+Subject: [PATCH] dccp: fix freeing skb too early for IPV6_RECVPKTINFO
+
+In the current DCCP implementation an skb for a DCCP_PKT_REQUEST packet
+is forcibly freed via __kfree_skb in dccp_rcv_state_process if
+dccp_v6_conn_request successfully returns.
+
+However, if IPV6_RECVPKTINFO is set on a socket, the address of the skb
+is saved to ireq->pktopts and the ref count for skb is incremented in
+dccp_v6_conn_request, so skb is still in use. Nevertheless, it gets freed
+in dccp_rcv_state_process.
+
+Fix by calling consume_skb instead of doing goto discard and therefore
+calling __kfree_skb.
+
+Similar fixes for TCP:
+
+fb7e2399ec17f1004c0e0ccfd17439f8759ede01 [TCP]: skb is unexpectedly freed.
+0aea76d35c9651d55bbaf746e7914e5f9ae5a25d tcp: SYN packets are now
+simply consumed

-Subject: [PATCH] x86/fpu: Fix invalid FPU ptrace state after execve()
-
-commit b22cbe404a9cc3c7949e380fa1861e31934c8978 upstream.
-
-Robert O'Callahan reported that after an execve PTRACE_GETREGSET
-NT_X86_XSTATE continues to return the pre-exec register values
-until the exec'ed task modifies FPU state.
-
-The test code is at:
-
-  https://bugzilla.redhat.com/attachment.cgi?id=1164286.
-
-What is happening is fpu__clear() does not properly clear fpstate.
-Fix it by doing just that.
