Thanks to Heinz Wiesinger for these added python packages to implement
PEP 427 and PEP 517! Python modules are phasing out setup.py in favor of
building wheels, and then using python-installer to install them. These
are the bits needed to make that happen.
l/python-build-0.10.0-x86_64-1.txz:  Added.
l/python-flit-core-3.9.0-x86_64-1.txz:  Added.
l/python-glad2-2.0.4-x86_64-1.txz:  Added.
l/python-installer-0.7.0-x86_64-1.txz:  Added.
l/python-lxml-4.9.3-x86_64-1.txz:  Added.
l/python-pyproject-hooks-1.0.0-x86_64-1.txz:  Added.
l/python-tomli-w-1.0.0-x86_64-1.txz:  Added.
l/python-wheel-0.41.1-x86_64-1.txz:  Added.
n/nftables-1.0.8-x86_64-2.txz:  Rebuilt.
  Correctly generate nftables Python module using PEP 427/517 method.
  Thanks to marav.
n/openssh-9.4p1-x86_64-1.txz:  Upgraded.

+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")
+Tested-by: Brian Davidson <davidson.brian@gmail.com>
