 Thank you for response.

Could you suggest best approach for porting application from 1.0.2 to 1.1.1?
So far I've found good manual which describes required modifications:

The question is whether it describes ALL required modification?

The version of the Linux kernel is almost certainly irrelevant.  OpenSSL
makes minimal demands of the operating system.  Only random number generation
is plausibly something you need to think about.  The getrandom(2) kernel API
was added in Linux 3.17, so you'll need to use /dev/urandom instead.

Otherwise, sockets, threads, ... are all present in Linux even before 3.0.
