kernel panic caused by kernel update from v5.15.133 to v5.15.146

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hi, developers,

This is Chenglong Tang from the Google Container Optimized OS team. We recently received a kernel panic bug from the customers regarding cifs. 

I sent this email again with more detailed investigation we did these days and also because the previous one was sent to the wrong address.

Here are some steps we did in order to reproduce the issue:

  1. Deploy GKE Cluster with the same version as the customer v1.26.13-gke.1144000
  2. Deploy SMB CSI Driver Daemonset: https://github.com/kubernetes-csi/csi-driver-smb/blob/master/docs/install-csi-driver-v1.12.0.md
  3. Create SMB Server on the same cluster: https://github.com/kubernetes-csi/csi-driver-smb/tree/master/deploy/example/smb-provisioner
  4. Create Pod to create Client to create a PersistentVolume on the Samba Server in (3): https://github.com/kubernetes-csi/csi-driver-smb/blob/master/deploy/example/deployment.yaml
  5. Wait and observe to see if there are any Kernel Panics in VM Instance logs or Node that is running the Client pod goes into NotReady state.

Unfortunately (5) did not occur, therefore we were unable to reproduce locally. I am not sure why in the customer's environment this issue is present.

DS for CSI SMB node is:

image: gcr.io/iaas-gcr-reg-prd-ad3d/vendor/sig-storage/smbplugin:v1.12.0

and CSI SMB Controller

image: gcr.io/iaas-gcr-reg-prd-ad3d/vendor/sig-storage/smbplugin:v1.12.0
image: gcr.io/iaas-gcr-reg-prd-ad3d/vendor/sig-storage/livenessprobe:v2.11.0
image: gcr.io/iaas-gcr-reg-prd-ad3d/vendor/sig-storage/csi-provisioner:v3.6.0

Based on this it looks like this a pretty outdated version of the 

SMB CSI Controller - since 1.12.0 was released Aug 11, 2023

However, our systems should be fault tolerant and not kernel panicking / crashing - we should investigate this as many other customers might run into the same issue.

We are not able to swap to newer versions of kernels(currently in v5.10 and 5.15).


The customer said the problem occurred because of the kernel update from v5.15.133 to v5.15.146.


Here are the recent kernel changes we make in cifs:

Our first diagnosis is that we think the problem might be caused by memory corruption. From the assembly code we can see that

  3f:   55                      push   %rbp

The trapping happened before the call of 0xffffffffd3fb4588 (strcmp) and mov (%rax),%rsi is for the second argument of strcmp. And from the backtrace I posted, we can see that rax is ffffffff00000000, which was corrupted and that caused the segmentation fault.


We checked that it's impossible for cache_cp to be NULL and cache_cp->charset should have a value because load_nfs_default will definitely return a non-NULL value. That's why we believe it should be caused by some changes related to the memory free/allocation that corrupted the static table.


I can't narrow down anymore and am still working on it. Feel free to share thoughts with us.


Best,


Chenglong
