Add a fairly complete example of rt-link usage. If run without any
arguments it simply lists the interfaces and some of their attrs.
If run with an arg it tries to create and delete a netkit device.
1 # ./tools/net/ynl/samples/rt-link 1
2 Trying to create a Netkit interface
3 Testing error message for policy being bad:
4 Kernel error: 'Provided default xmit policy not supported' (bad attribute: .linkinfo.data(netkit).policy)
5 1: lo: mtu 65536
6 2: wlp0s1: mtu 1500
7 3: enp0s13: mtu 1500
8 4: dummy0: mtu 1500 kind dummy altname one two
9 5: nk0: mtu 1500 kind netkit primary 0 policy forward
10 6: nk1: mtu 1500 kind netkit primary 1 policy blackhole
11 Trying to delete a Netkit interface (ifindex 6)
Sample creates the device first, it sets an invalid value for a netkit
attribute to trigger reverse parsing. Line 4 shows the error with the
attribute path correctly generated by YNL.
Then sample fixes the bad attribute and re-issues the request, with
NLM_F_ECHO set. This flag causes the notification to be looped back
to the initiating socket (our socket). Sample parses this notification
to save the ifindex of the created netkit.
Sample then proceeds to list the devices. Line 8 above shows a dummy
device with two alt names. Lines 9 and 10 show the netkit devices
the sample itself created.
The "primary" and "policy" attrs are from inside the netkit submsg.
The string values are auto-generated for the enums by YNL.
To clean up sample deletes the interface it created (line 11).

Reverse parsing lets YNL convert bad and missing attr pointers
from extack into a string like "missing attribute nest1.nest2.attr_name".
It's a feature that's unique to YNL C AFAIU (even the Python YNL
can't do nested reverse parsing). Add support for reverse-parsing
of sub-messages.
To simplify the logic and the code annotate the type policies
with extra metadata. Mark the selectors and the messages with
the information we need. We assume that key / selector always
precedes the sub-message while parsing (and also if there are
multiple sub-messages like in rt-link they are interleaved
selector 1 ... submsg 1 ... selector 2 .. submsg 2, not
selector 1 ... selector 2 ... submsg 1 ... submsg 2).
The rt-link sample in a subsequent changes shows reverse parsing
of sub-messages in action.

Adjust parsing and rendering appropriately to make sub-messages work.
Rendering is pretty trivial, as the submsg -> netlink conversion looks
like rendering a nest in which only one attr was set. Only trick
is that we use the enum value of the sub-message rather than the nest
as the type, and effectively skip one layer of nesting. A real double
nested struct would look like this:
[SELECTOR]
[SUBMSG]
[NEST]
[MSG1-ATTR]
A submsg "is" the nest so by skipping I mean:
[SELECTOR]
[SUBMSG]
[MSG1-ATTR]
There is no extra validation in YNL if caller has set the selector
matching the submsg type (e.g. link type = "macvlan" but the nest
attrs are set to carry "veth"). Let the kernel handle that.
Parsing side is a little more specialized as we need to render and
insert a new kind of function which switches between what to parse
based on the selector. But code isn't too complicated.

The easiest (or perhaps only sane) way to support submessages in C
is to treat them as if they were nests. Build fake attributes to
that effect in the codegen. Render the submsg as a big nest of all
possible values.
With this in place the main missing part is to hook in the switch
which selects how to parse based on the key.

Prepare for constructing Struct() instances which represent
sub-messages rather than nested attributes.
Restructure the code / indentation to more easily insert
a case where nested reference comes from annotation other
than the 'nested-attributes' property. Make sure we don't
construct the Struct() object from scratch in multiple
places as the constructor will soon have more arguments.
This should cause no functional change.

Pull drm fixes from Dave Airlie:
"Weekly drm fixes, I'll be honest and say I think this is larger than
I'd prefer at this point, the main blow out point is that xe has two
larger fixes.
One is a fix for active context utilisation reporting, it's for a
reported regression and will end up in stable anyways, so I don't see
any point in holding it up.
The second is a fix for mixed cpu/gpu atomics, which are currently
broken, but are also not something your average desktop/laptop user is
going to hit in normal operation, and having them fixed now is better
than threading them through stable later.
Other than those, it's mostly the usual, a bunch of amdgpu randoms and
a few other minor fixes.

Currently, when device mtu is updated, vmxnet3 updates netdev mtu, quiesces
the device and then reactivates it for the ESXi to know about the new mtu.
So, technically the OS stack can start using the new mtu before ESXi knows
about the new mtu.
This can lead to issues for TSO packets which use mss as per the new mtu
configured. This patch fixes this issue by moving the mtu write after
device quiesce.

