+Subject: [PATCH] crypto: ensure we use a predictable TLS priority setting
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The TLS test cert generation relies on a fixed set of algorithms that are
+only usable under GNUTLS' default priority setting. When building QEMU
+with a custom distro specific priority setting, this can cause the TLS
+tests to fail. By forcing the tests to always use "NORMAL" priority we
+can make them more robust.
