Commit a3a3d8c7 introduced a segfault bug while checking for
'dc->vmsd->unmigratable' which caused QEMU to crash when trying to add
devices which do no set their 'dc->vmsd' yet while initialization.
Place a 'dc->vmsd' check prior to it so that we do not segfault for
such devices.
NOTE: This doesn't compromise the functioning of --only-migratable
option as all the unmigratable devices do set their 'dc->vmsd'.
Introduce a new function check_migratable() and move the
only_migratable check inside it, also use stubs to avoid user-mode qemu
build failures.

To fix migration between 2.7 and 2.8, some fields have
been renamed and managed with the help of a PHB property
(pre_2_8_migration):
5c4537b spapr: Fix 2.7<->2.8 migration of PCI host bridge
So we need to add them to the white list:
dma_liobn[0],
mem_win_addr, mem_win_size,
io_win_addr, io_win_size
become
mig_liobn,
mig_mem_win_addr, mig_mem_win_size,
mig_io_win_addr, mig_io_win_size

Fixed type case in assert to uintptr_t rather than uint64_t
|
|
Make VMS_ARRAY_OF_POINTER cope with null pointers. Previously the
reward for trying to migrate an array with some null pointers in it was
an illegal memory access, that is a swift and painless death of the
process. Let's make vmstate cope with this scenario.
The general approach is, when we encounter a null pointer (element),
instead of following the pointer to save/load the data behind it, we
save/load a placeholder. This way we can detect if we expected a null
pointer at the load side but not null data was saved instead.

Currently vmstate_base_addr does several things: it pinpoints the field
within the struct, possibly allocates memory and possibly does the first
pointer dereference. Obviously allocation is needed only for load.
Let us split up the functionality in vmstate_base_addr and move the
address manipulations (that is everything but the allocation logic) to
load and save so it becomes more obvious what is actually going on. Like
this all the address calculations (and the handling of the flags
controlling these) is in one place and the sequence is more obvious.
The newly introduced function vmstate_handle_alloc also fixes the
allocation for the unused VMS_VBUFFER|VMS_MULTIPLY|VMS_ALLOC scenario
and is substantially simpler than the original vmstate_base_addr.
In load and save some asserts are added so it's easier to debug
situations where we would end up with a null pointer dereference.

The vmstate_(load|save)_state start out with an a void *opaque pointing
to some struct, and manipulate one or more elements of one field within
that struct.
First the field within the struct is pinpointed as opaque + offset, then
if this is a pointer the pointer is dereferenced to obtain a pointer to
the first element of the vmstate field. Pointers to further elements if
any are calculated as first_element + i * element_size (where i is the
zero based index of the element in question).
Currently base_addr and addr is used as a variable name for the pointer
to the first element and the pointer to the current element being
processed. This is suboptimal because base_addr is somewhat
counter-intuitive (because obtained as base + offset) and both base_addr
and addr not very descriptive (that we have a pointer should be clear
from the fact that it is declared as a pointer).
Let make things easier to understand by renaming base_addr to first_elem
and addr to curr_elem. This has the additional benefit of harmonizing
with other names within the scope (n_elems, vmstate_n_elems).

Using QMP, the error message of 'migrate_set_downtime' was displaying
the values in milliseconds, being misleading with the command that
accepts the value in seconds:
{ "execute": "migrate_set_downtime", "arguments": {"value": 3000}}
{"error": {"class": "GenericError", "desc": "Parameter 'downtime_limit'
expects an integer in the range of 0 to 2000000 milliseconds"}}
This message is also seen in HMP when trying to set the same
parameter:
(qemu) migrate_set_parameter downtime-limit 3000000
Parameter 'downtime_limit' expects an integer in the range of 0 to
2000000 milliseconds
To allow for a proper error message when using QMP, a validation
of the user input was added in 'qmp_migrate_set_downtime'.

XkbGetKeyboard does not work in XWayland and even on non-Wayland
X11 servers its use is discouraged:
https://bugs.freedesktop.org/show_bug.cgi?id=89240
This resolves a problem whereby QEMU prints
"could not lookup keycode name"
on startup when running under XWayland. Keymap handling is
however still broken after this commit, since Xwayland is
reporting a keymap we can't handle
"unknown keycodes `(unnamed)', please report to qemu-devel@nongnu.org"
NB, native Wayland support (which is the default under GTK3) is
not affected - only XWayland (which can be requested with GDK_BACKEND
on GTK3, and is the only option for GTK2).

Coverity points out (CID 1005725) that an error-exit path in tcp_listen()
will try to close(s) even if the reason it got there was that the
qemu_socket() failed and s was never opened. Not only that, this isn't even
the right function to use, because we need closesocket() to do the right
thing on Windows. Change to using the right function and only calling it if
needed.

Check the return value from qemu_socket() rather than trying to
pass it to bind() as an fd argument even if it's negative.
This wouldn't have caused any negative consequences, because
it won't be a valid fd number and the bind call will fail;
but Coverity complains (CID 1005723).

blk_insert_bs() and block job related functions will soon require an
opened block node (permission calculations will involve the block
driver), so let our tests be consistent with the real users in this
respect.

We should not try to assign a not yet opened node as the backing file,
because as soon as the permission system is added it will fail. The
just added bdrv_new_open_driver() function is the right tool to open a
file with an internal driver, use it.
In case anyone wonders whether that magic fake backing file to trigger a
special action on 'commit' actually works today: No, not for me. One
reason is that we've been adding a raw format driver on top for several
years now and raw doesn't support commit. Other reasons include that the
backing file isn't writable and the driver doesn't support reopen, and
it's also size 0 and the driver doesn't support bdrv_truncate. All of
these are easily fixable, but then 'commit' ended up in an infinite loop
deep in the vvfat code for me, so I thought I'd best leave it alone. I'm
not really sure what it was supposed to do anyway.

This function allows to create more or less normal BlockDriverStates
even for BlockDrivers that aren't globally registered (e.g. helper
filters for block jobs).
