Richard Henderson bac8d222a1 configure: Add -Wno-psabi
On aarch64, gcc 9.3 is generating

qemu/exec.c: In function ‘address_space_translate_iommu’:
qemu/exec.c:431:28: note: parameter passing for argument of type \
  ‘MemTxAttrs’ {aka ‘struct MemTxAttrs’} changed in GCC 9.1

and many other repetitions.  This structure, and the functions
amongst which it is passed, are not part of a QEMU public API.
Therefore we do not care how the compiler passes the argument,
so long as the compiler is self-consistent.

The only portion of QEMU which does have a public api, and so
must have a stable abi, is "qemu/plugin.h".  We test this by
forcing -Wpsabi in tests/plugin/Makefile.

Eric Blake 3419ec713f iotests: Add copyright line in qcow2.py
The file qcow2.py was originally contributed in 2012 by Kevin Wolf,
but was not given traditional boilerplate headers at the time.  The
missing license was just rectified (commit 16306a7b39) using the
project-default GPLv2+, but as Vladimir is not at Red Hat, he did not
add a Copyright line.  All earlier contributions have come from CC'd
authors, where all but Stefan used a Red Hat address at the time of
the contribution, and that copyright carries over to the split to
qcow2_format.py (d5262c7124).

Roman Kagan c56ee92fcb block: consolidate blocksize properties consistency checks
Several block device properties related to blocksize configuration must
be in certain relationship WRT each other: physical block must be no
smaller than logical block; min_io_size, opt_io_size, and
discard_granularity must be a multiple of a logical block.

To ensure these requirements are met, add corresponding consistency
checks to blkconf_blocksizes, adjusting its signature to communicate
possible error to the caller.  Also remove the now redundant consistency
checks from the specific devices.

Alex Bennée c81950a2f1 plugins: new lockstep plugin for debugging TCG changes
When we make changes to the TCG we sometimes cause regressions that
are deep into the execution cycle of the guest. Debugging this often
requires comparing large volumes of trace information to figure out
where behaviour has diverged.

The lockstep plugin utilises a shared socket so two QEMU's running
with the plugin will write their current execution position and wait
to receive the position of their partner process. When execution
diverges the plugins output where they were and the previous few
blocks before unloading themselves and letting execution continue.

Originally I planned for this to be most useful with -icount but it
turns out you can get divergence pretty quickly due to asynchronous
qemu_cpu_kick_rr_cpus() events causing one side to eventually run into
a short block a few cycles before the other side. For this reason I've
added a bit of tracking and I think the divergence reporting could be
finessed to report only if we really start to diverge in execution.

An example run would be:

  qemu-system-sparc -monitor none -parallel none -net none \
    -M SS-20 -m 256 -kernel day11/zImage.elf \
    -plugin ./tests/plugin/liblockstep.so,arg=lockstep-sparc.sock \
    -d plugin,nochain

with an identical command in another window in the same working
directory.

Joseph Myers bc921b2711 target/i386: correct fix for pcmpxstrx substring search
This corrects a bug introduced in my previous fix for SSE4.2 pcmpestri
/ pcmpestrm / pcmpistri / pcmpistrm substring search, commit
ae35eea7e4.

That commit fixed a bug that showed up in four GCC tests with one libc
implementation.  The tests in question generate random inputs to the
intrinsics and compare results to a C implementation, but they only
test 1024 possible random inputs, and when the tests use the cases of
those instructions that work with word rather than byte inputs, it's
easy to have problematic cases that show up much less frequently than
that.  Thus, testing with a different libc implementation, and so a
different random number generator, showed up a problem with the
previous patch.

When investigating the previous test failures, I found the description
of these instructions in the Intel manuals (starting from computing a
16x16 or 8x8 set of comparison results) confusing and hard to match up
with the more optimized implementation in QEMU, and referred to AMD
manuals which described the instructions in a different way.  Those
AMD descriptions are very explicit that the whole of the string being
searched for must be found in the other operand, not running off the
end of that operand; they say "If the prototype and the SUT are equal
in length, the two strings must be identical for the comparison to be
TRUE.".  However, that statement is incorrect.

In my previous commit message, I noted:

  The operation in this case is a search for a string (argument d to
  the helper) in another string (argument s to the helper); if a copy
  of d at a particular position would run off the end of s, the
  resulting output bit should be 0 whether or not the strings match in
  the region where they overlap, but the QEMU implementation was
  wrongly comparing only up to the point where s ends and counting it
  as a match if an initial segment of d matched a terminal segment of
  s.  Here, "run off the end of s" means that some byte of d would
  overlap some byte outside of s; thus, if d has zero length, it is
  considered to match everywhere, including after the end of s.

