Bug description:
[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
[Test cases for the python updates]
python3.7 is a preview in bionic as a non-supported/non-default
version of python3. Passing it's own autopkgtests is sufficient
validation for python3.7. It includes a point release update, with
OpenSSL 1.1.1 compat and features.
python3.6 not only has OpenSSL 1.1.1 compat and features patches, but
also includes a point release update to 3.6.8. It has been part of the
full-archive rebuild and regression analysis. Autopkgtests were
triggered for python3.6 and python3-defaults with regressions already
fixed in the individual packages as appropriate.
python2.7 has the update from .15~rc1 to .15 final, with OpenSSL 1.1.1
compat only. It has been part of the full-archive rebuild and
regression analysis. Autopkgtests were triggered for python2.7 and
python-defaults with regressions already fixed in the individual
packages as appropriate.
The archive rebuilds done, were commulative with OpenJDK 11, OpenSSL 1.1.1
and python point releases as seen in:

[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
* Notable changes are listed here
https://wiki.openssl.org/index.php/TLS1.3
* 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
may fail to create/negotiate/resume session. Clients need to learn how
to use session callback.
* This update bundles python 3.6 and 3.7 point releases
[Other Info]
* Previous FFe for OpenSSL in 18.10 is at
https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/1793092
* 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

[Autopkgtest Regressions]
dovecot/armhf - flakey
libnet-ssleay-perl - awaiting sru accept into proposed of
libnet-ssleay-perl and libio-socket-ssl-perl due to fixes and
versioned breaks.
linux* - rebuild testcases passes (for some edge flavours the build
fails in non-ssl portions of the build), ubuntu-regression-suite
testcase fails for a few variants but should have been skipped (in
progress to be fixed in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1823056)
openvswitch/i386 - extremely flakey, errors out or fails mostly
