The referenced commit below allowed more than one hwmon device to be
created per SFP, which is definitely not what we want. Avoid this by
only creating the hwmon device just as we transition to WAITDEV state.

If the user has specified their own RSS hash key, don't
lose it across queue resets such as DOWN/UP, MTU change,
and number of channels change. This is fixed by moving
the key initialization to a little earlier in the lif

The act_ct TC module shares a common conntrack and NAT infrastructure
exposed via netfilter. It's possible that a packet needs both SNAT and
DNAT manipulation, due to e.g. tuple collision. Netfilter can support
this because it runs through the NAT table twice - once on ingress and
again after egress. The act_ct action doesn't have such capability.
Like netfilter hook infrastructure, we should run through NAT twice to
keep the symmetry.

====================
net: convert ipv6_stub to ip6_dst_lookup_flow
Xiumei Mu reported a bug in a VXLAN over IPsec setup:
IPv6 | ESP | VXLAN
Using this setup, packets go out unencrypted, because VXLAN over IPv6
gets its route from ipv6_stub->ipv6_dst_lookup (in vxlan6_get_route),
which doesn't perform an XFRM lookup.
This patchset first makes ip6_dst_lookup_flow suitable for some
existing users of ipv6_stub->ipv6_dst_lookup by adding a 'net'
argument, then converts all those users.
====================

ipv6_stub uses the ip6_dst_lookup function to allow other modules to
perform IPv6 lookups. However, this function skips the XFRM layer
entirely.
All users of ipv6_stub->ip6_dst_lookup use ip_route_output_flow (via the
ip_route_output_key and ip_route_output helpers) for their IPv4 lookups,
which calls xfrm_lookup_route(). This patch fixes this inconsistent
behavior by switching the stub to ip6_dst_lookup_flow, which also calls
xfrm_lookup_route().
This requires some changes in all the callers, as these two functions
take different arguments and have different return types.

This will be used in the conversion of ipv6_stub to ip6_dst_lookup_flow,
as some modules currently pass a net argument without a socket to
ip6_dst_lookup. This is equivalent to commit 343d60aada5a ("ipv6: change
ipv6_stub_impl.ipv6_dst_lookup to take net argument").

The recent commit 5c72299fba9d ("net: sched: cls_flower: Classify
packets using port ranges") had added filtering based on port ranges
to tc flower. However the commit missed necessary changes in hw-offload
code, so the feature gave rise to generating incorrect offloaded flow
keys in NIC.
One more detailed example is below:
$ tc qdisc add dev eth0 ingress
$ tc filter add dev eth0 ingress protocol ip flower ip_proto tcp \
dst_port 100-200 action drop
With the setup above, an exact match filter with dst_port == 0 will be
installed in NIC by hw-offload. IOW, the NIC will have a rule which is
equivalent to the following one.
$ tc qdisc add dev eth0 ingress
$ tc filter add dev eth0 ingress protocol ip flower ip_proto tcp \
dst_port 0 action drop
The behavior was caused by the flow dissector which extracts packet
data into the flow key in the tc flower. More specifically, regardless
of exact match or specified port ranges, fl_init_dissector() set the
FLOW_DISSECTOR_KEY_PORTS flag in struct flow_dissector to extract port
numbers from skb in skb_flow_dissect() called by fl_classify(). Note
that device drivers received the same struct flow_dissector object as
used in skb_flow_dissect(). Thus, offloaded drivers could not identify
which of these is used because the FLOW_DISSECTOR_KEY_PORTS flag was
set to struct flow_dissector in either case.
This patch adds the new FLOW_DISSECTOR_KEY_PORTS_RANGE flag and the new
tp_range field in struct fl_flow_key to recognize which filters are applied
to offloaded drivers. At this point, when filters based on port ranges
passed to drivers, drivers return the EOPNOTSUPP error because they do
not support the feature (the newly created FLOW_DISSECTOR_KEY_PORTS_RANGE
flag).

It appears linux-4.14 stable needs a backport of commit
88f8598d0a30 ("tcp: exit if nothing to retransmit on RTO timeout")
Since tcp_rtx_queue_empty() is not in pre 4.15 kernels,
let's refactor tcp_retransmit_timer() to only use tcp_rtx_queue_head()
I will provide to stable teams the squashed patches.

