Coverity is reporting in CID 1405304 that tpm_execute() may pass a NULL

pseries: do not allow memory-less/cpu-less NUMA node
When we hotplug a CPU on memory-less/cpu-less node, the linux kernel
crashes.
This happens because linux kernel needs to know the NUMA topology at
start to be able to initialize the distance lookup table.
On pseries, the topology is provided by the firmware via the existing
CPUs and memory information. Thus a node without memory and CPU cannot be
discovered by the kernel.
To avoid the kernel crash, do not allow to start pseries with empty
nodes.

of one specific accelerator.
In the long run, we really should rework the "-accel" code completely,
so that it does not set "-machine accel=..." anymore internally, but
is completely independent from "-machine". For the short run, let's
make sure that users cannot use "-accel xyz:tcg", so that we avoid

hw/core/loader: Fix possible crash in rom_copy()
Both, "rom->addr" and "addr" are derived from the binary image
that can be loaded with the "-kernel" paramer. The code in
rom_copy() then calculates:
d = dest + (rom->addr - addr);
and uses "d" as destination in a memcpy() some lines later. Now with
bad kernel images, it is possible that rom->addr is smaller than addr,
thus "rom->addr - addr" gets negative and the memcpy() then tries to
copy contents from the image to a bad memory location. This could
maybe be used to inject code from a kernel image into the QEMU binary,
so we better fix it with an additional sanity check here.

of the control register of the RTC, which is currently not implemented yet.
Thus, let's add a register variable for this now. However, the RTC
registers are currently defined as static variables in nextscr2_write(),
which is quite ugly. Thus let's also move the RTC variables to the main
machine state instead. In the long run, we should likely even refactor
the whole RTC code into a separate device in a separate file, but that's
something for calm winter nights later... as a first step, cleaning up

s390: do not call memory_region_allocate_system_memory() multiple times
s390 was trying to solve limited KVM memslot size issue by abusing
memory_region_allocate_system_memory(), which breaks API contract
where the function might be called only once.
Beside an invalid use of API, the approach also introduced migration
issue, since RAM chunks for each KVM_SLOT_MAX_BYTES are transferred in
migration stream as separate RAMBlocks.
After discussion [1], it was agreed to break migration from older
QEMU for guest with RAM >8Tb (as it was relatively new (since 2.12)
and considered to be not actually used downstream).
Migration should keep working for guests with less than 8TB and for
more than 8TB with QEMU 4.2 and newer binary.
In case user tries to migrate more than 8TB guest, between incompatible
QEMU versions, migration should fail gracefully due to non-exiting
RAMBlock ID or RAMBlock size mismatch.

