       appending "allow_read/write" entry didn't update internal "allow_read"







1817
 
       and "allow_write" entries. As a result, attempt to open(O_RDWR) succeeds







1818
 
       but open(O_RDONLY) and open(O_WRONLY) fail.







1819
 
 







1820
 
       Workaround is to write an entry twice when newly appending that entry.







1821
 
       If written twice, internal  "allow_read" and "allow_write" entries







1822
 
       are updated.
