I've reviewed the packaging changes; they mostly look good, I have only
a few questions/comments:
The added Build-Depends:
liblttng-ust-dev,
liblttng-ust1t64,
are duplicative; liblttng-ust-dev already Depends on liblttng-ust1t64.
Is there a reason for explicitly pulling liblttng-ust1t64 in?
The debian/rules change:
- extraopts += -DWITH_LTTNG=OFF -DWITH_EMBEDDED=OFF
+ extraopts += -DWITH_LTTNG=ON -DWITH_EMBEDDED=ON
changes both the WITH_LTTNG and WITH_EMBEDDED settings. (This appears to
be harmless because WITH_EMBEDDED appears to be an option the build
system no longer recognises)
Finally, the Noble upload has a weird diff from the other uploads:

However, this is not a change from the status-quo - this is not a diff
introduced by this upload. It might be worth working out why the Noble
version of this patch is slightly different, though.

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 19.2.2 https://ceph.io/en/news/blog/2025/v19-2-2-squid-released/
* ceph 19.2.3 https://ceph.io/en/news/blog/2025/v19-2-3-squid-released/
Notable changes:
* This fixes a silent RGW data loss regression when CopyObject is used to copy an object onto itself. The regression results in objects past the original 4mb head object being added to the garbage collection queue and deleted permanently, and are not recoverable.
* LTTNG has been enabled for easier tracing and debugging.
Key differences from upstream:
* libnbd has been disabled from the build system. libnbd is in universe in Ubuntu, and cannot be a dependency for 19.2.3.
* On questing, adjustments had to be made to build with boost1.88. On plucky and noble, these adjustments have been removed to build with standard boost 1.83 and 1.82.
* python-cryptography uses PyO3 to call some rust based bcrypt and TLS functions, and has problems being called in parallel and in sub-interpreters, necessary for ceph-dashboard to work correctly. This was fixed by backporting:
commit 717d0a6f3530ad3e07f4423002810327b2addcf1
From: "Paulo E. Castro" <pecastro at wormholenet.com>
Date: Sat, 5 Apr 2025 21:47:55 +0100
Subject: pybind/mgr: Hack around the 'ImportError: PyO3 modules
may only be initialized once per interpreter process' issue.
Link: https://github.com/ceph/ceph/commit/7094a5a44d90e705141dbae9739e6c0835bf7ce3

* Noble also receives the bugfix for hardened CFLAGS for python modules. See https://bugs.launchpad.net/ubuntu/+source/ceph/+bug/2078244
[Test Case]
This SRU will run all functional tests with the packages in 'proposed'
for every Ceph charm maintained by Canonical's Ceph team, so that
there's a higher chance of catching bugs associated with any Ceph
component.
(mruffell to lmlogiudice:
* can you add details of what ceph-charms will be run?
* will you do any upgrade testing from 19.2.1 to 19.2.3?
* will you test LTTNG being enabled? How? What will you trace to check it works?
* is it possible to verify that the data loss regression has been fixed?
)
[Regression Potential]
ceph is a critical package as it underpins large scale data storage
and integrity checking, and care must be taken to not introduce any
data loss regressions. ceph also is a common backing store for
OpenStack virtual machines through ceph-rbd, and care must be taken to
not break any API or ABI compatibility with current OpenStack
releases.
In order to mitigate the regression potential, the results of the
aforementioned tests will be attached to this bug.
