Hello Knot DNS users, CZ.NIC has released Knot DNS 2.7.6! This version mainly fixes a very old bug relating pending zone events upon server reload or configuration commit. If you don't use zone journal, please check if it exists and possibly drop it. It can be a consequence of a small regression introduced in the previous version. I'm sorry for that! Changelog: https://gitlab.labs.nic.cz/knot/knot-dns/tags/v2.7.6 Source code: https://secure.nic.cz/files/knot-dns/knot-2.7.6.tar.xz https://secure.nic.cz/files/knot-dns/knot-2.7.6.tar.xz.asc Documentation: https://www.knot-dns.cz/docs/2.7/html Support: https://www.knot-dns.cz/support Regards, Daniel

zonefile-load: difference

by Volker Janzen

Hi, I want to use Ansible to deploy zone files to my Knot signer (hidden master). The zone files should be generated from the Ansible playbook data and will not contain any DNSSEC related information, just SOA, NS, A, AAAA, TXT and MX records. I'd like to use Knot DNSSEC auto-signing. I can stop the Knot process before deploying new zone files. I use zonefile-load: difference in this case, as of the DNSKEY / CDNSKEY / CDS data should not be replaced with something new. Should this work for me, or is there anything I miss or is there even a better option? Kind regards, Volker

knot group in a FreeBSD jail -- Permission Denied to Knotc and Python API

by Rick van Rein

Hi, I'm working on a registry for +31 ENUM, using Knot DNS 2.6.8. The intention is to trigger the Python API from PostgreSQL database views. The postgres user, though added to the knot group and granted rw- on all of /var/db/knot/* and the knotd socket, cannot do thinkgs like conf-read through the Python API or knotc. This is where root and the postgres user diverge: 84630 knotc CALL open(0x7fffffffe100,0x100022<O_RDWR|O_EXLOCK|O_CLOEXEC>) 84630 knotc NAMI "/tmp/SEMDMDBrXFzK!_#un)" 84630 knotc RET open 6 84630 knotc CALL fstat(0x6,0x7fffffffe068) 84630 knotc STRU struct stat {dev=4261341516, ino=125942, mode=0100660, nlink=1, uid=0, gid=0, rdev=4294967295, atime=1545172776.416579000, mtime=1545182138.348328000, ctime=1545182138.348328000, birthtime=1545172776.416478000, size=16, blksize=4096, blocks=2, flags=0x800 } That's root. uid=0 and gid=0 for the /tmp/SENDMDB... file. But now: 84649 knotc CALL open(0x7fffffffe0f0,0x100022<O_RDWR|O_EXLOCK|O_CLOEXEC>) 84649 knotc NAMI "/tmp/SEMDMDBrXFzK!_#un)" 84649 knotc RET open -1 errno 13 Permission denied That's user postgres, even though it is in the knot group. It seems to see the file but have no access, probably due to uid=0, gid=0. Note that matching name. --> What is this file it is trying to open, and is it always mapped to uid=0,gid=0, even if the user running "knotc conf-read" is not root? Could this be a FreeBSD things, or a jail thing? Any advise is welcome! Thanks! -Rick

Re: [knot-dns-users] knot group in a FreeBSD jail -- Permission Denied to Knotc and Python API

by Daniel Salzman

I don't think the Makefile is wrong. If you call knotc with an explicit control socket specification, no configuration file is loaded because it's not needed. So there is an issue with the configuration access. But I don't understand why knotd is not affected? You could also test using configuration database.

Question on KSK rollover

Hi all, one of my zones made a ZSK rollover yesterday. I had an some recursive resolvers validation errors at different times.

The actual authorative nameservers get the zone from Bind with IFXR or AXFR. AXFR is used for distribution to a anycast nameserver pair. When looking at the ZSK rollover timing, I notice that after two hours Knot stopped signing with the old ZSK. Does this make sense? The last event before the rollover has been this resining: Dec 4 18:16:48 a knotd[9924]: info: [voja.de.] DNSSEC, signing zone Dec 4 18:16:48 a knotd[9924]: info: [voja.de.] DNSSEC, key, tag 53800, algorithm RSASHA256, KSK, public, ready, active Dec 4 18:16:48 a knotd[9924]: info: [voja.de.] DNSSEC, key, tag 38188, algorithm RSASHA256, public, active Dec 4 18:16:48 a knotd[9924]: info: [voja.de.] DNSSEC, signing started Dec 4 18:16:48 a knotd[9924]: info: [voja.de.] DNSSEC, successfully signed Dec 4 18:16:48 a knotd[9924]: info: [voja.de.] DNSSEC, next signing at 2018-12-06T17:16:48 Is it possible that this is an issue with a propagation-delay that is too low (default value applies).

OK, thanks. Just making sure I was not missing something obvious. -----Original Message----- From: "libor.peltan" [libor.peltan(a)nic.cz] Date: 11/29/2018 04:33 AM To: knot-dns-users(a)lists.nic.cz Subject: Re: [knot-dns-users] Key sizes with ECDSA Hi Full Name, indeed, this is not possible. The ECC and EDD algorithm families always stick to one key size for any algorithm. You can't have your KSK and ZSK with different algorithms. On the other hand, this is no big deal. Those algorithms are considered safe enough even with small keys, so you can choose just e.g. ECDSA256 and profit from having small signatures. You can also think of using single-type signing scheme.

This works fine for RSA. Now imagine that I want to establish a policy with ECC keys for both KSKs and ZSKs. However, I might want for the KSKs to be 384-bit keys, and for the ZSKs to be 256-bit keys. Can a policy be created in Knot to do so? It would seem that, given that the algorithm specification for NIST elliptic curves includes both the curve and digest data, the key size specifications do not apply here - i.e. both KSKs and ZSKs will necessarily use the same curve, and therefore the same key size.
