Merge tag 'nf-next-24-01-29' of https://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next
Florian Westphal says:
====================
nf-next pr 2024-01-29
This batch contains updates for your *next* tree.
First three changes, from Phil Sutter, allow userspace to define
a table that is exclusively owned by a daemon (via netlink socket
aliveness) without auto-removing this table when the userspace program
exits. Such table gets marked as orphaned and a restarting management
daemon may re-attach/reassume ownership.
Next patch, from Pablo, passes already-validated flags variable around
rather than having called code re-fetch it from netlnik message.
Patches 5 and 6 update ipvs and nf_conncount to use the recently
introduced KMEM_CACHE() macro.
Last three patches, from myself, tweak kconfig logic a little to
permit a kernel configuration that can run iptables-over-nftables
but not classic (setsockopt) iptables.
Such builds lack the builtin-filter/mangle/raw/nat/security tables,
the set/getsockopt interface and the "old blob format"
interpreter/traverser. For now, this is 'oldconfig friendly', users
need to manually deselect existing config options for this.
