/**
|
|
* QAuthZListFile:
|
|
*
|
|
* This authorization driver provides a file mechanism
|
|
* for granting access by matching user names against a
|
|
* file of globs. Each match rule has an associated policy
|
|
* and a catch all policy applies if no rule matches
|
|
*
|
|
* To create an instance of this class via QMP:
|
|
*
|
|
* {
|
|
* "execute": "object-add",
|
|
* "arguments": {
|
|
* "qom-type": "authz-list-file",
|
|
* "id": "authz0",
|
|
* "props": {
|
|
* "filename": "/etc/qemu/myvm-vnc.acl",
|
|
* "refresh": true
|
|
* }
|
|
* }
|
|
* }
|
|
*
|
|
* If 'refresh' is 'yes', inotify is used to monitor for changes
|
|
* to the file and auto-reload the rules.
|
|
*
|
|
* The myvm-vnc.acl file should contain the parameters for
|
|
* the QAuthZList object in JSON format:
|
|
*
|
|
* {
|
|
* "rules": [
|
|
* { "match": "fred", "policy": "allow", "format": "exact" },
|
|
* { "match": "bob", "policy": "allow", "format": "exact" },
|
|
* { "match": "danb", "policy": "deny", "format": "exact" },
|
|
* { "match": "dan*", "policy": "allow", "format": "glob" }
|
|
* ],
|
|
* "policy": "deny"
|
|
* }
|
|
*
|
|
* The object can be created on the command line using
|
|
*
|
|
* -object authz-list-file,id=authz0,\
|
|
* filename=/etc/qemu/myvm-vnc.acl,refresh=on
|
