Hello netfilter developers!
I suspect a small bug in /kernel/net/ipv4/netfilter/ip_tables.c __do_replace()
function. xt_replace_table() may return NULL when allocation of memory was not
successful by xt_replace_table->xt_jumpstack_alloc() (in my case I suspect
there were no free memory when it's happened):
...
oldinfo = xt_replace_table(t, num_counters, newinfo, &ret);
if (!oldinfo)
goto put_module;
The full bactrace is
