I'm announcing the release of the 6.9.5 kernel.
All users of the 6.9 kernel series must upgrade.
The updated 6.9.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.9.y
and can be browsed at the normal kernel.org git web browser:
https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h

sxdp_shared_umem_fd field as you registered the UMEM on that
socket. These two sockets will now share one and the same UMEM.
-In this case, it is possible to use the NIC's packet steering

+In libbpf, you need to use the xsk_socket__create_shared() API as it

+function for all the sockets you create, or you can use it for the
+second and following ones and use xsk_socket__create() for the first
+one. Both methods yield the same result.
Note that a UMEM can be shared between sockets on the same queue id
and device, as well as between queues on the same device and between
-devices at the same time. It is also possible to redirect to any
-socket as long as it is bound to the same umem with XDP_SHARED_UMEM.
