Hello,

Here are three netfilter fixes for the *net* tree:
1. On-demand overlap detection in 'rbtree' set can cause memory leaks.
   This is broken since 6.2.

2. An earlier fix in 6.4 to address an imbalance in refcounts during
   transaction error unwinding was incomplete, from Pablo Neira.

3. Disallow adding a rule to a deleted chain, also from Pablo.
   Broken since 5.9.

The following changes since commit d4a7ce642100765119a872d4aba1bf63e3a22c8a:

  igc: Fix Kernel Panic during ndo_tx_timeout callback (2023-07-26 09:54:40 +0100)
