ide/via: Implement and use native PCI IDE mode
This device only implemented ISA compatibility mode and native PCI IDE
mode was missing but no clients actually need ISA mode but to the
contrary, they usually want to switch to and use device in native
PCI IDE mode. Therefore implement native PCI mode and switch default
to that.

ide/via: Rename functions to match device name
The device is called via-ide and the modelled IDE controller is not
specific to 82C686B but is also usable independently. Therefore, change
function name prefixes accordingly to match device name.

currently).

Parts of the SiI3112 mmio are identical to PCI IDE registers so we can
use the corresponding functions that were factored out into ide/pci.c.
This removes code duplication and simplifies the SiI3112 model which
also helped to spot a copy paste error where reading status of the
2nd channel read the 1st channel instead. This is also fixed here.

The cmd646 io mem ops callbacks only need the IDEBus which is
currently passed via a CMD646BAR struct. No need to wrap it up like
that, we can pass it directly to these callbacks which then allows to
drop the IDEBus from the CMD646BAR.

target/mips: Correct the second argument type of cpu_supports_isa()
"insn_flags" bitfield was expanded from 32-bit to 64-bit in commit f9c9cd63e3. However, this was not reflected on the second argument
of the function cpu_supports_isa(). By chance, this did not create
some wrong behavior, since the left-most halves of all instances of
the second argument are currently all zeros. However, this is still
a bug waiting to happen. Correct this by changing the type of the
second argument to be always 64-bit.
Commit 8bca4613 added support for %% in json strings when interpolating,
but in doing so broke handling of % when not interpolating.
When parse_string() is fed a string token containing '%', it skips the
'%' regardless of ctxt->ap, i.e. even it's not interpolating. If the
'%' is the string's last character, it fails an assertion. Else, it
"merely" swallows the '%'.
Fix parse_string() to handle '%' specially only when interpolating.
To gauge the bug's impact, let's review non-interpolating users of this
parser, i.e. code passing NULL context to json_message_parser_init():
Filenames are trusted when they come from command line, QMP or HMP.
They are untrusted when they come from from image file headers.
Example: QCOW2 backing file name. Note that this is *not* the security
boundary between host and guest. It's the boundary between host and an
image file from an untrusted source.
Neither failing an assertion nor skipping a character in a filename of
your choice looks exploitable. Note that we don't support compiling
with NDEBUG.
trace: add ability to do simple printf logging via systemtap
The dtrace systemtap trace backend for QEMU is very powerful but it is
also somewhat unfriendly to users who aren't familiar with systemtap,
or who don't need its power right now.
stap -e "....some strange script...."
The 'log' backend for QEMU by comparison is very crude but incredibly
easy to use:
This commit introduces a way to do simple printf style logging of probe
points using systemtap. In particular it creates another set of tapsets,
one per emulator:
/usr/share/systemtap/tapset/qemu-*-log.stp
These pre-define probe functions which simply call printf() on their
arguments. The printf() format string is taken from the normal
trace-events files, with a little munging to the format specifiers
to cope with systemtap's more restrictive syntax.
We go one step further though and introduce a 'qemu-trace-stap' tool to
make this even easier
$ qemu-trace-stap run qemu-system-x86_64 'qio*'
22806@1547735341399856820 qio_channel_socket_new Socket new ioc=0x56135d1d7c00
22806@1547735341399862570 qio_task_new Task new task=0x56135cd66eb0 source=0x56135d1d7c00 func=0x56135af746c0 opaque=0x56135bf06400

