block: Pass BdrvChild ** to replace_child_noperm
bdrv_replace_child_noperm() modifies BdrvChild.bs, and can potentially
set it to NULL. That is dangerous, because BDS parents generally assume
that their children's .bs pointer is never NULL. We therefore want to
let bdrv_replace_child_noperm() set the corresponding BdrvChild pointer
to NULL, too.
This patch lays the foundation for it by passing a BdrvChild ** pointer
to bdrv_replace_child_noperm() so that it can later use it to NULL the
BdrvChild pointer immediately after setting BdrvChild.bs to NULL.
(We will still need to undertake some intermediate steps, though.)

block: Drop detached child from ignore list
bdrv_attach_child_common_abort() restores the parent's AioContext. To
do so, the child (which was supposed to be attached, but is now detached
again by this abort handler) is added to the ignore list for the
AioContext changing functions.
However, since we modify a BDS's children list in the BdrvChildClass's
.attach and .detach handlers, the child is already effectively detached
from the parent by this point. We do not need to put it into the ignore
list.
Use this opportunity to clean up the empty line structure: Keep setting
the ignore list, invoking the AioContext function, and freeing the
ignore list in blocks separated by empty lines.

ppc/mmu_helper.c: do not truncate 'ea' in booke206_invalidate_ea_tlb()
'tlbivax' is implemented by gen_tlbivax_booke206() via
gen_helper_booke206_tlbivax(). In case the TLB needs to be flushed,
booke206_invalidate_ea_tlb() is called. All these functions, but
booke206_invalidate_ea_tlb(), uses a 64-bit effective address 'ea'.
booke206_invalidate_ea_tlb() uses an uint32_t 'ea' argument that
truncates the original 'ea' value for apparently no particular reason.
This function retrieves the tlb pointer by calling booke206_get_tlbm(),
which also uses a target_ulong address as parameter - in this case, a
truncated 'ea' address. All the surrounding logic considers the
effective TLB address as a 64 bit value, aside from the signature of
booke206_invalidate_ea_tlb().
Last but not the least, PowerISA 2.07B section 6.11.4.9 [2] makes it
clear that the effective address "EA" is a 64 bit value.
Commit
01662f3e5133 introduced this code and no changes were made ever
since. An user detected a problem with tlbivax [1] stating that this
address truncation was the cause. This same behavior might be the source
of several subtle bugs that were never caught.
For all these reasons, this patch assumes that this address truncation
is the result of a mistake/oversight of the original commit, and changes
booke206_invalidate_ea_tlb() 'ea' argument to 'vaddr'.

sgx: Reset the vEPC regions during VM reboot
For bare-metal SGX on real hardware, the hardware provides guarantees
SGX state at reboot. For instance, all pages start out uninitialized.
The vepc driver provides a similar guarantee today for freshly-opened
vepc instances, but guests such as Windows expect all pages to be in
uninitialized state on startup, including after every guest reboot.
Qemu can invoke the ioctl to bring its vEPC pages back to uninitialized
state. There is a possibility that some pages fail to be removed if they
are SECS pages, and the child and SECS pages could be in separate vEPC
regions. Therefore, the ioctl returns the number of EREMOVE failures,
telling Qemu to try the ioctl again after it's done with all vEPC regions.

spapr_numa.c: fix FORM1 distance-less nodes
Commit
71e6fae3a99 fixed an issue with FORM2 affinity guests with NUMA
nodes in which the distance info is absent in
machine_state->numa_state->nodes. This happens when QEMU adds a default
NUMA node and when the user adds NUMA nodes without specifying the
distances.
During the discussions of the forementioned patch [1] it was found that
FORM1 guests were behaving in a strange way in the same scenario, with
the kernel seeing the distances between the nodes as '160', as we can
see in this example with 4 NUMA nodes without distance information:
$ numactl -H
available: 4 nodes (0-3)
(...)
node distances:
node 0 1 2 3
0: 10 160 160 160
1: 160 10 160 160
2: 160 160 10 160
3: 160 160 160 10
Turns out that we have the same problem with FORM1 guests - we are
calculating associativity domain using zeroed values. And as it also
turns out, the solution from
71e6fae3a99 applies to FORM1 as well.
This patch creates a wrapper called 'get_numa_distance' that contains
the logic used in FORM2 to define node distances when this information
is absent. This helper is then used in all places where we need to read
distance information from machine_state->numa_state->nodes. That way
we'll guarantee that the NUMA node distance is always being curated
before being used.
After this patch, the FORM1 guest mentioned above will have the
following topology:
$ numactl -H
available: 4 nodes (0-3)
(...)
node distances:
node 0 1 2 3
0: 10 20 20 20
1: 20 10 20 20
2: 20 20 10 20
3: 20 20 20 10
This is compatible with what FORM2 guests and other archs do in this
case.

