Bug#1069102: linux-image-6.1.0-20-amd64 and cifs mount problem on some folders which get hidden on shares
Package: src:linux
Version: 6.1.85-1
Severity: important
Dear Maintainer,
* What led up to the situation?
kernel update from version 6.1.0-18 to 6.1.0-20
* What exactly did you do (or not do) that was effective (or
ineffective)?
out system mounted a samba share via autofs (cifs) and we tried to
access some files and directories
* What was the outcome of this action?
the mount point of our share is /srv/samba/shares/company and the
directory it/MIJ had another directory "digitale kommunikation" which
did not shop up on the computer which mounted the samba share. before
the kernel update it did and when we renamed the file to
"digitale_kommunikation" or to "digitalo kommunikation" we could see it.
in the syslog we found the following messages:
CIFS: VFS: directory entry name would overflow frame end of buf ...
we could move that direcotry into another directory and it was useable,
we created another directory it/abc and created the "digitale
kommunikation" inside and it was hidden again. after switching back to
kernel 6.1.0-20 everything was ok.
upgrade to kernel 6.5.0-0.deb12.4-amd64 package was ok too.
* What outcome did you expect instead?
we expected to just see the "digitale kommunikation" directory as before.
