In the current codebase airoha_eth driver supports just a single

Enable the capability to create a net_device for each GDM port of the

====================
Some pktgen fixes/improvments (part II)
While taking a look at '[PATCH net] pktgen: Avoid out-of-range in
get_imix_entries' ([1]) and '[PATCH net v2] pktgen: Avoid out-of-bounds
access in get_imix_entries' ([2], [3]) and doing some tests and code review
I detected that the /proc/net/pktgen/... parsing logic does not honour the
user given buffer bounds (resulting in out-of-bounds access).
This can be observed e.g. by the following simple test (sometimes the
old/'longer' previous value is re-read from the buffer):
$ echo add_device lo@0 > /proc/net/pktgen/kpktgend_0
$ echo "min_pkt_size 12345" > /proc/net/pktgen/lo\@0 && grep min_pkt_size /proc/net/pktgen/lo\@0
Params: count 1000 min_pkt_size: 12345 max_pkt_size: 0
Result: OK: min_pkt_size=12345
$ echo -n "min_pkt_size 123" > /proc/net/pktgen/lo\@0 && grep min_pkt_size /proc/net/pktgen/lo\@0
Params: count 1000 min_pkt_size: 12345 max_pkt_size: 0
Result: OK: min_pkt_size=12345
$ echo "min_pkt_size 123" > /proc/net/pktgen/lo\@0 && grep min_pkt_size /proc/net/pktgen/lo\@0
Params: count 1000 min_pkt_size: 123 max_pkt_size: 0
Result: OK: min_pkt_size=123
So fix the out-of-bounds access (and some minor findings) and add a simple
proc_net_pktgen selftest...

Merge branch 'add-sock_kmemdup-helper'
Geliang Tang says:
====================
add sock_kmemdup helper
While developing MPTCP BPF path manager [1], I found it's useful to
add a new sock_kmemdup() helper.
My use case is this:
In mptcp_userspace_pm_append_new_local_addr() function (see patch 3
in this patchset), it uses sock_kmalloc() to allocate an address
entry "e", then immediately duplicate the input "entry" to it:
'''
e = sock_kmalloc(sk, sizeof(*e), GFP_ATOMIC);
if (!e) {
ret = -ENOMEM;
goto append_err;
}
*e = *entry;
'''
When I implemented MPTCP BPF path manager, I needed to implement a
code similar to this in BPF.
The kfunc sock_kmalloc() can be easily invoked in BPF to allocate
an entry "e", but the code "*e = *entry;" that assigns "entry" to
"e" is not easy to implemented.
I had to implement such a "copy entry" helper in BPF:
'''
static void mptcp_pm_copy_addr(struct mptcp_addr_info *dst,
struct mptcp_addr_info *src)
{
dst->id = src->id;
dst->family = src->family;
dst->port = src->port;
if (src->family == AF_INET) {
dst->addr.s_addr = src->addr.s_addr;
} else if (src->family == AF_INET6) {
dst->addr6.s6_addr32[0] = src->addr6.s6_addr32[0];
dst->addr6.s6_addr32[1] = src->addr6.s6_addr32[1];
dst->addr6.s6_addr32[2] = src->addr6.s6_addr32[2];
dst->addr6.s6_addr32[3] = src->addr6.s6_addr32[3];
}
}
static void mptcp_pm_copy_entry(struct mptcp_pm_addr_entry *dst,
struct mptcp_pm_addr_entry *src)
{
mptcp_pm_copy_addr(&dst->addr, &src->addr);
dst->flags = src->flags;
dst->ifindex = src->ifindex;
}
'''
And add "write permission" for BPF to each field of mptcp_pm_addr_entry:
'''
@@ static int bpf_mptcp_pm_btf_struct_access(struct bpf_verifier_log *log,
case offsetof(struct mptcp_pm_addr_entry, addr.port):
end = offsetofend(struct mptcp_pm_addr_entry, addr.port);
break;
#if IS_ENABLED(CONFIG_MPTCP_IPV6)
case offsetof(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[0]):
end = offsetofend(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[0]);
break;
case offsetof(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[1]):
end = offsetofend(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[1]);
break;
case offsetof(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[2]):
end = offsetofend(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[2]);
break;
case offsetof(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[3]):
end = offsetofend(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[3]);
break;
#else
case offsetof(struct mptcp_pm_addr_entry, addr.addr.s_addr):
end = offsetofend(struct mptcp_pm_addr_entry, addr.addr.s_addr);
break;
#endif
'''
But if there's a sock_kmemdup() helper, it will become much simpler,
only need to call kfunc sock_kmemdup() instead in BPF.
So this patchset adds this new helper and uses it in several places.

