commit 89423f5d8ba05a099c2c62227a00a4f4eec59eb3
Author: Mark Wielaard <mark@klomp.org>
Date: Tue May 7 21:20:04 2019 +0200
Intercept stpcpy also in ld.so for arm64
On other arches stpcpy () is intercepted for both libc.so and ld.so.
But not on arm64, where it is only intercepted for libc.so.
This can cause memcheck warnings about the use of stpcpy () in ld.so
when called through dlopen () because ld.so contains its own copy of
that functions.
Fix by introducing VG_Z_LD_LINUX_AARCH64_SO_1 (the encoded name of
ld.so on arm64) and using that in vg_replace_strmem.c to intercept
stpcpy.

commit 791fe5ecf909d573bcbf353b677b9404f9da0ed4
Author: Mark Wielaard <mark@klomp.org>
Date: Mon May 27 22:19:27 2019 +0200
Expose rdrand and f16c through cpuid also if the host only has avx.
The amd64 CPUID dirtyhelpers are mostly static since they emulate some
existing CPU "family". The avx2 ("i7-4910MQ") CPUID variant however
can "dynamicly" enable rdrand and/or f16c if the host supports them.
Do the same for the avx_and_cx16 ("i5-2300") CPUID variant.

Explicitly make testcase variable for sys-copy_file_range undefined.
On some systems an extra warning could occur when a variable in
the memcheck/tests/linux/sys-copy_file_range testcase was undefined,
but (accidentially) pointed to known bad memory. Fix by defining the
variable as 0, but then marking it explicitly undefined using memcheck
VALGRIND_MAKE_MEM_UNDEFINED.

Fix memcheck/tests/linux/sys-copy_file_range open call (mode).
sys-copy_file_range.c calls open with O_CREAT flag and so must provide
a mode argument. valgrind memcheck actually caught this ommission on
some arches (fedora rawhide i686 specifically).
This is a small additional fixup for

aarch64 (arm64) isn't a supported architecture for exp-sgcheck.
exp-sgcheck/pc_main.c contains:
#if defined(VGA_arm) || defined(VGA_arm64)
VG_(printf)("SGCheck doesn't work on ARM yet, sorry.\n");
VG_(exit)(1);
#endif
But exp-sgcheck/tests/is_arch_supported checked against uname -m
which returns aarch64 (not arm64). Fix the test check so the
exp-sgcheck tests are skipped instead of producing failures.

x86 and amd64 tests: Use .text and .previous around all top-level asm.
GCC10 defaults to -fno-common which exposes some latent bugs in
some of the top-level asm code in various .c test files. Some of the
tests started to segfault (even if not run under valgrind). Such code
needs to be wrapped inside a .text and a .previous asm statement to
make sure the code is generated in the .text code section and to
make sure the compiler doesn't lose track of the section currently
being used to generate data or code in. Without it code might be
generated inside a data section or the other way around.

commit b064131bdf099d3647b4501e5d15391e1e9623e6
Author: Mark Wielaard <mark@klomp.org>
Date: Thu May 30 00:29:58 2019 +0200
linux x86 and amd64 memory protection key syscalls.
This implements minimal support for the pkey_alloc, pkey_free and
pkey_mprotect syscalls. pkey_alloc will simply indicate that pkeys
are not supported. pkey_free always fails. pkey_mprotect works just
like mprotect if the special pkey -1 is provided.

commit b0861063a8d2a55bb7423e90d26806bab0f78a12
Author: Alexandra Hájková <ahajkova@redhat.com>
Date: Tue Jun 4 13:47:14 2019 +0200
Add support for preadv2 and pwritev2 syscalls
Support for amd64, x86 - 64 and 32 bit, arm64, ppc64, ppc64le,
s390x, mips64. This should work identically on all
arches, tested on x86 32bit and 64bit one, but enabled on all.
Refactor the code to be reusable between old/new syscalls. Resolve TODO
items in the code. Add the testcase for the preadv2/pwritev2 and also
add the (similar) testcase for the older preadv/pwritev syscalls.
Trying to test handling an uninitialized flag argument for the v2 syscalls
does not work because the flag always comes out as defined zero.
Turns out glibc does this deliberately on 64bit architectures because
the kernel does actually have a low_offset and high_offset argument, but
ignores the high_offset/assumes it is zero.

