Anything using CBC mode - ECC is just fine.

Which is a bad idea because CBC is still a very common cipher mode.

They can't agree on a common ciphersuite. The reason is that the server does not support any CBC mode. Which is a bad idea because CBC is still a very common cipher mode.

If I understand correctly, this is exactly the same problem that the one we encountered some time ago in the code dealing with fetching keys from HTTP (--fetch-keys), and that we fixed with this patch.

fwiw, the bug looks like it's in send_request in ks-engine-hkp.c, which re-uses the http_session object without re-initializing its tls_session member.

thanks for the triage, @werner!

It is fixed in master branch of the repo.

Applied.

New gpg-error.m4 detects gpgrt-config, too.
And configure supplies --libdir when it invokes gpgrt-config.
For other *.m4 (libassuan, ksba, libgcrypt, ntbtls), it is possible for them to check GPGRT_CONFIG to use gpgrt-config if any.
For npth.m4, it can do that too, with no hard dependency to libgpg-error.

A bit tricky, but this would be good to use gpgrt-config by gpg-error.m4.
I say "tricky", because its name is gpg-error.m4 but it configure GPGRT_CONFIG to access to GPG_ERROR_CONFIG.

It might be good idea to provide libgcrypt.pc in libgcrypt 1.8.x for forward compatibility with libgpg-error 1.33.

Well, I changed my mind. Use of new gpgrt-config requires software update to introduce gpgrt.m4 and update of configure.ac to switch gpgrt from gpg-error, in standard way.
That's too much this time. It's good to defer this change.

OK, I'll change to use gpgrt-config, along with requiring newer version of libgpg-error.

May I suggest to use a (new) gpgrt-config instead of the current name libgpg-error-config. The long term plan is to change the name of the library.

This is the dependency graph:

Done for gpgme.

Done for npth.

Thanks for the report.
Fixed in master.

Add the tag of npth (forgotten).

Done for libassuan

Thanks for the list

Here is the list:

• libgcrypt
• libassuan
• ntbtls
• gpgme : autogen.sh is ready
• npth
