tcp: Add listening address to SYN flood message
The SYN flood message prints the listening port number, but with many
processes bound to the same port on different IPs, it's impossible to
tell which socket is the problem.
Add the listen IP address to the SYN flood message.
For IPv6 use "[IP]:port" as per RFC-5952 and to provide ease of
copy-paste to "ss" filters. For IPv4 use "IP:port" to match.
Each protcol's "any" address and a host address now look like:
Possible SYN flooding on port 0.0.0.0:9001.
Possible SYN flooding on port 127.0.0.1:9001.
Possible SYN flooding on port [::]:9001.
Possible SYN flooding on port [fc00::1]:9001.

Steen Hegelund says:
====================
net: Add support for sorted VCAP rules in Sparx5
This provides support for adding Sparx5 VCAP rules in sorted order, VCAP
rule counters and TC filter matching on ARP frames.
It builds on top of the initial IS2 VCAP support found in these series:
https://lore.kernel.org/all/
20221020130904.1215072-1-steen.hegelund@microchip.com/
https://lore.kernel.org/all/
20221109114116.3612477-1-steen.hegelund@microchip.com/
Functionality
=============
When a new VCAP rule is added the driver will now ensure that the rule is
inserted in sorted order, and when a rule is removed, the remaining rules
will be moved to keep the sorted order and remove any gaps in the VCAP
address space.
A VCAP rule is ordered using these 3 values:
- Rule size: the count of VCAP addresses used by the rule. The largest
rule have highest priority
- Rule User: The rules are ordered by the user enumeration
- Priority: The priority provided in the flower filter. The lowest value
has the highest priority.
A VCAP instance may contain the counter as part of the VCAP cache area, and
this counter may be one or more bits in width. This type of counter
automatically increments its value when the rule is hit.
Other VCAP instances have a dedicated counter area outside of the VCAP and
in this case the rule must contain the counter id to be able to locate the
counter value and cause the counter to be incremented. In this case there
must also be a VCAP rule action that sets the counter id.
The Sparx5 IS2 VCAP uses a dedicated counter area with 32bit counters.
This series adds support for getting VCAP rule counters and provide these
via the TC statistic interface.
This only support packet counters, not byte counters.
Finally the series adds support for the ARP frame dissector and configures
the Sparx5 IS2 VCAP to generate the ARP keyset when ARP traffic is
received.
Delivery:
=========
This is current plan for delivering the full VCAP feature set of Sparx5:
- DebugFS support for inspecting rules
- TC protocol all support
- Sparx5 IS0 VCAP support
- TC policer and drop action support (depends on the Sparx5 QoS support
upstreamed separately)
- Sparx5 ES0 VCAP support
- TC flower template support
- TC matchall filter support for mirroring and policing ports
- TC flower filter mirror action support
- Sparx5 ES2 VCAP support

CQE compression feature improves performance by reducing PCI bandwidth

Enhanced CQE compression introduced in ConnectX-6 and it aims to reduce
CPU utilization of SW side packets decompression by eliminating the
need to rewrite ownership bit, which is likely to cost a cache-miss, is
replaced by validity byte handled solely by HW.
Another advantage of the enhanced feature is that session packets are
available to SW as soon as a single CQE slot is filled, instead of
waiting for session to close, this improves packet latency from NIC to
host.
Performance:
Following are tested scenarios and reults comparing basic and enahnced
CQE compression.
setup: IXIA 100GbE connected directly to port 0 and port 1 of
ConnectX-6 Dx 100GbE dual port.
Case #1 RX only, single flow goes to single queue:
IRQ rate reduced by ~ 30%, CPU utilization improved by 2%.
Case #2 IP forwarding from port 1 to port 0 single flow goes to

Case #3 IP forwarding from port 1 to port 0 Max Throughput IXIA sends

====================
dt-bindings: net: qcom,ipa: relax some restrictions
The first patch in this series simply removes an unnecessary
requirement in the IPA binding. Previously, if the modem was doing
GSI firmware loading, the firmware name property was required to
*not* be present. There is no harm in having the firmware name be
specified, so this restriction isn't needed.
The second patch restates a requirement on the "memory-region"
property more accurately.
These binding changes have no impact on existing code or DTS files.
These aren't really bug fixes, so no need to back-port.

