====================
ethtool: rss: driver tweaks and netlink context dumps

This series is a semi-related collection of RSS patches.
Main point is supporting dumping RSS contexts via ethtool netlink.
At present additional RSS contexts can be queried one by one, and
assuming user know the right IDs. This series uses the XArray
added by Ed to provide netlink dump support for ETHTOOL_GET_RSS.

Patch 1 is a trivial selftest debug patch.
Patch 2 coverts mvpp2 for no real reason other than that I had
	a grand plan of converting all drivers at some stage.
Patch 3 removes a now moot check from mlx5 so that all tests
	can pass.
Patch 4 and 5 make a bit used for context support optional,
	for easier grepping of drivers which need converting
	if nothing else.
Patch 6 OTOH adds a new cap bit; some devices don't support
	using a different key per context and currently act
	in surprising ways.
Patch 7 and 8 update the RSS netlink code to use XArray.
Patch 9 and 10 add support for dumping contexts.
Patch 11 and 12 are small adjustments to spec and a new test.

I'm getting distracted with other work, so probably won't have
the time soon to complete next steps, but things which are missing
are (and some of these may be bad ideas):

 - better discovery

   Some sort of API to tell the user who many contexts the device
   can create. Upper bound, devices often share contexts between
   ports etc. so it's hard to tell exactly and upfront number of
   contexts for a netdev. But order of magnitude (4 vs 10s) may
   be enough for container management system to know whether to bother.

 - create/modify/delete via netlink

   The only question here is how to handle all the tricky IOCTL
   legacy. "No change" maps trivially to attribute not present.
   "reset" (indir_size = 0) probably needs to be a new NLA_FLAG?

 - better table size handling

   The current API assumes the LUT has fixed size, which isn't
   true for modern devices. We should have better APIs for the
   drivers to resize the tables, and in user facing API -
   the ability to specify pattern and min size rather than
   exact table expected (sort of like ethtool CLI already does).

 - recounted / socket-bound contexts

   Support for contexts which get "cleaned up" when their parent
   netlink socket gets closed. The major catch is that ntuple
   filters (which we don't currently track) depend on the context,
   so we need auto-removal for both.

v5:
 - fix build
v4: https://lore.kernel.org/20240809031827.2373341-1-kuba@kernel.org
 - adjust to the meaning of max context from net
v3: https://lore.kernel.org/20240806193317.1491822-1-kuba@kernel.org
 - quite a few code comments and commit message changes
 - mvpp2: fix interpretation of max_context_id (I'll take care of
   the net -> net-next merge as needed)
 - filter by ifindex in the selftest
v2: https://lore.kernel.org/20240803042624.970352-1-kuba@kernel.org
 - fix bugs and build in mvpp2

f6122900f4 ethtool: rss: support dumping RSS contexts
Now that we track RSS contexts in the core we can easily dump
them. This is a major introspection improvement, as previously
the only way to find all contexts would be to try all ids
(of which there may be 2^32 - 1).

Don't use the XArray iterators (like xa_for_each_start()) as they
do not move the index past the end of the array once done, which
caused multiple bugs in Netlink dumps in the past.

ec6e57beaf ethtool: rss: don't report key if device doesn't support it
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.

ce056504e2 ethtool: make ethtool_ops::cap_rss_ctx_supported optional
cap_rss_ctx_supported was created because the API for creating
and configuring additional contexts is mux'ed with the normal
RSS API. Presence of ops does not imply driver can actually
support rss_context != 0 (in fact drivers mostly ignore that
field). cap_rss_ctx_supported lets core check that the driver
is context-aware before calling it.

Now that we have .create_rxfh_context, there is no such
ambiguity. We can depend on presence of the op.
Make setting the bit optional.

f203fd85e6 eth: mvpp2: implement new RSS context API
Implement the separate create/modify/delete ops for RSS.

No problems with IDs - even tho RSS tables are per device
the driver already seems to allocate IDs linearly per port.
There's a translation table from per-port context ID
to device context ID.

mvpp2 doesn't have a key for the hash, it defaults to
an empty/previous indir table.

Note that there is no key at all, so we don't have to be
concerned with reporting the wrong one (which is addressed
by a patch later in the series).

Compile-tested only.

