====================
mlx5-updates-2023-12-13
Preparation for mlx5e socket direct feature.
Socket direct will allow multiple PF devices attached to different
NUMA nodes but sharing the same physical port.
The following series is a small refactoring series in preparation
to support socket direct in the following submission.
Highlights:
- Define required device registers and bits related to socket direct
- Flow steering re-arrangements
- Generalize TX objects (TISs) and store them in a common object, will
be useful in the next series for per function object management.
- Decouple raw CQ objects from their parent netdev priv
- Prepare devcom for Socket Direct device group discovery.
Please see the individual patches for more information.

====================
Rust abstractions for network PHY drivers
No functional change since v10; only comment and commit log updates.
This patchset adds Rust abstractions for phylib. It doesn't fully
cover the C APIs yet but I think that it's already useful. I implement
two PHY drivers (Asix AX88772A PHYs and Realtek Generic FE-GE). Seems
they work well with real hardware.
The first patch introduces Rust bindings for phylib.
The second patch adds a macro to declare a kernel module for PHYs
drivers.
The third adds the Rust ETHERNET PHY LIBRARY entry to MAINTAINERS
file; adds the binding file and me as a maintainer (as Andrew Lunn
suggested) with Trevor Gross as a reviewer.
The last patch introduces the Rust version of Asix PHY driver,
drivers/net/phy/ax88796b.c. The features are equivalent to the C
version. You can choose C (by default) or Rust version on kernel
configuration.

This macro creates an array of kernel's `struct phy_driver` and
registers it. This also corresponds to the kernel's
`MODULE_DEVICE_TABLE` macro, which embeds the information for module
loading into the module binary file.
A PHY driver should use this macro.

This patch adds abstractions to implement network PHY drivers; the
driver registration and bindings for some of callback functions in
struct phy_driver and many genphy_ functions.
This feature is enabled with CONFIG_RUST_PHYLIB_ABSTRACTIONS=y.
This patch enables unstable const_maybe_uninit_zeroed feature for
kernel crate to enable unsafe code to handle a constant value with
uninitialized data. With the feature, the abstractions can initialize
a phy_driver structure with zero easily; instead of initializing all
the members by hand. It's supposed to be stable in the not so distant
future.

Currently a MDIO bus is created if the devicetree description is either:
1. Not fixed-link
2. fixed-link but contains a MDIO bus as well
The "1" case above isn't always accurate. If there's a phy-handle,
it could be referencing a phy on another MDIO controller's bus[1]. In
this case, where the MDIO bus is not described at all, currently
stmmac will make a MDIO bus and scan its address space to discover
phys (of which there are none). This process takes time scanning a bus
that is known to be empty, delaying time to complete probe.
There are also a lot of upstream devicetrees[2] that expect a MDIO bus
to be created, scanned for phys, and the first one found connected
to the MAC. This case can be inferred from the platform description by
not having a phy-handle && not being fixed-link. This hits case "1" in
the current driver's logic, and must be handled in any logic change here
since it is a valid legacy dt-binding.
Let's improve the logic to create a MDIO bus if either:
- Devicetree contains a MDIO bus
- !fixed-link && !phy-handle (legacy handling)
This way the case where no MDIO bus should be made is handled, as well
as retaining backwards compatibility with the valid cases.
Below devicetree snippets can be found that explain some of
the cases above more concretely.
Here's[0] a devicetree example where the MAC is both fixed-link and
driving a switch on MDIO (case "2" above). This needs a MDIO bus to
be created:
&fec1 {
phy-mode = "rmii";
fixed-link {
speed = <100>;
full-duplex;
};
mdio1: mdio {
switch0: switch0@0 {
compatible = "marvell,mv88e6190";
pinctrl-0 = <&pinctrl_gpio_switch0>;
};
};
};
Here's[1] an example where there is no MDIO bus or fixed-link for
the ethernet1 MAC, so no MDIO bus should be created since ethernet0
is the MDIO master for ethernet1's phy:
ðernet0 {
phy-mode = "sgmii";
phy-handle = <&sgmii_phy0>;
mdio {
compatible = "snps,dwmac-mdio";
sgmii_phy0: phy@8 {
compatible = "ethernet-phy-id0141.0dd4";
reg = <0x8>;
device_type = "ethernet-phy";
};
sgmii_phy1: phy@a {
compatible = "ethernet-phy-id0141.0dd4";
reg = <0xa>;
device_type = "ethernet-phy";
};
};
};
ðernet1 {
phy-mode = "sgmii";
phy-handle = <&sgmii_phy1>;
};
Finally there's descriptions like this[2] which don't describe the
MDIO bus but expect it to be created and the whole address space
scanned for a phy since there's no phy-handle or fixed-link described:
&gmac {
phy-supply = <&vcc_lan>;
phy-mode = "rmii";
snps,reset-gpio = <&gpio3 RK_PB4 GPIO_ACTIVE_HIGH>;
snps,reset-active-low;
snps,reset-delays-us = <0 10000 1000000>;
};

Since we never support this feature for I40E driver, we don't have to
display the value when using 'ethtool -c eth0'.
Before this patch applied, the rx-frames-irq is 256 which is consistent
with tx-frames-irq. Apparently it could mislead users.

