Commit cc34acd577f1 ("docs: net: document new locking reality")
introduced netif_ vs dev_ function semantics: the former expects locked
netdev, the latter takes care of the locking. We don't strictly
follow this semantics on either side, but there are more dev_xxx handlers
now that don't fit. Rename them to netif_xxx where appropriate.
Note that one dev_set_threaded call still remains in mt76 for debugfs file.

Add support for ETHTOOL_SRXFH (setting hashing fields) in RSS_SET.
The tricky part is dealing with symmetric hashing. In netlink user
can change the hashing fields and symmetric hash in one request,
in IOCTL the two used to be set via different uAPI requests.
Since fields and hash function config are still separate driver
callbacks - changes to the two are not atomic. Keep things simple
and validate the settings against both pre- and post- change ones.
Meaning that we will reject the config request if user tries
to correct the flow fields and set input_xfrm in one request,
or disables input_xfrm and makes flow fields non-symmetric.
We can adjust it later if there's a real need. Starting simple feels
right, and potentially partially applying the settings isn't nice,
either.

Support setting RSS hash function / algo via ethtool Netlink.
Like IOCTL we don't validate that the function is within the
range known to the kernel. The drivers do a pretty good job
validating the inputs, and the IDs are technically "dynamically
queried" rather than part of uAPI.
Only change should be that in Netlink we don't support user
explicitly passing ETH_RSS_HASH_NO_CHANGE (0), if no change
is requested the attribute should be absent.
The ETH_RSS_HASH_NO_CHANGE is retained in driver-facing
API for consistency (not that I see a strong reason for it).

Add initial support for RSS_SET, for now only operations on
the indirection table are supported.
Unlike the ioctl don't check if at least one parameter is
being changed. This is how other ethtool-nl ops behave,
so pick the ethtool-nl consistency vs copying ioctl behavior.
There are two special cases here:
1) resetting the table to defaults;
2) support for tables of different size.
For (1) I use an empty Netlink attribute (array of size 0).
(2) may require some background. AFAICT a lot of modern devices
allow allocating RSS tables of different sizes. mlx5 can upsize
its tables, bnxt has some "table size calculation", and Intel
folks asked about RSS table sizing in context of resource allocation
in the past. The ethtool IOCTL API has a concept of table size,
but right now the user is expected to provide a table exactly
the size the device requests. Some drivers may change the table
size at runtime (in response to queue count changes) but the
user is not in control of this. What's not great is that all
RSS contexts share the same table size. For example a device
with 128 queues enabled, 16 RSS contexts 8 queues in each will
likely have 256 entry tables for each of the 16 contexts,
while 32 would be more than enough given each context only has
8 queues. To address this the Netlink API should avoid enforcing
table size at the uAPI level, and should allow the user to express
the min table size they expect.
To fully solve (2) we will need more driver plumbing but
at the uAPI level this patch allows the user to specify
a table size smaller than what the device advertises. The device
table size must be a multiple of the user requested table size.
We then replicate the user-provided table to fill the full device
size table. This addresses the "allow the user to express the min
table size" objective, while not enforcing any fixed size.
From Netlink perspective .get_rxfh_indir_size() is now de facto
the "max" table size supported by the device.
We may choose to support table replication in ethtool, too,
when we actually plumb this thru the device APIs.
Initially I was considering moving full pattern generation
to the kernel (which queues to use, at which frequency and
what min sequence length). I don't think this complexity
would buy us much and most if not all devices have pow-2
table sizes, which simplifies the replication a lot.

Pull networking fixes from Jakub Kicinski:
"Including fixes from Bluetooth, CAN, WiFi and Netfilter.
More code here than I would have liked. That said, better now than
next week. Nothing particularly scary stands out. The improvement to
the OpenVPN input validation is a bit large but better get them in
before the code makes it to a final release. Some of the changes we
got from sub-trees could have been split better between the fix and
-next refactoring, IMHO, that has been communicated.
We have one known regression in a TI AM65 board not getting link. The
investigation is going a bit slow, a number of people are on vacation.
We'll try to wrap it up, but don't think it should hold up the
release.
Current release - fix to a fix:
- Bluetooth: L2CAP: fix attempting to adjust outgoing MTU, it broke
some headphones and speakers
Current release - regressions:
- wifi: ath12k: fix packets received in WBM error ring with REO LUT
enabled, fix Rx performance regression
- wifi: iwlwifi:
- fix crash due to a botched indexing conversion
- mask reserved bits in chan_state_active_bitmap, avoid FW assert()
Current release - new code bugs:
- nf_conntrack: fix crash due to removal of uninitialised entry
- eth: airoha: fix potential UaF in airoha_npu_get()
Previous releases - regressions:
- net: fix segmentation after TCP/UDP fraglist GRO
- af_packet: fix the SO_SNDTIMEO constraint not taking effect and a
potential soft lockup waiting for a completion
- rpl: fix UaF in rpl_do_srh_inline() for sneaky skb geometry
- virtio-net: fix recursive rtnl_lock() during probe()
- eth: stmmac: populate entire system_counterval_t in get_time_fn()
- eth: libwx: fix a number of crashes in the driver Rx path
- hv_netvsc: prevent IPv6 addrconf after IFF_SLAVE lost that meaning
Previous releases - always broken:
- mptcp: fix races in handling connection fallback to pure TCP
- rxrpc: assorted error handling and race fixes
- sched: another batch of "security" fixes for qdiscs (QFQ, HTB)
- tls: always refresh the queue when reading sock, avoid UaF
- phy: don't register LEDs for genphy, avoid deadlock
- Bluetooth: btintel: check if controller is ISO capable on
btintel_classify_pkt_type(), work around FW returning incorrect
capabilities
Misc:
- make OpenVPN Netlink input checking more strict before it makes it
to a final release
- wifi: cfg80211: remove scan request n_channels __counted_by, it's
only yielding false positives"

