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

commit 59784c512ec40e588b21cf5ae8e31e9c4f99d6b8

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.

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.

Hook up preadv2 and pwritev2 correctly for arm64.
Use the correct generic linux sys wrapper.

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
don't exist on arm64.
Pass really invalid arguments to setuid[32], setgid[32], acct, fchown[32].
Make setresgid[32], setresuid[32], setregid[32], setreuid[32] always succeed.

commit fb6f7abcbc92506d302fb18a2c5fc853d2929248
Author: Carl Love <cel@us.ibm.com>
Date: Tue Jun 9 10:42:03 2020 -0500
Power PC Fix extraction of the L field for sync instruction
The L field is currently a two bit[22:21] field in ISA 3.0. The size of the
L field has changed over time.
Currently the ISA 3.0 Valgrind sync instruction support code sets the
flag_L for the instruction L field to a five bit value that includes bits
that are marked reserved the sync instruction. This patch fixes the issue for ISA 3.0
to only setting flag_L the specified two bits.