Currently a switch driver deinit frees the regmaps, but the PTP clock is
still out there, available to user space via /dev/ptpN. Any PTP
operation is a ticking time bomb, since it will attempt to use the freed
regmaps and thus trigger kernel panics:

We have an interesting memory leak in the bridge when it is being
unregistered and is a slave to a master device which would change the
mac of its slaves on unregister (e.g. bond, team). This is a very
unusual setup but we do end up leaking 1 fdb entry because
dev_set_mac_address() would cause the bridge to insert the new mac address
into its table after all fdbs are flushed, i.e. after dellink() on the
bridge has finished and we call NETDEV_UNREGISTER the bond/team would
release it and will call dev_set_mac_address() to restore its original
address and that in turn will add an fdb in the bridge.
One fix is to check for the bridge dev's reg_state in its
ndo_set_mac_address callback and return an error if the bridge is not in
NETREG_REGISTERED.
Easy steps to reproduce:
1. add bond in mode != A/B
2. add any slave to the bond
3. add bridge dev as a slave to the bond
4. destroy the bridge device

The skb_mpls_pop was not updating ethertype of an ethernet packet if the
packet was originally received from a non ARPHRD_ETHER device.
In the below OVS data path flow, since the device corresponding to port 7
is an l3 device (ARPHRD_NONE) the skb_mpls_pop function does not update
the ethertype of the packet even though the previous push_eth action had
added an ethernet header to the packet.
recirc_id(0),in_port(7),eth_type(0x8847),
mpls(label=12/0xfffff,tc=0/0,ttl=0/0x0,bos=1/1),

pull-request: bpf 2019-12-02
The following pull-request contains BPF updates for your *net* tree.
We've added 10 non-merge commits during the last 6 day(s) which contain
a total of 10 files changed, 60 insertions(+), 51 deletions(-).
The main changes are:
1) Fix vmlinux BTF generation for binutils pre v2.25, from Stanislav Fomichev.
2) Fix libbpf global variable relocation to take symbol's st_value offset
into account, from Andrii Nakryiko.
3) Fix libbpf build on powerpc where check_abi target fails due to different
readelf output format, from Aurelien Jarno.
4) Don't set BPF insns RO for the case when they are JITed in order to avoid
fragmenting the direct map, from Daniel Borkmann.
5) Fix static checker warning in btf_distill_func_proto() as well as a build
error due to empty enum when BPF is compiled out, from Alexei Starovoitov.
6) Fix up generation of bpf_helper_defs.h for perf, from Arnaldo Carvalho de Melo.

On powerpc with recent versions of binutils, readelf outputs an extra
field when dumping the symbols of an object file. For example:
35: 0000000000000838 96 FUNC LOCAL DEFAULT [<localentry>: 8] 1 btf_is_struct
The extra "[<localentry>: 8]" prevents the GLOBAL_SYM_COUNT variable to
be computed correctly and causes the check_abi target to fail.
Fix that by looking for the symbol name in the last field instead of the
8th one. This way it should also cope with future extra fields.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.5 kernel cycle
Core changes:
- Expose pull up/down flags for the GPIO character device to
userspace.
After clear input from the RaspberryPi and Beagle communities, it
has been established that prototyping, industrial automation and
make communities strongly need this feature, and as we want people
to use the character device, we have implemented the simple pull
up/down interface for GPIO lines.
This means we can specify that a (chip-specific) pull up/down
resistor can be enabled, but does not offer fine-grained control
such as cases where the resistance of the same pull resistor can be
controlled (yet).
- Introduce devm_fwnode_gpiod_get_index() and start to phase out the
old symbol devm_fwnode_get_index_gpiod_from_child().
- A bit of documentation clean-up work.
- Introduce a define for GPIO line directions and deploy it in all
GPIO drivers in the drivers/gpio directory.
- Add a special callback to populate pin ranges when cooperating with
the pin control subsystem and registering ranges as part of adding
a gpiolib driver and a gpio_irq_chip driver at the same time. This
is also deployed in the Intel Merrifield driver.
New drivers:
- RDA Micro GPIO controller.
- XGS-iproc GPIO driver.
Driver improvements:
- Wake event and debounce support on the Tegra 186 driver.
- Finalize the Aspeed SGPIO driver.
- MPC8xxx uses a normal IRQ handler rather than a chained handler"

