On some platforms, 100/1000/2500 speeds seem to have sometimes problems
reporting false positive tx unit hang during stressful UDP traffic. Likely
other Intel drivers introduce responses to a tx hang. Update the 'tx hang'
comparator with the comparison of the head and tail of ring pointers and
restore the tx_timeout_factor to the previous value (one).

This can be test by using netperf or iperf3 applications.
Example:
iperf3 -s -p 5001
iperf3 -c 192.168.0.2 --udp -p 5001 --time 600 -b 0

netserver -p 16604
netperf -H 192.168.0.2 -l 600 -p 16604 -t UDP_STREAM -- -m 64000

After calling irq_set_affinity_and_hint(), the cpumask pointer is
saved in desc->affinity_hint, and will be used later when reading
/proc/irq/<num>/affinity_hint. So the cpumask variable needs to be
persistent. Otherwise, we are accessing freed memory when reading
the affinity_hint file.

Also, need to clear affinity_hint before free_irq(), otherwise there
is a one-time warning and stack trace during module unloading:

The ISO 11783-5 standard, in "4.5.2 - Address claim requirements", states:
  d) No CF shall begin, or resume, transmission on the network until 250
     ms after it has successfully claimed an address except when
     responding to a request for address-claimed.

But "Figure 6" and "Figure 7" in "4.5.4.2 - Address-claim
prioritization" show that the CF begins the transmission after 250 ms
from the first AC (address-claimed) message even if it sends another AC
message during that time window to resolve the address contention with
another CF.

As stated in "4.4.2.3 - Address-claimed message":
  In order to successfully claim an address, the CF sending an address
  claimed message shall not receive a contending claim from another CF
  for at least 250 ms.

As stated in "4.4.3.2 - NAME management (NM) message":
  1) A commanding CF can
     d) request that a CF with a specified NAME transmit the address-
        claimed message with its current NAME.
  2) A target CF shall
     d) send an address-claimed message in response to a request for a
        matching NAME

Taking the above arguments into account, the 250 ms wait is requested
only during network initialization.

Do not restart the timer on AC message if both the NAME and the address
match and so if the address has already been claimed (timer has expired)
or the AC message has been sent to resolve the contention with another
CF (timer is still running).

Currently only the network namespace of devlink instance is monitored
for port events. If netdev is moved to a different namespace and then
unregistered, NETDEV_PRE_UNINIT is missed which leads to trigger
following WARN_ON in devl_port_unregister().
WARN_ON(devlink_port->type != DEVLINK_PORT_TYPE_NOTSET);

Fix this by changing the netdev notifier from per-net to global so no
event is missed.

We have two IS1 filters of the OCELOT_VCAP_KEY_ANY key type (the one with
"action vlan pop" and the one with "action vlan modify") and one of the
OCELOT_VCAP_KEY_IPV4 key type (the one with "action skbedit priority").
But we have no IS1 filter with the OCELOT_VCAP_KEY_ETYPE key type, and
there was an uncaught breakage there.

To increase test coverage, convert one of the OCELOT_VCAP_KEY_ANY
filters to OCELOT_VCAP_KEY_ETYPE, by making the filter also match on the
MAC SA of the traffic sent by mausezahn, $h1_mac.

Alternative short title: don't instruct the hardware to match on
EtherType with "protocol 802.1Q" flower filters. It doesn't work for the
reasons detailed below.

With a command such as the following:

tc filter add dev $swp1 ingress chain $(IS1 2) pref 3 \
	protocol 802.1Q flower skip_sw vlan_id 200 src_mac $h1_mac \
	action vlan modify id 300 \
	action goto chain $(IS2 0 0)

the created filter is set by ocelot_flower_parse_key() to be of type
OCELOT_VCAP_KEY_ETYPE, and etype is set to {value=0x8100, mask=0xffff}.
This gets propagated all the way to is1_entry_set() which commits it to
hardware (the VCAP_IS1_HK_ETYPE field of the key). Compare this to the
case where src_mac isn't specified - the key type is OCELOT_VCAP_KEY_ANY,
and is1_entry_set() doesn't populate VCAP_IS1_HK_ETYPE.

The problem is that for VLAN-tagged frames, the hardware interprets the
ETYPE field as holding the encapsulated VLAN protocol. So the above
filter will only match those packets which have an encapsulated protocol
of 0x8100, rather than all packets with VLAN ID 200 and the given src_mac.

