Bug#540483: openvz: IPv6 netfilter not correctly virtualized



Package: linux-2.6
Version: 2.6.26-17lenny1
Severity: normal

This happens when I add -j LOG to the top of the INPUT and FORWARD
chains and ping the VE (2001:4b78:1:0200::1) from an external host:

Aug  8 12:28:06 web01 kernel: [70845.790963] IN=eth0 OUT=venet0 SRC=2001:1418:0001:0700:0000:0000:0000:000a DST=2001:4b78:0001:0200:0000:0000:0000:0001 LEN=104 TC=0 HOPLIMIT=59 FLOWLBL=0 PROTO=ICMPv6 TYPE=128 CODE=0 ID=11237 SEQ=1 

The same packet then *also* traverses the INPUT chain:

Aug  8 12:28:06 web01 kernel: [70845.790963] IN=venet0 OUT= MAC= SRC=2001:1418:0001:0700:0000:0000:0000:000a DST=2001:4b78:0001:0200:0000:0000:0000:0001 LEN=104 TC=0 HOPLIMIT=59 FLOWLBL=0 PROTO=ICMPv6 TYPE=128 CODE=0 ID=11237 SEQ=1 

Looks like the IPv6 packets entering the VE (where I have not configured
ip6tables) are incorrectly processed by the HN instead of the VE chains.
