Hi,
I think I spoke too soon. I removed 'noserverino' options from all my cifs mounts yesterday and u/remounted them. From last night syslog I can still
find the "directory entry name would overflow frame end of buf" entries.
I have options like this in my fstab:
//mercury/backups /mnt/backups cifs credentials=/etc/smbcredentials,uid=kari,gid=kari,_netdev,dir_mode=0775,file_mode=0775,noperm,vers=3.0 0 0
Regards,
Kari

Hi,
I can confirm that removing the 'noserverino' mount option fixed the problem for me. Unfortunately, I don't have suitable environment at the moment for testing kernel-fixes...
Best regads,
Kari

Can you confirm you are seeing the issue only if mounting with using 'noserverino' mount option? Would you be in the position of building a kernel with a commit reverted and verify the issue is gone with it? If you follow https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#id-1.6.6.4 with the attached patch, you should be able to get a kernel image to test with. Regards, Salvatore |
