+Subject: meta: stash context statement length when generating payload/meta
+ dependency
+
+... meta mark set ip dscp
+
+generates an implicit dependency from the inet family to match on meta
+nfproto ip.
+
+The length of this implicit expression is incorrectly adjusted to the
+statement length, ie. relational to compare meta nfproto takes 4 bytes
+instead of 1 byte. The evaluation of 'ip dscp' under the meta mark
+statement triggers this implicit dependency which should not consider
+the context statement length since it is added before the statement
+itself.
+
+This problem shows when listing the ruleset, since netlink_parse_cmp()
+where left->len < right->len, hence handling the implicit dependency as
+a concatenation, but it is actually a bug in the evaluation step that
+leads to incorrect bytecode.
+
+Fixes: 3c64ea7995cb ("evaluate: honor statement length in integer evaluation")
+Fixes: edecd58755a8 ("evaluate: support shifts larger than the width of the left operand")
