* lseek: avoid SEEK_HOLE bugs in FreeBSD, macOSPaul Eggert2023-02-231-0/+5
| | | | | | | | | | | | | This attempts to fix <https://bugs.gnu.org/61386>, a bug in GNU cp caused by a serious data corruption bug in FreeBSD and macOS. * doc/posix-functions/lseek.texi: Mention the bug. * lib/unistd.in.h (SEEK_DATA, SEEK_HOLE): Undef in macOS < 13 and FreeBSD < 14. FreeBSD fixed the bug sometime during FreeBSD 13 <https://bugs.freebsd.org/256205>, so the "FreeBSD < 14" is conservative. It’s unknown when Apple will fix macOS so use macOS "9999" as a placeholder. * m4/lseek.m4 (gl_FUNC_LSEEK): Replace lseek if on one of the above platforms.

* malloc, etc.: check for ptrdiff_t overflowPaul Eggert2021-04-173-21/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In glibc 2.30 and later, malloc, realloc and calloc reject attempts to create objects larger than PTRDIFF_MAX bytes. This patch changes malloc-gnu etc. to support this behavior on non-GNU hosts. It also makes this change for malloc-posix etc. since it’s a safety measure that ought to be in POSIX (perhaps we can talk them into that...). In writing this patch I found a complicated set of code that had accumulated over the years, some written by yours truly. I got rid of the code I couldn’t see the need for nowadays. Among other things, the GNU realloc behavior is no longer incompatible with the C standard, because in C17 the latter was relaxed to allow the former. If I went too far in cleaning up, the old stuff can be resurrected. This change is mostly for 32-bit platforms, since practical 64-bit platforms cannot create objects larger than PTRDIFF_MAX bytes anyway. * doc/posix-functions/calloc.texi: * doc/posix-functions/malloc.texi: * doc/posix-functions/realloc.texi: Mention ptrdiff_t issues, and go into more detail about what the gnu extension module does. * doc/posix-functions/realloc.texi: Fix now-obsolete commentary about C99 vs glibc, as C17 allows the glibc behavior and POSIX will follow suit when it gets around to it. * lib/calloc.c, lib/malloc.c, lib/realloc.c: Simplify by always supplying a GNU-compatible version, as that suffices for correctness and is good enough for performance. Include xalloc-oversized.h, and use xalloc_oversized to check for ptrdiff_t overflow. (NEED_CALLOC_GNU, NEED_MALLOC_GNU, NEED_REALLOC_GNU): Remove. * m4/calloc.m4 (_AC_FUNC_CALLOC_IF): * m4/malloc.m4 (_AC_FUNC_MALLOC_IF): * m4/realloc.m4 (_AC_FUNC_REALLOC_IF): Don’t start with a newline. Fix message to match behavior. * m4/calloc.m4 (_AC_FUNC_CALLOC_IF): Don’t test for size_t overflow, as the ptrdiff_t test is good enough. * m4/calloc.m4 (gl_FUNC_CALLOC_GNU): * m4/malloc.m4 (gl_FUNC_MALLOC_GNU): * m4/realloc.m4 (gl_FUNC_REALLOC_GNU): Do not define HAVE_CALLOC_GNU, HAVE_MALLOC_GNU, HAVE_REALLOC_GNU. It’s not worth the aggravation of maintaining these, as they are confusing (they don’t really mean GNU-compatible anyway). Don’t bother testing for GNU behavior if we have already decided to replace the function, since the replacement is always GNUish. * m4/calloc.m4 (gl_FUNC_CALLOC_POSIX): * m4/realloc.m4 (gl_FUNC_REALLOC_POSIX): Defer to gl_FUNC_MALLOC_POSIX. * m4/malloc.m4 (gl_FUNC_MALLOC_PTRDIFF, gl_CHECK_MALLOC_PTRDIFF): New macros. (gl_FUNC_MALLOC_POSIX): Use them to check for ptrdiff_t overflow. * modules/calloc-gnu, modules/malloc-gnu, modules/realloc-gnu: Remove no-longer-needed module indicators. * modules/calloc-posix, modules/malloc-posix, modules/realloc-posix: Depend on xalloc-oversized. * modules/malloc-posix: Require gl_FUNC_MALLOC_POSIX instead of calling it directly, so that other code can require it. * modules/realloc-posix: Depend on free-posix and malloc-posix.
