[Samba] Samba shared folders: file permission bits issue

Dear Samba list,

I set up a samba server on debian. The samba version is 4.2.10, and the server configuration is as follows:

    # Global parameters
            server role = standalone server
            security = USER
            map to guest = Bad User
            obey pam restrictions = Yes
            syslog = 0
            log file = /var/log/samba/log.%m
            max log size = 1000
            dns proxy = No
            panic action = /usr/share/samba/panic-action %d
            idmap config * : backend = tdb

            comment = Opensource Directory
            path = /home/opensrc
            force user = opensrc
            read only = No
            create mask = 0644
            map archive = No

Everything works fine other than the file permission bits under Linux. Windows client mounted the samba opensrc shared folder. When a file is created on the Windows side, its permission is:

    # file: home/opensrc/newfile.txt
    # owner: opensrc
    # group: opensrc

Yet, when the file is edited and saved from Windows side, then the file permission becomes:

    # file: home/opensrc/newfile.txt
    # owner: opensrc
    # group: opensrc

Tried many different options but none works out nicely. Anyone can shed some light on it? Thanks.
