mlxsw: Preparations for line cards support
Currently, mlxsw registers thermal zones as well as hwmon entries for
objects such as transceiver modules and gearboxes. In upcoming modular
systems, these objects are no longer found on the main board (i.e., slot
0), but on plug-able line cards. This patchset prepares mlxsw for such
systems in terms of hwmon, thermal and cable access support.
Patches #1-#3 gradually prepare mlxsw for transceiver modules access
support for line cards by splitting some of the internal structures and
some APIs.
Patches #4-#5 gradually prepare mlxsw for hwmon support for line cards
by splitting some of the internal structures and augmenting them with a
slot index.
Patches #6-#7 do the same for thermal zones.
Patch #8 selects cooling device for binding to a thermal zone by exact
name match to prevent binding to non-relevant devices.
Patch #9 replaces internal define for thermal zone name length with a
common define.

Introduce intermediate level for thermal zones areas.
Currently all thermal zones are associated with thermal objects located
within the main board. Such objects are created during driver
initialization and removed during driver de-initialization.
For line cards in modular system the thermal zones are to be associated
with the specific line card. They should be created whenever new line
card is available (inserted, validated, powered and enabled) and
removed, when line card is getting unavailable.
The thermal objects found on the line card #n are accessed by setting
slot index to #n, while for access to objects found on the main board
slot index should be set to default value zero.
Each thermal area contains the set of thermal zones associated with
particular slot index.
Thus introduction of thermal zone areas allows to use the same APIs for
the main board and line cards, by adding slot index argument.

Currently, mlxsw supports a single hwmon device and registers it with
attributes corresponding to the various objects found on the main
board such as fans and gearboxes.
Line cards can have the same objects, but unlike the main board they
can be added and removed while the system is running. The various
hwmon objects found on these line cards should be created when the
line card becomes available and destroyed when the line card becomes
unavailable.
The above can be achieved by representing each line card as a
different hwmon device and registering / unregistering it when the
line card becomes available / unavailable.
Prepare for multi hwmon device support by splitting
'struct mlxsw_hwmon' into 'struct mlxsw_hwmon' and
'struct mlxsw_hwmon_dev'. The first will hold information relevant to
all hwmon devices, whereas the second will hold per-hwmon device
information.

rndis_host: handle bogus MAC addresses in ZTE RNDIS devices
When porting support of ZTE MF286R to OpenWrt [1], it was discovered,
that its built-in LTE modem fails to adjust its target MAC address,
when a random MAC address is assigned to the interface, due to detection of
"locally-administered address" bit. This leads to dropping of ingress
trafficat the host. The modem uses RNDIS as its primary interface,
with some variants exposing both of them simultaneously.
Then it was discovered, that cdc_ether driver contains a fixup for that
exact issue, also appearing on CDC ECM interfaces.
I discussed how to proceed with that with Bjørn Mork at OpenWrt forum [3],
with the first approach would be to trust the locally-administered MAC
again, and add a quirk for the problematic ZTE devices, as suggested by
Kristian Evensen. before [4], but reusing the fixup from cdc_ether looks
like a safer and more generic solution.
Finally, according to Bjørn's suggestion. limit the scope of bogus MAC
addressdetection to ZTE devices, the same way as it is done in cdc_ether,
as this trait wasn't really observed outside of ZTE devices.
Do that for both flavours of RNDIS devices, with interface classes
02/02/ff and e0/01/03, as both types are reported by different modems.

Certain ZTE modems, namely: MF823. MF831, MF910, built-in modem from
MF286R, expose both CDC-ECM and RNDIS network interfaces.
They have a trait of ignoring the locally-administered MAC address
configured on the interface both in CDC-ECM and RNDIS part,
and this leads to dropping of incoming traffic by the host.
However, the workaround was only present in CDC-ECM, and MF286R
explicitly requires it in RNDIS mode.
Re-use the workaround in rndis_host as well, to fix operation of MF286R
module, some versions of which expose only the RNDIS interface. Do so by
introducing new flag, RNDIS_DRIVER_DATA_DST_MAC_FIXUP, and testing for it
in rndis_rx_fixup. This is required, as RNDIS uses frame batching, and all
of the packets inside the batch need the fixup. This might introduce a
performance penalty, because test is done for every returned Ethernet
frame.
Apply the workaround to both "flavors" of RNDIS interfaces, as older ZTE
modems, like MF823 found in the wild, report the USB_CLASS_COMM class
interfaces, while MF286R reports USB_CLASS_WIRELESS_CONTROLLER.

