[Pdns-dev] IPv6 - Notify for Master

[Marcel Pennewiß]

Hi,

we're testing PowerDNS (built from SVN) as Master with dualstack. As 
with IPv4 PowerDNS notifies each nameserver listed in NS resource records - 
also the master. For IPv4 this works flawless and notification list will 
rectified as expected. For IPv6 this seems not to work correct.

Being neither a C++ pro nor knowing PowerDNS-source fully in detail, patch 
attached is a "works for me"-solution. 

removeIf will be called with IP+Port as parameter, which is "[IPv6-
address]:Port" in IPv6 and "IPv4-address:Port" in IPv4. removeIf splits this 
parameter on ":" which certainly go wrong on IPv6.

Best Regards,
Marcel

IPv4 (works):
> pdns[27482]: Queued notification of domain 'example.org' to 78.47.xx.x
> ...
> pdns[27482]: Received NOTIFY for example.org from 78.47.xx.x but slave 
support is disabled in the configuration
> pdns[27482]: Received unsuccessful notification report for 'example.org' from 
78.47.xx.x:53, rcode: 4
> pdns[27482]: Removed from notification list: 'example.org' to 78.47.xx.x:53

IPv6 (did not work):
> pdns[27482]: Queued notification of domain 'example.org' to 
2a01:4f8:120:xxxx:x::53
> ...
> pdns[27482]: Received NOTIFY for example.org from 2a01:4f8:120:xxxx:x::53 
but slave support is disabled in the configuration
> pdns[27482]: Received NOTIFY for example.org from 2a01:4f8:120:xxxx:x::53 
but slave support is disabled in the configuration
> pdns[27482]: Received unsuccessful notification report for 'example.org' from 
[2a01:4f8:120:xxxx:x::53]:53, rcode: 4
> pdns[27482]: Received spurious notify answer for 'example.org' from 
[2a01:4f8:120:xxxx:x::53]:53
> pdns[27482]: Received NOTIFY for example.org from 2a01:4f8:120:xxxx:x::53 
but slave support is disabled in the configuration
> pdns[27482]: Received unsuccessful notification report for 'example.org' from 
[2a01:4f8:120:xxxx:x::53]:53, rcode: 4
> pdns[27482]: Received spurious notify answer for 'example.org' from 
[2a01:4f8:120:xxxx:x::53]:53


IPv6 (after Patch):
> pdns[9513]: Queued notification of domain 'example.org' to 
2a01:4f8:120:xxxx:x::53
> ...
> pdns[9513]: Received NOTIFY for example.org from 2a01:4f8:120:xxxx:x::53 but 
slave support is disabled in the configuration
> pdns[9513]: Received unsuccessful notification report for 'example.org' from 
[2a01:4f8:120:xxxx:x::53]:53, rcode: 4
> pdns[9513]: Removed from notification list: 'example.org' to 
[2a01:4f8:120:xxxx:x::53]:53
