If the tracefs mountpoint has a very long path we may exceed PATH_MAX.
This is a system misconfiguration and the user must resolve it so that
applications can perform path-based system calls successfully.
This issue does not occur on real-world systems since tracefs is mounted
on /sys/kernel/debug/tracing/, but the compiler is smart enough to
foresee the possibility and warn about the unchecked snprintf(3) return
value. This patch fixes the compiler warning.

While running the GCC test suite against 4.0.0-rc0, Kito found a
regression introduced by the decodetree conversion that caused divuw and
remuw to sign-extend their inputs. The ISA manual says they are
supposed to be zero extended:
DIVW and DIVUW instructions are only valid for RV64, and divide the
lower 32 bits of rs1 by the lower 32 bits of rs2, treating them as
signed and unsigned integers respectively, placing the 32-bit
quotient in rd, sign-extended to 64 bits. REMW and REMUW
instructions are only valid for RV64, and provide the corresponding
signed and unsigned remainder operations respectively. Both REMW
and REMUW always sign-extend the 32-bit result to 64 bits, including
on a divide by zero.
Here's Kito's reduced test case from the GCC test suite
unsigned calc_mp(unsigned mod)
{
unsigned a,b,c;
c=-1;
a=c/mod;
b=0-a*mod;
if (b > mod) { a += 1; b-=mod; }
return b;
}
int main(int argc, char *argv[])
{
unsigned x = 1234;
unsigned y = calc_mp(x);
if ((sizeof (y) == 4 && y != 680)
|| (sizeof (y) == 2 && y != 134))
abort ();
exit (0);
}
I haven't done any other testing on this, but it does fix the test case.

break_dependency incorrectly handles the case of dependency on an opcode
that references the same register multiple times. E.g. the following
instruction is translated incorrectly:
{ or a2, a3, a3 ; or a3, a2, a2 }
This happens because resource indices of both dependency graph nodes are
incremented, and a copy for the second instance of the same register in
the ending node is not done.
Only increment resource index of the ending node of the dependency.
Add test.

When virtio-vga was added, the intention was to only support it for
those machines where the firmware does not know about virtio-gpu,
and supported VGA legacy hardware before virtio-{gpu,vga} were
introduced.
The Kconfig switch however enabled virtio-vga for all machines with
a PCI bus, and libvirt then prefers it even on hardware where
virtio-gpu would be preferrable. At least for now, only enable
virtio-vga for PC, hppa and pSeries machines, as was the case
before Kconfig dependencies were introduced.

We were never reporting the G_IO_HUP event when an end of file was hit
on the websocket channel.
We also didn't report G_IO_ERR when we hit a fatal error processing the
websocket protocol.
The latter in particular meant that the chardev code would not notice
when an eof/error was encountered on the websocket channel, unless the
guest OS happened to trigger a write operation.
This meant that once the first client had quit, the chardev would never
listen to accept a new client.

The docs currently say that the spec-ctrl feature is needed for both
Spectre variants, but it is only used to address Spectre v2. Also
remove the note about retpolines. The guest OS is usually treated
as a blackbox from host mgmt pov, so it won't have knowledge about
use of retpolines and thus should unconditionally expose spec-ctrl,
allowing the guest to decide whether to use it or not.

Currently, the Cascadelake-Server, Icelake-Client, and
Icelake-Server are always generating the following warning:
qemu-system-x86_64: warning: \
host doesn't support requested feature: CPUID.07H:ECX [bit 4]
This happens because OSPKE was never returned by
GET_SUPPORTED_CPUID or x86_cpu_get_supported_feature_word().
OSPKE is a runtime flag automatically set by the KVM module or by
TCG code, was always cleared by x86_cpu_filter_features(), and
was not supposed to appear on the CPU model table.
Remove the OSPKE flag from the CPU model table entries, to avoid
the bogus warning and avoid returning invalid feature data on
query-cpu-* QMP commands. As OSPKE was always cleared by
x86_cpu_filter_features(), this won't have any guest-visible
impact.
Include a test case that should detect the problem if we introduce
a similar bug again.