22806@1547735341399976816 qio_task_thread_run Task thread run task=0x56135cd66eb0
This tool is clever in that it will automatically change the
SYSTEMTAP_TAPSET env variable to point to the directory containing the
right set of probes for the QEMU binary path you give it. This is useful
if you have QEMU installed in /usr but are trying to test and trace a
binary in /home/berrange/usr/qemu-git. In that case you'd do
$ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*'
And it'll make sure /home/berrange/usr/qemu-git/share/systemtap/tapset
is used for the trace session
The 'qemu-trace-stap' script takes a verbose arg so you can understand
what it is running
$ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*'
Using tapset dir '/home/berrange/usr/qemu-git/share/systemtap/tapset' for binary '/home/berrange/usr/qemu-git/bin/qemu-system-x86_64'
Compiling script 'probe qemu.system.x86_64.log.qio* {}'
Running script, <Ctrl>-c to quit
...trace output...
It can enable multiple probes at once
$ qemu-trace-stap run qemu-system-x86_64 'qio*' 'qcrypto*' 'buffer*'
By default it monitors all existing running processes and all future
launched proceses. This can be restricted to a specific PID using the
--pid arg
$ qemu-trace-stap run --pid 2532 qemu-system-x86_64 'qio*'
Finally if you can't remember what probes are valid it can tell you
$ qemu-trace-stap list -v qemu-system-x86_64 'qio*'
Using tapset dir '/home/berrange/usr/qemu-git/share/systemtap/tapset' for binary '/home/berrange/usr/qemu-git/bin/qemu-system-x86_64'

trace: forbid use of %m in trace event format strings
The '%m' format instructs glibc's printf()/syslog() implementation to
insert the contents of strerror(errno). Since this is a glibc extension
it should generally be avoided in QEMU due to need for portability to a
variety of platforms.
Even though vfio is Linux-only code that could otherwise use "%m", it
must still be avoided in trace-events files because several of the
backends do not use the format string and so this error information is
invisible to them.
The errno string value should be given as an explicit trace argument
instead, making it accessible to all backends. This also allows it to
work correctly with future patches that use the format string with
systemtap's simple printf code.
trace: enforce that every trace-events file has a final newline
When generating the trace-events-all file, the build system simply
concatenates all the individual trace-events files. If any one of those
files does not have a final newline, the printf format string will have
the contents of the first line of the next file appended to it, which is
usually a '#' comment.
display: ensure qxl log_buf is a nul terminated string
The QXL_IO_LOG command allows the guest to send log messages to the host
via a buffer in the QXLRam struct. QEMU prints these to the console if
the qxl 'guestdebug' option is set to non-zero. It will also feed them
to the trace subsystem if any backends are built-in.
In both cases the log_buf data will get treated as being as a nul
terminated string, by the printf '%s' format specifier and / or other
code reading the buffer.
QEMU does nothing to guarantee that the log_buf really is nul terminated,
so there is potential for out of bounds array access.
This would affect any QEMU which has the log, syslog or ftrace trace
backends built into QEMU. It can only be triggered if the 'qxl_io_log'
trace event is enabled, however, so they are not vulnerable without
specific administrative action to enable this.
It would also affect QEMU if the 'guestdebug' parameter is set to a
non-zero value, which again is not the default and requires explicit
admin opt-in.

io: ensure UNIX client doesn't unlink server socket
The qio_channel_socket_close method for was mistakenly unlinking the
UNIX server socket, even if the channel was a client connection. This
was not noticed with chardevs, since they never call close, but with the
VNC server, this caused the VNC server socket to be deleted after the
first client quit.
The qio_channel_socket_close method also needlessly reimplemented the
logic that already exists in socket_listen_cleanup(). Just call that
method directly, for listen sockets only.

The backtrace involves the queue restart coroutine where
tgm->throttle_state is a NULL pointer because

This coroutine should not execute in the iothread after the throttle
group member has been unregistered!
The root cause is that the device_del code path schedules the restart
coroutine in the iothread while holding the AioContext lock. Therefore
the iothread cannot execute the coroutine until after device_del
releases the lock - by this time it's too late.
This patch adds a reference count to ThrottleGroupMember so we can
synchronously wait for restart coroutines to complete. Once they are
done it is safe to unregister the ThrottleGroupMember.
The user can pick any of these key combinations. The VM's grab
of the evdev device will be toggled when the key combination is
pressed.
Any invalid setting will result in an error. No setting will
result in the current default of ctrl-ctrl.
The right and left ctrl key both work for Ctrl-Scrolllock.
If scrolllock is selected as one of the grab-toggle keys, it
will be entirely disabled and not passed to the guest at all.
This is to prevent enabling it while attempting to leave or enter
the VM. On the host, scrolllock can be disabled using xmodmap.
First, find the modifier that Scroll_Lock is bound to:
$ xmodmap -pm
Then, remove Scroll_Lock from it, replacing modX with the modifier:
$ xmodmap -e 'remove modX = Scroll_Lock'
If Scroll_Lock is not bound to any modifier, it is already disabled.
To save the changes, add them to your xinitrc.

