The trampoline is either pre-defined + machine code in a data buffer. Or, it is generated at runtime. In order to + execute a trampoline, it needs to be placed in a page with executable + permissions. + + Executable data pages are attack surfaces for attackers who may try to + inject their own code into the page and contrive to have it executed. The + security settings in a system may prevent various tricks used in user land + to write code into a page and to have it executed somehow. On such systems, + libffi trampolines would not be able to run. + + Static Trampoline + ================= + + To solve this problem, the trampoline code needs to be defined statically + in a source file, compiled and placed in the text segment so it can be + mapped and executed naturally without any tricks. However, the trampoline + needs to be able to access the closure pointer at runtime. + + PC-relative data referencing + ============================ + + The solution implemented in this patch set uses PC-relative data references. + The trampoline is mapped in a code page. Adjacent to the code page, a data + page is mapped that contains the parameters of the trampoline: + + - the closure pointer + - pointer to the ABI handler to jump to + + The trampoline code uses an offset relative to its current PC to access its + data. + + Some architectures support PC-relative data references in the ISA itself. + E.g., X64 supports RIP-relative references. For others, the PC has to + somehow be loaded into a general purpose register to do PC-relative data + referencing. To do this, we need to define a get_pc() kind of function and + call it to load the PC in a desired register. + + There are two cases: + + 1. The call instruction pushes the return address on the stack. + + In this case, get_pc() will extract the return address from the stack + and load it in the desired register and return. + + 2. The call instruction stores the return address in a designated register. + + In this case, get_pc() will copy the return address to the desired + register and return. + + Either way, the PC next to the call instruction is obtained. + + Scratch register + ================ + + In order to do its job, the trampoline code would need to use a scratch + register. Depending on the ABI, there may not be a register available for + scratch. This problem needs to be solved so that all ABIs will work. + + The trampoline will save two values on the stack: + + - the closure pointer + - the original value of the scratch register + + This is what the stack will look like: + + sp before trampoline ------> -------------------- + | closure pointer | + -------------------- + | scratch register | + sp after trampoline -------> -------------------- + + The ABI handler can do the following as needed by the ABI: + + - the closure pointer can be loaded in a desired register + + - the scratch register can be restored to its original value + + - the stack pointer can be restored to its original value + (the value when the trampoline was invoked) + + To do this, I have defined prolog code for each ABI handler. The legacy + trampoline jumps to the ABI handler directly. But the static trampoline + defined in this patch jumps tp the prolog code which performs the above + actions before jumping to the ABI handler. + + Trampoline Table + ================ + + In order to reduce the trampoline memory footprint, the trampoline code + would be defined as a code array in the text segment. This array would be + mapped into the address space of the caller. The mapping would, therefore, + contain a trampoline table. + + Adjacent to the trampoline table mapping, there will be a data mapping that + contains a parameter table, one parameter block for each trampoline. The + parameter block will contain: + + - a pointer to the closure + - a pointer to the ABI handler + + The static trampoline code would finally look like this: + + - Make space on the stack for the closure and the scratch register + by moving the stack pointer down + - Store the original value of the scratch register on the stack + - Using PC-relative reference, get the closure pointer + - Store the closure pointer on the stack + - Using PC-relative reference, get the ABI handler pointer + - Jump to the ABI handler + + Mapping size + ============ + + The size of the code mapping that contains the trampoline table needs to be + determined on a per architecture basis. If a particular architecture + supports multiple base page sizes, then the largest supported base page size + needs to be chosen. E.g., we choose 16K for ARM64. + + Trampoline allocation and free + ============================== + + Static trampolines are allocated in ffi_closure_alloc() and freed in + ffi_closure_free(). + + Normally, applications use these functions. But there are some cases out + there where the user of libffi allocates and manages its own closure + memory. In such cases, static trampolines cannot be used. These will + fall back to using legacy trampolines. The user has to make sure that + the memory is executable. + + ffi_closure structure + ===================== + + I did not want to make any changes to the size of the closure structure for + this feature to guarantee compatibility. But the opaque static trampoline + handle needs to be stored in the closure. I have defined it as follows: + + - char tramp[FFI_TRAMPOLINE_SIZE]; + + union { + + char tramp[FFI_TRAMPOLINE_SIZE]; + + void *ftramp; + + }; + + If static trampolines are used, then tramp[] is not needed to store a + dynamic trampoline. That space can be reused to store the handle. Hence, + the union. + + Architecture Support + ==================== + + Support has been added for x64, i386, aarch64 and arm. Support for other + architectures can be added very easily in the future. + + OS Support + ========== + + Support has been added for Linux.

