> The current permission checker of #MountTableStoreImpl is not very restrict.
> In some case, any user could add/update/remove MountTableEntry without the
> expected permission checking.
> The following code segment try to check permission when operate
> MountTableEntry, however mountTable object is from Client/RouterAdmin
> {{MountTable mountTable = request.getEntry();}}, and user could pass any mode
> which could bypass the permission checker.
> {code:java}
> public void checkPermission(MountTable mountTable, FsAction access)
> throws AccessControlException {
> if (isSuperUser()) {
> return;
> }
> FsPermission mode = mountTable.getMode();
> if (getUser().equals(mountTable.getOwnerName())
> && mode.getUserAction().implies(access)) {
> return;
> }
> if (isMemberOfGroup(mountTable.getGroupName())
> && mode.getGroupAction().implies(access)) {
> return;
> }
> if (!getUser().equals(mountTable.getOwnerName())
> && !isMemberOfGroup(mountTable.getGroupName())
> && mode.getOtherAction().implies(access)) {
> return;
> }
> throw new AccessControlException(
> "Permission denied while accessing mount table "
> + mountTable.getSourcePath()
> + ": user " + getUser() + " does not have " + access.toString()
> + " permissions.");
> }
> {code}
> I just propose revoke WRITE MountTableEntry privilege to super user only.
