[libvirt] [PATCH 1/2] qemu: Support SPICE listen over unix socket

Add support for SPICE listen over unix socket. This has been in qemu since v2.3. The XML is: <spice socket='/path/to/socket'/> Which matches support for VNC listen over unix socket. https://bugzilla.redhat.com/show_bug.cgi?id=1151761 --- docs/schemas/domaincommon.rng | 5 ++++ src/conf/domain_conf.c | 26 +++++++++++++-------- src/conf/domain_conf.h | 1 + src/qemu/qemu_command.c | 4 +++- src/qemu/qemu_process.c | 3 +++ src/security/virt-aa-helper.c | 5 ++++ .../qemuxml2argv-graphics-spice-unix.args | 21 +++++++++++++++++ .../qemuxml2argv-graphics-spice-unix.xml | 27 ++++++++++++++++++++++ tests/qemuxml2argvtest.c | 4 ++++ 9 files changed, 85 insertions(+), 11 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-graphics-spice-unix.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-graphics-spice-unix.xml diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index da6de40..4d3f951 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -2700,6 +2700,11 @@ </attribute> </optional> <optional> + <attribute name="socket"> + <ref name="absFilePath"/> + </attribute> + </optional> + <optional> <attribute name="passwdValidTo"> <data type="dateTime"/> </attribute> diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index d5d9ff7..985d8bd 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -1249,6 +1249,7 @@ void virDomainGraphicsDefFree(virDomainGraphicsDefPtr def) break; case VIR_DOMAIN_GRAPHICS_TYPE_SPICE: + VIR_FREE(def->data.spice.socket); VIR_FREE(def->data.spice.keymap); virDomainGraphicsAuthDefClear(&def->data.spice.auth); break; @@ -10986,6 +10987,7 @@ virDomainGraphicsDefParseXML(xmlNodePtr node, def->data.spice.tlsPort = 0; } + def->data.spice.socket = virXMLPropString(node, "socket"); def->data.spice.keymap = virXMLPropString(node, "keymap"); if (virDomainGraphicsAuthDefParseXML(node, &def->data.spice.auth, @@ -21267,19 +21269,23 @@ virDomainGraphicsDefFormat(virBufferPtr buf, break; case VIR_DOMAIN_GRAPHICS_TYPE_SPICE: - if (def->data.spice.port) - virBufferAsprintf(buf, " port='%d'", - def->data.spice.port); + if (def->data.spice.socket) { + virBufferEscapeString(buf, " socket='%s'", def->data.spice.socket); + } else { + if (def->data.spice.port) + virBufferAsprintf(buf, " port='%d'", + def->data.spice.port); - if (def->data.spice.tlsPort) - virBufferAsprintf(buf, " tlsPort='%d'", - def->data.spice.tlsPort); + if (def->data.spice.tlsPort) + virBufferAsprintf(buf, " tlsPort='%d'", + def->data.spice.tlsPort); - virBufferAsprintf(buf, " autoport='%s'", - def->data.spice.autoport ?