MDIO mux cleanup
This small patch set resolves some technical debt in the MDIO mux driver
which was discovered during the investigation for commit 1f9f2143f24e
("net: mdio-mux: fix C45 access returning -EIO after API change").
The patches have been sitting for 2 months in the NXP SDK kernel and
haven't caused issues.

After the mii_bus API conversion to a split read() / read_c45(), there
might be MDIO parent buses which only populate the read_c45() and
write_c45() function pointers but not the C22 variants.
We haven't seen these in the wild paired with MDIO multiplexers, but
Andrew points out we should treat the corner case.

Showing the precise error symbols can help debugging probe issues, such
as the recent -EIO error in of_mdiobus_register() caused by the lack of

Driver has a logic leak in ring data allocation/free,
where aq_ring_free could be called multiple times on same ring,
if system is under stress and got memory allocation error.
Ring pointer was used as an indicator of failure, but this is
not correct since only ring data is allocated/deallocated.
Ring itself is an array member.
Changing ring allocation functions to return error code directly.
This simplifies error handling and eliminates aq_ring_free
on higher layer.

With a clock interval of 400 nsec and a 64 bit transactions (32 bit
preamble & 16 bit control & 16 bit data), it is reasonable to assume
the mdio transaction will take 25.6 usec. Add a 30 usec delay before
the first poll to reduce the chance of a 1000-2000 usec sleep.
Reduce the timeout from 1000ms to 100ms as it is unlikely for the bus
to take this long.

Jakub Kicinski says:
====================
tools: ynl-gen: fill in the gaps in support of legacy families
Fill in the gaps in YNL C code gen so that we can generate user
space code for all genetlink families for which we have specs.
The two major changes we need are support for fixed headers and
support for recursive nests.
For fixed header support - place the struct for the fixed header
directly in the request struct (and don't bother generating access
helpers). The member of a fixed header can't be too complex, and
also are by definition not optional so the user has to fill them in.
The YNL core needs a bit of a tweak to understand that the attrs
may now start at a fixed offset, which is not necessarily equal
to sizeof(struct genlmsghdr).
Dealing with nested sets is much harder. Previously we'd gen
the nested structs as:
struct outer {
struct inner inner;
};
If structs are recursive (e.g. inner contains outer again)
we must break this chain and allocate one of the structs
dynamically (store a pointer rather than full struct).

We avoid printing forward declarations and prototypes for most
types by sorting things topologically. But if structs nest we
do need the forward declarations, there's no other way.

To avoid infinite nesting store recursive structs by pointer.
If recursive struct is placed in the op directly - the first
instance can be stored by value. That makes the code much
less of a pain for majority of practical uses.

We try to keep the structures and helpers "topologically sorted",
to avoid forward declarations. When recursive nests are at play
we need to sort twice, because structs which end up being marked
as recursive will get a full set of forward declarations, so we
should ignore them for the purpose of sorting.

Track which nests are recursive. Non-recursive nesting gets
rendered in C as directly nested structs. For recursive
ones we need to put a pointer in, rather than full struct.

Currently, mvpp2 only supports RGMII. This commit adds support for MII.
The description in Marvell's functional specification seems to be wrong.
To enable MII, we need to set GENCONF_CTRL0_PORT3_RGMII, while for RGMII
we need to clear it. This is also how U-Boot handles it.

Driver has a logic leak in ring data allocation/free,
where double free may happen in aq_ring_free if system is under
stress and driver init/deinit is happening.
The probability is higher to get this during suspend/resume cycle.

stress -m 2000 --vm-bytes 20M --vm-hang 10 --backoff 1000
while true; do sudo ifconfig enp1s0 down; sudo ifconfig enp1s0 up; done

Because atalk_ioctl() accesses sk->sk_receive_queue
without holding a sk->sk_receive_queue.lock, it can
cause a race with atalk_recvmsg().
A use-after-free for skb occurs with the following flow.
```
atalk_ioctl() -> skb_peek()
atalk_recvmsg() -> skb_recv_datagram() -> skb_free_datagram()
```
Add sk->sk_receive_queue.lock to atalk_ioctl() to fix this issue.

Ahmed Zaki says:
====================
Support symmetric-xor RSS hash
Patches 1 and 2 modify the get/set_rxh ethtool API to take a pointer to
struct of parameters instead of individual params. This will allow future
changes to the uAPI-shared struct ethtool_rxfh without changing the
drivers' API.
Patch 3 adds the support at the Kernel level, allowing the user to set a
symmetric-xor RSS hash for a netdevice via:
# ethtool -X eth0 hfunc toeplitz symmetric-xor
and clears the flag via:
# ethtool -X eth0 hfunc toeplitz
The "symmetric-xor" is set in a new "input_xfrm" field in struct
ethtool_rxfh. Support for the new "symmetric-xor" flag will be later sent
to the "ethtool" user-space tool.
Patch 4 fixes a long standing bug with the ice hash function register
values. The bug has been benign for now since only (asymmetric) Toeplitz
hash (Zero) has been used.
Patches 5 and 6 lay some groundwork refactoring. While the first is
mainly cosmetic, the second is needed since there is no more room in the
previous 64-bit RSS profile ID for the symmetric attribute introduced in
the next patch.
Finally, patches 7 and 8 add the symmetric-xor support for the ice
(E800 PFs) and the iAVF drivers.
