The other thing I wonder about is why Tobias bisected this to
commit b838d5e1c5b6e57b10ec8af2268824041e3ea911
ipv4: mark DST_NOGC and remove the operation of dst_free()
from 'Jun 17 2017' and not to
commit 222d7dbd258dad4cd5241c43ef818141fad5a87a
net: prevent dst uses after free
from 'Sep 21 2017'.
Maybe Tobias has seen two bugs. Before
("net: prevent dst uses after free"), it was the
use after free, and after this fix it was a NULL
pointer derference of skb->dst.Uhm, yeah, I checked back, we actually had different bugs. My mistake, sorry for the confusion.
