6 May 2022: Wouter
- Merge PR #209: IXFR out
This adds IXFR out functionality to NSD. NSD can copy IXFRs from
upstream to downstream clients, or create IXFRs from zonefiles.
The options store-ixfr: yes and create-ixfr: yes can be used to
turn this on. Default is turned off. The options ixfr-number and
ixfr-size can be used to tune the number of IXFR transfers and
total data size stored. This is configured per zone, the IXFRs
are served to the hosts that are allowed to perform zone transfers.
And if TSIG is configured, signed with the same key. The content
is stored to file if a zonefile is configured for the zone, in
the zonefile.ixfr and zonefile.ixfr.2, .. files. They contain
readable text format. The number of IXFRs is num.rixfr in
statistics output, also per zone if per zone statistics are enabled.
If offline, nsd-checkzone -i can create ixfr files.
NSD already supports requesting IXFRs, this addition allows NSD
to serve IXFR transfers to clients.
NSD stops responding with NOTIMPL to IXFR requests, also for zones
that do not have IXFR enabled. The clients gets a full zone reply
or a status reply if the serial is up to date.
