In switchdev mode VF VLAN caps will not be set there is no need
to have specific VLAN ops for representor that only returns not
supported error.
As VLAN configuration commands will be blocked, the VF driver
can't disable VLAN stripping at initialization. It leads to the
situation when VLAN stripping on VF VSI is on, but in kernel it
is off. To prevent this, disable VLAN stripping in VSI
initialization. It doesn't break other usecases, because it is set
according to kernel settings.

In switchdev mode any VLAN manipulation from VF side isn't allowed.
In order to prevent parsing VLAN commands don't set VF VLAN caps.
This will result in removing VLAN specific opcodes from allowlist.
If VF send any VLAN specific opcode PF driver will answer with not
supported error.
With this approach VF driver know that VLAN caps aren't supported so it
shouldn't send VLAN specific opcodes. Thanks to that, some ugly errors
will not show up in dmesg (ex. on creating VFs in switchdev mode
there are errors about not supported VLAN insertion and stripping)
Move setting VLAN caps to separate function, including
switchdev mode specific code.

When the promiscuous mode is enabled on a VF, the IXGBE_VMOLR_VPE
bit (VLAN Promiscuous Enable) is set. This means that the VF will
receive packets whose VLAN is not the same than the VLAN of the VF.
For instance, in this situation:
┌────────┐ ┌────────┐ ┌────────┐
│ │ │ │ │ │
│ │ │ │ │ │
│ VF0├────┤VF1 VF2├────┤VF3 │
│ │ │ │ │ │
└────────┘ └────────┘ └────────┘
VM1 VM2 VM3
vf 0: vlan 1000
vf 1: vlan 1000
vf 2: vlan 1001
vf 3: vlan 1001
If we tcpdump on VF3, we see all the packets, even those transmitted
on vlan 1000.
This behavior prevents to bridge VF1 and VF2 in VM2, because it will
create a loop: packets transmitted on VF1 will be received by VF2 and
vice-versa, and bridged again through the software bridge.
This patch remove the activation of VLAN Promiscuous when a VF enables
the promiscuous mode. However, the IXGBE_VMOLR_UPE bit (Unicast
Promiscuous) is kept, so that a VF receives all packets that has the
same VLAN, whatever the destination MAC address.

After a VF requested to remove the promiscuous flag on an interface, the
broadcast packets are not received anymore. This breaks some protocols
like ARP.
In ixgbe_update_vf_xcast_mode(), we should keep the IXGBE_VMOLR_BAM
bit (Broadcast Accept) on promiscuous removal.
This flag is already set by default in ixgbe_set_vmolr() on VF reset.

VFs by default are able to see all tagged traffic regardless of trust
and VLAN filters configured.
Add new private flag vf-vlan-pruning that allows changing of default
VF behavior for tagged traffic. When the flag is turned on
untrusted VF will only be able to receive untagged traffic
or traffic with VLAN tags it has created interfaces for
The flag is off by default and can only be changed if
there are no VFs spawned on the PF. This flag will only be effective
when no PVID is set on VF and VF is not trusted.
Add new function that computes the correct VLAN ID for VF VLAN filters
based on trust, PVID, vf-vlan-prune-disable flag and current VLAN ID.
Testing Hints:
Test 1: vf-vlan-pruning == off
==============================
1. Set the private flag
> ethtool --set-priv-flag eth0 vf-vlan-pruning off (default setting)
2. Use scapy to send any VLAN tagged traffic and make sure the VF
receives all VLAN tagged traffic that matches its destination MAC
filters (unicast, multicast, and broadcast).
Test 2: vf-vlan-pruning == on
==============================
1. Set the private flag
> ethtool --set-priv-flag eth0 vf-vlan-pruning on
2. Use scapy to send any VLAN tagged traffic and make sure the VF does
not receive any VLAN tagged traffic that matches its destination MAC
filters (unicast, multicast, and broadcast).
3. Add a VLAN filter on the VF netdev
> ip link add link eth0v0 name vlan10 type vlan id 10
4. Bring the VLAN netdev up
> ip link set vlan10 up
4. Use scapy to send traffic with VLAN 10, VLAN 11 (anything not VLAN
10), and untagged traffic. Make sure the VF only receives VLAN 10
and untagged traffic when the link partner is sending.
Test 3: vf-vlan-pruning == off && VF is in a port VLAN
==============================
1. Set the private flag
> ethtool --set-priv-flag eth0 vf-vlan-pruning off (default setting)
2. Create a VF
> echo 1 > sriov_numvfs
3. Put the VF in a port VLAN
> ip link set eth0 vf 0 vlan 10
4. Use scapy to send traffic with VLAN 10 and VLAN 11 (anything not VLAN
10) and make sure the VF only receives untagged traffic when the link
partner is sending VLAN 10 tagged traffic as the VLAN tag is expected
to be stripped by HW for port VLANs and not visible to the VF.
Test 4: Change vf-vlan-pruning while VFs are created
==============================
echo 0 > sriov_numvfs
ethtool --set-priv-flag eth0 vf-vlan-pruning off
echo 1 > sriov_numvfs
ethtool --set-priv-flag eth0 vf-vlan-pruning on (expect failure)

