macb: add zynqmp SGMII dynamic configuration support
This patchset add firmware and driver support to do SD/GEM dynamic
configuration. In traditional flow GEM secure space configuration
is done by FSBL. However in specific usescases like dynamic designs
where GEM is not enabled in base vivado design, FSBL skips GEM
initialization and we need a mechanism to configure GEM secure space
in linux space at runtime.

Add support for the dynamic configuration which takes care of
configuring the GEM secure space configuration registers
using EEMI APIs.
High level sequence is to:
- Check for the PM dynamic configuration support, if no error proceed with
GEM dynamic configurations(next steps) otherwise skip the dynamic
configuration.
- Configure GEM Fixed configurations.
- Configure GEM_CLK_CTRL (gemX_sgmii_mode).
- Trigger GEM reset.

These functions expect to be called from RCU read-side critical section,
but this only happens when invoked from the data path via
ip{,6}_mr_input(). They can also be invoked from process context in
response to user space adding a multicast route which resolves a cache
entry with queued packets [1][2].
Fix by adding missing rcu_read_lock() / rcu_read_unlock() in these call
paths.

IPA can route packets between IPA-connected entities. The AP and
modem are currently the only such entities supported, and no routing
is required to transfer packets between them.
The number of entries in each routing table is fixed, and defined at
initialization time. Some of these entries are designated for use
by the modem, and the rest are available for the AP to use. The AP
sends a QMI message to the modem which describes (among other
things) information about routing table memory available for the
modem to use.
Currently the QMI initialization packet gives wrong information in
its description of routing tables. What *should* be supplied is the
maximum index that the modem can use for the routing table memory
located at a given location. The current code instead supplies the
total *number* of routing table entries. Furthermore, the modem is
granted the entire table, not just the subset it's supposed to use.
This patch fixes this. First, the ipa_mem_bounds structure is
generalized so its "end" field can be interpreted either as a final
byte offset, or a final array index. Second, the IPv4 and IPv6
(non-hashed and hashed) table information fields in the QMI
ipa_init_modem_driver_req structure are changed to be ipa_mem_bounds
rather than ipa_mem_array structures. Third, we set the "end" value
for each routing table to be the last index, rather than setting the
"count" to be the number of indices. Finally, instead of allowing
the modem to use all of a routing table's memory, it is limited to
just the portion meant to be used by the modem. In all versions of
IPA currently supported, that is IPA_ROUTE_MODEM_COUNT (8) entries.
Update a few comments for clarity.

sfp: add support for HALNy GPON module
This series adds support for the HALNy GPON SFP module. In order to do
this sensibly, we need a more flexible quirk system, since we need to
change the behaviour of the SFP cage driver to ignore the LOS and
TX_FAULT signals after module detection.
Since we move the SFP quirks into the SFP cage driver, we can use it
for the MA5671A and 3FE46541AA modules as well.

Re-implement the decision making for soft state polling. Instead of
generating the soft state mask in sfp_soft_start_poll() by looking at
which GPIOs are available, record their availability in
sfp_sm_mod_probe() in sfp->state_hw_mask.
This will then allow us to clear bits in sfp->state_hw_mask in module
specific quirks when the hardware signals should not be used, thereby
allowing us to switch to using the software state polling.

net: ipa: a mix of cleanups
This series contains a set of cleanups done in preparation for a
more substantitive upcoming series that reworks how IPA registers
and their fields are defined.
The first eliminates about half of the possible GSI register
constant symbols by removing offset definitions that are not
currently required.
The next two mainly rearrange code for some common enumerated types.
The next one fixes two spots that reuse local variable names in
inner scopes when defining offsets.
The next adds some additional restrictions on the value held in a
register.
And the last one just fixes two field mask symbol names so they
adhere to the common naming convention.

