Hi 1. in the callback o2net_fill_node_map -> o2net_tx_can_proceed() 2. if the function o2net_tx_can_proceed returns false, then "ret" and sc are uninialized, and re-using the value from the previous iteration. I think this is not reasonable. I do not know whether to hide a bug. checking the return value is harmless and robustness.
Finally, any feedback about this process (positive or negative) would be
greatly appreciated.
/* Get a map of all nodes to which this node is currently connected to */ne
void o2net_fill_node_map(unsigned long *map, unsigned bytes)
{
struct o2net_sock_container *sc = NULL;
int node, ret = 0;
BUG_ON(bytes < (BITS_TO_LONGS(O2NM_MAX_NODES) * sizeof(unsigned long)));
memset(map, 0, bytes);
for (node = 0; node < O2NM_MAX_NODES; ++node) {
if (!o2net_tx_can_proceed(o2net_nn_from_num(node), &sc, &ret))
continue;
if (!ret) {
set_bit(node, map);
sc_put(sc);
}
sc = NULL;
ret = 0;
}
}