Implement the PCIe Congestion Event notifier which triggers a work item
to query the PCIe Congestion Event object. The result of the congestion
state is reflected in the new ethtool stats:
* pci_bw_inbound_high: the device has crossed the high threshold for
inbound PCIe traffic.
* pci_bw_inbound_low: the device has crossed the low threshold for
inbound PCIe traffic
* pci_bw_outbound_high: the device has crossed the high threshold for
outbound PCIe traffic.
* pci_bw_outbound_low: the device has crossed the low threshold for
outbound PCIe traffic
The high and low thresholds are currently configured at 90% and 75%.
These are hysteresis thresholds which help to check if the
PCI bus on the device side is in a congested state.
If low + 1 = high then the device is in a congested state. If low == high
then the device is not in a congested state.
The counters are also documented.
A follow-up patch will make the thresholds configurable.

The netiucv driver creates TCP/IP interfaces over IUCV between Linux
guests on z/VM and other z/VM entities.
Rationale for removal:
- NETIUCV connections are only supported for compatibility with
earlier versions and not to be used for new network setups,
since at least Linux kernel 4.0.
- No known active users, use cases, or product dependencies
- The driver is no longer relevant for z/VM networking;
preferred methods include:
* Device pass-through (e.g., OSA, RoCE)
* z/VM Virtual Switch (VSWITCH)
The IUCV mechanism itself remains supported and is actively used
via AF_IUCV, hvc_iucv, and smsg_iucv.

Netlink ops do not expect all attributes to be always set, however
this condition is not explicitly coded any where, leading the user

A net device has a threaded sysctl that can be used to enable threaded
NAPI polling on all of the NAPI contexts under that device. Allow
enabling threaded NAPI polling at individual NAPI level using netlink.
Extend the netlink operation `napi-set` and allow setting the threaded
attribute of a NAPI. This will enable the threaded polling on a NAPI
context.
Add a test in `nl_netdev.py` that verifies various cases of threaded
NAPI being set at NAPI and at device level.

Implement ETHTOOL_GRXFH over Netlink. The number of flow types is
reasonable (around 20) so report all of them at once for simplicity.
Do not maintain the flow ID mapping with ioctl at the uAPI level.
This gives us a chance to clean up the confusion that come from
RxNFC vs RxFH (flow direction vs hashing) in the ioctl.
Try to align with the names used in ethtool CLI, they seem to have
stood the test of time just fine. One annoyance is that we still
call L4 ports the weird names, but I guess they also apply to IPSec
(where they cover the SPI) so it is what it is.

In preparation for MT7988 and RSS/LRO allow the interrupt-names
property.
In this way driver can request the interrupts by name which is much
more readable in the driver code and SoC's dtsi than relying on a
specific order.
Frame-engine-IRQs (fe0..3):
MT7621, MT7628: 1 FE-IRQ
MT7622, MT7623: 3 FE-IRQs (only two used by the driver for now)
MT7981, MT7986: 4 FE-IRQs (only two used by the driver for now)
RSS/LRO IRQs (pdma0..3) additional only on Filogic (MT798x) with
count of 4. So all IRQ-names (8) for Filogic.
Set boundaries for all compatibles same as irq count.

