So that we can always get the full stack trace regardless of gcc's handling
of the "noreturn" attribute associated with abort().
BUG:6455193
Change-Id: Id264a5167e7cabbf11515fbc48f5469c527e34d4
The allocation size in chk_malloc(), leak_malloc(), and leak_memalign()
functions may be rounded up to a small value, leading to buffer overflows.
The code only runs in debugging mode.
This patch complements commit 6f04a0f4 (CVE-2009-0607).

ARM Cortex A8 use 64 bytes and ARM Cortex A9 use 32 bytes cache line
size.
The following patch:
Adds code to adjust memcpy cache line size to match A9 cache line
size.
Adds a flag to select between 32 bytes and 64 bytes cache line
size.

The posix_memalign(3) function is very similar to the traditional
memalign(3) function, but with better error reporting and a guarantee
that the memory it allocates can be freed. In bionic, memalign(3)
allocated memory can be freed, so posix_memalign(3) is just a wrapper
around memalign(3).

By default, Android no longer compiles code using it's custom
linker script /build/core/armelf.xsc. However, this causes
problems for libc. Certain programs linked using older versions
of GOLD expect libc.so to export __exidx_start and __exidx_end.
Removing the custom linker script causes libc.so not to export
those symbols.
For now, continue using the old linker script, until we can
figure out a better solution.

The ARM static linker wasn't properly handling __exidx_start
and __exidx_end symbols. Now that the static linker has been fixed,
we don't need the dynamic linker to work around this problem.

In bionic/libc/SYSCALLS.TXT, the prototype of system call
clock_nanosleep is incorrect.
According to man page:
int clock_nanosleep(clockid_t clock_id, int flags,
const struct timespec *request,
struct timespec *remain);

In bionic/libc/SYSCALLS.TXT, the prototypes of system call
getresuid/getresgid are incorrect.
According to man page, they should be:
int getresuid(uid_t *ruid, uid_t *euid, uid_t *suid);
int getresgid(gid_t *rgid, gid_t *egid, gid_t *sgid);

The root of the problem is that the existing implementation is based on the
ARM C++ ABI, which mandates a different guard variable layout than the
Itanium/x86 C++ one.
This patch modifies the implementation in a way that satisfies both ABIs (and
doesn't require changing the toolchains).
