Comment 6 Chris Wilson 2019-01-11 19:01:16 UTC
Fwiw, it's a nasty bug (stray write) that could cause a lot of hard to diagnose issues in any test. It's definitely a use-after-free of some skb/pkt, so reporting to netdev?
Comment 7 Francesco Balestrieri 2019-04-11 07:57:15 UTC

Are you sure it is notourbug?
Comment 10 Chris Wilson 2019-08-29 19:23:42 UTC
The first one is very clear a use-after-free of the skb by the usbnet driver (if you want you can dig out the previous unresolved usbnet use-after-free bug). The last one has a similar struct written into the freed buffer, so likely to be the same culprit.