dt-bindings: net: qcom,ipa: restate a requirement
Either the AP or modem loads GSI firmware. If the modem-init
property is present, the modem loads it. Otherwise, the AP loads
it, and in that case the memory-region property must be defined.
Currently this requirement is expressed as one or the other of the
modem-init or the memory-region property being required. But it's
harmless for the memory-region to be present if the modem is loading
firmware (it'll just be ignored).
Restate the requirement so that the memory-region property is
required only if modem-init is not present.

If the AP loads GSI firmware, the name of the firmware file to use

Jacob Keller says:
====================
ptp: convert remaining users of .adjfreq
A handful of drivers remain which still use the .adjfreq interface instead
of the newer .adjfine interface. The new interface is preferred as it has a
more precise adjustment using scaled parts per million.
A handful of the remaining drivers are implemented with a common pattern
that can be refactored to use the adjust_by_scaled_ppm and
diff_by_scaled_ppm helper functions. These include the ptp_phc, ptp_ixp64x,
tg3, hclge, stmac, cpts and bnxt drivers. These are each refactored in a
separate change.
The remaining drivers, bnx2x, liquidio, cxgb4, fec, and qede implement
.adjfreq in a way different from the normal pattern expected by
adjust_by_scaled_ppm. Fixing these drivers to properly use .adjfine requires
specific knowledge of the hardware implementation. Instead I simply refactor
them to use .adjfine and convert scaled_ppm into ppb using the
scaled_ppm_to_ppb function.
Finally, the .adjfreq implementation interface is removed entirely. This
simplifies the interface and ensures that new drivers must implement the new
interface as they no longer have an alternative.
This still leaves parts per billion used as part of the max_adj interface,
and the core PTP stack still converts scaled_ppm to ppb to check this. I
plan to investigate fixing this in the future.

Convert all remaining drivers that still use .adjfreq to the newer .adjfine

Add support for xdp in lan966x driver. Currently only XDP_PASS and

Patch 3 actually adds the xdp. Currently the only supported actions
are XDP_PASS and XDP_DROP. In the future this will be extended with
XDP_TX and XDP_REDIRECT.
Patch 4 changes to use page pool API, because the handling of the
pages is similar with what already lan966x driver is doing. In this
way is possible to remove some of the code.

