f2e3af29b7 file-posix: Drop s->lock_fd
The lock_fd field is not strictly necessary because transferring locked
bytes from old fd to the new one shouldn't fail anyway. This spares the
user one fd per image.

2996ffad3a file-posix: Skip effectiveless OFD lock operations
If we know we've already locked the bytes, don't do it again; similarly
don't unlock a byte if we haven't locked it. This doesn't change the
behavior, but fixes a corner case explained below.

Libvirt had an error handling bug that an image can get its (ownership,
file mode, SELinux) permissions changed (RHBZ 1584982) by mistake behind
QEMU. Specifically, an image in use by Libvirt VM has:

    $ ls -lhZ b.img
    -rw-r--r--. qemu qemu system_u:object_r:svirt_image_t:s0:c600,c690 b.img

Trying to attach it a second time won't work because of image locking.
And after the error, it becomes:

    $ ls -lhZ b.img
    -rw-r--r--. root root system_u:object_r:virt_image_t:s0 b.img

Then, we won't be able to do OFD lock operations with the existing fd.
In other words, the code such as in blk_detach_dev:

    blk_set_perm(blk, 0, BLK_PERM_ALL, &error_abort);

can abort() QEMU, out of environmental changes.

This patch is an easy fix to this and the change is regardlessly
reasonable, so do it.

d52e1a0e96 blockdev: Consistently use snapshot_node_name in external_snapshot_prepare()
In the function external_snapshot_prepare() we have a
BlockdevSnapshotSync struct, which has the usual combination
of has_snapshot_node_name and snapshot_node_name fields for an
optional field. We set up a local variable
        const char *snapshot_node_name =
            s->has_snapshot_node_name ? s->snapshot_node_name : NULL;

and then mostly use "if (!snapshot_node_name)" for checking
whether we have a snapshot node name. The exception is that in
one place we check s->has_snapshot_node_name instead. This
confuses Coverity (CID 1396473), which thinks it might be
possible to get here with s->has_snapshot_node_name true but
snapshot_node_name NULL, and warns that the call to
qdict_put_str() will segfault in that case.

Make the code consistent and unconfuse Coverity by using
the same check for this conditional that we do in the rest
of the surrounding code.

63d5341f85 blockdev: handle error on block latency histogram set error
Function block_latency_histogram_set may return error, but qapi ignore this.
This can be reproduced easily by qmp command:
virsh qemu-monitor-command INSTANCE '{"execute":"x-block-latency-histogram-set",
"arguments":{"device":"drive-virtio-disk1","boundaries":[10,200,40]}}'
In fact this command does not work, but we still get success result.

qmp_x_block_latency_histogram_set is a batch setting API, report error ASAP.

435cc3e4d5 hw/acpi/nvdimm: Don't take address of fields in packed structs
Taking the address of a field in a packed struct is a bad idea, because
it might not be actually aligned enough for that pointer type (and
thus cause a crash on dereference on some host architectures). Newer
versions of clang warn about this. Avoid the bug by not using the
"modify in place" byte swapping functions.

Patch produced with scripts/coccinelle/inplace-byteswaps.cocci.

6cdc2d189c pulseaudio: process audio data in smaller chunks
The rate of pulseaudio absorbing the audio stream is used to control the
the rate of the guests audio stream.  When the emulated hardware uses
small chunks (like intel-hda does) we need small chunks on the audio
backend side too, otherwise that feedback loop doesn't work very well.

c0188e69d3 bt: Mark the bluetooth subsystem as deprecated
It has been unmaintained since years, and there were only trivial or
tree-wide changes to the related files since many years, so the
code is likely very bitrotten and broken. For example the following
segfaults as soon as as you press a key:

 qemu-system-x86_64 -usb -device usb-bt-dongle -bt hci -bt device:keyboard

Since we are not aware of anybody using bluetooth with the current
version of QEMU, let's mark the subsystem as deprecated, with a special
request for the users to write to the qemu-devel mailing list in case
they still use it (so we could revert the deprecation status in that
case).

