Hi, Thorsten here, with a quick preface before the latest report from
regzbot. From my side things seem to look normal right now; in fact
quite a few mainline regression that I've been tracking got resolved in
the past few days (I removed two from the report that are fixed by
changes in the git tags Borislav and Dmitry asked you to pull this
weekend; guess you will merge them later today).
Sadly it seems I still don't get aware of quite a few regressions as
people don't CC the regressions mailing list. :-/ Well, that's life...
BTW, to reduce noise Regzbot now supports putting some regressions on
"back burner" and will not list them in the report, unless there was
recent activity; they are still visible in the web-ui.
I hope to work on better bugzilla.kernel.org integration soon, then
regzbot will show a proper "last activity date" when an issue is only
discussed in a ticket.
Ciao, Thorsten

Hi, this is regzbot, the Linux kernel regression tracking bot.
Currently I'm aware of 23 regressions in linux-mainline. Find the
current status below and the latest on the web:
https://linux-regtracking.leemhuis.info/regzbot/mainline/
Bye bye, hope to see you soon for the next report.

Thanks for your attention, have a nice day!
Regzbot, your hard working Linux kernel regression tracking robot
P.S.: Wanna know more about regzbot or how to use it to track regressions
for your subsystem? Then check out the getting started guide or the
reference documentation:
https://gitlab.com/knurd42/regzbot/-/blob/main/docs/getting_started.md
https://gitlab.com/knurd42/regzbot/-/blob/main/docs/reference.md
The short version: if you see a regression report you want to see
tracked, just send a reply to the report where you Cc
regressions@lists.linux.dev with a line like this:
#regzbot introduced: v5.13..v5.14-rc1
If you want to fix a tracked regression, just do what is expected
anyway: add a 'Link:' tag with the url to the report, e.g.:

Those as expected got merged, great. But I forgot to mention one thing
in my preface: there is a regression introduced in the 5.15 cycle where
I'd like to hear your option, as it's one of those tricky issues that
might need a judgement call, as it's security related.
The culprit here is 76a3c92ec9e0 ("cifs: remove support for NTLM and
weaker authentication algorithms"), which as of now afaics cleanly
reverts in mainline. As the title indicates, it's a change to remove
code in the interest of maintainability and security, but it seems some
people are now unable to access CIFS 1.0 shares on some devices (like
the media player "mede8er med600x3"). For details see:
https://lore.kernel.org/lkml/CAJjP=Bt52AW_w2sKnM=MbckPkH1hevPMJVWm_Wf%2BwThmR72YTg@mail.gmail.com/
[some backstory can also be found in the two bug tickets linked there,
which show the reporter is not the only one that ran into the
regression; see for example
https://bugzilla.kernel.org/show_bug.cgi?id=215375#c13 ]
I recently brought "should this be reverted" up in the discussion and
this is what Ronnie (who authored 76a3c92ec9e0) replied in
https://lore.kernel.org/lkml/CAN05THQbR4d55kx6MEHGcn-iLZKJG1C0vhq19wfo=NrB6q1Apg@mail.gmail.com/

I also asked the reporter if win11 still is able to access the device,
and this is what he replied in
https://lore.kernel.org/lkml/CAJjP=Bus1_ce4vbHXpiou1WrSe8a61U1NzGm4XvN5fYCPGNikA@mail.gmail.com/

Now I'm a bit unsure what the best way forward is here; if you have one
and want to share it, could you please do so in above thread (it's on
LKML, subject is "Possible regression: unable to mount CIFS 1.0 shares
from older machines since 76a3c92ec9e0668e4cd0e9ff1782eb68f61a179c"), as
that where everybody is CCed. tia!