accel/tcg: Register a force_rcu notifier
A TCG vCPU doing a busy loop systematicaly hangs the QEMU monitor
if the user passes 'device_add' without argument. This is because
drain_cpu_all() which is called from qmp_device_add() cannot return
if readers don't exit read-side critical sections. That is typically
what busy-looping TCG vCPUs do:
int cpu_exec(CPUState *cpu)
{
[...]
rcu_read_lock();
[...]
while (!cpu_handle_exception(cpu, &ret)) {
// Busy loop keeps vCPU here
}
[...]
rcu_read_unlock();
return ret;
}
For MTTCG, have all vCPU threads register a force_rcu notifier that will
kick them out of the loop using async_run_on_cpu(). The notifier is called
with the rcu_registry_lock mutex held, using async_run_on_cpu() ensures
there are no deadlocks.
For RR, a single thread runs all vCPUs. Just register a single notifier
that kicks the current vCPU to the next one.

rcu: Introduce force_rcu notifier
The drain_rcu_call() function can be blocked as long as an RCU reader
stays in a read-side critical section. This is typically what happens
when a TCG vCPU is executing a busy loop. It can deadlock the QEMU
monitor as reported in https://gitlab.com/qemu-project/qemu/-/issues/650 .
This can be avoided by allowing drain_rcu_call() to enforce an RCU grace
period. Since each reader might need to do specific actions to end a
read-side critical section, do it with notifiers.
Prepare ground for this by adding a notifier list to the RCU reader
struct and use it in wait_for_readers() if drain_rcu_call() is in
progress. An API is added for readers to register their notifiers.
This is largely based on a draft from Paolo Bonzini.

monitor: Fix find_device_state() for IDs containing slashes
Recent commit
6952026120 "monitor: Tidy up find_device_state()"
assumed the function's argument is "the device's ID or QOM path" (as
documented for device_del). It's actually either an absolute QOM
path, or a QOM path relative to /machine/peripheral/. Such a relative
path is a device ID when it doesn't contain a slash. When it does,
the function now always fails. Broke iotest 200, which uses relative
path "vda/virtio-backend".
It fails because object_resolve_path_component() resolves just one
component, not a relative path.
The obvious function to resolve relative paths is
object_resolve_path(). It picks a parent automatically. Too much
magic, we want to specify the parent. Create new
object_resolve_path_at() for that, and use it in find_device_state().

qapi: deprecate drive-backup
Modern way is using blockdev-add + blockdev-backup, which provides a
lot more control on how target is opened.
As example of drive-backup problems consider the following:
User of drive-backup expects that target will be opened in the same
cache and aio mode as source. Corresponding logic is in
drive_backup_prepare(), where we take bs->open_flags of source.
It works rather bad if source was added by blockdev-add. Assume source
is qcow2 image. On blockdev-add we should specify aio and cache options
for file child of qcow2 node. What happens next:
drive_backup_prepare() looks at bs->open_flags of qcow2 source node.
But there no BDRV_O_NOCAHE neither BDRV_O_NATIVE_AIO: BDRV_O_NOCAHE is
places in bs->file->bs->open_flags, and BDRV_O_NATIVE_AIO is nowhere,
as file-posix parse options and simply set s->use_linux_aio.
The documentation is updated in a minimal way, so that drive-backup is
noted only as a deprecated command, and blockdev-backup used in most of
places.

Apart from that, this patchset is mostly a lot of updates to TCG

target/ppc, hw/ppc: Change maintainers
As our day jobs and interests have moved onto other things, Greg and I have
been struggling to keep on top of maintainership of target/ppc and
associated pieces like the pseries and powernv machine types, with their
platform specific devices.
We've therefore discussed and plan to transfer maintainership to Cédric Le
Goater (primary) and Daniel Henrique Barboza (backup). Cédric and Daniel
have been actively contributing to the area for some time, and they're
supported in this by their current employer, IBM, who has an obvious
interest in the platform.
Greg and I do plan to stay around in some capacity for at least the next
6 months, providing reviews and advice to assist the new maintainers into
the role.
