AF_XDP bug

AF_XDP bug

[Joseph Vance Reilly]

Hello,

My name is Joseph Reilly and I recently created a bug report on the bugzilla page for the linux kernel. This is a bug that causes an IO_PAGEFAULT when receiving high amounts of traffic on an interface running an XDP program. This problem has been observed with a Mellanox networking card and AMD CPU but may also be present in more configurations. The bugzilla report is here: https://bugzilla.kernel.org/show_bug.cgi?id=217712

For reference, the bug is #217712 in the networking product listed under the component "other"

Best,
Joseph Reilly

If you'd like to forward your BZ report to the mailing lists:

* Quote the whole starting thread and on the forward mail, add pointer to
  your attached files on BZ
* Add relevant subsystems and maintainers to recipient list. See MAINTAINERS
  on the root of kernel tree or run `scripts/get_maintainer.pl` script.
  This is important; otherwise you won't get any helpful responses.

I had forwarded your report on [1] as an example.

Thanks.
