Subject: ipvs: uninitialized data with IP_VS_IPV6
From: Dan Carpenter <[email protected]>
commit 3b05ac3824ed9648c0d9c02d51d9b54e4e7e874f upstream.
The app_tcp_pkt_out() function expects "*diff" to be set and ends up
using uninitialized data if CONFIG_IP_VS_IPV6 is turned on.
The same issue is there in app_tcp_pkt_in(). Thanks to Julian Anastasov
for noticing that.
