Subject: [PATCH] crypto: run qcrypto_pbkdf2_count_iters in a new thread
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
CPU time accounting in the kernel has been demonstrated to have a
sawtooth pattern[1][2]. This can cause the getrusage system call to
not be as accurate as we are expecting, which can cause this calculation
to stall.
The kernel discussions shows that this inaccuracy happens when CPU time
gets big enough, so this patch changes qcrypto_pbkdf2_count_iters to run
in a fresh thread to avoid this inaccuracy. It also adds a sanity check
to fail the process if CPU time is not accounted.

Subject: [PATCH] hw/audio/virtio-sound: fix heap buffer overflow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Currently, the guest may write to the device configuration space,
whereas the virtio sound device specification in chapter 5.14.4
clearly states that the fields in the device configuration space
are driver-read-only.
Remove the set_config function from the virtio_snd class.
This also prevents a heap buffer overflow. See QEMU issue #2296.

Subject: [PATCH] hw/intc/arm_gic: fix spurious level triggered interrupts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On GICv2 and later, level triggered interrupts are pending when either
the interrupt line is asserted or the interrupt was made pending by a
GICD_ISPENDRn write. Making a level triggered interrupt pending by
software persists until either the interrupt is acknowledged or cleared
by writing GICD_ICPENDRn. As long as the interrupt line is asserted,
the interrupt is pending in any case.
This logic is transparently implemented in gic_test_pending() for
GICv1 and GICv2. The function combines the "pending" irq_state flag
(used for edge triggered interrupts and software requests) and the
line status (tracked in the "level" field). However, we also
incorrectly set the pending flag on a guest write to GICD_ISENABLERn
if the line of a level triggered interrupt was asserted. This keeps
the interrupt pending even if the line is de-asserted after some
time.
This incorrect logic is a leftover of the initial 11MPCore GIC
implementation. That handles things slightly differently to the
architected GICv1 and GICv2. The 11MPCore TRM does not give a lot of
detail on the corner cases of its GIC's behaviour, and historically
we have not wanted to investigate exactly what it does in reality, so
QEMU's GIC model takes the approach of "retain our existing behaviour
for 11MPCore, and implement the architectural standard for later GIC
revisions".
On that basis, commit 8d999995e45c10 in 2013 is where we added the
"level-triggered interrupt with the line asserted" handling to
gic_test_pending(), and we deliberately kept the old behaviour of
gic_test_pending() for REV_11MPCORE. That commit should have added
the "only if 11MPCore" condition to the setting of the pending bit on
writes to GICD_ISENABLERn, but forgot it.
Add the missing "if REV_11MPCORE" condition, so that our behaviour
on GICv1 and GICv2 matches the GIC architecture requirements.

Subject: [PATCH] softmmu/physmem: fix memory leak in dirty_memory_extend()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
As reported by Peter, we might be leaking memory when removing the
highest RAMBlock (in the weird ram_addr_t space), and adding a new one.
We will fail to realize that we already allocated bitmaps for more
dirty memory blocks, and effectively discard the pointers to them.
Fix it by getting rid of last_ram_page() and by remembering the number
of dirty memory blocks that have been allocated already.
While at it, let's use "unsigned int" for the number of blocks, which
should be sufficient until we reach ~32 exabytes.
Looks like this leak was introduced as we switched from using a single
bitmap_zero_extend() to allocating multiple bitmaps:
bitmap_zero_extend() relies on g_renew() which should have taken care of
this.

In case the display surface uses a shared buffer (i.e. uses vga vram
directly instead of a shadow) go unshare the buffer before clearing it.
This avoids vga memory corruption, which in turn fixes unblanking not
working properly with X11.

Subject: [PATCH] target/i386: fix size of EBP writeback in gen_enter()
The calculation of FrameTemp is done using the size indicated by mo_pushpop()
before being written back to EBP, but the final writeback to EBP is done using
the size indicated by mo_stacksize().
In the case where mo_pushpop() is MO_32 and mo_stacksize() is MO_16 then the
final writeback to EBP is done using MO_16 which can leave junk in the top
16-bits of EBP after executing ENTER.
Change the writeback of EBP to use the same size indicated by mo_pushpop() to
ensure that the full value is written back.

cheery-pick from 2cc0e449d17310877fb28a942d4627ad22bb68ea
The move to decodetree flipped the inequality test for the VEC / VSX
MSR facility check.
This caused application crashes under Linux, where these facility
unavailable interrupts are used for lazy-switching of VEC/VSX register
sets. Getting the incorrect interrupt would result in wrong registers
being loaded, potentially overwriting live values and/or exposing
stale ones.

cheery-pick from 8bded2e73e80823a67f730140788a3c5e60bf4b5
The XT check for the lxvx/stxvx instructions is currently
inverted. This was introduced during the move to decodetree.
>From the ISA:
Chapter 7. Vector-Scalar Extension Facility
Load VSX Vector Indexed X-form
lxvx XT,RA,RB
if TX=0 & MSR.VSX=0 then VSX_Unavailable()
if TX=1 & MSR.VEC=0 then Vector_Unavailable()
...
Let XT be the value 32×TX + T.
The code currently does the opposite:
if (paired || a->rt >= 32) {
REQUIRE_VSX(ctx);
} else {
REQUIRE_VECTOR(ctx);
}
This was already fixed for lxv/stxv at commit "2cc0e449d1 (target/ppc:
Fix lxv/stxv MSR facility check)", but the indexed forms were missed.

