Merge tag 'net-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"The zero-copy changes are relatively significant, but regression risk
should be contained. The feature needs to be used to cause trouble.

Also it feels like we got an order of magnitude more semi-automated
"refactoring" chaff than usual, I wonder if it's just us.

Core & protocols:

- Support Device Memory TCP, ability to zero-copy receive TCP
payloads to a DMABUF region of memory while packet headers land
separately in normal kernel buffers, and TCP processes then as
usual.

- The ability to read the PTP PHC (Physical Hardware Clock) alongside
MONOTONIC_RAW timestamps with PTP_SYS_OFFSET_EXTENDED. Previously
only CLOCK_REALTIME was supported.

- Allow matching on all bits of IP DSCP for routing decisions.
Previously we only supported on matching TOS bits in IPv4 which is
a narrower interpretation of the same header field.

- Increase the range of weights used for multi-path routing from
8 bits to 16 bits.

- Add support for IPv6 PIO p flag in the Prefix Information Option
per draft-ietf-6man-pio-pflag.

- IPv6 IOAM6 support for new tunsrc encap mode for better
performance.

- Detect destinations which blackhole MPTCP traffic and avoid
initiating MPTCP connections to them for a certain period of time,
1h by default.

- Improve IPsec control path performance by removing the inexact
policies list.

- AF_VSOCK: add support for SIOCOUTQ ioctl.

- Add enum for reasons TCP reset was sent for easier tracing.

- Add SMC ringbufs usage statistics.

Drivers:

- Handle netconsole setup failures more gracefully, don't fail
loading, retain the specified target as disabled.

- Extend bonding's IPsec offload pass thru capabilities (ESN, stats).

Filtering:

- Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case
when long-lived sockets miss a chance to set additional callbacks
if a sockops program was not attached early in their lifetime.

- Support using BPF skb helpers in tracepoints.

- Conntrack Netlink: support CTA_FILTER for flush.

- Improve SCTP support in nfnetlink_queue.

- Improve performance of large nftables flush transactions.

Things we sprinkled into general kernel code:

- selftests: support setting an "interpreter" for script files; make
it easy to run as separate cases tests where one "interpreter" is
fed various test descriptions (in our case packet sequences).

Driver API:

- Extend core and ethtool APIs to support many PHYs connected to a
single interface (PHY topologies).

- Extend cable diagnostics to specify whether Time Domain
Reflectometry (TDR) or Active Link Cable Diagnostic (ALCD) was
used.

- Add library for implementing MAC-PHY Ethernet drivers for SPI
devices compatible with Open Alliance 10BASE-T1x MAC-PHY Serial
Interface (TC6) standard.

- Add helpers to the PHY framework, for PHYs following the Open
Alliance standards:
- 1000BaseT1 link settings
- cable test and diagnostics

- Support listing / dumping all allocated RSS contexts.

- Add configuration for frequency Embedded SYNC in DPLL, which
magically embeds sync pulses into Ethernet signaling.

not suddenly appear in everyone's mailbox one day. I apologize for
this. (The email content mainly agrees with Serge's suggestion.)

v14:

Because Loongson GMAC can be also found with the 8-channels AV feature
enabled, we'll need to reconsider the patches logic and thus the
commit logs too. As Serge's comments and Russell's comments:

v13:

* Sorry, we have clarified some things in the past 10 days. I did not
give you a clear reply to the following questions in v12, so I need
to reply again:

1. The current LS2K2000 also have a GMAC(and two GNET) that supports 8
channels, so we have to reconsider the initialization of
tx/rx_queues_to_use into probe();

2. In v12, we disagreed on the loongson_dwmac_msi_config method, but I changed
it based on Serge's comments(If I understand correctly):
if (dev_of_node(&pdev->dev)) {
ret = loongson_dwmac_dt_config(pdev, plat, &res);
}

if (ld->loongson_id == DWMAC_CORE_LS2K2000) {
ret = loongson_dwmac_msi_config(pdev, plat, &res);
} else {
ret = loongson_dwmac_intx_config(pdev, plat, &res);
}

3. Our priv->dma_cap.pcs is false, so let's use PHY_INTERFACE_MODE_NA;

4. Our GMAC does not support Delay, so let's use PHY_INTERFACE_MODE_RGMII_ID,
the current dts is wrong, a fix patch will be sent to the LoongArch list
later.

