Hi,
I try to use the qdisc and class API of libnl and I can create a qdisc
root or qdisc leaf, but can't add a class on the qdisc root, I've got
this error :
Unable to connect netlink socketbind() failed (errno = Operation not permitted)
Function for add a class :
int add_class(struct nl_handle *nlh,
int ifindex,
char *hndl,
char *prt,
uint32_t prio,
uint32_t rate,
uint32_t ceil) {
struct rtnl_class *class;
uint32_t handle, parent;
int err = 0;
class = rtnl_class_alloc();
if (!class)
return -1;
rtnl_class_set_kind(class, "htb");
rtnl_class_set_ifindex(class, ifindex);
if (rtnl_tc_str2handle(hndl, &handle) < 0) {
fprintf(stderr, "%s\n", nl_geterror());
goto errout_free_class;
}
rtnl_class_set_handle(class, handle);
if (rtnl_tc_str2handle(prt, &parent) < 0) {
fprintf(stderr, "%s\n", nl_geterror());
goto errout_free_class;
}
rtnl_class_set_parent(class, parent);
if(prio)
rtnl_htb_set_prio(class, prio);
rtnl_htb_set_rate(class, rate);
if(ceil)
rtnl_htb_set_ceil(class, ceil);
if (nltool_connect(nlh, NETLINK_ROUTE) < 0)
goto errout_free_class;
if ((err = rtnl_class_add(nlh, class, NLM_F_REPLACE)) < 0) {
fprintf(stderr, "Unable to add Qdisc: %s\n", nl_geterror());
goto errout_add;
}
rtnl_class_put(class);
return err;
errout_free_class:
rtnl_class_put(class);
return -1;
errout_add:
rtnl_class_put(class);
return err;
}
Do you have an idea ?
Edouard.
