In the ->inactivate() callbacks, permissions are updated, which
typically involves a recursive check of the whole graph. Setting
BDRV_O_INACTIVE right before doing that creates a state that
bdrv_is_writable() returns false, which causes permission update
failure.
Reorder them so the flag is updated after calling the function. Note
that this doesn't break the assert in bdrv_child_cb_inactivate() because
for any specific BDS, we still update its flags first before calling
->inactivate() on it one level deeper in the recursion.

ppc patch queue 2017-08-23
This is identical to the pull request from yesterday (20180822),
except that a bug in one patch is fixed so that it doesn't break TCG
on a ppc host.
Last minute ppc related fixes for qemu-2.10. I'm not sure if these
are critical enough to prompt another rc, but I'm submitting them for
consideration.
First, is Cornelia's fix for 480bc11e6 which meant "make check" would
always fail on a ppc host. Tracking that down delayed submission of
the rest of these patches, sorry.
The rest are all fairly important bugfixes for qemu crashes or guest
behaviour regression on ppc. Patches 2-4 specifically are fixes for
regressions from qemu-2.9, caused by the compatibility mode and
hotplug handling cleanups for the pseries machine type.

QEMU currently crashes when trying to use a 'pc-dimm' on the pseries
machine without specifying its 'memdev' property. This happens because
pc_dimm_get_memory_region() does not check whether the 'memdev' property
has properly been set by the user. Looking closer at this function, it's
also obvious that it is using &error_abort to call another function - and
this is bad in a function that is used in the hot-plugging calling chain
since this can also cause QEMU to exit unexpectedly.
So let's fix these issues in a proper way now: Add a "Error **errp"
parameter to pc_dimm_get_memory_region() which we use in case the 'memdev'
property has not been set by the user, and which we can use instead of
the &error_abort, and change the callers of get_memory_region() to make
use of this "errp" parameter for proper error checking.

In case of in-kernel memory hot unplug, when the guest is not able
to remove all the LMBs that are requested for removal, it will add back
any LMBs that have been successfully removed. The DR Connectors of
these LMBs wouldn't have been unconfigured and hence the addition of
these LMBs will result in configure-connector call being issued on
LMB DR connectors that are already in configured state. Such
configure-connector calls will fail resulting in a DIMM which is
partially unplugged.
This however worked till recently before we overhauled the DRC
implementation in QEMU. Commit 9d4c0f4f0a71e: "spapr: Consolidate
DRC state variables" is the first commit where this problem shows up
as per git bisect.
Ideally guest shouldn't be issuing configure-connector call on an
already configured DR connector. However for now, work around this in
QEMU by allowing configure-connector to be called multiple times for
all types of DR connectors.

When running in KVM PR mode, kvmppc_set_compat() always fail because the
current PR implementation doesn't handle KVM_REG_PPC_ARCH_COMPAT. Now that
the machine code inconditionally calls ppc_set_compat_all() at reset time
to restore the compat mode default value (commit 66d5c492dd3a9), it is
impossible to start a guest with PR:
qemu-system-ppc64: Unable to set CPU compatibility mode in KVM:
Invalid argument
A tentative patch [1] was recently sent by Suraj to address the issue, but
it would prevent the compat mode to be turned off on reset. And we really
don't want to explicitely check for KVM PR. During the patch's review,
David suggested that we should only call the KVM ioctl() if the compat
PVR changes. This allows at least to run with KVM PR, provided no compat
mode is requested from the command line (which should be the case when
running PR nested). This is what this patch does.
While here, we also fix the side effect where KVM would fail but we would
change the CPU state in QEMU anyway.

Commit d5fc133eed ("ppc: Rework CPU compatibility testing
across migration") changed the way cpu_post_load behaves with
the PVR setting, causing an unexpected bug in KVM-HV migrations
between hosts that are compatible (POWER8 and POWER8E, for example).
Even with pvr_match() returning true, the guest freezes right after
cpu_post_load. The reason is that the guest kernel can't handle a
different PVR value other that the running host in KVM_SET_SREGS.
In [1] it was discussed the possibility of a new KVM capability
that would indicate that the guest kernel can handle a different
PVR in KVM_SET_SREGS. Even if such feature is implemented, there is
still the problem with older kernels that will not have this capability
and will fail to migrate.
This patch implements a workaround for that scenario. If running
with KVM, check if the guest kernel does not have the capability
(named here as 'cap_ppc_pvr_compat'). If it doesn't, calls
kvmppc_is_pr() to see if the guest is running in KVM-HV. If all this
happens, set env->spr[SPR_PVR] to the same value as the current
host PVR. This ensures that we allow migrations with 'close enough'
PVRs to still work in KVM-HV but also makes the code ready for
this new KVM capability when it is done.
A new function called 'kvmppc_pvr_workaround_required' was created
to encapsulate the conditions said above and to avoid calling too
many kvm.c internals inside cpu_post_load.

The mmio-interface device is not something we want to allow
users to create on the command line:
* it is intended as an implementation detail of the memory
subsystem, which gets created and deleted by that
subsystem on demand; it makes no sense to create it
by hand on the command line
* it uses a pointer property 'host_ptr' which can't be
set on the command line
Mark the device as not user_creatable to avoid confusion.

