Hi Michael,
I tested out a newly created openvpn connection on Openssl-3.x and installed that on my laptop with the existing legacy providers lines in the openssl.cnf file commented out. that connection was successfully made.
So what we discussed is the case. Any new connection from CU175 onwards will work with a system with OpenSSL-3.x
It was what we hoped for and expected but it is good to have it confirmed.
Regards,
Adolf.

Thank you.
I just created a page to explain this problem:
https://wiki.ipfire.org/configuration/services/openvpn/openssl-3-transition
Please feel free to edit if I forgot to mention something.
We should include this in the change log for the release, but highlight that this breaking change has not been introduced in c175, but c175 has the fix.

Hi All,
I Have submitted a patch set for fixing the bug#13137 related to OpenVPN. This patch set together with the one for bug#13138 related to IPSec that I shipped yesterday fix the major bugs I found for CU175.
Sorry it took a bit longer than I had hoped for.
Please let me know if there are any problems with what I have produced and I will work to sort them out.
I am not aware of any other blocking bugs for CU175 at this point in time. :crossed_fingers:
Regards,
Adolf.

The poster found the following reference
https://serverfault.com/questions/857131/odd-error-while-using-openssl
which suggests that openssl can sometimes give spurious error messages if unique_subject is not explicitly defined as yes but it doesn't give any suggestion for why this would have occurred with the move to openssl-3.x

Hi All,
Just when you thought it was safe to get back in the water - aaaaah.
I suspected that IPSec would also suffer from the same problem of openssl-3.x vs openssl-1.1.1x for the opening of .p12 certificates.
Today, from feedback from Roberto Pena in the forum, it turns out that trying to create a Root/Host certificate set for IPSec causes an error message to be created.
I reproduced this on CU175 Testing build master/9797af30 and confirmed that it did not happen in CU174.
I added the -legacy option into every openssl command in vpnmain.cgi dealing with .p12 files but this did not solve this problem. I then added -legacy to every openssl command. This solved the problem.
Someone else in that thread about the IPSec Root/Host certificate creation has suggested adding
"unique_subject = yes"
into /var/ipfire/certs/index.txt.attr
have tried that and it does solve the problem.
However now have the dilemma of which solution to use, the unique_subject or the legacy option in the openssl commands.
I have asked the person who suggested the unique_subject fix, why this is the correct fix to this problem. I searched on the internet but only found comments that the default value of that variable is yes anyway and no reference to it needing to be changed because of a changed from openssl-1.1.1x to openssl-3.x
I will see what input the poster provides but does anyone on this mailing list have any suggestion as to how the unique_subject = yes fix works and why it is needed with openssl-3.x or any input on how to make the decision between the two approaches or if both should be used?
Regards,
Adolf.
I then tried only adding the legacy option to each non .p12 openssl command one at a time but this also did not fix the problem. So more than one of the non .p12 commands needs to be defined as legacy at the same time.
I thought if every openssl command was going to have the legacy option then the same effect should be possible by adding the legacy provider into the openssl.cnf file. Tried this but it didn't solve the error message when creating the Root/Host IPSec certificate set. So there must be some sort of difference between the command line legacy option and the legacy provider option in the openssl.cnf file.
So I will also submit a patch set for the vpnmain.cgi file where all openssl commands have the legacy option added.
The same will be done for the ovpnmain.cgi file to be on the safe side. Currently I had only added it to the openssl commands running on .p12 files.
I did test creating the Root/Host certificate set on OpenVPN with openssl-3.x and that worked successfully but I think having the legacy option on every openssl command should not cause anything to break.
Hope to provide a patch set for the various IPSec/OpenVPN openssl issues found over the weekend, presuming no one finds any further issues. As Michael has said in the past. Better to get any patch fix correct than to have a faulty one quickly.
Regards,
Adolf.

The failure I found has no openssl command in the cgi file and adding "providers legacy default" to the end of the client n2n conf file made everything work again.
Your idea of making a modification to the openssl conf file is a good one and I will try that out and see if that works. If so then that would be the better approach as then any certificates would be covered by the legacy approach if required.
