9254893882 qmp: Split ShutdownCause host-qmp into quit and system-reset
It is interesting to know whether the shutdown cause was 'quit' or
'reset', especially when using "--no-reboot". In that case, a management
layer can now determine if the guest wanted a reboot or shutdown, and
can act accordingly.

Changes the output of the reason in the iotests from 'host-qmp' to
'host-qmp-quit'. This does not break compatibility because
the field was introduced in the same version.

ecd7a0d5bb qmp: Add reason to SHUTDOWN and RESET events
This makes it possible to determine what the exact reason was for
a RESET or a SHUTDOWN. A management layer might need the specific reason
of those events to determine which cleanups or other actions it needs to do.

This patch also updates the iotests to the new expected output that includes
the reason.

273e3d92cf tests/acpi-utils: Drop dependence on global_qtest
As a general rule, we prefer avoiding implicit global state
because it makes code harder to safely copy and paste without
thinking about the global state.  Adjust the helper code to
use explicit state instead, and update all callers.

bios-tables-test no longer depends on global_qtest, now that it
passes explicit state through the testsuite data; an assert
proves this fact (although we will get rid of it later, once
global_qtest is gone).

24c01ffa9d ivshmem-test: Drop dependence on global_qtest
Managing parallel connections to two different monitors via
the implicit global_qtest makes it hard to copy-and-paste code
to tests that are not aware of the implicit state.  Since we
have already fixed qpci to avoid global_qtest, we can now
simplify by not using global_qtest anywhere in ivshmem-test.

We can assert that the conversion is correct by checking that
global_qtest remains NULL throughout the test (a later patch
that changes global_qtest to not be a public global variable
will drop the assertions).

0012eb98f1 tests/test-arm-mptimer: Don't leak string memory
The test-arm-mptimer setup creates a lot of test names using
g_strdup_printf() and never frees them. This is entirely
harmless since it's one-shot test code, but it clutters
up the output from clang's LeakSanitizer. Refactor to
use a helper function so we can free the memory.

8eb4b07b6f block: Remove assertions from update_flags_from_options()
This function takes four options (cache.direct, cache.no-flush,
read-only and auto-read-only) from a QemuOpts object and updates the
flags accordingly.

If any of those options is not set (because it was missing from the
original QDict or because it had an invalid value) then the function
aborts with a failed assertion:

   $ qemu-io -c 'reopen -o read-only=foo' hd.qcow2
   block.c:1126: update_flags_from_options: Assertion `qemu_opt_find(opts, BDRV_OPT_CACHE_DIRECT)' failed.
   Aborted

This assertion is unnecessary, and it forces any caller of
bdrv_reopen() to pass all the aforementioned four options. This may
have made sense in order to remove ambiguity when bdrv_reopen() was
taking both flags and options, but that's not the case anymore.

It's also unnecessary if we want to validate the option values,
because bdrv_reopen_prepare() already takes care of that, as we can
see if we remove the assertions:

   $ qemu-io -c 'reopen -o read-only=foo' hd.qcow2
   Parameter 'read-only' expects 'on' or 'off'

dc900c3523 qemu-io: Put flag changes in the options QDict in reopen_f()
When reopen_f() puts a block device in the reopen queue, some of the
new options are passed using a QDict, but others ("read-only" and the
cache options) are passed as flags.

This patch puts those flags in the QDict. This way the flags parameter
becomes redundant and we'll be able to get rid of it in a subsequent
patch.

members from str to QAPISchemaMember, but we still print only a

c9fba9de89 qapi: Rewrite string-input-visitor's integer and list parsing
The input visitor has some problems right now, especially
- unsigned type "Range" is used to process signed ranges, resulting in
  inconsistent behavior and ugly/magical code
- uint64_t are parsed like int64_t, so big uint64_t values are not
  supported and error messages are misleading
- lists/ranges of int64_t are accepted although no list is parsed and
  we should rather report an error
- lists/ranges are preparsed using int64_t, making it hard to
  implement uint64_t values or uint64_t lists
- types that don't support lists don't bail out
- visiting beyond the end of a list is not handled properly
- we don't actually parse lists, we parse *sets*: members are sorted,
  and duplicates eliminated

So let's rewrite it by getting rid of usage of the type "Range" and
properly supporting lists of int64_t and uint64_t (including ranges of
both types), fixing the above mentioned issues.

Lists of other types are not supported and will properly report an
error. Virtual walks are now supported.

Tests have to be fixed up:
- Two BUGs were hardcoded that are fixed now
- The string-input-visitor now actually returns a parsed list and not
  an ordered set.

