Hi,
With the set bitmap ipmac, if i had one, two hundred ip,mac in a set;
and do an ipset list,
i get an:
ipset v6.8: Kernel error received: No buffer space available
followed by a kernel panic (trace attached).
Maybe, in ip_set_core.c, can we modify the line 435 to this one:
if (ip_set_list[index] != NULL && ip_set_list[index]->ref !=0)
This way, we avoid the kernel panic?
Regards.
Sorry,
forgot to attached the kernel trace ...
