Bug Description

[Impact]
The NFS client's access cache becomes stale due to the user's group membership changing on the server after the user has already logged in on the client.
The access cache only expires if either NFS_INO_INVALID_ACCESS flag is on or timeout (without delegation).
Adding a user to a group in the NFS server will not cause any file attributes to change.
The client will encounter permission errors until other file attributes are changed or the memory cache is dropped.

[Fix]

The access cache shall be cleared once the user logs out and logs back in again.

0eb43812c0270ee3d005ff32f91f7d0a6c4943af NFS: Clear the file access cache upon login
029085b8949f5d269ae2bbd14915407dd0c7f902 NFS: Judge the file access cache's timestamp in rcu path
5e9a7b9c2ea18551759833146a181b14835bfe39 NFS: Fix up a sparse warning

[Test Plan]
1.[client side] testuser is not part of testgroup
  testuser@kinetic:~$ ls -ld /mnt/private/
  drwxrwx--- 2 root testgroup 4096 Nov 24 08:23 /mnt/private/
  testuser@kinetic:~$ mktemp -p /mnt/private/
  mktemp: failed to create file via template
  ‘/mnt/private/tmp.XXXXXXXXXX’: Permission denied
2.[server side] add testuser into testgroup, which has access to folder
  root@kinetic:~$ usermod -aG testgroup testuser &&
  echo `date +'%s'` > /proc/net/rpc/auth.unix.gid/flush
3.[client side] create a file again but still fail
  testuser@kinetic:~$ mktemp -p /mnt/private/
  mktemp: failed to create file via template
  ‘/mnt/private/tmp.XXXXXXXXXX’: Permission denied

[Where problems could occur]
The fix will apply upstream commits, so the regression can be considered as low.

Eirik Rye (striata) wrote (last edit ):

This patch appears to have caused a massive (thousandfold) increase in NFS ACCESS operations.

Tested with Ubuntu 20.04 and these kernels:

  5.4.0-144-generic
  5.15.0-67-generic

Downgrading to either 5.4.0-139-generic or 5.15.0-60-generic resolves the issue again.

One busy server using NFS went from an average of about 14 ACCESS operations per second to around 33 000 operations per second. This completely overwhelmed the NFS servers, making them practically unusable.

Hello @striata I have seen the same issue and I have spend days tracking down the issue. I have Two in a load balanced pair, one with the kernel version 5.15.0-1031the other with 5.15.0-1028. The server with 5.15.0-1031 shows NFS ops in the 2-5000 for the same work the other server does with 2-50.

I'm going to put a hold on updates until there is some resolution for this. If there is anything I can do to help let me know.

Khaled El Mously (kmously) wrote (last edit ):

The kernels that are currently in -proposed should have resolved this issue. Kernel versions:

 5.4.0-154.171 (focal)
 5.15.0-77.84 (jammy)

The new NFS behaviour has been made to be opt-in only using the "nfs_fasc=1" modprobe option. So default behaviour should be back to normal unless this option is used.

The new behaviour was submitted under LP #2022098
