Bug description:
[Impact]
* OpenSSL 1.1.1 performs SNI hostname verification, therefore
hostname SSL context option must be set when establishing the
connection, otherwise, validation of SNI certificates fail and thus
resulting in lack of connectivity.
[Test Case]
* use python-boto to connect to an SNI tls protected host, e.g. GCE
google storage using legacy .boto
[Regression Potential]
* change is compatible with pythons/openssl versions shipped in bionic/cosmic-release
* change is from upstream / tested in debian & disco
* change improves security, and is compatible with deployed servers out there
* hosts with certificates not matching their actual hostname will remain invalid/untrusted
[Additional info]
To install python & openssl 1.1.1 on Bionic you may enable and use the below silo, which will then exhibit the enforcement of SNI hostname verification.
