The libc APIs always result in failure. The mcheck implementation has also been moved entirely into libc_malloc_debug.so and with it, all of the hook initialization code can now be moved into the debug library. Now the initialization can be done independently of libc internals. With this patch, libc_malloc_debug.so can no longer be used with older libcs, which is not its goal anyway. tst-vfork3 breaks due to this since it spawns shell scripts, which in turn execute using the system glibc. Move the test to tests-container so that only the built glibc is used. This move also fixes bugs in the mcheck version of memalign and realloc, thus allowing removal of the tests from tests-mcheck exclusion list. --- include/mcheck.h | 4 - malloc/Makefile | 3 - malloc/Versions | 9 + malloc/hooks.c | 61 +-- malloc/malloc-debug.c | 173 +++++++- malloc/mcheck-impl.c | 406 ++++++++++++++++++ malloc/mcheck.c | 397 +---------------- posix/Makefile | 8 +- .../mach/hurd/i386/libc_malloc_debug.abilist | 8 + .../linux/aarch64/libc_malloc_debug.abilist | 8 + .../linux/alpha/libc_malloc_debug.abilist | 8 + .../sysv/linux/arc/libc_malloc_debug.abilist | 8 + .../linux/arm/be/libc_malloc_debug.abilist | 8 + .../linux/arm/le/libc_malloc_debug.abilist | 8 + .../sysv/linux/csky/libc_malloc_debug.abilist | 8 + .../sysv/linux/hppa/libc_malloc_debug.abilist | 8 + .../sysv/linux/i386/libc_malloc_debug.abilist | 8 + .../sysv/linux/ia64/libc_malloc_debug.abilist | 8 + .../m68k/coldfire/libc_malloc_debug.abilist | 8 + .../m68k/m680x0/libc_malloc_debug.abilist | 8 + .../microblaze/be/libc_malloc_debug.abilist | 8 + .../microblaze/le/libc_malloc_debug.abilist | 8 + .../mips/mips32/fpu/libc_malloc_debug.abilist | 8 + .../mips32/nofpu/libc_malloc_debug.abilist | 8 + .../mips/mips64/n32/libc_malloc_debug.abilist | 8 + .../mips/mips64/n64/libc_malloc_debug.abilist | 8 + .../linux/nios2/libc_malloc_debug.abilist | 8 + .../powerpc32/fpu/libc_malloc_debug.abilist | 8 + .../powerpc32/nofpu/libc_malloc_debug.abilist | 8 + .../powerpc64/be/libc_malloc_debug.abilist | 8 + .../powerpc64/le/libc_malloc_debug.abilist | 8 + .../riscv/rv32/libc_malloc_debug.abilist | 8 + .../riscv/rv64/libc_malloc_debug.abilist | 8 + .../s390/s390-32/libc_malloc_debug.abilist | 8 + .../s390/s390-64/libc_malloc_debug.abilist | 8 + .../linux/sh/be/libc_malloc_debug.abilist | 8 + .../linux/sh/le/libc_malloc_debug.abilist | 8 + .../sparc/sparc32/libc_malloc_debug.abilist | 8 + .../sparc/sparc64/libc_malloc_debug.abilist | 8 + .../linux/x86_64/64/libc_malloc_debug.abilist | 8 + .../x86_64/x32/libc_malloc_debug.abilist | 8 + 41 files changed, 861 insertions(+), 464 deletions(-) create mode 100644 malloc/mcheck-impl.c diff --git a/include/mcheck.h b/include/mcheck.h index 8883c3d53e..5ad7cd1313 100644 --- a/include/mcheck.h +++ b/include/mcheck.h @@ -3,9 +3,5 @@ #include # ifndef _ISOMAC - -libc_hidden_proto (mcheck) -libc_hidden_proto (mcheck_check_all) - # endif /* !_ISOMAC */ #endif diff --git a/malloc/Makefile b/malloc/Makefile index feecd9464e..d2a44686a9 100644 --- a/malloc/Makefile +++ b/malloc/Makefile @@ -90,9 +90,6 @@ tests-exclude-mcheck = tst-mallocstate \ tst-malloc-thread-fail \ tst-malloc-usable-tunables \ tst-malloc_info \ - tst-memalign \ - tst-posix_memalign \ - tst-realloc \ tst-compathooks-off tst-compathooks-on tests-mcheck = $(filter-out $(tests-exclude-mcheck), $(tests)) diff --git a/malloc/Versions b/malloc/Versions index c87f6df8ca..6548970419 100644 --- a/malloc/Versions +++ b/malloc/Versions @@ -110,8 +110,17 @@ libc_malloc_debug { realloc; valloc; + __free_hook; + __malloc_hook; + __memalign_hook; + __realloc_hook; + + mcheck; + mprobe; } GLIBC_2.2 { + mcheck_check_all; + mcheck_pedantic; posix_memalign; } GLIBC_2.16 { diff --git a/malloc/hooks.c b/malloc/hooks.c index 0f7df88a28..208eb90edb 100644 --- a/malloc/hooks.c +++ b/malloc/hooks.c @@ -34,65 +34,10 @@ void *(*__morecore)(ptrdiff_t); compat_symbol (libc, __morecore, __morecore, GLIBC_2_0); #endif -static void *malloc_hook_ini (size_t, const void *) __THROW; -static void *realloc_hook_ini (void *, size_t, const void *) __THROW; -static void *memalign_hook_ini (size_t, size_t, const void *) __THROW; - void weak_variable (*__free_hook) (void *, const void *) = NULL; -void *weak_variable (*__malloc_hook) - (size_t, const void *) = malloc_hook_ini; -void *weak_variable (*__realloc_hook) - (void *, size_t, const void *) = realloc_hook_ini; -void *weak_variable (*__memalign_hook) - (size_t, size_t, const void *) = memalign_hook_ini; - -/* Hooks for debugging versions.
