Merge remote-tracking branch 'remotes/awilliam/tags/vfio-updates-20190221.0' into staging (2019-02-22 15:48:04 +0000) are available in the Git repository at: https://github.com/berrange/qemu tags/authz-core-pull-request for you to fetch changes up to cfde05c6c0db7d3122a5491d50f62f7910ab8abb: authz: delete existing ACL implementation (2019-02-25 12:28:25 +0000) ---------------------------------------------------------------- Add a standard authorization framework The current network services now support encryption via TLS and in some cases support authentication via SASL. In cases where SASL is not available, x509 client certificates can be used as a crude authorization scheme, but using a sub-CA and controlling who you give certs to. In general this is not very flexible though, so this series introduces a new standard authorization framework. It comes with four initial authorization mechanisms - Simple - an exact username match. This is useful when there is exactly one user that is known to connect. For example when live migrating from one QEMU to another with TLS, libvirt would use the simple scheme to whitelist the TLS cert of the source QEMU. - List - an full access control list, with optional regex matching. This is more flexible and is used to provide 100% backcompat with the existing HMP ACL commands. The caveat is that we can't create these via the CLI -object arg yet. - ListFile - the same as List, but with the rules stored in JSON format in an external file. This avoids the -object limitation while also allowing the admin to change list entries on the file. QEMU uses inotify to notice these changes and auto-reload the file contents. This is likely a good default choice for most network services, if the "simple" mechanism isn't sufficient. - PAM - delegate the username lookup to a PAM module, which opens the door to many options including things like SQL/LDAP lookups. ---------------------------------------------------------------- Daniel P.
