Re: [libvirt] [PATCH] Emit graphics events when a SPICE client connects/disconnects

Wire up the domain graphics event notifications for SPICE. Adapted from a RHEL-only patch written by Dan Berrange that used custom __com.redhat_SPICE events - equivalent events are now available in upstream QEMU (including a SPICE_CONNECTED event, which was missing in the __COM.redhat_SPICE version). * src/qemu/qemu_monitor_json.c: Wire up SPICE graphics events --- src/qemu/qemu_monitor_json.c | 56 +++++++++++++++++++++++++++++++++++++++--- 1 files changed, 52 insertions(+), 4 deletions(-) diff --git a/src/qemu/qemu_monitor_json.c b/src/qemu/qemu_monitor_json.c index 1a0ee94..a5ef1d4 100644 --- a/src/qemu/qemu_monitor_json.c +++ b/src/qemu/qemu_monitor_json.c @@ -59,6 +59,9 @@ static void qemuMonitorJSONHandleVNCConnect(qemuMonitorPtr mon, virJSONValuePtr static void qemuMonitorJSONHandleVNCInitialize(qemuMonitorPtr mon, virJSONValuePtr data); static void qemuMonitorJSONHandleVNCDisconnect(qemuMonitorPtr mon, virJSONValuePtr data); static void qemuMonitorJSONHandleBlockJob(qemuMonitorPtr mon, virJSONValuePtr data); +static void qemuMonitorJSONHandleSPICEConnect(qemuMonitorPtr mon, virJSONValuePtr data); +static void qemuMonitorJSONHandleSPICEInitialize(qemuMonitorPtr mon, virJSONValuePtr data); +static void qemuMonitorJSONHandleSPICEDisconnect(qemuMonitorPtr mon, virJSONValuePtr data); static struct { const char *type; @@ -75,6 +78,9 @@ static struct { { "VNC_INITIALIZED", qemuMonitorJSONHandleVNCInitialize, }, { "VNC_DISCONNECTED", qemuMonitorJSONHandleVNCDisconnect, }, { "BLOCK_JOB_COMPLETED", qemuMonitorJSONHandleBlockJob, }, + { "SPICE_CONNECTED", qemuMonitorJSONHandleSPICEConnect, }, + { "SPICE_INITIALIZED", qemuMonitorJSONHandleSPICEInitialize, }, + { "SPICE_DISCONNECTED", qemuMonitorJSONHandleSPICEDisconnect, }, }; @@ -624,7 +630,7 @@ VIR_ENUM_IMPL(qemuMonitorGraphicsAddressFamily, VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_LAST, "ipv4", "ipv6", "unix"); -static void qemuMonitorJSONHandleVNC(qemuMonitorPtr mon, virJSONValuePtr data, int phase) +static void qemuMonitorJSONHandleGraphics(qemuMonitorPtr mon, virJSONValuePtr data, int phase) { const char *localNode, *localService, *localFamily; const char *remoteNode, *remoteService, *remoteFamily; @@ -643,14 +649,38 @@ static void qemuMonitorJSONHandleVNC(qemuMonitorPtr mon, virJSONValuePtr data, i } authScheme = virJSONValueObjectGetString(server, "auth"); + if (!authScheme) { + VIR_WARN("missing auth scheme in graphics event"); + return; + } localFamily = virJSONValueObjectGetString(server, "family"); + if (!authScheme) {
