* Fix x86_64 memchr for large input sizesAdhemerval Zanella2016-12-271-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Current optimized memchr for x86_64 does for input arguments pointers module 64 in range of [49,63] if there is no searchr char in the rest of 64-byte block a pointer addition which might overflow: * sysdeps/x86_64/memchr.S 77 .p2align 4 78 L(unaligned_no_match): 79 add %rcx, %rdx Add (uintptr_t)s % 16 to n in %rdx. 80 sub $16, %rdx 81 jbe L(return_null) This patch fixes by adding a saturated math that sets a maximum pointer value if it overflows (UINTPTR_MAX). Checked on x86_64-linux-gnu and powerpc64-linux-gnu. [BZ# 19387] * sysdeps/x86_64/memchr.S (memchr): Avoid overflow in pointer addition. * string/test-memchr.c (do_test): Remove alignment limitation. (test_main): Add test that trigger BZ# 19387.

* Fix powerpc64/power7 memchr for large input sizesAdhemerval Zanella2016-12-161-9/+29
| | | | | | | | | | | | | | | | | | | | | | | Current optimized powercp64/power7 memchr uses a strategy to check for p versus align(p+n) (where 'p' is the input char pointer and n the maximum size to check for the byte) without taking care for possible overflow on the pointer addition in case of large 'n'. It was triggered by 3038145ca23 where default rawmemchr (used to created ppc64 rawmemchr in ifunc selection) now uses memchr (p, c, (size_t)-1) on its implementation. This patch fixes it by implement a satured addition where overflows sets the maximum pointer size to UINTPTR_MAX. Checked on powerpc64le-linux-gnu. [BZ# 20971] * sysdeps/powerpc/powerpc64/power7/memchr.S (__memchr): Avoid overflow in pointer addition. * string/test-memchr.c (do_test): Add an argument to pass as the size on memchr. (test_main): Add check for SIZE_MAX.