KVM has two bugs in the handling of MSR_IA32_ARCH_CAPABILITIES:
1) Linux commit commit 1eaafe91a0df ("kvm: x86: IA32_ARCH_CAPABILITIES
is always supported") makes GET_SUPPORTED_CPUID return
arch_capabilities even if running on SVM. This makes "-cpu
host,migratable=off" incorrectly expose arch_capabilities on CPUID on
AMD hosts (where the MSR is not emulated by KVM).
2) KVM_GET_MSR_INDEX_LIST does not return MSR_IA32_ARCH_CAPABILITIES if
the MSR is not supported by the host CPU. This makes QEMU not
initialize the MSR properly at kvm_put_msrs() on those hosts.
Work around both bugs on the QEMU side, by checking if the MSR
was returned by KVM_GET_MSR_INDEX_LIST before returning the
feature flag on kvm_arch_get_supported_cpuid().
This has the unfortunate side effect of making arch_capabilities
unavailable on hosts without hardware support for the MSR until bug #2
is fixed on KVM, but I can't see another way to work around bug #1
without that side effect.

Previously we have per-device system memory aliases when DMAR is
disabled by the system. It will slow the system down if there are
lots of devices especially when DMAR is disabled, because each of the
aliased system address space will contain O(N) slots, and rendering
such N address spaces will be O(N^2) complexity.
This patch introduces a shared nodmar memory region and for each
device we only create an alias to the shared memory region. With the
aliasing, QEMU memory core API will be able to detect when devices are
sharing the same address space (which is the nodmar address space)
when rendering the FlatViews and the total number of FlatViews can be
dramatically reduced when there are a lot of devices.

xen-mapcache: use MAP_FIXED flag so the mmap address hint is always honored
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Or if it's not possible to honor the hinted address an error is returned
instead. This makes it easier to spot the actual failure, instead of
failing later on when the caller of xen_remap_bucket realizes the
mapping has not been created at the requested address.
Also note that at least on FreeBSD using MAP_FIXED will cause mmap to
try harder to honor the passed address.

There is no reason why the constraints we put on @replaces should be
limited to drive-mirror. Therefore, move the sanity checks from
qmp_drive_mirror() to blockdev_mirror_common() so they apply to
blockdev-mirror as well.

Job (especially mirror) may call block_job_error_action several
times before actual pause if it has several in-flight requests.
block_job_error_action will call job_pause more than once in this case,
which lead to following block-job-resume qmp command can't actually
resume the job.
Fix it by do not increase pause level in block_job_error_action if
user_paused already set.

232 is marked as generic, but commit 12efe428c9 added code that assumes
qcow2. What the new test really needs is backing files and support for
updating the backing file link (.bdrv_change_backing_file).
Split the non-generic code into a new test case 247 and make it work
with qed, too.

Recent commit cda4aa9a5a moved block backend creation before machine
property evaluation. This broke qemu-iotests 055. Turns out we need
to create the migration object before block backends, so block
backends can add migration blockers. Fix by calling
migration_object_init() earlier, right before configure_blockdev().

There are various actions in this test that must be executed
sequentially, as the result of it depends on the state triggered by the
previous one.
If the last argument of _send_qemu_cmd() is an empty string, it just
sends the QMP commands without waiting for an answer. While unlikely, it
may happen that the next action in the test gets invoked before QEMU
processes the QMP request.
This issue seems to be easier to reproduce on servers with limited
resources or highly loaded.
With this change, we wait for an answer on all _send_qemu_cmd() calls.

Coverity doesn't like that the return value of bdrv_check_update_perm()
stays unused only in this place (CID 1399710).
Even if checking local_err should be equivalent to checking ret < 0,
let's switch to using the return value to be more consistent (and in
case of a bug somewhere down the call chain, forgetting to assign errp
is more likely than returning 0 for an error case).

Commit 509d39aa22 added support for read
only VMDKs of version 3.
This commit fixes the probe function to correctly handle descriptors of
version 3.
This commit has two effects:
1. We no longer need to supply '-f vmdk' when pointing to descriptor
files of version 3 in qemu/qemu-img command line arguments.
2. This fixes the scenario where a VMDK points to a parent version 3
descriptor file which is being probed as "raw" instead of "vmdk".
