[pve-devel] [PATCH pve-network 0/7] add dhcp support for all zones

[Alexandre Derumier <aderumier@odiso.com>]

This patch serie add dhcp support for all zones types.

also:
- Exec dnsmasq in a specific vrf if needed (currently only evpn)
- Enable-ra only on layer3 subnets



TO FIX:

- Dnsmasq is currently buggy with ipv6 && vrf (no crash but it's not listening), and need to be patched with:
https://thekelleys.org.uk/gitweb/?p=dnsmasq.git;a=commit;h=a889c554a7df71ff93a8299ef96037fbe05f2f55
I have tested it, just applying this patch on current debian source is enough to get is working.


- for layer2 network, we can't use a /128 for ipv6 like the /32 of ipv4.
  ipv6 range is large, so it shouldn't be a problem for user to have a free ip. (I can be the same on all vnets).
  But that mean we can't reuse the gateway ip (or it'll conflict).
  We need to be able to define a different ipv6 for dnsmasq server here. (and make it mandatory for ipv6 in this plugins)

- gateway should be optionnal (for user have 2 nic, 1 routable + 1 flat, we don't want to send 2 gateway).
  Use dnsmasq server ip field (like ipv6 layer 2 plugin ?) + empty gateway field
  don't announce ra for theses subnets (not sure how to handle this in dnsmasq range)


Alexandre Derumier (7):
  dhcp: add vrf support
  dhcp: enable-ra on layer3 zones only
  dnsmasq service: run service in vrf
  zones: evpn: add dhcp support
  zones: vlan: add dhcp support
  zones: qinq: add dhcp support
  zones: vxlan: add dhcp support
