Subject [jira] [Commented] (HADOOP-12668) Modify HDFS embeded jetty server logic in HttpServer2.java to exclude weak Ciphers through ssl-server.conf
Date Mon, 01 Feb 2016 17:48:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12668?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15126625#comment-15126625
] 

Zhe Zhang commented on HADOOP-12668:
------------------------------------

I added a break point and printed the values in {{availableCiphers}}. I think the main point
of the unit test is to verify that once we add one of the below to {{excludeCiphers}}, they
won't appear in {{availableCiphers}} anymore. Then we know the added config knob is taking
effect.

{code}
0 = "TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA"
1 = "TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA"
2 = "TLS_RSA_WITH_AES_128_CBC_SHA"
3 = "TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA"
4 = "TLS_ECDH_RSA_WITH_AES_128_CBC_SHA"
5 = "TLS_DHE_RSA_WITH_AES_128_CBC_SHA"
6 = "TLS_DHE_DSS_WITH_AES_128_CBC_SHA"
7 = "TLS_ECDHE_ECDSA_WITH_RC4_128_SHA"
8 = "TLS_ECDHE_RSA_WITH_RC4_128_SHA"
9 = "SSL_RSA_WITH_RC4_128_SHA"
10 = "TLS_ECDH_ECDSA_WITH_RC4_128_SHA"
11 = "TLS_ECDH_RSA_WITH_RC4_128_SHA"

> Currently Embeded jetty Server used across all hadoop services is configured through
ssl-server.xml file from their respective configuration section. However, the SSL/TLS protocol
being used for this jetty servers can be downgraded to weak cipher suites. This code changes
aims to add following functionality:
> 1) Add logic in hadoop common (HttpServer2.java and associated interfaces) to spawn jetty
servers with ability to exclude weak cipher suites. I propose we make this though ssl-server.xml
and hence each service can choose to disable specific ciphers.
> 2) Modify DFSUtil.java used by HDFS code to supply new parameter ssl.server.exclude.cipher.list
for hadoop-common code, so it can exclude the ciphers supplied through this key.
