[Bug 823] New: IPv6 NAT memory leaking
...un at gmail.com
Estimated Hours: 0.0
I tried IPv6 NAT and the system always crashes due to out-of-memory.
Here are my steps to reproduce:
[VM-a] ------------------- [VM-b]
fd00:1234::a/64 fd00:1234::b/64
* VM-a and VM-b are both virtualbox VMs (Arch Linux, kernel 3.9.3-1-ARCH,
x866_64, with 64M memory)
1. Add an IPv6 NAT rule on VM-b (even it is never matched):
(VM-b)# ip6tables -t nat -A POSTROUTING -s abcd::1 -j LOG
2. Ping with big packets from VM-a:
(VM-a)# for i in {1..5000}; do ping6 -s 2000 -c 1 fd00:1234::b; done
3. Check slabinfo at VM-b, the size of kmalloc-25...
