-Alternativ: Pakete von sernet+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."//
