[Impact]
* OpenSSL 1.1.1 is an LTS release upstream, which will continue to
receive security support for much longer than 1.1.0 series will.
* OpenSSL 1.1.1 comes with support for TLS v1.3 which is expected to be
rapidly adopted due to increased set of supported hashes & algoes, as
well as improved handshake [re-]negotiation.
* OpenSSL 1.1.1 comes with improved hw-acceleration capabilities.
* OpenSSL 1.1.1 is ABI/API compatible with 1.1.0, however some software
is sensitive to the negotiation handshake and may either need
patches/improvements or clamp-down to maximum v1.2.
[Test Case]
* Rebuild all reverse dependencies
* Execute autopkg tests for all of them
* Clamp down to TLS v1.2 software that does not support TLS v1.3 (e.g.
mongodb)
* Backport TLS v1.3 support patches, where applicable
[Regression Potential]
* Connectivity interop is the biggest issues which will be unavoidable
with introducing TLS v1.3. However, tests on cosmic demonstrate that
curl/nginx/google-chrome/mozilla-firefox connect and negotiate TLS v1.3
without issues.
* Mitigation of discovered connectivity issues will be possible by
clamping down to TLS v1.2 in either server-side or client-side software
or by backporting relevant support fixes

- * Most common connectivity issues so far:
- - client verifies SNI in TLSv1.3 mode, yet client doesn't set hostname.
Solution is client change to set hostname, or to clamp down the client to
TLSv1.2.

- - session negotiation is different in TLSv1.3, existing client code
+ - session negotiation is different in TLSv1.3, existing client code
may fail to create/negotiate/resume session. Clients need to learn how
to use session callback.

* TLS v1.3 support in NSS is expected to make it to 18.04 via security
updates
* TLS v1.3 support in GnuTLS is expected to be available in 19.04
* Test OpenSSL is being prepared in
