vxlan metadata device vnifiltering support
This series adds vnifiltering support to vxlan collect metadata device.
Motivation:
You can only use a single vxlan collect metadata device for a given
vxlan udp port in the system today. The vxlan collect metadata device
terminates all received vxlan packets. As shown in the below diagram,
there are use-cases where you need to support multiple such vxlan devices in
independent bridge domains. Each vxlan device must terminate the vni's
it is configured for.
Example usecase: In a service provider network a service provider
typically supports multiple bridge domains with overlapping vlans.
One bridge domain per customer. Vlans in each bridge domain are
mapped to globally unique vxlan ranges assigned to each customer.
This series adds vnifiltering support to collect metadata devices to
terminate only configured vnis. This is similar to vlan filtering in
bridge driver. The vni filtering capability is provided by a new flag on
collect metadata device.
In the below pic:
- customer1 is mapped to br1 bridge domain
- customer2 is mapped to br2 bridge domain
- customer1 vlan 10-11 is mapped to vni 1001-1002
- customer2 vlan 10-11 is mapped to vni 2001-2002
- br1 and br2 are vlan filtering bridges
- vxlan1 and vxlan2 are collect metadata devices with
vnifiltering enabled

With this implementation, vxlan dst metadata device can
be associated with range of vnis.
struct vxlan_vni_node is introduced to represent
a configured vni. We start with vni and its
associated remote_ip in this structure. This
structure can be extended to bring in other
per vni attributes if there are usecases for it.
A vni inherits an attribute from the base vxlan device
if there is no per vni attributes defined.
struct vxlan_dev gets a new rhashtable for
vnis called vxlan_vni_group. vxlan_vnifilter.c
implements the necessary netlink api, notifications
and helper functions to process and manage lifecycle
of vxlan_vni_node.
This patch also adds new helper functions in vxlan_multicast.c
to handle per vni remote_ip multicast groups which are part
of vxlan_vni_group.

Similarly when "efivar_ssdt=somestring" is used, it is added to the
Unknown parameter message and to init's environment strings, polluting
them (see examples above).
Change the return value of the __setup functions to 1 to indicate
that the __setup options have been handled.

In commit d687e056a1 ("soc: mediatek: mmsys: Add mt8192 mmsys routing table"),
the mmsys routing table for mt8192 was introduced but the input selector
for DITHER->DSI0 has no value assigned to it.
This means that we are clearing bit 0 instead of setting it, blocking
communication between these two blocks; due to that, any display that
is connected to DSI0 will not work, as no data will go through.
The effect of that issue is that, during bootup, the DRM will block for
some time, while atomically waiting for a vblank that never happens;
later, the situation doesn't get better, leaving the display in a
non-functional state.
To fix this issue, fix the route entry in the table by assigning the
dither input selector to MT8192_DISP_DSI0_SEL_IN.

Because there is no way to detect if the touchscreen has pen support,
the driver is allocating and registering the input_pen input_dev on
receiving the first pen event.
But this means that the input_dev gets allocated after the request_irq()
call which means that the devm framework will free it before disabling
the irq, leaving a window where the irq handler may run and reference the
free-ed input_dev.
To fix this move the allocation of the input_pen input_dev to before
the request_irq() call, while still only registering it on the first pen
event so that the driver does not advertise pen capability on touchscreens
without it (most goodix touchscreens do not have pen support).

The input core's error handling for input_alloc_absinfo() failures
is based on ignoring the error until input_register_device() runs
and then checks for the failure like this:
if (test_bit(EV_ABS, dev->evbit) && !dev->absinfo) {
dev_err(&dev->dev, ...);
return -EINVAL;
}
This relies on EV_ABS actually getting set in dev->evbit even
if input_alloc_absinfo() fails, change input_set_abs_params() and
input_set_capability() to actually adhere to this.

ACPI/x86 devices with a Cherry Trail SoC should have a GpioInt + a regular

Some CHT devices have a bug, where the also is bogus interrupt resource
(likely copied from a previous Bay Trail based generation of the device).
The i2c-core-acpi code will assign the bogus, non-working, interrupt
resource to client->irq. Add a workaround to fix this up.

2) I did some low level firmware command interface return status changes to
provide the caller with full visibility on the error/status returned by
the Firmware.
3) Use the new command interface in RDMA DEVX usecases to avoid flooding
dmesg with some "expected" user error prone use cases.
4) Moshe also uses the new command interface to grab the specific error
code from MFRL register command to provide the exact error reason for
why SW reset couldn't perform internally in FW.
5) From Mark Bloch: Lag, drop packets in hardware when possible
In active-backup mode the inactive interface's packets are dropped by the
bond device. In switchdev where TC rules are offloaded to the FDB
this can lead to packets being hit in the FDB where without offload
they would have been dropped before reaching TC rules in the kernel.
Create a drop rule to make sure packets on inactive ports are dropped
before reaching the FDB.
Listen on NETDEV_CHANGEUPPER / NETDEV_CHANGEINFODATA events and record
the inactive state and offload accordingly.

This driver, like several others, uses a chained IRQ for each GPIO bank,
and forwards .irq_set_wake to the GPIO bank's upstream IRQ. As a result,
a call to irq_set_irq_wake() needs to lock both the upstream and
downstream irq_desc's. Lockdep considers this to be a possible deadlock
when the irq_desc's share lockdep classes, which they do by default:

However, this can never deadlock because the upstream and downstream
IRQs are never the same (nor do they even involve the same irqchip).
Silence this erroneous lockdep splat by applying what appears to be the
usual fix of moving the GPIO IRQs to separate lockdep classes.

The commit that sets the direction directly without calling
pinctrl_gpio_direction(), forgot to add chip->base to the offset when
calling sunxi_pmx_gpio_set_direction().
This caused failures for various Allwinner boards which have two
GPIO blocks.

WSA SoundWire Controller does not support Clock stop and performs a soft reset
on suspend resume path. Its recommended that WSA881x codecs connected to this
are also reset using a hard reset during suspend resume.
So this codec driver performs a hard reset during suspend resume cycle.

Netfilter assumes its called with rcu_read_lock held, but in egress
hook case it may be called with BH readlock.
This triggers lockdep splat.
In order to avoid to change all rcu_dereference() to
rcu_dereference_check(..., rcu_read_lock_bh_held()), wrap nf_hook_slow
with read lock/unlock pair.
