[PATCH -stable,5.15.x 0/5] Netfilter fixes for -stable

[Pablo Neira Ayuso <pablo@netfilter.org>]

Hi Greg, Sasha,

This batch contains a backport for recent fixes already upstream for 5.15.x.

The following list shows the backported patches, I am using original commit
IDs for reference:

1) b53c11664250 ("netfilter: nf_tables: set element extended ACK reporting support")

   This improves error reporting when adding more than one single element to set,
   it is not specifically fixing up a crash.

2) 7395dfacfff6 ("netfilter: nf_tables: use timestamp to check for set element timeout")

3) 3c13725f43dc ("netfilter: nf_tables: bail out if stateful expression provides no .clone")

4) fa23e0d4b756 ("netfilter: nf_tables: allow clone callbacks to sleep")

5) cff3bd012a95 ("netfilter: nf_tables: prefer nft_chain_validate")

Please, apply,
Thanks
