When the NVMe block driver was introduced (see commit bdd6a90a9e,
January 2018), Linux VFIO_IOMMU_MAP_DMA ioctl was only returning
-ENOMEM in case of error. The driver was correctly handling the
error path to recycle its volatile IOVA mappings.
To fix CVE-2019-3882, Linux commit 492855939bdb ("vfio/type1: Limit
DMA mappings per container", April 2019) added the -ENOSPC error to
signal the user exhausted the DMA mappings available for a container.
The block driver started to mis-behave:
qemu-system-x86_64: VFIO_MAP_DMA failed: No space left on device
(qemu)
(qemu) info status
VM status: paused (io-error)
(qemu) c
VFIO_MAP_DMA failed: No space left on device
(qemu) c
VFIO_MAP_DMA failed: No space left on device
(The VM is not resumable from here, hence stuck.)
Fix by handling the new -ENOSPC error (when DMA mappings are
exhausted) without any distinction to the current -ENOMEM error,
so we don't change the behavior on old kernels where the CVE-2019-3882
fix is not present.
An easy way to reproduce this bug is to restrict the DMA mapping
limit (65535 by default) when loading the VFIO IOMMU module:
# modprobe vfio_iommu_type1 dma_entry_limit=666

Since commit 8eb13bbbac ("ui/gtk: vte: fix sending multiple
characeters") it's very easy to lock up QEMU with the GTK ui.
If you configure a guest with a serial device and the guest
doesn't listen on this device, QEMU will lock up after
entering two characters in the serial console. That's because
current code uses a busy loop for the chardev write retries
and the busy loop doesn't terminate in this case.
To fix this problem add a fifo to the VTE consoles and use the
chr_accept_input() callback function to write the remaining
characters in the queue to the chardev.
The fifo has a size of 4096 bytes, so one can copy and paste
a fairly large URL or file path.

To handle relative mouse input the event handler needs to move the mouse
away from the screen edges. Failing to do so results in the mouse
getting stuck at invisible walls. However the current implementation for
this is broken on hosts with multiple monitors.
With multiple monitors the mouse can be located outside of the current
monitor which is not handled by the current code. Also the monitor
itself might be located at coordinates different from (0, 0).

All jobs depending on 'docker-opensbi' job must use at most all
the rules that triggers it. The simplest way to ensure that
is to always use the same rules. Extract all the rules to a
reusable section, and include this section (with the 'extends'
keyword) in both 'docker-opensbi' and 'build-opensbi' jobs.
The problem was introduced in commit c6fc0fc1a7 ("gitlab-ci.yml:
Add jobs to build OpenSBI firmware binaries"), but was revealed in
commit 91e9c47e50 ("docker: OpenSBI build job depends on OpenSBI
container").
This fix is similar to the one used with the EDK2 firmware job in
commit ac0595cf6b ("gitlab-ci: Extract EDK2 job rules to reusable
section").

Up until this point we only handled local compilers or assumed we had
everything in the container. This falls down when we are building QEMU
inside the container.
This special handling only affects tricore for now but I put it in a
case just in case we add any other "special" targets. Setting
CROSS_CC_GUEST is a bit of a hack just to ensure the test runs as we
gate on a detected compiler even though the Makefile won't actually
use it. It also means we display something sane in the configure

In user-mode emulation there is a small race between preexit_cleanup
and exit_group() which means we may end up calling instrumented
instructions before the kernel reaps child threads. To solve this we
implement a new helper which ensures the callbacks are flushed along
with any translations before we let the host do it's a thing.
While we are at it make the documentation of
qemu_plugin_register_atexit_cb clearer as to what the user can expect.

Alias targets have a different name than the alias property itself
(e.g. a machine's pflash0 might be an alias of a property named 'drive').
When the target's getter or setter invokes the visitor, it will use
a different name than what the caller expects, and the visitor will
not be able to find it (or will consume erroneously).
The solution is for alias getters and setters to wrap the incoming
visitor, and forward the sole field that the target is expecting while
renaming it appropriately.
This bug has been there forever, but it was exposed after -M parsing
switched from QemuOptions and StringInputVisitor to keyval and
QObjectInputVisitor. Before, the visitor ignored the name. Now, it
checks "drive" against what was passed on the command line and finds
that no such property exists.

GitLab will happily publish pages generated by the latest CI pipeline

https://docs.gitlab.com/ee/user/project/pages/introduction.html
"Remember that GitLab Pages are by default branch/tag agnostic
and their deployment relies solely on what you specify in
.gitlab-ci.yml. You can limit the pages job with the only
parameter, whenever a new commit is pushed to a branch used
specifically for your pages."
The current "pages" job is not limited, so it is happily publishing
docs content from any branch/tag in qemu.git that gets pushed to.
This means we're potentially publishing from the "staging" branch
or worse from outdated "stable-NNN" branches
This change restricts it to only publish from the default branch
in the main repository. For contributor forks, however, we allow
it to publish from any branch, since users will have arbitrarily
named topic branches in flight at any time.

Some cpu properties have to be set only for cpu models in builtin_x86_defs,
registered with x86_register_cpu_model_type, and not for
cpu models "base", "max", and the subclass "host".
These properties are the ones set by function x86_cpu_apply_props,
(also including kvm_default_props, tcg_default_props),
and the "vendor" property for the KVM and HVF accelerators.
After recent refactoring of cpu, which also affected these properties,
they were instead set unconditionally for all x86 cpus.
This has been detected as a bug with Nested on AMD with cpu "host",
as svm was not turned on by default, due to the wrongful setting of
kvm_default_props via x86_cpu_apply_props, which set svm to "off".
Rectify the bug introduced in commit "i386: split cpu accelerators"
and document the functions that are builtin_x86_defs-only.

All MBZ in CR3 must be zero (APM2 15.5)
Added checks in both helper_vmrun and helper_write_crN.
When EFER.LMA is zero the upper 32 bits needs to be zeroed.

modinfo runs the preprocessor and therefore needs all generated input files
to be there. The "depends" clause does not work in Meson 0.55.3, so for
now use "input".
Part #2: Update the rule for target-specific modules too.

Before commit 49afbca3b0 ("virtio-gpu: drop
use_virgl_renderer"), use_virgl_renderer was preventing calling GL
functions from non-GL context threads. The innocuously looking
g->parent_obj.use_virgl_renderer = false;
was set the first time virtio_gpu_gl_reset() was called, during
pc_machine_reset() in the main thread. Further virtio_gpu_gl_reset()
calls in IO threads, without associated GL context, were thus skipping
GL calls and avoided warnings or crashes (see also
https://gitlab.freedesktop.org/virgl/virglrenderer/-/issues/226).
