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

[Eric Desrochers]

Here's my thought process about this:

----
Package "2.2.11-0ubuntu0.18.04.1" uses: civetweb version "1.8" 

Confirmation: 
src/civetweb/include/civetweb.h:#define CIVETWEB_VERSION "1.8" 
-----

While I'm sure that downgrading libssl as 'Build-Depends' works for that
particular case, I am concerned about what downgrading libssl may
introduce as potential regression in Ceph since Bionic Ceph has been
build/tested against libssl 1.1. We would need to be very careful if we
go that route IMHO.

For the moment, I see 2 options: 
1) Downgrade libssl Build-Depends from 1.1 to 1.0 in order to make civetweb works, but possibly risk to introduce (or not) potential Ceph regression/ Ceph undesired behaviour change/ ... (tbd)
2) Upgrade civetweb to adapt to 1.1 by identifying the right commits/patchset : 

>From what I read so far, it seems like there might be good potential candidates:
https://github.com/civetweb/civetweb/pull/384/commits 
https://github.com/civetweb/civetweb/commit/adac9c916fa892ec5edce7b565803f1e62d304a2 
https://github.com/civetweb/civetweb/commit/5d83900fd29fb6fa1cd604676cb0562dc984dcc9 

3) Upgrade ceph' source pkg's civetweb version to a version where libssl
is fully supported. (if doable/compatible/...)

Currently, option 2) is definitely my favourite approach.

I don't fully ignore option 1), but I would prefer spending time to
investigate how feasible the backport of libssl 1.1 adaptation/fixes
patchset into 1.8 goes and/or evaluate an upgrade from v1.8 to
<RECENT_VERSION_INCLUDING_WHAT_IT_NEEDS> of civetweb into Ceph.

And of course, I would appreciate to have the Openstack team opinion
about my chain of thought here.

Eric

Title:
  Bionic: Luminous radosgw incompatible with libssl1.1

Status in ceph package in Ubuntu:
  New
Status in ceph source package in Bionic:
  New

Bug 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.
