[Bug 2100625] Re: [SRU] ceph 17.2.9

[Luciano Lo Giudice]

Hello Matthew,

> Why is the exporter module being enabled now?

We didn't need the exporter until now, but some metrics that we look
into were recently moved into it (Ceph daemon perf counters, to be more
specific), and so some alert rules weren't working any more. Thus the
need to re-enable the ceph-exporter.

> Does the exporter module get packaged, and where?

Not to my knowledge. There was never a *.install file for it under
`debian/`. AFAIK, it's an internal binary not meant to be directly
called by users.

> Does the exporter module work, and what is the testcase?

It's meant to expose performance counters via the Prometheus endpoint.
We have tested that this works via the PPA, yes.

> Does any other ceph components use the vendored boost library?

No, only the ceph-exporter.

> Does the Security Team know we are using the vendored boost library
instead of the distro packaged one?

We haven't notified them of this. Since Ceph vendors in the same
libraries that are shipped with our distros, we didn't think it was
necessary.

> Can the exporter module be patched to build with the distro packaged
boost library instead?

Not on Jammy. The exporter uses Boost.JSON, which wasn't available back
then (Hence why it was disabled in the first place).

> When it gets linked, it gets linked to system boost libraries:

Right, the only vendored library that it's using is Boost.JSON, which is
a header-only library, so no linking. The rest of the Boost stuff comes
from the system.

Let me know if you need anything else,

Luciano.

Bug description:
  [Impact]
  This release fixes several bugs. We would like to make sure all of our users have access to these improvements.

  The update contains the following package updates:

     * ceph 17.2.9
     * Race condition prevention when printing Inode in ll_sync_inode (by Ponnuvel Palaniyappan)

  [Test Case]
  The following SRU process was followed:

  https://documentation.ubuntu.com/sru/en/latest/reference/exception-
  OpenStack-Updates/

  In order to avoid regression of existing users, the OpenStack team
  will run their continuous integration test against the packages that
  are in -proposed. A successful run of all available tests will be
  required before the proposed packages can be let into -updates.

  The OpenStack team will be in charge of attaching the output summary
  of the executed tests. The OpenStack team members will not mark
  ‘verification-done’ until this has happened.

  [Regression Potential]
  In order to mitigate the regression potential, the results of the aforementioned tests will be attached to this bug.