32316f676b net: mana: Fix RX buf alloc_size alignment and atomic op panic
The MANA driver's RX buffer alloc_size is passed into napi_build_skb() to
create SKB. skb_shinfo(skb) is located at the end of skb, and its alignment
is affected by the alloc_size passed into napi_build_skb(). The size needs
to be aligned properly for better performance and atomic operations.
Otherwise, on ARM64 CPU, for certain MTU settings like 4000, atomic
operations may panic on the skb_shinfo(skb)->dataref due to alignment fault.

To fix this bug, add proper alignment to the alloc_size calculation.

====================
net: dsa: vsc73xx: fix MDIO bus access and PHY opera

This series are extracted patches from net-next series [0].

The VSC73xx driver has issues with PHY configuration. This patch series
fixes most of them.

The first patch synchronizes the register configuration routine with the
datasheet recommendations.

Patches 2-3 restore proper communication on the MDIO bus. Currently,
the write value isn't sent to the MDIO register, and without a busy check,
communication with the PHY can be interrupted. This causes the PHY to
receive improper configuration and autonegotiation could fail.

The fourth patch removes the PHY reset blockade, as it is no longer
required.

After fixing the MDIO operations, autonegotiation became possible.
The last patch removes the blockade, which became unnecessary after
the MDIO operations fix.

9f9a726546 net: dsa: vsc73xx: allow phy resetting
Resetting the VSC73xx PHY was problematic because the MDIO bus, without
a busy check, read and wrote incorrect register values.

My investigation indicates that resetting the PHY only triggers changes
in configuration. However, improper register values written earlier
were only exposed after a soft reset.

The reset itself wasn't the issue; rather, the problem stemmed from
incorrect read and write operations.

A 'soft_reset' can now proceed normally. There are no reasons to keep
the VSC73xx from being reset.

This commit removes the reset blockade in the 'vsc73xx_phy_write'
function.

7006fe2f7f A set of x86 fixes:
- Fix 32-bit PTI for real. pti_clone_entry_text() is called twice, once
     before initcalls so that initcalls can use the user-mode helper and
     then again after text is set read only. Setting read only on 32-bit
     might break up the PMD mapping, which makes the second invocation of
     pti_clone_entry_text() find the mappings out of sync and failing.
 
     Allow the second call to split the existing PMDs in the user mapping
     and synchronize with the kernel mapping.
 
   - Don't make acpi_mp_wake_mailbox not read only after init as the mail
     box must be writable in the case that CPU hotplug operations happen
     after boot. Otherwise the attempt to start a CPU crashes with a write
     to read only memory.
 
   - Add a missing sanity check in mtrr_save_state() to ensure that the
     fixed MTRR MSRs are supported.
 
     Otherwise mtrr_save_state() ends up in a #GP, which is fixed up, but
     the WARN_ON() can bring systems down when panic on warn is set.

7270e931b5 Updates for time keeping:
- Fix a couple of issues in the NTP code where user supplied values are
     neither sanity checked nor clamped to the operating range. This results
     in integer overflows and eventualy NTP getting out of sync.
 
     According to the history the sanity checks had been removed in favor of
     clamping the values, but the clamping never worked correctly under all
     circumstances. The NTP people asked to not bring the sanity checks back
     as it might break existing applications.
 
     Make the clamping work correctly and add it where it's missing
 
   - If adjtimex() sets the clock it has to trigger the hrtimer subsystem so
     it can adjust and if the clock was set into the future expire timers if
     needed. The caller should provide a bitmask to tell hrtimers which
     clocks have been adjusted. adjtimex() uses not the proper constant and
     uses CLOCK_REALTIME instead, which is 0. So hrtimers adjusts only the
     clocks, but does not check for expired timers, which might make them
     expire really late. Use the proper bitmask constant instead.

This is v2 of the patch (now patches) adding support for ethtool
!autoneg while respecting the requirements of IEEE 802.3.

v2 fixes the build errors in the previous patch by first constifying
the "advertisement" argument to the linkmode functions that only
read from this pointer. It also fixes the incorrectly named
linkmode_set function.

6ff3cddc36 net: phylib: do not disable autoneg for fixed speeds >= 1G
We have an increasing number of drivers that are forcing
auto-negotiation to be enabled for speeds of 1G or faster.

