Tao Xu 2744ece809 hw/arm: simplify arm_load_dtb
In struct arm_boot_info, kernel_filename, initrd_filename and
kernel_cmdline are copied from from MachineState. This patch add
MachineState as a parameter into arm_load_dtb() and move the copy chunk
of kernel_filename, initrd_filename and kernel_cmdline into
arm_load_kernel().

Philippe Mathieu-Daudé 9f591a5d95 trace: Clarify DTrace/SystemTap help message
Most tracing backends are implemented within QEMU, except the
DTrace/SystemTap backends.

One side effect is when running 'qemu -trace help', an incomplete
list of trace events is displayed when using the DTrace/SystemTap
backends.

This is partly due to trace events registered as modules with
trace_init(), and since the events are not used within QEMU,
the linker optimize and remove the unused modules (which is
OK in this particular case).
Currently only the events compiled in trace-root.o and in the
last trace.o member of libqemuutil.a are linked, resulting in
an incomplete list of events.

To avoid confusion, improve the help message, recommending to
use the proper systemtap script to display the events list.

Before:

  $ lm32-softmmu/qemu-system-lm32 -trace help 2>&1 | wc -l
  70

After:

  $ lm32-softmmu/qemu-system-lm32 -trace help
  Run 'qemu-trace-stap list qemu-system-lm32' to print a list
  of names of trace points with the DTrace/SystemTap backends.

  $ qemu-trace-stap list qemu-system-lm32 | wc -l
  1136

We'll need to check a part of qiov soon, so implement it now.

Optimization with align down to 4 * sizeof(long) is dropped due to:
1. It is strange: it aligns length of the buffer, but where is a
   guarantee that buffer pointer is aligned itself?
2. buffer_is_zero() is a better place for optimizations and it has
   them.

So, we need to update qemu_iovec_destroy to support destroying such

Anthony PERARD 705be57094 xen-bus: Avoid rewriting identical values to xenstore
When QEMU receives a xenstore watch event suggesting that the "state"
of the frontend changed, it records this in its own state but it also
re-write the value back into xenstore even so there were no change.
This triggers an unnecessary xenstore watch event which QEMU will
process again (and maybe the frontend as well). Also QEMU could
potentially write an already old value.

Anthony PERARD cb32314607 xen-bus: Fix backend state transition on device reset
When a frontend wants to reset its state and the backend one, it
starts with setting "Closing", then waits for the backend (QEMU) to do
the same.

But when QEMU is setting "Closing" to its state, it triggers an event
(xenstore watch) that re-execute xen_device_backend_changed() and set
the backend state to "Closed". QEMU should wait for the frontend to
set "Closed" before doing the same.

Before setting "Closed" to the backend_state, we are also going to
check if there is a frontend. If that the case, when the backend state
is set to "Closing" the frontend should react and sets its state to
"Closing" then "Closed". The backend should wait for that to happen.

The xen_[rw]?mb() macros defined in ring.h can't be used and the fact
that there are gated behind __XEN_INTERFACE_VERSION__ means that it
needs to be defined somewhere. QEMU doesn't implement interfaces with
the Xen hypervisor so defining __XEN_INTERFACE_VERSION__ is pointless.
This leads to:
    include/hw/xen/io/ring.h:47:5: error: "__XEN_INTERFACE_VERSION__"

Cleanup ring.h. The xen_*mb() macros are already defined in xenctrl.h

  target/alpha: fix tlb_fill trap_arg2 value for instruction fetch

Aurelien Jarno cb1de55a83 target/alpha: fix tlb_fill trap_arg2 value for instruction fetch
Commit e41c945297 ("target/alpha: Convert to CPUClass::tlb_fill")
slightly changed the way the trap_arg2 value is computed in case of TLB
fill. The type of the variable used in the ternary operator has been
changed from an int to an enum. This causes the -1 value to not be
sign-extended to 64-bit in case of an instruction fetch. The trap_arg2
ends up with 0xffffffff instead of 0xffffffffffffffff. Fix that by
changing the -1 into -1LL.

This fixes the execution of user space processes in qemu-system-alpha.