RFS can exhibit lower performance for workloads using short-lived
flows and a small set of 4-tuple.
This is often the case for load-testers, using a pair of hosts,
if the server has a single listener port.
Typical use case :
Server : tcp_crr -T128 -F1000 -6 -U -l30 -R 14250
Client : tcp_crr -T128 -F1000 -6 -U -l30 -c -H server | grep local_throughput
This is because RFS global hash table contains stale information,
when the same RSS key is recycled for another socket and another cpu.
Make sure to undo the changes and go back to initial state when
a flow is disconnected.
Performance of the above test is increased by 22 %,
going from 372604 transactions per second to 457773.

When netfilter defrag hooks are loaded (due to the presence of conntrack
rules, for example), fragmented packets entering the bridge will be
defragged by the bridge's pre-routing hook (br_nf_pre_routing() ->
ipv4_conntrack_defrag()).
Later on, in the bridge's post-routing hook, the defragged packet will
be fragmented again. If the size of the largest fragment is larger than
what the kernel has determined as the destination MTU (using
ip_skb_dst_mtu()), the defragged packet will be dropped.
Before commit ac6627a28dbf ("net: ipv4: Consolidate ipv4_mtu and
ip_dst_mtu_maybe_forward"), ip_skb_dst_mtu() would return dst_mtu() as
the destination MTU. Assuming the dst entry attached to the packet is
the bridge's fake rtable one, this would simply be the bridge's MTU (see
fake_mtu()).
However, after above mentioned commit, ip_skb_dst_mtu() ends up
returning the route's MTU stored in the dst entry's metrics. Ideally, in
case the dst entry is the bridge's fake rtable one, this should be the
bridge's MTU as the bridge takes care of updating this metric when its
MTU changes (see br_change_mtu()).
Unfortunately, the last operation is a no-op given the metrics attached
to the fake rtable entry are marked as read-only. Therefore,
ip_skb_dst_mtu() ends up returning 1500 (the initial MTU value) and
defragged packets are dropped during fragmentation when dealing with
large fragments and high MTU (e.g., 9k).
Fix by moving the fake rtable entry's metrics to be per-bridge (in a
similar fashion to the fake rtable entry itself) and marking them as
writable, thereby allowing MTU changes to be reflected.
Fixes: 62fa8a846d7d ("net: Implement read-only protection and COW'ing of metrics.")
Fixes: 33eb9873a283 ("bridge: initialize fake_rtable metrics")

The pointer arithmentic for accessing the tail tag only works
for linear skbs.
For nonlinear skbs, it reads uninitialized memory inside the
skb headroom, essentially randomizing the tag. I have observed
it gets set to 6 most of the time.
Example where ksz9477_rcv thinks that the packet from port 1 comes from port 6
(which does not exist for the ksz9896 that's in use), dropping the packet.

This patch synchronizes code that accesses from both user-space
and IRQ contexts. The `get_stats()` function can be called from both
context.
`dev->stats.tx_errors` and `dev->stats.collisions` are also updated
in the `tx_errors()` function. Therefore, these fields must also be
protected by synchronized.
There is no code that accessses `dev->stats.tx_errors` between the
previous and updated lines, so the updating point can be moved.

CONFIG_INIT_STACK_ALL_ZERO introduces a performance cost by
zero-initializing all stack variables on function entry. The mlx5 XDP
RX path previously allocated a struct mlx5e_xdp_buff on the stack per
received CQE, resulting in measurable performance degradation under
this config.
This patch reuses a mlx5e_xdp_buff stored in the mlx5e_rq struct,
avoiding per-CQE stack allocations and repeated zeroing.
With this change, XDP_DROP and XDP_TX performance matches that of
kernels built without CONFIG_INIT_STACK_ALL_ZERO.
Performance was measured on a ConnectX-6Dx using a single RX channel
(1 CPU at 100% usage) at ~50 Mpps. The baseline results were taken from
net-next-6.15.
Stack zeroing disabled:
- XDP_DROP:
* baseline: 31.47 Mpps
* baseline + per-RQ allocation: 32.31 Mpps (+2.68%)
- XDP_TX:
* baseline: 12.41 Mpps
* baseline + per-RQ allocation: 12.95 Mpps (+4.30%)
Stack zeroing enabled:
- XDP_DROP:

* baseline + per-RQ allocation: 32.27 Mpps (+32.7%)

The debugfs summary output could access uninitialized elements in
the freq_in[] and signal_out[] arrays, causing NULL pointer
dereferences and triggering a kernel Oops (page_fault_oops).
This patch adds u8 fields (nr_freq_in, nr_signal_out) to track the
number of initialized elements, with a maximum of 4 per array.
The summary output functions are updated to respect these limits,
preventing out-of-bounds access and ensuring safe array handling.
Widen the label variables because the change confuses GCC about
max length of the strings.

