Author: ion Date: Sat Dec 30 01:17:29 2006 New Revision: 25240 URL: http://svn.reactos.org/svn/reactos?rev=25240&view=rev Log: - Fix OB_SECURITY_METHOD prototype, callers, and implementors. - Add call to SeOpenObjectAuditAlarm in ObCheckObjectAccess. - Start adding Ob Callout validation on checked builds. For now only done around security functions. - Set *MemoryAllocated to FALSE in ObGetObjectSecurity early on to avoid inconcistent state if the callback failed. - Implement new XP function ObSetSecurityObjectByPointer and simplify NtSetSecurityObject by making it use it. - More Win 2003 SecurityDescriptor Cache functions to sdcache instead of obsecure.c.

[ion] 25238: - Fix critical bugs in exception handling: Unwinding was completely broken, using the wrong SEH protector to detect collided unwinding. The correct protector itself also had a broken check. - Fix architectural bug in the entire TrapFrame<->Context conversion system and Ring Privilege Transitions (Inter-ring and intra-ring) which was lacking proper sanitation and validation of segments, flags and debug registers. Among other things, IOPL is now respected, CS is not KGDT_R0_CODE | RPL

Author: ion Date: Fri Dec 29 21:49:00 2006 New Revision: 25238 URL: http://svn.reactos.org/svn/reactos?rev=25238&view=rev Log: - Fix critical bugs in exception handling: Unwinding was completely broken, using the wrong SEH protector to detect collided unwinding. The correct protector itself also had a broken check. - Fix architectural bug in the entire TrapFrame<->Context conversion system and Ring Privilege Transitions (Inter-ring and intra-ring) which was lacking proper sanitation and validation of segments, flags and debug registers. Among other things, IOPL is now respected, CS is not KGDT_R0_CODE | RPL_MASK anymore, and the GPF code is now properly being called. This completely fixes exception handling being totally broken and crashing firefox installer, mirc, and other applications. - Rewrite the page fault handler base code in assembly instead of relying on a broken C routine. Detect VDM, V8086, detecting expected/normal fault in ExpInterlockedPopEntrySList and faults in the system handler code. Rewrite MmAccessFault to be the main function that calls out to other sub-fault functions, and use the same prototype as NT. - Fix the KGDT boot table to have proper granularity and big flags, and extend it to 256 entries. - Create proper thread context in RtlInitializeContext and cleanup Rtl Thread routines. - Remove all int3 and breakpoints from trap handlers, and replace them with a much better "UNHANDLED_PATH" macro which freezes the system, beeps, and displays a message with the line of code that's unhandled. This is to clearly tell the user that something is unhandled, instead of nesting infinite exceptions due to the int3. - Fix a bug in INT_PROLOG. - Sanitize EFLAGS and Code Segments in KeContextToTrapFrame and KeTrapFrameToContext. - Implement KiUpdateDr7 and KiRecordDr7 as well as DR_MASK and other DR-validation macros and functions to protect against DR-vulnerabilites as well as to properly account for each active hardware breakpoint in a per-thread fashion by using the dispatcher header. - Allow CR0_EM when running in a VDM. - Fix FPU/NPX Register handling in KeContextToTrapFrame and KeTrapFrameToContext, and also speed it up by manual copying instead of a memory move. - Properly give IOPL 3 to user-mode threads if they requested it. - Detect GPF during GPF. - Detect pagefault with a trap-frame spread over two or more pages and nested. - Properly sanitize and set correct trap frame in KiInitailizeUserApc. - Return STATUS_ACCESS_VIOLATION during page faults instead of STATUS_UNSUCESSFUL. - Fix assert in VdmSwapContext, as well as Code Selector check which was broken. - Fix delayed object deletion (ObDeferDeleteObject) and the Ob Repear Routine and list. - Update Kernel Fun. - BUGBUG: Temporaily hack VMWare to detection to always detect VMWare.
