I have a working patch to have dnsmasq support RA instead of radvd.
However, something has come up and it will be a week to ten days before
I can get it in shape to submit.
The current patch has three variables added to the _virNetworkObj
structure: dnsmasqRA flag and both major and minor values for the
I use "dnsmasq --version" and then parse out the major/minor version
values. If major>2, then dnamsqFA=1. If major=2 and minor>=63, then
dnsmasqRA=1. For all other cases, dnsmasqRA=0.
Code is added to the radvd functions which checks dnsmasqRA and exits if
it is 1.
Code is added to the dnsmasq configuration file if dnsmasqRa=1. If
dhcp-range or dhcp-hosts is specified for IPv6, then enable-ra is added
for stateful (dhcpv6). Otherwise, a special
"dhcp-range=<ipv6-subnet-address>,ra-only" so that the ManagedFlag will
be off in the RA packets for stateless operation.
OK, how does that sound? Everyone comfortable with that?
Another thing is that I plan to add a test such that if the radvd
executable is not valid, the dnsmasqRA=1.
As I was doing this, I also looked through the libvirt.spec file. My,
what a wonderful example of wizardly that is. Anyway, I thought some
updates may be in ortder:
- increase the minimum version for dnsmasq from 2.41 to 2.48.
- why is radvd required for rpmbuild?
- in light of my patch, make radvd an optional runtime requirement. I am
not a spec file expert by any means but there must be a way to not
require radvd if dnsmasq >- 2.63.
