Description Kapil Dakhane 2010-05-11 18:32:32 EDT
Description of problem:
The IPv6 transparency has already been implemented and Bytemobile has verified
that it works correctly. It is available at:

This was verified by running ip6tables command to set mangle rules:

ip6tables --table mangle --append PREROUTING --in-interface eth2.39 --protocol
tcp --destination ::0/0 --destination-port 0:65535 --jump TPROXY --tproxy-mark
0x1/0xFFFFFFFF --on-ip fdfd:6b2a:f17e::c0a8:2701 --on-port 4101
This gives following output:
ip6tables v1.4.6: unknown option `--tproxy-mark'
Try `ip6tables -h' or 'ip6tables --help' for more information.

FYI, We require this feature to claim that our product is IPv6 compliant. 

Version-Release number of selected component (if applicable):

How reproducible:
Happens everytime.

Steps to Reproduce:
1. Setup an ipv6 address for an interface
2. Issue above mentioned command

Actual results:

ip6tables v1.4.6: unknown option `--tproxy-mark'
Try `ip6tables -h' or 'ip6tables --help' for more information.

Expected results:
Command is accepted and IPv6 transparency works.

Additional info:
According to a reply on support Service Request # 2018648 :

07-MAY-2010 17:00:32  Ruban, Ranjith

I was able to see RFE filed to add tproxy to rhel 6 but currently the rhel 6
beta does not seem to have support for (v6) tproxy and the option --tproxy-mark
. Since rhel 6 beta is not a supported release would it be possible for you to
file a bugzilla regarding this case.

Hat Enterprise Linux Major release.  This request is not yet committed for
Comment 4 RHEL Product and Program Management 2010-07-15 10:18:51 EDT
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
Comment 5 Subhendu Ghosh 2010-07-16 13:07:48 EDT
Is the patch merged upstream?
Comment 6 Thomas Graf 2010-07-16 17:34:04 EDT
Yes, this is upstream.

Patch was merged in commit e84392707e10301b93121e1b74e2823db50cdf9e.
Comment 7 Subhendu Ghosh 2010-07-16 17:46:51 EDT
Thanks Thomas
Comment 9 Thomas Graf 2010-07-20 04:57:47 EDT
The RHEL6 kernel tree already includes the latest revision of TPROXY except for two minor cosmetic commits not affecting behaviour.

What is the status of the iptables package WRT tproxy?
Comment 10 Thomas Graf 2010-07-20 05:03:45 EDT
I just noticed that this RFE asks for IPv6 support in TPROXY exclusively which isn't even implemented upstream yet. I misread this assuming it only requested the upstream TPROXY code to be back ported.

I think we have to NACK this.
Comment 11 RHEL Product and Program Management 2010-07-20 17:34:37 EDT
Development Management has reviewed and declined this request.  You may appeal
this decision by reopening this request.
Comment 12 Subhendu Ghosh 2010-07-28 16:06:52 EDT
This request is being deferred to RHEL 6.1 pending inclusion of the Balabit patches referenced in Comment #0 in the upstream kernel.
Comment 13 Thomas Graf 2010-09-03 06:51:45 EDT
Upstream integration of this feature will be discussed at the netfilter summit in October 2010. Actual integration planned for November.