mptcp: use sock_kmemdup for address entry
Instead of using sock_kmalloc() to allocate an address
entry "e" and then immediately duplicate the input "entry"
to it, the newly added sock_kmemdup() helper can be used in
mptcp_userspace_pm_append_new_local_addr() to simplify the code.
More importantly, the code "*e = *entry;" that assigns "entry"
to "e" is not easy to implemented in BPF if we use the same code
to implement an append_new_local_addr() helper of a BFP path
manager. This patch avoids this type of memory assignment
operation.

Merge branch 'net-stmmac-cleanup-transmit-clock-setting'
Russell King says:
====================
net: stmmac: cleanup transmit clock setting
A lot of stmmac platform code which sets the transmit clock is very
similar - they decode the speed to the clock rate (125, 25 or 2.5 MHz)
and then set a clock to that rate.
The DWMAC core appears to have a clock input for the transmit section
called clk_tx_i which requires this rate.
This series moves the code which sets this clock into the core stmmac
code.
Patch 1 adds a hook that platforms can use to configure the clock rate.
Patch 2 adds a generic implementation.
The remainder of the patches convert the glue code for various platforms
to use this new infrastructure.

net: stmmac: provide set_clk_tx_rate() hook
Several stmmac sub-drivers which support RGMII follow the same pattern.
They calculate the transmit clock rate, and then call clk_set_rate().
Analysis of several implementation documents suggests that the platform
is responsible for providing the transmit clock to the DWMAC core's
clk_tx_i. The expected rates are:
10Mbps 100Mbps 1Gbps
MII 2.5MHz 25MHz
RMII 2.5MHz 25MHz
GMII 125MHz
RGMI 2.5MHz 25MHz 125MHz
It seems some platforms require this clock to be manually configured,
but there are outputs from the MAC core that indicate the speed, so a
platform may use these to automatically configure the clock. Thus, we
can't just provide one solution to configure this clock rate.
Moreover, the clock may need to be derived from one of several sources
depending on the interface mode.
Provide a platform hook that is passed the transmit clock, interface
mode and speed.

- Setting napi_defer_hard_irqs to 1 to reduce the chance that GRO is

geneve: Allow users to specify source port range
Recently, in case of Cilium, we run into users on Azure who require to use
tunneling for east/west traffic due to hitting IPAM API limits for Kubernetes
Pods if they would have gone with publicly routable IPs for Pods. In case
of tunneling, Cilium supports the option of vxlan or geneve. In order to
RSS spread flows among remote CPUs both derive a source port hash via
udp_flow_src_port() which takes the inner packet's skb->hash into account.
For clusters with many nodes, this can then hit a new limitation [0]: Today,
the Azure networking stack supports 1M total flows (500k inbound and 500k
outbound) for a VM. [...] Once this limit is hit, other connections are
dropped. [...] Each flow is distinguished by a 5-tuple (protocol, local IP
address, remote IP address, local port, and remote port) information. [...]
For vxlan and geneve, this can create a massive amount of UDP flows which
then run into the limits if stale flows are not evicted fast enough. One
option to mitigate this for vxlan is to narrow the source port range via
IFLA_VXLAN_PORT_RANGE while still being able to benefit from RSS. However,
geneve currently does not have this option and it spreads traffic across
the full source port range of [1, USHRT_MAX]. To overcome this limitation
also for geneve, add an equivalent IFLA_GENEVE_PORT_RANGE setting for users.
Note that struct geneve_config before/after still remains at 2 cachelines
on x86-64. The low/high members of struct ifla_geneve_port_range (which is
uapi exposed) are of type __be16. While they would be perfectly fine to be
of __u16 type, the consensus was that it would be good to be consistent
with the existing struct ifla_vxlan_port_range from a uapi consumer PoV.

