  "message": "[DCCP]: Fix skb-\u003ecb conflicts with IP\n\ndev_queue_xmit() and the other IP output functions expect to get a skb\nwith clear or properly initialized skb-\u003ecb. Unlike TCP and UDP, the\ndccp_skb_cb doesn\u0027t contain a struct inet_skb_parm at the beginning,\nso the DCCP-specific data is interpreted by the IP output functions.\nThis can cause false negatives for the conditional POST_ROUTING hook\ninvocation, making the packet bypass the hook.\n\nAdd a inet_skb_parm/inet6_skb_parm union to the beginning of\ndccp_skb_cb to avoid clashes. Also add a BUILD_BUG_ON to make\nsure it fits in the cb.\n\n[ Combined with patch from Gerrit Renker to remove two now unnecessary\n  memsets of IPCB(skb)-\u003eopt ]\n\nSigned-off-by: Patrick McHardy \u003ckaber@trash.net\u003e\nAcked-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nSigned-off-by: David S.
