Subject: ipset swap to nftables set
Date: Fri, 29 Sep 2023 15:44:14 +0200	[thread overview]
Message-ID: <befa0f8e-e76f-8671-81b1-587351b0cf53@gmail.com> (raw)

hi,

i'm using in production ipset swap with ~3000 ip addr

i.e.

- change coming from customer (new ips, old ips deprecated)

- generation of new list /etc/sysconfig/ipset-new

- swap ipset-new with ipset

transaction is near real-time


now i'm moving from RHEL7 to RHEL9 (rocky, kernel 5.14, nftables 1.0.4) 
and trying move from ipset to nftables sets

nft add set ip filter blackhole { type ipv4_addr\; comment \"drop all 
packets from these hosts\" \; }
fill the set

now the new flow is

- change coming from customer (new ips, old ips deprecated)

- nft flush set ip filter blackhole

- nft add element ip filter blackhole { X }   (bash for loop)


it tooks 10sec

can you recommend better way? (performance similar to ipset swap)

thanks

Marek
