Subject: cifs.upcall broken with cifs-utils 6.13
Date: Tue, 20 Apr 2021 18:05:20 +0200	[thread overview]
Message-ID: <a01d5d22-5990-c00d-bc2a-582d2585ea69@alexanderkoch.net> (raw)

The recent release of cifs-utils 6.13, more precisely e461afd8cf (which, 
to my understanding, is a fix for CVE-2021-20208) makes attempts of 
mounting CIFS shares with krb5 fail for me:

     cifs.upcall[78171]: switch_to_process_ns: setns() failed for cgroup
     cifs.upcall[78171]: unable to switch to process namespace: 
Operation not permitted


Can anyone tell me if this is a packaging/configuration issue (Arch in 
my case) or a bug?

Full mount log can be found in [1], along with a confirmation of the 
observed behaviour from another user.

Thanks!


Best regards,

Alex
