Revision db61ecc3352d72513c1b07805bd6f760e30c001b authored by Tommy S. Christensen on 19 May 2005, 19:46:59 UTC, committed by David S. Miller on 19 May 2005, 19:46:59 UTC
This bug causes: assertion (!atomic_read(&sk->sk_rmem_alloc)) failed at net/netlink/af_netlink.c (122) What's happening is that: 1) The skb is sent to socket 1. 2) Someone does a recvmsg on socket 1 and drops the ref on the skb. Note that the rmalloc is not returned at this point since the skb is still referenced. 3) The same skb is now sent to socket 2. This version of the fix resurrects the skb_orphan call that was moved out, last time we had 'shared-skb troubles'. It is practically a no-op in the common case, but still prevents the possible race with recvmsg. Signed-off-by: Tommy S.