When L3 stats are disabled, rtnl_offload_xstats_get_size_stats() returns
size of 0, which is supposed to be an indication that the corresponding
attribute should not be emitted. However, instead, the current code
reserves a 0-byte attribute.
The reason this does not show up as a citation on a kasan kernel is that
netdev_offload_xstats_get(), which is supposed to fill in the data, never
ends up getting called, because rtnl_offload_xstats_get_stats() notices
that the stats are not actually used and skips the call.
Thus a zero-length IFLA_OFFLOAD_XSTATS_L3_STATS attribute ends up in a
response, confusing the userspace.
Fix by skipping the L3-stats related block in rtnl_offload_xstats_fill().

When the device tree has 2 CPU ports defined, a single one is active
(has any dp->cpu_dp pointers point to it). Yet the second one is still a
CPU port, and DSA still calls ->change_tag_protocol on it.
On the NXP LS1028A, the CPU ports are ports 4 and 5. Port 4 is the
active CPU port and port 5 is inactive.
After the following commands:
# Initial setting
cat /sys/class/net/eno2/dsa/tagging
ocelot
echo ocelot-8021q > /sys/class/net/eno2/dsa/tagging
echo ocelot > /sys/class/net/eno2/dsa/tagging
traffic is now broken, because the driver has moved the NPI port from
port 4 to port 5, unbeknown to DSA.
The problem can be avoided by detecting that the second CPU port is
unused, and not doing anything for it. Further rework will be needed
when proper support for multiple CPU ports is added.
Treat this as a bug and prepare current kernels to work in single-CPU
mode with multiple-CPU DT blobs.

The kernel test robot reported a build failure:
or1k-linux-ld: drivers/net/dsa/realtek/realtek-smi.o:(.rodata+0x16c): undefined reference to `rtl8366rb_variant'
... with the following build configuration:
CONFIG_NET_DSA_REALTEK=y
CONFIG_NET_DSA_REALTEK_SMI=y
CONFIG_NET_DSA_REALTEK_RTL8365MB=y
CONFIG_NET_DSA_REALTEK_RTL8366RB=m
The problem here is that the realtek-smi interface driver gets built-in,
while the rtl8366rb switch subdriver gets built as a module, hence the
symbol rtl8366rb_variant is not reachable when defining the OF device
table in the interface driver.
The Kconfig dependencies don't help in this scenario because they just
say that the subdriver(s) depend on at least one interface driver. In
fact, the subdrivers don't depend on the interface drivers at all, and
can even be built even in their absence. Somewhat strangely, the
interface drivers can also be built in the absence of any subdriver,
BUT, if a subdriver IS enabled, then it must be reachable according to
the linkage of the interface driver: effectively what the IS_REACHABLE()
macro achieves. If it is not reachable, the above kind of linker error
will be observed.
Rather than papering over the above build error by simply using
IS_REACHABLE(), we can do a little better and admit that it is actually
the interface drivers that have a dependency on the subdrivers. So this
patch does exactly that. Specifically, we ensure that:
1. The interface drivers' Kconfig symbols must have a value no greater
than the value of any subdriver Kconfig symbols.
2. The subdrivers should by default enable both interface drivers, since
most users probably want at least one of them; those interface
drivers can be explicitly disabled however.
What this doesn't do is prevent a user from building only a subdriver,
without any interface driver. To that end, add an additional line of
help in the menu to guide users in the right direction.