The description "some byte of d would overlap some byte outside of s"
is accurate only when understood to refer to overlapping some byte
*within the 16-byte operand* but at or after the zero terminator; it
is valid to run over the end of s if the end of s is the end of the
16-byte operand.  So the fix in the previous patch for the case of d
being empty was correct, but the other part of that patch was not
correct (as it never allowed partial matches even at the end of the
16-byte operand).  Nor was the code before the previous patch correct
for the case of d nonempty, as it would always have allowed partial
matches at the end of s.

Fix with a partial revert of my previous change, combined with
inserting a check for the special case of s having maximum length to
determine where it is necessary to check for matches.

In the added test, test 1 is for the case of empty strings, which
failed before my 2017 patch, test 2 is for the bug introduced by my
2017 patch and test 3 deals with the case where a match of an initial
segment at the end of the string is not valid when the string ends
before the end of the 16-byte operand (that is, the case that would be
broken by a simple revert of the non-empty-string part of my 2017
patch).

Eric Blake 5c4fe018c0 nbd/server: Avoid long error message assertions CVE-2020-10761
Ever since commit 36683283 (v2.8), the server code asserts that error
strings sent to the client are well-formed per the protocol by not
exceeding the maximum string length of 4096.  At the time the server
first started sending error messages, the assertion could not be
triggered, because messages were completely under our control.
However, over the years, we have added latent scenarios where a client
could trigger the server to attempt an error message that would
include the client's information if it passed other checks first:

- requesting NBD_OPT_INFO/GO on an export name that is not present
  (commit 0cfae925 in v2.12 echoes the name)

- requesting NBD_OPT_LIST/SET_META_CONTEXT on an export name that is
  not present (commit e7b1948d in v2.12 echoes the name)

At the time, those were still safe because we flagged names larger
than 256 bytes with a different message; but that changed in commit
93676c88 (v4.2) when we raised the name limit to 4096 to match the NBD
string limit.  (That commit also failed to change the magic number
4096 in nbd_negotiate_send_rep_err to the just-introduced named
constant.)  So with that commit, long client names appended to server
text can now trigger the assertion, and thus be used as a denial of
service attack against a server.  As a mitigating factor, if the
server requires TLS, the client cannot trigger the problematic paths
unless it first supplies TLS credentials, and such trusted clients are
less likely to try to intentionally crash the server.

We may later want to further sanitize the user-supplied strings we
place into our error messages, such as scrubbing out control
characters, but that is less important to the CVE fix, so it can be a
later patch to the new nbd_sanitize_name.

Consideration was given to changing the assertion in
nbd_negotiate_send_rep_verr to instead merely log a server error and
truncate the message, to avoid leaving a latent path that could
trigger a future CVE DoS on any new error message.  However, this
merely complicates the code for something that is already (correctly)
flagging coding errors, and now that we are aware of the long message
pitfall, we are less likely to introduce such errors in the future,
which would make such error handling dead code.

Joseph Myers 975af797f1 target/i386: fix IEEE x87 floating-point exception raising
Most x87 instruction implementations fail to raise the expected IEEE
floating-point exceptions because they do nothing to convert the
exception state from the softfloat machinery into the exception flags
in the x87 status word.  There is special-case handling of division to
raise the divide-by-zero exception, but that handling is itself buggy:
it raises the exception in inappropriate cases (inf / 0 and nan / 0,
which should not raise any exceptions, and 0 / 0, which should raise
"invalid" instead).

Fix this by converting the floating-point exceptions raised during an
operation by the softfloat machinery into exceptions in the x87 status
word (passing through the existing fpu_set_exception function for
handling related to trapping exceptions).  There are special cases
where some functions convert to integer internally but exceptions from
that conversion are not always correct exceptions for the instruction
to raise.

There might be scope for some simplification if the softfloat
exception state either could always be assumed to be in sync with the
state in the status word, or could always be ignored at the start of
each instruction and just set to 0 then; I haven't looked into that in
detail, and it might run into interactions with the various ways the
emulation does not yet handle trapping exceptions properly.  I think
the approach taken here, of saving the softfloat state, setting
exceptions there to 0 and then merging the old exceptions back in
after carrying out the operation, is conservatively safe.

