[B.A.T.M.A.N.] [RFCv2 04/10] batman-adv: add bat_metric_get API function

From: Antonio Quartulli <antonio(a)open-mesh.com> Each routing algorithm may store its metric value in a different place, therefore a new API function is needed in order to ask the algorithm to return the metric of a given originator Signed-off-by: Antonio Quartulli <antonio(a)open-mesh.com> --- bat_iv_ogm.c | 9 +++++++++ main.c | 3 ++- types.h | 1 + 3 files changed, 12 insertions(+), 1 deletion(-) diff --git a/bat_iv_ogm.c b/bat_iv_ogm.c index 605c954..32e0321 100644 --- a/bat_iv_ogm.c +++ b/bat_iv_ogm.c @@ -1457,6 +1457,14 @@ next: seq_puts(seq, "No batman nodes in range ...\n"); } +static uint32_t batadv_iv_ogm_metric_get(struct batadv_neigh_node *neigh_node) +{ + if (!neigh_node) + return 0; + + return neigh_node->bat_iv.tq_avg; +} + static struct batadv_algo_ops batadv_batman_iv __read_mostly = { .name = "BATMAN_IV", .bat_iface_enable = batadv_iv_ogm_iface_enable, @@ -1465,6 +1473,7 @@ static struct batadv_algo_ops batadv_batman_iv __read_mostly = { .bat_primary_iface_set = batadv_iv_ogm_primary_iface_set, .bat_ogm_schedule = batadv_iv_ogm_schedule, .bat_ogm_emit = batadv_iv_ogm_emit, + .bat_metric_get = batadv_iv_ogm_metric_get, .bat_orig_print = batadv_iv_ogm_orig_print, }; diff --git a/main.c b/main.c index 46adf68..cc75126 100644 --- a/main.c +++ b/main.c @@ -445,7 +445,8 @@ int batadv_algo_register(struct batadv_algo_ops *bat_algo_ops) !bat_algo_ops->bat_iface_update_mac || !bat_algo_ops->bat_primary_iface_set || !bat_algo_ops->bat_ogm_schedule || - !bat_algo_ops->bat_ogm_emit) { + !bat_algo_ops->bat_ogm_emit || + !bat_algo_ops->bat_metric_get) { pr_info("Routing algo '%s' does not implement required ops\n", bat_algo_ops->name); ret = -EINVAL; diff --git a/types.h b/types.h index bff1668..e994fe0 100644 --- a/types.h +++ b/types.h @@ -1002,6 +1002,7 @@ struct batadv_algo_ops { void (*bat_primary_iface_set)(struct batadv_hard_iface *hard_iface); void (*bat_ogm_schedule)(struct batadv_hard_iface *hard_iface); void (*bat_ogm_emit)(struct batadv_forw_packet *forw_packet); + uint32_t (*bat_metric_get)(struct batadv_neigh_node *neigh_node); /* orig_node handling API */ void (*bat_orig_print)(struct batadv_priv *priv, struct seq_file *seq); }; -- 1.8.1.5
