tpm: Add support for TPM device over I2C bus
Qemu already supports devices attached to ISA and sysbus. This drop adds
support for the I2C bus attached TPM devices. I2C model only supports
TPM2 protocol.
This commit includes changes for the common code.
- Added I2C emulation model. Logic was added in the model to temporarily
cache the data as I2C interface works per byte basis.
- New tpm type "tpm-tis-i2c" added for I2C support. The user has to
provide this string on command line.
Testing:
TPM I2C device module is tested using SWTPM (software based TPM
package). Qemu uses the rainier machine and is connected to swtpm over
the socket interface.
The command to start swtpm is as follows:
$ swtpm socket --tpmstate dir=/tmp/mytpm1 \
--ctrl type=unixio,path=/tmp/mytpm1/swtpm-sock \
--tpm2 --log level=100
The command to start qemu is as follows:
$ qemu-system-arm -M rainier-bmc -nographic \
-kernel ${IMAGEPATH}/fitImage-linux.bin \

tpm: Extend common APIs to support TPM TIS I2C
Qemu already supports devices attached to ISA and sysbus. This drop adds
support for the I2C bus attached TPM devices.
This commit includes changes for the common code.
- Added support for the new checksum registers which are required for
the I2C support. The checksum calculation is handled in the qemu
common code.
- Added wrapper function for read and write data so that I2C code can
call it without MMIO interface.
The TPM TIS I2C spec describes in the table in section "Interface Locality
Usage per Register" that the TPM_INT_ENABLE and TPM_INT_STATUS registers
must be writable for any locality even if the locality is not the active
locality. Therefore, remove the checks whether the writing locality is the
active locality for these registers.

According to QEMU's support policy, we stop supporting the previous
major release two years after the the new major release has been
published. So we can stop testing FreeBSD 12 now and should switch
our FreeBSD VM to version 13 instead.
Some changes are needed for this update: The downloadable .ISO images
do not use the serial port as console by default anymore, so they
are not usable in the same way as with FreeBSD 12. Fortunately, the
FreeBSD project now also offers some pre-installed CI images that
have the serial console enabled, so we can use those now, with the
benefit that we can skip almost all parts of the previous installation
process.

hw/net/imx_fec: Support two Ethernet interfaces connected to single MDIO bus
The SOC on i.MX6UL and i.MX7 has 2 Ethernet interfaces. The PHY on each may
be connected to separate MDIO busses, or both may be connected on the same
MDIO bus using different PHY addresses. Commit
461c51ad4275 ("Add a phy-num
property to the i.MX FEC emulator") added support for specifying PHY
addresses, but it did not provide support for linking the second PHY on
a given MDIO bus to the other Ethernet interface.
To be able to support two PHY instances on a single MDIO bus, two properties
are needed: First, there needs to be a flag indicating if the MDIO bus on
a given Ethernet interface is connected. If not, attempts to read from this
bus must always return 0xffff. Implement this property as phy-connected.
Second, if the MDIO bus on an interface is active, it needs a link to the
consumer interface to be able to provide PHY access for it. Implement this
property as phy-consumer.

configure: Honour cross-prefix when finding ObjC compiler
Currently when configure picks an ObjectiveC compiler it doesn't pay
attention to the cross-prefix. This isn't a big deal in practice,
because we only use ObjC on macos and you can't cross-compile to
macos. But it's a bit inconsistent.
Rearrange the handling of objcc in configure so that we do the
same thing that we do with cc and cxx. This means that the logic
for picking the ObjC compiler goes from:
if --objcc is specified, use that
otherwise if clang is available, use that
otherwise use $cc
to:
if --objcc is specified, use that
otherwise if --cross-prefix is specified, use ${cross_prefix}clang
otherwise if clang is available, use that
otherwise use $cc

include an initialization 'int error_code = foo;' then the
initialization wouldn't actually happen (being dead code)
* it's against our coding style, which wants declarations to be

configure: Avoid -Werror=maybe-uninitialized
The configure script used to compile some code which dereferences memory
with ubsan to verify the compiler can link with ubsan library which
detects dereferencing of uninitialized memory. However, as the
dereferenced memory was allocated in the same code, GCC can statically
detect the unitialized memory dereference and emit maybe-uninitialized
warning. If -Werror is set, this becomes an error, and the configure
script incorrectly thinks the error indicates the compiler cannot use
ubsan.
Fix this error by replacing the code with another function which adds
1 to a signed integer argument. This brings in ubsan to detect if it
causes signed integer overflow. As the value of the argument cannot be
statically determined, the new function is also immune to compiler
warnings.