Please note that no users/callers have to be fixed up. Candidates using
visit_type_uint16List() and friends are:
- backends/hostmem.c:host_memory_backend_set_host_nodes()
-- Code can deal with duplicates/unsorted lists
- numa.c::query_memdev()
-- via object_property_get_uint16List(), the list will still be sorted
   and without duplicates (via host_memory_backend_get_host_nodes())
- qapi-visit.c::visit_type_Memdev_members()
- qapi-visit.c::visit_type_NumaNodeOptions_members()
- qapi-visit.c::visit_type_RockerOfDpaGroup_members
- qapi-visit.c::visit_type_RxFilterInfo_members()
-- Not used with string-input-visitor.

The fix makes use of qemu_strtod_finite(). To avoid ugly casts,

8258292e18 monitor: Remove "x-oob", offer capability "oob" unconditionally
Out-of-band command execution was introduced in commit cf869d5317.
Unfortunately, we ran into a regression, and had to turn it into an
experimental option for 2.12 (commit be933ffc23).

  http://lists.gnu.org/archive/html/qemu-devel/2018-03/msg06231.html

The regression has since been fixed (commit 951702f39c "monitor: bind
dispatch bh to iohandler context").  A thorough re-review of OOB
commands led to a few more issues, which have also been addressed.

This patch partly reverts be933ffc23 (monitor: new parameter "x-oob"),
and makes QMP monitors again offer capability "oob" whenever they can
provide it, i.e. when the monitor's character device is capable of
running in an I/O thread.

Some trivial touch-up in the test code is required to make sure qmp-test
won't break.

6bd858b311 block: Update BlockDriverState.inherits_from on bdrv_drop_intermediate()
The previous patch fixed the inherits_from pointer after block-stream,
and this one does the same for block-commit.

When block-commit finishes and the 'top' node is not the topmost one
from the backing chain then all nodes above 'base' up to and including
'top' are removed from the chain.

The bdrv_drop_intermediate() call converts a chain like this one:

    base <- intermediate <- top <- active

into this one:

    base <- active

In a simple scenario each backing file from the first chain has the
inherits_from attribute pointing to its parent. This means that
reopening 'active' will recursively reopen all its children, whose
options can be changed in the process.

However after the 'block-commit' call base.inherits_from is NULL and
the chain is broken, so 'base' does not inherit from 'active' and will
not be reopened automatically:

   $ qemu-img create -f qcow2 hd0.qcow2 1M
   $ qemu-img create -f qcow2 -b hd0.qcow2 hd1.qcow2
   $ qemu-img create -f qcow2 -b hd1.qcow2 hd2.qcow2
   $ $QEMU -drive if=none,file=hd2.qcow2

   { 'execute': 'block-commit',
     'arguments': {
       'device': 'none0',
       'top': 'hd1.qcow2' } }

   { 'execute': 'human-monitor-command',
     'arguments': {
        'command-line':
          'qemu-io none0 "reopen -o backing.l2-cache-size=2M"' } }

   { "return": "Cannot change the option 'backing.l2-cache-size'\r\n"}

This patch updates base.inherits_from in this scenario, and adds a
test case.

0065c455f9 block: Update BlockDriverState.inherits_from on bdrv_set_backing_hd()
When a BlockDriverState's child is opened (be it a backing file, the
protocol layer, or any other) inherits_from is set to point to the
parent node. Children opened separately and then attached to a parent
don't have this pointer set.

bdrv_reopen_queue_child() uses this to determine whether a node's
children must also be reopened inheriting the options from the parent
or not. If inherits_from points to the parent then the child is
reopened and its options can be changed, like in this example:

   $ qemu-img create -f qcow2 hd0.qcow2 1M
   $ qemu-img create -f qcow2 hd1.qcow2 1M
   $ $QEMU -drive if=none,node-name=hd0,file=hd0.qcow2,\
                  backing.driver=qcow2,backing.file.filename=hd1.qcow2
   (qemu) qemu-io hd0 "reopen -o backing.l2-cache-size=2M"

If the child does not inherit from the parent then it does not get
reopened and its options cannot be changed:

   $ $QEMU -drive if=none,node-name=hd1,file=hd1.qcow2
           -drive if=none,node-name=hd0,file=hd0.qcow2,backing=hd1
   (qemu) qemu-io hd0 "reopen -o backing.l2-cache-size=2M"
   Cannot change the option 'backing.l2-cache-size'

If a disk image has a chain of backing files then all of them are also
connected through their inherits_from pointers (i.e. it's possible to
walk the chain in reverse order from base to top).

