* Security: Tighten DynamicLinker*, NativeLibrary and DynamicLibraryBundle ↵Sven Gothel2013-06-214-27/+63
| | | | | | | | | | | | | | | | | | | | | | access (2) - Completes 23341a2df2d2ea36784a16fa1db8bc7385351a12 - Replace 'DynamicLinker' interface w/ well documented one - All DynamicLinker methods are now considered secure, i.e.: - open/lookup and close utilize reference counting on handle via a hash map. - lookupSymbol(..) and close(..) impl. validate the passed library handle whether it's retrieved via open*. This is the fast path, not that expensive. - lookupSymbolGlobal(..) performs Check acccess of 'new RuntimePermission("loadLibrary.*")' if SecurityManager is installed. This is the slow path. - DynamicLibraryBundleInfo now reflects the security requirements, i.e. whether priviledged access is needed.

* Bug 752: Review Code Vulnerabilities (Permission Checks of new exposed code ↵Sven Gothel2013-06-114-24/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and privileged access) This review focuses on how we perform permission checks, or better - do we circumvent some assuming full privileges ? Some native methods do need extra permission validation, i.e. loading native libraries. Further more AccessController.doPrivileged(..) shall not cover generic code exposing a critical feature to the user. Further more .. we should rely on the SecuritManager, i.e. AccessControlContext's 'checkPermission(Permission)' code to comply w/ fine grained permission access. It is also possible to have full permission w/o having any certificates (-> policy file). +++ We remove implicit AccessController.doPrivileged(..) from within our trusted code for generic methods, like Property access, temp. files. +++ SecurityUtil: - Remove 'getCommonAccessControlContext(Class<?> clz)', which returned a local AccessControlContext for later restriction if the passed class contains all certificates as the 'trusted' GlueGen class has. - Simply expose convenient permission check methods relying on SecurityManager / AccessControlContext. PropertyAccess: - 'protected static void addTrustedPrefix(..)' requires AllPermissions if SecurityManager is installed. - Remove implicit doPrivileged(..) triggered by passed AccessControlContext instance, only leave it for trusted prefixes. IOUtil: - Remove all doPrivileged(..) - Elevation shall be performed by caller. DynamicLinker: - 'public long openLibraryLocal(..)' and 'public long openLibraryGlobal(..)' may throw SecurityException, if a SecurityManager is installed and the dyn. link permission is not granted in the calling code. Implemented in their respective Unix, OSX and Windows manifestation. Caller has to elevate privileges via 'doPrivileged(..) {}' ! +++ Tests: - Property access - File access - Native library loading Manual Applet test (unsigned, but w/ SecurityManager and policy file): > gluegen/test/applet Applet has been tested w/ signed JAR w/ Firefox and Java7 on GNU/Linux as well. Manual Application test (unsigned, but w/ SecurityManager and policy file): com.jogamp.junit.sec.TestSecIOUtil01 - Run w/ SecurityManager and policy file: - gluegen/scripts/runtest-secmgr.sh - Run w/o SecurityManager: - gluegen/scripts/runtest.sh

| | | | | | | | | | | | | | May break GCJ/ECJ .. needs to be revised. - Adding JAVA_6 in PlatformPropsImpl - Buffers.isDirect() chooses fast-path iff JAVA_6, otherwise using reflection (GCJ/ECJ) - Adding JAVA_6 info in VersionUtil - API doc: Refine JAVA_SE and JAVA_6 spec. TODO: In case GCJ etc is unable to compile the JAVA_6 code even though it uses a static condition (probably not), We have to wrap isStatic in an own class, one for JAVA_6 and one for <= 1.5. This will be a good exercise for further issues we may have w/ Java <= 1.5.
