Subject: [PATCH] netfilter: connmark: introduce set-dscpmark
set-dscpmark is a method of storing the DSCP of an ip packet into
conntrack mark. In combination with a suitable tc filter action
(act_ctinfo) DSCP values are able to be stored in the mark on egress and
restored on ingress across links that otherwise alter or bleach DSCP.
This is useful for qdiscs such as CAKE which are able to shape according
to policies based on DSCP.
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.
x_tables CONNMARK set-dscpmark target solves the problem of storing the
DSCP to the conntrack mark in a way suitable for the new act_ctinfo tc
action to restore.
The set-dscpmark option accepts 2 parameters, a 32bit 'dscpmask' and a
32bit 'statemask'. The dscp mask must be 6 contiguous bits and
represents the area where the DSCP will be stored in the connmark. The
state mask is a minimum 1 bit length mask that must not overlap with the
dscpmask. It represents a flag which is set when the DSCP has been
stored in the conntrack mark. 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 state
mask of zero disables the setting of a status bit/s.
example syntax with a suitably modified iptables user space application:
iptables -A QOS_MARK_eth0 -t mangle -j CONNMARK --set-dscpmark 0xfc000000/0x01000000
Would store the DSCP in the top 6 bits of the 32bit mark field, and use
the LSB of the top byte as the 'DSCP has been stored' marker.

From dd109ded2b526636fff438d33433ab64ffd21583 Mon Sep 17 00:00:00 2001
From: Georgi Valkov <gvalkov@abv.bg>
Date: Fri, 16 Apr 2021 20:44:36 +0300
Subject: [PATCH] ipheth: fix EOVERFLOW in ipheth_rcvbulk_callback
When rx_buf is allocated we need to account for IPHETH_IP_ALIGN,
which reduces the usable size by 2 bytes. Otherwise we have 1512
bytes usable instead of 1514, and if we receive more than 1512
bytes, ipheth_rcvbulk_callback is called with status -EOVERFLOW,
after which the driver malfunctiones and all communication stops.
Fixes: ipheth 2-1:4.2: ipheth_rcvbulk_callback: urb status: -75

Subject: [PATCH] compiler.h: only include asm/rwonce.h for kernel code
This header file is not in uapi, which makes any user space code that includes
linux/compiler.h to fail with the error 'asm/rwonce.h: No such file or directory'
Fixes: e506ea451254 ("compiler.h: Split {READ,WRITE}_ONCE definitions out into rwonce.h")

From 3d00da1de3ea36ba44f4a7ba76c8c8b16f98204b Mon Sep 17 00:00:00 2001

Subject: [PATCH] platform/x86: pcengines-apuv2: detect apuv4 board
GPIO stuff on APUv4 seems to be the same as on APUv2, so we just
need to match on DMI data.
