Subject: [PATCH] rtl8139: fix large_send_mss divide-by-zero
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If the driver sets large_send_mss to 0 then a divide-by-zero occurs.
Even if the division wasn't a problem, the for loop that emits MSS-sized
packets would never terminate.
Solve these issues by skipping offloading when large_send_mss=0.
This issue was found by OSS-Fuzz as part of Alexander Bulekov's device
fuzzing work. The reproducer is:

Subject: [PATCH] block/monitor: Fix crash when executing HMP commit
hmp_commit() calls blk_is_available() from a non-coroutine context (and
in the main loop). blk_is_available() is a co_wrapper_mixed_bdrv_rdlock
function, and in the non-coroutine context it calls AIO_WAIT_WHILE(),
which crashes if the aio_context lock is not taken before.

Subject: [PATCH] ui: Fix pixel colour channel order for PNG screenshots
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When we take a PNG screenshot the ordering of the colour channels in
the data is not correct, resulting in the image having weird
colouring compared to the actual display. (Specifically, on a
little-endian host the blue and red channels are swapped; on
big-endian everything is wrong.)
This happens because the pixman idea of the pixel data and the libpng
idea differ. PIXMAN_a9r8g8b8 defines that pixels are 32-bit values,
with A in bits 24-31, R in bits 16-23, G in bits 8-15 and B in bits
0-7. This means that on little-endian systems the bytes in memory
are
B G R A
and on big-endian systems they are
A R G B
libpng, on the other hand, thinks of pixels as being a series of
values for each channel, so its format PNG_COLOR_TYPE_RGB_ALPHA
always wants bytes in the order
R G B A
This isn't the same as the pixman order for either big or little
endian hosts.
The alpha channel is also unnecessary bulk in the output PNG file,
because there is no alpha information in a screenshot.
To handle the endianness issue, we already define in ui/qemu-pixman.h
various PIXMAN_BE_* and PIXMAN_LE_* values that give consistent
byte-order pixel channel formats. So we can use PIXMAN_BE_r8g8b8 and
PNG_COLOR_TYPE_RGB, which both have an in-memory byte order of
R G B
and 3 bytes per pixel.
(PPM format screenshots get this right; they already use the
PIXMAN_BE_r8g8b8 format.)

Subject: [PATCH] softfloat: Fix the incorrect computation in float32_exp2
The float32_exp2 function is computing wrong exponent of 2.
For example, with the following set of values {0.1, 2.0, 2.0, -1.0},
the expected output would be {1.071773, 4.000000, 4.000000, 0.500000}.
Instead, the function is computing {1.119102, 3.382044, 3.382044, -0.191022}
Looking at the code, the float32_exp2() attempts to do this
2 3 4 5 n
x x x x x x x
e = 1 + --- + --- + --- + --- + --- + ... + --- + ...
1! 2! 3! 4! 5! n!
But because of the typo it ends up doing
x x x x x x x
e = 1 + --- + --- + --- + --- + --- + ... + --- + ...
1! 2! 3! 4! 5! n!
This is because instead of the xnp which holds the numerator, parts_muladd
is using the xp which is just 'x'. Commit '572c4d862ff2' refactored this
function, and mistakenly used xp instead of xnp.

Subject: [PATCH] hw/pci: Disable PCI_ERR_UNCOR_MASK register for machine type
< 8.0
Since it's implementation on v8.0.0-rc0, having the PCI_ERR_UNCOR_MASK
set for machine types < 8.0 will cause migration to fail if the target
QEMU version is < 8.0.0 :
qemu-system-x86_64: get_pci_config_device: Bad config data: i=0x10a read: 40 device: 0 cmask: ff wmask: 0 w1cmask:0
qemu-system-x86_64: Failed to load PCIDevice:config
qemu-system-x86_64: Failed to load e1000e:parent_obj
qemu-system-x86_64: error while loading state for instance 0x0 of device '0000:00:02.0/e1000e'
qemu-system-x86_64: load of migration failed: Invalid argument
The above test migrated a 7.2 machine type from QEMU master to QEMU 7.2.0,
with this cmdline:
./qemu-system-x86_64 -M pc-q35-7.2 [-incoming XXX]
In order to fix this, property x-pcie-err-unc-mask was introduced to
control when PCI_ERR_UNCOR_MASK is enabled. This property is enabled by
default, but is disabled if machine type <= 7.2.

Subject: [PATCH] block: Fix use after free in blockdev_mark_auto_del()
job_cancel_locked() drops the job list lock temporarily and it may call
aio_poll(). We must assume that the list has changed after this call.
Also, with unlucky timing, it can end up freeing the job during
job_completed_txn_abort_locked(), making the job pointer invalid, too.
For both reasons, we can't just continue at block_job_next_locked(job).
Instead, start at the head of the list again after job_cancel_locked()
and skip those jobs that we already cancelled (or that are completing
anyway).

Subject: [PATCH] block: Consistently call bdrv_activate() outside coroutine
Migration code can call bdrv_activate() in coroutine context, whereas
other callers call it outside of coroutines. As it calls other code that
is not supposed to run in coroutines, standardise on running outside of
coroutines.
This adds a no_co_wrapper to switch to the main loop before calling
bdrv_activate().

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] block: Don't call no_coroutine_fns in qmp_block_resize()
This QMP handler runs in a coroutine, so it must use the corresponding
no_co_wrappers instead.
