Libunbound openssl error - 0.11.0.0 release version

[dEBRUYNE-1]

A few users have been reporting these "errors" on Linux 64-bit (using the latest release, Helium Hydra):

[1504816717] libunbound[25519:0] info: warning: unsupported algorithm for trust anchor . DS IN

[1504816717] libunbound[25519:0] warning: trust anchor . has no supported algorithms, the anchor is ignored (check if you need to upgrade unbound and openssl)

As far as I can tell, it doesn't inhibit them from syncing or using the daemon.

This prevents DNSSEC verification, but it's apparently not done well in the first place anyway. This looks like an OpenSSL which was compiled with SHA1 (or a cmake bug which causes USE_SHA1 to be undefined when building unbound).

Possibly some relevant information here.

The format is a DNS resource record on one line, DS or DNSKEY.

If I call ub_ctx_add_ta() with the string you have there, the root
anchor with a \n after it, it works fine.

The warning is printed if you try to load an unsupported trust anchor,
this behaviour has changed in recent releases, dealing with loading
trust anchors with unknown algorithms, to support root key rollover
schemes more thoroughly.

However, the string you give has supported algorithms. I do not
understand either why you get this error. Are you loading a different
string? (for instance with an ECDSA algorithm and the user has old
OpenSSL with no ECDSA support).

Or have you compiled unbound without sha256 support? Not even sure if
that is possible and I think that needs configure options to do it,
but then this message would appear.

Note the hard coded anchor will get you in trouble with the root key
rollover that is talked about in public forums. You need to have some
sort of update process (f.e. using your software update).

Best regards, Wouter

I am afraid that it does see to stop us syncing or even accessing the wallet at all. MY balance is 0.00000 at the moment.

Can you file new bugs separately please, or this is going to be really confusing. One of the txes in the pool seems to be corrupt.

[moneromooo-monero]

Might be fixed by #2996

[moneromooo-monero]

Can someone who had that problem confirm whether this is fixed ?

[salim-b]

it's fixed for me (Ubuntu 16.04 LTS) 🙂

Thanks