Global `-Warray-bounds` enablement revealed some problems, one of
which is the way we define and use AQC rules messages.
In fact, they have a shared header, followed by the actual message,
which can be of one of several different formats. So it is
straightforward enough to define that header as a separate struct
and then embed it into message structures as needed, but currently
all the formats reside in one union coupled with the header. Then,
the code allocates only the memory needed for a particular message
format, leaving the union potentially incomplete.
There are no actual reads or writes beyond the end of an allocated
chunk, but at the same time, the whole implementation is fragile and
backed by an equilibrium rather than strong type and memory checks.
Define the structures the other way around: one for the common
header and the rest for the actual formats with the header embedded.
There are no places where several union members would be used at the
same time anyway. This allows to use proper struct_size() and let
the compiler know what is going to be done.
Finally, unsilence `-Warray-bounds` back for ice_switch.c.
Other little things worth mentioning:
* &ice_sw_rule_vsi_list_query is not used anywhere, remove it. It's
weird anyway to talk to hardware with purely kernel types
(bitmaps);
* expand the ICE_SW_RULE_*_SIZE() macros to pass a structure
variable name to struct_size() to let it do strict typechecking;
* rename ice_sw_rule_lkup_rx_tx::hdr to ::hdr_data to keep ::hdr
for the header structure to have the same name for it constistenly
everywhere;
* drop the duplicate of %ICE_SW_RULE_RX_TX_NO_HDR_SIZE residing in
ice_switch.h.

Adaptive-rx and Adaptive-tx are interrupt moderation settings
that can be enabled/disabled using ethtool:
ethtool -C ethX adaptive-rx on/off adaptive-tx on/off
Unfortunately those settings are getting cleared after
changing number of queues, or in ethtool world 'channels':
ethtool -L ethX rx 1 tx 1
Clearing was happening due to introduction of bit fields
in ice_ring_container struct. This way only itr_setting
bits were rebuilt during ice_vsi_rebuild_set_coalesce().
Introduce an anonymous struct of bitfields and create a
union to refer to them as a single variable.

The hardware statistics counters are not cleared during resets so the
drivers first access is to initialize the baseline and then subsequent
reads are for reporting the counters. The statistics counters are read
during the watchdog subtask when the interface is up. If the baseline
is not initialized before the interface is up, then there can be a brief
window in which some traffic can be transmitted/received before the
initial baseline reading takes place.
Directly initialize ethtool statistics in driver open so the baseline will
be initialized when the interface is up, and any dropped packets
incremented before the interface is up won't be reported.