big MemorySection into several memslots, partially revert commit

Have check_exprs() call check_keys() later, so its error messages gain

Both check_keys() and check_name_is_str() check the definition's name
is a string. Since check_keys() now runs after check_name_is_str()
rather than before, its check is dead. Bury it. Checking values in
check_keys() is unclean anyway.
Split check_flags() off check_keys() and have check_exprs() call it
later, so its error messages gain an "in definition" line. Tweak the
error messages.
Checking values in a function named check_keys() is unclean anyway.
Move check_if() from check_keys() to check_exprs() and call it later,
so its error messages gain an "in definition" line.
Checking values in a function named check_keys() is unclean anyway.
The original sin was commit 0545f6b887 "qapi: Better error messages
for bad expressions", which checks the value of key 'name'. More
sinning in commit 2cbf09925a "qapi: More rigorous checking for type
safety bypass", commit c818408e44 "qapi: Implement boxed types for
commands/events", and commit 967c885108 "qapi: add 'if' to top-level
expressions". This commit does penance for the latter. The next
commits will do penance for the others.
qapi: Move context-free checking to the proper place
QAPISchemaCommand.check() and QAPISchemaEvent().check() check 'data'
is present when 'boxed': true. That's context-free. Move to
check_command() and check_event().
Tweak the error message while there.
check_exprs() & friends now check exactly what qapi-code-gen.txt calls
the second layer of syntax.
qapi: Move context-sensitive checking to the proper place
When we introduced the QAPISchema intermediate representation (commit ac88219a6c7), we took a shortcut: we left check_exprs() & friends
alone instead of moving semantic checks into the
QAPISchemaFOO.check(). The .check() assert check_exprs() did its job.
Time to finish the conversion job. Move exactly the context-sensitive
checks to the .check(). They replace assertions there. Context-free
checks stay put.
Fixes the misleading optional tag error demonstrated by test
flat-union-optional-discriminator.
check_name() consists of check_name_is_str() and check_name_str().
check_union() relies on the latter to catch optional discriminators.
The next commit will replace that by a more straightforward check.
Inlining check_name() into check_union() now should make that easier
to review.
qapi: Make check_type()'s array case a bit more obvious
check_type() checks the array's contents, then peels off the array and
falls through to the "not array" code without resetting allow_array
and allow_dict to False. Works because the peeled value is a string,
and allow_array and allow_dict aren't used then. Tidy up anyway:
recurse instead, defaulting allow_array and allow_dict to False.
qapi: Move check for reserved names out of add_name()
The checks for reserved names are spread far and wide. Move one from
add_name() to new check_defn_name_str(). This is a first step towards
collecting them all in dedicated name checking functions next to
check_name().
While there, drop the quotes around the meta-type in
check_name_str()'s error messages: "'command' uses ... name 'NAME'"
becomes "command uses ... name 'NAME'".
struct-base-clash.json: In struct 'Sub':
struct-base-clash.json:5: 'name' (member of Sub) collides with 'name' (member of Base)
The "(member of Sub)" is redundant with "In struct 'Sub'". Comes from
QAPISchemaMember.describe(). Pass info to it, so it can detect the
redundancy and avoid it. Result:
struct-base-clash.json: In struct 'Sub':
struct-base-clash.json:5: member 'name' collides with member 'name' of type 'Base'
qapi: Change frontend error messages to start with lower case
Starting error messages with a capital letter complicates things when
text can get interpolated both at the beginning and in the middle of
an error message. The next patch will do that. Switch to lower case
to keep it simpler.
For what it's worth, the GNU Coding Standards advise the message
"should not begin with a capital letter when it follows a program name
and/or file name, because that isn’t the beginning of a sentence. (The
sentence conceptually starts at the beginning of the line.)"
While there, avoid breaking lines containing multiple arguments in the
middle of an argument.
QAPISchemaMember.check_clash() checks for member names that map to the
same c_name(). Takes care of rejecting duplicate names.
It also checks a naming rule: no uppercase in member names. That's a
rather odd place to do it. Enforcing naming rules is
check_name_str()'s job.
qapi-code-gen.txt specifies the name case rule applies to the name as
it appears in the schema. check_clash() checks c_name(name) instead.
No difference, as c_name() leaves alone case, but unclean.
Move the name case check into check_name_str(), less the c_name().
New argument @permit_upper suppresses it. Pass permit_upper=True for
definitions (which are not members), and when the member's owner is
whitelisted with pragma name-case-whitelist.
Bonus: name-case-whitelist now applies to a union's inline base, too.
Update qapi/qapi-schema.json pragma to whitelist union CpuInfo instead
of CpuInfo's implicit base type's name q_obj_CpuInfo-base.
qapi: Prefix frontend errors with an "in definition" line
We take pains to include the offending expression in error messages,
e.g.
tests/qapi-schema/alternate-any.json:2: alternate 'Alt' member 'one' cannot use type 'any'
But not always:
tests/qapi-schema/enum-if-invalid.json:2: 'if' condition must be a string or a list of strings
Instead of improving them one by one, report the offending expression
whenever it is known, like this:
tests/qapi-schema/enum-if-invalid.json: In enum 'TestIfEnum':
tests/qapi-schema/enum-if-invalid.json:2: 'if' condition must be a string or a list of strings
Error messages that mention the offending expression become a bit
redundant, e.g.
tests/qapi-schema/alternate-any.json: In alternate 'Alt':
tests/qapi-schema/alternate-any.json:2: alternate 'Alt' member 'one' cannot use type 'any'
QAPISchemaMember.owner is the name of the defining entity. That's a
confusing name when an object type inherits members from a base type.
Rename it to .defined_in. Rename .set_owner() and ._pretty_owner() to
match.
When we introduced the QAPISchema intermediate representation (commit ac88219a6c7), we took a shortcut: we left check_exprs() & friends
alone instead of moving semantic checks into the
QAPISchemaFOO.check(). check_exprs() still checks and reports errors,
and the .check() assert check_exprs() did the job. There are a few
gaps, though.
QAPISchemaArrayType.check() neglects to assert the element type is not
an array. Add the assertion.
QAPISchemaObjectTypeVariants.check() neglects to assert the tag member
is not optional. Add the assertion.
It neglects to assert the tag member is not conditional. Add the
assertion.
It neglects to assert we actually have variants. Add the assertion.
It asserts the variants are object types, but neglects to assert they
don't have variants. Tighten the assertion.
QAPISchemaObjectTypeVariants.check_clash() has the same issue.
However, it can run only after .check(). Delete the assertion instead
of tightening it.
QAPISchemaAlternateType.check() neglects to assert the branch types
don't conflict. Fixing that isn't trivial, so add just a TODO comment
for now. It'll be resolved later in this series.

