From 98dbe2dded157a753a56df30faba3f5f51dc35f7 Mon Sep 17 00:00:00 2001 From: Ben Pfaff Date: Tue, 24 May 2011 11:02:31 -0700 Subject: [PATCH] bridge: Avoid "cast increases required alignment of target type" warning. This pointer arithmetic caused a warning on sparc. One alternative would be to add a cast through "void *", but it seems at least as reasonable to just use a few macros to do direct assignments. --- vswitchd/bridge.c | 61 +++++++++++++++++++++-------------------------- 1 file changed, 27 insertions(+), 34 deletions(-) diff --git a/vswitchd/bridge.c b/vswitchd/bridge.c index 4b5d0faa..58053056 100644 --- a/vswitchd/bridge.c +++ b/vswitchd/bridge.c @@ -1252,30 +1252,25 @@ iface_refresh_lacp_stats(struct iface *iface) static void iface_refresh_stats(struct iface *iface) { - struct iface_stat { - char *name; - int offset; - }; - static const struct iface_stat iface_stats[] = { - { "rx_packets", offsetof(struct netdev_stats, rx_packets) }, - { "tx_packets", offsetof(struct netdev_stats, tx_packets) }, - { "rx_bytes", offsetof(struct netdev_stats, rx_bytes) }, - { "tx_bytes", offsetof(struct netdev_stats, tx_bytes) }, - { "rx_dropped", offsetof(struct netdev_stats, rx_dropped) }, - { "tx_dropped", offsetof(struct netdev_stats, tx_dropped) }, - { "rx_errors", offsetof(struct netdev_stats, rx_errors) }, - { "tx_errors", offsetof(struct netdev_stats, tx_errors) }, - { "rx_frame_err", offsetof(struct netdev_stats, rx_frame_errors) }, - { "rx_over_err", offsetof(struct netdev_stats, rx_over_errors) }, - { "rx_crc_err", offsetof(struct netdev_stats, rx_crc_errors) }, - { "collisions", offsetof(struct netdev_stats, collisions) }, - }; - enum { N_STATS = ARRAY_SIZE(iface_stats) }; - const struct iface_stat *s; - - char *keys[N_STATS]; - int64_t values[N_STATS]; - int n; +#define IFACE_STATS \ + IFACE_STAT(rx_packets, "rx_packets") \ + IFACE_STAT(tx_packets, "tx_packets") \ + IFACE_STAT(rx_bytes, "rx_bytes") \ + IFACE_STAT(tx_bytes, "tx_bytes") \ + IFACE_STAT(rx_dropped, "rx_dropped") \ + IFACE_STAT(tx_dropped, "tx_dropped") \ + IFACE_STAT(rx_errors, "rx_errors") \ + IFACE_STAT(tx_errors, "tx_errors") \ + IFACE_STAT(rx_frame_errors, "rx_frame_err") \ + IFACE_STAT(rx_over_errors, "rx_over_err") \ + IFACE_STAT(rx_crc_errors, "rx_crc_err") \ + IFACE_STAT(collisions, "collisions") + +#define IFACE_STAT(MEMBER, NAME) NAME, + static char *keys[] = { IFACE_STATS }; +#undef IFACE_STAT + int64_t values[ARRAY_SIZE(keys)]; + int i; struct netdev_stats stats; @@ -1287,17 +1282,15 @@ iface_refresh_stats(struct iface *iface) * all-1s, and we will deal with that correctly below. */ netdev_get_stats(iface->netdev, &stats); - n = 0; - for (s = iface_stats; s < &iface_stats[N_STATS]; s++) { - uint64_t value = *(uint64_t *) (((char *) &stats) + s->offset); - if (value != UINT64_MAX) { - keys[n] = s->name; - values[n] = value; - n++; - } - } + /* Copy statistics into values[] array. */ + i = 0; +#define IFACE_STAT(MEMBER, NAME) values[i++] = stats.MEMBER; + IFACE_STATS; +#undef IFACE_STAT + assert(i == ARRAY_SIZE(keys)); - ovsrec_interface_set_statistics(iface->cfg, keys, values, n); + ovsrec_interface_set_statistics(iface->cfg, keys, values, ARRAY_SIZE(keys)); +#undef IFACE_STATS } static void -- 2.30.2