In ipa_endpoint_init_hdr(), as well as ipa_endpoint_init_hdr_ext(),
a top-level automatic variable named "offset" is used to represent
the offset of a register.
However, deeper within each of those functions is *another*
definition of a local variable with the same name, representing
something else. Scoping rules ensure the result is what was
intended, but this variable name reuse is bad practice and makes
the code confusing.
Fix this by naming the inner variable "off". Use "off" instead of
"checksum_offset" in ipa_endpoint_init_cfg() for consistency.

Move the definition of the gsi_ee_id enumerated type out of "gsi.h"

definition of the ipa_version enumerated type, allowing it to be

gsi_ee_id, and moving it here makes it easier to get only that
definition without everything else defined in "gsi.h".

Each GSI execution environment (EE) is able to access many of the
GSI registers associated with the other EEs. A block of GSI
registers is contained within a region of memory, and an EE's
register offset can be determined by adding the register's base
offset to the product of the EE ID and a fixed constant.
Despite this possibility, the AP IPA code *never* accesses any GSI
registers other than its own. So there's no need to define the
macros that compute register offsets for other EEs.
Redefine the AP access macros to compute the offset the way the more
general "any EE" macro would, and get rid of the unneeded macros.

net: ethernet: adi: Add ADIN1110 support
The ADIN1110 is a low power single port 10BASE-T1L MAC-PHY
designed for industrial Ethernet applications. It integrates
an Ethernet PHY core with a MAC and all the associated analog
circuitry, input and output clock buffering.
ADIN1110 MAC-PHY encapsulates the ADIN1100 PHY. The PHY registers
can be accessed through the MDIO MAC registers.
We are registering an MDIO bus with custom read/write in order
to let the PHY to be discovered by the PAL. This will let
the ADIN1100 Linux driver to probe and take control of
the PHY.
The ADIN2111 is a low power, low complexity, two-Ethernet ports
switch with integrated 10BASE-T1L PHYs and one serial peripheral
interface (SPI) port.
The device is designed for industrial Ethernet applications using
low power constrained nodes and is compliant with the IEEE 802.3cg-2019
Ethernet standard for long reach 10 Mbps single pair Ethernet (SPE).
The switch supports various routing configurations between
the two Ethernet ports and the SPI host port providing a flexible
solution for line, daisy-chain, or ring network topologies.
The ADIN2111 supports cable reach of up to 1700 meters with ultra
low power consumption of 77 mW. The two PHY cores support the
1.0 V p-p operating mode and the 2.4 V p-p operating mode defined
in the IEEE 802.3cg standard.
The device integrates the switch, two Ethernet physical layer (PHY)
cores with a media access control (MAC) interface and all the
associated analog circuitry, and input and output clock buffering.
The device also includes internal buffer queues, the SPI and
subsystem registers, as well as the control logic to manage the reset
and clock control and hardware pin configuration.
Access to the PHYs is exposed via an internal MDIO bus. Writes/reads
can be performed by reading/writing to the ADIN2111 MDIO registers
via SPI.
On probe, for each port, a struct net_device is allocated and
registered. When both ports are added to the same bridge, the driver
will enable offloading of frame forwarding at the hardware level.
Driver offers STP support. Normal operation on forwarding state.
Allows only frames with the 802.1d DA to be passed to the host
when in any of the other states.
When both ports of ADIN2111 belong to the same SW bridge a maximum
of 12 FDB entries will offloaded by the hardware and are marked as such.

Before we switched to ->read_skb(), ->read_sock() was passed with
desc.count=1, which technically indicates we only read one skb per
->sk_data_ready() call. However, for TCP, this is not true.
TCP at least has sk_rcvlowat which intentionally holds skb's in
receive queue until this watermark is reached. This means when
->sk_data_ready() is invoked there could be multiple skb's in the
queue, therefore we have to read multiple skbs in tcp_read_skb()
instead of one.

