This introduces a new event type
VIR_DOMAIN_EVENT_ID_GRAPHICS
The same event can be emitted in 3 scenarioes
typedef enum {
VIR_DOMAIN_EVENT_GRAPHICS_CONNECT = 0,
VIR_DOMAIN_EVENT_GRAPHICS_INITIALIZE,
VIR_DOMAIN_EVENT_GRAPHICS_DISCONNECT,
} virDomainEventGraphicsPhase;
Connect/disconnect are triggered at socket accept/close.
The initailize phase is immediately after the protocol
setup and authentication has completed. ie when the
client is authorized and about to start interacting with
the graphical desktop
This event comes with *alot* of potential information
- IP address, port & address family of client
- IP address, port & address family of server
- Authentication scheme (arbitrary string)
- Authenticated subject identity. A subject may have
multiple identities with some authentication schemes.
For example, vencrypt+sasl results in a x509dname
and saslUsername identities.
This results in a very complicated callback :-(
typedef enum {
VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV4,
VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV6,
} virDomainEventGraphicsAddressType;
struct _virDomainEventGraphicsAddress {
int family;
const char *node;
const char *service;
};
typedef struct _virDomainEventGraphicsAddress virDomainEventGraphicsAddress;
typedef virDomainEventGraphicsAddress *virDomainEventGraphicsAddressPtr;
struct _virDomainEventGraphicsSubject {
int nidentity;
struct {
const char *type;
const char *name;
} *identities;
};
typedef struct _virDomainEventGraphicsSubject virDomainEventGraphicsSubject;
typedef virDomainEventGraphicsSubject *virDomainEventGraphicsSubjectPtr;
typedef void (*virConnectDomainEventGraphicsCallback)(virConnectPtr conn,
virDomainPtr dom,
int phase,
virDomainEventGraphicsAddressPtr local,
virDomainEventGraphicsAddressPtr remote,
const char *authScheme,
virDomainEventGraphicsSubjectPtr subject,
void *opaque);
The wire protocol is similarly complex
struct remote_domain_event_graphics_address {
int family;
remote_nonnull_string node;
remote_nonnull_string service;
};
const REMOTE_DOMAIN_EVENT_GRAPHICS_IDENTITY_MAX = 20;
struct remote_domain_event_graphics_identity {
remote_nonnull_string type;
remote_nonnull_string name;
};
struct remote_domain_event_graphics_msg {
remote_nonnull_domain dom;
int phase;
remote_domain_event_graphics_address local;
remote_domain_event_graphics_address remote;
remote_nonnull_string authScheme;
remote_domain_event_graphics_identity subject<REMOTE_DOMAIN_EVENT_GRAPHICS_IDENTITY_MAX>;
};
This is currently implemented in QEMU for the VNC graphics
protocol, but designed to be usable with SPICE graphics in
the future too.