It would appear that auto-negotiation is mandatory for speeds above
100M. In 802.3, Annex 40C's state diagrams seems to imply that
mr_autoneg_enable (BMCR AN ENABLE) doesn't affect whether or not the
AN state machines work for 1000base-T, and some PHY datasheets (e.g.
Marvell Alaska) state that disabling mr_autoneg_enable leaves AN
enabled but forced to 1G full duplex.

Other PHY datasheets imply that BMCR AN ENABLE should not be cleared
for >= 1G.

Thus, this should be handled in phylib rather than in each driver.

Rather than erroring out, arrange to implement the Marvell Alaska
solution but in software for all PHYs: generate an appropriate
single-speed advertisement for the requested speed, and keep AN
enabled to the PHY driver. However, to avoid userspace API breakage,
continue to report to userspace that we have AN disabled.

net: mvpp2: rework child node/port removal handling

These two patches used to be part of another series [1] that did not
apply to the networking tree without conflicts. This is therefore just a
partial resend with no code modifications, just rebased onto net/main.

a7b3274447 net: mvpp2: use device_for_each_child_node() to access device child nodes
The iterated nodes are direct children of the device node, and the
`device_for_each_child_node()` macro accounts for child node
availability.

`fwnode_for_each_available_child_node()` is meant to access the child
nodes of an fwnode, and therefore not direct child nodes of the device
node.

The child nodes within mvpp2_probe are not accessed outside the loops,
and the scoped version of the macro can be used to automatically
decrement the refcount on early exits.

Use `device_for_each_child_node()` and its scoped variant to indicate
device's direct child nodes.

e81d00a6b3 net: mvpp2: use port_count to remove ports
As discussed in [1], there is no need to iterate over child nodes to
remove the list of ports. Instead, a loop up to `port_count` ports can
be used, and is in fact more reliable in case the child node
availability changes.

The suggested approach removes the need for the `fwnode` and
`port_fwnode` variables in mvpp2_remove() as well.

80d021bc57 Merge branch 'bnxt_en-fix-queue-reset-when-queue-active'
David Wei says:

====================
fix bnxt_en queue reset when queue is active

The current bnxt_en queue API implementation is buggy when resetting a
queue that has active traffic. The problem is that there is no FW
involved to stop the flow of packets and relying on napi_disable() isn't
enough.

To fix this, call bnxt_hwrm_vnic_update() with MRU set to 0 for both the
default and the ntuple vnic to stop the flow of packets. This works for
any Rx queue and not only those that have ntuple rules since every Rx
queue is either in the default or the ntuple vnic.

For bnxt_hwrm_vnic_update() to work, proper flushing must be done by the
FW. A FW flag is there to indicate support and queue_mgmt_ops is keyed
behind this.

The first three patches are from Michael Chan and adds the prerequisite
vnic functions and FW flags indicating that it will properly flush
during vnic update.

Tested on BCM957504 while iperf3 is active:

1. Reset a queue that has an ntuple rule steering flow into it
2. Reset all queues in order, one at a time

In both cases the flow is not interrupted.

Sending this to net-next as there is no in-tree kernel consumer of queue
API just yet, and there is a patch that changes when the queue_mgmt_ops
is registered.

v3:
 - include patches from Michael Chan that adds a FW flag for vnic flush
   capability
 - key support for queue_mgmt_ops behind this new flag

v2:
 - split setting vnic->mru into a separate patch (Wojciech)
 - clarify why napi_enable()/disable() is removed

97cbf3d0ac bnxt_en: only set dev->queue_mgmt_ops if supported by FW
The queue API calls bnxt_hwrm_vnic_update() to stop/start the flow of
packets, which can only properly flush the pipeline if FW indicates
support.

Add a macro BNXT_SUPPORTS_QUEUE_API that checks for the required flags
and only set queue_mgmt_ops if true.

b9d2956e86 bnxt_en: stop packet flow during bnxt_queue_stop/start
The current implementation when resetting a queue while packets are
flowing puts the queue into an inconsistent state.

There needs to be some synchronisation with the FW. Add calls to
bnxt_hwrm_vnic_update() to set the MRU for both the default and ntuple
vnic during queue start/stop. When the MRU is set to 0, flow is stopped.
Each Rx queue belongs to either the default or the ntuple vnic.

With calling bnxt_hwrm_vnic_update() the calls to napi_enable() and
napi_disable() must be removed for reset to work on a queue that has
active traffic flowing e.g. iperf3.
