| | 36 | * QAuthZListFile: |
| | 37 | * |
| | 38 | * This authorization driver provides a file mechanism |
| | 39 | * for granting access by matching user names against a |
| | 40 | * file of globs. Each match rule has an associated policy |
| | 41 | * and a catch all policy applies if no rule matches |
| | 42 | * |
| | 43 | * To create an instance of this class via QMP: |
| | 44 | * |
| | 45 | * { |
| | 46 | * "execute": "object-add", |
| | 47 | * "arguments": { |
| | 48 | * "qom-type": "authz-list-file", |
| | 49 | * "id": "authz0", |
| | 50 | * "props": { |
| | 51 | * "filename": "/etc/qemu/myvm-vnc.acl", |
| | 52 | * "refresh": true |
| | 53 | * } |
| | 54 | * } |
| | 55 | * } |
| | 56 | * |
| | 57 | * If 'refresh' is 'yes', inotify is used to monitor for changes |
| | 58 | * to the file and auto-reload the rules. |
| | 59 | * |
| | 60 | * The myvm-vnc.acl file should contain the parameters for |
| | 61 | * the QAuthZList object in JSON format: |
| | 62 | * |
| | 63 | * { |
| | 64 | * "rules": [ |
| | 65 | * { "match": "fred", "policy": "allow", "format": "exact" }, |
| | 66 | * { "match": "bob", "policy": "allow", "format": "exact" }, |
| | 67 | * { "match": "danb", "policy": "deny", "format": "exact" }, |
| | 68 | * { "match": "dan*", "policy": "allow", "format": "glob" } |
| | 69 | * ], |
| | 70 | * "policy": "deny" |
| | 71 | * } |
| | 72 | * |
| | 73 | * The object can be created on the command line using |
| | 74 | * |
| | 75 | * -object authz-list-file,id=authz0,\ |
| | 76 | * filename=/etc/qemu/myvm-vnc.acl,refresh=yes |