Subject: [PATCH] target/riscv/kvm: tolerate KVM disable ext errors
Running a KVM guest using a 6.9-rc3 kernel, in a 6.8 host that has zkr
enabled, will fail with a kernel oops SIGILL right at the start. The
reason is that we can't expose zkr without implementing the SEED CSR.
Disabling zkr in the guest would be a workaround, but if the KVM doesn't
allow it we'll error out and never boot.
In hindsight this is too strict. If we keep proceeding, despite not
disabling the extension in the KVM vcpu, we'll not add the extension in
the riscv,isa. The guest kernel will be unaware of the extension, i.e.
it doesn't matter if the KVM vcpu has it enabled underneath or not. So
it's ok to keep booting in this case.
Change our current logic to not error out if we fail to disable an
extension in kvm_set_one_reg(), but show a warning and keep booting. It
is important to throw a warning because we must make the user aware that
the extension is still available in the vcpu, meaning that an
ill-behaved guest can ignore the riscv,isa settings and use the
extension.
The case we're handling happens with an EINVAL error code. If we fail to
disable the extension in KVM for any other reason, error out.
We'll also keep erroring out when we fail to enable an extension in KVM,
since adding the extension in riscv,isa at this point will cause a guest
malfunction because the extension isn't enabled in the vcpu.

Subject: [PATCH] tests: bump QOS_PATH_MAX_ELEMENT_SIZE again
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We "fixed" a bug with LTO builds with 100c459f194 (tests/qtest: bump
up QOS_PATH_MAX_ELEMENT_SIZE) but it seems it has triggered again.
The array is sized according to the maximum anticipated length of a
path on the graph. However, the worst case for a depth-first search is
to push all nodes on the graph. So it's not really LTO, it depends on
the ordering of the constructors.
Lets be more assertive raising QOS_PATH_MAX_ELEMENT_SIZE to make it go
away again.

Subject: [PATCH] ui/gtk: Draw guest frame at refresh cycle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Draw routine needs to be manually invoked in the next refresh
if there is a scanout blob from the guest. This is to prevent
a situation where there is a scheduled draw event but it won't
happen bacause the window is currently in inactive state
(minimized or tabified). If draw is not done for a long time,
gl_block timeout and/or fence timeout (on the guest) will happen
eventually.
v2: Use gd_gl_area_draw(vc) in gtk-gl-area.c

Subject: [PATCH] ui/sdl2: set swap interval explicitly when OpenGL is enabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Before 176e3783f2ab (ui/sdl2: OpenGL window context)
SDL_CreateRenderer was called unconditionally setting
the swap interval to 0. Since SDL_CreateRenderer is now no
longer called when OpenGL is enabled, the swap interval is
no longer set explicitly and vsync handling depends on
the environment settings which may lead to a performance
regression with virgl as reported in
https://gitlab.com/qemu-project/qemu/-/issues/2565
Restore the old vsync handling by explicitly calling
SDL_GL_SetSwapInterval if OpenGL is enabled.
Fixes: 176e3783f2ab (ui/sdl2: OpenGL window context)

Subject: [PATCH] virtio-net: drop too short packets early
Reproducer from https://gitlab.com/qemu-project/qemu/-/issues/1451
creates small packet (1 segment, len = 10 == n->guest_hdr_len),
then destroys queue.
"if (n->host_hdr_len != n->guest_hdr_len)" is triggered, if body creates
zero length/zero segment packet as there is nothing after guest header.
qemu_sendv_packet_async() tries to send it.
slirp discards it because it is smaller than Ethernet header,
but returns 0 because tx hooks are supposed to return total length of data.
0 is propagated upwards and is interpreted as "packet has been sent"
which is terrible because queue is being destroyed, nobody is waiting for TX
to complete and assert it triggered.
Fix is discard such empty packets instead of sending them.
Length 1 packets will go via different codepath:
virtqueue_push(q->tx_vq, elem, 0);
virtio_notify(vdev, q->tx_vq);
g_free(elem);
and aren't problematic.

MIME-Version: 1.0

Commit d152cdd6f6 ("virtio: use virtio accessor to access packed event")
switched using of address_space_read_cached() to virito_lduw_phys_cached()
to access packed descriptor event.
When we used address_space_read_cached(), we needed to call
virtio_tswap16s() to handle the endianess of the field, but
virito_lduw_phys_cached() already handles it internally, so we no longer
need to call virtio_tswap16s() (as the commit had done for `off_wrap`,
but forgot for `flags`).

cherry-pick from 98e77e3dd8dd6e7aa9a7dffa60f49c8c8a49d4e3
When reading input audio in the virtio-snd input callback,
virtio_snd_pcm_in_cb(), we do not check whether the iov can actually fit
the data buffer. This is because we use the buffer->size field as a
total-so-far accumulator instead of byte-size-left like in TX buffers.
This triggers an out of bounds write if the size of the virtio queue
element is equal to virtio_snd_pcm_status, which makes the available
space for audio data zero. This commit adds a check for reaching the
maximum buffer size before attempting any writes.
