Elytron + TLSv1.1 + wrap attribute to false results in empty reply from server

    Details

    • Steps to Reproduce:
      Hide
      1. Unzip and start EAP ./bin/standalone.sh
      2. Configure Elytron using steps in this link:
        keytool -genkeypair -alias localhost -keyalg RSA -keysize 1024 -validity 365 -keystore standalone/configuration/keystore.jks -dname "CN=localhost" -keypass secret -storepass secret
        
        /subsystem=elytron/key-store=httpsKS:add(path=keystore.jks,relative-to=jboss.server.config.dir,credential-reference={clear-text=secret},type=JKS)
        /subsystem=elytron/key-managers=httpsKM:add(key-store=httpsKS,algorithm="SunX509",credential-reference={clear-text=secret})
        /subsystem=elytron/server-ssl-context=httpsSSC:add(key-managers=httpsKM,protocols=["TLSv1.1"])
        /subsystem=undertow/server=default-server/https-listener=https:undefine-attribute(name=security-realm)
        /subsystem=undertow/server=default-server/https-listener=https:write-attribute(name=ssl-context,value=httpsSSC)
        /subsystem=elytron/server-ssl-context=httpsSSC:write-attribute(name=wrap,value=false)
        reload
        

        Note that TLSv1.1 or older must be used, TLSv1.2 seems to be working.

      3. Perform HTTPS request (h2 protocol offerred) to server and see ERR_EMPTY_RESPONSE error from Chrome or curl: (52) Empty reply from server

      Description

      Setup EAP with Elytron, utilizing TLSv1.1 or older. Then set 'wrap' attribute of 'server-ssl-context' to false and perform HTTPS request that offers also h2 protocol to server. There is ERR_EMPTY_RESPONSE error from Chrome or curl: (52) Empty reply from server from curl. When I set DEBUG logging level, I can see following log messages after curl command

      curl -v -k https://localhost:8443

      When I perform request that does not offer h2 protocol, it seems ok and correct response is returned from the server:

      curl -v --http1.1 -k https://localhost:8443
      

      Also when 'wrap' attribute in 'server-ssl-context' is set to true, then all requests to server works just fine (this time also those that offers h2 protocol).

      Probably server tries to utilize h2 protocol as client offered it but as TLSv1.1 or lower is configured this is sentenced to fail (h2 requires TLSv1.2 at least).

      Expected behaviour: HTTPS request from client returns correct response even when 'wrap' attribute in 'server-ssl-context' is set to 'false' and TLSv1.1 or lower is utilized even when client offers h2 protocol to server in request.
