Author: tkreuzer Date: Wed Nov 20 23:50:42 2013 New Revision: 61061 URL: http://svn.reactos.org/svn/reactos?rev=61061&view=rev Log: {NTOSKRNL] Properly implement MmGetSessionById, MmAttachSession, MmDetachSession and MmQuitNextSession. Implement more session cleanup code and make sure a session is not killed while a process is attached to it. There used to be a bug, where removing a process from the session list caused pool corruption, which was because we called MiSessionRemoveProcess twice: once from PspExitThread, when the last thread exited and another time from PspDeleteProcess, when the reaper thread deleted the process object. This was, because the flag that said the process was in a session was not cleared properly. This is now fixed and inserting and removing processes into the session's list works fine. Also protect it properly with a spinlock.