These conventions are necessary, in part, for separate +compilation to work. One such convention is the "calling convention". +The calling convention is a set of assumptions made by the compiler +about where function arguments will be found on entry to a function. A +calling convention also specifies where the return value for a function +is found. The calling convention is also sometimes called the "ABI" or +"Application Binary Interface". + + Some programs may not know at the time of compilation what arguments +are to be passed to a function. For instance, an interpreter may be +told at run-time about the number and types of arguments used to call a +given function. 'Libffi' can be used in such programs to provide a +bridge from the interpreter program to compiled code. + + The 'libffi' library provides a portable, high level programming +interface to various calling conventions. This allows a programmer to +call any function specified by a call interface description at run time. + + FFI stands for Foreign Function Interface. A foreign function +interface is the popular name for the interface that allows code written +in one language to call code written in another language. The 'libffi' +library really only provides the lowest, machine dependent layer of a +fully featured foreign function interface. A layer must exist above +'libffi' that handles type conversions for values passed between the two +languages. + + +File: libffi.info, Node: Using libffi, Next: Memory Usage, Prev: Introduction, Up: Top + +2 Using libffi +************** + +* Menu: + +* The Basics:: The basic libffi API. +* Simple Example:: A simple example. +* Types:: libffi type descriptions. +* Multiple ABIs:: Different passing styles on one platform. +* The Closure API:: Writing a generic function. +* Closure Example:: A closure example. +* Thread Safety:: Thread safety. + + +File: libffi.info, Node: The Basics, Next: Simple Example, Up: Using libffi + +2.1 The Basics +============== + +'Libffi' assumes that you have a pointer to the function you wish to +call and that you know the number and types of arguments to pass it, as +well as the return type of the function. + + The first thing you must do is create an 'ffi_cif' object that +matches the signature of the function you wish to call. This is a +separate step because it is common to make multiple calls using a single +'ffi_cif'. The "cif" in 'ffi_cif' stands for Call InterFace. To +prepare a call interface object, use the function 'ffi_prep_cif'. + + -- Function: ffi_status ffi_prep_cif (ffi_cif *CIF, ffi_abi ABI, + unsigned int NARGS, ffi_type *RTYPE, ffi_type **ARGTYPES) + This initializes CIF according to the given parameters. + + ABI is the ABI to use; normally 'FFI_DEFAULT_ABI' is what you want. + *note Multiple ABIs:: for more information. + + NARGS is the number of arguments that this function accepts. + + RTYPE is a pointer to an 'ffi_type' structure that describes the + return type of the function. *Note Types::. + + ARGTYPES is a vector of 'ffi_type' pointers. ARGTYPES must have + NARGS elements. If NARGS is 0, this argument is ignored. + + 'ffi_prep_cif' returns a 'libffi' status code, of type + 'ffi_status'. This will be either 'FFI_OK' if everything worked + properly; 'FFI_BAD_TYPEDEF' if one of the 'ffi_type' objects is + incorrect; or 'FFI_BAD_ABI' if the ABI parameter is invalid. + + If the function being called is variadic (varargs) then +'ffi_prep_cif_var' must be used instead of 'ffi_prep_cif'. + + -- Function: ffi_status ffi_prep_cif_var (ffi_cif *CIF, ffi_abi ABI, + unsigned int NFIXEDARGS, unsigned int NTOTALARGS, ffi_type + *RTYPE, ffi_type **ARGTYPES) + This initializes CIF according to the given parameters for a call + to a variadic function. In general its operation is the same as + for 'ffi_prep_cif' except that: + + NFIXEDARGS is the number of fixed arguments, prior to any variadic + arguments. It must be greater than zero. + + NTOTALARGS the total number of arguments, including variadic and + fixed arguments. ARGTYPES must have this many elements. + + 'ffi_prep_cif_var' will return 'FFI_BAD_ARGTYPE' if any of the + variable argument types are 