Merge branch 'sparx5-TC-key'
Steen Hegelund says:
====================
Extend TC key support for Sparx5 IS2 VCAP
This provides extended tc flower filter key support for the Sparx5 VCAP
functionality.
It builds on top of the initial IS2 VCAP support found in this series:
https://lore.kernel.org/all/
20221020130904.1215072-1-steen.hegelund@microchip.com/
Overview:
=========
The added flower filter key (dissector) support is this:
- ipv4_addr (sip and dip)
- ipv6_addr (sip and dip)
- control (IPv4 fragments)
- portnum (tcp and udp port numbers)
- basic (L3 and L4 protocol)
- vlan (outer vlan tag info)
- tcp (tcp flags)
- ip (tos field)
The IS2 VCAP supports classified VLAN information which amounts to the
outer VLAN info in case of multiple tags.
Functionality:
==============
Before frames can match IS2 VCAP rules with e.g an IPv4 source address, the
IS2 VCAPs keyset configuration must include keyset that contains a IPv4
source address and this must be configured for the lookup/port/traffic-type
that you want to match on.
The Sparx5 IS2 VCAP has the following traffic types:
- Non-Ethernet frames
- IPv4 Unicast frames
- IPv4 Multicast frames
- IPv6 Unicast frames
- IPv6 Multicast frames
- ARP frames
So to cover IPv4 traffic the two IPv4 categories must be configured with a
keyset that contains IPv4 address information such as the
VCAP_KFS_IP4_TCP_UDP keyset.
The IPv4 and IPv6 traffic types are configured with useful default keysets,
in later series we will use the tc template functionality when we want to
change these defaults.
The flower filter must contain a goto action as its last action and the
chain id must specify the chain id of the next lookup in a VCAP or a
destination outside the VCAP ranges.
To activate the VCAP lookups on a port you must add a TC matchall filter on
the port containing a single goto action that points to the chain id of the
first lookup in the IS2 VCAP.
From then on frames arriving on this port will be matched against the
rules in the IS2 VCAP lookups.
Removing the matchall filter will deactivate the IS2 lookups, but will
leave the VCAP rules in the memory of the VCAP instance, and from then in
frames will no longer be matched against the rules the in IS2 VCAP.
If the matchall rule is added back again the IS2 rules will be active
once more.
Delivery:
=========
This is current plan for delivering the full VCAP feature set of Sparx5:
- TC flower filter statistics and rule order by size and priority
- debugfs support for inspecting rules
- support for TC protocol all
- Sparx5 IS0 VCAP support
- add TC policer and drop action support (depends on the Sparx5 QoS support
upstreamed separately)
- Sparx5 ES0 VCAP support
- TC flower template support
- TC matchall filter support for mirroring and policing ports
- TC flower filter mirror action support
- Sparx5 ES2 VCAP support
Version History:
================
v6 Rebased on the latest next-next master branch.
No other implementation changes.
v5 Add support for a TC matchall filter with a single goto action
which will activate the lookups of the VCAP. Removing this filter
will deactivate the VCAP lookups again.
v4 Add support for TC flower filter goto action and a check of the
actions: check action combinations and the goto chain id.
v3 Add some more details to the explanation in the commit message
about support for MAC_ETYPE keysets and "protocol all" as well as
the classified VLAN information. This is done to help testing the
feature.
No implementation changes in this version.
v2 Split one of the KUNIT tests into 3 tests to fix a kernel robot
build warning.

81000000
Notes:
- The "protocol all" selection is not supported yet.
- The MAC address rule now needs to use non-ip and non "protocol all". Here
is an example:
tc filter add dev eth12 ingress chain 8000000 prio 10 handle 10 \
protocol 0xbeef flower skip_sw \
dst_mac 0a:0b:0c:0d:0e:0f \
src_mac 2:0:0:0:0:1 \
action trap action goto chain
81000000
- The VLAN rules use classified VLAN information, and to get the
classification information into the frame metadata, the ingress port need
to be added to a bridge with the VID and vlan filtering enabled, like
this (using VID 600 and four ports eth12, eth13, eth14 and eth15):
ip link add name br5 type bridge
ip link set dev br5 up
ip link set eth12 master br5
ip link set eth13 master br5
ip link set eth14 master br5
ip link set eth15 master br5

net: microchip: sparx5: Differentiate IPv4 and IPv6 traffic in keyset config
This changes the port keyset configuration for Sparx5 IS2 so that
- IPv4 generates a IP4_TCP_UDP keyset for IPv4 TCP/UDP frames and a
IP4_OTHER keyset for other IPv4 frames (both UC and MC)
- IPv6 generates a IP_7TUPLE keyset (both UC and MC)
ARP and non-IP traffic continues to generate the MAC_ETYPE keyset

Merge branch 'mt7986-WED-RX'
Lorenzo Bianconi says:
====================
introduce WED RX support to MT7986 SoC
Similar to TX counterpart available on MT7622 and MT7986, introduce
RX Wireless Ethernet Dispatch available on MT7986 SoC in order to
offload traffic received by wlan nic to the wired interfaces (lan/wan).
Changes since v3:
- remove reset property in ethsys dts node
- rely on readx_poll_timeout in wo mcu code
- fix typos
- move wo-ccif binding in soc folder
- use reserved-memory for wo-dlm
- improve wo-ccif binding
Changes since v2:
- rely on of_reserved_mem APIs in mcu code
- add some dts fixes
- rename {tx,rx}_wdma in {rx,tx}_wdma
- update entry in maintainers file
Changes since v1:
- fix sparse warnings
- rely on memory-region property in mt7622-wed.yaml
- some more binding fixes
