[jira] [Commented] (KUDU-1926) Disable SSL session renegotiation

    [ https://issues.apache.org/jira/browse/KUDU-1926?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16238163#comment-16238163 ] 

Alexey Serbin commented on KUDU-1926:
-------------------------------------

There is SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION for that (appeared in 0.9.7 version), but we don't set it in the TLS context yet.

> SSL renegotiation has had a couple of CVEs in the past. We should figure out if it's easy to disable it and do so, since we don't expect to use it in KRPC.
> (it may already be the case that it's disabled by virtue of us not handling SSL_WANT_READ return from ssl_write, and SSL_WANT_WRITE from ssl_read).
