From de340a7f1a9cf21931d94ea8814545c4b2d172b0 Mon Sep 17 00:00:00 2001 From: Jozsef Kadlecsik Date: Mon, 21 Sep 2020 10:21:39 +0200 Subject: Add bucketsize parameter to all hash types The parameter defines the upper limit in any hash bucket at adding new entries from userspace - if the limit would be exceeded, ipset doubles the hash size and rehashes. It means the set may consume more memory but gives faster evaluation at matching in the set.