Others:
* Re-split a part of the patch (it seems we do this with every version);
* Copied Serge's comments into the commit message of patch;
* Fixed the stmmac_dma_operation_mode() method;
* Changed some code comments.

v12:
* The biggest change is the re-splitting of patches.
* Add a "gmac_version" in loongson_data, then we only
read it once in the _probe().
* Drop Serge's patch.
* Rebase to the latest code state.
* Fixed the gnet commit message.

* Break loongson_phylink_get_caps(), fix bad logic.
* Remove a unnecessary ";".
* Remove some unnecessary "{}".
* add a blank.
* Move the code of fix _force_1000 to patch 6/6.

The main changes occur in these two functions:
loongson_dwmac_probe();
loongson_dwmac_setup();

v10:

* Add a #define for Port Select.

others:

* Drop patch 3/6, we need mac_interface.
* Adjusted the code layout of gnet patch.
* Corrected several errata in commit message.
* Move DISABLE_FORCE flag to loongson_gnet_data().

v9:
We have not provided a detailed list of equipment for a long time,
and I apologize for this. During this period, I have collected some
information and now present it to you, hoping to alleviate the pressure
of review.

1. IP core
We now have two types of IP cores, one is 0x37, similar to dwmac1000;
The other is 0x10. Compared to 0x37, we split several DMA registers
from one to two, and it is not worth adding a new entry for this.
According to Serge's comment, we made these devices work by overwriting
priv->synopsys_id = 0x37 and mac->dma = <LS_dma_ops>.

1.1. Some more detailed information
The number of DMA channels for 0x37 is 1; The number of DMA channels
for 0x10 is 8. Except for channel 0, otherchannels do not support
sending hardware checksums. Supported AV features are Qav, Qat, and Qas,
and the rest are consistent with 3.73.

2. DEVICE
We have two types of devices,
one is GMAC, which only has a MAC chip inside and needs an external PHY
chip;
the other is GNET, which integrates both MAC and PHY chips inside.

2.1. Some more detailed information
GMAC device: LS7A1000, LS2K1000, these devices do not support any pause
mode.
gnet device: LS7A2000, LS2K2000, the chip connection between the mac and
phy of these devices is not normal and requires two rounds of
negotiation; LS7A2000 does not support half-duplex and
multi-channel;
to enable multi-channel on LS2K2000, you need to turn off
hardware checksum.
**Note**: Only the LS2K2000's IP core is 0x10, while the IP cores of other
devices are 0x37.

3. TABLE

device type pci_id ip_core
ls7a1000 gmac 7a03 0x35/0x37
ls2k1000 gmac 7a03 0x35/0x37
ls7a2000 gnet 7a13 0x37
ls2k2000 gnet 7a13 0x10
-----------------------------------------------
Changes:

* passed the CI
<https://github.com/linux-netdev/nipa/blob/main/tests/patch/checkpatch
/checkpatch.sh>
* reverse xmas tree order.
* Silence build warning.
* Re-split the patch.
* Add more detailed commit message.
* Add more code comment.
* Reduce modification of generic code.
* using the GNET-specific prefix.
* define a new macro for the GNET MAC.
* Use an easier way to overwrite mac.
* Removed some useless printk.

v8:
* The biggest change is according to Serge's comment in the previous
edition:
Seeing the patch in the current state would overcomplicate the generic
code and the only functions you need to update are
dwmac_dma_interrupt()
dwmac1000_dma_init_channel()
you can have these methods re-defined with all the Loongson GNET
specifics in the low-level platform driver (dwmac-loongson.c). After
that you can just override the mac_device_info.dma pointer with a
fixed stmmac_dma_ops descriptor. Here is what should be done for that:

1. Keep the Patch 4/9 with my comments fixed. First it will be partly
useful for your GNET device. Second in general it's a correct
implementation of the normal DW GMAC v3.x multi-channels feature and
will be useful for the DW GMACs with that feature enabled.

2. Create the Loongson GNET-specific
stmmac_dma_ops.dma_interrupt()
stmmac_dma_ops.init_chan()
methods in the dwmac-loongson.c driver. Don't forget to move all the
Loongson-specific macros from dwmac_dma.h to dwmac-loongson.c.

