From 50ef784944c60cd291970c47e4b831ff7ef9c923 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Mon, 28 Feb 2022 20:02:17 +0100 Subject: [PATCH] Fix IPv6 sets nftables translation The parser assumes the set is an IPv4 ipset because IPSET_OPT_FAMILY is not set. # ipset-translate restore < ./ipset-mwan3_set_connected_ipv6.dump add table inet global add set inet global mwan3_connected_v6 { type ipv6_addr; flags interval; } flush set inet global mwan3_connected_v6 ipset v7.15: Error in line 4: Syntax error: '64' is out of range 0-32 Remove ipset_xlate_type_get(), call ipset_xlate_set_get() instead to obtain the set type and family.
