The ice_debug_cq function is called to print debug data for a control queue
descriptor in multiple places. This includes both before we send a message
on a transmit queue, after the writeback completion of a message on the
transmit queue, and when we receive a message on a receive queue.
This function does not include data about *which* control queue the message
is on, nor whether it was what we sent to the queue or what we received
from the queue.
Modify ice_debug_cq to take two extra parameters, a pointer to the control
queue and a boolean indicating if this was a response or a command. Improve
the debug messages by replacing "CQ CMD" with a string indicating which
specific control queue (based on cq->qtype) and whether this was a command
sent by the PF or a response from the queue.
This helps make the log output easier to understand and consume when
debugging.

The ice_sq_done function is used to check the control queue head register
and determine whether or not the control queue processing is done. This
function is called in a loop checking against jiffies for a specified
timeout.
The pattern of reading a register in a loop until a condition is true or a
timeout is reached is a relatively common pattern. In fact, the kernel
provides a read_poll_timeout function implementing this behavior in
<linux/iopoll.h>
Use of read_poll_timeout is preferred over directly coding these loops.
However, using it in the ice driver is a bit more difficult because of the
rd32 wrapper. Implement a rd32_poll_timeout wrapper based on
read_poll_timeout.
Refactor ice_sq_done to use rd32_poll_timeout, replacing the loop calling
ice_sq_done in ice_sq_send_cmd. This simplifies the logic down to a single
ice_sq_done() call.
The implementation of rd32_poll_timeout uses microseconds for its timeout
value, so update the CQ timeout macros used to be specified in microseconds
units as well instead of using HZ for jiffies.

BIT() is unsigned long but ->pu.flg_msk and ->pu.flg_val are u64 type.
On 32 bit systems, unsigned long is a u32 and the mismatch between u32

When working on multi-buffer packet on arch that has PAGE_SIZE >= 8192,
truesize is calculated and stored in xdp_buff::frame_sz per each
processed Rx buffer. This means that frame_sz will contain the truesize
based on last received buffer, but commit 1dc1a7e7f410 ("ice:
Centrallize Rx buffer recycling") assumed this value will be constant
for each buffer, which breaks the page recycling scheme and mess up the
way we update the page::page_offset.
To fix this, let us work on constant truesize when PAGE_SIZE >= 8192
instead of basing this on size of a packet read from Rx descriptor. This
way we can simplify the code and avoid calculating truesize per each
received frame and on top of that when using
xdp_update_skb_shared_info(), current formula for truesize update will
be valid.
This means ice_rx_frame_truesize() can be removed altogether.
Furthermore, first call to it within ice_clean_rx_irq() for 4k PAGE_SIZE
was redundant as xdp_buff::frame_sz is initialized via xdp_init_buff()
in ice_vsi_cfg_rxq(). This should have been removed at the point where
xdp_buff struct started to be a member of ice_rx_ring and it was no
longer a stack based variable.
There are two fixes tags as my understanding is that the first one
exposed us to broken truesize and page_offset handling and then second
introduced broken skb_shared_info update in ice_{construct,build}_skb().

Architectures that have PAGE_SIZE >= 8192 such as arm64 should act the
same as x86 currently, meaning reuse of a page should only take place
when no one else is busy with it.
Do two things independently of underlying PAGE_SIZE:
- store the page count under ice_rx_buf::pgcnt
- then act upon its value vs ice_rx_buf::pagecnt_bias when making the
decision regarding page reuse

