Re: [libvirt] [PATCH 2/5] list: Implemente RPC calls for virConnectListAllInterfaces

The RPC generator doesn't support returning list of object yet, this patch do the work manually. * daemon/remote.c: Implemente the server side handler remoteDispatchConnectListAllInterfaces. * src/remote/remote_driver.c: Add remote driver handler remoteConnectListAllInterfaces. * src/remote/remote_protocol.x: New RPC procedure REMOTE_PROC_CONNECT_LIST_ALL_INTERFACES and structs to represent the args and ret for it. * src/remote_protocol-structs: Likewise. --- daemon/remote.c | 54 +++++++++++++++++++++++++++++++++++ src/remote/remote_driver.c | 64 ++++++++++++++++++++++++++++++++++++++++++ src/remote/remote_protocol.x | 13 ++++++++- src/remote_protocol-structs | 12 ++++++++ 4 files changed, 142 insertions(+), 1 deletions(-) diff --git a/daemon/remote.c b/daemon/remote.c index dba51a7..fe2f9dd 100644 --- a/daemon/remote.c +++ b/daemon/remote.c @@ -4265,6 +4265,60 @@ cleanup: return rv; } +static int +remoteDispatchConnectListAllInterfaces(virNetServerPtr server ATTRIBUTE_UNUSED, + virNetServerClientPtr client, + virNetMessagePtr msg ATTRIBUTE_UNUSED, + virNetMessageErrorPtr rerr, + remote_connect_list_all_interfaces_args *args, + remote_connect_list_all_interfaces_ret *ret) +{ + virInterfacePtr *ifaces = NULL; + int nifaces = 0; + int i; + int rv = -1; + struct daemonClientPrivate *priv = virNetServerClientGetPrivateData(client); + + if (!priv->conn) { + virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("connection not open")); + goto cleanup; + } + + if ((nifaces = virConnectListAllInterfaces(priv->conn, + args->need_results ? &ifaces : NULL, + args->flags)) < 0) + goto cleanup; + + if (ifaces && nifaces) { + if (VIR_ALLOC_N(ret->ifaces.ifaces_val, nifaces) < 0) { + virReportOOMError(); + goto cleanup; + } + + ret->ifaces.ifaces_len = nifaces; + + for (i = 0; i < nifaces; i++) + make_nonnull_interface(ret->ifaces.ifaces_val + i, ifaces[i]); + } else { + ret->ifaces.ifaces_len = 0; + ret->ifaces.ifaces_val = NULL; + } + + ret->ret = nifaces; + + rv = 0; + +cleanup: + if (rv < 0) + virNetMessageSaveError(rerr); + if (ifaces) { + for (i = 0; i < nifaces; i++) + virInterfaceFree(ifaces[i]); + VIR_FREE(ifaces); + } + return rv; +} + /*----- Helpers. -----*/ diff --git a/src/remote/remote_driver.c b/src/remote/remote_driver.c index 56e50a6..5c97061 100644 --- a/src/remote/remote_driver.c +++ b/src/remote/remote_driver.c @@ -2781,6 +2781,69 @@ done: return rv; } +static int +remoteConnectListAllInterfaces(virConnectPtr conn, + virInterfacePtr **ifaces, + unsigned int flags) +{ + int rv = -1; + int i; + virInterfacePtr *tmp_ifaces = NULL; + remote_connect_list_all_interfaces_args args; + remote_connect_list_all_interfaces_ret ret; + + struct private_data *priv = conn->privateData; + + remoteDriverLock(priv); + + args.need_results = !!ifaces; + args.flags = flags; + + memset(&ret, 0, sizeof(ret)); + if (call(conn, + priv, + 0, + REMOTE_PROC_CONNECT_LIST_ALL_INTERFACES, + (xdrproc_t) xdr_remote_connect_list_all_interfaces_args, + (char *) &args, + (xdrproc_t) xdr_remote_connect_list_all_interfaces_ret, + (char *) &ret) == -1) + goto done; + + if (ifaces) { + if (VIR_ALLOC_N(tmp_ifaces, ret.ifaces.ifaces_len + 1) < 0) { + virReportOOMError(); + goto cleanup; + } + + for (i = 0; i < ret.ifaces.ifaces_len; i++) { + tmp_ifaces[i] = get_nonnull_interface (conn, ret.ifaces.ifaces_val[i]); + if (!tmp_ifaces[i]) { + virReportOOMError(); + goto cleanup; + } + } + *ifaces = tmp_ifaces; + tmp_ifaces = NULL; + } + + rv = ret.ret; + +cleanup: + if (tmp_ifaces) { + for (i = 0; i < ret.ifaces.ifaces_len; i++) + if (tmp_ifaces[i]) + virInterfaceFree(tmp_ifaces[i]); + VIR_FREE(tmp_ifaces); + }