3. Create a Loongson GNET-specific platform setup method with the next
semantics:
+ allocate stmmac_dma_ops instance and initialize it with
dwmac1000_dma_ops.
+ override the stmmac_dma_ops.{dma_interrupt, init_chan} with
the pointers to the methods defined in 2.
+ allocate mac_device_info instance and initialize the
mac_device_info.dma field with a pointer to the new
stmmac_dma_ops instance.
+ call dwmac1000_setup() or initialize mac_device_info in a way
it's done in dwmac1000_setup() (the later might be better so you
wouldn't need to export the dwmac1000_setup() function).
+ override stmmac_priv.synopsys_id with a correct value.

4. Initialize plat_stmmacenet_data.setup() with the pointer to the
method created in 3.

* Others:
Re-split the patch.
Passed checkpatch.pl test.

v7:
* Refer to andrew's suggestion:
- Add DMA_INTR_ENA_NIE_RX and DMA_INTR_ENA_NIE_TX #define's, etc.

* Others:
- Using --subject-prefix="PATCH net-next vN" to indicate that the
patches are for the networking tree.
- Rebase to the latest networking tree:
<git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git>

v6:

* Refer to Serge's suggestion:
- Add new platform feature flag:
include/linux/stmmac.h:
+#define STMMAC_FLAG_HAS_LGMAC BIT(13)

- Add the IRQs macros specific to the Loongson Multi-channels GMAC:
drivers/net/ethernet/stmicro/stmmac/dwmac_dma.h:
+#define DMA_INTR_ENA_NIE_LOONGSON 0x00060000 /* ...*/
#define DMA_INTR_ENA_NIE 0x00010000 /* Normal Summary */
...

- Drop all of redundant changes that don't require the
prototypes being converted to accepting the stmmac_priv
pointer.

* Refer to andrew's suggestion:
- Drop white space changes.
- break patch up into lots of smaller parts.
Some small patches have been put into another series as a preparation

*note* : This series of patches relies on the three small patches above.
* others
- Drop irq_flags changes.
- Changed patch order.

v4 -> v5:

* Remove an ugly and useless patch (fix channel number).
* Remove the non-standard dma64 driver code, and also remove
the HWIF entries, since the associated custom callbacks no
longer exist.
* Refer to Serge's suggestion: Update the dwmac1000_dma.c to
support the multi-DMA-channels controller setup.

See:
v4: <https://lore.kernel.org/loongarch/cover.1692696115.git.chenfeiyang@loongson.cn/>
v3: <https://lore.kernel.org/loongarch/cover.1691047285.git.chenfeiyang@loongson.cn/>

net: stmmac: Export dwmac1000_dma_ops

Export the DW GMAC DMA-ops descriptor so one could be available in
the low-level platform drivers. It will be utilized to override some
callbacks in order to handle the LS2K2000 GNET device specifics. The
GNET controller support is being added in one of the following up
commits.

net: stmmac: Add multi-channel support

DW GMAC v3.73 can be equipped with the Audio Video (AV) feature which
enables transmission of time-sensitive traffic over bridged local area
networks (DWC Ethernet QoS Product). In that case there can be up to two
additional DMA-channels available with no Tx COE support (unless there is
vendor-specific IP-core alterations). Each channel is implemented as a
separate Control and Status register (CSR) for managing the transmit and
receive functions, descriptor handling, and interrupt handling.

Add the multi-channels DW GMAC controllers support just by making sure the
already implemented DMA-configs are performed on the per-channel basis.

Note the only currently known instance of the multi-channel DW GMAC
IP-core is the LS2K2000 GNET controller, which has been released with the
vendor-specific feature extension of having eight DMA-channels. The device
support will be added in one of the following up commits.

net: stmmac: Move the atds flag to the stmmac_dma_cfg structure

ATDS (Alternate Descriptor Size) is a part of the DMA Bus Mode configs
(together with PBL, ALL, EME, etc) of the DW GMAC controllers. Seeing
it's not changed at runtime but is activated as long as the IP-core
has it supported (at least due to the Type 2 Full Checksum Offload
Engine feature), move the respective parameter from the
stmmac_dma_ops::init() callback argument to the stmmac_dma_cfg
structure, which already have the rest of the DMA-related configs
defined.

Besides the being added in the next commit DW GMAC multi-channels
support will require to add the stmmac_dma_ops::init_chan() callback
and have the ATDS flag set/cleared for each channel in there. Having
the atds-flag in the stmmac_dma_cfg structure will make the parameter
accessible from stmmac_dma_ops::init_chan() callback too.
