[libvirt] [PATCH v2 01/14] libxl: allow only 'ethernet' and 'bridge' interfaces, allow script there

Actually only those interface types are handled correctly so reject others instead of ignoring settings (i.e. treating as bridge/ethernet anyway). Also allow <script/> in 'ethernet' (which should be the only script-allowing type). Keep <script/> allowed in bridge to be compatible with legacy 'xen' driver. Changes in v2: - reject interfaces other than 'ethernet' or 'bridge' - change title to better match patch content (was "libxl: allow script for any network interface, not only bridge") - update description Signed-off-by: Marek Marczykowski-Górecki <marmarek(a)invisiblethingslab.com&gt; --- src/libxl/libxl_conf.c | 24 +++++++++++++----------- 1 file changed, 13 insertions(+), 11 deletions(-) diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index 90d563b..b9cb61e 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -563,18 +563,20 @@ libxlMakeNic(virDomainNetDefPtr l_nic, libxl_device_nic *x_nic) if (VIR_STRDUP(x_nic->ifname, l_nic->ifname) < 0) return -1; - if (l_nic->type == VIR_DOMAIN_NET_TYPE_BRIDGE) { - if (VIR_STRDUP(x_nic->bridge, l_nic->data.bridge.brname) < 0) - return -1; - if (VIR_STRDUP(x_nic->script, l_nic->script) < 0) - return -1; - } else { - if (l_nic->script) { - virReportError(VIR_ERR_CONFIG_UNSUPPORTED, - _("scripts are not supported on interfaces of type %s"), - virDomainNetTypeToString(l_nic->type)); + switch (l_nic->type) { + case VIR_DOMAIN_NET_TYPE_BRIDGE: + if (VIR_STRDUP(x_nic->bridge, l_nic->data.bridge.brname) < 0) + return -1; + /* fallthrough */ + case VIR_DOMAIN_NET_TYPE_ETHERNET: + if (VIR_STRDUP(x_nic->script, l_nic->script) < 0) + return -1; + break; + default: + virReportError(VIR_ERR_INTERNAL_ERROR, + _("libxenlight does not support network device type %s"), + virDomainNetTypeToString(l_nic->type)); return -1; - } } return 0; -- 1.8.1.4