====================
seg6: add NEXT-C-SID support for SRv6 End behavior
The Segment Routing (SR) architecture is based on loose source routing.
A list of instructions, called segments, can be added to the packet headers to
influence the forwarding and processing of the packets in an SR enabled
network.
In SRv6 (Segment Routing over IPv6 data plane) [1], the segment identifiers
(SIDs) are IPv6 addresses (128 bits) and the segment list (SID List) is carried
in the Segment Routing Header (SRH). A segment may correspond to a "behavior"
that is executed by a node when the packet is received.
The Linux kernel currently supports a large subset of the behaviors described
in [2] (e.g., End, End.X, End.T and so on).
Some SRv6 scenarios (i.e.: traffic-engineering, fast-rerouting, VPN, mobile
network backhaul, etc.) may require a large number of segments (i.e. up to 15).
Therefore, reducing the size of the SID List is useful to minimize the impact
on MTU (Maximum Transfer Unit) and to enable SRv6 on legacy hardware devices
with limited processing power that can suffer from long IPv6 headers.
Draft-ietf-spring-srv6-srh-compression [3] extends the SRv6 architecture by
providing different mechanisms for the efficient representation (i.e.
compression) of the SID List.
The NEXT-C-SID mechanism described in [3] offers the possibility of encoding
several SRv6 segments within a single 128 bit SID address. Such a SID address
is called a Compressed SID Container. In this way, the length of the SID List
can be drastically reduced. In some cases, the SRH can be omitted, as the IPv6
Destination Address can carry the whole Segment List, using its compressed
representation.
The NEXT-C-SID mechanism relies on the "flavors" framework defined in [2].
The flavors represent additional operations that can modify or extend a subset
of the existing behaviors.
In this patchset we extend the SRv6 Subsystem in order to support the
NEXT-C-SID mechanism.
In details the patchset is made of:
- patch 1/3: add netlink_ext_ack support in parsing SRv6 behavior attributes;
- patch 2/3: add NEXT-C-SID support for SRv6 End behavior;
- patch 3/3: add selftest for NEXT-C-SID in SRv6 End behavior.
The corresponding iproute2 patch for supporting the NEXT-C-SID in SRv6 End
behavior is provided in a separated patchset.
Comments, improvements and suggestions are always appreciated.

This selftest is designed for testing the support of NEXT-C-SID flavor
for SRv6 End behavior. It instantiates a virtual network composed of
several nodes: hosts and SRv6 routers. Each node is realized using a
network namespace that is properly interconnected to others through veth
pairs.
The test considers SRv6 routers implementing IPv4/IPv6 L3 VPNs leveraged
by hosts for communicating with each other. Such routers i) apply
different SRv6 Policies to the traffic received from connected hosts,
considering the IPv4 or IPv6 protocols; ii) use the NEXT-C-SID
compression mechanism for encoding several SRv6 segments within a single
128-bit SID address, referred to as a Compressed SID (C-SID) container.
The NEXT-C-SID is provided as a "flavor" of the SRv6 End behavior,
enabling it to properly process the C-SID containers. The correct
execution of the enabled NEXT-C-SID SRv6 End behavior is verified
through reachability tests carried out between hosts belonging to the
same VPN.

The NEXT-C-SID mechanism described in [1] offers the possibility of
encoding several SRv6 segments within a single 128 bit SID address. Such
a SID address is called a Compressed SID (C-SID) container. In this way,
the length of the SID List can be drastically reduced.
A SID instantiated with the NEXT-C-SID flavor considers an IPv6 address
logically structured in three main blocks: i) Locator-Block; ii)
Locator-Node Function; iii) Argument.
C-SID container
+------------------------------------------------------------------+
| Locator-Block |Loc-Node| Argument |
| |Function| |
+------------------------------------------------------------------+
<--------- B -----------> <- NF -> <------------- A --------------->
(i) The Locator-Block can be any IPv6 prefix available to the provider;
(ii) The Locator-Node Function represents the node and the function to
be triggered when a packet is received on the node;
(iii) The Argument carries the remaining C-SIDs in the current C-SID
container.
The NEXT-C-SID mechanism relies on the "flavors" framework defined in
[2]. The flavors represent additional operations that can modify or
extend a subset of the existing behaviors.
This patch introduces the support for flavors in SRv6 End behavior
implementing the NEXT-C-SID one. An SRv6 End behavior with NEXT-C-SID
flavor works as an End behavior but it is capable of processing the
compressed SID List encoded in C-SID containers.
An SRv6 End behavior with NEXT-C-SID flavor can be configured to support
user-provided Locator-Block and Locator-Node Function lengths. In this
implementation, such lengths must be evenly divisible by 8 (i.e. must be
byte-aligned), otherwise the kernel informs the user about invalid
values with a meaningful error code and message through netlink_ext_ack.
If Locator-Block and/or Locator-Node Function lengths are not provided
by the user during configuration of an SRv6 End behavior instance with
NEXT-C-SID flavor, the kernel will choose their default values i.e.,
32-bit Locator-Block and 16-bit Locator-Node Function.

