Subject: [PATCH net 0/3] net: start to replace copy_from_sockptr()

We got several syzbot reports about unsafe copy_from_sockptr()
calls. After fixing some of them, it appears that we could
use a new helper to factorize all the checks in one place.

This series targets net tree, we can later start converting
many call sites in net-next.

Eric Dumazet (3):
  net: add copy_safe_from_sockptr() helper
  mISDN: fix MISDN_TIME_STAMP handling
  nfc: llcp: fix nfc_llcp_setsockopt() unsafe copies