This patch provides a setsockopt method to let applications leverage to
adjust how many descs to be handled at most in one send syscall. It
mitigates the situation where the default value (32) that is too small
leads to higher frequency of triggering send syscall.
Considering the prosperity/complexity the applications have, there is no
absolutely ideal suggestion fitting all cases. So keep 32 as its default
value like before.
The patch does the following things:
- Add XDP_MAX_TX_SKB_BUDGET socket option.
- Set max_tx_budget to 32 by default in the initialization phase as a
per-socket granular control.
- Set the range of max_tx_budget as [32, xs->tx->nentries].
The idea behind this comes out of real workloads in production. We use a
user-level stack with xsk support to accelerate sending packets and
minimize triggering syscalls. When the packets are aggregated, it's not
hard to hit the upper bound (namely, 32). The moment user-space stack
fetches the -EAGAIN error number passed from sendto(), it will loop to try
again until all the expected descs from tx ring are sent out to the driver.
Enlarging the XDP_MAX_TX_SKB_BUDGET value contributes to less frequency of
sendto() and higher throughput/PPS.
Here is what I did in production, along with some numbers as follows:
For one application I saw lately, I suggested using 128 as max_tx_budget
because I saw two limitations without changing any default configuration:
1) XDP_MAX_TX_SKB_BUDGET, 2) socket sndbuf which is 212992 decided by
net.core.wmem_default. As to XDP_MAX_TX_SKB_BUDGET, the scenario behind
this was I counted how many descs are transmitted to the driver at one
time of sendto() based on [1] patch and then I calculated the
possibility of hitting the upper bound. Finally I chose 128 as a
suitable value because 1) it covers most of the cases, 2) a higher
number would not bring evident results. After twisting the parameters,
a stable improvement of around 4% for both PPS and throughput and less
resources consumption were found to be observed by strace -c -p xxx:
1) %time was decreased by 7.8%
2) error counter was decreased from 18367 to 572

This reverts commit ad6b26b6a0a79166b53209df2ca1cf8636296382.
This commit introduces per-memcg/task NUMA balance statistics, but
unfortunately it introduced a NULL pointer exception due to the following
race condition: After a swap task candidate was chosen, its mm_struct
pointer was set to NULL due to task exit. Later, when performing the
actual task swapping, the p->mm caused the problem.
CPU0 CPU1
:
...
task_numa_migrate
task_numa_find_cpu
task_numa_compare
# a normal task p is chosen
env->best_task = p
# p exit:
exit_signals(p);
p->flags |= PF_EXITING
exit_mm
p->mm = NULL;
migrate_swap_stop
__migrate_swap_task((arg->src_task, arg->dst_cpu)
count_memcg_event_mm(p->mm, NUMA_TASK_SWAP)# p->mm is NULL
task_lock() should be held and the PF_EXITING flag needs to be checked to
prevent this from happening. After discussion, the conclusion was that
adding a lock is not worthwhile for some statistics calculations. Revert
the change and rely on the tracepoint for this purpose.

Some Broadcom PHYs are capable to operate in simplified MII mode,
without TXER, RXER, CRS and COL signals as defined for the MII.
The MII-Lite mode can be used on most Ethernet controllers with full
MII interface by just leaving the input signals (RXER, CRS, COL)
inactive. The absence of COL signal makes half-duplex link modes
impossible but does not interfere with BroadR-Reach link modes on
Broadcom PHYs, because they are all full-duplex only.
Add new interface type "mii-lite" to phy-connection-type enum.

Microchip Azurite ZL3073x represents chip family providing DPLL
and optionally PHC (PTP) functionality. The chips can be connected
be connected over I2C or SPI bus.
They have the following characteristics:
* up to 5 separate DPLL units (channels)
* 5 synthesizers
* 10 input pins (references)
* 10 outputs
* 20 output pins (output pin pair shares one output)
* Each reference and output can operate in either differential or
single-ended mode (differential mode uses 2 pins)
* Each output is connected to one of the synthesizers
* Each synthesizer is driven by one of the DPLL unit
The device uses 7-bit addresses and 8-bits values. It exposes 8-, 16-,
32- and 48-bits registers in address range <0x000,0x77F>. Due to 7bit
addressing, the range is organized into pages of 128 bytes, with each
page containing a page selector register at address 0x7F.
For reading/writing multi-byte registers, the device supports bulk
transfers.
Add basic functionality to access device registers, probe functionality
both I2C and SPI cases and add devlink support to provide info and
to set clock ID parameter.

The DPLL (device phase-locked loop) is a device used for precise clock
synchronization in networking and telecom hardware.
The device includes one or more DPLLs (channels) and one or more
physical input/output pins.
Each DPLL channel is used either to provide a pulse-per-clock signal or
to drive an Ethernet equipment clock.
The input and output pins have the following properties:
* label: specifies board label
* connection type: specifies its usage depending on wiring
* list of supported or allowed frequencies: depending on how the pin
is connected and where)
* embedded sync capability: indicates whether the pin supports this

In LACP mode with broadcast_neighbor enabled, after LACP protocol
recovery, the port can transmit packets. However, if the bond port
doesn't send gratuitous ARP/ND packets to the switch, the switch
won't return packets through the current interface. This causes
traffic imbalance. To resolve this issue, when LACP protocol recovers,
send ARP/ND packets if broadcast_neighbor is enabled.
