Commit 9d8bf2d1 moved the softmmu slow path out of line and introduce a
regression at the same time by always calling tcg_out_tlb_load with
is_load=1. This makes impossible to run any significant code under

There are three ACPI tables: 'linker_data', 'rsdp' and 'table_data'. They are
used differently. Two of them are being copied before using and only the copy
is used later. But the third is used directly. Because of that we need to free
two tables completely and delete only wrapper for the third one.

Differently from older versions, SMBIOS version 2.6 is explicit about
the encoding of UUID fields:
> Although RFC 4122 recommends network byte order for all fields, the PC
> industry (including the ACPI, UEFI, and Microsoft specifications) has
> consistently used little-endian byte encoding for the first three fields:
> time_low, time_mid, time_hi_and_version. The same encoding, also known as
> wire format, should also be used for the SMBIOS representation of the UUID.
>
> The UUID {00112233-4455-6677-8899-AABBCCDDEEFF} would thus be represented
> as 33 22 11 00 55 44 77 66 88 99 AA BB CC DD EE FF.
The dmidecode tool implements this and decodes the above "wire format"
when SMBIOS version >= 2.6. We moved from SMBIOS version 2.4 to 2.8 when
we started building the SMBIOS entry point inside QEMU, on commit
c97294ec1b.
Change smbios_build_type_1_table() to encode the UUID as specified.
To make sure we won't change the guest-visible UUID when upgrading to a
newer QEMU version, keep the old behavior on pc-*-2.1 and older.

The event idx in virtio is an effective way to reduce the number of
interrupts and exits of the guest. When the guest puts an request
into the virtio ring, it doesn't exit immediately to inform the
backend. Instead, the guest checks the "avail" event idx to determine
the notification.
In virtqueue_pop, when a request is poped, the current avail event
idx should be set to the number of vq->last_avail_idx.

Current support for bus master (clearing OK bit) together with the need to
support guests which do not enable PCI bus mastering, leads to extra state in
VIRTIO_PCI_FLAG_BUS_MASTER_BUG bit, which isn't robust in case of cross-version
migration for the case when guests use the device before setting DRIVER_OK.
Rip out this code, and replace it:
- Modern QEMU doesn't need VIRTIO_PCI_FLAG_BUS_MASTER_BUG
so just drop it for latest machine type.
- For compat machine types, set PCI_COMMAND if DRIVER_OK
is set.
As this is needed for 2.1 for both pc and ppc, move PC_COMPAT macros from pc.h
to a new common header.

Commit 261747f1 ("vl: Use MachineClass instead of global QEMUMachine
list") broke the ordering of the machine types in the user-visible output
of
qemu-system-XXXX -M \?
This occurred because registration was rebased from a manually maintained
linked list to GLib hash tables:
qemu_register_machine()
type_register()
type_register_internal()
type_table_add()
g_hash_table_insert()
and because the listing was rebased accordingly, from the traversal of the
list to the traversal of the hash table (rendered as an ad-hoc list):
machine_parse()
object_class_get_list(TYPE_MACHINE)
object_class_foreach()
g_hash_table_foreach()
The current order is a "random" one, for practical purposes, which is
annoying for users.
Introduce new members QEMUMachine.family and MachineClass.family, allowing
machine types to be "clustered". Introduce a comparator function that
establishes a total ordering between machine types, ordering machine types
in the same family next to each other. In machine_parse(), list the
supported machine types sorted with the comparator function.
The comparator function:
- sorts whole families before standalone machine types,
- sorts whole families between each other in alphabetically increasing
order,
- sorts machine types inside the same family in alphabetically decreasing
order,
- sorts standalone machine types between each other in alphabetically
increasing order.
After this patch, all machine types are considered standalone, and
accordingly, the output is alphabetically ascending. This will be refined
in the following patches.

