[Bug 474] New: nf_conntrack marks all packets as INVALID on sparc64 (probably endianness bug)
https://bugzilla.netfilter.org/bugzilla/show_bug.cgi?id=474
           Summary: nf_conntrack marks all packets as INVALID on sparc64
                    (probably endianness bug)
           Product: netfilter/iptables
           Version: linux-2.6.x
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: nf_conntrack
        AssignedTo: yasuyuki.kozakai@toshiba.co.jp
        ReportedBy: jan.oravec@6com.sk
I have new connection tracking engine in kernel 2.6.16 -- nf_conntrack -- and
the following rules in IPv4 iptables INPUT table:
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -m state --state INVALID -j DROP
All INPUT packet are dropped on the INVALID rule. (e.g. icmp echo request/reply,
...)
The machine is sparc64 running 64-bit kernel. I think that the problem is
related to big endianness, because I haven't observed it on other
architectures
(amd64, x86).
The nf_conntrack is loaded into kernel as module.
