If mkdir() fails due to any reason than "already exists", the subsequent call to open() fails and the error is detected and corectly processed by the code. --- mesh/keyring.c | 9 +++------ 1 file changed, 3 insertions(+), 6 deletions(-) diff --git a/mesh/keyring.c b/mesh/keyring.c index 1ef4fc3ef..0b74ee914 100644 --- a/mesh/keyring.c +++ b/mesh/keyring.c @@ -51,8 +51,7 @@ bool keyring_put_net_key(struct mesh_node *node, uint16_t net_idx, snprintf(key_file, PATH_MAX, "%s%s", node_path, net_key_dir); - if (!mkdir(key_file, 0755)) - return false; + mkdir(key_file, 0755); snprintf(key_file, PATH_MAX, "%s%s/%3.3x", node_path, net_key_dir, net_idx); @@ -88,8 +87,7 @@ bool keyring_put_app_key(struct mesh_node *node, uint16_t app_idx, snprintf(key_file, PATH_MAX, "%s%s", node_path, app_key_dir); - if (!mkdir(key_file, 0755)) - return false; + mkdir(key_file, 0755); snprintf(key_file, PATH_MAX, "%s%s/%3.3x", node_path, app_key_dir, app_idx); @@ -207,8 +205,7 @@ bool keyring_put_remote_dev_key(struct mesh_node *node, uint16_t unicast, snprintf(key_file, PATH_MAX, "%s%s", node_path, dev_key_dir); - if (!mkdir(key_file, 0755)) - return false; + mkdir(key_file, 0755); for (i = 0; i < count; i++) { snprintf(key_file, PATH_MAX, "%s%s/%4.4x", node_path,
