changes v2: - drop mac80211 patch for now, it can go separately if needed
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
Oleksij Rempel (2): 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