Jens reported that the sanity checks added to the new ps883x USB retimer
driver breaks USB and display on the HP X14. Turns out the X14 only has
a retimer on one of the ports, but this initially went unnoticed due to
the missing sanity check (and error handling) in the retimer driver.
Drop the non-existing retimer from the devicetree to enable the second
USB port and the display subsystem.
Note that this also matches the ACPI tables.

The Linux client assumes that all filehandles are non-volatile for
renames within the same directory (otherwise sillyrename cannot work).
However, the existence of the Linux 'subtree_check' export option has
meant that nfs_rename() has always assumed it needs to flush writes
before attempting to rename.
Since NFSv4 does allow the client to query whether or not the server
exhibits this behaviour, and since knfsd does actually set the
appropriate flag when 'subtree_check' is enabled on an export, it
should be OK to optimise away the write flushing behaviour in the cases
where it is clearly not needed.

pm_runtime_put_autosuspend() schedules a hrtimer to expire
at "dev->power.timer_expires". If the hrtimer's callback,
pm_suspend_timer_fn(), observes that the current time equals
"dev->power.timer_expires", it unexpectedly bails out instead of
proceeding with runtime suspend.
pm_suspend_timer_fn():
if (expires > 0 && expires < ktime_get_mono_fast_ns()) {
dev->power.timer_expires = 0;
rpm_suspend(..)
}
Additionally, as ->timer_expires is not cleared, all the future auto
suspend requests will not schedule hrtimer to perform auto suspend.
rpm_suspend():
if ((rpmflags & RPM_AUTO) &&...) {
if (!(dev->power.timer_expires && ...) { <-- this will fail.
hrtimer_start_range_ns(&dev->power.suspend_timer,...);
}
}
Fix this by as well checking if current time reaches the set expiration.

Use MGLRU's debugfs interface to do access tracking instead of
page_idle. The logic to use the page_idle bitmap is left in, as it is
useful for kernels that do not have MGLRU built in.
When MGLRU is enabled, page_idle will report pages as still idle even
after being accessed, as MGLRU doesn't necessarily clear the Idle folio
flag when accessing an idle page, so the test will not attempt to use
page_idle if MGLRU is enabled but otherwise not usable.
Aging pages with MGLRU is much faster than marking pages as idle with
page_idle.

Since dynamic VLAN traffic is software encrypted and encapsulated,
mac80211 handles the duplication on each link for MLO dynamic VLAN
multicast.
Currently in ath12k_mac_op_tx(), all multicast frames are duplicated
and are assigned a mcbc_gsn. This is causing dynamic VLAN multicast
traffic to be dropped in hardware.
Prevent dynamic VLAN multicast traffic from being duplicated again in
the driver. Check if incoming packet is a dynamic VLAN packet and
avoid defaulting to multicast conditional.

To mitigate this issue, enable AST index-based address search during
transmission in station mode. This AST index-based search is not
enabled in AP mode due to the complexity involved in fetching peer
information.
Implement changes to retrieve the offset of ast_idx/ast_hash values

In ath12k_dp_mon_rx_merg_msdus(), will set packet offset to 8. This is a
right value for QCN9274.
But WCN7850 use different hardware rings for monitor mode because it
doesn't have RX MON component. So the packet offset is different. With
current offset, upper-layer application will failed to parse the payload
correctly.
Should use different value for those who don't have RX MON component.

WCN7850 uses error dst ring as mon dest ring. Each time hardware
receives a packet, will fill the payload into mon dest ring.
The mon dest ring may store many MSDUs, which belonged to different
MPDUs. Need to retrieve MSDUs based on the PPDU ID, only processing the
MSDUs with same PPDU ID each time.
The PPDU ID is used in cycles, the difference between the PPDU IDs
of the two rings must be checked. If the status PPDU ID minus the
dest PPDU ID is greater than 20000, it is considered a wrap-around
case.
After reaping the mon dest ring, should prepare packet and deliver it to
mac80211 when status PPDU ID is equal to dest PPDU ID. Then start to
process next PPDU if exists.
But if dest PPDU ID > status PPDU ID, should hold on to mon dest ring
processing. If it exceeds 16 consecutive times, status PPDU ID will be
forcibly set to dest PPDU ID to avoid backpressure issue.

This is not right. Because all halphy descriptions are little endian.
So use le32_get_bits for HAL_RX_MSDU_PKT_LENGTH_GET.

WCN7850 uses monitor status ring to store status buffer. Status buffer
contains many TLVs such as MPDU START/END. From these TLVs, can get
necessary information about related payload, such as PPDU ID.
Add helper function to reap status buffer from monitor status ring so
that can parse TLVs later by ath12k_dp_mon_parse_rx_dest().

Monitor status ring interrupt is configured in previous patch. So add
handler function __ath12k_dp_mon_process_ring() for monitor mode.
Will implement detail processing in patch 7 and 10.