Add support for offloading cls U32 filters. Only "skbedit queue_mapping"
and "drop" actions are supported. Also, only "ip" and "802_3" tc
protocols are allowed. The PF must advertise the VIRTCHNL_VF_OFFLOAD_TC_U32
capability flag.
Since the filters will be enabled via the FD stage at the PF, a new type
of FDIR filters is added and the existing list and state machine are used.
The new filters can be used to configure flow directors based on raw
(binary) pattern in the rx packet.
Examples:
0. # tc qdisc add dev enp175s0v0 ingress
1. Redirect UDP from src IP 192.168.2.1 to queue 12:
# tc filter add dev <dev> protocol ip ingress u32 \
match u32 0x45000000 0xff000000 at 0 \
match u32 0x00110000 0x00ff0000 at 8 \
match u32 0xC0A80201 0xffffffff at 12 \
match u32 0x00000000 0x00000000 at 24 \
action skbedit queue_mapping 12 skip_sw
2. Drop all ICMP:
# tc filter add dev <dev> protocol ip ingress u32 \
match u32 0x45000000 0xff000000 at 0 \
match u32 0x00010000 0x00ff0000 at 8 \
match u32 0x00000000 0x00000000 at 24 \
action drop skip_sw
3. Redirect ICMP traffic from MAC 3c:fd:fe:a5:47:e0 to queue 7
(note proto: 802_3):
# tc filter add dev <dev> protocol 802_3 ingress u32 \
match u32 0x00003CFD 0x0000ffff at 4 \
match u32 0xFEA547E0 0xffffffff at 8 \
match u32 0x08004500 0xffffff00 at 12 \
match u32 0x00000001 0x000000ff at 20 \
match u32 0x0000 0x0000 at 40 \
action skbedit queue_mapping 7 skip_sw
Notes on matches:
1 - All intermediate fields that are needed to parse the correct PTYPE
must be provided (in e.g. 3: Ethernet Type 0x0800 in MAC, IP version
and IP length: 0x45 and protocol: 0x01 (ICMP)).
2 - The last match must provide an offset that guarantees all required
headers are accounted for, even if the last header is not matched.
For example, in #2, the last match is 4 bytes at offset 24 starting
from IP header, so the total is 14 (MAC) + 24 + 4 = 42, which is the
sum of MAC+IP+ICMP headers.

marvell/otx2 and mvpp2 do not support setting different
keys for different RSS contexts. Contexts have separate
indirection tables but key is shared with all other contexts.
This is likely fine, indirection table is the most important
piece.
Don't report the key-related parameters from such drivers.
This prevents driver-errors, e.g. otx2 always writes
the main key, even when user asks to change per-context key.
The second reason is that without this change tracking
the keys by the core gets complicated. Even if the driver
correctly reject setting key with rss_context != 0,
change of the main key would have to be reflected in
the XArray for all additional contexts.
Since the additional contexts don't have their own keys
not including the attributes (in Netlink speak) seems
intuitive. ethtool CLI seems to deal with it just fine.
Having to set the flag in majority of the drivers is
a bit tedious but not reporting the key is a safer
default.

To workaround this, let us simply not wait for a disabled state as later

One could argue that bailing out early in ice_xsk_wakeup() would be
sufficient but given the fact that we produce Tx descriptors on behalf
of NAPI that is triggered for Rx traffic, the latter is also needed.
Bringing link up is an asynchronous event executed within
ice_service_task so even though interface has been brought up there is
still a time frame where link is not yet ok.
Without this patch, when AF_XDP ZC Tx is used simultaneously with stack
Tx, Tx timeouts occur after going through link flap (admin brings
interface down then up again). HW seem to be unable to transmit
descriptor to the wire after HW tail register bump which in turn causes
bit __QUEUE_STATE_STACK_XOFF to be set forever as
netdev_tx_completed_queue() sees no cleaned bytes on the input.

Pull driver core updates from Greg KH:
"Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases
to get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions.
It's not all that useful for a "write a whole driver in rust" type
of thing, but the firmware bindings do help out the phy rust
drivers, and the driver core bindings give a solid base on which
others can start their work.
There is still a long way to go here before we have a multitude of
rust drivers being added, but it's a great first step.
- driver core const api changes.
This reached across all bus types, and there are some fix-ups for
some not-common bus types that linux-next and 0-day testing shook
out.
This work is being done to help make the rust bindings more safe,
as well as the C code, moving toward the end-goal of allowing us to
put driver structures into read-only memory. We aren't there yet,
but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no

When ice driver reads recipes from firmware information about
need_pass_l2 and allow_pass_l2 flags is not stored correctly.
Those flags are stored as one bit each in ice_sw_recipe structure.
Because of that, the result of checking a flag has to be casted to bool.
Note that the need_pass_l2 flag currently works correctly, because
it's stored in the first bit.

