There is a regression discussed in bugzilla I'd like to see tracked, to ensure it's not forgotten. Quoting a few parts of the report: > After 5.15.0, I'm unable to mount a CIFS 1.0 share from a media player which I cannot update (vendor no longer provides updates). > > Original issue is logged here: https://bugs.gentoo.org/821895, with the most interesting bits probably being: > Ok, 2.5 hours of bisecting later and I can confirm that the culprit is > > [76a3c92ec9e0668e4cd0e9ff1782eb68f61a179c] cifs: remove support for NTLM and weaker authentication algorithms > > The commit before works fine, this commit prevents me from mounting the smb shares on my mede8er 600x 3d. #regzbot introduced: 76a3c92ec9e0668e #regzbot link: https://bugzilla.kernel.org/show_bug.cgi?id=215375 #regzbot link: https://bugs.gentoo.org/821895 I'm not CCing any of the developers for now, looks like they are handling it in bugzilla. And yes, starting a extra thread for this is a hack hate myself, but I need some workaround for tracking due to the distributed nature of bug reporting with various different bug trackers in use (reminder: bugzilla.kernel.org is not the only one used by kernel developers). Ciao, Thorsten