'ffi_type_float' (promote to + 'ffi_type_double' first), or any integer type small than an int + (promote to an int-sized type first). + + Note that, different cif's must be prepped for calls to the same + function when different numbers of arguments are passed. + + Also note that a call to 'ffi_prep_cif_var' with + NFIXEDARGS=NOTOTALARGS is NOT equivalent to a call to + 'ffi_prep_cif'. + + Note that the resulting 'ffi_cif' holds pointers to all the +'ffi_type' objects that were used during initialization. You must +ensure that these type objects have a lifetime at least as long as that +of the 'ffi_cif'. + + To call a function using an initialized 'ffi_cif', use the 'ffi_call' +function: + + -- Function: void ffi_call (ffi_cif *CIF, void *FN, void *RVALUE, void + **AVALUES) + This calls the function FN according to the description given in + CIF. CIF must have already been prepared using 'ffi_prep_cif'. + + RVALUE is a pointer to a chunk of memory that will hold the result + of the function call. This must be large enough to hold the + result, no smaller than the system register size (generally 32 or + 64 bits), and must be suitably aligned; it is the caller's + responsibility to ensure this. If CIF declares that the function + returns 'void' (using 'ffi_type_void'), then RVALUE is ignored. + + In most situations, 'libffi' will handle promotion according to the + ABI. However, for historical reasons, there is a special case with + return values that must be handled by your code. In particular, + for integral (not 'struct') types that are narrower than the system + register size, the return value will be widened by 'libffi'. + 'libffi' provides a type, 'ffi_arg', that can be used as the return + type. For example, if the CIF was defined with a return type of + 'char', 'libffi' will try to store a full 'ffi_arg' into the return + value. + + AVALUES is a vector of 'void *' pointers that point to the memory + locations holding the argument values for a call. If CIF declares + that the function has no arguments (i.e., NARGS was 0), then + AVALUES is ignored. Note that argument values may be modified by + the callee (for instance, structs passed by value); the burden of + copying pass-by-value arguments is placed on the caller. + + Note that while the return value must be register-sized, arguments + should exactly match their declared type. For example, if an + argument is a 'short', then the entry in AVALUES should point to an + object declared as 'short'; but if the return type is 'short', then + RVALUE should point to an object declared as a larger type - + usually 'ffi_arg'. + + +File: libffi.info, Node: Simple Example, Next: Types, Prev: The Basics, Up: Using libffi + +2.2 Simple Example +================== + +Here is a trivial example that calls 'puts' a few times. + + #include + #include + + int main() + { + ffi_cif cif; + ffi_type *args[1]; + void *values[1]; + char *s; + ffi_arg rc; + + /* Initialize the argument info vectors */ + args[0] = &ffi_type_pointer; + values[0] = &s; + + /* Initialize the cif */ + if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, + &ffi_type_sint, args) == FFI_OK) + { + s = "Hello World!"; + ffi_call(&cif, puts, &rc, values); + /* rc now holds the result of the call to puts */ + + /* values holds a pointer to the function's arg, so to + call puts() again all we need to do is change the + value of s */ + s = "This is cool!"; + ffi_call(&cif, puts, &rc, values); + } + + return 0; + } + + +File: libffi.info, Node: Types, Next: Multiple ABIs, Prev: Simple Example, Up: Using libffi + +2.3 Types +========= + +* Menu: + +* Primitive Types:: Built-in types. +* Structures:: Structure types. +* Size and Alignment:: Size and alignment of types. +* Arrays Unions Enums:: Arrays, unions, and enumerations. +* Type Example:: Structure type example. +* Complex:: Complex types. +* Complex Type Example:: Complex type example. + + +File: libffi.info, Node: Primitive Types, Next: Structures, Up: Types + +2.3.1 Primitive Types +--------------------- + +'Libffi' provides a number of built-in type descriptors that can be used +to describe argument and return types: + +'ffi_type_void' + The type 'void'.