Joseph Myers c8af85b10c target/i386: fix fisttpl, fisttpll handling of out-of-range values
The fist / fistt family of instructions should all store the most
negative integer in the destination format when the rounded /
truncated integer result is out of range or the input is an invalid
encoding, infinity or NaN.  The fisttpl and fisttpll implementations
(32-bit and 64-bit results, truncate towards zero) failed to do this,
producing the most positive integer in some cases instead.  Fix this
by copying the code used to handle this issue for fistpl and fistpll,
adjusted to use the _round_to_zero functions for the actual
conversion (but without any other changes to that code).

an out-of-range result (invalid conversions always result in INT64_MAX

considered as out-of-range by this code) and storing the packed BCD
indefinite encoding in that case.

operation.  floatx80_scalbn ends up rounding the result using the

implementation to save and restore the rounding precision around the
call to floatx80_scalbn.

Joseph Myers c1c5fb8f90 target/i386: fix fscale handling of infinite exponents
The fscale implementation passes infinite exponents through to generic
code that rounds the exponent to a 32-bit integer before using
floatx80_scalbn.  In round-to-nearest mode, and ignoring exceptions,
this works in many cases.  But it fails to handle the special cases of
scaling 0 by a +Inf exponent or an infinity by a -Inf exponent, which
should produce a NaN, and because it produces an inexact result for
finite nonzero numbers being scaled, the result is sometimes incorrect
in other rounding modes.  Add appropriate handling of infinite
exponents to produce a NaN or an appropriately signed exact zero or
infinity as a result.

Vladimir Sementsov-Ogievskiy 93d487807b iotests: 194: wait for migration completion on target too
It is possible, that shutdown on target occurs earlier than migration
finish. In this case we crash in bdrv_release_dirty_bitmap_locked()
on assertion "assert(!bdrv_dirty_bitmap_busy(bitmap));" as we do have
busy bitmap, as bitmap migration is ongoing.

We'll fix bitmap migration to gracefully cancel on early shutdown soon.
Now let's fix iotest 194 to wait migration completion before shutdown.

Note that in this test dest_vm.shutdown() is called implicitly, as vms
used as context-providers, see __exit__() method of QEMUMachine class.

Actually, not waiting migration finish is a wrong thing, but the test
started to crash after commit ae00aa2398
"iotests: 194: test also migration of dirty bitmap", which added dirty
bitmaps here. So, Fixes: tag won't hurt.

nothing. Keep further refactoring of variable-length fields for another
day.

Vladimir Sementsov-Ogievskiy 5432a0db52 qcow2_format.py: use strings to specify c-type of struct fields
We are going to move field-parsing to super-class, this will be simpler
with simple string specifiers instead of variables.

For some reason, python doesn't allow the definition of ctypes variable
in the class alongside fields: it would not be available then for use
by the 'for' operator. Don't worry: ctypes will be moved to metaclass
soon.

Eric Auger c7504b9f32 tests: tpm-emu: Remove assert on TPM2_ST_NO_SESSIONS
bios-tables-test executes SeaBIOS. Indeed FW is needed to
fetch tables from QEMU and put them into the guest RAM. Also
the FW patches cross table pointers. At some point, SeaBIOS
ends up calling the TPM2_CC_HierarchyControl command with
TPM2_ST_SESSIONS tag, most probably steming from
tpm_set_failure/tpm20_hierarchycontrol SeaBIOS call path.
This causes an assert() in the qtest tpm emulation code.

As the goal here is not to boot SeaBIOS completely but just
let it grab the ACPI tables and consolidate them, let's just
remove the assert().

Because this is expected to be a transient condition, do not

Philippe Mathieu-Daudé 37914f603f tests/Makefile: Restrict some softmmu-only tests
In the next commit we are going to remove some objects from the
util-obj-y variable (objects which are not used by user-mode,
when configured with --disable-system).
Then some system-mode tests are going to fail, due to the missing
objects:

Instead, restrict these tests to system-mode, by using the

Thomas Huth 27dfbafaa7 tests/acceptance: Add a boot test for the xlnx-versal-virt machine
As described by Edgar here:

 https://www.mail-archive.com/qemu-devel@nongnu.org/msg605124.html

we can use the Ubuntu kernel for testing the xlnx-versal-virt machine.
So let's add a boot test for this now.

Alexander Bulekov dfd5ddb568 fuzz: run the main-loop in fork-server process
Without this, the time since the last main-loop keeps increasing, as the
fuzzer runs. The forked children need to handle all the "past-due"
timers, slowing them down, over time. With this change, the
parent/fork-server process runs the main-loop, while waiting on the
child, ensuring that the timer events do not pile up, over time.

Alexander Bulekov 3b113229c5 fuzz: add mangled object name to linker script
Previously, we relied on "FuzzerTracePC*(.bss*)" to place libfuzzer's
fuzzer::TPC object into our contiguous shared-memory region. This does
not work for some libfuzzer builds, so this addition identifies the
region by its mangled name: *(.bss._ZN6fuzzer3TPCE);
