Netfilter fixes for net
The following patchset contains Netfilter fixes for net coming late
in the 5.17-rc process:
1) Revert port remap to mitigate shadowing service ports, this is causing
problems in existing setups and this mitigation can be achieved with
explicit ruleset, eg.
... tcp sport < 16386 tcp dport >= 32768 masquerade random
This patches provided a built-in policy similar to the one described above.
2) Disable register tracking infrastructure in nf_tables. Florian reported
two issues:
- Existing expressions with no implemented .reduce interface
that causes data-store on register should cancel the tracking.
- Register clobbering might be possible storing data on registers that
are larger than 32-bits.
This might lead to generating incorrect ruleset bytecode. These two
issues are scheduled to be addressed in the next release cycle.
