to an exception vector. In vmx non-root, if an exception occurs, the processor checks the corresponding bit of prediction_bitmap, if this bit is 1, Vm-exit is generated. When it is 0, the exception handling routine is executed through guest-IDT. When triple-fault occurs, Vm-exit is directly generated./Prediction_bitmap = 0x00004004 ,/Exception bitmap, exception Control/Page_fault_error_code_mask = 0x00004006,Page_fault_error_code_match = 0x00004008,/The maximum value is 4./Cr3_target_count = 0x

deceives fixedbit for further optimization. Finally, let's take a look at sfixedbit. In fact, only one of its functions is to mark the main mainthread. That is, the starting point of the concept. We call the layout returned by lua_newstate. Why should we take this layout into special consideration? Because even when lua_close is reached, this structure cannot be cleared. Let's take a look at what the French performed at the end of the day? See the 105 rows of lstate. C. static void close_state

LUA Code Encryption Scheme

, which simulates the Searcher_lua function, searches the path, and then matches the file one by one, then reads the file contents, decrypts, Then call load to load and return (Lual_loadbufferx in C), where it is best to pass in the file name as the source parameter when loading, so that it is easy to locate in debug information. Encryption schemes can use a xxtea-like, lightweight encryption algorithm When you encrypt a LUA file, you can write the specified signature to the file header

LUA state loads some libraries

In Lua, we usually load all the Lub standard libraries with lual_openlibs (L), but sometimes we want to load only the parts, is there any good way? See the following methods in Luaproc:Static voidRegisterlib (Lua_state *l,Const Char*name, Lua_cfunction f) {Lua_getglobal (L," Package" ); Lua_getfield (L,-1,"preload" ); Lua_pushcfunction (L, F); Lua_setfield (L,-2, name); Lua_pop (L,2 );}Static voidOpenlibs (Lua_state *l) {lua_cpcall (L, Luaopen_base, NULL); Lua_cpcall (L, Luaopen_package, N

Linux inittab file details

understand the inittab file. The values in the inittab file are in the following format: Label is 1 ~ A four-character tag that identifies the input value. Some systems only support 2 Characters of tags. For this reason, most people limit the number of tag characters to less than 2. The tag can be a string composed of any characters, but in fact, some specific labels are commonly used. The labels used in Red Hat Linux are: Code: Id is used to define the default init running level Si is the pro
