There were some terrible subtle bugs caused by not respecting this. stackAlloc knows that the stack should be 16 aligned, so we can use stackAlloc(0) to enforce this. This way if alignment requirements change, as long as Emscripten updates stackAlloc to continue to enforce them we should be okay. * Fix handling of systems with no Js bigint integration When we run the node tests we use node v14 tests (since node v14 is vendored with Emscripten). Node v14 has no Js bigint integration unless the --experimental-wasm-bigint flag is passed. So only the node tests really notice if we get this right. Turns out, it didn't work. We can't call a JavaScript function with 64 bit integer arguments without bigint integration. In ffi_call, we are trying to call a wasm function that takes 64 bit integer arguments. dynCall is designed to do this. We need to go back to tracking the signature when we don't have WASM_BIGINT, and then use dynCall. This works better now that emscripten can dynamically fill in extra dynCall wrappers: https://github.com/emscripten-core/emscripten/pull/17328 On the other hand, for the closures we are not getting a function pointer as a first argument. We need to make our own wasm legalizer adaptor that splits 64 bit integer arguments and then calls the JavaScript trampoline, then the JavaScript trampoline reassembles them, calls the closure, then splits the result (if it's a 64 bit integer) and the adaptor puts it back together. * Improvements to emscripten test shell scripts (#21) This fixes the C++ unwinding tests and makes other minor improvements to the Emscripten test shell scripts. * Rename the test folder and move test files into emscripten test folder * Use docker image that has autoconf-2.71 * Cleanup * Pin emscripten 3.1.30 * Fix build.sh path * Rearrange ci pipeline * Fix bpo_38748 test * Cleanup * Improvements to comments, add static asserts, and update copyright * Use `*_js` instead of `*_helper` for EM_JS functions (#22) * Minor code simplification * Xfail first dejagnu test to work around emscripten cache messages See https://github.com/emscripten-core/emscripten/issues/18607 * Remove unneeded xfails * Shorten conftest.py by using pytest-pyodide * Apply formatters and linters to emscripten directory * Fix Emscripten xfail hack * Fix build-tests script * Patch emscripten to quiet info messages * Clean up compiler flags in scripts and remove some settings from circleci config * Rename emscripten quiet script * Add missing export * Don't remove go.exp * Add reference to emscripten logging issue --------- Co-authored-by: Kleis Auke Wolthuizen <info@kleisauke.nl> Co-authored-by: Kleis Auke Wolthuizen <github@kleisauke.nl> Co-authored-by: Christian Heimes <christian@python.org>

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.

hjl-tools 78556561 2020-02-21T19:08:06 x86: Add indirect branch tracking support (#540) Intel Control-flow Enforcement Technology (CET): https://software.intel.com/en-us/articles/intel-sdm contains shadow stack (SHSTK) and indirect branch tracking (IBT). When CET is enabled, ELF object files must be marked with .note.gnu.property section. When Intel CET is enabled, include <cet.h> in assembly codes to mark Intel CET support. Also when IBT is enabled, all indirect branch targets must start with ENDBR instruction and notrack prefix can be used to disable IBT on indirect branch. <cet.h> defines _CET_ENDBR which can be used in assembly codes for ENDBR instruction. If <cet.h> isn't included, define _CET_ENDBR as empty so that _CET_ENDBR can be used in assembly codes. Trampoline must be enlarged to add ENDBR instruction unconditionally, which is NOP on non-CET processors. This is required regardless if libffi is enabled with CET since libffi.so will be marked in legacy bitmap, but trampoline won't. Update library version for larger FFI_TRAMPOLINE_SIZE. This fixed: https://github.com/libffi/libffi/issues/474 Tested with $ CC="gcc -Wl,-z,cet-report=error -fcf-protection" CXX="g++ -Wl,-z,cet-report=error -fcf-protection" .../configure on Linux CET machines in i686, x32 and x86-64 modes.

Tom Tromey 6dd5fd5a 2016-02-22T15:34:39 fix documentation building An earlier patch added --disable-docs, but went too far, making it impossible to build the docs. It turns out that Automake seemingly has a bug preventing the conditional build of an info file. So, this patch works around the bug by putting the info_TEXINFOS rule into a new doc/Makefile.am.

Richard Henderson 9f112619 2014-11-22T20:02:43 x86: Best guess at update for Darwin
Richard Henderson 5d69d57a 2014-11-13T13:50:39 configure: Move target source selection into configure.host This eliminates the AM_CONDITIONAL ugliness, which eliminates just a bit of extra boilerplate for a new target. At the same time, properly categorize the EXTRA_DIST files into SOURCES and HEADERS, for the generation of ctags.
Richard Henderson 2b27890b 2014-10-24T16:10:48 sparc: Rewrite everything It's impossible to call between v8 and v9 ABIs, because of the stack bias in the v9 ABI. So let's not pretend it's just not implemented yet. Split the v9 code out to a separate file. The register windows prevent ffi_call from setting up the entire stack frame the assembly, but we needn't make an indirect call back to prep_args.
Richard Henderson a4b785ea 2014-10-17T02:07:32 arm: Rewrite ffi_closure Move the push of the argument registers into ffi_closure_SYSV, reducing the size of the trampoline.
Richard Henderson b21ec1ce 2014-11-05T10:15:25 x86: Rewrite closures Move everything into sysv.S, removing win32.S and freebsd.S. Handle all abis with a single ffi_closure_inner function. Move complexity of the raw THISCALL trampoline into assembly instead of the trampoline itself. Only push the context for the REGISTER abi; let the rest receive it in a register.
Richard Henderson 99db4d42 2014-10-23T14:12:18 win64: Rewrite It's way too different from the 32-bit ABIs with which it is currently associated. As seen from all of the existing XFAILs.
Sebastian Macke 0f316ab7 2014-09-27T00:19:15 Add OpenRISC support This patch adds support for the OpenRISC architecture. (http://opencores.org/or1k/Main_Page) This patch has been tested under Linux with QEMU-user emulation support. - 32 Bit - big endian - delayed instructions This is the only available configuration under Linux. The description of the ABI can be found on the official website. Is passes the testsuite except of the unwindtest_ffi_call.cc testcase, which seems to be a problem of gcc and not libffi. Some testcases of the gcc testsuite still fail. Signed-off-by: Sebastian Macke <sebastian@macke.de>

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.

Alan Modra ab79d6e2 2013-11-21T06:12:35 This separates the 32-bit sysv/linux/bsd code from the 64-bit linux code, and makes it possible to link code compiled with different options to those used to compile libffi. For example, a -mlong-double-128 libffi can be used with -mlong-double-64 code. Using the return value area as a place to pass parameters wasn't such a good idea, causing a failure of cls_ulonglong.c. I didn't see this when running the mainline gcc libffi testsuite because that version of the test is inferior to the upstreamm libffi test. Using NUM_FPR_ARG_REGISTERS rather than NUM_FPR_ARG_REGISTERS64 meant that a parameter save area could be allocated before it was strictly necessary. Wrong but harmless. Found when splitting apart ffi.c into 32-bit and 64-bit support.
