+From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] backport: mgr/dashboard: simplify authentication protocol
+
+This is a backport of https://github.com/ceph/ceph/pull/54710 which
+fixes the Ceph Dashboard not being able to launch on Ceph Reef running
+on Debian Bookworm.
+
+This is achieved by removing the dependency on `PyJWT` (Python) and thus
+transitively also removing the dependency on `cryptography` (Python).
+For more information, see the original pull request.
+
+Note that the Ceph Dashboard still cannot be used if TLS is activated,
+because `pyOpenSSL` is used to verify certs during launch. Disabling
+TLS via `ceph config set mgr mgr/dashboard/ssl false` and using e.g.
+a reverse proxy can be used as a workaround.
+
+A separate patch is required to allow the dashboard to run with TLS
+enabled.
+
+Fixes: https://forum.proxmox.com/threads/ceph-warning-post-upgrade-to-v8.129371

+Subject: [PATCH] mgr/dashboard: remove ability to create and check TLS
+ key/cert pairs
+
+In order to avoid running into PyO3-related issues [0] with PyOpenSSL,
+the ability to create self-signed certs is disabled - the command
+`ceph dashboard create-self-signed-cert` is made to always return an
+error.
+
+The command's error message contains the manual steps the user may
+follow in order to set the certificate themselves, as well as a link
+to the Ceph Dashboard documentation regarding TLS support. [1]
+
+Furthermore, the check on start-up, that verifies that the configured
+key/cert pair actually match, is also removed. This means that users
+need to ensure themselves that the correct pair is supplied -
+otherwise their browser will complain.
+
+These changes allow the dashboard to launch with TLS enabled again.

[pve-devel] [PATCH quincy-stable-8 ceph 2/2] patch: fix `ceph dashboard` subcommand becoming unavailable on crash

[Max Carrara]

Adapt the patch that originally disabled certain TLS checks during the
dashboard's startup and fixes the `ceph dashboard` subcommand becoming
unavailable if the dashboard crashes during that time.

This is achieved by re-implementing certain checks and also re-raising
any other unforeseen exceptions that occur in regards to TLS as one of
Ceph's internal exception types, which are then handled by the
dashboard itself. This is akin to how these cases were handled
originally.

 Subject: [PATCH] mgr/dashboard: remove ability to create and check TLS
  key/cert pairs
 
@@ -18,6 +18,17 @@ key/cert pair actually match, is also removed. This means that users
 need to ensure themselves that the correct pair is supplied -
 otherwise their browser will complain.
 
+Other checks unrelated to the verification of keypairs are preserved,
+such as checking for the cert's and key's existence on the filesystem.
+
+`ssl.SSLError`s that occur during startup are re-raised with the
+additional information they contain as `ServerConfigException`s, as
+the dashboard handles these in its startup loop. Other exceptions are
+re-raised as well. Otherwise, the dashboard will irrecoverably crash,
+which also causes the `ceph dashboard` subcommand to stop working
+altogether, even if one of its sub-subcommands are unrelated to the
+dashboard itself.

 These changes allow the dashboard to launch with TLS enabled again.
