ice: refactor mailbox overflow detection
Jake Keller says:
The primary motivation of this series is to cleanup and refactor the mailbox
overflow detection logic such that it will work with Scalable IOV. In
addition a few other minor cleanups are done while I was working on the
code in the area.
First, the mailbox overflow functions in ice_vf_mbx.c are refactored to
store the data per-VF as an embedded structure in struct ice_vf, rather than
stored separately as a fixed-size array which only works with Single Root
IOV. This reduces the overall memory footprint when only a handful of VFs
are used.
The overflow detection functions are also cleaned up to reduce the need for
multiple separate calls to determine when to report a VF as potentially
malicious.
Finally, the ice_is_malicious_vf function is cleaned up and moved into
ice_virtchnl.c since it is not Single Root IOV specific, and thus does not
belong in ice_sriov.c
I could probably have done this in fewer patches, but I split pieces out to
hopefully aid in reviewing the overall sequence of changes. This does cause
some additional thrash as it results in intermediate versions of the
refactor, but I think its worth it for making each step easier to
understand.

i40e: support XDP multi-buffer
Tirthendu Sarkar says:
This patchset adds multi-buffer support for XDP. Tx side already has
support for multi-buffer. This patchset focuses on Rx side. The last
patch contains actual multi-buffer changes while the previous ones are
preparatory patches.
On receiving the first buffer of a packet, xdp_buff is built and its
subsequent buffers are added to it as frags. While 'next_to_clean' keeps
pointing to the first descriptor, the newly introduced 'next_to_process'
keeps track of every descriptor for the packet.
On receiving EOP buffer the XDP program is called and appropriate action
is taken (building skb for XDP_PASS, reusing page for XDP_DROP, adjusting
page offsets for XDP_{REDIRECT,TX}).
The patchset also streamlines page offset adjustments for buffer reuse
to make it easier to post process the rx_buffers after running XDP prog.
With this patchset there does not seem to be any performance degradation
for XDP_PASS and some improvement (~1% for XDP_TX, ~5% for XDP_DROP) when
measured using xdp_rxq_info program from samples/bpf/ for 64B packets.

net: virtio_net: implement exact header length guest feature
Virtio spec introduced a feature VIRTIO_NET_F_GUEST_HDRLEN which when
set implicates that device benefits from knowing the exact size
of the header. For compatibility, to signal to the device that
the header is reliable driver also needs to set this feature.
Without this feature set by driver, device has to figure
out the header size itself.
Quoting the original virtio spec:
"hdr_len is a hint to the device as to how much of the header needs to
be kept to copy into each packet"
"a hint" might not be clear for the reader what does it mean, if it is
"maybe like that" of "exactly like that". This feature just makes it
crystal clear and let the device count on the hdr_len being filled up
by the exact length of header.
Also note the spec already has following note about hdr_len:
"Due to various bugs in implementations, this field is not useful
as a guarantee of the transport header size."
Without this feature the device needs to parse the header in core
data path handling. Accurate information helps the device to eliminate
such header parsing and directly use the hardware accelerators
for GSO operation.
virtio_net_hdr_from_skb() fills up hdr_len to skb_headlen(skb).
The driver already complies to fill the correct value. Introduce the
feature and advertise it.
Note that virtio spec also includes following note for device
implementation:
"Caution should be taken by the implementation so as to prevent
a malicious driver from attacking the device by setting
an incorrect hdr_len."
There is a plan to support this feature in our emulated device.
A device of SolidRun offers this feature bit. They claim this feature
will save the device a few cycles for every GSO packet.

net: hsr: Don't log netdev_err message on unknown prp dst node
If no frames has been exchanged with a node for HSR_NODE_FORGET_TIME, the
node will be deleted from the node_db list. If a frame is sent to the node
after it is deleted, a netdev_err message for each slave interface is
produced. This should not happen with dan nodes because of supervision
frames, but can happen often with san nodes, which clutters the kernel
log. Since the hsr protocol does not support sans, this is only relevant
for the prp protocol.

