From 2199c981767085d12529edc6bf15b046357ec7aa Mon Sep 17 00:00:00 2001 From: Lubomir Rintel Date: Sat, 7 Sep 2019 17:18:55 +0200 Subject: [PATCH] libertas: use mesh_wdev->ssid instead of priv->mesh_ssid With the commit e86dc1ca4676 ("Libertas: cfg80211 support") we've lost the ability to actually set the Mesh SSID from userspace. NL80211_CMD_SET_INTERFACE with NL80211_ATTR_MESH_ID sets the mesh point interface's ssid field. Let's use that one for the Libertas Mesh operation Signed-off-by: Lubomir Rintel Signed-off-by: Kalle Valo --- drivers/net/wireless/marvell/libertas/dev.h | 2 -- drivers/net/wireless/marvell/libertas/mesh.c | 31 ++++++++++++++++++---------- drivers/net/wireless/marvell/libertas/mesh.h | 3 +-- 3 files changed, 21 insertions(+), 15 deletions(-) diff --git a/drivers/net/wireless/marvell/libertas/dev.h b/drivers/net/wireless/marvell/libertas/dev.h index 469134930026..4b6e05a8e5d5 100644 --- a/drivers/net/wireless/marvell/libertas/dev.h +++ b/drivers/net/wireless/marvell/libertas/dev.h @@ -58,8 +58,6 @@ struct lbs_private { #ifdef CONFIG_LIBERTAS_MESH struct lbs_mesh_stats mstats; uint16_t mesh_tlv; - u8 mesh_ssid[IEEE80211_MAX_SSID_LEN + 1]; - u8 mesh_ssid_len; u8 mesh_channel; #endif diff --git a/drivers/net/wireless/marvell/libertas/mesh.c b/drivers/net/wireless/marvell/libertas/mesh.c index 2315fdff56c2..2747c957d18c 100644 --- a/drivers/net/wireless/marvell/libertas/mesh.c +++ b/drivers/net/wireless/marvell/libertas/mesh.c @@ -86,6 +86,7 @@ static int lbs_mesh_config_send(struct lbs_private *priv, static int lbs_mesh_config(struct lbs_private *priv, uint16_t action, uint16_t chan) { + struct wireless_dev *mesh_wdev; struct cmd_ds_mesh_config cmd; struct mrvl_meshie *ie; @@ -105,10 +106,17 @@ static int lbs_mesh_config(struct lbs_private *priv, uint16_t action, ie->val.active_protocol_id = MARVELL_MESH_PROTO_ID_HWMP; ie->val.active_metric_id = MARVELL_MESH_METRIC_ID; ie->val.mesh_capability = MARVELL_MESH_CAPABILITY; - ie->val.mesh_id_len = priv->mesh_ssid_len; - memcpy(ie->val.mesh_id, priv->mesh_ssid, priv->mesh_ssid_len); + + if (priv->mesh_dev) { + mesh_wdev = priv->mesh_dev->ieee80211_ptr; + ie->val.mesh_id_len = mesh_wdev->mesh_id_up_len; + memcpy(ie->val.mesh_id, mesh_wdev->ssid, + mesh_wdev->mesh_id_up_len); + } + ie->len = sizeof(struct mrvl_meshie_val) - - IEEE80211_MAX_SSID_LEN + priv->mesh_ssid_len; + IEEE80211_MAX_SSID_LEN + ie->val.mesh_id_len; + cmd.length = cpu_to_le16(sizeof(struct mrvl_meshie_val)); break; case CMD_ACT_MESH_CONFIG_STOP: @@ -117,8 +125,8 @@ static int lbs_mesh_config(struct lbs_private *priv, uint16_t action, return -1; } lbs_deb_cmd("mesh config action %d type %x channel %d SSID %*pE\n", - action, priv->mesh_tlv, chan, priv->mesh_ssid_len, - priv->mesh_ssid); + action, priv->mesh_tlv, chan, ie->val.mesh_id_len, + ie->val.mesh_id); return __lbs_mesh_config_send(priv, &cmd, action, priv->mesh_tlv); } @@ -863,12 +871,6 @@ int lbs_init_mesh(struct lbs_private *priv) /* Stop meshing until interface is brought up */ lbs_mesh_config(priv, CMD_ACT_MESH_CONFIG_STOP, 1); - if (priv->mesh_tlv) { - sprintf(priv->mesh_ssid, "mesh"); - priv->mesh_ssid_len = 4; - ret = 1; - } - return ret; } @@ -997,6 +999,13 @@ static int lbs_add_mesh(struct lbs_private *priv) mesh_wdev->iftype = NL80211_IFTYPE_MESH_POINT; mesh_wdev->wiphy = priv->wdev->wiphy; + + if (priv->mesh_tlv) { + sprintf(mesh_wdev->ssid, "mesh"); + mesh_wdev->mesh_id_up_len = 4; + ret = 1; + } + mesh_wdev->netdev = mesh_dev; mesh_dev->ml_priv = priv; diff --git a/drivers/net/wireless/marvell/libertas/mesh.h b/drivers/net/wireless/marvell/libertas/mesh.h index dfe22c91aade..1561018f226f 100644 --- a/drivers/net/wireless/marvell/libertas/mesh.h +++ b/drivers/net/wireless/marvell/libertas/mesh.h @@ -24,8 +24,7 @@ void lbs_remove_mesh(struct lbs_private *priv); static inline bool lbs_mesh_activated(struct lbs_private *priv) { - /* Mesh SSID is only programmed after successful init */ - return priv->mesh_ssid_len != 0; + return !!priv->mesh_tlv; } int lbs_mesh_set_channel(struct lbs_private *priv, u8 channel); -- 2.11.0
