From: Eric Dumazet <edumazet@google.com> This is a minor issue: It took months for syzbot to find a C repro, and even with it, I had to spend a lot of time to understand KFENCE was a prereq. With the default kfence 500ms interval, I had to be very patient to trigger the kernel warning and perform my analysis. This series targets net-next tree, because I added a new generic helper in the first patch, then fixed the issue in the second one. They can be backported once proven solid.
