not* affect CPU/DSA ports which are configured
through adjust_link() but have no network devices
- support for SFP/SFF is now possible, but switch drivers will still need some
modifications to properly support those, including, but not limited to using
the correct binding information. This will be submitted on top of this series
Please do test on your respective platforms/switches and let me know if you
find any issues, hopefully everything still works like before.