At the same time, leave the entire 64-bit value in cpu_exclusive_val
and stop writing to cpu_exclusive_high. This means that we do not
have to re-assemble the 64-bit quantity when it comes time to store.
At the same time, drop a redundant temporary and perform all loads

When we switched NBD to use coroutines for qemu 2.9 (in particular,
commit a12a712a), we introduced a regression: if a server sends us
garbage (such as a corrupted magic number), we quit the read loop
but do not stop sending further queued commands, resulting in the
client hanging when it never reads the response to those additional
commands. In qemu 2.8, we properly detected that the server is no
longer reliable, and cancelled all existing pending commands with
EIO, then tore down the socket so that all further command attempts
get EPIPE.
Restore the proper behavior of quitting (almost) all communication
with a broken server: Once we know we are out of sync or otherwise
can't trust the server, we must assume that any further incoming
data is unreliable and therefore end all pending commands with EIO,
and quit trying to send any further commands. As an exception, we
still (try to) send NBD_CMD_DISC to let the server know we are going
away (in part, because it is easier to do that than to further
refactor nbd_teardown_connection, and in part because it is the
only command where we do not have to wait for a reply).
Based on a patch by Vladimir Sementsov-Ogievskiy.
A malicious server can be created with the following hack,
followed by setting NBD_SERVER_DEBUG to a non-zero value in the
environment when running qemu-nbd:

The 093 throttling test submits twice as many requests as the throttle
limit in order to ensure that we reach the limit. The remaining
requests are left in-flight at the end of each test iteration.
Commit 452589b6b47e8dc6353df257fc803dfc1383bed8 ("vl.c/exit: pause cpus
before closing block devices") exposed a hang in 093. This happens
because requests are still in flight when QEMU terminates but
QEMU_CLOCK_VIRTUAL time is frozen. bdrv_drain_all() hangs forever since
throttled requests cannot complete.
Step the clock at the end of each test iteration so in-flight requests
actually finish. This solves the hang and is cleaner than leaving tests
in-flight.
Note that this could also be "fixed" by disabling throttling when drives
are closed in QEMU. That approach has two issues:
1. We must drain requests before disabling throttling, so the hang
cannot be easily avoided!
2. Any time QEMU disables throttling internally there is a chance that
malicious users can abuse the code path to bypass throttling limits.
Therefore it makes more sense to fix the test case than to modify QEMU.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

The simpletrace.py script can pretty-print flight recorder ring buffers.
These are not full simpletrace binary trace files but just the end of a
trace file. There is no header and the event ID mapping information is
often unavailable since the ring buffer may have filled up and discarded
event ID mapping records.
The simpletrace.stp script that generates ring buffer traces uses the
same trace-events-all input file as simpletrace.py. Therefore both
scripts have the same global ordering of trace events. A dynamic event
ID mapping isn't necessary: just use the trace-events-all file as the
reference for how event IDs are numbered.
It is now possible to analyze simpletrace.stp ring buffers again using:
$ ./simpletrace.py trace-events-all path/to/ring-buffer

This is a partial revert of commit
7f1b588f20d027730676e627713ae3bbf6baab04 ("trace: emit name <-> ID
mapping in simpletrace header"), which broke the SystemTap flight
recorder because event mapping records may not be present in the ring
buffer when the trace is analyzed. This means simpletrace.py
--no-header does not know the event ID mapping needed to pretty-print
the trace.
Instead of numbering events dynamically, use a static event ID mapping
as dictated by the event order in the trace-events-all file.
The simpletrace.py script also uses trace-events-all so the next patch
will fix the simpletrace.py --no-header option to take advantage of this
knowledge.

Currently if you do "make check-help" in a fresh checkout, only an error
is printed which is not nice:
$ make check-help V=1
cc -nostdlib -o check-help.mo
cc: fatal error: no input files
compilation terminated.
rules.mak:115: recipe for target 'check-help.mo' failed
make: *** [check-help.mo] Error 1
Move the config-host.mak condition into the body of
tests/Makefile.include and always include the rule for check-help.

This reverts a change that replaced the "rm -f" command with the
undefined variable RM (expected to be set by make), and causes the
"make clean" command to fail for a s390 target:
make[1]: Entering directory '/usr/src/qemu/build/pc-bios/s390-ccw'
rm -f *.timestamp
*.o *.d *.img *.elf *~ *.a
/bin/sh: *.o: command not found

This adds mmio-exec property to workaround the migration bug.
When enabled the migration is blocked and will return an error.

The two HMP commands host_net_add and -remove have recently been
marked as deprecated, too, so we should now mention them in the

QEMU currently abort()s if the user tries to specify the mmio_interface
device without parameters:
x86_64-softmmu/qemu-system-x86_64 -nographic -device mmio_interface
qemu-system-x86_64: /home/thuth/devel/qemu/util/error.c:57: error_setv:
Assertion `*errp == ((void *)0)' failed.
Aborted (core dumped)
This happens because the realize function is trying to set the errp
twice in this case. After setting an error, the realize function
should immediately return instead.

The check script contains a commented out root user requirement,
probably because of its xfstests heritage. This requirement doesn't
apply to qemu-iotests, so it better be gone.

The variables FULL_MKFS_OPTIONS and FULL_MOUNT_OPTIONS are commented
out, never used, and even refer to functions that do exist. The last
time these were touched was around 8 years ago, so I guess it's safe
to assume outputting such information on test execution is still on the
radar.

Although this function is used, its implementation does nothing
besides echoing a variable name. There's no need to wrap this
functionality in a function, and based on the one usage it has, it's
not even required to adhere to a convention or code style.

While Andrew S. Tanenbaum has a point by saying "Never underestimate the
bandwidth of a station wagon full of tapes hurtling down the highway",
we don't support that way of transportation in QEMU yet, so replace the
typo with the correct word "vlan".