100GbE Intel Wired LAN Driver Updates 2022-05-06
Marcin Szycik says:
This patchset adds support for systemd defined naming scheme for port
representors, as well as re-enables displaying PCI bus-info in ethtool.
bus-info information has previously been removed from ethtool for port
representors, as a workaround for a bug in lshw tool, where the tool would
sometimes display wrong descriptions for port representors/PF. Now the bug
has been fixed in lshw tool [1].
Removing the workaround can be considered a regression (user might be
running an older, unpatched version of lshw) (see [2] for discussion).
However, calling SET_NETDEV_DEV also produces the same effect as removing
the workaround, i.e. lshw is able to access PCI bus-info (this time not
via ethtool, but in some other way) and the bug can occur.
Adding SET_NETDEV_DEV is important, as it greatly improves netdev naming -
- port representors are named based on PF name. Currently port representors
are named "ethX", which might be confusing, especially when spawning VFs on
multiple PFs. Furthermore, it's currently harder to determine to which PF
does a particular port representor belong, as bus-info is not shown in
ethtool.
Consider the following three cases:
Case 1: current code - driver workaround in place, no SET_NETDEV_DEV,
lshw with or without fix. Port representors are not displayed because they
don't have bus-info (the workaround), PFs are labelled correctly:
$ sudo ./lshw -c net -businfo
Bus info Device Class Description
========================================================
pci@0000:02:00.0 ens6f0 network Ethernet Controller E810-XXV for SFP <-- PF
pci@0000:02:00.1 ens6f1 network Ethernet Controller E810-XXV for SFP
pci@0000:02:01.0 ens6f0v0 network Ethernet Adaptive Virtual Function <-- VF
pci@0000:02:01.1 ens6f0v1 network Ethernet Adaptive Virtual Function
...
Case 2: driver workaround in place, SET_NETDEV_DEV, no lshw fix. Port
representors have predictable names. lshw is able to get bus-info because
of SET_NETDEV_DEV and netdevs CAN be mislabelled:
$ sudo ./lshw -c net -businfo
Bus info Device Class Description
=============================================================
pci@0000:02:00.0 ens6f0npf0vf60 network Ethernet Controller E810-XXV for SFP <-- mislabeled port representor
pci@0000:02:00.1 ens6f1 network Ethernet Controller E810-XXV for SFP
pci@0000:02:01.0 ens6f0v0 network Ethernet Adaptive Virtual Function
pci@0000:02:01.1 ens6f0v1 network Ethernet Adaptive Virtual Function
...
pci@0000:02:00.0 ens6f0npf0vf26 network Ethernet interface
pci@0000:02:00.0 ens6f0 network Ethernet interface <-- mislabeled PF
pci@0000:02:00.0 ens6f0npf0vf81 network Ethernet interface
...
$ sudo ethtool -i ens6f0npf0vf60
driver: ice
...
bus-info:
...
Output of lshw would be the same with workaround removed; it does not
change the fact that lshw labels netdevs incorrectly, while at the same
time it prevents ethtool from displaying potentially useful data
(bus-info).
Case 3: workaround removed, SET_NETDEV_DEV, lshw fix:
$ sudo ./lshw -c net -businfo
Bus info Device Class Description
=============================================================
pci@0000:02:00.0 ens6f0npf0vf73 network Ethernet Controller E810-XXV for SFP
pci@0000:02:00.1 ens6f1 network Ethernet Controller E810-XXV for SFP
pci@0000:02:01.0 ens6f0v0 network Ethernet Adaptive Virtual Function
pci@0000:02:01.1 ens6f0v1 network Ethernet Adaptive Virtual Function
...
pci@0000:02:00.0 ens6f0npf0vf5 network Ethernet Controller E810-XXV for SFP
pci@0000:02:00.0 ens6f0 network Ethernet Controller E810-XXV for SFP
pci@0000:02:00.0 ens6f0npf0vf60 network Ethernet Controller E810-XXV for SFP
...
$ sudo ethtool -i ens6f0npf0vf73
driver: ice
...
bus-info: 0000:02:00.0
...
In this case poort representors have predictable names, netdevs are not
mislabelled in lshw, and bus-info is shown in ethtool.

Read stale PTP Tx timestamps from PHY on cleanup.
After running out of Tx timestamps request handlers, hardware (HW) stops
reporting finished requests. Function ice_ptp_tx_tstamp_cleanup() used
to only clean up stale handlers in driver and was leaving the hardware
registers not read. Not reading stale PTP Tx timestamps prevents next
interrupts from arriving and makes timestamping unusable.