Pull networking updates from Jakub Kicinski:
"Not much excitement - a handful of large patchsets (devmem among them)
did not make it in time.
Core & protocols:
- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT
- Use flex array for netdevice priv area, ensure its cache alignment
- Add a sysctl knob to allow user to specify a default rto_min at
socket init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful
- Support scheduling transmission of packets based on CLOCK_TAI
- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
off using cpusets
- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address
- Allow configuration of multipath hash seed, to both allow
synchronizing hashing of two routers, and preventing partial
accidental sync
- Improve TCP compliance with RFC 9293 for simultaneous connect()
- Support sending NAT keepalives in IPsec ESP in UDP states.
Userspace IKE daemon had to do this before, but the kernel can
better keep track of it
- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled
- Introduce IPPROTO_SMC for selecting SMC when socket is created
- Allow UDP GSO transmit from devices with no checksum offload
- openvswitch: add packet sampling via psample, separating the
sampled traffic from "upcall" packets sent to user space for
forwarding
- nf_tables: shrink memory consumption for transaction objects
Things we sprinkled into general kernel code:
- Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
QCA6390) [ Already merged separately - Linus ]
- Add IRQ information in sysfs for auxiliary bus
- Introduce guard definition for local_lock
- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures
BPF:
- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered
- Add new kfuncs for a generic, open-coded bits iterator
- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head
- Support resilient split BTF which cuts down on duplication and
makes BTF as compact as possible WRT BTF from modules
- Add support for dumping kfunc prototypes from BTF which enables
both detecting as well as dumping compilable prototypes for kfuncs
- riscv64 BPF JIT improvements in particular to add 12-argument
support for BPF trampolines and to utilize bpf_prog_pack for the
latter
- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs
Driver API:
- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose

In prevision to add new UAPI for hwtstamp we will be limited to the struct
ethtool_ts_info that is currently passed in fixed binary format through the
ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code
already started operating on an extensible kernel variant of that
structure, similar in concept to struct kernel_hwtstamp_config vs struct
hwtstamp_config.
Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here
we introduce the kernel-only structure in include/linux/ethtool.h.
The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

ice: Switch API optimizations
Marcin Szycik says:
Optimize the process of creating a recipe in the switch block by removing
duplicate switch ID words and changing how result indexes are fitted into
recipes. In many cases this can decrease the number of recipes required to
add a certain set of rules, potentially allowing a more varied set of rules
to be created. Total rule count will also increase, since less words will
be left unused/wasted. There are only 64 rules available in total, so every
one counts.
After this modification, many fields and some structs became unused or were
simplified, resulting in overall simpler implementation.

Add support for driver-specific devlink local_forwarding param.
Supported values are "enabled", "disabled" and "prioritized".
Default configuration is set to "enabled".
Add documentation in networking/devlink/ice.rst.
In previous generations of Intel NICs the transmit scheduler was only
limited by PCIe bandwidth when scheduling/assigning hairpin-bandwidth
between VFs. Changes to E810 HW design introduced scheduler limitation,
so that available hairpin-bandwidth is bound to external port speed.
In order to address this limitation and enable NFV services such as
"service chaining" a knob to adjust the scheduler config was created.
Driver can send a configuration message to the FW over admin queue and
internal FW logic will reconfigure HW to prioritize and add more BW to
VF to VF traffic. An end result, for example, 10G port will no longer
limit hairpin-bandwidth to 10G and much higher speeds can be achieved.
Devlink local_forwarding param set to "prioritized" enables higher
hairpin-bandwitdh on related PFs. Configuration is applicable only to
8x10G and 4x25G cards.
Changing local_forwarding configuration will trigger CORER reset in
order to take effect.
Example command to change current value:
devlink dev param set pci/0000:b2:00.3 name local_forwarding \
value prioritized \
cmode runtime

