[Qemu-trivial] [PATCH 0/8] 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.
A later series that follows will integrate this framework into the VNC,
NBD, migration, and character device servers.
Daniel P. Berrangé (8):
util: add helper APIs for dealing with inotify
hw/usb: switch MTP to use new inotify APIs
authz: add QAuthZ object as an authorization base class
authz: add QAuthZSimple object type for trivial auth checks
authz: add QAuthZList object type for an access control list
authz: add QAuthZListFile object type for a file access control list
authz: add QAuthZPAM object type for authorizing using PAM
authz: delete existing ACL implementation