The reason why this is allowed to occur is because, although we have a
block of code in ocelot_flower_parse_key() which sets "match_protocol"
to false when VLAN keys are present, that code executes too late.
There is another block of code, which executes for Ethernet addresses,
and has a "goto finished_key_parsing" and skips the VLAN header parsing.
By skipping it, "match_protocol" remains with the value it was
initialized with, i.e. "true", and "proto" is set to f->common.protocol,
or 0x8100.

The concept of ignoring some keys rather than erroring out when they are
present but can't be offloaded is dubious in itself, but is present
since the initial commit fe3490e6 ("net: mscc: ocelot: Hardware
ofload for tc flower filter"), and it's outside of the scope of this
patch to change that.

The problem was introduced when the driver started to interpret the
flower filter's protocol, and populate the VCAP filter's ETYPE field
based on it.

To fix this, it is sufficient to move the code that parses the VLAN keys
earlier than the "goto finished_key_parsing" instruction. This will
ensure that if we have a flower filter with both VLAN and Ethernet
address keys, it won't match on ETYPE 0x8100, because the VLAN key
parsing sets "match_protocol = false".

Frank reports that in a mt7530 setup where some ports are standalone and
some are in a VLAN-aware bridge, 8021q uppers of the standalone ports
lose their VLAN tag on xmit, as seen by the link partner.

This seems to occur because once the other ports join the VLAN-aware
bridge, mt7530_port_vlan_filtering() also calls
mt7530_port_set_vlan_aware(ds, cpu_dp->index), and this affects the way
that the switch processes the traffic of the standalone port.

Relevant is the PVC_EG_TAG bit. The MT7530 documentation says about it:

EG_TAG: Incoming Port Egress Tag VLAN Attribution
0: disabled (system default)
1: consistent (keep the original ingress tag attribute)

My interpretation is that this setting applies on the ingress port, and
"disabled" is basically the normal behavior, where the egress tag format
of the packet (tagged or untagged) is decided by the VLAN table
(MT7530_VLAN_EGRESS_UNTAG or MT7530_VLAN_EGRESS_TAG).

But there is also an option of overriding the system default behavior,
and for the egress tagging format of packets to be decided not by the
VLAN table, but simply by copying the ingress tag format (if ingress was
tagged, egress is tagged; if ingress was untagged, egress is untagged;
aka "consistent). This is useful in 2 scenarios:

- VLAN-unaware bridge ports will always encounter a miss in the VLAN
  table. They should forward a packet as-is, though. So we use
  "consistent" there. See commit e045124e ("net: dsa: mt7530: fix
  tagged frames pass-through in VLAN-unaware mode").

- Traffic injected from the CPU port. The operating system is in god
  mode; if it wants a packet to exit as VLAN-tagged, it sends it as
  VLAN-tagged. Otherwise it sends it as VLAN-untagged*.

*This is true only if we don't consider the bridge TX forwarding offload
feature, which mt7530 doesn't support.

So for now, make the CPU port always stay in "consistent" mode to allow
software VLANs to be forwarded to their egress ports with the VLAN tag
intact, and not stripped.

If the user turns on the vf-true-promiscuous-support flag, then Rx VLAN
filtering will be disabled if the VF requests to enable promiscuous
mode. When the VF is in a port VLAN, this is the incorrect behavior
because it will allow the VF to receive traffic outside of its port VLAN
domain. Fortunately this only resulted in the VF(s) receiving broadcast
traffic outside of the VLAN domain because all of the VLAN promiscuous
rules are based on the port VLAN ID. Fix this by setting the
.disable_rx_filtering VLAN op to a no-op when a port VLAN is enabled on
the VF.

Also, make sure to make this fix for both Single VLAN Mode and Double
VLAN Mode enabled devices.

When both ice and the irdma driver are loaded, a warning in

workqueue being allocated with the WQ_MEM_RECLAIM flag and the irdma one
is not.

According to kernel documentation, this flag should be set if the

Since it is not, there is no need for the ice driver's WQ to have this

Check all ports instead of just port_count ports. PTP init was only
checking ports 0 to port_count. If the hardware ports are not mapped
starting from 0 then they would be missed, e.g. if only ports 20-30 were
mapped it would attempt to init ports 0-10, resulting in NULL pointers
when attempting to timestamp. Now it will init all mapped ports.

