vtls: stop offering alpn http/1.1 for http2-prior-knowledge
- For HTTPS if http2-prior-knowledge is set then only offer h2 (HTTP/2)
alpn to the server for protocol negotiation.
Prior to this change both HTTP/2 ("h2") and HTTP/1.1 ("http/1.1") were
offered for ALPN when http2-prior-knowledge was set.
CURL_HTTP_VERSION_2_PRIOR_KNOWLEDGE (tool: --http2-prior-knowledge) is
meant to send non-TLS HTTP requests HTTP/2 when it is known the server
supports them. However when HTTPS is used then it attempts to first
negotiate the connection with ALPN. In that case the user likely does
not want to offer http/1.1 to the server as an acceptable protocol.
Setting SSLHonorCipherOrder to on means it honors the server cipher
order. From the documentation: "When choosing a cipher during an SSLv3
or TLSv1 handshake, normally the client's preference is used. If this
directive is enabled, the server's preference will be used instead."
Also the commit inhibits test_17_07_ssl_ciphers. The test tries to
tests if all the ciphers specified, and only those, are properly set
in curl. For that to work we need have cases where some or all ciphers
do no intersect with the cipher-set of the server. We need to be able
to assert a failed connection based on a cipher set mismatch.
That is why a restricted set of ciphers is used on the server. This
set is so chosen that it contains the well known most secure ciphers.
Except with the slower aes256 variant intentionally left out, to be
able to test above described.
As test_17_07_ssl_ciphers is currently the only test that tests the
functioning of the --ciphers and --tls13-ciphers options, it is
important that its coverage is as good as possible.
