Great, many thx!

Totally fine with me and yeah, a bit esoteric. But when somebody bisects
and report a problem (in this case: Boris) that already fixed in next
for a few days, my mind yells "what a waste or energy, this could have
been prevented by mainlining the fix a bit more quickly" -- that's why I
brought it up.

Ahh, great.

BTW, there is one thing that still bugs me: every few weeks there is yet
somebody new[1] complaining about the removal of support for NTLM and
weaker authentication algorithms from cifs some time ago in
76a3c92ec9e0. The situation[2] was improved slightly in 2f6f19c7aaad
("cifs: fix regression in very old smb1 mounts"), but it seems some
users of Apple Time Capsules or some Epson printer/scanner still can't
access their devices which apparently still work fine in Windows and

Yes, the issue is tricky, as there are security implications here and we
have nobody that tests this, as you pointed out [3]. Is there
nevertheless something somebody committed could do? Would we even be
willing to add that support back in, in case someone commits to maintain
and regularly test that codepath?

Ciao, Thorsten