Pull clk updates from Stephen Boyd:
"This merge window we have one small clk provider API in the core
framework and then a bunch of driver updates and a handful of new
drivers. In terms of diffstat the Qualcomm and Amlogic drivers are
high up there because of all the clk data introcued by new drivers.
The Nvidia Tegra driver had a lot of work done this cycle too to
support suspend/resume and memory controllers. And the OMAP clk driver
got proper clk and reset handling in place.
Rounding out the patches are various updates to remove unused data,
mark things static, correct incorrect data in drivers, etc. All the
little things that improve drivers and maintain code health. I will
point out that there's a patch in here for the GPIO clk driver, that
almost nobody uses, which changes behavior and causes clk_set_rate()
to try to change the GPIO gate clk's parent. Other than that things
are fairly well SoC specific here.
Core:
- Add a clk provider API to get current parent index
- Plug a memory leak in clk_unregister() path
New Drivers:
- CGU in Ingenix X1000
- Bitmain BM1880 clks
- Qualcomm MSM8998 GPU clk controllers
- Qualcomm SC7180 GCC and RPMH clk controllers
- Qualcomm QCS404 Q6SSTOP clk controllers
- Add support for the Renesas R-Car M3-W+ (r8a77961) SoC
- Add support for the Renesas RZ/G2N (r8a774b1) SoC
- Add Tegra20/30 External Memory Clock (EMC) support
Updates:
- Make gpio gate clks propagate rate setting up to parent
- Prepare Armada 3700 for suspend to RAM by moving PCIe
suspend/resume priority
- Drop unused variables, enums, etc. in various clk drivers
- Convert various drivers to use devm_platform_ioremap_resource()
- Use struct_size() some more in various clk drivers
- Improve Rockchip px30 clk tree
- Add suspend/resume support to Tegra210 clk driver
- Reimplement SOR clks on earlier Tegra SoCs, helping HDMI and DP
- Allwinner DT exports and H6 clk tree fixes
- Proper clk and reset handling for OMAP SoCs
- Revamped TI divider clk to clamp max divider
- Make 1443X/1416X PLL clock structure common for reusing among i.MX8
SoCs
- Drop IMX7ULP_CLK_MIPI_PLL clock, it shouldn't be used
- Add VIDEO2_PLL clock for imx8mq
- Add missing gate clock for pll1/2 fixed dividers on i.MX8 SoCs
- Add sm1 support in the Amlogic audio clock controller
- Switch some clocks on R-Car Gen2/3 to .determine_rate()
- Remove Renesas R-Car Gen2 legacy DT clock support
- Improve arithmetic divisions on Renesas R-Car Gen2 and Gen3
- Improve Renesas R-Car Gen3 SD clock handling
- Add rate table for Samsung exynos542x GPU and VPLL clks
- Fix potential CPU performance degradation after system
suspend/resume cycle on exynos542x SoCs"

Pull y2038 cleanups from Arnd Bergmann:
"y2038 syscall implementation cleanups
This is a series of cleanups for the y2038 work, mostly intended for
namespace cleaning: the kernel defines the traditional time_t, timeval
and timespec types that often lead to y2038-unsafe code. Even though
the unsafe usage is mostly gone from the kernel, having the types and
associated functions around means that we can still grow new users,
and that we may be missing conversions to safe types that actually
matter.
There are still a number of driver specific patches needed to get the
last users of these types removed, those have been submitted to the
respective maintainers"

Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
"As part of the cleanup of some remaining y2038 issues, I came to
fs/compat_ioctl.c, which still has a couple of commands that need
support for time64_t.
In completely unrelated work, I spent time on cleaning up parts of
this file in the past, moving things out into drivers instead.
After Al Viro reviewed an earlier version of this series and did a lot
more of that cleanup, I decided to try to completely eliminate the
rest of it and move it all into drivers.
This series incorporates some of Al's work and many patches of my own,
but in the end stops short of actually removing the last part, which
is the scsi ioctl handlers. I have patches for those as well, but they
need more testing or possibly a rewrite"
