[PATCH 00/15] networking drivers refcount_t conversions

From: Elena Reshetova
Date: Fri Oct 20 2017 - 03:24:08 EST


Note: these are the last patches related to networking that perform
conversion of refcounters from atomic_t to refcount_t.
In contrast to the core network refcounter conversions that
were merged earlier, these are much more straightforward ones.

This series, for various networking drivers, 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.
Patches are based on top of net-next.
If there are no objections to the patches, please merge them via respective trees
