From 0a9667ecdb6d7da90a2ef64194c70acd3876522a Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Tue, 11 Jul 2017 16:44:14 +0100 Subject: hmp: Update info vnc The QMP query-vnc interfaces have gained a lot more information that the HMP interfaces hasn't got yet. Update it. Note the output format has changed, but this is HMP so that's OK. In particular, this now includes client information for reverse connections: -vnc :0 (qemu) info vnc default: Server: 0.0.0.0:5900 (ipv4) Auth: none (Sub: none) (Now connect a client) (qemu) info vnc default: Server: 0.0.0.0:5900 (ipv4) Auth: none (Sub: none) Client: 127.0.0.1:51828 (ipv4) x509_dname: none sasl_username: none -vnc localhost:7000,reverse (qemu) info vnc default: Client: ::1:7000 (ipv6) x509_dname: none sasl_username: none Auth: none (Sub: none) -vnc :1,password,id=pass -vnc localhost:7000,reverse (qemu) info vnc default: Client: ::1:7000 (ipv6) x509_dname: none sasl_username: none Auth: none (Sub: none) rev: Server: 0.0.0.0:5901 (ipv4) Auth: vnc (Sub: none) Client: 127.0.0.1:53616 (ipv4) x509_dname: none sasl_username: none This was originally RH bz 1461682 Signed-off-by: Dr. David Alan Gilbert Reviewed-by: Markus Armbruster Message-id: 20170711154414.21111-1-dgilbert@redhat.com Signed-off-by: Gerd Hoffmann --- hmp.c | 104 ++++++++++++++++++++++++++++++++++++++++++++++-------------------- 1 file changed, 73 insertions(+), 31 deletions(-) (limited to 'hmp.c') diff --git a/hmp.c b/hmp.c index dee40284c1..3e1e766593 100644 --- a/hmp.c +++ b/hmp.c @@ -600,50 +600,92 @@ void hmp_info_blockstats(Monitor *mon, const QDict *qdict) qapi_free_BlockStatsList(stats_list); } +/* Helper for hmp_info_vnc_clients, _servers */ +static void hmp_info_VncBasicInfo(Monitor *mon, VncBasicInfo *info, + const char *name) +{ + monitor_printf(mon, " %s: %s:%s (%s%s)\n", + name, + info->host, + info->service, + NetworkAddressFamily_lookup[info->family], + info->websocket ?
