(1) Current security implementation in VxHS uses the SSL key and certificate files. Do you think we can achieve all the intended security goals if we pass these two files paths (and names?) from the command line? (2) If we are OK to continue with the present security scheme (using key and cert), then the only additional change needed might be to accept these files on the command line. (3) If we decide to rely on file permissions and SELinux policy to protect these key/cert files, then we don't need to pass the file names as a secret, instead, passing them as regular qemu_opt_get() options might be enough. Let us know what you think about the above? Thanks, Ashish

Yes, that's how other parts of QEMU deal with SSL NB, QEMU needs to pass 3 paths to libqnoio - the client cert, the client key, and the certificate authority certlist > (2) If we are OK to continue with the present security scheme (using > key and cert), then the only additional change needed might be to > accept these files on the command line. Yep, I think that's the minimum required change to make this mergable. > (3) If we decide to rely on file permissions and SELinux policy to > protect these key/cert files, then we don't need to pass the file > names as a secret, instead, passing them as regular qemu_opt_get() > options might be enough. That's correct - you can assume file permissions protect the cert files. I would expect the syntax to work as follows $QEMU -object tls-creds-x509,id=tls0,dir=/etc/pki/qemu/vxhs,endpoint=client \ -drive driver=vxhs,...other..opts...,tls-creds=tls0 When you see the 'tls-creds' flag, you can lookup the corresponding QCryptoTLSCredsX509 object and extract the 'dir' property from it. The include/crypto/tlscredsx509.h file has constants defined for the standard filenames - eg you would concatenate the directory with the constants QCRYPTO_TLS_CREDS_X509_CLIENT_KEY. This gives the filenames you can then pass to libqnio Regards, Daniel
