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 /Application.ear/WebApplication.war/WEB-INF/classes CL(DIRSRCH ) FID(00028BCE000202950000000000000000) INSUFFICIENT AUTHORITY TO LSTAT ACCESS INTENT(--X) ACCESS ALLOWED(OTHER ---) EFFECTIVE UID(0000000001) EFFECTIVE GID(0000000100) ICH408I USER(USER ) GROUP(SOMGROUP ) NAME( ) /WebSphere/Base/AppServer/profiles/default/installedApps/ce ll/Application.ear/WebApplication.war/WEB-INF/lib/Utility.jar CL(DIRSRCH ) FID(00028BCE000202950000000000000000) INSUFFICIENT AUTHORITY TO LSTAT ACCESS INTENT(--X) ACCESS ALLOWED(OTHER ---) EFFECTIVE UID(0000000001) EFFECTIVE GID(0000000100) CH408I USER(USER ) GROUP(SOMGROUP ) NAME( ) /WebSphere/Base/AppServer/profiles/default/installedApps/ce ll/Application.ear/WebApplication.war/WEB-INF/lib/Utility.jar CL(DIRSRCH ) FID(00028BCE000202950000000000000000) INSUFFICIENT AUTHORITY TO LSTAT ACCESS INTENT(--X) ACCESS ALLOWED(OTHER ---) EFFECTIVE UID(0000000001) EFFECTIVE GID(0000000100)

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server for z/OS V7.0 * **************************************************************** * 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 PM47302 is currently targeted for inclusion in Service Level (Fix Pack) 7.0.0.21 of WebSphere Application Server V7.0. Please refer to URL: //www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack availability.
