Subject[PATCH net v2 0/2] add support for skb with sk ref cloning
Date
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