qapi: Eliminate indirection through qmp_event_get_func_emit()
The qapi_event_send_FOO() functions emit events like this:
QMPEventFuncEmit emit;
emit = qmp_event_get_func_emit();
if (!emit) {
return;
}
qmp = qmp_event_build_dict("FOO");
[put event arguments into @qmp...]
emit(QAPI_EVENT_FOO, qmp);
The value of qmp_event_get_func_emit() depends only on the program:
* In qemu-system-FOO, it's always monitor_qapi_event_queue.
* In tests/test-qmp-event, it's always event_test_emit.
* In all other programs, it's always null.
This is exactly the kind of dependence the linker is supposed to
resolve; we don't actually need an indirection.
Note that things would fall apart if we linked more than one QAPI
schema into a single program: each set of qapi_event_send_FOO() uses
its own event enumeration, yet they share a single emit function.
Which takes the event enumeration as an argument. Which one if
there's more than one?
More seriously: how does this work even now? qemu-system-FOO wants
QAPIEvent, and passes a function taking that to
qmp_event_set_func_emit(). test-qmp-event wants test_QAPIEvent, and
passes a function taking that to qmp_event_set_func_emit().
We use unsigned instead of the enumeration type. Relies on both
enumerations boiling down to unsigned, which happens to be true for
the compilers we use.
Clean this up as follows:
* Generate qapi_event_send_FOO() that call PREFIX_qapi_event_emit()
instead of the value of qmp_event_set_func_emit().
* Generate a prototype for PREFIX_qapi_event_emit() into
qapi-events.h.
* PREFIX_ is empty for qapi/qapi-schema.json, and test_ for
tests/qapi-schema/qapi-schema-test.json. It's qga_ for
qga/qapi-schema.json, and doc-good- for
tests/qapi-schema/doc-good.json, but those don't define any events.
* Rename monitor_qapi_event_queue() to qapi_event_emit() instead of
passing it to qmp_event_set_func_emit(). This takes care of
qemu-system-FOO.
* Rename event_test_emit() to test_qapi_event_emit() instead of
passing it to qmp_event_set_func_emit(). This takes care of
tests/test-qmp-event.
* Add a qapi_event_emit() that does nothing to stubs/monitor.c. This
takes care of all other programs that link code emitting QMP events.
* Drop qmp_event_set_func_emit(), qmp_event_get_func_emit().

some of the extF80 and f128 related tests. Once we re-factor and fix
these tests the plumbing should get simpler.

include/fpu/softfloat: Fix compilation with Clang on s390x
Clang v7.0.1 does not like the __int128 variable type for inline
assembly on s390x:
In file included from fpu/softfloat.c:97:
include/fpu/softfloat-macros.h:647:9: error: inline asm error:
This value type register class is not natively supported!
asm("dlgr %0, %1" : "+r"(n) : "r"(d));
^
Disable this code part there now when compiling with Clang, so that
the generic code gets used instead.

softfloat: enforce softfloat if the host's FMA is broken
The added branch to the FMA ops is marked as unlikely and therefore
its impact on performance (measured with fp-bench) is within noise range
when measured on an Intel(R) Xeon(R) Gold 6142 CPU @ 2.60GHz.

fp-bench: remove wrong exponent raise in fill_random
At this point random_ops[] only contains normals, so there's
no need to do anything to them. In fact, raising the exponent
here can make the output !normal, which is precisely
what the comment says we want to avoid.

target/microblaze: Switch to transaction_failed hook
Switch the microblaze target from the old unassigned_access hook
to the transaction_failed hook.
The notable difference is that rather than it being called
for all physical memory accesses which fail (including
those made by DMA devices or by the gdbstub), it is only
called for those made by the CPU via its MMU. For
microblaze this makes no difference because none of the
target CPU code needs to make loads or stores by physical
address.
