With the latest ksmbd from the next branch I have an issue with wife's Wind= ows=20 10 laptop while copying/removing files from the network share. On her clien= t it=20 looks like copy operation (server -> laptop) reaches 99% and then stalls, a= nd=20 on the server side there's this in the kernel log: ``` ksmbd: Unsupported addition info: 0xf) ksmbd: Unsupported addition info: 0x20) ``` repeated multiple times. I must note that in fact the file gets copied to h= er=20 laptop, but Windows copy dialog just hangs. Any idea what it could be and how to avoid it? This also happened before (I= 'm=20 a pretty early ksmbd adopter), but I'm reporting it just now because I na= =EFvely=20 hoped it would be fixed automagically :). This never happened to me with=20 userspace Samba though. This is my smb.conf: ``` [global] workgroup =3D KANAPKA server string =3D ksmbd server %v netbios name =3D defiant valid users =3D __guest [Shared] valid users =3D __guest path =3D /mnt/shared force user =3D _shared force group =3D _shared browsable =3D no writeable =3D yes veto files =3D /lost+found/ ``` Appreciate your time and looking forward to your response. Thanks. =2D-=20 Oleksandr Natalenko (post-factum)