5c75f3adbb slirp: fork_exec(): create and connect child socket before fork()
Currently fork_exec() fork()s, and then creates and connects the
child socket which it uses for communication with the parent in
the child process. This is awkward because the child has no
mechanism to report failure back to the parent, which might end
up blocked forever in accept(). The child code also has an issue
pointed out by Coverity (CID 1005727), where if the qemu_socket()
call fails it will pass -1 as a file descriptor to connect().

Fix these issues by moving the creation of the child's end of
the socket to before the fork(), where we are in a position to
handle a possible failure.

4ded9bb54c slirp: Remove code that handles socreate() failure
Now that socreate() can never fail, we can remove the code
that was trying to handle that situation.

In particular this removes code in tcp_connect() that
provoked Coverity to complain (CID 1005724): in
 closesocket(accept(inso->s, (struct sockaddr *)&addr, &addrlen));
if the accept() call fails then we pass closesocket() -1
instead of a valid file descriptor.

c41868152a slirp: Don't pass possibly -1 fd to send()
Coverity complains (CID 1005726) that we might pass -1 as the fd
argument to send() in slirp_send(), because we previously checked for
"so->s == -1 && so->extra".  The case of "so->s == -1 but so->extra
NULL" should not in theory happen, but it is hard to guarantee
because various places in the code do so->s = qemu_socket(...) and so
will end up with so->s == -1 on failure, and not all the paths which
call that always throw away the socket in that case (eg
tcp_fconnect()).  So just check specifically for the condition and
fail slirp_send().

5b76ef50f6 9p: write lock path in v9fs_co_open2()
The assumption that the fid cannot be used by any other operation is
wrong. At least, nothing prevents a misbehaving client to create a
file with a given fid, and to pass this fid to some other operation
at the same time (ie, without waiting for the response to the creation
request). The call to v9fs_path_copy() performed by the worker thread
after the file was created can race with any access to the fid path
performed by some other thread. This causes use-after-free issues that
can be detected by ASAN with a custom 9p client.

Unlike other operations that only read the fid path, v9fs_co_open2()
does modify it. It should hence take the write lock.

 * An as-of-yet-unwritten fix to the third issue that Basian pointed out.
 * A fix to our fflags bug, which is currently coupled to some CSR
   refactoring that I don't think is OK for 3.1.
 
 I'm at Plumbers next week (and I think Alistair is there too?), but I'll
 try to find a way to squeeze in as much as possible.

Add the spapr cap SPAPR_CAP_NESTED_KVM_HV to be used to control the
availability of nested kvm-hv to the level 1 (L1) guest.

Assuming a hypervisor with support enabled an L1 guest can be allowed to
use the kvm-hv module (and thus run it's own kvm-hv guests) by setting:
-machine pseries,cap-nested-hv=true
or disabled with:
-machine pseries,cap-nested-hv=false

The ptcr (partition table control register) is used to store the address
and size of the partition table. For nested kvm-hv we have a level 1
guest register the location of it's partition table with the hypervisor.
Thus to support migration we need to be able to read this out of kvm
and restore it post migration.

d07945e78e ppc/pnv: check size before data buffer access
While performing PowerNV memory r/w operations, the access length
'sz' could exceed the data[4] buffer size. Add check to avoid OOB
access.

b8edea50a7 target/ppc: fix mtmsr instruction for icount
This patch fixes processing of mtmsr instructions in icount mode.
In this mode writing to interrupt/peripheral state is controlled
by can_do_io flag. This flag must be set explicitly before helper
function invocation.

1bbd6272a1 hw/ppc/mac_newworld: Free openpic_irqs array after use
In ppc_core99_init(), we allocate an openpic_irqs array, which
we then use to collect up the various qemu_irqs which we're
going to connect to the interrupt controller. Once we've
called sysbus_connect_irq() to connect them all up, the
array is no longer required, but we forgot to free it.

Since board init is only run once at startup, the memory
leak is not a significant one.

Spotted by Coverity: CID 1192916.

4fc4c6a53d spapr_pci: convert g_malloc() to g_new()
When allocating an array, it is a recommended coding practice to call
g_new(FooType, n) instead of g_malloc(n * sizeof(FooType)) because
it takes care to avoid overflow when calculating the size of the
allocated block and it returns FooType *, which allows the compiler
to perform type checking.
