Description of problem:
ldns-signzone in ldns-1.5.1 is broken in such a way that it silently generates invalid zone data. An unpleasant surprise when I moved my nameserver from a el4 box (where I had compiled my own updated ldns) to a vanilla el5 + epel.
According to DNSSEC spec all conforming dnsservers returns SERVFAIL on queries for data in the zones signed with ldns-1.5.1. so this is kind of serious.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. generate two pairs of keys
2. sign a zone with those keys
the keytag of the key signing key is by one which results in a mismatch between the DNSKEY records in the signed zone and the DS records in the parent zone
matching keytag integers of DNSKEY and DS records, functioning zone validation
With an update to the current 1.6.1 release this problem is solved (no changes to the .spec file is needed except for the version bump). Some investigation points to changes in r2878 that landed somewehere before 1.6.0.
ldns-1.6.1-2.el5 made it's appearance in a yum update today. I hope that 'CURRENTRELEASE' is the right choice for closing this