Track the number of rules and recipes added to switch. Add a tracepoint to
ice_aq_sw_rules(), which shows both rule and recipe count. This information
can be helpful when designing a set of rules to program to the hardware, as
it shows where the practical limit is. Actual limits are known (64 recipes,
32k rules), but it's hard to translate these values to how many rules the
*user* can actually create, because of extra metadata being implicitly
added, and recipe/rule chaining. Chaining combines several recipes/rules to
create a larger recipe/rule, so one large rule added by the user might
actually consume multiple rules from hardware perspective.
Rule counter is simply incremented/decremented in ice_aq_sw_rules(), since
all rules are added or removed via it.
Counting recipes is harder, as recipes can't be removed (only overwritten).
Recipes added via ice_aq_add_recipe() could end up being unused, when
there is an error in later stages of rule creation. Instead, track the
allocation and freeing of recipes, which should reflect the actual usage of
recipes (if something fails after recipe(s) were created, caller should
free them). Also, a number of recipes are loaded from NVM by default -
initialize the recipe counter with the number of these recipes on switch
initialization.
Example configuration:
cd /sys/kernel/tracing
echo function > current_tracer
echo ice_aq_sw_rules > set_ftrace_filter
echo ice_aq_sw_rules > set_event
echo 1 > tracing_on
cat trace
Example output:

Currently when creating switch recipes, switch ID is always added as the
first word in every recipe. There are only 5 words in a recipe, so one
word is always wasted. This is also true for the last recipe, which stores
result indexes (in case of chain recipes). Therefore the maximum usable
length of a chain recipe is 4 * 4 = 16 words. 4 words in a recipe, 4
recipes that can be chained (using a 5th one for result indexes).
Current max size chained recipe:
0: smmmm
1: smmmm
2: smmmm
3: smmmm
4: srrrr
Where:
s - switch ID
m - regular match (e.g. ipv4 src addr, udp dst port, etc.)
r - result index
Switch ID does not actually need to be present in every recipe, only in one
of them (in case of chained recipe). This frees up to 8 extra words:
3 from recipes in the middle (because first recipe still needs to have
switch ID), and 5 from one extra recipe (because now the last recipe also
does not have switch ID, so it can chain 1 more recipe).
Max size chained recipe after changes:
0: smmmm
1: Mmmmm
2: Mmmmm
3: Mmmmm
4: MMMMM
5: Rrrrr
Extra usable words available after this change are highlighted with capital
letters.
Changing how switch ID is added is not straightforward, because it's not a
regular lookup. Its FV index and mask can't be determined based on protocol
+ offset pair read from package and instead need to be added manually.
Additionally, change how result indexes are added. Currently they are
always inserted in a new recipe at the end. Example for 13 words, (with
above optimization, switch ID being one of the words):
0: smmmm
1: mmmmm
2: mmmxx
3: rrrxx
Where:
x - unused word
In this and some other cases, the result indexes can be moved just after
last matches because there are unused words, saving one recipe. Example
for 13 words after both optimizations:
0: smmmm
1: mmmmm
2: mmmrr
Note how one less result index is needed in this case, because the last
recipe does not need to "link" to itself.
There are cases when adding an additional recipe for result indexes cannot
be avoided. In that cases result indexes are all put in the last recipe.
Example for 14 words after both optimizations:
0: smmmm
1: mmmmm
2: mmmmx
3: rrrxx
With these two changes, recipes/rules are more space efficient, allowing
more to be created in total.

Remove root_buf from recipe struct. Its only usage was in ice_find_recp(),
where if recipe had an inverse action, it was skipped, but actually the
driver never adds inverse actions, so effectively it was pointless.
Without root_buf, the recipe data element in ice_add_sw_recipe() does
not need to be persistent and can also be automatically deallocated with
__free, which nicely simplifies unroll.

Remove unnecessary size checks when copying bitmaps in ice_add_sw_recipe()
and replace them with compile time assert. Check if the bitmaps are equal
size, as they are copied both ways.

The content of the first read recipe is used as a template when adding a
recipe. It isn't needed - only prune index is directly set from there. Set
it in the code instead. Also, now there's no need to set rid and lookup
indexes to 0, as the whole recipe buffer is initialized to 0.

Remove field_off as it's never used.
Remove done bitmap, as its value is only checked and never assigned.
Reusing sub-recipes while creating new root recipes is currently not
supported in the driver.