It does so using its knowledge of the ABI. + + You might expect that you can simply read these fields for a type +that has been laid out by 'libffi'. However, there are some caveats. + + * The size or alignment of some of the built-in types may vary + depending on the chosen ABI. + + * The size and alignment of a new structure type will not be set by + 'libffi' until it has been passed to 'ffi_prep_cif' or + 'ffi_get_struct_offsets'. + + * A structure type cannot be shared across ABIs. Instead each ABI + needs its own copy of the structure type. + + So, before examining these fields, it is safest to pass the +'ffi_type' object to 'ffi_prep_cif' or 'ffi_get_struct_offsets' first. +This function will do all the needed setup. + + ffi_type *desired_type; + ffi_abi desired_abi; + ... + ffi_cif cif; + if (ffi_prep_cif (&cif, desired_abi, 0, desired_type, NULL) == FFI_OK) + { + size_t size = desired_type->size; + unsigned short alignment = desired_type->alignment; + } + + 'libffi' also provides a way to get the offsets of the members of a +structure. + + -- Function: ffi_status ffi_get_struct_offsets (ffi_abi abi, ffi_type + *struct_type, size_t *offsets) + Compute the offset of each element of the given structure type. + ABI is the ABI to use; this is needed because in some cases the + layout depends on the ABI. + + OFFSETS is an out parameter.

If OFFSETS is 'NULL', + then the type will be laid out but not otherwise modified. This + can be useful for accessing the type's size or layout, as mentioned + above. + + This function returns 'FFI_OK' on success; 'FFI_BAD_ABI' if ABI is + invalid; or 'FFI_BAD_TYPEDEF' if STRUCT_TYPE is invalid in some + way. Note that only 'FFI_STRUCT' types are valid here. + + +File: libffi.info, Node: Arrays Unions Enums, Next: Type Example, Prev: Size and Alignment, Up: Types + +2.3.4 Arrays, Unions, and Enumerations +-------------------------------------- + +2.3.4.1 Arrays +.............. + +'libffi' does not have direct support for arrays or unions. However, +they can be emulated using structures. + + To emulate an array, simply create an 'ffi_type' using +'FFI_TYPE_STRUCT' with as many members as there are elements in the +array. + + ffi_type array_type; + ffi_type **elements + int i; + + elements = malloc ((n + 1) * sizeof (ffi_type *)); + for (i = 0; i < n; ++i) + elements[i] = array_element_type; + elements[n] = NULL; + + array_type.size = array_type.alignment = 0; + array_type.type = FFI_TYPE_STRUCT; + array_type.elements = elements; + + Note that arrays cannot be passed or returned by value in C - +structure types created like this should only be used to refer to +members of real 'FFI_TYPE_STRUCT' objects. + + However, a phony array type like this will not cause any errors from +'libffi' if you use it as an argument or return type. This may be +confusing. + +2.3.4.2 Unions +.............. + +A union can also be emulated using 'FFI_TYPE_STRUCT'. In this case, +however, you must make sure that the size and alignment match the real +requirements of the union. + + One simple way to do this is to ensue that each element type is laid +out. Then, give the new structure type a single element; the size of +the largest element; and the largest alignment seen as well. + + This example uses the 'ffi_prep_cif' trick to ensure that each +element type is laid out. + + ffi_abi desired_abi; + ffi_type union_type; + ffi_type **union_elements; + + int i; + ffi_type element_types[2]; + + element_types[1] = NULL; + + union_type.size = union_type.alignment = 0; + union_type.type = FFI_TYPE_STRUCT; + union_type.elements = element_types; + + for (i = 0; union_elements[i]; ++i) + { + ffi_cif cif; + if (ffi_prep_cif (&cif, desired_abi, 0, union_elements[i], NULL) == FFI_OK) + { + if (union_elements[i]->size > union_type.size) + { + union_type.size = union_elements[i]; + size = union_elements[i]->size; + } + if (union_elements[i]->alignment > union_type.alignment) + union_type.alignment = union_elements[i]->alignment; + } + } + +2.3.4.3 Enumerations +.................... + +'libffi' does not have any special support for C 'enum's.

