[pve-devel] [PATCH docs/firewall/manager v6 0/4] autogenerate ipsets for sdn objects

[Stefan Hanreich]

This patch series adds support for autogenerating ipsets for SDN objects. It
autogenerates ipsets for every VNet as follows:

* ipset containing all IP ranges of the VNet
* ipset containing all gateways of the VNet
* ipset containing all IP ranges of the subnet - except gateways
* ipset containing all dhcp ranges of the vnet

Additionally it generates an IPSet for every guest that has one or more IPAM
entries in the pve IPAM.

Those can then be used in the cluster / host / guest firewalls. Firewall rules
automatically update on changes of the SDN / IPAM configuration. This patch
series works for the old firewall as well as the new firewall.

The ipsets in nftables currently get generated as named ipsets in every table,
this means that the `nft list ruleset` output can get quite crowded for large
SDN configurations or large IPAM databases. Another option would be to only
include them as anonymous IPsets in the rules, which would make the nft output
far less crowded but this way would use more memory when making extensive use of
the sdn ipsets, since everytime it is used in a rule we create an entirely new
ipset.

Dependencies:
* proxmox-perl-rs and proxmox-firewall depend on proxmox-ve-rs
* pve-firewall depends on proxmox-perl-rs
* pve-manager depends on pve-firewall

Changes from v5 to v6:
* Always load the full SDN configuration for the firewall instead of checking
  for the scope of the current user
* Filter the output of the refs endpoints to only show IPSets that the user has
  permission for
* Adapt create/update rule endpoints to only use IPSets from SDN config that the
  user has permission for

Changes from v4 to v5:
* extracted the API changes setting protected into a separate commit and put
  them up front
* fixed perl style issues - thanks @Thomas

Changes from v3 to v4:
* omitted proxmox-ve-rs since it is merged
* always load SDN configuration now when loading cluster config
* adapt is_nftables to check the flag file instead of reading the config
* gracefully fail when RPCEnvironment is not available

Changes from v2:
* rename end in IpRange to last to avoid confusion - thanks @Wolfgang
* bump Rust to 1.82 - thanks @Wolfgang
* improvements to the code generating IPSets - thanks @Wolfgang
* implement AsRef<str> for SDN name types - thanks @Wolfgang
* improve docstrings (proper capitalization and punctuation) - thanks @Wolfgang
* included a patch that removes proxmox-ve-config from proxmox-firewall

Changes from RFC:
* added documentation
* added separate SDN scope for IPSets
* rustfmt fixes
