[Bug 1822872] Re: Bionic: Luminous radosgw incompatible with libssl1.1

[Dimitri John Ledkov]

In bionic we ship two OpenSSL: 1.0.2 and 1.1.0, both in main with
security support. The latter is getting upgraded from 1.1.0 to 1.1.1.

If ceph in bionic only supports 1.0.2 abi, it should build-depend on
libssl1.0-dev and use that both at build time and runtime.

If cepth in bionic support 1.1.0 abi, it would build-depend on libssl-
dev and use that both at build time and runtime.

libssl1.0 and libssl1.1 are coinstallable ABIs.

  [Test Case]

  1) Generate a self-signed certificate or use whatever existing SSL
  certificate already in place.

  2) From the radosgw node, modify "/etc/ceph/ceph.conf" as follow:
  rgw_frontends = civetweb ssl_port=443 ssl_certificate=/etc/ssl/<CERTIFICATE>

  3) Restart the daemon:
  systemctl restart ceph-radosgw at rgw.`hostname -s`

  4) Look logs:

  5) Look radosgw which should FAILED to start.

  [Original Description]

  Bionic's radosgw package (Version 12.2.11-0ubuntu0.18.04.1 ) can't run
  on Bionic, because the version of civetweb in Luminous is incompatible
  with libssl1.1, but it's built against libssl1.1.

  This has been known about upstream for a while now, and as noted in
  the bug-tracker (https://tracker.ceph.com/issues/20696), it can be
  fixed by building Luminous in an environment that has only libssl1.0
  available (or, in a more invasive manner, by incorporating a newer
  civetweb). A patch is in the tracker.ceph.com issue.
