The macros are preparation for adding module aliases en mass in a
separate commit.
Although it would be tempting to create aliases like cls-foo for name
cls_foo, this could not be used because modprobe utilities treat '-' and
'_' interchangeably.
In the end, the naming follows pattern of proto modules in linux/net.h.

Dynamically allocate BPIDs for LBK
In current driver 64 BPIDs are reserved for LBK interfaces.
These bpids are 1-to-1 mapped to LBK interface channel numbers.
In some usecases one LBK interface required more than one bpids
and in some case they may not require at all. These usescas
can't be address with the current implementation as it always
reserves only one bpid per LBK channel.
This patch addresses this issue by creating free bpid pool from

Now based on usecase LBK interface can request a bpid using (bp_enable()).

PCI device IDs of RVU device IDs are configurable and
RVU PF0's (ie AF's) are currently assumed as VFs that
identify loopback functionality ie LBKVFs. But in some
cases these VFs can be setup for different functionality.
Hence remove assumptions that AF's VFs are always LBK VFs
by renaming 'is_afvf' as 'is_lbkvf' explicitly and also
identify LBK VF using PCI dev ID. Similar change is done
for other VF types.

net: mdio-ipq4019: fix wrong default MDC rate
This was a long journey to arrive and discover this problem.
To not waste too much char, there is a race problem with PHY and driver
probe. This was observed with Aquantia PHY firmware loading.
With some hacks the race problem was workarounded but an interesting
thing was notice. It took more than a minute for the firmware to load
via MDIO.
This was strange as the same operation was done by UBoot in at max 5
second and the same data was loaded.
A similar problem was observed on a mtk board that also had an
Aquantia PHY where the load was very slow. It was notice that the cause
was the MDIO bus running at a very low speed and the firmware
was missing a property (present in mtk sdk) that set the right frequency
to the MDIO bus.
It was fun to find that THE VERY SAME PROBLEM is present on IPQ in a
different form. The MDIO apply internally a division to the feed clock
resulting in the bus running at 390KHz instead of 6.25Mhz.
Searching around the web for some documentation and some include and
analyzing the uboot codeflow resulted in the divider being set wrongly
at /256 instead of /16 as the value was actually never set.
Applying the value restore the original load time for the Aquantia PHY.
This series mainly handle this by adding support for the "clock-frequency"
property.
Changes v3:
- Add Reviewed-by tag
- Fix english grammar error in comment
- Drop DTS patch
Changes v2:
- Use DIV_ROUND_UP
- Introduce logic to chose a default value for 802.3 spec 2.5MHz
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The IPQ4019 MDIO internally divide the clock feed by AHB based on the
MDIO_MODE reg. On reset or power up, the default value for the
divider is 0xff that reflect the divider set to /256.
This makes the MDC run at a very low rate, that is, considering AHB is
always fixed to 100Mhz, a value of 390KHz.
This hasn't have been a problem as MDIO wasn't used for time sensitive
operation, it is now that on IPQ807x is usually mounted with PHY that
requires MDIO to load their firmware (example Aquantia PHY).
To handle this problem and permit to set the correct designed MDC
frequency for the SoC add support for the standard "clock-frequency"
property for the MDIO node.
The divider supports value from /1 to /256 and the common value are to
set it to /16 to reflect 6.25Mhz or to /8 on newer platform to reflect
12.5Mhz.
To scan if the requested rate is supported by the divider, loop with
each supported divider and stop when the requested rate match the final
rate with the current divider. An error is returned if the rate doesn't
match any value.
On MDIO reset, the divider is restored to the requested value to prevent
any kind of downclocking caused by the divider reverting to a default
value.
To follow 802.3 spec of 2.5MHz of default value, if divider is set at
/256 and "clock-frequency" is not set in DT, assume nobody set the
divider and try to find the closest MDC rate to 2.5MHz. (in the case of
AHB set to 100MHz, it's 1.5625MHz)
While at is also document other bits of the MDIO_MODE reg to have a
clear idea of what is actually applied there.
Documentation of some BITs is skipped as they are marked as reserved and
their usage is not clear (RES 11:9 GENPHY 16:13 RES1 19:17)

