* x86-64 memcmp: Use unsigned Jcc instructions on size [BZ #24155]H.J. Lu2019-02-041-8/+12
| | | | | | | | | | | | | | | | Since the size argument is unsigned. we should use unsigned Jcc instructions, instead of signed, to check size. Tested on x86-64 and x32, with and without --disable-multi-arch. [BZ #24155] CVE-2019-7309 * NEWS: Updated for CVE-2019-7309. * sysdeps/x86_64/memcmp.S: Use RDX_LP for size. Clear the upper 32 bits of RDX register for x32. Use unsigned Jcc instructions, instead of signed. * sysdeps/x86_64/x32/Makefile (tests): Add tst-size_t-memcmp-2. * sysdeps/x86_64/x32/tst-size_t-memcmp-2.c: New test.
