[Pkg-samba-maint] Bug#1050527: /sbin/mount.cifs: [105129.516313] CIFS: VFS: \\10.27.27.26 Error -32 sending data on socket to server

[CIFS errors when mounting shares on BookWorm]

Package: cifs-utils
Version: 2:7.0-2
Severity: normal
File: /sbin/mount.cifs
X-Debbugs-Cc: schmoe at brokensolstice.com

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

Trying to transfer large files from one sever to another via cifs.  This problem only manifests when the linux box is pushing a file to the windows server -- never happens when the windows server is initiating.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I mounted the window share, and tried copying a file to that mounted share.


   * What was the outcome of this action?

It hangs indefinitely... only a reboot will get me out.

I have tried a number of mount options including switching versions, using the handle cache and not using it... it doesn't matter.


It is worth noting that when I booted this Debian server to Clonzilla live media (Clonezilla-Live 2.8.1-12-amd64), this problem did NOT occur. The transfer went smoothly, and did not hang.  It worked beautifully.  It is only under Bookworm that this seems to happen.

   * What outcome did you expect instead?

I expected the file to transfer, and then give me my prompt back.  (Not hang)
