Subject: [PATCH 0/9] net, ipv4, ipv6 refcounter conversions

This series, for ipv4/ipv6 components, replaces atomic_t reference
counters with the new refcount_t type and API (see include/linux/refcount.h).
By doing this we prevent intentional or accidental
underflows or overflows that can led to use-after-free vulnerabilities.

The patches are fully independent and can be cherry-picked separately.
If there are no objections to the patches, please merge them via respective trees.

Elena Reshetova (9):
  net, ipv6: convert ipv6_txoptions.refcnt from atomic_t to refcount_t
  net, ipv6: convert inet6_dev.refcnt from atomic_t to refcount_t
  net, ipv6: convert inet6_ifaddr.refcnt from atomic_t to refcount_t
  net, ipv6: convert ifmcaddr6.mca_refcnt from atomic_t to refcount_t
  net, ipv6: convert ifacaddr6.aca_refcnt from atomic_t to refcount_t
  net, ipv6: convert xfrm6_tunnel_spi.refcnt from atomic_t to refcount_t
  net, ipv6: convert ip6addrlbl_entry.refcnt from atomic_t to refcount_t
  net, ipv4: convert cipso_v4_doi.refcount from atomic_t to refcount_t
  net, ipv4: convert fib_info.fib_clntref from atomic_t to refcount_t
