hw/rdma: Skip data-path mr_id translation
With the change made in commit
68b89aee71 ("Utilize ibv_reg_mr_iova for
memory registration") the MR emulation is no longer needed in order to
translate the guest addresses into host addresses.
With that, the next obvious step is to skip entirely the processing in
data-path.
To accomplish this, return the backend's lkey to driver so we will not
need to do the emulated mr_id to backend mr_id translation in data-path.
The function build_host_sge_array is still called in data-path but only
for backward computability with statistics collection.
While there, as a cosmetic change to make the code cleaner - make one
copy of the function rdma_backend_create_mr and leave the redundant
guest_start argument in the legacy code.

hw/rdma: Cosmetic change - no need for two sge arrays
The function build_host_sge_array uses two sge arrays, one for input and
one for output.
Since the size of the two arrays is the same, the function can write
directly to the given source array (i.e. input/output argument).

linux-user/syscall: Add support for clock_gettime64/clock_settime64
Add support for the clock_gettime64/clock_settime64 syscalls.
If your host is 64-bit or is 32-bit with the *_time64 syscall then the
timespec will correctly be a 64-bit time_t. Otherwise the host will
return a 32-bit time_t which will be rounded to 64-bits. This will be
incorrect after y2038.

New y2038 safe 32-bit architectures (like RISC-V) don't support old
syscalls with a 32-bit time_t. The kernel defines new *_time64 versions
of these syscalls. Add some more #ifdefs to syscall.c in linux-user to

Firstly, _next_dirty_area is for scenarios when we may contiguously
search for next dirty area inside some limited region, so it is more
comfortable to specify "end" which should not be recalculated on each
iteration.
Secondly, let's add a possibility to limit resulting area size, not
limiting searching area. This will be used in NBD code in further
commit. (Note that now bdrv_dirty_bitmap_next_dirty_area is unused)

Therefore we can't handle bitmaps with absolute size larger than

cpu: Use DeviceClass reset instead of a special CPUClass reset
The CPUClass has a 'reset' method. This is a legacy from when
TYPE_CPU used not to inherit from TYPE_DEVICE. We don't need it any
more, as we can simply use the TYPE_DEVICE reset. The 'cpu_reset()'
function is kept as the API which most places use to reset a CPU; it
is now a wrapper which calls device_cold_reset() and then the
tracepoint function.
This change should not cause CPU objects to be reset more often
than they are at the moment, because:
* nobody is directly calling device_cold_reset() or
qdev_reset_all() on CPU objects
* no CPU object is on a qbus, so they will not be reset either
by somebody calling qbus_reset_all()/bus_cold_reset(), or
by the main "reset sysbus and everything in the qbus tree"
reset that most devices are reset by
Note that this does not change the need for each machine or whatever
to use qemu_register_reset() to arrange to call cpu_reset() -- that
is necessary because CPU objects are not on any qbus, so they don't
get reset when the qbus tree rooted at the sysbus bus is reset, and
this isn't being changed here.
All the changes to the files under target/ were made using the
included Coccinelle script, except:
(1) the deletion of the now-inaccurate and not terribly useful
"CPUClass::reset" comments was done with a perl one-liner afterwards:
perl -n -i -e '/ CPUClass::reset/ or print' target/*/*.c
(2) this bit of the s390 change was done by hand, because the
Coccinelle script is not sophisticated enough to handle the
parent_reset call being inside another function:

tests/docker: make "buildah bud" output similar to "docker build"
Podman users will most often be using buildah to build containers.
Among the differences between "buildah bud|build-using-dockerfile" and
a traditional "docker build" is that buildah does not run a container
during build.
To the best of my knowledge and experiments, this means that runtime
variables, such as ENV from one base image will not propagate into
another. The end result is that the location for the cross compiler
binaries, defined in the base "qemu/debian9-mxe" image, are not passed
through this image. Consequently, the cross compilers are not on PATH
and the build fails.