net: ip: add skb drop reasons to ip ingress
In the series "net: use kfree_skb_reason() for ip/udp packet receive",
skb drop reasons are added to the basic ingress path of IPv4. And in
the series "net: use kfree_skb_reason() for ip/neighbour", the egress
paths of IPv4 and IPv6 are handled. Related links:
https://lore.kernel.org/netdev/20220205074739.543606-1-imagedong@tencent.com/https://lore.kernel.org/netdev/20220226041831.2058437-1-imagedong@tencent.com/
Seems we still have a lot work to do with IP layer, including IPv6 basic
ingress path, IPv4/IPv6 forwarding, IPv6 exthdrs, fragment and defrag,
etc.
In this series, skb drop reasons are added to the basic ingress path of
IPv6 protocol and IPv4/IPv6 packet forwarding. Following functions, which
are used for IPv6 packet receiving are handled:
ip6_pkt_drop()
ip6_rcv_core()
ip6_protocol_deliver_rcu()
And following functions that used for IPv6 TLV parse are handled:
ip6_parse_tlv()
ipv6_hop_ra()
ipv6_hop_ioam()
ipv6_hop_jumbo()
ipv6_hop_calipso()
ipv6_dest_hao()
Besides, ip_forward() and ip6_forward(), which are used for IPv4/IPv6
forwarding, are also handled. And following new drop reasons are added:
/* host unreachable, corresponding to IPSTATS_MIB_INADDRERRORS */
SKB_DROP_REASON_IP_INADDRERRORS
/* network unreachable, corresponding to IPSTATS_MIB_INADDRERRORS */
SKB_DROP_REASON_IP_INNOROUTES
/* packet size is too big, corresponding to
* IPSTATS_MIB_INTOOBIGERRORS
*/
SKB_DROP_REASON_PKT_TOO_BIG
In order to simply the definition and assignment for
'enum skb_drop_reason', some helper functions are introduced in the 1th
patch. I'm not such if this is necessary, but it makes the code simpler.
For example, we can replace the code:
if (reason == SKB_DROP_REASON_NOT_SPECIFIED)
reason = SKB_DROP_REASON_IP_INHDR;
with:
SKB_DR_OR(reason, IP_INHDR);
In the 6th patch, the statistics for skb in ipv6_hop_jum() is removed,
as I think it is redundant. There are two call chains for
ipv6_hop_jumbo(). The first one is:
ipv6_destopt_rcv() -> ip6_parse_tlv() -> ipv6_hop_jumbo()
On this call chain, the drop statistics will be done in
ipv6_destopt_rcv() with 'IPSTATS_MIB_INHDRERRORS' if ipv6_hop_jumbo()
returns false.
The second call chain is:
ip6_rcv_core() -> ipv6_parse_hopopts() -> ip6_parse_tlv()
And the drop statistics will also be done in ip6_rcv_core() with
'IPSTATS_MIB_INHDRERRORS' if ipv6_hop_jumbo() returns false.
Therefore, the statistics in ipv6_hop_jumbo() is redundant, which
means the drop is counted twice. The statistics in ipv6_hop_jumbo()
is almost the same as the outside, except the
'IPSTATS_MIB_INTRUNCATEDPKTS', which seems that we have to ignore it.
======================================================================
Here is a basic test for IPv6 forwarding packet drop that monitored by
'dropwatch' tool:
drop at: ip6_forward+0x81a/0xb70 (0xffffffff86c73f8a)
origin: software
input port ifindex: 7
timestamp: Wed Apr 13 11:51:06 2022 130010176 nsec
protocol: 0x86dd
length: 94
original length: 94
drop reason: IP_INADDRERRORS
The origin cause of this case is that IPv6 doesn't allow to forward the
packet with LOCAL-LINK saddr, and results the 'IP_INADDRERRORS' drop
reason.

Most skb drops during this process are regarded as 'InHdrErrors',

which make we use 'SKB_DROP_REASON_IP_INHDR' correspondingly.
However, 'IP_INHDR' is a relatively general reason. Therefore, we

'SKB_DROP_REASON_UNHANDLED_PROTO' is used for unknown TLV options.