It used to not matter that we didn't do this until commit fc1120a7f5f2d4b6, where we implemented actually honouring
these NSACR bits.
The problem only exists for CPUs where EL3 is AArch32; the
equivalent AArch64 trap bits are in CPTR_EL3 and are "0 to
not trap, 1 to trap", so the reset value of the register
permits NS access, unlike NSACR.

can't build a modern QEMU with the image. Let's put the thing out of
its misery and remove it.
People who really care about building on powerpc can still use the
binfmt_misc support to manually build an image (or just run the build
from pre this commit).

docker: move tests from python2 to python3
As part of the push to drop python2 support, replace any explicit python2
dependencies with python3 versions.
For centos, python2 still exists as an implicit dependency, but by adding
python3 we will be able to build even if the configure script begins to
require python 3.5+.
Tested with centos7, fedora, ubuntu, ubuntu1804, and debian 9 (amd64).
Tested under a custom configure script that requires Python 3.5+.
the travis dockerfile is also moved to using python3, which was tested
by running `make docker-test-build@travis`, which I hope is sufficient.

debian-sid is listed as a partial image, so we cannot run tests against it.
Since it isn't used by any other testable image, remove it for now as it
is prone to bitrot.

debian8 partial base is also not consumed by any image, so remove it.

configure: preserve PKG_CONFIG for subdir builds
The slirp sub-module complains about not being able to find the glib
library on cross-compiles because it is using the default pkg-config
tool (which isn't installed in our cross-build docker images).
Preserve PKG_CONFIG in our host config and pass it down to slirp.

tests/tcg: add simple record/replay smoke test for aarch64
This adds two new tests that re-use the memory test to check basic
record replay functionality is still working. We have to define our
own runners rather than using the default pattern as we want to change
the test name but re-use the memory binary.
We declare the test binaries as PHONY as they don't really exist.
[AJB: A better test would output some sort of timer value or other
otherwise variable value so we could compare the record and replay
outputs and ensure they match]

tests/tcg: add generic version of float_convs
This is broadly similar to the existing fcvt test for ARM but using
the generic float testing framework. We should be able to pare down
the ARM fcvt test case to purely half-precision with or without the
Alt HP provision.

tests/tcg: add float_madds test to multiarch
This is a generic floating point multiply and accumulate test for
single precision floating point values. I've split of the common float
functions into a helper library so additional tests can use the same
common code.
As I don't have references for all architectures I've allowed some
flexibility for tests to pass without reference files. They can be
added as we get collect them.
