It looks very promising. We had no more problems on the test systems.

Yes, they are.

No, they're not.

I do think so. Please integrated the patches.

Thank you very much.

Best regards,

Frank

Title:
  Oops when Kerberos credentials are invalid

Status in linux package in Ubuntu:
  Incomplete
Status in linux source package in Disco:
  In Progress

Bug description:
  There's a bug in Linux Kernel 5.0 which is triggered by invalid
  credentials when the NFS clients is trying to aquire them via GSSD.
  This affects NFS-Shares that are protected by krb5* security. They
  become unusable until the system is re-booted. The problem is quite
  severe on terminal servers with multiple users - some of them not
  caring about refreshing their kerberos tickets.

  A fix is available here:

  
<https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/net/sunrpc/clnt.c?id=7987b694ade8cc465ce10fb3dceaa614f13ceaf3>
