Ryan C. Underwood d4640608 2018-03-18T07:00:42 Fully allocate file backing writable maps (#389) When ftruncate() is used on a filesystem supporting sparse files, space in the file is not actually allocated. Then, when the file is mmap'd and libffi writes to the mapping, SIGBUS is thrown to the calling application. Instead, always fully allocate the file that will back writable maps.

Andreas Schwab e66fd678 2018-02-20T10:47:09 Revert "Fix passing struct by value on aarch64" This reverts commit 482b37f00467325e3389bab322525099860dd9aa. That was actually a bug in python, see <https://bugs.python.org/issue30353>.
Sergei Trofimovich b58caef7 2018-02-17T19:00:40 ia64: fix small struct return This change fixes libffi.call/struct10.c failure on ia64: FAIL: libffi.call/struct10.c -W -Wall -Wno-psabi -O0 execution test .Lst_small_struct handles returns for structs less than 32 bytes (following ia64 return value ABI [1]). Subroutine does roughly the following: ``` mov [sp+0] = r8 mov [sp+8] = r9 mov [sp+16] = r10 mov [sp+24] = r11 memcpy(destination, source=sp, 12); ``` The problem: ia64 ABI guarantees that top 16 bytes of stack are scratch space for callee function. Thus it can clobber it. [1] says (7.1 Procedure Frames): """ * Scratch area. This 16-byte region is provided as scratch storage for procedures that are called by the current procedure. Leaf procedures do not need to allocate this region. A procedure may use the 16 bytes at the top of its own frame as scratch memory, but the contents of this area are not preserved by a procedure call. """ In our case 16 top bytes are clobbered by a PLT resolver when memcpy() is called for the first time. As a result memcpy implementation reads already clobbered data frop top of stack. The fix is simple: allocate 16 bytes of scrats space prior to memcpy() call.

Sergei Trofimovich 45da2fcb 2018-02-17T18:53:02 new test: return small struct The bug originally was discovered in https://bugs.gentoo.org/634190 where complicated callback was returning invalid data on ia64. This change adds minimal reproducer that fails only on ia64 as: FAIL: libffi.call/struct10.c -W -Wall -Wno-psabi -O0 execution test FAIL: libffi.call/struct10.c -W -Wall -Wno-psabi -O2 execution test FAIL: libffi.call/struct10.c -W -Wall -Wno-psabi -O3 execution test FAIL: libffi.call/struct10.c -W -Wall -Wno-psabi -Os execution test Test passes on amd64. The fix is in the following commit. Bug: https://bugs.gentoo.org/634190 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
Sergei Trofimovich 11de69dd 2018-02-11T11:29:39 ia64: fix variadic function closures with FP arguments libffi test framework already flagged failures as: ``` FAIL: libffi.call/cls_double_va.c -W -Wall -Wno-psabi -O0 output pattern test, is 7.0 res: 4 0.0 res: 4 ? should match 7.0 ?es: 4 ?.0 res: 4 ``` Failure happens here at ```c // testsuite/libffi.call/cls_double_va.c ... char* format = "%.1f\n"; double doubleArg = 7; ... CHECK(ffi_prep_closure_loc(pcl, &cif, cls_double_va_fn, NULL, code) == FFI_OK); res = ((int(*)(char*, ...))(code))(format, doubleArg); ``` libffi expects 'doubleArg' to be located in 'f9' (second FP argument) but gcc placed it to 'r33' (second GR). ia64 software [1] manual described argument passing ABI in "8.5.2 Register Parameters" as: """ If an actual parameter is known to correspond to a floating-point formal parameter, the following rules apply: a) The actual parameter is passed in the next available floating-point parameter register, if one is available. Floating-point parameter registers are allocated as needed from the range f8-f15, starting with f8. b) If all available floating-point parameter registers have been used, the actual parameter is passed in the appropriate general register(s). (This case can occur only as a result of homogeneous floating-point aggregates, described below.) If a floating-point actual parameter is known to correspond to a variable-argument specification in the formal parameter list, the following rule applies: c) The actual parameter is passed in the appropriate general register(s). If the compiler cannot determine, at the point of call, whether the corresponding formal parameter is a varargs parameter, it must generate code that satisfies both of the above conditions. (The compiler’s determination may be based on prototype declarations, language standard assumptions, analysis, or other user options or information.) """ We have [c] case here and gcc uses only GR for parameter passing. The change binds known variadic arguments ro GRs instead of FPs as those are always expected to be initialized for all variadic call types. This fixes all 10 failures on ia64-unknown-linux-gnu: ``` === libffi Summary === -# of expected passes 1945 -# of unexpected failures 10 + +# of expected passes 1955 ``` [1]: https://www.intel.com/content/dam/www/public/us/en/documents/guides/itanium-software-runtime-architecture-guide.pdf Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

Saleem Abdulrasool 3c372c38 2017-10-24T13:53:56 arm: fix a level of indirection issue Rather than relying on the stack being 0'ed out always, do it manually. The stack generally happened to be zero, and because the compiler realizes that the tests are dealing with chars truncates the read value. However, the top 3 nibbles of the value are undefined and may be non-zero. The indirection level caused a null-pointer dereference. Explicitly scribbling on the stack during the allocation causes test failures without the original zexting behaviour.
