Hello David, or anyone else affected, Accepted haproxy into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/haproxy/1.8.8-1ubuntu0.5 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

Just with a no change rebuild it would pick that up. [Test Case] * run "haproxy -vv" and check the reported TLS versions to include 1.3 [Regression Potential] * This should be low, the code already runs against the .so of the newer openssl library. This would only make it recognize the newer TLS support. i'd expect more trouble as-is with the somewhat big delta between what it was built against vs what it runs with than afterwards. * [1] and [2] indicate that any config that would have been made for TLSv1.2 [1] would not apply to the v1.3 as it would be configured in [2]. It is good to have no entry for [2] yet as following the defaults of openssl is the safest as that would be updated if new insights/CVEs are known. But this could IMHO be the "regression that I'd expect", one explcitly configured the v1.2 things and once both ends support v1.3 that might be auto-negotiated. One can then set "force-tlsv12" but that is an administrative action [3] * Yet AFAIK this fine grained control [2] for TLSv1.3 only exists in >=1.8.15 [4] and Bionic is on haproxy 1.8.8. So any user of TLSv1.3 in Bionic haproxy would have to stay without that. There are further changes to TLS v1.3 handling enhancements [5] but also fixes [6] which aren't in 1.8.8 in Bionic. So one could say enabling this will enable an inferior TLSv1.3 and one might better not enable it, for an SRU the bar to not break old behavior is intentionally high - I tried to provide as much as possible background, the decision is up to the SRU team.

(If that's not desirable for some reason, then maybe TLSv1.3 should be actively disabled to avoid any surprises in case of a future bug fix release.) --- Output of haproxy -vv with stock package: Built with OpenSSL version : OpenSSL 1.1.0g 2 Nov 2017 Running on OpenSSL version : OpenSSL 1.1.1 11 Sep 2018 (VERSIONS DIFFER!)