commit 3bac39a10abf292d332bb20ab58c6dd5c28f9108
Author: Eugene Syromyatnikov <evgsyr@gmail.com>
Date: Fri Mar 8 04:07:00 2019 +0100
include/vki: fix vki_siginfo_t definition on amd64, arm64, and ppc64
As it turned out, the size of vki_siginfo_t is incorrect on these 64-bit
architectures:
(gdb) p sizeof(vki_siginfo_t)
$1 = 136
(gdb) ptype struct vki_siginfo
type = struct vki_siginfo {
int si_signo;
int si_errno;
int si_code;
union {
int _pad[29];
struct {...} _kill;
struct {...} _timer;
struct {...} _rt;
struct {...} _sigchld;
struct {...} _sigfault;
struct {...} _sigpoll;
} _sifields;
}
It looks like that for this architecture, __VKI_ARCH_SI_PREAMBLE_SIZE
hasn't been defined properly, which resulted in incorrect
VKI_SI_PAD_SIZE calculation (29 instead of 28).
<6a9e4> DW_AT_name : (indirect string, offset: 0xcf59): _sifields
<6a9ef> DW_AT_data_member_location: 16
This issue has been discovered with strace's "make check-valgrind-memcheck",
which produced false out-of-bounds writes on ptrace(PTRACE_GETSIGINFO) calls:
SYSCALL[24264,1](101) sys_ptrace ( 16898, 24283, 0x0, 0x606bd40 )

(Note that the address passed is 0x606bd40 and the address reported is

After the patch, no such errors observed.

From abbd80e7e23deb1f27fb50410c8b3a3f7cdfb646 Mon Sep 17 00:00:00 2001
From: Andreas Arnez <arnez@linux.ibm.com>
Date: Wed, 12 Feb 2020 14:13:55 +0100
Subject: [PATCH] Bug 417452 - s390_insn_store_emit: dst->tag for HRcVec128
It was seen that the s390 instruction selector chose a wrong addressing
mode for storing a vector register. The VST instruction only handles
short (12-bit unsigned) displacements, but a long (20-bit signed)
displacement was generated instead, resulting in a panic:
vex: the `impossible' happened:
s390_insn_store_emit: unknown dst->tag for HRcVec128
The fix prevents long displacements for vector store operations. It also
optimizes vector store operations from an Iex_Get, by converting them to a
memory copy. This optimization was already performed for integer
registers.

From bfa89eae00ba7067445bc0532e1f17405c062954 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Bug 407764 - s390x: drd fails on z13 due to function wrapping
issue
The s390x-specific inline assembly macros for function wrapping in
include/valgrind.h have a few issues.
When the compiler uses vector registers, such as with "-march=z13", all
vector registers must be declared as clobbered by the callee. Because
this is missing, many drd test failures are seen with "-march=z13".
Also, the inline assemblies write the return value into the target
register before restoring r11. If r11 is used as the target register,
this means that the restore operation corrupts the result. This bug
causes failures with memcheck's "wrap6" test case.
These bugs are fixed. The clobber list is extended by the vector
registers (if appropriate), and the target register is now written at the
end, after restoring r11.

Make memcheck/tests/arm64-linux/scalar test work under root.
Running the testsuite as root isn't really recommended.
But lets not make tests fail unnecessarily when running as root.
Pass really invalid arguments to setuid, setgid, acct and fchown.
Make setresgid, setresuid, setregid and setreuid always succeed.

Similar to the arm64-linux/scalar fixes. Plus 32bit variants that

s390x: Add CPU model for z15
Make the z15 CPU models known to Valgrind. Add test case output for z15
to the "ecag" test. Also ensure that the facility bits for CPU facilities
unsupported by Valgrind are unset, particularly for the new
deflate-conversion facility.
