[PATCH net 0/3] netfilter updates for net

[Florian Westphal <fw@strlen.de>]

Hello,

The following three patches fix regressions in the netfilter subsystem:

1. Reject attempts to repeatedly toggle the 'dormant' flag in a single
   transaction.  Doing so makes nf_tables lose track of the real state
   vs. the desired state.  This ends with an attempt to unregister hooks
   that were never registered in the first place, which yields a splat.

2. Fix element counting in the new nftables garbage collection infra
   that came with 6.5:  More than 255 expired elements wraps a counter
   which results in memory leak.

3. Since 6.4 ipset can BUG when a set is renamed while a CREATE command
   is in progress, fix from Jozsef Kadlecsik.

The following changes since commit 4e4b1798cc90e376b8b61d0098b4093898a32227:

  vxlan: Add missing entries to vxlan_get_size() (2023-09-20 09:00:54 +0100)
