Madhavan T. Venkataraman 9ba55921 2021-03-05T10:07:30 Static tramp v5 (#624) * Static Trampolines Closure Trampoline Security Issue ================================= Currently, the trampoline code used in libffi is not statically defined in a source file (except for MACH). 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. Support for other OSes can be added very easily.

Anthony Green 70c303cb 2014-05-11T09:56:40 Fix testsuite for GCC 4.9.0
Josh Triplett d3695227 2014-04-20T12:03:25 Support fastcall closures libffi on 32-bit x86 now supports closures for all supported ABIs. Thus, rewrite the last remaining duplicated-by-ABI test (closure_stdcall and closure_thiscall) to use the generic ABI_NUM/ABI_ATTR mechanism.
Josh Triplett 7d698125 2014-03-26T23:17:56 Use the proper C++ compiler to run C++ tests Running the C compiler with -shared-libgcc -lstdc++ does not work on non-GCC compilers.
Josh Triplett 9946a92a 2014-03-26T20:18:58 Stop looking for expect and runtest above top_builddir Users wishing to test hand-compiled versions of expect and runtest can easily enough put them in their path or set EXPECT and RUNTEST themselves.
Josh Triplett acb20232 2014-03-26T20:18:41 Stop setting an empty AM_RUNTESTFLAGS
Josh Triplett e48918ec 2014-03-16T20:29:27 testsuite: Add ABIs to the test matrix; unify tests across ABIs This eliminates all the *_win32.c tests in favor of the tests they were branched from, and expands test coverage to run many more tests on stdcall, thiscall, and fastcall. This same mechanism also supports testing any other target that has multiple ABIs.
Josh Triplett 4d4d368e 2014-03-16T17:02:05 testsuite: Replace ffitestcxx.h with ffitest.h ffitest.h contains a superset of the functionality of ffitestcxx.h; make the C++ tests include ffitest.h instead, and remove ffitestcxx.h.
Josh Triplett 0d9cce8e 2014-03-16T16:22:58 testsuite: ffitest.h: Parenthesize the CHECK macro
Josh Triplett 3f97cf34 2014-03-16T16:53:42 testsuite: Unify the C and C++ testsuites These two testsuites differ only in the source file glob and a couple of additional compiler options; unify the remaining bits.
Josh Triplett 5695ec14 2014-03-16T16:04:58 testsuite: Factor out a function to run a matrix of tests This commons up code from libffi.call/call.exp and libffi.special/special.exp, unifies the optimization option matrix between the two, and makes it easier to add more axes to the matrix in the future.
Josh Triplett dfdb02cc 2014-03-16T15:26:26 testsuite: Introduce a __THISCALL__ compiler-specific macro
Josh Triplett bad89483 2014-03-16T15:16:18 testsuite: Introduce a __STDCALL__ compiler-specific macro Several tests want to use stdcall, which differs in syntax by compiler, so introduce a macro for it in ffitest.h.
Josh Triplett 98a793fa 2014-03-16T15:20:36 testsuite: Common up the ifdef blocks for compiler-specific macros
Josh Triplett e1911f78 2014-03-16T03:25:53 Add support for stdcall, thiscall, and fastcall on non-Windows x86-32 Linux supports the stdcall calling convention, either via functions explicitly declared with the stdcall attribute, or via code compiled with -mrtd which effectively makes stdcall the default. This introduces FFI_STDCALL, FFI_THISCALL, and FFI_FASTCALL on non-Windows x86-32 platforms, as non-default calling conventions.
Josh Triplett 9c279328 2014-03-16T02:31:19 testsuite: Remove fragile stack pointer checks testsuite/libffi.call/closure_stdcall.c and testsuite/libffi.call/closure_thiscall.c include inline assembly to save the stack pointer before and after the call, and compare the values. However, compilers can and do leave the stack in different states for these two pieces of inline assembly, such as by saving a temporary value on the stack across the call; observed with gcc -Os, and verified as spurious through careful inspection of disassembly.
