Hi Frank, Thanks for the update. Let me know how the test kernel goes when users are on the system.
I looked into your stack trace and found the below link: https://lore.kernel.org/lkml/[email protected]/T/ I'm sure you have probably found it too when researching the bug, and the commit needed to fix it. Can you try running the reproducer? > OK, I think I found something that triggers this fault. This happens > when certain local users try to stat a file or directory on an nfs > mount. Presumably these UIDs do not have appropriate permissions on > the server but I'm not sure exactly (I do not control the server). > > I can reproduce the oops with a command like this: > > # su -s/bin/sh -c 'stat /path/to/nfs/file' problematic_user > > which oopes every time (and SIGKILLs the stat command). Otherwise, let me know how the test kernel goes when opened up to users.
