From a6b75b837f5e851c80f8f2dc508b11f1693af1b3 Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Mon, 20 Mar 2017 17:38:55 +0100 Subject: evaluate: set: Allow for set elems to be sets Recursive use of sets is handled in parts by parser_bison.y, which has a rule for inline unnamed sets in set_list_member_expr, e.g. like this: | add rule ip saddr { { 1.1.1.0, 2.2.2.0 }, 3.3.3.0 } Yet there is another way to have an unnamed set inline, which is via define: | define myset = { | 1.1.1.0, | 2.2.2.0, | } | add rule ip saddr { $myset, 3.3.3.0 } This didn't work because the inline set comes in as EXPR_SET_ELEM with EXPR_SET as key. This patch handles that case by replacing the former by a copy of the latter, so the following set list merging can take place.
