Subject: [PATCH conntrack-tools] conntrackd: set default hashtable buckets and max entries if not specified
Date: Mon, 8 Mar 2021 16:32:54 +0100 [thread overview]
Message-ID: <20210308153254.15678-1-pablo@netfilter.org> (raw)
Fall back to 65536 buckets and 262144 entries.
It would be probably good to add code to autoadjust by reading
/proc/sys/net/netfilter/nf_conntrack_buckets and
/proc/sys/net/nf_conntrack_max.
Closes: https://bugzilla.netfilter.org/show_bug.cgi?id=1491
