The old_flags variable is declared twice in __dev_change_flags(),
causing a shadow variable warning. This patch fixes the issue by
removing the redundant declaration, reusing the existing old_flags
variable instead.
net/core/dev.c:9225:16: warning: declaration shadows a local variable [-Wshadow]
9225 | unsigned int old_flags = dev->flags;

net/core/dev.c:9185:15: note: previous declaration is here
9185 | unsigned int old_flags = dev->flags;

1 warning generated.
Remove the redundant inner declaration and reuse the existing old_flags
variable since its value is not needed outside the if block, and it is
safe to reuse the variable. This eliminates the warning while
maintaining the same functionality.

Before this patch the NETDEV_XDP_ACT_NDO_XMIT XDP feature flag is set by
default as part of driver initialization, and is never cleared. However,
this flag differs from others in that it is used as an indicator for
whether the driver is ready to perform the ndo_xdp_xmit operation as
part of an XDP_REDIRECT. Kernel helpers
xdp_features_(set|clear)_redirect_target exist to convey this meaning.
This patch ensures that the netdev is only reported as a redirect target
when XDP queues exist to forward traffic.

Since commit under Fixes we set the window clamp in accordance
to newly measured rcvbuf scaling_ratio. If the scaling_ratio
decreased significantly we may put ourselves in a situation
where windows become smaller than rcvq_space, preventing
tcp_rcv_space_adjust() from increasing rcvbuf.
The significant decrease of scaling_ratio is far more likely
since commit 697a6c8cec ("tcp: increase the default TCP scaling ratio"),
which increased the "default" scaling ratio from ~30% to 50%.
Hitting the bad condition depends a lot on TCP tuning, and
drivers at play. One of Meta's workloads hits it reliably
under following conditions:
- default rcvbuf of 125k
- sender MTU 1500, receiver MTU 5000
- driver settles on scaling_ratio of 78 for the config above.
Initial rcvq_space gets calculated as TCP_INIT_CWND * tp->advmss
(10 * 5k = 50k). Once we find out the true scaling ratio and
MSS we clamp the windows to 38k. Triggering the condition also
depends on the message sequence of this workload. I can't repro
the problem with simple iperf or TCP_RR-style tests.

eth: mlx4: use the page pool for Rx buffers
Convert mlx4 to page pool. I've been sitting on these patches for
over a year, and Jonathan Lemon had a similar series years before.
We never deployed it or sent upstream because it didn't really show
much perf win under normal load (admittedly I think the real testing
was done before Ilias's work on recycling).
During the v6.9 kernel rollout Meta's CDN team noticed that machines
with CX3 Pro (mlx4) are prone to overloads (double digit % of CPU time
spent mapping buffers in the IOMMU). The problem does not occur with
modern NICs, so I dusted off this series and reportedly it still works.
And it makes the problem go away, no overloads, perf back in line with
older kernels. Something must have changed in IOMMU code, I guess.
This series is very simple, and can very likely be optimized further.
Thing is, I don't have access to any CX3 Pro NICs. They only exist
in CDN locations which haven't had a HW refresh for a while. So I can
say this series survives a week under traffic w/ XDP enabled, but
my ability to iterate and improve is a bit limited.

vxlan: Join / leave MC group when reconfigured
When a vxlan netdevice is brought up, if its default remote is a multicast
address, the device joins the indicated group.
Therefore when the multicast remote address changes, the device should
leave the current group and subscribe to the new one. Similarly when the
interface used for endpoint communication is changed in a situation when
multicast remote is configured. This is currently not done.
Both vxlan_igmp_join() and vxlan_igmp_leave() can however fail. So it is
possible that with such fix, the netdevice will end up in an inconsistent
situation where the old group is not joined anymore, but joining the
new group fails. Should we join the new group first, and leave the old one
second, we might end up in the opposite situation, where both groups are
joined. Undoing any of this during rollback is going to be similarly
problematic.
One solution would be to just forbid the change when the netdevice is up.
However in vnifilter mode, changing the group address is allowed, and these
problems are simply ignored (see vxlan_vni_update_group()):

instead, let's explore another approach: take a hint from
vsock_bpf_update_proto() and teach sockmap to accept only vsocks that are
already connected (no risk of transport being dropped or reassigned). At
the same time straight reject the listeners (vsock listening sockets do not
carry any transport anyway). This way BPF does not have to worry about

sockmap expects all vsocks to have a transport assigned, which is expressed
in vsock_proto::psock_update_sk_prot(). However, there is an edge case
where an unconnected (connectible) socket may lose its previously assigned
transport. This is handled with a NULL check in the vsock/BPF recv path.
Another design detail is that listening vsocks are not supposed to have any
transport assigned at all. Which implies they are not supported by the
sockmap. But this is complicated by the fact that a socket, before
switching to TCP_LISTEN, may have had some transport assigned during a
failed connect() attempt. Hence, we may end up with a listening vsock in a
sockmap, which blows up quickly:

This patch implements below changes,
1. To avoid concurrency with normal traffic uses
XDP queues.
2. Since there are chances that XDP and AF_XDP can
fall under same queue uses separate flags to handle
dma buffers.
