* Improve read-write .eh_frame check (#546)Fangrui Song2020-03-101-9/+3
| | | | | | | llvm-objdump -h does not print BFD SEC_* constants like "READONLY", so the check will consider .eh_frame writable. clang 11 (since https://reviews.llvm.org/D73999) will error for mismatching section flags. Use readelf -S and check "WA" instead.

* Revamp PA_LINUX and PA_HPUX target closures to use function descriptors.Moxie Bot2020-02-246-105/+67
| | | | | | | | | | | | | | | | | | | | 2020-02-23 John David Anglin <danglin@gcc.gnu.org> * include/ffi.h.in (FFI_CLOSURE_PTR, FFI_RESTORE_PTR): Define. * src/closures.c (ffi_closure_alloc): Convert closure pointer return by malloc to function pointer. (ffi_closure_free): Convert function pointer back to malloc pointer. * src/pa/ffi.c (ffi_closure_inner_pa32): Use union to double word align return address on stack. Adjust statements referencing return address. Convert closure argument from function pointer to standard closure pointer. (ffi_prep_closure_loc): Likewise convert closure argument back to closure pointer. Remove assembler trampolines. Setup simulated function descriptor as on ia64. src/pa/ffitarget.h (FFI_TRAMPOLINE_SIZE): Reduce to 12. src/pa/hpux32.S (ffi_closure_pa32): Retrieve closure pointer and real gp from fake gp value in register %r19. src/pa/linux.S (ffi_closure_pa32): Likewise.
* Update the ABI version to LIBFFI_BASE_8.0 (#544)hjl-tools2020-02-231-12/+8
| | | | | | Since x86 and x86-64 FFI_TRAMPOLINE_SIZE have been increased, we must bump the ABI version. This fixes: https://github.com/libffi/libffi/issues/543
* x86: Fix ffi_prep_closure_loc (#542)hjl-tools2020-02-221-1/+1
| | | | Since FFI_TRAMPOLINE_SIZE is increased by 4 bytes to add ENDBR32, adjust jump displacement by 4 bytes.

| * x86: Add indirect branch tracking support (#540)hjl-tools2020-02-219-31/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | Build failure looks as: ``` libtool: compile: powerpc-unknown-linux-gnu-gcc \ -O2 -mcpu=powerpc -mtune=powerpc -pipe ... -c src/powerpc/ffi.c ... In file included from src/powerpc/ffi.c:33: src/powerpc/ffi_powerpc.h:65:9: error: '__int128' is not supported on this target 65 | typedef __int128 float128; | ^~~~~~~~ ``` The fix avoids using __int128 in favour of aligned char[16].
