Right.

Yes, I have an idea. Pass an interface index (instead of a string) to
port_link_status(), and then you can remove the ugly code.
if (cb)
device = calloc(1, sizeof(MAX_IFNAME_SIZE + 1));
else
device = (char *)ctx;
Then you can also simplify this block
if (bond[IFLA_BOND_ACTIVE_SLAVE]) {
index =
rta_getattr_u32(bond[IFLA_BOND_ACTIVE_SLAVE]);
if (!if_indextoname(index, device)) {
pr_err("failed to get device name: %m");
return -1;
}
}
by removing the if_indextoname() call.
Thanks,
Richard
