In order to support IP_PKTINFO on those packets, we need to call
ipv4_pktinfo_prepare.
When sending mrouted/pimd daemons a cache report IGMP msg, it is
unnecessary to set dst on the newly created skb.
It used to be necessary on older versions until
commit d826eb14ecef ("ipv4: PKTINFO doesnt need dst reference") which
changed the way IP_PKTINFO struct is been retrieved.
Changes from v1:
1. Undo changes in ipv4_pktinfo_prepare function. use it directly
and copy the control block.
Fixes: d826eb14ecef ("ipv4: PKTINFO doesnt need dst reference")

This patch allows to assign and poll more than one EQ on the same
msix index.
It is achieved by introducing a list of attached EQs in each IRQ context.
It also removes the existing msix_index map that tried to ensure that there
is only one EQ at each msix_index.
This patch exports symbols for creating EQs from other MANA kernel modules.

As per the existing implementation, there exists a race between finding
a multicast/mirror group entry and deleting that entry. The group lock
was taken and released independently by rvu_nix_mcast_find_grp_elem()
function. Which is incorrect and group lock should be taken during the
entire operation of group updation/deletion. This patch fixes the same.

====================
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.

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>;
};

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.

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).

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

BPF FS mount options parsing follow ups
Original BPF token patch set ([0]) added delegate_xxx mount options which
supported only special "any" value and hexadecimal bitmask. This patch set
attempts to make specifying and inspecting these mount options more
human-friendly by supporting string constants matching corresponding bpf_cmd,
bpf_map_type, bpf_prog_type, and bpf_attach_type enumerators.
This implementation relies on BTF information to find all supported symbolic
names. If kernel wasn't built with BTF, BPF FS will still support "any" and
hex-based mask.

- strip BPF_, BPF_MAP_TYPE_, and BPF_PROG_TYPE_ prefixes,
do case-insensitive comparison, normalize to lower case (Alexei).

Besides already supported special "any" value and hex bit mask, support
string-based parsing of delegation masks based on exact enumerator
names. Utilize BTF information of `enum bpf_cmd`, `enum bpf_map_type`,
`enum bpf_prog_type`, and `enum bpf_attach_type` types to find supported
symbolic names (ignoring __MAX_xxx guard values and stripping repetitive
prefixes like BPF_ for cmd and attach types, BPF_MAP_TYPE_ for maps, and
BPF_PROG_TYPE_ for prog types). The case doesn't matter, but it is
normalized to lower case in mount option output. So "PROG_LOAD",
"prog_load", and "MAP_create" are all valid values to specify for
delegate_cmds options, "array" is among supported for map types, etc.
Besides supporting string values, we also support multiple values
specified at the same time, using colon (':') separator.
There are corresponding changes on bpf_show_options side to use known
values to print them in human-readable format, falling back to hex mask
printing, if there are any unrecognized bits. This shouldn't be
necessary when enum BTF information is present, but in general we should
always be able to fall back to this even if kernel was built without BTF.
As mentioned, emitted symbolic names are normalized to be all lower case.
Example below shows various ways to specify delegate_cmds options
through mount command and how mount options are printed back:
12/14 14:39:07.604
vmuser@archvm:~/local/linux/tools/testing/selftests/bpf

Add bpf_xdp_get_xfrm_state() kfunc
This patchset adds two kfunc helpers, bpf_xdp_get_xfrm_state() and
bpf_xdp_xfrm_state_release() that wrap xfrm_state_lookup() and
xfrm_state_put(). The intent is to support software RSS (via XDP) for
the ongoing/upcoming ipsec pcpu work [0]. Recent experiments performed
on (hopefully) reproducible AWS testbeds indicate that single tunnel
pcpu ipsec can reach line rate on 100G ENA nics.
Note this patchset only tests/shows generic xfrm_state access. The
"secret sauce" (if you can really even call it that) involves accessing
a soon-to-be-upstreamed pcpu_num field in xfrm_state. Early example is
available here [1].
