There has been a behavior regression reported in nftables when
upgrading from Debian 11 Bullseye to Debian 12 Bookworm.
The change is in how nftables prints the set definitions, with
or without set elements by default.
Some user tools relying on 'nft -j list sets' fail after upgrading
to Debian Bookworm from Debian Bullseye because the behavior change.
The small upstream fix makes the behavior coherent and predictable for the
set listing action.
There is not much risk in this update:
* The fix patch has been provided directly by upstream
* The fix has been applied to upstream main branch already
* The fix is already in Debian Sid

+Subject: cache: include set elements in "nft set list"
+
+Make "nft list sets" include set elements in listing by default.
+In nftables 1.0.0, "nft list sets" did not include the set elements,
+but with "--json" they were included.
+
+1.0.1 and newer never include them.
+This causes a problem for people updating from 1.0.0 and relying
+on the presence of the set elements.
+
+Change nftables to always include the set elements.
+The "--terse" option is honored to get the "no elements" behaviour.
+
+Fixes: a1a6b0a5c3c4 ("cache: finer grain cache population for list commands")