Since commit 58e0be1e ("net: use struct_group to copy ip/ipv6
header addresses"), ip and ipv6 headers started to use the __struct_group
definition, which is defined at include/uapi/linux/stddef.h. However,
linux/stddef.h isn't explicitly included in include/uapi/linux/{ip,ipv6}.h,
which breaks build of xskxceiver bpf selftest if you install the uapi
headers in the system:

Entries can linger in cache without timer for days, thanks to
the gc_thresh1 limit. As result, without traffic, the confirmed
time can be outdated and to appear to be in the future. Later,
on traffic, NUD_STALE entries can switch to NUD_DELAY and start
the timer which can see the invalid confirmed time and wrongly
switch to NUD_REACHABLE state instead of NUD_PROBE. As result,
timer is set many days in the future. This is more visible on
32-bit platforms, with higher HZ value.

Why this is a problem? While we expect unused entries to expire,
such entries stay in REACHABLE state for too long, locked in
cache. They are not expired normally, only when cache is full.

Problem and the wrong state change reported by Zhang Changzhong:

172.16.1.18 dev bond0 lladdr 0a:0e:0f:01:12:01 ref 1 used 350521/15994171/350520 probes 4 REACHABLE

350520 seconds have elapsed since this entry was last updated, but it is
still in the REACHABLE state (base_reachable_time_ms is 30000),
preventing lladdr from being updated through probe.

Fix it by ensuring timer is started with valid used/confirmed
times. Considering the valid time range is LONG_MAX jiffies,
we try not to go too much in the past while we are in
DELAY/PROBE state. There are also places that need
used/updated times to be validated while timer is not running.

After calling fwnode_phy_find_device(), the phy device refcount is
incremented. Then, when the phy device is attached to a netdev with
phy_attach_direct(), the refcount is also incremented but only
decremented in the caller if phy_attach_direct() fails. Move
phy_device_free() before the "if" to always release it correctly.
Indeed, either phy_attach_direct() failed and we don't want to keep a
reference to the phydev or it succeeded and a reference has been taken
internally.

Pull s390 fixes from Heiko Carstens:

 - With CONFIG_VMAP_STACK enabled it is not possible to load the s390
   specific diag288_wdt watchdog module. The reason is that a pointer to
   a string is passed to an inline assembly; this string however is
   located on the stack, while the instruction within the inline
   assembly expects a physicial address. Fix this by copying the string
   to a kmalloc'ed buffer.

 - The diag288_wdt watchdog module does not indicate that it accesses
   memory from an inline assembly, which it does. Add "memory" to the
   clobber list to prevent the compiler from optimizing code incorrectly
   away.

 - Pass size of the uncompressed kernel image to __decompress() call.
   Otherwise the kernel image decompressor may corrupt/overwrite an
   initrd. This was reported to happen on s390 after commit 2aa14b1a

Fix mtk_eth_soc sgmii configuration.

This has been tested on a MT7986 with a Maxlinear GPY211C phy
permanently attached to the second SoC mac.

Currently there is no IRQ handling (even the SGMII supports it).
Enable polling to support SFP ports.

The logic of the duplex bit is inverted.  Setting it means half
duplex, not full duplex.

Fix and rename macro to avoid confusion.

The code expect the PHY to be in power down which is only true after reset.
Allow changes of the SGMII parameters more than once.

Only power down when reconfiguring to avoid bouncing the link when there's
no reason to - based on code from Russell King.

There are cases when the SGMII_PHYA_PWD register contains 0x9 which
prevents SGMII from working. The SGMII still shows link but no traffic
can flow. Writing 0x0 to the PHYA_PWD register fix the issue. 0x0 was
taken from a good working state of the SGMII interface.

The first patch is by Ziyang Xuan and removes a errant WARN_ON_ONCE()
in the CAN J1939 protocol.

The next 3 patches are by Oliver Hartkopp. The first 2 target the CAN
ISO-TP protocol and fix the state machine with respect to signals and
a regression found by the syzbot.

The last patch is by me an missing assignment during the ethtool ring
configuration callback.

We very rarely hear from Hideaki Yoshifuji and the IPv4/IPv6
entry covers a lot of code. Asking people to CC someone who
rarely responds feels wrong.

Note that Hideaki Yoshifuji already has an entry in CREDITS
for IPv6 so not adding another one.
