[PATCH net-next 0/2] tcp: take care of another syzbot issue

[Eric Dumazet <eric.dumazet@gmail.com>]

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.

Eric Dumazet (2):
  net: add skb_set_end_offset() helper
  net: preserve skb_end_offset() in skb_unclone_keeptruesize()
