Hi,
The following patch should be backported to the stable kernel versions
starting from 5.10
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=60240bc26114
The patch fixes inheriting the need_wakeup flag for AF_XDP sockets.
Sockets with XDP_SHARED_UMEM cannot have good performance because they
do not get this flag from the first socket.
Fixes: b5aea28dca134 ("xsk: Add shared umem support between queue ids")
Commit ID: 60240bc26114 ("xsk: Inherit need_wakeup flag for shared sockets")
Kernels: 5.10 - 5.15 - 5.19 - 6.0
Best Regards,
Jalal