The iAVF driver uses 3 virtchnl op codes to communicate with the PF
regarding the VF Tx queues:
* VIRTCHNL_OP_CONFIG_VSI_QUEUES configures the hardware and firmware
logic for the Tx queues
* VIRTCHNL_OP_ENABLE_QUEUES configures the queue interrupts
* VIRTCHNL_OP_DISABLE_QUEUES disables the queue interrupts and Tx rings.
There is a bug in the iAVF driver due to the race condition between VF
reset request and shutdown being executed in parallel. This leads to a
break in logic and VIRTCHNL_OP_DISABLE_QUEUES is not being sent.
If this occurs, the PF driver never cleans up the Tx queues. This results
in leaving behind stale Tx queue settings in the hardware and firmware.
The most obvious outcome is that upon the next
VIRTCHNL_OP_CONFIG_VSI_QUEUES, the PF will fail to program the Tx
scheduler node due to a lack of space.
We need to protect ICE driver against such situation.
To fix this, make sure we clear existing stale settings out when
handling VIRTCHNL_OP_CONFIG_VSI_QUEUES. This ensures we remove the
previous settings.
Calling ice_vf_vsi_dis_single_txq should be safe as it will do nothing if
the queue is not configured. The function already handles the case when the
Tx queue is not currently configured and exits with a 0 return in that
case.

Function ice_plug_aux_dev() assigns pf->adev field too early prior
aux device initialization and on other side ice_unplug_aux_dev()
starts aux device deinit and at the end assigns NULL to pf->adev.
This is wrong because pf->adev should always be non-NULL only when
aux device is fully initialized and ready. This wrong order causes
a crash when ice_send_event_to_aux() call occurs because that function
depends on non-NULL value of pf->adev and does not assume that
aux device is half-initialized or half-destroyed.
After order correction the race window is tiny but it is still there,
as Leon mentioned and manipulation with pf->adev needs to be protected
by mutex.
Fix (un-)plugging functions so pf->adev field is set after aux device
init and prior aux device destroy and protect pf->adev assignment by
new mutex. This mutex is also held during ice_send_event_to_aux()
call to ensure that aux device is valid during that call.
Note that device lock used ice_send_event_to_aux() needs to be kept
to avoid race with aux drv unload.
Reproducer:

echo "#### Cycle: $cycle"

ip link set bond0 mtu 9000
ethtool -L ens7f0 combined 1
ip link del bond0
ip link set ens7f0 mtu 1500
sleep 1
let cycle++
done
In short when the device is added/removed to/from bond the aux device
is unplugged/plugged. When MTU of the device is changed an event is
sent to aux device asynchronously. This can race with (un)plugging
operation and because pf->adev is set too early (plug) or too late
(unplug) the function ice_send_event_to_aux() can touch uninitialized
or destroyed fields. In the case of crash below pf->adev->dev.mutex.

This reverts commit bfaaba99e680bf82bf2cbf69866c3f37434ff766.
Commit bfaaba99e680 ("ice: Hide bus-info in ethtool for PRs in switchdev
mode") was a workaround for lshw tool displaying incorrect
descriptions for port representors and PF in switchdev mode. Now the issue
has been fixed in the lshw tool itself [1].
Removing the workaround can be considered a regression, as the user might
be running older, unpatched lshw version. However, another important change
(ice: link representors to PCI device, which improves port representor
netdev naming with SET_NETDEV_DEV) also causes the same "regression" as
removing the workaround, i.e. unpatched lshw is able to access bus-info
information (this time not via ethtool) and the bug can occur. Therefore,
the workaround no longer prevents the bug and can be removed.

The ice_get_vf_vsi function can return NULL in some cases, such as if
handling messages during a reset where the VSI is being removed and
recreated.
Several places throughout the driver do not bother to check whether this
VSI pointer is valid. Static analysis tools maybe report issues because
they detect paths where a potentially NULL pointer could be dereferenced.
Fix this by checking the return value of ice_get_vf_vsi everywhere.

Switch id should be the same for each netdevice on a driver.
The id must be unique between devices on the same system, but
does not need to be unique between devices on different systems.
The switch id is used to locate ports on a switch and to know if
aggregated ports belong to the same switch.
To meet this requirements, use pci_get_dsn as switch id value, as
this is unique value for each devices on the same system.
Implementing switch id is needed by automatic tools for kubernetes.
Set switch id by setting devlink port attribiutes and calling
devlink_port_attrs_set while creating pf (for uplink) and vf
(for representator) devlink port.
