From 72a88a128ebb386307e9d3ef1b71cefa52c7a0af Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Thu, 9 Feb 2023 10:27:57 +0100 Subject: [PATCH] netlink_delinearize: also postprocess OP_AND in set element context Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2094887 Upstream Status: nftables commit b1e3ed0335d13 commit b1e3ed0335d13d206a2a2698a1ba189fa396dbf3 Author: Florian Westphal Date: Mon Aug 1 13:03:18 2022 +0200 netlink_delinearize: also postprocess OP_AND in set element context Pablo reports: add rule netdev nt y update @macset { vlan id timeout 5s } listing still shows the raw expression: update @macset { @ll,112,16 & 0xfff timeout 5s } so also cover the 'set element' case.
