MSVC on 32-bit windows is an exception. There, C++ - * exceptions are dealt with using Windows' Structured Exception Handling - * (SEH). - * - * SEH is implemented as a singly linked list of <function*, prev*> nodes. The - * head of this list is stored in the Thread Information Block, which itself - * is pointed to from the FS register. It's the first field in the structure, - * or offset 0, so we can access it using assembly FS:[0], or the compiler - * intrinsics and field offset information from the headers (as we do below). - * Somewhat unusually, the tail of the list doesn't have prev == NULL, it has - * prev == 0xFFFFFFFF. - * - * SEH was designed for C, and traditionally uses the MSVC compiler - * intrinsincs __try{}/__except{}. It is also utilized for C++ exceptions by - * MSVC; there, every throw of a C++ exception raises a SEH error with the - * ExceptionCode 0xE06D7363; the SEH handler list is then traversed to - * deal with the exception. - * - * If the SEH list is corrupt, then when a C++ exception is thrown the program - * will abruptly exit with exit code 1. This does not use std::terminate(), so - * std::set_terminate() is useless to debug this. - * - * The SEH list is closely tied to the call stack; entering a function that - * uses __try{} or most C++ functions will push a new handler onto the front - * of the list. Returning from the function will remove the handler. Saving - * and restoring the head node of the SEH list (FS:[0]) per-greenlet is NOT - * ENOUGH to make SEH or exceptions work. - * - * Stack switching breaks SEH because the call stack no longer necessarily - * matches the SEH list. For example, given greenlet A that switches to - * greenlet B, at the moment of entering greenlet B, we will have any SEH - * handlers from greenlet A on the SEH list; greenlet B can then add its own - * handlers to the SEH list. When greenlet B switches back to greenlet A, - * greenlet B's handlers would still be on the SEH stack, but when switch() - * returns control to greenlet A, we have replaced the contents of the stack - * in memory, so all the address that greenlet B added to the SEH list are now - * invalid: part of the call stack has been unwound, but the SEH list was out - * of sync with the call stack. The net effect is that exception handling - * stops working. - * - * Thus, when switching greenlets, we need to be sure that the SEH list - * matches the effective call stack, "cutting out" any handlers that were - * pushed by the greenlet that switched out and which are no longer valid. - * - * The easiest way to do this is to capture the SEH list at the time the main - * greenlet for a thread is created, and, when initially starting a greenlet, - * start a new SEH list for it, which contains nothing but the handler - * established for the new greenlet itself, with the tail being the handlers - * for the main greenlet. If we then save and restore the SEH per-greenlet, - * they won't interfere with each others SEH lists. (No greenlet can unwind - * the call stack past the handlers established by the main greenlet). - * - * By observation, a new thread starts with three SEH handlers on the list. By - * the time we get around to creating the main greenlet, though, there can be - * many more, established by transient calls that lead to the creation of the - * main greenlet. Therefore, 3 is a magic constant telling us when to perform - * the initial slice. - * - * All of this can be debugged using a vectored exception handler, which - * operates independently of the SEH handler list, and is called first. - * Walking the SEH list at key points can also be helpful. - * - * References: - * https://en.wikipedia.org/wiki/Win32_Thread_Information_Block - * https://devblogs.microsoft.com/oldnewthing/20100730-00/?p=13273 - * https://docs.microsoft.com/en-us/cpp/cpp/try-except-statement?view=msvc-160 - * https://docs.microsoft.com/en-us/cpp/cpp/structured-exception-handling-c-cpp?view=msvc-160 - * https://docs.microsoft.com/en-us/windows/win32/debug/structured-exception-handling - * https://docs.microsoft.com/en-us/windows/win32/debug/using-a-vectored-exception-handler - * https://bytepointer.com/resources/pietrek_crash_course_depths_of_win32_seh.htm - */ -#define GREENLET_NEEDS_EXCEPTION_STATE_SAVED - - -typedef struct _GExceptionRegistration { - struct _GExceptionRegistration* prev; - void* handler_f; -} GExceptionRegistration; - -static void -slp_set_exception_state(const void *const seh_state) -{ - // Because the stack from from which we do this is ALSO a handler, and - // that one we want to keep, we need to relink the current SEH handler - // frame to point to this one, cutting out the middle men, as it were. - // - // Entering a try block doesn't change the SEH frame, but entering a - // function containing a try block does. - GExceptionRegistration* current_seh_state = (GExceptionRegistration*)__readfsdword(FIELD_OFFSET(NT_TIB, ExceptionList)); - current_seh_state->prev = (GExceptionRegistration*)seh_state; -} - - -static GExceptionRegistration* -x86_slp_get_third_oldest_handler() -{ - GExceptionRegistration* a = NULL; /* Closest to the top */ - GExceptionRegistration* b = NULL; /* second */ - GExceptionRegistration* c = NULL; - GExceptionRegistration* seh_state = (GExceptionRegistration*)__readfsdword(FIELD_OFFSET(NT_TIB, ExceptionList)); - a = b = c = seh_state; - - while (seh_state && seh_state != (GExceptionRegistration*)0xFFFFFFFF) { - if ((void*)seh_state->prev < (void*)100) { - fprintf(stderr, "\tERROR: Broken SEH chain.\n"); - return NULL; - } - a = b; - b = c; - c = seh_state; - - seh_state = seh_state->prev; - } - return a ? a : (b ? b : c); -} - - -static void* -slp_get_exception_state() -{ - // XXX: There appear to be three SEH handlers on the stack already at the - // start of the thread.
