netfilter: conntrack: allow increasing bucket size via sysctl too
No need to restrict this to module parameter.
We export a copy of the real hash size -- when user alters the value we
allocate the new table, copy entries etc before we update the real size
to the requested one.
This is also needed because the real size is used by concurrent readers
and cannot be changed without synchronizing the conntrack generation
seqcnt.
We only allow changing this value from the initial net namespace.
Tested using http-client-benchmark vs. httpterm with concurrent
while true;do
echo $RANDOM > /proc/sys/net/netfilter/nf_conntrack_buckets
done
