Unusable v6 interfaces are now detected on Windows and then not used.

Ping.

There is a growing bit of popular lore in the GnuPG community that "when keyserver operations fail, you solve that problem with killall dirmngr." I believe this suggestion is potentially damaging (the long-running daemon may be in the middle of operations for a client that you don't know about), but i suspect it is circulating as advice because it resolves the situation outlined in this ticket. For whatever ephemeral reason, dirmngr gets stuck, and fails to notice that this situation has resolved itself.

I'm aware of you releasing an RC for comments, and i apologize for not catching this particular case earlier. As you know from T4607, i was even advocating for it. i didn't understand the full implications of the "import-then-clean" approach at the time, and was thinking it would only apply to the incoming material, not the stored material.

The code has comments why we do a first clean_key on the imported keyblock.

i've merged a variant of rGbe99eec2b105eb5f8e3759147ae351dcc40560ad into the GnuPG packaging in debian unstable as of version 2.2.17-3 to avoid the risks of data loss and signature verification failures. I'll revert it if i see the concern addressed upstream.

that pseudocode is strange to me -- it looks like you have (two) duplicate calls to clean_key (imported_keyblock) (though maybe i just don't know what .... means in this pseudocode).

You are partly right. I missed that we also do clean the original keyblock while updating a key. The code is

I think dropping import-clean from the default keyserver options is the right way to go. It is not clear what additional benefit import-clean provides given that we are already using self-sigs-only. And the idea of non-additive behavior to the local keyring when pulling from a keyserver is a deeply surprising change for multiple users i've talked to.

Ah, that makes sense, good catch. Seems this is just an issue of documentation, then.

We should put it of the agenda od the Brussesl summit in 3 weeks. I have a few ideas what we can do in gpg.

Given the recent problems with the keyservers, I expect that the keyserver feature will go away anyway and thus I do not think we will put any more effort into this. Thus I re-tag this as gpg 2.3.

If we only need it for backward compatibility, then the configuration in gpg.conf should *not* be overriding the preferred, forward-looking form of the configuration (in dirmngr.conf). If it is low priority to fix this, then there will be a generation of GnuPG users and toolchains which deliberately configure the value in gpg.conf instead of dirmngr.conf because they'll know that's the more robust way to do it.

We need --keyserver in gpg for just one reason: backward compatibility.

thanks for fixing that error message, @werner. As @Valodim points out in discusson about hagrid, a gpg.conf keyserver option (deprecated according to the documentation) overrides the dirmngr.conf keyserver option (not deprecated according to the documentation.

I doubt that we are going to implement this.

Thanks

I removed this specialized error message. Thanks for reporting.

This is particularly bad for users who have manually specified a given keyserver in dirmngr.conf, because even a transient failure in that keyserver will prevent them from any future keyserver requests until dirmngr decides that the "death" has worn off.

HTTP/1.1 spec, RFC 7230, Section 5.4, paragraph 2:
https://tools.ietf.org/html/rfc7230#section-5.4

Please be so kind and point me to the specs stating that you should put the IP address into Host:

It's up to GPG to send the Host header that shows the user's intent.

So in short you want:

1. Allow to specify a keyserver by IP without any DNS lookups.
2. When connecting via IP use the IP address for Host:.

There is a solution for it:

So, the keyserver operator had thrown in a hockeypuck server in the pool, causing this.. While the keyserver remains in the exclude list until confirmation it has been resolved, that explains the behavior and it has been made clear that separate software needs to use different names in the future.
