+Michael Tokarev <mjt@tls.msk.ru> schrieb am 20.7.2023 auf der Debian LTS Mailingliste:
+//"It come to my attention that a discussion is happening about samba
+and LTS (and the same applies to oldstable too).
+The thing is: samba packages in bullseye and before, in my opinion,
+are hopeless.  I know it because I know the state of debian packaging
+it was.  For years (for a few debian releases), samba maintenance was
+more on auto-pilot. Most changes were made by applying a minimal change,
+not the right change. The result was.. horrible.
+Now, the Samba team basically re-designed whole VFS layer in 4.16, to
+fix a few serious issues with symlinks.  This is not backportable to
+anything, and it changes quite big portion of the codebase, so subsequent
+fixes even in seemingly unrelated areas don't apply anymore (not all
+of them ofc).
+Upstream stopped supporting 4.13 (bullseye) version of samba even before
+bullseye release iirc.  There were numerous alternative samba repositories
+all around the world to plug the gap between debian-provided samba and
+actual samba.
+There are numerous other security issues, compatibility issues with
+previous windows releases, and other stuff which basically makes samba
+in bullseye (already, not to mention buster!) basically unusable.
+Trying to fix an issue or two there will work. This particular issue
+with Jul-23 windows10/11 update is trivial to fix, the same change
+applies (with minimal context fix) to 4.7 version of samba too.
+But I urge not doing this. This will bring false sense of security.
+People will think samba in buster or bullseye is worth to keep since
+it is being "supported", - it is not due to other numerous issues.
+It is like with old crypto, - you fix a buffer overflow in some DES
+implementation, but it does not mean DES can be used in 2023.
+If there's a need for samba in buster, it can be fixed. See for
+example my repository at http://www.corpit.ru/mjt/packages/samba/ -
+it provides amd64 binaries of all current samba packages on actual
+Debian and Ubuntu releases, - I spent quite some time to ensure it
+all works fine on different environments and the original debian
+packages can be built on older debian releases and on various
+ubuntu releases.  This currently does not include buster, but it
+is kinda trivial to fix.  My repository happens to become quite
+popular (by the amount of downloads, amount of screaming once I
+turned it off for 5 minutes for a reboot, and amount of questions
+I received after the Jul-23 windows update), - so something like
+this is needed (or was, anyway, for older releases).
+Buster and bullseye versions of samba are not supported.  Please
+don't use band-aid on a dead horse."//
