It's useful to know how much space can be occupied by qcow2 persistent
bitmaps, even though such metadata is unrelated to the guest-visible
data. Report this value as an additional QMP field, present when
measuring an existing image and output format that both support
bitmaps. Update iotest 178 and 190 to updated output, as well as new
coverage in 190 demonstrating non-zero values made possible with the
recently-added qemu-img bitmap command (see 3b51ab4b).
The new 'bitmaps size:' field is displayed automatically as part of
'qemu-img measure' any time it is present in QMP (that is, any time
both the source image being measured and destination format support
bitmaps, even if the measurement is 0 because there are no bitmaps
present). If the field is absent, it means that no bitmaps can be
copied (source, destination, or both lack bitmaps, including when
measuring based on size rather than on a source image). This behavior
is compatible with an upcoming patch adding 'qemu-img convert
--bitmaps': that command will fail in the same situations where this
patch omits the field.
The addition of a new field demonstrates why we should always
zero-initialize qapi C structs; while the qcow2 driver still fully
populates all fields, the raw and crypto drivers had to be tweaked to
avoid uninitialized data.
Consideration was also given towards having a 'qemu-img measure
--bitmaps' which errors out when bitmaps are not possible, and
otherwise sums the bitmaps into the existing allocation totals rather
than displaying as a separate field, as a potential convenience
factor. But this was ultimately decided to be more complexity than
necessary when the QMP interface was sufficient enough with bitmaps
remaining a separate field.

It actually never worked with libvirt, as auto-generated names are

It's unsafe and useless to migrate by auto-generated node-names, so

Important thing for bitmap migration is to select destination block
node to obtain the migrated bitmap.
Prepatch, on source we use bdrv_get_device_or_node_name() to identify
the node, and on target we do bdrv_lookup_bs.
bdrv_get_device_or_node_name() returns blk name only for direct
children of blk. So, bitmaps of direct children of blks are migrated by
blk name and others - by node name.
Old libvirt is unprepared to bitmap migration by node-name,
node-names are mostly auto-generated. So actually only migration by blk
name works for it.
Newer libvirt will use new interface (which will be added soon) to
specify node-mapping for bitmaps migration explicitly. Still, let's
improve the current behavior a bit.
Now, consider classic libvirt migrations assisted by mirror block job:
mirror block job inserts filter, so our source is not a direct child of
blk, and bitmaps are migrated by node-names. And this just doesn't work
with auto-generated node names.
Let's fix it by using blk-name even if some implicit filters are
inserted.
Note2: we, of course, can't skip filters and use blk name to migrate
bitmaps in filtered node by blk name for this blk if these filters have
named bitmaps which should be migrated.

Currently all pipelines of the gitlab CI are failing, except for the
"build-user" pipeline. There is an issue with the default container
image (likely Debian stable) where they imported something bad in one
of the system headers:
/usr/include/linux/swab.h: In function '__swab':
/builds/huth/qemu/include/qemu/bitops.h:20:34: error: "sizeof" is not
defined, evaluates to 0 [-Werror=undef]
#define BITS_PER_LONG (sizeof (unsigned long) * BITS_PER_BYTE)
We could maybe work-around this issue or wait for the default containers
to get fixed, but considering that we use Ubuntu (and thus Debian-style)
CI in Travis already to a very large extent, we should consider to use
some RPM-based distros in our gitlab CI instead. Thus let's change the
failing pipelines to use Fedora and CentOS (and also one Ubuntu 19.10,
since 20.04 is broken, too) now.

If SELinux is setup without 'execmem' permission for qemu, all mmap
with (PROT_WRITE | PROT_EXEC) will fail and print a warning in
SELinux log.
If "nvlink2-mr" memory allocation fails (fist diff), it will cause
guest NUMA nodes to not be correctly configured (V100 memory will
not be visible for guest, nor its NUMA nodes).
Not having 'execmem' permission is intesting for virtual machines to
avoid buffer-overflow based attacks, and it's adopted in distros
like RHEL.
So, removing the PROT_EXEC flag seems the right thing to do.
Browsing some other code that mmaps memory for usage with
memory_region_init_ram_device_ptr, I could notice it's usual to
not have PROT_EXEC (only PROT_READ | PROT_WRITE), so it should be
no problem around this.

gdbstub shouldn't silently change guest visible state when doing address
translation. Since the R/C bits can only be updated when handling a MMU
fault, let's reuse the cause_excp flag and rename it to guest_visible.
While here drop a not very useful comment.
This was found while reading the code. I could verify that this affects
both powernv and pseries, but I failed to observe any actual bug.

It is the job of the ppc_radix64_get_fully_qualified_addr() function
which is called at the beginning of ppc_radix64_xlate() to set both
lpid *and* pid. It doesn't buy us anything to initialize them first.
Worse, a bug in ppc_radix64_get_fully_qualified_addr(), eg. failing to
set either lpid or pid, would be undetectable by static analysis tools
like coverity.
Some recent versions of gcc (eg. gcc-9.3.1-2.fc30) may still think
that lpid or pid is used uninitialized though, so this also adds
default cases in the switch statements to make it clear this cannot
happen.

On reboot, all memory that was previously added using object_add and
device_add is placed in this DIMM area.
The new SPAPR_LMB_FLAGS_HOTREMOVABLE flag helps Linux to put this memory in
the correct memory zone, so no unmovable allocations are made there,
allowing the object to be easily hot-removed by device_del and
object_del.
This new flag was accepted in Power Architecture documentation.
