…bles-nft Since kernels 6.17, support for netfilter legacy tables were disabled by default [1] but iptables package needs Netfilter legacy tables support enabled in the kernel when nftables compat is not enabled. Make sure to enable CONFIG_IP_NF_IPTABLES_LEGACY and CONFIG_NETFILTER_XTABLES_LEGACY for kernels >= 6.17. Fixes: [BRTEST# iptables --flush modprobe: module ip_tables not found in modules.dep iptables v1.8.11 (legacy): can't initialize iptables table `filter': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. On the other hand, when nftables compat (iptables-nft) is used by default (BR2_PACKAGE_IPTABLES_NFTABLES_DEFAULT=y) we have to enable nft protocol support in the kernel. iptables --version iptables: Failed to initialize nft: Protocol not supported Enable CONFIG_NF_TABLES and CONFIG_NF_TABLES_INET as for NFTABLES_LINUX_CONFIG_FIXUPS and complete the list with CONFIG_NFT_SOCKET needed to pass the TestIptables with nftables compat (iptables-nft) enabled. Without CONFIG_NFT_SOCKET: iptables --policy INPUT ACCEPT iptables v1.8.11 (nf_tables): TABLE_ADD failed (Operation not supported): table filter So, enable kernel support for iptables-legacy only if nftables compat is not enabled by default. Enable iptables-nft support when nftables compat is enabled, even if not used by default.

TestIptables expect netfilter legacy tables enabled in the kernel. Make sure we use iptables-legacy: iptables --version iptables v1.8.11 (legacy) The test would fail if nftables compat (iptables-nft) is enabled. iptables --version iptables v1.8.11 (nf_tables) Add the following configuration fragment to enable iptables-nft: BR2_PACKAGE_IPTABLES_NFTABLES=y BR2_PACKAGE_IPTABLES_NFTABLES_DEFAULT=y Acked-by: Fiona Klute <fiona.klute@gmx.de> Tested-by: Fiona Klute <fiona.klute@gmx.de> Signed-off-by: Romain Naour <romain.naour@smile.fr> Signed-off-by: Fiona Klute <fiona.klute@gmx.de>
