b5e0d5d22f target/i386: Fix 32-bit wrapping of pc/eip computation
In 32-bit mode, pc = eip + cs_base is also 32-bit, and must wrap.
Failure to do so results in incorrect memory exceptions to the guest.
Before 732d548732, this was implicitly done via truncation to
target_ulong but only in qemu-system-i386, not qemu-system-x86_64.

To fix this, we must add conditional zero-extensions.
Since we have to test for 32 vs 64-bit anyway, note that cs_base
is always zero in 64-bit mode.

06ecb6ac19 docs: clean-up the xenpvh documentation
I noticed the code blocks where not rendering properly so thought I'd
better fix things up. So:

  - Use better title for the machine type
  - Explain why Xen is a little different
  - Add a proper anchor to the tpm-device link
  - add newline so code block properly renders
  - add some indentation to make continuation clearer

755ae3811f block: Fix AioContext locking in qmp_block_resize()
The AioContext must be unlocked before calling blk_co_unref(), because
it takes the AioContext lock internally in blk_unref_bh(), which is
scheduled in the main thread. If we don't unlock, the AioContext is
locked twice and nested event loops such as in bdrv_graph_wrlock() will
deadlock.

16b6273b4b meson, xen: fix condition for enabling the Xen accelerator
A misspelled condition in xen_native.h is hiding a bug in the enablement of
Xen for qemu-system-aarch64.  The bug becomes apparent when building for
Xen 4.18.

While the i386 emulator provides the xenpv machine type for multiple architectures,
and therefore can be compiled with Xen enabled even when the host is Arm, the
opposite is not true: qemu-system-aarch64 can only be compiled with Xen support
enabled when the host is Arm.

Expand the computation of accelerator_targets['CONFIG_XEN'] similar to what is
already there for KVM.

5746f70d68 i386/sev: Avoid SEV-ES crash due to missing MSR_EFER_LMA bit
Commit 7191f24c7f ("accel/kvm/kvm-all: Handle register access errors")
added error checking for KVM_SET_SREGS/KVM_SET_SREGS2. In doing so, it
exposed a long-running bug in current KVM support for SEV-ES where the
kernel assumes that MSR_EFER_LMA will be set explicitly by the guest
kernel, in which case EFER write traps would result in KVM eventually
seeing MSR_EFER_LMA get set and recording it in such a way that it would
be subsequently visible when accessing it via KVM_GET_SREGS/etc.

However, guest kernels currently rely on MSR_EFER_LMA getting set
automatically when MSR_EFER_LME is set and paging is enabled via
CR0_PG_MASK. As a result, the EFER write traps don't actually expose the
MSR_EFER_LMA bit, even though it is set internally, and when QEMU
subsequently tries to pass this EFER value back to KVM via
KVM_SET_SREGS* it will fail various sanity checks and return -EINVAL,
which is now considered fatal due to the aforementioned QEMU commit.

This can be addressed by inferring the MSR_EFER_LMA bit being set when
paging is enabled and MSR_EFER_LME is set, and synthesizing it to ensure
the expected bits are all present in subsequent handling on the host
side.

Ultimately, this handling will be implemented in the host kernel, but to
avoid breaking QEMU's SEV-ES support when using older host kernels, the
same handling can be done in QEMU just after fetching the register
values via KVM_GET_SREGS*. Implement that here.

80a37b039e hw/ufs: avoid generating the same ID string for different LU devices
QEMU would not start when trying to create two UFS host controllers and
a UFS logical unit for each with the following options:

-device ufs,id=bus0 \
-device ufs-lu,drive=drive1,bus=bus0,lun=0 \
-device ufs,id=bus1 \
-device ufs-lu,drive=drive2,bus=bus1,lun=0 \

This is because the same ID string ("0:0:0/scsi-disk") is generated
for both UFS logical units.

To fix this issue, prepend the parent pci device's path to make
the ID string unique.
("0000:00:03.0/0:0:0/scsi-disk" and "0000:00:04.0/0:0:0/scsi-disk")

Resolves: #2018

560b8e1d70 target/riscv/kvm: fix shadowing in kvm_riscv_(get|put)_regs_csr
KVM_RISCV_GET_CSR() and KVM_RISCV_SET_CSR() use an 'int ret' variable
that is used to do an early 'return' if ret > 0. Both are being called
in functions that are also declaring a 'ret' integer, initialized with
'0', and this integer is used as return of the function.