the input file if you're using the QMP interface -- there is no

Add command line syntax to allow specifying an input file
as well as an output file, using a new 'input-path' suboption.
The specific use case I have is that I'd like to be able to
feed fuzzer reproducer input into qtest without having to use
'-qtest stdio' and put the input onto stdin. Being able to
use a file chardev like this:
-chardev file,id=repro,path=/dev/null,input-path=repro.txt -qtest chardev:repro

Coverity spotted a double-free (CID

We should just use g_autoptr() for it anyway, which simplifies the code

migration/ram.c: Fix migration with compress enabled
Since
ec6f3ab9, migration with compress enabled was broken, because
the compress threads use a dummy QEMUFile which just acts as a
buffer and that commit accidentally changed it to use the outgoing
migration channel instead.
Fix this by using the dummy file again in the compress threads.

migration: Recover behavior of preempt channel creation for pre-7.2
In 8.0 devel window we reworked preempt channel creation, so that there'll
be no race condition when the migration channel and preempt channel got
established in the wrong order in commit
5655aab079.
However no one noticed that the change will also be not compatible with
older qemus, majorly 7.1/7.2 versions where preempt mode started to be
supported.
Leverage the same pre-7.2 flag introduced in the previous patch to recover
the behavior hopefully before 8.0 releases, so we don't break migration
when we migrate from 8.0 to older qemu binaries.

migration: Fix potential race on postcopy_qemufile_src
postcopy_qemufile_src object should be owned by one thread, either the main
thread (e.g. when at the beginning, or at the end of migration), or by the
return path thread (when during a preempt enabled postcopy migration). If
that's not the case the access to the object might be racy.
postcopy_preempt_shutdown_file() can be potentially racy, because it's
called at the end phase of migration on the main thread, however during
which the return path thread hasn't yet been recycled; the recycle happens
in await_return_path_close_on_source() which is after this point.
It means, logically it's posslbe the main thread and the return path thread
are both operating on the same qemufile. While I don't think qemufile is
thread safe at all.
postcopy_preempt_shutdown_file() used to be needed because that's where we
send EOS to dest so that dest can safely shutdown the preempt thread.
To avoid the possible race, remove this only place that a race can happen.
Instead we figure out another way to safely close the preempt thread on
dest.
The core idea during postcopy on deciding "when to stop" is that dest will
send a postcopy SHUT message to src, telling src that all data is there.
Hence to shut the dest preempt thread maybe better to do it directly on
dest node.
This patch proposed such a way that we change postcopy_prio_thread_created
into PreemptThreadStatus, so that we kick the preempt thread on dest qemu
by a sequence of:
mis->preempt_thread_status = PREEMPT_THREAD_QUIT;
qemu_file_shutdown(mis->postcopy_qemufile_dst);
While here shutdown() is probably so far the easiest way to kick preempt
thread from a blocked qemu_get_be64(). Then it reads preempt_thread_status
to make sure it's not a network failure but a willingness to quit the
thread.
We could have avoided that extra status but just rely on migration status.
The problem is postcopy_ram_incoming_cleanup() is just called early enough
so we're still during POSTCOPY_ACTIVE no matter what.. So just make it
simple to have the status introduced.
One flag x-preempt-pre-7-2 is added to keep old pre-7.2 behaviors of
postcopy preempt.

block, block-backend: write some hot coroutine wrappers by hand
The introduction of the graph lock is causing blk_get_geometry, a hot function
used in the I/O path, to create a coroutine. However, the only part that really
needs to run in coroutine context is the call to bdrv_co_refresh_total_sectors,
which in turn only happens in the rare case of host CD-ROM devices.
So, write by hand the three wrappers on the path from blk_co_get_geometry to
bdrv_co_refresh_total_sectors, so that the coroutine wrapper is only created
if bdrv_nb_sectors actually calls bdrv_refresh_total_sectors.

Not using blk_co_is_available() aligns the function with
