Windows用户可以覆盖CIFS / SMB共享上的文件的NFSv4 / Solaris A

我想创建一个具有以下目标的共享目录：用户(比如alice)应该能够创建和修改文件,但不能删除它们.还应该防止创建子目录.应允许读访问权限.

我尝试过以下ACL,它基本上可以工作：

/usr/bin/chmod A=
user:root:rwxpdDaARWcCos:fd-----:allow,    # root has full access
user:alice:rwx---a-R-c--s:-------:allow,   # dir: create files,read everything
user:alice:rwxp--aARWc--s:f-i----:allow    # files: wpAW is needed for full file write access,everything is only inherited to files
/pool/share

但是,如果alice在Windows资源管理器中查看新添加文件的“安全”选项卡,则她可以授予自己完全访问权限并在之后删除该文件,即使她没有Co权限也是如此.

如何解释这种行为？我怎样才能更改它以便无法修改ACL？

编辑：ls的输出似乎正常：

# /usr/bin/ls -v
total 1
-rwx------+  1 alice staff          3 2016-03-21 test.txt
    0:user:root:read_data/write_data/append_data/read_xattr/write_xattr
        /execute/delete_child/read_attributes/write_attributes/delete
        /read_acl/write_acl/write_owner/synchronize:inherited:allow
    1:user:alice:read_data/write_data/append_data/read_xattr
        /write_xattr/execute/read_attributes/write_attributes/read_acl
        /synchronize:inherited:allow

# /usr/bin/ls -V
total 1
-rwx------+  1 alice staff          3 2016-03-21 test.txt
    user:root:rwxpdDaARWcCos:------I:allow
    user:alice:rwxp--aARWc--s:------I:allow

输出目录本身的ls：

# /usr/bin/ls -Vd
drwx------+  3 root     root           4 2016-03-21 .
 user:root:rwxpdDaARWcCos:fd-----:allow
user:alice:rwx---a-R-c--s:-------:allow
user:alice:rwxp--aARWc--s:f-i----:allow

# /usr/bin/ls -vd
drwx------+  3 root     root           4 2016-03-21 .
    0:user:root:list_directory/read_data/add_file/write_data
        /add_subdirectory/append_data/read_xattr/write_xattr/execute
        /delete_child/read_attributes/write_attributes/delete/read_acl
        /write_acl/write_owner/synchronize:file_inherit/dir_inherit:allow
    1:user:alice:list_directory/read_data/add_file/write_data
        /read_xattr/execute/read_attributes/read_acl/synchronize:allow
    2:user:alice:list_directory/read_data/add_file/write_data
        /add_subdirectory/append_data/read_xattr/write_xattr/execute
        /read_attributes/write_attributes/read_acl/synchronize
        :file_inherit/inherit_only:allow

共享的文件系统是ZFS.最有趣的非默认属性如下：

NAME        PROPERTY        VALUE          SOURCE
pool/share  type            filesystem     -
pool/share  compression     lz4            inherited from pool
pool/share  atime           off            local
pool/share  aclmode         restricted     local
pool/share  aclinherit      passthrough    local
pool/share  version         5              -
pool/share  utf8only        on             -
pool/share  normalization   formD          -
pool/share  casesensitivity insensitive    -
pool/share  nbmand          on             local
pool/share  sharesmb        name=testshare local

CIFS共享权限设置为允许每个人完全访问权限,因此只应应用文件权限.

更新：

This thread与我的问题非常相似,虽然将/pool/share/.zfs/shares/testshare中的ACL减少到每个人的modify_set(或拒绝用户特定的删除权限)的解决方案在我的情况下似乎不起作用我不喜欢不知道为什么.
