In this short queue we have a fix in the sam460ex machine where we're
not storing all GPIO lines in sam460ex_init().
This is not causing problems (as far as we're aware of) at this moment,
but this is getting in the way of a ppc405 rework we want to do for 7.2,
so let's fix it now.

hw/ppc: sam460ex.c: store all GPIO lines in mal_irqs[]
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
We're not storing all GPIO lines we're retrieving with
qdev_get_gpio_in() in mal_irqs[]. We're storing just the last one in the
first index:
for (i = 0; i < ARRAY_SIZE(mal_irqs); i++) {
mal_irqs[0] = qdev_get_gpio_in(uic[2], 3 + i);
}
ppc4xx_mal_init(env, 4, 16, mal_irqs);
mal_irqs is used in ppc4xx_mal_init() to assign the IRQs to MAL:
for (i = 0; i < 4; i++) {
mal->irqs[i] = irqs[i];
}
Since only irqs[0] has been initialized, mal->irqs[1,2,3] are being
zeroed.
This doesn´t seem to trigger any apparent issues at this moment, but
Cedric's QOMification of the MAL device [1] is executing a
sysbus_connect_irq() that will fail if we do not store all GPIO lines
properly.

We currently require at least GCC 7.4 or Clang 6.0 for compiling QEMU.
GCC has __builtin_mul_overflow since version 5 already, and Clang 6.0
also provides this built-in function (see its documentation on this page:
https://releases.llvm.org/6.0.0/tools/clang/docs/LanguageExtensions.html ).

We are having bunch of issues with killpriv_v2 enabled by default. First
of all it relies on clearing suid/sgid bits as needed by dropping
capability CAP_FSETID. This does not work for remote filesystems like
NFS (and possibly others).
Secondly, we are noticing other issues related to clearing of SGID
which leads to failures for xfstests generic/355 and generic/193.
Thirdly, there are other issues w.r.t caching of metadata (suid/sgid)
bits in fuse client with killpriv_v2 enabled. Guest can cache that
data for sometime even if cleared on server.
Second and Third issue are fixable. Just that it might take a little
while to get it fixed in kernel. First one will probably not see
any movement for a long time.
Given these issues, killpriv_v2 does not seem to be a good candidate
for enabling by default. We have already disabled it by default in
rust version of virtiofsd.
Hence this patch disabled killpriv_v2 by default. User can choose to
enable it by passing option "-o killpriv_v2".

When we use BLK_MIG_BLOCK_SIZE in expressions like
block_mig_state.submitted * BLK_MIG_BLOCK_SIZE, this multiplication
is done as 32 bits, because both operands are 32 bits. Coverity
complains about possible overflows because we then accumulate that
into a 64 bit variable.
Define BLK_MIG_BLOCK_SIZE as unsigned long long using the ULL suffix.
The only two current uses of it with this problem are both in
block_save_pending(), so we could just cast to uint64_t there, but
using the ULL suffix is simpler and ensures that we don't
accidentally introduce new variants of the same issue in future.

Coverity complains that when we use the return value from
migrate_multifd_compression() as an array index:
multifd_recv_state->ops = multifd_ops[migrate_multifd_compression()];
that this might overrun the array (which is declared to have size
MULTIFD_COMPRESSION__MAX). This is because the function return type
is MultiFDCompression, which is an autogenerated enum. The code
generator includes the "one greater than the maximum possible value"
MULTIFD_COMPRESSION__MAX in the enum, even though this is not
actually a valid value for the enum, and this makes Coverity think
that migrate_multifd_compression() could return that __MAX value and
index off the end of the array.
Suppress the Coverity error by asserting that the value we're going
to return is within range.

For certain paths in /proc, the open syscall is intercepted and the
returned file descriptor points to a temporary file with emulated
contents.
If TMPDIR is not accessible or writable for the current user (for
example in a read-only mounted chroot or container) tools such as ps
from procps may fail unexpectedly. Trying to read one of these paths
such as /proc/self/stat would return an error such as ENOENT or EROFS.
To relax the requirement on a writable TMPDIR, use memfd_create()
instead to create an anonymous file and return its file descriptor.

For small disk images (<4 GiB), QEMU and SeaBIOS default to the
LARGE/ECHS disk translation method, but it is not uncommon for other
BIOS software to use LBA in these cases as well. Some operating
system boot loaders (e.g., NT 4) do not handle LARGE translations
outside of fixed configurations. See, e.g., Q154052:
"When starting an x86 based computer, Ntdetect.com retrieves and
stores Interrupt 13 information. . . If the disk controller is using a
32 sector/64 head translation scheme, this boundary will be 1 GB. If
the controller uses 63 sector/255 head translation [AUTHOR: i.e.,
LBA], the limit will be 4 GB."
To accommodate these situations, hd_geometry_guess() now follows the
disk translation specified by the user even when the ATA disk geometry
is guessed.
hd_geometry_guess():
* Only set the disk translation when translation is AUTO.
* Show the soon-to-be active translation (*ptrans) in the trace rather
than what was guessed.

Because we weren't setting this flag, our probe of ID_AA64ZFR0
was always returning zero. This also obviates the adjustment
of ID_AA64PFR0, which had sanitized the SVE field.
The effects of the bug are not visible, because the only thing that
ID_AA64ZFR0 is used for within qemu at present is tcg translation.
The other tests for SVE within KVM are via ID_AA64PFR0.SVE.

kvm_dirty_ring_supported() only checks whether the dirty ring support
is available on the x86 host, but it ignores whether the target QEMU
architecture is x86 or not. Thus the test_vcpu_dirty_limit() test
currently fails with the assert((strcmp(arch, "x86_64") == 0)) statement
in dirtylimit_start_vm() if the users run e.g. "make check-qtest-aarch64"
on their x86 host. Fix it by only executing the tests when we're running
with a x86_64 target QEMU binary with KVM.

A MachineState object is used as a owner of the RAM region and this
asserts in memory_region_init_ram() when QEMU is built with
CONFIG_QOM_CAST_DEBUG :
/* This will assert if owner is neither NULL nor a DeviceState.
* We only want the owner here for the purposes of defining a
* unique name for migration. TODO: Ideally we should implement
* a naming scheme for Objects which are not DeviceStates, in
* which case we can relax this restriction.
*/
owner_dev = DEVICE(owner);
Use the BMC and BIC objects as the owners of their memory regions.

In one case:
memcpy(sid->inmsg + sid->inlen, buf, len);
if len == 0 then sid->inmsg + sig->inlen can point to one past the inmsg
array if the array is full. We have to allow len == 0 due to some
vagueness in the spec, but we don't have to call memcpy.
Found by Coverity. This is not a problem in practice, but the results
are technically (maybe) undefined. So make Coverity happy.
