samba - Mar 2020 - Path length problem?

Hello all,

I am trying to investigate if a path length problem is solvable at all under
linux/samba. To my knowledge path length on w*ndows can be max 32767 chars and
filename length max 255 chars.
But linux (and POSIX) tell me that the maximum path length is 4096. So I would
expect that copying some deep tree from w*ndows to a samba server might be a
problem. And indeed we already saw such a problem linked with nextcloud.
Is there any personal experience about this out there?

Yes, this might be a problem with a sufficiently deeply
nested NTFS filesystem tree.

The only solution would be to use a Samba VFS backend
with a larger PATH_MAX value and re-compile Samba after
making sure you're using a new PATH_MAX definition.

Hope this helps.