net: phy: micrel: Add support for PTP_PF_PEROUT for lan8841
Lan8841 has 10 GPIOs and it has 2 events(EVENT_A and EVENT_B). It is
possible to assigned the 2 events to any of the GPIOs, but a GPIO can
have only 1 event at a time.
These events are used to generate periodic signals. It is possible to
configure the length, the start time and the period of the signal by
configuring the event.
Currently the SW uses only EVENT_A to generate the perout.
These events are generated by comparing the target time with the PHC
time. In case the PHC time is changed to a value bigger than the target
time + reload time, then it would generate only 1 event and then it
would stop because target time + reload time is small than PHC time.
Therefore it is required to change also the target time every time when
the PHC is changed. The same will apply also when the PHC time is
changed to a smaller value.

ice: call ice_is_malicious_vf() from ice_vc_process_vf_msg()
The main loop in __ice_clean_ctrlq first checks if a VF might be malicious
before calling ice_vc_process_vf_msg(). This results in duplicate code in
both functions to obtain a reference to the VF, and exports the
ice_is_malicious_vf() from ice_virtchnl.c unnecessarily.
Refactor ice_is_malicious_vf() to be a static function that takes a pointer
to the VF. Call this in ice_vc_process_vf_msg() just after we obtain a
reference to the VF by calling ice_get_vf_by_id.
Pass the mailbox data from the __ice_clean_ctrlq function into
ice_vc_process_vf_msg() instead of calling ice_is_malicious_vf().
This reduces the number of exported functions and avoids the need to obtain
the VF reference twice for every mailbox message.
Note that the state check for ICE_VF_STATE_DIS is kept in
ice_is_malicious_vf() and we call this before checking that state in
ice_vc_process_vf_msg. This is intentional, as we stop responding to VF
messages from a VF once we detect that it may be overflowing the mailbox.
This ensures that we continue to silently ignore the message as before
without responding via ice_vc_send_msg_to_vf().

Currently the PF tracks malicious VFs in a malvfs bitmap which is used by

used to ensure that we only report a VF as malicious once rather than
continuously spamming the event log.
This mechanism of storage for the malicious indication works well enough
for SR-IOV. However, it will not work with Scalable IOV. This is because
Scalable IOV VFs can be allocated dynamically and might change VF ID when
their underlying VSI changes.
To support this, the mailbox overflow logic will need to be refactored.
First, introduce a new ice_mbx_vf_info structure which will be used to
store data about a VF. Embed this structure in the struct ice_vf, and
ensure it gets initialized when a new VF is created.
For now this only stores the malicious indicator bit. Pass a pointer to the

conditions are kept the same.
The second patch extends the check for soft-state polling and control
by using this "have_a2" flag (which effectively augments the check to
include some level of SFF8472 compliance.)

net: sfp: only use soft polling if we have A2h access
The soft state bits are stored in the A2h memory space, and require
SFF-8472 compliance. This is what our have_a2 flag tells us, so use
this to indicate whether we should attempt to use the soft signals.

net: sfp: add A2h presence flag
The hwmon code wants to know when it is safe to access the A2h data
stored in a separate address. We indicate that this is present when
we have SFF-8472 compliance and the lack of an address-change
sequence.,
The same conditions are also true if we want to access other controls
and status in the A2h address. So let's make a flag to indicate whether
we can access it, instead of repeating the conditions throughout the
code.
For now, only convert the hwmon code.

Horatiu Vultur says:
====================
net: lan966x: Add support for IS1 VCAP
Provide the Ingress Stage 1 (IS1) VCAP (Versatile Content-Aware
Processor) support for the Lan966x platform.
The IS1 VCAP has 3 lookups and they are accessible with a TC chain id:
- chain 1000000: IS1 Lookup 0
- chain 1100000: IS1 Lookup 1
- chain 1200000: IS1 Lookup 2
The IS1 is capable of different actions like rewrite VLAN tags, change
priority of the frames, police the traffic, etc. These features will be
added at a later point.
The IS1 currently implements the action that allows setting the value
of a PAG (Policy Association Group) key field in the frame metadata and
this can be used for matching in an IS2 VCAP rule. In this way a rule in
IS0 VCAP can be linked to rules in the IS2 VCAP. The linking is exposed
by using the TC "goto chain" action with an offset from the IS2 chain ids.
For example "goto chain 8000001" will use a PAG value of 1 to chain to a
rule in IS2 lookup 0.
