sch_cake: Permit use of connmarks as tin classifiers
Add flag 'FWMARK' to enable use of firewall connmarks as tin selector.
The connmark (skbuff->mark) needs to be in the range 1->tin_cnt ie.
for diffserv3 the mark needs to be 1->3.
Background
Typically CAKE uses DSCP as the basis for tin selection. DSCP values
are relatively easily changed as part of the egress path, usually with
iptables & the mangle table, ingress is more challenging. CAKE is often
used on the WAN interface of a residential gateway where passthrough of
DSCP from the ISP is either missing or set to unhelpful values thus use
of ingress DSCP values for tin selection isn't helpful in that
environment.
An approach to solving the ingress tin selection problem is to use
CAKE's understanding of tc filters. Naive tc filters could match on
source/destination port numbers and force tin selection that way, but
multiple filters don't scale particularly well as each filter must be
traversed whether it matches or not. e.g. a simple example to map 3
firewall marks to tins:
MAJOR=$( tc qdisc show dev $DEV | head -1 | awk '{print $3}' )
tc filter add dev $DEV parent $MAJOR protocol all handle 0x01 fw action skbedit priority ${MAJOR}1
tc filter add dev $DEV parent $MAJOR protocol all handle 0x02 fw action skbedit priority ${MAJOR}2
tc filter add dev $DEV parent $MAJOR protocol all handle 0x03 fw action skbedit priority ${MAJOR}3
Another option is to use eBPF cls_act with tc filters e.g.
MAJOR=$( tc qdisc show dev $DEV | head -1 | awk '{print $3}' )
tc filter add dev $DEV parent $MAJOR bpf da obj my-bpf-fwmark-to-class.o
This has the disadvantages of a) needing someone to write & maintain
the bpf program, b) a bpf toolchain to compile it and c) needing to
hardcode the major number in the bpf program so it matches the cake
instance (or forcing the cake instance to a particular major number)
since the major number cannot be passed to the bpf program via tc
command line.
As already hinted at by the previous examples, it would be helpful
to associate tins with something that survives the Internet path and
ideally allows tin selection on both egress and ingress. Netfilter's
conntrack permits setting an identifying mark on a connection which
can also be restored to an ingress packet with tc action connmark e.g.
tc filter add dev eth0 parent ffff: protocol all prio 10 u32 \
match u32 0 0 flowid 1:1 action connmark action mirred egress redirect dev ifb1
Since tc's connmark action has restored any connmark into skb->mark,
any of the previous solutions are based upon it and in one form or
another copy that mark to the skb->priority field where again CAKE
picks this up.
This change cuts out at least one of the (less intuitive &
non-scalable) middlemen and permit direct access to skb->mark.

sch_cake: Make the dual modes fairer
CAKE host fairness does not work well with TCP flows in dual-srchost and
dual-dsthost setup. The reason is that ACKs generated by TCP flows are
classified as sparse flows, and affect flow isolation from other hosts. Fix
this by calculating host_load based only on the bulk flows a host
generates. In a hash collision the host_bulk_flow_count values must be
decremented on the old hosts and incremented on the new ones *if* the queue
is in the bulk set.

suspending phy and performing necessary cleanup of interrupts and BDs.
Upon resume, all these are reinitialized again.
Reset of macb device is done only when GEM is not a wake device.
Even when gem is a wake device, tx queues can be stopped and ptp device