QEMU currently allows the number of VCPUs to not be a multiple of the
number of threads per socket, but the smbios socket count calculation
introduced by commit c97294ec1b doesn't
take that into account, triggering an assertion. e.g.:
$ ./x86_64-softmmu/qemu-system-x86_64 -smp 4,sockets=2,cores=6,threads=1
qemu-system-x86_64: /home/ehabkost/rh/proj/virt/qemu/hw/i386/smbios.c:825: smbios_get_tables: Assertion `smbios_smp_sockets >= 1' failed.
Aborted (core dumped)
Socket count calculation doesn't belong to smbios.c and should
eventually be moved to the main SMP topology configuration code. But
while we don't move the code, at least make it correct by rounding up
the division.

commit 5193e5fb (tap: factor out common tap initialization)
introduce net_init_tap_one(). But it's inappropriate that
we close fd in net_init_tap_one(), we should lay it in the
caller, becuase some callers needn't to close it if we get
the fd by monitor_handle_fd_param().
On the other hand, in other exceptional branches fd isn't
closed, so that's incomplete anyway.

Put "success" parent reporting in os_setup_post() to after
all other initializers which may also fail, to the very end,
so more possible failure cases are reported properly to the

In case of -daemonize, we write non-zero to the daemon
pipe only if pidfile creation failed, so the parent will
report error about pidfile problem. There's no need to
make special case for this, since all other errors are
reported by the child just fine. Let the parent report
error and simplify logic in os_daemonize().
This way, we don't need os_pidfile_error() function, since
it only prints error now, so put the error reporting printf
into the only place where qemu_create_pidfile() is called,
in vl.c.
While at it, fix wrong indentation in os_daemonize().

Reviewed-by: Gonglei <arei.gonglei@huawei.com>
When asked to -daemonize, we fork a child and setup a pipe between
it and parent to pass exit status. os-posix.c used global fds[2]
array for that, but actually only the writing side of the pipe is
needed to be global, and this name is really too generic. Use
just one interger for the writing side of the pipe, and name it
daemon_pipe to be more understandable than cryptic fds[1].

dump_iterate() dumps blocks in a loop. Eventually, get_next_block()
returns "no more". We then call dump_completed(). But we neglect to
break the loop! Broken in commit 4c7e251a.
Because of that, we dump the last block again. This attempts to write
to s->fd, which fails if we're lucky. The error makes dump_iterate()
return failure. It's the only way it can ever return.
Theoretical: if we're not so lucky, something else has opened something
for writing and got the same fd. dump_iterate() then keeps looping,
messing up the something else's output, until a write fails, or the
process mercifully terminates.
The obvious fix is to restore the return lost in commit 4c7e251a. But
the root cause of the bug is needlessly opaque loop control. Replace it
by a clean do ... while loop.
This makes the badly chosen return values of get_next_block() more
visible. Cleaning that up is outside the scope of this bug fix.

It looks like smbd always logs to /var/log/samba/log.$progname
even if config file specifies different logfile -- when it needs
to log something before completing reading the config file. But
if it can't open it for writing, it fails and exits. Tell smbd
to use our temp dir as logbase (-l option) to avoid that.
The same option is used by samba3 and samba4, so there should
be no incompatible changes.

This reverts commit e5048d15ce.
qemu_create_pidfile() is only created from main(), and there,
if that function returns failure, os_pidfile_error() function
is called, to, guess that, report error (which is done differently
whenever we're daemonizing or not).
qemu_create_pidfile() function has several error returns, this
lockf() failure is one of them, there are others (another shown
in the patch context too).
So this patch makes whole thing inconsistent at least.
If we need to show error message when we're daemonizing, it
looks like we should modify os_pidfile_error() routine to always
report error and only after that check for daemon mode. This way
all errors will be reported the same way.

Currently, when the preallocating guest memory process fails, a not
so helpful error message is printed out:
# virsh start migt10
error: Failed to start domain migt10
error: internal error: process exited while connecting to monitor:
os_mem_prealloc: failed to preallocate pages
From the error message it's not clear at the first glance where the
problem lies. However, changing the error message might give users a
clue.
