ksmb crash on linux 6.5.3-arch1-1

[mcirsta]

I've noticed that ksmb was not working and found the attached logs in dmesg.

Let me know if additional info is needed though I am not sure how exactly this occurred. I did delete some files on the samba file system though.

Another crash using the exact same configuration and this one for sure occurred while deleting something.

Could you please share how to reproduce this issue ?

1. share your ksmbd.conf
2. do you use mainline ksmbd or github ksmbd ?
3. Is there testcase to reproduce it ? or Can you describe how to reproduce ?
4. what is local filesystem of share directory ? ext4 ?

What is samba file system ? smbclient ? or cifs.ko

1. cat /etc/ksmbd/smb.conf
   [global]
   netbios name = SMBD
   server = SMBD
   browseable = yes
   server string = MiniPC
   workgroup = WORKGROUP
   [extdisk]
   path = /mnt/extdisk
   guest ok = yes
   writable = yes
   browseable = yes

2. Whatever is shipped with the latest Arch kernel : 6.5.5-arch1-1

3. Not really , it doesn't occur every time from what I can tell but the problems happen when deleting the files through the latest version of this Android app called NovaVideoPlayer. After several consecutive deletions the crash in the kernel module would occur

4. It's an external HDD mounted as ntfs-3g:

UUID=70B08D67B08D351E /mnt/extdisk ntfs-3g defaults,uid=1000,gid=1000 0 0

As for the client it's whatever this NovaVideoPlayer uses.

I will try a bit more to see if I can consistently reproduce it when deleting files. One other thing to mention is that they are large files, sometimes even 50-60 GB so one delete operation might not finish before another is requested.
