1e028ac51e kernel: further cleanup of xfrm[4|6]_mode*
In my commit da5c45f4d8 ("kernel: remove handling of xfrm[4|6]_mode_*
modules") I missed a few default config options and description entries.
Those should be gone as well.

da5c45f4d8 kernel: remove handling of xfrm[4|6]_mode_* modules
For kernel versions before 5.2, the required IPsec modes have to be
enabled explicitly (they are built-in for newer kernels).

Commit 1556ed155a ("kernel: mode_beet mode_transport mode_tunnel xfram
modules") tried to handle this, but it does not really work.

Since we don't support these kernel versions anymore and the code is
also broken, let's remove it.

05775e38a5 kernel: extract kmod-sched-act-ipt from kmod-sched
There is only one module in kmod-sched that depends on iptables. Move it
to its own kmod package so we can drop the kmod-ipt-core dependency from
kmod-sched. This makes it possible to disable all kmod-ipt-* packages
without having to disable kmod-sched. Since we now default to firewall4
and nftables, we should avoid iptables dependencies where we can.

488b25f5ac kernel: netconsole: add network console logging support
Accessing the console on many devices is difficult.
netconsole eases debugging on devices that crash
after the network is up.

Reference to the netconsole documentation in upstream Linux:
<https://www.kernel.org/doc/html/latest/networking/netconsole.html>
|
|netconsole=[+][src-port]@[src-ip]/[<dev>],[tgt-port]@<tgt-ip>/[tgt-macaddr]
|
| where
|  +            if present, enable extended console support
|  src-port     source for UDP packets (defaults to 6665)
|  src-ip       source IP to use (interface address)
|  dev          network interface (eth0)
|  tgt-port     port for logging agent (6666)
|  tgt-ip       IP address for logging agent
|  tgt-macaddr  ethernet MAC address for logging agent (broadcast)

OpenWrt specific notes:

OpenWrt's device userspace scripts are attaching the network
interface (i.e. eth0) to a (virtual) bridge (br-lan) device.
This will cause netconsole to report:
|network logging stopped on interface eth0 as it is joining a master device
(and unfortunately the traffic/logs to stop at this point)

As a workaround, the netconsole module can be manually loaded
again after the bridge has been setup with:

 insmod netconsole netconsole=@/br-lan,@192.168.1.x/MA:C...

One way of catching errors before the handoff, try to
append the /etc/modules.conf file with the following extra line:
 options netconsole netconsole=@/eth0,@192.168.1.x/MA:C...

and install the kmod-netconsole (=y) into the base image.

b69dfb0a99 kernel/modules: prevent bonding driver to create default bond0 interface
When loading the bonding driver, bonding interface are automatically
created on bonding module load.

> ip a s bond0

> group default qlen 1000
>    link/ether a6:f2:20:64:c1:b9 brd ff:ff:ff:ff:ff:ff

This is not necessary in openwrt as we do not use this created interface.
The netifd creates a bonding interface based on its network configuration
name and configures this over the netifd bonding proto handler.

In order to keep the overview of the interfaces clear, bonding
interfaces should not be created automatically when loading this module,
because they are not used anyway.

863ce4f15f kernel/modules: relocate teql hotplug from iproute2 to kmod-sched
The link equalizer sch_teql.ko of package kmod-sched relies on a hotplug
script historically included in iproute2's tc package. In previous
discussion [1], consensus was the hotplug script is best located together
with the module in kmod-sched, but this change was deferred at the time.

Relocate the hotplug script now. This change also simplifies adding a tc
variant for minimal size with reduced functionality.

"Whoop whoop, sound of da police"

Add an ingress capable traffic policer module configurable with tc.

From the man page:

The police action allows to limit bandwidth of traffic matched by the
filter it is attached to. Basically there are two different algorithms
available to measure the packet rate: The first one uses an internal
dual token bucket and is configured using the rate, burst, mtu,
peakrate, overhead and linklayer parameters. The second one uses an
in-kernel sampling mechanism. It can be fine-tuned using the estimator
filter parameter.

2e6b6f9fca kernel: add @IPV6 dependency to ipv6 modules
IPv6 modules should all depend on @IPV6, to avoid circular dependencies
problems, especially if they select a module that depends on IPV6 as
well.  In theory, if a package A depends on IPV6, any package doing
'select A' (DEPENDS+= A) should also depend on IPV6; otherwise selecting
A will fail.  Sometimes the build system is forgiving this, but
eventually, and unexpectedly, it may blow up on some other commit.

Alternatively one can conditionally add IPv6 dependencies only if
CONFIG_IPV6 is selected: (DEPENDS+= +IPV6:package6).

b8a72dfd28 kernel: backport act_ctinfo
ctinfo is a new tc filter action module.  It is designed to restore
information contained in firewall conntrack marks to other packet fields
and is typically used on packet ingress paths.  At present it has two
independent sub-functions or operating modes, DSCP restoration mode &
skb mark restoration mode.

The DSCP restore mode:

This mode copies DSCP values that have been placed in the firewall
conntrack mark back into the IPv4/v6 diffserv fields of relevant
packets.

The DSCP restoration is intended for use and has been found useful for
restoring ingress classifications based on egress classifications across
links that bleach or otherwise change DSCP, typically home ISP Internet
links.  Restoring DSCP on ingress on the WAN link allows qdiscs such as
but by no means limited to CAKE to shape inbound packets according to
policies that are easier to set & mark on egress.

Ingress classification is traditionally a challenging task since
iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
lookups, hence are unable to see internal IPv4 addresses as used on the
typical home masquerading gateway.  Thus marking the connection in some
manner on egress for later restoration of classification on ingress is
easier to implement.

Parameters related to DSCP restore mode:

dscpmask - a 32 bit mask of 6 contiguous bits and indicate bits of the
conntrack mark field contain the DSCP value to be restored.

statemask - a 32 bit mask of (usually) 1 bit length, outside the area
specified by dscpmask.  This represents a conditional operation flag
whereby the DSCP is only restored if the flag is set.  This is useful to
implement a 'one shot' iptables based classification where the
'complicated' iptables rules are only run once to classify the
connection on initial (egress) packet and subsequent packets are all
marked/restored with the same DSCP.  A mask of zero disables the
conditional behaviour ie. the conntrack mark DSCP bits are always
restored to the ip diffserv field (assuming the conntrack entry is found
& the skb is an ipv4/ipv6 type)

e.g. dscpmask 0xfc000000 statemask 0x01000000

|----0xFC----conntrack mark----000000---|
| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0|
| DSCP       | unused | flag  |unused   |
|-----------------------0x01---000000---|
      |                   |

The skb mark restore mode (cpmark):

This mode copies the firewall conntrack mark to the skb's mark field.
It is completely the functional equivalent of the existing act_connmark
action with the additional feature of being able to apply a mask to the
restored value.

Parameters related to skb mark restore mode:

mask - a 32 bit mask applied to the firewall conntrack mark to mask out
bits unwanted for restoration.  This can be useful where the conntrack
mark is being used for different purposes by different applications.  If
not specified and by default the whole mark field is copied (i.e.
default mask of 0xffffffff)

e.g. mask 0x00ffffff to mask out the top 8 bits being used by the
aforementioned DSCP restore mode.

| Bits 31-24 |                          |