Raphael Norwitz 5d4c1ed3d4 vhost-user-scsi: prevent using uninitialized vqs
Of the 3 virtqueues, seabios only sets cmd, leaving ctrl
and event without a physical address. This can cause
vhost_verify_ring_part_mapping to return ENOMEM, causing
the following logs:

qemu-system-x86_64: Unable to map available ring for ring 0
qemu-system-x86_64: Verify ring failure on region 0

The qemu commit e6cc11d64f
has already resolved the issue for vhost scsi devices but
the fix was never applied to vhost-user scsi devices.

Stefan Hajnoczi f0f8100287 util/async: hold AioContext ref to prevent use-after-free
The tests/test-bdrv-drain /bdrv-drain/iothread/drain test case does the
following:

1. The preadv coroutine calls aio_bh_schedule_oneshot() and then yields.
2. The one-shot BH executes in another AioContext.  All it does is call
   aio_co_wakeup(preadv_co).
3. The preadv coroutine is re-entered and returns.

There is a race condition in aio_co_wake() where the preadv coroutine
returns and the test case destroys the preadv IOThread.  aio_co_wake()
can still be running in the other AioContext and it performs an access
to the freed IOThread AioContext.

Here is the race in aio_co_schedule():

  QSLIST_INSERT_HEAD_ATOMIC(&ctx->scheduled_coroutines,
                            co, co_scheduled_next);
  <-- race: co may execute before we invoke qemu_bh_schedule()!
  qemu_bh_schedule(ctx->co_schedule_bh);

So if co causes ctx to be freed then we're in trouble.  Fix this problem
by holding a reference to ctx.

Marc-André Lureau 9459f75413 docker.py: add podman support
Add a --engine option to select either docker, podman or auto.

Among other advantages, podman allows to run rootless & daemonless
containers, fortunately sharing compatible CLI with docker.

With current podman, we have to use a uidmap trick in order to be able
to rw-share the ccache directory with the container user.

With a user 1000, the default mapping is:                                                                                                                                                                         1000 (host) -> 0 (container).
So write access to /var/tmp/ccache ends will end with permission
denied error.

With "--uidmap 1000:0:1 --uidmap 0:1:1000", the mapping is:
1000 (host) -> 0 (container, 1st namespace) -> 1000 (container, 2nd namespace).
(the rest is mumbo jumbo to avoid holes in the range of UIDs)

A future podman version may have an option such as --userns-keep-uid.

David Hildenbrand 2d3bb388ad s390x/mmu: Better storage key reference and change bit handling
Any access sets the reference bit. In case we have a read-fault, we
should not allow writes to the TLB entry if the change bit was not
already set.

This is a preparation for proper storage-key reference/change bit handling
in TCG and a fix for KVM whereby read accesses would set the change
bit (old KVM versions without the ioctl to carry out the translation).

David Hildenbrand 5b773a1107 s390x/tcg: Flush the TLB of all CPUs on SSKE and RRBE
Whenever we modify a storage key, we should flush the TLBs of all CPUs,
so the MMU fault handling code can properly consider the changed storage
key (to e.g., properly set the reference and change bit on the next
accesses).

These functions are barely used in modern Linux guests, so the performance
implications are neglectable for now.

This is a preparation for better reference and change bit handling for
TCG, which will require more MMU changes.

David Hildenbrand 3096ffd368 s390x/tcg: Rework MMU selection for instruction fetches
Instructions are always fetched from primary address space, except when
in home address mode. Perform the selection directly in cpu_mmu_index().

get_mem_index() is only used to perform data access, instructions are
fetched via cpu_lduw_code(), which translates to cpu_mmu_index(env, true).

We don't care about restricting the access permissions of the TLB
entries anymore, as we no longer enter PRIMARY entries into the
SECONDARY MMU. Cleanup related code a bit.

Let's select the ASC before calling the function. This is a prepararion
to remove the ASC magic depending on the access mode from mmu_translate.

There is currently no way to distinguish if we have code or data access.
For now, we were using code access, because especially when debugging with
the gdbstub, we want to read and disassemble what we single-step.

Note: KVM guest can now no longer be crashed using qmp/hmp/gdbstub if they
happen to be in AR mode.
