New Fileset Attribute to Ignore Special Owning Group and Everyone Permissions

To allow applications outside our control to function properly when storing data in Spectrum Scale file and directory owners must be granted implicit control and have the ability to run chmod against files and directories they own. Depending on the ACLs set at the top of project trees this can allow users to give away more access to data then is desired by the project administrators. Ignoring the group and other mode bits when doing authorization checks as is done with the AFS filesystem would solve this concern.

    Thank you for submitting this enhancement request. This is not in the Storage Scale Roadmap in the foreseeable future.

    A directory has the following acls:
    #owner:igb
    #group:users
    special:owner:rwxc:FileInherit:DirInherit
    special:group:----:FileInherit:DirInherit
    special:everyone:----:FileInherit:DirInherit
    group:eclipz_admin:rwxc:FileInherit:DirInherit
    group:eclipz_sf5_members:r-x-:FileInherit:DirInherit
    user:igb:rwx-:FileInherit:DirInherit

    I now run:

    chmod 755 .

    The new acls are:
    #owner:igb
    #group:users
    special:owner:rwx-
    special:group:r-x-
    special:everyone:r-x-
    special:owner:rwxc:FileInherit:DirInherit:InheritOnly
    special:group:----:FileInherit:DirInherit:InheritOnly
    special:everyone:----:FileInherit:DirInherit:InheritOnly|
    group:eclipz_admin:rwxc:FileInherit:DirInherit
    group:eclipz_sf5_members:r-x-:FileInherit:DirInherit
    user:igb:rwx-:FileInherit:DirInherit

    Now any group: or user: acls we had to control access become irrelevant. There are many applications that calls the chmod command. If we prevent users from running the chmod command on the fileset, such applications will fail. This feature request will allow them to run successfully while maintaining the security implememented through any existing group: and/or user: acls
