[SRU] [hardy] openvpn multihome issue (64bit)

[persson]

Binary package hint: openvpn

openvpn 2.1~rc7-1ubuntu3.5 seems to suffer from this bug:

http://article.gmane.org/gmane.network.openvpn.devel/2227

or at least I'm not able to get the "multihome" working. Clients just hang and in the server log lots of messages like this appear:

write UDPv4 []: Invalid argument (code=22)

Info about the system:

# lsb_release -rd
Description: Ubuntu 8.04.3 LTS
Release: 8.04

Let me know if more information is needed.

Thanks Ill take the fix from the openvpn SVN mentioned in the thread.

This is already fixed in karmic. It might be a good candidate for an SRU.

[persson (persson)]

yeah, unfortunately this is aproduction box that cannot be upgraded for now, so it would be great to have it in hardy as well. Thanks.

Statement of Impact:

Openvpn in hardy shipped a bug that prevented users on amd64 machines to use the mulihome option. It causes the client to hang and not function properly.

How this has been addressed:

This bug has been fixed upstream and is fixed in Karmic. I have attached the bug that fixes this probem.

How to reproduce:

1. Install an openvpn server and client with multihomed support. (Best done in kvm)

There should be no regressions with this patch.

If you have any questions please let me know.

Hi Persson,

Would you be availble to do some testing for this fix in hardy?

Thanks
chuck

[persson (persson)]

Yes sure no problem.

[Martin Pitt (pitti)]

How does this affect all other architectures? It's not quite obvious what the #pragma pack does. To be on the safe side, could this perhaps be included in an #ifdef which only matches on amd64?

[Martin Pitt (pitti)]

Chuck, ping?

[Chuck Short (zulcss)]

Sorry havent got a chance to address this yet.

Regards
chuck

I took the previous patch and surrounded the pragma with #ifdef __x86_64 and #endif. I did a compile test on a 64bit Lucid host.

[Martin Pitt (pitti)]

Thanks Simon!

[Imre Gergely (cemc)]

I would like to help solve this. Is there anything to test maybe?

Hardy has seen the end of its life and is no longer receiving any updates. Marking the Hardy task for this ticket as "Won't Fix".