====================
net: ipa: simplify TX power handling
In order to deliver a packet to the IPA hardware, we must ensure
it is powered. We request power by calling pm_runtime_get(), and
its return value tells us the power state. We can't block in
ipa_start_xmit(), so if power isn't enabled we prevent further
transmit attempts by calling netif_stop_queue(). Power will
eventually become enabled, at which point we call netif_wake_queue()
to allow the transmit to be retried. When it does, the power should
be enabled, so the packet delivery can proceed.
The logic that handles this is convoluted, and was put in place
to address a race condition pointed out by Jakub Kicinski during
review. The fix addressed that race, as well as another one that
was found while investigating it:
b8e36e13ea ("net: ipa: fix TX queue race")
I have wanted to simplify this code ever since, and I'm pleased to
report that this series implements a much better solution that
avoids both race conditions.
The first race occurs between the ->ndo_start_xmit thread and the
runtime resume thread. If we find power is not enabled when
requested in ipa_start_xmit(), we stop queueing. But there's a
chance the runtime resume will enable queuing just before that,
leaving queueing stopped forever. A flag is used to ensure that
does not occur.
A second flag is used to prevent NETDEV_TX_BUSY from being returned
repeatedly during the small window between enabling queueing and
finishing power resume. This can happen if resume was underway when
pm_runtime_get() was called and completes immediately afterward.
This condition only exists because of the use of the first flag.
The fix is to disable transmit for *every* call to ipa_start_xmit(),
disabling it *before* calling pm_runtime_get(). This leaves three
cases:
- If the return value indicates power is not active (or is in
transition), queueing remains disabled--thereby avoiding
the race between disabling it and a concurrent power thread
enabling it.
- If pm_runtime_get() returns an error, we drop the packet and
re-enable queueing.
- Finally, if the hardware is powered, we re-enable queueing
before delivering the packet to the hardware.
So the first race is avoided. And as a result, the second condition
will not occur.
The first patch adds pointers to the TX and RX IPA endpoints in the
netdev private data. The second patch has netif_stop_queue() be
called for all packets; if pm_runtime_get() indicates power is
enabled (or an error), netif_wake_queue() is called to enable it
again. The third and fourth patches get rid of the STARTED and
STOPPED IPA power flags, as well as the power spinlock, because they
are no longer needed. The last three patches just eliminate some
trivial functions, open-coding them instead.

All ipa_power_modem_queue_wake() does is call netif_wake_queue()
on the modem netdev. There is no need to wrap that call in a
trivial function (and certainly not one defined in "ipa_power.c").
So get rid of ipa_power_modem_queue_wake(), and replace its one
caller with a direct call to netif_wake_queue(). Determine the
netdev pointer to use from the private TX endpoint's netdev pointer.

Currently the STOPPED IPA power flag is used to indicate that the
transmit queue has been stopped. Previously this was used to avoid
setting the STARTED flag unless the queue had already been stopped.
It meant transmit queuing would be enabled on resume if it was
stopped by the transmit path--and if so, it ensured it only got
enabled once.
We only stop the transmit queue in the transmit path. The STARTED
flag has been removed, and it causes no real harm to enable
transmits when they're already enabled. So we can get rid of
the STOPPED flag and call netif_wake_queue() unconditionally.
This makes the IPA power spinlock unnecessary, so it can be removed
as well.

A transmit on the modem netdev can only complete if the IPA hardware
is powered. Currently, if a transmit request arrives when the
hardware was not powered, further transmits are be stopped to allow
power-up to complete. Once power-up completes, transmits are once
again enabled.
Runtime resume can complete at the same time a transmit request is
being handled, and previously there was a race between stopping and
restarting transmits. The STARTED flag was used to ensure the
stop request in the transmit path was skipped if the start request
in the runtime resume path had already occurred.
Now, the queue is *always* stopped in the transmit path, *before*
determining whether power is ACTIVE. If power is found to already
be active (or if the socket buffer is gets dropped), transmit is
re-enabled. Otherwise it will (always) be enabled after runtime
resume completes.
The race between transmit and runtime resume no longer exists, so
there is no longer any need to maintain the STARTED flag.

There are a number of flags used in the IPA driver to attempt to
manage race conditions that can occur between runtime resume and
netdev transmit. If we disable TX before requesting power, we can
avoid these races entirely, simplifying things considerably.
This patch implements the main change, disabling transmit always in
the net_device->ndo_start_xmit() callback, then re-enabling it again
whenever we find power is active (or when we drop the skb).
The patches that follow will refactor the "old" code to the point
that most of it can be eliminated.

Netfilter fixes for net
1) TCP conntrack now only evaluates window negotiation for packets in
the REPLY direction, from Ryan Schaefer. Otherwise SYN retransmissions
trigger incorrect window scale negotiation. From Ryan Schaefer.
2) Restrict tunnel objects to NFPROTO_NETDEV which is where it makes sense
to use this object type.
3) Fix conntrack pick up from the middle of SCTP_CID_SHUTDOWN_ACK packets.
From Xin Long.
4) Another attempt from Jozsef Kadlecsik to address the slow down of the
swap command in ipset.
5) Replace a BUG_ON by WARN_ON_ONCE in nf_log, and consolidate check for
the case that the logger is NULL from the read side lock section.
6) Address lack of sanitization for custom expectations. Restrict layer 3
and 4 families to what it is supported by userspace.