net/mlx5e: Avoid a hundred -Wflex-array-member-not-at-end warnings
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
So, in this particular case, we create a new `struct mlx5e_umr_wqe_hdr`
to enclose the header part of flexible structure `struct mlx5e_umr_wqe`.
This is, all the members except the flexible arrays `inline_mtts`,
`inline_klms` and `inline_ksms` in the anonymous union. We then replace
the header part with `struct mlx5e_umr_wqe_hdr hdr;` in `struct
mlx5e_umr_wqe`, and change the type of the object currently causing
trouble `umr_wqe` from `struct mlx5e_umr_wqe` to `struct
mlx5e_umr_wqe_hdr` --this last bit gets rid of the flex-array-in-the-middle
part and avoid the warnings.
Also, no new members should be added to `struct mlx5e_umr_wqe`, instead
any new members must be included in the header structure `struct
mlx5e_umr_wqe_hdr`. To enforce this, we use `static_assert()`, ensuring
that the memory layout of both the flexible structure and the newly
created header struct remain consistent.
The next step is to refactor the rest of the related code accordingly,
which means adding a bunch of `hdr.` wherever needed.
Lastly, we use `container_of()` whenever we need to retrieve a pointer
to the flexible structure `struct mlx5e_umr_wqe`.
So, with these changes, fix 125 of the following warnings:

selftests: drv-net: Check if combined-count exists
Some drivers, like tg3, do not set combined-count:
$ ethtool -l enp4s0f1
Channel parameters for enp4s0f1:
Pre-set maximums:
RX: 4
TX: 4
Other: n/a
Combined: n/a
Current hardware settings:
RX: 4
TX: 1
Other: n/a
Combined: n/a
In the case where combined-count is not set, the ethtool netlink code
in the kernel elides the value and the code in the test:
netnl.channels_get(...)
With a tg3 device, the returned dictionary looks like:
{'header': {'dev-index': 3, 'dev-name': 'enp4s0f1'},
'rx-max': 4,
'rx-count': 4,
'tx-max': 4,
'tx-count': 1}
Note that the key 'combined-count' is missing. As a result of this
missing key the test raises an exception:
# Exception| if channels['combined-count'] == 0:
# Exception| ~~~~~~~~^^^^^^^^^^^^^^^^^^
# Exception| KeyError: 'combined-count'
Change the test to check if 'combined-count' is a key in the dictionary
first and if not assume that this means the driver has separate RX and
TX queues.
With this change, the test now passes successfully on tg3 and mlx5
(which does have a 'combined-count').

net: ethernet: mtk_ppe_offload: Allow QinQ, double ETH_P_8021Q only
mtk_foe_entry_set_vlan() in mtk_ppe.c already supports double vlan
tagging, but mtk_flow_offload_replace() in mtk_ppe_offload.c only allows
for 1 vlan tag, optionally in combination with pppoe and dsa tags.
However, mtk_foe_entry_set_vlan() only allows for setting the vlan id.
The protocol cannot be set, it is always ETH_P_8021Q, for inner and outer
tag. This patch adds QinQ support to mtk_flow_offload_replace(), only in
the case that both inner and outer tags are ETH_P_8021Q.
Only PPPoE-in-Q (as before) and Q-in-Q are allowed. A combination
of PPPoE and Q-in-Q is not allowed.

====================
fixes for seg6 and rpl lwtunnels on input
As a follow up to commit
92191dd10730 ("net: ipv6: fix dst ref loops in
rpl, seg6 and ioam6 lwtunnels"), we also need a conditional dst cache on
input for seg6_iptunnel and rpl_iptunnel to prevent dst ref loops (i.e.,
if the packet destination did not change, we may end up recording a
reference to the lwtunnel in its own cache, and the lwtunnel state will
never be freed). This series provides a fix to respectively prevent a
dst ref loop on input in seg6_iptunnel and rpl_iptunnel.
