[ovirt-users] Re: PKI Problem

Hi I did a fresh installation of version 4.4.0.3. After the engine setup I replaced the apache certificate with a custom certificate. I used this article to do it: https://myhomelab.gr/linux/2020/01/20/replacing_ovirt_ssl.html To summarize, I replaced those files with my own authority and the signed custom certificate /etc/pki/ovirt-engine/keys/apache.key.nopass /etc/pki/ovirt-engine/certs/apache.cer /etc/pki/ovirt-engine/apache-ca.pem That worked so far, apache uses now my certificate, login is possible. To setup a new machine, I need to upload an iso image, which failed. I found this error in /var/log/ovirt-imageio/daemon.log 2020-07-08 20:43:23,750 INFO (Thread-10) [http] OPEN client=192.168.1.228 2020-07-08 20:43:23,767 INFO (Thread-10) [backends.http] Open backend netloc='the_secret_hostname:54322' path='/images/ef60404c-dc69-4a3d-bfaa-8571f675f3e1' cafile='/etc/pki/ovirt-engine/apache-ca.pem' secure=True 2020-07-08 20:43:23,770 ERROR (Thread-10) [http] Server error Traceback (most recent call last): File "/usr/lib64/python3.6/site-packages/ovirt_imageio/_internal/http.py", line 699, in __call__ self.dispatch(req, resp) File "/usr/lib64/python3.6/site-packages/ovirt_imageio/_internal/http.py", line 744, in dispatch return method(req, resp, *match.groups()) File "/usr/lib64/python3.6/site-packages/ovirt_imageio/_internal/cors.py", line 84, in wrapper return func(self, req, resp, *args) File "/usr/lib64/python3.6/site-packages/ovirt_imageio/_internal/images.py", line 66, in put backends.get(req, ticket, self.config), File "/usr/lib64/python3.6/site-packages/ovirt_imageio/_internal/backends/__init__.py", line 53, in get cafile=config.tls.ca_file) File "/usr/lib64/python3.6/site-packages/ovirt_imageio/_internal/backends/http.py", line 48, in open secure=options.get("secure", True)) File "/usr/lib64/python3.6/site-packages/ovirt_imageio/_internal/backends/http.py", line 63, in __init__ options = self._options() File "/usr/lib64/python3.6/site-packages/ovirt_imageio/_internal/backends/http.py", line 364, in _options self._con.request("OPTIONS", self.url.path) File "/usr/lib64/python3.6/http/client.py", line 1254, in request self._send_request(method, url, body, headers, encode_chunked) File "/usr/lib64/python3.6/http/client.py", line 1300, in _send_request self.endheaders(body, encode_chunked=encode_chunked) File "/usr/lib64/python3.6/http/client.py", line 1249, in endheaders self._send_output(message_body, encode_chunked=encode_chunked) File "/usr/lib64/python3.6/http/client.py", line 1036, in _send_output self.send(msg) File "/usr/lib64/python3.6/http/client.py", line 974, in send self.connect() File "/usr/lib64/python3.6/http/client.py", line 1422, in connect server_hostname=server_hostname) File "/usr/lib64/python3.6/ssl.py", line 365, in wrap_socket _context=self, _session=session) File "/usr/lib64/python3.6/ssl.py", line 776, in __init__ self.do_handshake() File "/usr/lib64/python3.6/ssl.py", line 1036, in do_handshake self._sslobj.do_handshake() File "/usr/lib64/python3.6/ssl.py", line 648, in do_handshake self._sslobj.do_handshake() ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:897) 2020-07-08 20:43:23,770 INFO (Thread-10) [http] CLOSE client=192.168.1.228 [connection 1 ops, 0.019775 s] [dispatch 1 ops, 0.003114 s] I'm a python developer so I had no problem reading the traceback. The SSL handshake fails when image-io tries to connect to what I think is called an ovn-provider. But it is using my new authority certificate cafile='/etc/pki/ovirt-engine/apache-ca.pem' which does not validate the certificate generated by the ovirt engine setup, which the ovn-provider probably uses. I didn't exactly know where the parameter for the validation ca file is. Probably it is the ca_file parameter in /etc/ovirt-imageio/conf.d/50-engine.conf. But that needs to be set to my own authority ca file. I modified the python file to set the ca_file parameter to the engine setups ca_file directly /usr/lib64/python3.6/site-packages/ovirt_imageio/_internal/backends/__init__.py So the function call around line 50 looks like this: backend = module.open( ticket.url, mode, sparse=ticket.sparse, dirty=ticket.dirty, cafile='/etc/pki/ovirt-engine/ca.pem' #config.tls.ca_file ) Now the image upload works, but obviously this is not the way to fix things. Is there an other way to make image-io accept the certificate from the engine setup, while using my custom certificate? I don't want to replace the certificates of all ovirt components with custom certificates. I only need the weblogin with my custom certificate.
