[libvirt] [PATCH 0/8] Make NSS module lookup by libvirt domain names too

[Michal Privoznik]

So far, the NSS module relies on guests providing hostnames
during DHCP transaction, because if they do it's recorded in a
json file that NSS module consults when doing the hostname
translation. But there are few cases where this is not enough:
some system (e.g. old RHEL6) don't provide hostname at all.

If that's the case we can maintain a separate file $bridge.macs
where we would keep a list of pairs <domain, mac address list>.
Thus next time when doing hostname translation we can look up MAC
address list for given domain, and then lookup the MAC <-> IP
mapping in $bridge.status. It's a bit clunky, but it's our best
shot.

Michal Privoznik (8):
  network: Don't unlock non-locked network driver
  nssmock: Prefer free() over VIR_FREE()
  virstring: Introduce virStringListAdd
  virstring: Introduce virStringListRemove
  util: Introduce virFileRewriteStr
  util: Introduce virMACMap module
  network: Track MAC address map
  nss: Lookup by libvirt domain names too
