Error description

  • Application utilizes sync-to-osthread in order to push a user
    identity onto the operating system thread.  The application also
    accesses a native dll. When the classloader is searching the
    application for the native dll, a security violation occurs
    because the HFS was searched under the identity of the user, and
    not the identity of the application server.
    
    An example violation may look like the following:
    
    ---------
    
    ICH408I USER(USER   ) GROUP(SOMGROUP ) NAME(   )
      /WebSphere/Base/AppServer/profiles/default/installedApps/cell

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server for z/OS V6.1.0 and V8.0             *
    ****************************************************************
    * PROBLEM DESCRIPTION: When the "sync to OS thread" function   *
    *                      is enabled, native library loads can    *
    *                      fail when using application class       *
    *                      loaders                                 *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When "sync to OS thread" is enabled on z/OS, the server ID must
    be put on the thread stack before filesystem operations are
    allowed to take place.  This was not occurring for native
    library loads in the WAS application class loaders, and HFS
    violations could result.
    

Problem conclusion

  • The server identity push was included in the WAS application
    class loader's findLibrary method.
    
    APAR PM40962 is currently targeted for inclusion in Service
    Level (Fix Pack) 6.1.0.43 of WebSphere Application Server
    V6.1 and Fix Pack 8.0.0.2 of WebSphere Application Server V8.0.
    
    The fix will also be delivered as sysrouted APAR PM47302 in
    Fix Pack 7.0.0.21 of WebSphere Application Server V7.0 for z/OS.