====================
net: mvpp2: fixes and improvements
This series aims to improve the Marvell PPv2 driver and to fix various
issues we encountered while testing the ports in many different
configurations. The series is based on top of Russell PPv2 phylink
rework and improvement.
I'm not sending a v2 of the previous fixes series as half the patches
are not the same and lots of development happened in between.
While this series contains fixes, it's sent to net-next as it is based
on top of Russell patches that were merged into net-next. I'm also
aiming at net-next as the series reworks critical paths of the PPv2
driver, such as the reset handling of various blocks, to let more weeks
for users to tests and for possible fixes to be sent before it lands
into a stable kernel version.
The series is divided into three parts:
- Patches 1 to 3 are cosmetic changes, sent alongside the series, as I
saw these small issues while working on this.
- Patches 5 to 8 are fixing (or improving) individual issues that we
found while testing PPv2.1 and PPv2.2 ports while using various
interfaces.
Notable fixes are we support back RGMII interfaces (on both PPv2.1 and
PPv2.2), as their support was broken by previous patches. We also
reworked the RXQ computation as the RXQ assignment was not checking
the maximum number of RXQ available, and was broken for PPv2.1.
- As discussed in a previous fixes series, patches 9 to 15 rework the
way blocks are set in reset in the PPv2 engine (plus related changes).
There are four blocks we want to control the reset status: two MAC
(GMAC and XLG MAC) and two PCS (MPCS and XPCS). The XLG MAC is used
for 10G connexions and uses the MPCS or the XPCS depending on the mode
used (10GKR / XAUI / RXAUI) and the GMAC is used for the other modes.
The idea is to set all blocks in reset by default, and when not used,
and to de-assert the reset only when a block is used. There are four
cases to take in account:
1. Boot time: all four blocks should be put in reset, as we do not
know their initial state (configured by the firmware/bootloader).
2. Link up: only the blocks used by a given mode should be put out of
reset (eg. 10GKR uses the XLG MAC and the MPCS).
3. Mode reconfiguration: some ports may support mode reconfiguration,
and switching between the GMAC and the XLG MAC (or between the two
PCS). All blocks should be put in reset, and only the one used
should be put out of reset.
4. Link down: all four blocks are put in reset.

net: dsa: mv88e6xxx: prevent interrupt storm caused by mv88e6390x_port_set_cmode
When debugging another issue I faced an interrupt storm in this
driver (
88E6390, port 9 in SGMII mode), consisting of alternating
link-up / link-down interrupts. Analysis showed that the driver
wanted to set a cmode that was set already. But so far
mv88e6390x_port_set_cmode() doesn't check this and powers down
SERDES, what causes the link to break, and eventually results in
the described interrupt storm.
Fix this by checking whether the cmode actually changes. We want
that the very first call to mv88e6390x_port_set_cmode() always
configures the registers, therefore initialize port.cmode with
a value that is different from any supported cmode value.
We have to take care that we only init the ports cmode once
chip->info->num_ports is set.
v2:
- add small helper and init the number of actual ports only

This is a real stack undercorruption found by kasan build.
The issue did no harm normally because it only overflowed
2 bytes after `bitary` array which on most architectures
were mapped into `err` local.

The overflow is detected by smatch:

aq_pci_func_free_irqs() error: buffer overflow 'self->aq_vec' 8 <= 31
In reality msix_entry_mask always restricts number of iterations.
Adding extra condition to make logic clear and smatch happy.

There was actually no corruption because the array is

ipv4: Add ICMPv6 support when parse route ipproto
For ip rules, we need to use 'ipproto ipv6-icmp' to match ICMPv6 headers.
But for ip -6 route, currently we only support tcp, udp and icmp.
Add ICMPv6 support so we can match ipv6-icmp rules for route lookup.
v2: As David Ahern and Sabrina Dubroca suggested, Add an argument to
rtm_getroute_parse_ip_proto() to handle ICMP/ICMPv6 with different family.

MIPS: eBPF: Fix icache flush end address
The MIPS eBPF JIT calls flush_icache_range() in order to ensure the
icache observes the code that we just wrote. Unfortunately it gets the
end address calculation wrong due to some bad pointer arithmetic.
The struct jit_ctx target field is of type pointer to u32, and as such
adding one to it will increment the address being pointed to by 4 bytes.
Therefore in order to find the address of the end of the code we simply
need to add the number of 4 byte instructions emitted, but we mistakenly
add the number of instructions multiplied by 4. This results in the call
to flush_icache_range() operating on a memory region 4x larger than
intended, which is always wasteful and can cause crashes if we overrun
into an unmapped page.
Fix this by correcting the pointer arithmetic to remove the bogus
multiplication, and use braces to remove the need for a set of brackets
whilst also making it obvious that the target field is a pointer.

net/mlx5e: Update check for merged eswitch device
The current check only validates if both netdevs use the same ops
which means both are vf reps or both uplink reps.
Unlike the case where the two uplinks are bonded (VF LAG), under
multipath scheme the switchdev parent id is not unified between the
uplink reps (and all the associated vf reps). However, we still want
to duplicate in the driver encap flows, adjust the merged eswitch
check for that matter.
