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

From: Elena Reshetova
Date: Thu Mar 16 2017 - 14:26:06 EST


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.
