samba - Jun 2019 - SAMBA AD VFS:Recycle bad permissions

Hello dancers,
I upgraded SAMBA to version 4.9 in three little companies. Then we have 
found an error with permissions, on shared discs where is VFS:recycle 
enabled, new created folders seem to be ok, but new files are writable 
only from owner. Getfacl gets back mask r-- so effective rights are 
changed. Shared discs without VFS:recycle work fine, and if I disable 
VFS:recycle on shared folders, where it is active, permissions are 
working again fine. I have one SAMBA server with version 4.8 where 
VFS:recyle is enabled too, and everything is working well. Two of 4.9 
servers have XFS filesystem, one has EXT4. Before upgrade I used samba 
4.8 and before 4.6. and I had no problem with VFS:recycle and permisions 
until today.

best regards
bB

Good morning,
I have tried upgrade SAMBA to version 4.10.4 and my error still exists. 
New created file has mask limited perrmisions if VFS:recycle module is 
activated for share. If module is off, rights for new files works 
corectly. I have it on 3 servers with Samba 4.10 and 4.9, one server 
withj 4.8 works properly.

any ideas?
bB

There were changes made to the VFS ABI with the release of Samba 4.9.0, 
perhaps it is these that are causing your problem ?

It might help if you post your smb.conf.
