* x86-64 memrchr: Properly handle the length parameter [BZ# 24097]H.J. Lu2019-01-211-2/+2
| | | | | | | | | | | | | | | | | | On x32, the size_t parameter may be passed in the lower 32 bits of a 64-bit register with the non-zero upper 32 bits. The string/memory functions written in assembly can only use the lower 32 bits of a 64-bit register as length or must clear the upper 32 bits before using the full 64-bit register for length. This pach fixes memrchr for x32. Tested on x86-64 and x32. On x86-64, libc.so is the same with and withou the fix. [BZ# 24097] CVE-2019-6488 * sysdeps/x86_64/memrchr.S: Use RDX_LP for length. * sysdeps/x86_64/multiarch/memrchr-avx2.S: Likewise. * sysdeps/x86_64/x32/Makefile (tests): Add tst-size_t-memrchr. * sysdeps/x86_64/x32/tst-size_t-memrchr.c: New file.

* x86_64: Remove redundant REX bytes from memrchr.SH.J. Lu2017-06-051-19/+17
| | | | | | | | | | | | | | | | | | By x86-64 specification, 32-bit destination registers are zero-extended to 64 bits. There is no need to use 64-bit registers when only the lower 32 bits are non-zero. Also 2 instructions in: mov %rdi, %rcx and $15, %rcx jz L(length_less16_offset0) mov %rdi, %rcx <<< redundant and $15, %rcx <<< redundant are redundant. * sysdeps/x86_64/memrchr.S (__memrchr): Use 32-bit registers for the lower 32 bits. Remove redundant instructions.

* Fix x86_64 memrchr namespace (bug 17719).Joseph Myers2014-12-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | On x86_64, memrchr (not a standard function) is defined as a strong symbol, instead of a weak alias of __memrchr as on other architectures. This results in linknamespace test failures from the use of __memrchr from dirname. (Not a conformance issue because of the mem* reservation, but contrary to glibc conventions.) This patch makes x86_64 follow other architectures by defining memrchr as a weak alias. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17719] * sysdeps/x86_64/memrchr.S (memrchr): Rename to __memrchr and define as weak alias of __memrchr. (__memrchr): Do not define as strong alias of memrchr. * conform/Makefile (test-xfail-XPG4/libgen.h/linknamespace): Remove variable. (test-xfail-UNIX98/libgen.h/linknamespace): Likewise. (test-xfail-XOPEN2K/libgen.h/linknamespace): Likewise. (test-xfail-XOPEN2K8/libgen.h/linknamespace): Likewise.