However this is broken if the intermediate nodes are removed using
e.g. block-stream because the inherits_from pointer from the base node
becomes NULL:

   $ qemu-img create -f qcow2 hd0.qcow2 1M
   $ qemu-img create -f qcow2 -b hd0.qcow2 hd1.qcow2
   $ qemu-img create -f qcow2 -b hd1.qcow2 hd2.qcow2
   $ $QEMU -drive if=none,file=hd2.qcow2
   (qemu) qemu-io none0 "reopen -o backing.l2-cache-size=2M"
   (qemu) block_stream none0 0 hd0.qcow2
   (qemu) qemu-io none0 "reopen -o backing.l2-cache-size=2M"
   Cannot change the option 'backing.l2-cache-size'

This patch updates the inherits_from pointer if the intermediate nodes
of a backing chain are removed using bdrv_set_backing_hd(), and adds a
test case for this scenario.

87ad860c62 nvme: fix out-of-bounds access to the CMB
Because the CMB BAR has a min_access_size of 2, if you read the last
byte it will try to memcpy *2* bytes from n->cmbuf, causing an off-by-one
error.  This is CVE-2018-16847.

Another way to fix this might be to register the CMB as a RAM memory
region, which would also be more efficient.  However, that might be a
change for big-endian machines; I didn't think this through and I don't
know how real hardware works.  Add a basic testcase for the CMB in case
somebody does this change later on.

3b94c343f9 iotests: Add new test 220 for max compressed cluster offset
If you have a capable file system (tmpfs is good, ext4 not so much;
run ./check with TEST_DIR pointing to a good location so as not
to skip the test), it's actually possible to create a qcow2 file
that expands to a sparse 512T image with just over 38M of content.
The test is not the world's fastest (qemu crawling through 256M
bits of refcount table to find the next cluster to allocate takes
several seconds, as does qemu-img check reporting millions of
leaked clusters); but it DOES catch the problem that the previous
patch just fixed where writing a compressed cluster to a full
image ended up overwriting the wrong cluster.

1f442da51e tests/tcg/multiarch: fix 32bit linux-test on 64bit host
Fix:

  TEST    linux-test on i386
  .../tests/tcg/multiarch/linux-test.c:201: readdir

readdir() calls getdents64() to have the list of the entries in a
directory, and getdents64() can return 64bit d_off values (with ext4,
for instance) that will not fit in the 32bit d_off field of the
readdir() dirent structure.

To avoid that, use readdir64() to use a 64bit d_off field too.

0259e96687 tests/bios-tables-test: add 64-bit PCI MMIO aperture round-up test on Q35
In commit 9fa99d2519 ("hw/pci-host: Fix x86 Host Bridges 64bit PCI
hole", 2017-11-16), we meant to expose such a 64-bit PCI MMIO aperture in
the ACPI DSDT that would be at least as large as the new "pci-hole64-size"
property (2GB on i440fx, 32GB on q35). The goal was to offer "enough"
64-bit MMIO aperture to the guest OS for hotplug purposes.

Previous patch fixed the issue that the aperture is extended relative to
a possibly incorrect base.  This may result in an aperture size that is
smaller than the intent of commit 9fa99d2519.

This patch adds a test to make sure it won't happen again.

In the test case being added:
- use 128 MB initial RAM size,
- ask for one DIMM hotplug slot,
- ask for 2 GB maximum RAM size,
- use a pci-testdev with a 64-bit BAR of 2 GB size.

Consequences:

(1) In pc_memory_init() [hw/i386/pc.c], the DIMM hotplug area size is
    initially set to 2048-128 = 1920 MB. (Maximum RAM size minus initial
    RAM size.)

(2) The DIMM area base is set to 4096 MB (because the initial RAM is only
    128 MB -- there is no initial "high RAM").

(3) Due to commit 085f8e88ba ("pc: count in 1Gb hugepage alignment when
    sizing hotplug-memory container", 2014-11-24), we add 1 GB for the one
    DIMM hotplug slot that was specified. This sets the DIMM area size to
    1920+1024 = 2944 MB.

(4) The reserved-memory-end address (exclusive) is set to 4096 + 2944 =
    7040 MB (DIMM area base plus DIMM area size).

(5) The reserved-memory-end address is rounded up to GB alignment,
    yielding 7 GB (7168 MB).

(6) Given the 2 GB BAR size of pci-testdev, SeaBIOS allocates said 64-bit
    BAR in 64-bit address space.

(7) Because reserved-memory-end is at 7 GB, it is unaligned for the 2 GB
    BAR. Therefore SeaBIOS allocates the BAR at 8 GB. QEMU then
    (correctly) assigns the root bridge aperture base this BAR address, to
    be exposed in \_SB.PCI0._CRS.

(8) The intent of commit 9fa99d2519 dictates that QEMU extend the
    aperture size to 32 GB, implying a 40 GB end address. However, QEMU
    performs the extension relative to reserved-memory-end (7 GB), not
    relative to the bridge aperture base that was correctly deduced from
    SeaBIOS's BAR programming (8 GB). Therefore we see 39 GB as the
    aperture end address in \_SB.PCI0._CRS:
