Remove trailing whitespace from all text files
I've used the following command to remove the trailing whitespace for
all tracked text files:

git grep -Il '' | xargs sed -i 's/[ \t]*$//'

CDS / CDNSKEY Child side processing.
* We need a mechanism to say that key should have a cds publish
start/end dates.
* We need a mechanism to say that key should have a cdnskey publish
start/end dates
- update dnssec-settime, dnssec-keygen, dnssec-keyfromlabel
- update K* files
* dnssec-signzone should add cds and/or cdnskey to zone apex iff the
DNSKEY is published and is signing the DNSKEY RRset. CDS and CDNSKEY
records are only removed if there is a deletion date set (implicit on
matching DNSKEY going inactive / unpublished or explicit).
Non-matching CDS and CDNSKEY are removed.
* auto-dnssec maintain should cds and/or cdnskey to zone apex iff the
DNSKEY is published and is signing the DNSKEY RRset. CDS and CDNSKEY
records are only removed if there is a deletion date set (implicit on
matching DNSKEY going inactive / unpublished or explicit).
* UPDATE should check that CDS and CDNSKEY match a active DNSKEY that
is signing the DNSKEY RRset and ignore otherwise. This should be
done after all the update section records have been processed.
? how will this tie in with CDS/CDNSKEY sanity checks? Only on fail?
* UPDATE should remove CDS and CDNSKEY records that match a DNSKEY
that is being removed. This should be done after all the update
section records have been processed.
? how will this tie in with CDS/CDNSKEY sanity checks? Only on fail?
* Zone loading should perform sanity checks on CDS and CDNSKEY
records against the DNSKEY records. This will flow through into
dnssec-checkzone and "dnssec-checkconf -z". ignore/warn/fail
* rndc add the ability to say generate CDS / CDNSKEY along with a key list /
all / all SEP
* rndc add the ability to say remove CDS / CDNSKEY.
* inline zones need to check CDS and CDNSKEY records in the raw zone and
filter non matching.
* CDS and CDNSKEY must be signed by a DNSKEY which matches parent DS record.
This is is different to how non DNSKEY RRsets are usually signed
