Hello,
this series tries to fix a long standing problem in the CAN echo SKB
handling. The problem shows up if an echo SKB for a SKB that references
an already closed socket is created.
It looks like the mac80211/tx.c has the same problem, see RFC patch 3
for details.
regards,
Oleksij

skbuff: skb_clone_sk_optional(): add function to always clone a skb
and increase refcount on sk if valid
can: fix ref count warning if socket was closed before skb was cloned
[RFC] mac80211: ieee80211_store_ack_skb(): make use of
skb_clone_sk_optional()
