The vmstate save/load code insists that subsections of a VMState must
have names which include their parent VMState's name as a leading
substring. Unfortunately it neither documents this nor checks it on
device init or state save, but instead fails state load with a
confusing error message ("Missing section footer for armv7m_nvic").
Fix the name of the m-security subsection of the NVIC, so that
state save/load works correctly for the security-enabled NVIC.

When copy_properties_from_host() ignores the error for an optional
property, it frees the error, but fails to reset it.
Hence if two or more optional properties are missing, an assertion is
triggered:
util/error.c:57: error_setv: Assertion `*errp == NULL' failed.
Fis this by resetting err to NULL after ignoring the error.

The BLKDISCARD ioctl doesn't guarantee that the discarded blocks read as
all-zero afterwards, so don't try to abuse it for zero writing. We try
to only use this if BLKDISCARDZEROES tells us that it is safe, but this
is unreliable on older kernels and a constant 0 in newer kernels. In
other words, this code path is never actually used with newer kernels,
so we don't even try to unmap while writing zeros.
This patch removes the abuse of discard for writing zeroes from
file-posix and instead adds a new function that uses interfaces that are
actually meant to deallocate and zero out at the same time. Only if
those fail, it falls back to zeroing out without unmap. We never fall
back to a discard operation any more that may or may not result in
zeros.

qstring_from_substr() parameters @start and @end are of type int.
blkdebug_parse_filename(), blkverify_parse_filename(), nbd_parse_uri(),

Values exceeding INT_MAX get truncated, with possibly disastrous

Such huge substrings seem unlikely, but we found one in a core dump,

When gnutls negotiates TLS 1.3 instead of 1.2, the order of messages
sent by the handshake changes. This exposed a logic bug in the test
suite which caused us to wait for the server to see handshake
completion, but not wait for the client to see completion. The result
was the client didn't receive the certificate for verification and the
test failed.
This is exposed in Fedora 29 rawhide which has just enabled TLS 1.3 in
its GNUTLS builds.

Most of the TLS related tests are passing an in a "Error" object to
methods that are expected to fail, but then ignoring any error that is
set and instead asserting on a return value. This means that when an
error is unexpectedly raised, no information about it is printed out,
making failures hard to diagnose. Changing these tests to pass in
&error_abort will make unexpected failures print messages to stderr.

The test-vmstate test is a bit chatty because it triggers various

g_test_message() instead of stderr:

Unfortunately this change has global impact across the entire test suite
and means that when tests fail for unexpected reasons, the message is
not displayed on stderr. eg when using &error_abort in a call the test
merely prints
Unexpected error in qcrypto_tls_session_check_certificate() at crypto/tlssession.c:280:
and the actual error message is hidden, making it impossible to diagnose
the failure. This is especially problematic in CI or build systems where
it isn't possible to easily pass the --debug-log flag to tests and
re-run with the test log visible.
This change makes the previous big hammer much more nuanced, providing a
flag in the stub error_vprintf() that can used on a per-test basis to
silence the errors. Only the test-vmstate silences errors initially.

The only possible change of last_byte is when it reaches the edge.
Setting it every time might let last_byte contain an invalid data when
memory corruption is detected, then the check of the next byte will be
incorrect. For example, a single page corruption at address 0x14ad000
will also lead to a "fake" corruption at 0x14ae000:
Memory content inconsistency at 14ad000 first_byte = 44 last_byte = 44 current = ef hit_edge = 0
Memory content inconsistency at 14ae000 first_byte = 44 last_byte = ef current = 44 hit_edge = 0
After the patch, it'll only report the corrputed page:
Memory content inconsistency at 14ad000 first_byte = 44 last_byte = 44 current = ef hit_edge = 0