An SRv6 behavior instance can be set up using mandatory and/or optional
attributes.
In the setup phase, each supplied attribute is parsed and processed. If
the parsing operation fails, the creation of the behavior instance stops
and an error number/code is reported to the user. In many cases, it is
challenging for the user to figure out exactly what happened by relying
only on the error code.
For this reason, we add the support for netlink_ext_ack in parsing SRv6
behavior attributes. In this way, when an SRv6 behavior attribute is
parsed and an error occurs, the kernel can send a message to the
userspace describing the error through a meaningful text message in
addition to the classic error code.

Maximum frame length check is enabled in lan937x switch on POR, But it
is found to be disabled on driver during port setup operation. Due to
this, packets are not dropped when transmitted with greater than configured
value. For testing, setup made for lan1->lan2 transmission and configured
lan1 interface with a frame length (less than 1500 as mentioned in
documentation) and transmitted packets with greater than configured value.
Expected no packets at lan2 end, but packets observed at lan2.
Based on the documentation, packets should get discarded if the actual
packet length doesn't match the frame length configured. Frame length check
should be disabled only for cascaded ports due to tailtags.
This feature was disabled on ksz9477 series due to ptp issue, which is
not in lan937x series. But since lan937x took ksz9477 as base, frame
length check disabled here as well. Patch added to remove this portion
from port setup so that maximum frame length check will be active for
normal ports.

Beginning of the merge window we introduced the vfs{g,u}id_t types in
b27c82e12965 ("attr: port attribute changes to new types") and changed
various codepaths over including chown_common().
During that change we forgot to account for the case were the passed
ownership value is -1. In this case the ownership fields in struct iattr
aren't initialized but we rely on them being initialized by the time we
generate the ownership to pass down to the LSMs. All the major LSMs
don't care about the ownership values at all. Only Tomoyo uses them and
so it took a while for syzbot to unearth this issue.
Fix this by initializing the ownership fields and do it within the
retry_deleg block. While notify_change() doesn't alter the ownership
fields currently we shouldn't rely on it.
Since no kernel has been released with these changes this does not
needed to be backported to any stable kernels.

====================
DSA changes for multiple CPU ports (part 4)

will know that I am trying to enable the second internal port pair from
the NXP LS1028A Felix switch for DSA-tagged traffic via "ocelot-8021q".
This series represents the final part of that effort. We have:
- the introduction of new UAPI in the form of IFLA_DSA_MASTER, the
iproute2 patch for which is here:
https://patchwork.kernel.org/project/netdevbpf/patch/20220904190025.813574-1-vladimir.oltean@nxp.com/
- preparation for LAG DSA masters in terms of suppressing some
operations for masters in the DSA core that simply don't make sense
when those masters are a bonding/team interface
- handling all the net device events that occur between DSA and a
LAG DSA master, including migration to a different DSA master when the
current master joins a LAG, or the LAG gets destroyed
- updating documentation
- adding an implementation for NXP LS1028A, where things are insanely
complicated due to hardware limitations. We have 2 tagging protocols:
* the native "ocelot" protocol (NPI port mode). This does not support
CPU ports in a LAG, and supports a single DSA master. The DSA master
can be changed between eno2 (2.5G) and eno3 (1G), but all ports must
be down during the changing process, and user ports assigned to the
old DSA master will refuse to come up if the user requests that
during a "transient" state.
* the "ocelot-8021q" software-defined protocol, where the Ethernet
ports connected to the CPU are not actually "god mode" ports as far
as the hardware is concerned. So here, static assignment between
user and CPU ports is possible by editing the PGID_SRC masks for
the port-based forwarding matrix, and "CPU ports in a LAG" simply
means "a LAG like any other".
The series was regression-tested on LS1028A using the local_termination.sh
kselftest, in most of the possible operating modes and tagging protocols.
I have not done a detailed performance evaluation yet, but using LAG, is
possible to exceed the termination bandwidth of a single CPU port in an
iperf3 test with multiple senders and multiple receivers.

