	atomic_t variables are currently used to implement reference counters with the following properties: - counter is initialized to 1 using atomic_set() - a resource is freed upon counter reaching zero - once counter reaches zero, its further increments aren't allowed - counter schema uses basic atomic operations (set, inc, inc_not_zero, dec_and_test, etc.) Such atomic variables should be converted to a newly provided refcount_t type and API that prevents accidental counter overflows and underflows. This is important since overflows and underflows can lead to use-after-free situation and be exploitable. The variable clip_entry.refcnt is used as pure reference counter. Convert it to refcount_t and fix up the operations.

	Issue caught by 0-day kernel test infrastructure. Code changed to use sockaddr members so that %pISc can be used instead. Fixes: b5a02f503caa ('cxgb4 : Update ipv6 address handling api') Signed-off-by: Anish Bhatt <anish@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-01-15	cxgb4 : Update ipv6 address handling api	Anish Bhatt
	This patch improves on previously added support for ipv6 addresses. The code is consolidated to a single file and adds an api for use by dependent upper level drivers such as cxgb4i/iw_cxgb4 etc. Signed-off-by: Anish Bhatt <anish@chelsio.com> Signed-off-by: Deepak Singh <deepak.s@chelsio.com> Signed-off-by: David S.
