Re: [libvirt] [PATCHv2 3/7] Move code related to network routes to networkcommon_conf.[ch]

Moving code for parsing and formatting network routes to networkcommon_conf helps reusing those routes for domains. The route definition has been hidden to help reducing the number of unnecessary checks in the format function. --- po/POTFILES.in | 1 + src/Makefile.am | 3 +- src/conf/network_conf.c | 297 ++---------------------------- src/conf/network_conf.h | 22 +-- src/conf/networkcommon_conf.c | 414 ++++++++++++++++++++++++++++++++++++++++++ src/conf/networkcommon_conf.h | 72 ++++++++ src/libvirt_private.syms | 11 ++ src/network/bridge_driver.c | 44 ++--- 8 files changed, 526 insertions(+), 338 deletions(-) create mode 100644 src/conf/networkcommon_conf.c create mode 100644 src/conf/networkcommon_conf.h diff --git a/po/POTFILES.in b/po/POTFILES.in index 094c8e3..3064037 100644 --- a/po/POTFILES.in +++ b/po/POTFILES.in @@ -25,6 +25,7 @@ src/conf/netdev_bandwidth_conf.c src/conf/netdev_vlan_conf.c src/conf/netdev_vport_profile_conf.c src/conf/network_conf.c +src/conf/networkcommon_conf.c src/conf/node_device_conf.c src/conf/numatune_conf.c src/conf/nwfilter_conf.c diff --git a/src/Makefile.am b/src/Makefile.am index 216abac..4bba536 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -287,7 +287,8 @@ NETWORK_EVENT_SOURCES = \ # Network driver generic impl APIs NETWORK_CONF_SOURCES = \ - conf/network_conf.c conf/network_conf.h + conf/network_conf.c conf/network_conf.h \ + conf/networkcommon_conf.c conf/networkcommon_conf.h # Network filter driver generic impl APIs NWFILTER_PARAM_CONF_SOURCES = \ diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index 26fe18d..66f9b6c 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -163,12 +163,6 @@ virNetworkIpDefClear(virNetworkIpDefPtr def) } static void -virNetworkRouteDefClear(virNetworkRouteDefPtr def) -{ - VIR_FREE(def->family); -} - -static void virNetworkDNSTxtDefClear(virNetworkDNSTxtDefPtr def) { VIR_FREE(def->name); @@ -251,7 +245,7 @@ virNetworkDefFree(virNetworkDefPtr def) VIR_FREE(def->ips); for (i = 0; i < def->nroutes && def->routes; i++) - virNetworkRouteDefClear(&def->routes[i]); + virNetworkRouteDefFree(def->routes[i]); VIR_FREE(def->routes); for (i = 0; i < def->nPortGroups && def->portGroups; i++) @@ -1371,232 +1365,6 @@ virNetworkIPDefParseXML(const char *networkName, } static int -virNetworkRouteDefParseXML(const char *networkName, - xmlNodePtr node, - xmlXPathContextPtr ctxt, - virNetworkRouteDefPtr def) -{ - /* - * virNetworkRouteDef object is already allocated as part - * of an array.
