Hi!
I noticed that nf_conntrack leaks kernel addresses, it uses the memory address
as identifier used for generating conntrack and expect ids..
Since these ids are also visible to unprivileged users via network namespaces
I suggest reverting these commits:
commit 7f85f914721ffcef382a57995182916bd43d8a65
Author: Patrick McHardy <kaber@xxxxxxxxx>

[NETFILTER]: nf_conntrack: kill unique ID
Remove the per-conntrack ID, its not necessary anymore for dumping.
For compatiblity reasons we send the address of the conntrack to
userspace as ID.

commit 3583240249ef354760e04ae49bd7b462a638f40c
Author: Patrick McHardy <kaber@xxxxxxxxx>

[NETFILTER]: nf_conntrack_expect: kill unique ID
Similar to the conntrack ID, the per-expectation ID is not needed
anymore, kill it.