Changing the DSA master means different things depending on the tagging
protocol in use.
For NPI mode ("ocelot" and "seville"), there is a single port which can
be configured as NPI, but DSA only permits changing the CPU port
affinity of user ports one by one. So changing a user port to a
different NPI port globally changes what the NPI port is, and breaks the
user ports still using the old one.
To address this while still permitting the change of the NPI port,
require that the user ports which are still affine to the old NPI port
are down, and cannot be brought up until they are all affine to the same
NPI port.
The tag_8021q mode ("ocelot-8021q") is more flexible, in that each user
port can be freely assigned to one CPU port or to the other. This works
by filtering host addresses towards both tag_8021q CPU ports, and then
restricting the forwarding from a certain user port only to one of the
two tag_8021q CPU ports.
Additionally, the 2 tag_8021q CPU ports can be placed in a LAG. This
works by enabling forwarding via PGID_SRC from a certain user port
towards the logical port ID containing both tag_8021q CPU ports, but
then restricting forwarding per packet, via the LAG hash codes in
PGID_AGGR, to either one or the other.
When we change the DSA master to a LAG device, DSA guarantees us that
the LAG has at least one lower interface as a physical DSA master.
But DSA masters can come and go as lowers of that LAG, and
ds->ops->port_change_master() will not get called, because the DSA
master is still the same (the LAG). So we need to hook into the
ds->ops->port_lag_{join,leave} calls on the CPU ports and update the
logical port ID of the LAG that user ports are assigned to.

There are 2 ways in which a DSA user port may become handled by 2 CPU
ports in a LAG:
(1) its current DSA master joins a LAG
ip link del bond0 && ip link add bond0 type bond mode 802.3ad
ip link set eno2 master bond0
When this happens, all user ports with "eno2" as DSA master get
automatically migrated to "bond0" as DSA master.
(2) it is explicitly configured as such by the user
# Before, the DSA master was eno3
ip link set swp0 type dsa master bond0
The design of this configuration is that the LAG device dynamically
becomes a DSA master through dsa_master_setup() when the first physical
DSA master becomes a LAG slave, and stops being so through
dsa_master_teardown() when the last physical DSA master leaves.
A LAG interface is considered as a valid DSA master only if it contains
existing DSA masters, and no other lower interfaces. Therefore, we
mainly rely on method (1) to enter this configuration.
Each physical DSA master (LAG slave) retains its dev->dsa_ptr for when
it becomes a standalone DSA master again. But the LAG master also has a
dev->dsa_ptr, and this is actually duplicated from one of the physical
LAG slaves, and therefore needs to be balanced when LAG slaves come and
go.
To the switch driver, putting DSA masters in a LAG is seen as putting
their associated CPU ports in a LAG.
We need to prepare cross-chip host FDB notifiers for CPU ports in a LAG,
by calling the driver's ->lag_fdb_add method rather than ->port_fdb_add.

Drivers could refuse to offload a LAG configuration for a variety of
reasons, mainly having to do with its TX type. Additionally, since DSA
masters may now also be LAG interfaces, and this will translate into a
call to port_lag_join on the CPU ports, there may be extra restrictions
there. Propagate the netlink extack to this DSA method in order for
drivers to give a meaningful error message back to the user.
