I realize this has been merged to net-next already, but I'm getting a
use-after-free with KASAN in page_to_skb() with this patch. Reverting this
change fixes the UAF. I've included the KASAN dump below, and a couple of
comments inline.
I think something went wrong, this was merged before it was acked. Based on the
Jason Wang's comments, there are still some tests that have not been done?

If it has been merged, what should I do now, can I make up the test?


I think so, please test net-next which should contains the fixes from Eric.

Thanks




Thanks.
