Kevin Darbyshire-Bryant d59dc14515 kernel: cake: backport upstream tweaks & fixes
From upstream:
b8392808eb3f sch_cake: add RFC 8622 LE PHB support to CAKE diffserv handling
3f608f0c4136 sch_cake: fix a few style nits
8c95eca0bb8c sch_cake: don't call diffserv parsing code when it is not needed
9208d2863ac6 sch_cake: don't try to reallocate or unshare skb unconditionally

From netdev not yet accepted:
sch_cake: fix IP protocol handling in the presence of VLAN tags

The VLAN tag handling is actually wider than just cake so upstream are
working out how to fix it generically.  We fix it here just for cake.

Kevin Darbyshire-Bryant b74386acc6 kmod-sched-cake: switch to in-tree cake for 4.19+
Use in tree version of cake for kernels 4.19+ and backport features from
later kernel versions to 4.19.

Unfortunately PROVIDES dependency handling produces bogus circular
dependency warnings so whilst this package and kmod-sched-cake-oot
should be able to PROVIDE kmod-sched-cake this doesn't work.

Instead, remove the PROVIDES option and modify package sqm-scripts to
depend on the correct module independently.

Jeff Kletsky b9d58f7e06 kernel: mtd: spinand: Backport chip definitions
generic: Add/rename patches for upstream consistency

ipq40xx: generic-level patch replaces same-source patches-4.19/
         082-v4.20-mtd-spinand-winbond-Add-support-for-W25N01GV.patch

The SPI-NAND framework from Linux uses common driver code that is then
"tuned" by a tiny struct of chip-specific data that describes
available commands, timing, and layout (data and OOB data). Several
manufacturers and chips have been added since 4.19, several of which
are used in devices already supported by OpenWrt (typically with no or
"legacy" access to their NAND memory). This commit catches up the
supported-chip definitions through Linux 5.2-rc6 and linux/next.

The driver is only compiled for platforms with CONFIG_MTD_SPI_NAND=y.
This presently includes ipq40xx and pistachio, with the addition of
ath79-nand in these commits (and not ath79-generic or ath79-tiny).

Upstream patches refreshed against 4.19.75

Hauke Mehrtens 16f84fd275 kernel: Fix arm64 include files
This patch fixes the build of gdb and strace on arm64 targets with
kernel 4.19.

Without this patch asm/ptrace.h is including asm/sigcontext.h and this
file defines some structures which are also defined in musl header file
arch/aarch64/bits/signal.h. These two definitions then conflict with
each other and make the build fail.

This was seen locally and also by the build bot. The struct sigcontext,
struct sve_context and some others were defined twice. It looks like
this problem was introduced between 4.14 and 4.19 and it was fixed in
5.0. I already requested to backport this patch to kernel 4.19.

Cong Wang 7735cce0c5 kernel: net_sched: fix a NULL pointer deref in ipt action
The net pointer in struct xt_tgdtor_param is not explicitly
initialized therefore is still NULL when dereferencing it.
So we have to find a way to pass the correct net pointer to
ipt_destroy_target().

The best way I find is just saving the net pointer inside the per
netns struct tcf_idrinfo, which could make this patch smaller.

Martin Schiller aac25bdba5 kernel: 4.19: Backport usb dwc2 lpm mode hw check
This patch backports verbatim the commit from Linux 5.2-rc7 that fixes
the warnings about invalid lpm related parameters on hardware which
don't that.

This is the case for e.g. lantiq xrx200 targets.

Supported only in Linux 4.17 an later.

Kevin Darbyshire-Bryant 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---|
      |                   |
      |                   |
      ---|             Conditional flag
         v             only restore if set
|-ip diffserv-|
| 6 bits      |
|-------------|

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.

|----0x00----conntrack mark----ffffff---|
| Bits 31-24 |                          |
| DSCP & flag|      some value here     |

|---------------------------------------|

Overall parameters:

zone - conntrack zone

control - action related control (reclassify | pipe | drop | continue |
ok | goto chain <CHAIN_INDEX>)