Note that + this object, and the types to which it refers, must be kept + alive until the closure itself is freed. + + USER_DATA + An arbitrary datum that is passed, uninterpreted, to your + closure function. + + CODELOC + The executable address returned by 'ffi_closure_alloc'. + + FUN + The function which will be called when the closure is invoked. + It is called with the arguments: + + CIF + The 'ffi_cif' passed to 'ffi_prep_closure_loc'. + + RET + A pointer to the memory used for the function's return + value. + + If the function is declared as returning 'void', then + this value is garbage and should not be used. + + Otherwise, FUN must fill the object to which this points, + following the same special promotion behavior as + 'ffi_call'. That is, in most cases, RET points to an + object of exactly the size of the type specified when CIF + was constructed. However, integral types narrower than + the system register size are widened. In these cases + your program may assume that RET points to an 'ffi_arg' + object. + + ARGS + A vector of pointers to memory holding the arguments to + the function. + + USER_DATA + The same USER_DATA that was passed to + 'ffi_prep_closure_loc'. + + 'ffi_prep_closure_loc' will return 'FFI_OK' if everything went ok, + and one of the other 'ffi_status' values on error. + + After calling 'ffi_prep_closure_loc', you can cast CODELOC to the + appropriate pointer-to-function type. + + You may see old code referring to 'ffi_prep_closure'. This function +is deprecated, as it cannot handle the need for separate writable and +executable addresses. + + +File: libffi.info, Node: Closure Example, Next: Thread Safety, Prev: The Closure API, Up: Using libffi + +2.6 Closure Example +=================== + +A trivial example that creates a new 'puts' by binding 'fputs' with +'stdout'. + + #include + #include + + /* Acts like puts with the file given at time of enclosure. */ + void puts_binding(ffi_cif *cif, void *ret, void* args[], + void *stream) + { + *(ffi_arg *)ret = fputs(*(char **)args[0], (FILE *)stream); + } + + typedef int (*puts_t)(char *); + + int main() + { + ffi_cif cif; + ffi_type *args[1]; + ffi_closure *closure; + + void *bound_puts; + int rc; + + /* Allocate closure and bound_puts */ + closure = ffi_closure_alloc(sizeof(ffi_closure), &bound_puts); + + if (closure) + { + /* Initialize the argument info vectors */ + args[0] = &ffi_type_pointer; + + /* Initialize the cif */ + if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, + &ffi_type_sint, args) == FFI_OK) + { + /* Initialize the closure, setting stream to stdout */ + if (ffi_prep_closure_loc(closure, &cif, puts_binding, + stdout, bound_puts) == FFI_OK) + { + rc = ((puts_t)bound_puts)("Hello World!"); + /* rc now holds the result of the call to fputs */ + } + } + } + + /* Deallocate both closure, and bound_puts */ + ffi_closure_free(closure); + + return 0; + } + + + +File: libffi.info, Node: Thread Safety, Prev: Closure Example, Up: Using libffi + +2.7 Thread Safety +================= + +'libffi' is not completely thread-safe. However, many parts are, and if +you follow some simple rules, you can use it safely in a multi-threaded +program. + + * 'ffi_prep_cif' may modify the 'ffi_type' objects passed to it. It + is best to ensure that only a single thread prepares a given + 'ffi_cif' at a time. + + * On some platforms, 'ffi_prep_cif' may modify the size and alignment + of some types, depending on the chosen ABI. On these platforms, if + you switch between ABIs, you must ensure that there is only one + call to 'ffi_prep_cif' at a time. + + Currently the only affected platform is PowerPC and the only + affected type is 'long double'. + + +File: libffi.info, Node: Memory Usage, Next: Missing Features, Prev: Using libffi, Up: Top + +3 Memory Usage +************** + +Note that memory allocated by 'ffi_closure_alloc' and freed by +'ffi_closure_free' does not come from the same general pool of memory +that 'malloc' and 'free' use. To accomodate security settings, 'libffi' +may aquire memory, for example, by mapping temporary files into multiple +places in the address space (once to write out the closure, a second to +execute it). The search follows this list, using the first that works: + + * A anonymous mapping (i.e. not file-backed) + + * 'memfd_create()', if the kernel supports it. + + * A file created in the directory referenced by the environment + variable 'LIBFFI_TMPDIR'. + + * Likewise for the environment variable 'TMPDIR'. + + * A file created in '/tmp'. + + * A file created in '/var/tmp'. + + * A file created in '/dev/shm'. + + * A file created in the user's home directory ('$HOME'). + + * A file created in any directory listed in '/etc/mtab'. + + * A file created in any directory listed in '/proc/mounts'. + + If security settings prohibit using any of these for closures, +'ffi_closure_alloc' will fail. + + +File: libffi.info, Node: Missing Features, Next: Index, Prev: Memory Usage, Up: Top + +4 Missing Features +****************** + +'libffi' is missing a few features.
