Hi

I'm running OpenVPN 2.6.8 with DCO and a openvpn3.8.3 iOS client. I have the problem, that sometimes after a TLS renegotiation, the old connection remains active in OpenVPN server, which leads to several dead entries over time in status info. Once it even locked the whole server up after about 50 dead entries. It's difficult to reproduce but it can be done, it happens maybe every 30th time or so. If I use "reneg-sec 0" on server and client it doesn't happen, also if I set disable-dco. I set "reneg-sec 15" for testing.

I think the connection gets "stuck" when that netlink error comes up, but I'm not 100% sure. Also the client reconnects fine and still works. And it doesn't matter if IPv4 or IPv6, happens on both.

Hi @SwizzAppz and thanks for the report! Can you share the status output with the "dead entries" too?
And does the error above happen multiple times (i.e. on the next renegotiation)? or is this one off and then the connection is stuck?

The error can happen multiple times per client/connection. Though the last/newest connection still works normally then. As far as I remember, it also didn't look strange in status info, it's just several connections with the same IP and the bytes counter of the "dead" connections don't change.

I will share the status log as soon as it happens again, as I have to enable it first.

I just happened again, right after that netlink error. This is how management status info looks:

This is a dead connection. I'll try to reproduce it again with enabled status.log.
EDIT: Seems that status.log shows exactly the same.

This is another example on another server, where reneg-sec is not set on the client (default 3600). The first connection is the dead one:

Any news on this? It happened again, with just 1 (the same) client connected. Things I observed: The load is extremely high (ranging from 3.xx to 9.xx), but idle is at 99.x%. I can't stop nor kill the openvpn processes, also a soft reboot fails, I have to reboot the VM from KVM.

@SwizzAppz when you try soft rebooting and the reboot hangs, can you please run dmesg and see if there is any dco related output there?
The status log is just a symptom of some other misbehaviour, therefore there is not much to learn from there.
When the "dead connection" behaviour happens, do you always see that netlink error in the openvpn log?

BTW: It has nothing to do with TLS renegotiation, the issue happens even with reneg-sec 0 (client and server side) or with default settings, it just takes longer till it happens.

Thanks a lot.
A least this tells us where the issue is happening now

Any news on this issue? OpenVPN without DCO is really slow.

Hi

I just noticed a new ovpn-dco-v2 version (20240320). Are there any related fixes in that build I could test?

Thanks

hi @SwizzAppz sorry but there is no fix for this issue. ovpn-dco is undergoing a major restructuring as it was sent tot he kernel mailing list for review.

I expect any bug fixing to happen after that (if bugs are still there after the restructuring of course)

Using the default(?) value of keepalive (10 60) seems to have fixed the issue, no more crashes since 1 week.

@ordex I have the same problem here. What I noticed in the SourceCode is that in ovpn_peer_delete_work() the ovpn_peer_release(peer) is executed before ovpn_netlink_notify_del_peer(peer):

yeah, the idea was to stop i/o for that peer before notifying userspace. However, the peer should not be free'd until the next RCU period.
However, it's hard to say what is set to NULL in ovpn_netlink_notify_del_peer() that is causing the crash.

Do you have a reliable way to reproduce the issue?

(also please note that this part of the code is being totally rewritten, therefore it's likely that any bug existing in this code won't exist any more)

Yeah I found some other related issues here but I also didn't get any further. For now I have implemented these (dirty) hacks, since I don't want to disable DCO as it's really a big improvement:

  • Raised reneg-sec on server and disabled on client
  • Using default keepalive of 10 60
  • Monitoring for 'NULL' in dmesg and forcing a reboot
  • Monitoring for cpu load over 1.0 (multiply by cpu cores) and forcing a reboot
  • Daily rebooting the server

That why I can run it "stable" without any major downtimes (reboots luckily only take about 20 seconds).
Hope a stable version or kernel integrated module or however it's called of OpenVPN-DCO will get released soon.

Wouldn't we need an rcu_read_lock() in the ovpn_netlink_notify_del_peer() function?

Technically yes, however, this is not the right thing to do.
We should definitely invoke call_rcu when we are sure to be done with everything (as per your original suggestion).
What I am alluding to is the fact that it's still pretty hard that the RCU callback is truly executed before ovpn_netlink_notify_del_peer() is done.

This said, it's not clear to me what is becoming NULL. I'd rather expect peer to become garbage memory (if truly released), but not NULL.

Anyway, this part is being rewritten, therefore I don't think it makes much sense for me to spend time on it.

Any news on the rewriting and integrating in kernel? Is there any status progress / road map one can look up?

BTW, I got another error when this issue happens in dmesg: list_del corruption
Unfortunately I didn't save the dmesg output, but maybe it helps

You can monitor the netdev mailing list and look up for mails with "ovpn" in the subject.
Next week we expect version 6 of the patchset to go out.
Code is undergoing thorough review since a while and it takes a while because the code base is not small...

Not really because lists have also been rearranged/reworked big times.

Thanks for poking around though.