Acceptance test: add "boot_linux" tests
This acceptance test, validates that a full blown Linux guest can
successfully boot in QEMU. In this specific case, the guest chosen is
Fedora version 31.
* x86_64, pc-i440fx and pc-q35 machine types, with TCG and KVM as
accelerators
* aarch64 and virt machine type, with TCG and KVM as accelerators
* ppc64 and pseries machine type with TCG as accelerator
* s390x and s390-ccw-virtio machine type with TCG as accelerator
The Avocado vmimage utils library is used to download and cache the
Linux guest images, and from those images a snapshot image is created
and given to QEMU. If a qemu-img binary is available in the build
directory, it's used to create the snapshot image, so that matching
qemu-system-* and qemu-img are used in the same test run. If qemu-img
is not available in the build tree, one is attempted to be found
installed system-wide (in the $PATH). If qemu-img is not found in the
build dir or in the $PATH, the test is canceled.
The method for checking the successful boot is based on "cloudinit"
and its "phone home" feature. The guest is given an ISO image with
the location of the phone home server, and the information to post
(the instance ID). Upon receiving the correct information, from the
guest, the test is considered to have PASSed.
This test is currently limited to user mode networking only, and
instructs the guest to connect to the "router" address that is hard
coded in QEMU.
To create the cloudinit ISO image that will be used to configure the
guest, the pycdlib library is also required and has been added as
requirement to the virtual environment created by "check-venv".
The console output is read by a separate thread, by means of the
Avocado datadrainer utility module.

This introduces three variables that can help tests find resources in

First, a BUILD_DIR is assumed to exist, given that the primary form of
running the acceptance tests is from a build directory (which may or

If the directory containing the acceptance tests happens to be a link

net: Complete qapi-fication of netdev_add
We've had all the required pieces for doing a type-safe representation
of netdev_add as a flat union for quite some time now (since
0e55c381f6 in v2.7.0, released in 2016), but did not make the final
switch to using it because of concern about whether a command-line
regression in accepting "1" in place of 1 for integer arguments would
be problematic. Back then, we did not have the deprecation cycle to
allow us to make progress. But now that we have waited so long, other
problems have crept in: for example, our desire to add
qemu-storage-daemon is hampered by the inability to express net
objects, and we are unable to introspect what we actually accept.
Additionally, our round-trip through QemuOpts silently eats any
argument that expands to an array, rendering dnssearch, hostfwd, and
guestfwd useless through QMP:
{"execute": "netdev_add", "arguments": { "id": "netdev0",
"type": "user", "dnssearch": [
{ "str": "8.8.8.8" }, { "str": "8.8.4.4" }
]}}
So without further ado, let's turn on proper QAPI. netdev_add() was a
trivial wrapper around net_client_init(), which did a few steps prior
to calling net_client_init1(); with this patch, we now skip directly
to net_client_init1(). In addition to fixing array parameters, the
following additional differences occur:
- {"execute": "netdev_add", "arguments": {"type": "help"}}
no longer attempts to print help to stdout and exit. Bug fix, broken
in
547203ead4 'net: List available netdevs with "-netdev help"',
v2.12.0.
- {"execute": "netdev_add", "arguments': {... "ipv6-net": "..." }}
no longer attempts to desugar the undocumented ipv6-net magic string
into the proper "ipv6-prefix" and "ipv6-prefixlen". Undocumented
misfeature, introduced in commit
7aac531ef2 "qapi-schema, qemu-options
& slirp: Adding Qemu options for IPv6 addresses", v2.6.0.
- {'execute':'netdev_add',
'arguments':{'id':'net2', 'type':'hubport', 'hubid':"2"}}
{"error": {"class": "GenericError", "desc": "Invalid parameter type for 'hubid', expected: integer"}}
Used to succeed: since our command line treats everything as strings,
our not-so-round-trip conversion from QAPI -> QemuOpts -> QAPI lost
the original typing and turned everything into a string; now that we
skip the QemuOpts, the JSON input has to match the exact QAPI type.
But this stricter QMP is desirable, and introspection is sufficient
for any affected applications to make sure they use it correctly.
In qmp_netdev_add(), we still have to create a QemuOpts object so that
qmp_netdev_del() will be able to remove a hotplugged network device;
but the opts->head remains empty since we now manage all parsing
through the QAPI object rather than QemuOpts; a separate patch will
address the abuse of QemuOpts as a witness for whether a
NetClientState is a netdev. In the meantime, our argument that we are
okay requires auditing all uses of option group "netdev":
- qemu_netdev_opts: option group definition, empty .desc[]
- CLI (CLI netdev parsing ends before monitors start, so while
monitors can mess with CLI netdevs, CLI cannot mess with
monitor netdevs):
- main() case QEMU_OPTION_netdev: store CLI definition
- main() case QEMU_OPTION_readconfig, case QEMU_OPTION_writeconfig:
similar, dealing only with CLI
- net_init_clients(): Pass CLI to net_client_init()
- Monitor:
- hmp_netdev_add(): straightforward parse into net_client_init()
- qmp_netdev_add(): subject of this patch, used to add full
object to option group, now just adds bare-bones id
- qmp_netdev_del(), netdev_del_completion(): check the option group
solely for id, as a 'is this a netdev' predicate
