Commit 032a74a1c0fcdd5fd1c69e56126b4c857ee36611
("virtio-net: byteswap virtio-net header") breaks any layout by
requiring out_sg[0].iov_len >= n->guest_hdr_len. Fixing this by
copying header to temporary buffer if swap is needed, and then use
this buffer as part of out_sg.

Calling a function pointer that was cast from an incompatible function
results in undefined behavior. 'void *' isn't compatible with 'struct
XXX *', so we can't cast to nettle_cipher_func, but have to provide a
wrapper. (Conversion from 'void *' to 'struct XXX *' might require
computation, which won't be done if we drop argument's true type, and
pointers can have different sizes so passing arguments on stack would
bug.)
Having two different prototypes based on nettle version doesn't make
this solution any nicer.

memory_region_present() leaks a reference to a MemoryRegion in the
case "mr == container". While fixing it, avoid reference counting
altogether for memory_region_present(), by using RCU only.
The return value could in principle be already invalid immediately
after memory_region_present returns, but presumably the caller knows
that and it's using memory_region_present to probe for devices that
are unpluggable, or something like that. The RCU critical section
is needed anyway, because it protects as->current_map.

This patch allow to limit number of heads using qxl driver. By default
qxl driver is not limited on any kind on head use so can decide to use
as much heads.
libvirt has this as a video card parameter (actually set to 1 but not
used). This parameter will allow to limit setting a use can do (which
could be confusing).

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

W10 insider has a bug where it ignores CPUID level and interprets
CPUID.(EAX=07H, ECX=0H) incorrectly, because CPUID in fact returned
CPUID.(EAX=04H, ECX=0H); this resulted in execution of unsupported
instructions.
While it's a Windows bug, there is no reason to emulate incorrect level.
I used http://instlatx64.atw.hu/ as a source of CPUID and checked that
it matches Penryn Xeon X5472, Westmere Xeon W3520, SandyBridge i5-2540M,
and Haswell i5-4670T.
kvm64 and qemu64 were bumped to 0xD to allow all available features for
them (and to avoid the same Windows bug).

hw/arm/boot: Increase fdt alignment
target-arm: Fix broken SCTLR_EL3 reset
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
|

The Linux kernel on aarch64 creates a page table entry at early bootup
that spans the 2MB range on memory spanning the fdt start address:
[ ALIGN_DOWN(fdt, 2MB) ... ALIGN_DOWN(fdt, 2MB) + 2MB ]
This means that when our current 4k alignment happens to fall at the end
of the aligned region, Linux tries to access memory that is not mapped.
The easy fix is to instead increase the alignment to 2MB, making Linux's
logic always succeed.
We leave the existing 4k alignment for 32bit kernels to not cause any
regressions due to space constraints.

The SCTLR_EL3 cpreg definition was implicitly resetting the
register state to 0, which is both wrong and clashes with
the reset done via the SCTLR definition (since sctlr[3]
is unioned with sctlr_s). This went unnoticed until recently,
when an unrelated change (commit a903c449b41f105aa) happened to
perturb the order of enumeration through the cpregs hashtable for
reset such that the erroneous reset happened after the correct one
rather than before it. Fix this by marking SCTLR_EL3 as an alias,
so its reset is left up to the AArch32 view.

When a LWL, LWR, LDL or LDR instruction triggers a page fault, QEMU
currently reports the aligned address in CP0 BadVAddr, while the Windows
NT kernel expects the unaligned address.
This patch adds a byte access with the unaligned address at the
beginning of the LWL/LWR/LDL/LDR instructions to possibly trigger a page
fault and fill the QEMU TLB.

For the MIPS N64 ABI when QEMU reads the break/trap instruction so that
it can inspect the break/trap code it reads 8 rather than 4 bytes
which means it finds the code field from the instruction after the
break/trap instruction. This then causes the break/trap handling
code to fail because it does not understand the code number.
The fix forces QEMU to always read 4 bytes of instruction data rather
than deciding how much to read based on the ABI.

Commit df4b1024526cae3479da3492d6371fd4a7324a03 introduced global_state
section. But it only filled the state while doing migration. While
doing a savevm, we stored an empty string as state. So when we did a
loadvm, it complained that state was invalid.

Currently if qemu is connected to a curl source (eg. web server), and
the web server fails / times out / dies, you always see a bogus EIO
"Input/output error".
For example, choose a large file located on any local webserver which
you control:
$ qemu-img convert -p http://example.com/large.iso /tmp/test
Once it starts copying the file, stop the webserver and you will see
qemu-img fail with:
qemu-img: error while reading sector 61440: Input/output error
This patch does two things: Firstly print the actual error from curl
so it doesn't get lost. Secondly, change EIO to EPROTO. EPROTO is a
POSIX.1 compatible errno which more accurately reflects that there was
a protocol error, rather than some kind of hardware failure.
After this patch is applied, the error changes to:
$ qemu-img convert -p http://example.com/large.iso /tmp/test
qemu-img: curl: transfer closed with 469989 bytes remaining to read
qemu-img: error while reading sector 16384: Protocol error

Reclaim the dirty bitmap if an incremental backup block job is
cancelled. The ret variable may be 0 when the job is cancelled so it's
not enough to check ret < 0.

Draining is not necessary, I/O can happen as soon as the
commit coroutine yields. Draining can be necessary before
reopening the file for read/write, or while modifying the
backing file chain, but that is done separately in
bdrv_reopen_multiple or bdrv_close; this particular
bdrv_drain_all does nothing for that.

Before, we only yield after initializing dirty bitmap, where the QMP
command would return. That may take very long, and guest IO will be
blocked.
Add sleep points like the later mirror iterations.

The diag288 watchdog is no sysbus device, therefore it doesn't get
triggered on resets automatically using dc->reset.
Let's register the reset handler manually, so we get correctly notified
again when a system reset was requested. Also reset the watchdog on
subsystem resets that don't trigger a full system reset.