In the arm random config file, kconfig option 'CONFIG_AEABI' is
disabled which results in adding the compiler flag '-mabi=apcs-gnu'.
This causes the compiler to add padding in virtchnl2_ptype
structure to align it to 8 bytes, resulting in the following
size check failure:
include/linux/build_bug.h:78:41: error: static assertion failed: "(6) == sizeof(struct virtchnl2_ptype)"
78 | #define __static_assert(expr, msg, ...) _Static_assert(expr, msg)

Avoid the compiler padding by using "__packed" structure
attribute for the virtchnl2_ptype struct. Also align the
structure by using "__aligned(2)" for better code optimization.

maintainers (NIPA) for running our kunit and selftests tests!
For the first patch, it took a bit of time to identify the root cause.
Some MPTCP Join selftest subtests have been "flaky", mostly in slow
environments. It appears to be due to the use of a TCP-specific helper
on an MPTCP socket. A fix for kernels >= v5.15.
Patches 2 to 4 add missing kernel config to support NetFilter tables
needed for IPTables commands. These kconfigs are usually enabled in
default configurations, but apparently not for all architectures.
Patches 2 and 3 can be backported up to v5.11 and the 4th one up to
v5.19.
Patch 5 increases the time limit for MPTCP selftests. It appears that
many CI's execute tests in a VM without acceleration supports, e.g. QEmu
without KVM. As a result, the tests take longer. Plus, there are more
and more tests. This patch modifies the timeout added in v5.18.
Patch 6 reduces the maximum rate and delay of the different links in
some Simult Flows selftest subtests. The goal is to let slow VMs reach
the maximum speed. The original rate was introduced in v5.11.
Patch 7 lets CI changing the prefix of the subtests titles, to be able
to run the same selftest multiple times with different parameters. With
different titles, tests will be considered as different and not override
previous results as it is the case with some CI envs. Subtests have been
introduced in v6.6.
Patch 8 and 9 make some MPTCP Join selftest subtests quicker by stopping
the transfer when the expected events have been seen. Patch 8 can be
backported up to v6.5.

Since the "Fixes" commits mentioned below, the newly added "userspace
pm" subtests of mptcp_join selftests are launching the whole transfer in
the background, do the required checks, then wait for the end of
transfer.
There is no need to wait longer, especially because the checks at the
end of the transfer are ignored (which is fine). This saves quite a few
seconds on slow environments.
While at it, use 'mptcp_lib_kill_wait()' helper everywhere, instead of
on a specific one with 'kill_tests_wait()'.

If a CI executes the same selftest multiple times with different
options, all results from the same subtests will have the same title,
which confuse the CI. With the same title printed in TAP, the tests are
considered as the same ones.
Now, it is possible to override this prefix by using MPTCP_LIB_KSFT_TEST
env var, and have a different title.
While at it, use 'basename' to remove the suffix as well instead of
using an extra 'sed'.

When running the simult_flow selftest in slow environments -- e.g. QEmu
without KVM support --, the results can be unstable. This selftest
checks if the aggregated bandwidth is (almost) fully used as expected.
To help improving the stability while still keeping the same validation
in place, the BW and the delay are reduced to lower the pressure on the
CPU.

On very slow environments -- e.g. when QEmu is used without KVM --,
mptcp_join.sh selftest can take a bit more than 20 minutes. Bump the
default timeout by 50% as it seems normal to take that long on some
environments.
When a debug kernel config is used, this selftest will take even longer,
but that's certainly not a common test env to consider for the timeout.
The Fixes tag that has been picked here is there simply to help having
this patch backported to older stable versions. It is difficult to point
to the exact commit that made some env reaching the timeout from time to
time.

Since the commit mentioned below, 'mptcp_join' selftests is using
IPTables to add rules to the Mangle table, only in IPv4.
This KConfig is usually enabled by default in many defconfig, but we
recently noticed that some CI were running our selftests without them
enabled.

When the MPTCP PM detects that a subflow is stale, all the packet
scheduler must re-inject all the mptcp-level unacked data. To avoid
acquiring unneeded locks, it first try to check if any unacked data
is present at all in the RTX queue, but such check is currently
broken, as it uses TCP-specific helper on an MPTCP socket.
Funnily enough fuzzers and static checkers are happy, as the accessed
memory still belongs to the mptcp_sock struct, and even from a
functional perspective the recovery completed successfully, as
the short-cut test always failed.
A recent unrelated TCP change - commit d5fed5addb ("tcp: reorganize
tcp_sock fast path variables") - exposed the issue, as the tcp field
reorganization makes the mptcp code always skip the re-inection.
Fix the issue dropping the bogus call: we are on a slow path, the early
optimization proved once again to be evil.
