Subject [jira] [Updated] (HADOOP-14597) Native compilation broken with OpenSSL-1.1.0 because EVP_CIPHER_CTX has been made opaque
Date Tue, 27 Jun 2017 20:18:01 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-14597?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ravi Prakash updated HADOOP-14597:
----------------------------------
    Attachment: HADOOP-14597.00.patch

I'm not sure this is the right patch, but it lets the compilation continue. I'm using functions
defined here https://github.com/openssl/openssl/blob/master/crypto/evp/evp_lib.c#L196. I don't
know what the intent of making the internals opaque is, if I can get to the same flags using
this method. This leads me to believe this patch is probably not what the openssl devs intended.
Anyone know anything about this?

> One of the primary differences between master (OpenSSL 1.1.0) and the 1.0.2 version is
that many types have been made opaque, i.e. applications are no longer allowed to look inside
the internals of the structures