The result is that the compiler is less than pleased and is pointing
shadowing errors:

../target/riscv/kvm/kvm-cpu.c: In function 'kvm_riscv_get_regs_csr':
../target/riscv/kvm/kvm-cpu.c:90:13: error: declaration of 'ret' shadows a previous local [-Werror=shadow=compatible-local]
   90 |         int ret = kvm_get_one_reg(cs, RISCV_CSR_REG(env, csr), &reg); \
      |             ^~~
../target/riscv/kvm/kvm-cpu.c:539:5: note: in expansion of macro 'KVM_RISCV_GET_CSR'
  539 |     KVM_RISCV_GET_CSR(cs, env, sstatus, env->mstatus);
      |     ^~~~~~~~~~~~~~~~~
../target/riscv/kvm/kvm-cpu.c:536:9: note: shadowed declaration is here
  536 |     int ret = 0;
      |         ^~~

../target/riscv/kvm/kvm-cpu.c: In function 'kvm_riscv_put_regs_csr':
../target/riscv/kvm/kvm-cpu.c:98:13: error: declaration of 'ret' shadows a previous local [-Werror=shadow=compatible-local]
   98 |         int ret = kvm_set_one_reg(cs, RISCV_CSR_REG(env, csr), &reg); \
      |             ^~~
../target/riscv/kvm/kvm-cpu.c:556:5: note: in expansion of macro 'KVM_RISCV_SET_CSR'
  556 |     KVM_RISCV_SET_CSR(cs, env, sstatus, env->mstatus);
      |     ^~~~~~~~~~~~~~~~~
../target/riscv/kvm/kvm-cpu.c:553:9: note: shadowed declaration is here
  553 |     int ret = 0;
      |         ^~~

The macros are doing early returns for non-zero returns and the local
'ret' variable for both functions is used just to do 'return 0', so
remove them from kvm_riscv_get_regs_csr() and kvm_riscv_put_regs_csr()
and do a straight 'return 0' in the end.

For good measure let's also rename the 'ret' variables in
KVM_RISCV_GET_CSR() and KVM_RISCV_SET_CSR() to '_ret' to make them more
resilient to these kind of errors.

f7767ca301 target/arm: Disable SME if SVE is disabled
There is no architectural requirement that SME implies SVE, but
our implementation currently assumes it. (FEAT_SME_FA64 does
imply SVE.) So if you try to run a CPU with eg "-cpu max,sve=off"
you quickly run into an assert when the guest tries to write to
SMCR_EL1:

#6  0x00007ffff4b38e96 in __GI___assert_fail
    (assertion=0x5555566e69cb "sm", file=0x5555566e5b24 "../../target/arm/helper.c", line=6865, function=0x5555566e82f0 <__PRETTY_FUNCTION__.31> "sve_vqm1_for_el_sm") at ./assert/assert.c:101
#7  0x0000555555ee33aa in sve_vqm1_for_el_sm (env=0x555557d291f0, el=2, sm=false) at ../../target/arm/helper.c:6865

#9  0x0000555555ee3724 in smcr_write (env=0x555557d291f0, ri=0x555557da23b0, value=2147483663) at ../../target/arm/helper.c:6995

#11 0x00007fff60056781 in code_gen_buffer ()

Avoid this unsupported and slightly odd combination by
disabling SME when SVE is not present.

551ef0fa05 hw/audio/virtio-sound: mark the device as unmigratable
The virtio-sound device is currently not migratable. QEMU crashes
on the source machine at some point during the migration with a
segmentation fault.

Even with this bug fixed, the virtio-sound device doesn't migrate
the state of the audio streams. For example, running streams leave
the device on the destination machine in a broken condition.

Mark the device as unmigratable until these issues have been fixed.

Commit d921fea338 ("ui/vnc-clipboard: fix infinite loop in
inflate_buffer (CVE-2023-3255)") removed this hunk, but it is still
required, because it can happen that stream.avail_in becomes zero
before coming across a return value of Z_STREAM_END in the loop.

This fixes the host->guest direction of the clipboard with noVNC and
TigerVNC as clients.

53a939f1bf ui/gtk-egl: move function calls back to regular code path
Commit 6f189a08c1 ("ui/gtk-egl: Check EGLSurface before doing
scanout") introduced a regression when QEMU is running with a
virtio-gpu-gl-device on a host under X11. After the guest has
initialized the virtio-gpu-gl-device, the guest screen only
shows "Display output is not active.".

Commit 6f189a08c1 moved all function calls in
gd_egl_scanout_texture() to a code path which is only called
once after gd_egl_init() succeeds in gd_egl_scanout_texture().
Move all function calls in gd_egl_scanout_texture() back to
the regular code path so they get always called if one of the
gd_egl_init() calls was successful.
