This reverts a part of commit 8a47e8e. We're having second thoughts
on the QAPI schema (and thus the external interface), and haven't
reached consensus, yet. Issues include:
* BlockdevOptionsRbd member @password-secret isn't actually a
password, it's a key generated by Ceph.
* We're not sure where member @password-secret belongs (see the
previous commit).
* How @password-secret interacts with settings from a configuration
file specified with @conf is undocumented.
Let's avoid painting ourselves into a corner now, and revert the
feature for 2.9.
Note that users can still configure an authentication key with a
configuration file. They probably do that anyway if they use Ceph
outside QEMU as well.

This reverts half of commit 0a55679. We're having second thoughts on
the QAPI schema (and thus the external interface), and haven't reached
consensus, yet. Issues include:
* The implementation uses deprecated rados_conf_set() key
"auth_supported". No biggie.
* The implementation makes -drive silently ignore invalid parameters
"auth" and "auth-supported.*.X" where X isn't "auth". Fixable (in
fact I'm going to fix similar bugs around parameter server), so
again no biggie.
* BlockdevOptionsRbd member @password-secret applies only to
authentication method cephx. Should it be a variant member of
RbdAuthMethod?
* BlockdevOptionsRbd member @user could apply to both methods cephx
and none, but I'm not sure it's actually used with none. If it
isn't, should it be a variant member of RbdAuthMethod?
* The client offers a *set* of authentication methods, not a list.
Should the methods be optional members of BlockdevOptionsRbd instead
of members of list @auth-supported? The latter begs the question
what multiple entries for the same method mean. Trivial question
now that RbdAuthMethod contains nothing but @type, but less so when
RbdAuthMethod acquires other members, such the ones discussed above.
* How BlockdevOptionsRbd member @auth-supported interacts with
settings from a configuration file specified with @conf is
undocumented. I suspect it's untested, too.
Let's avoid painting ourselves into a corner now, and revert the
feature for 2.9.
Note that users can still configure authentication methods with a
configuration file. They probably do that anyway if they use Ceph
outside QEMU as well.
Further note that this doesn't affect use of key "auth-supported" in
-drive file=rbd:...:key=value.
qemu_rbd_array_opts()'s parameter @type now must be RBD_MON_HOST,
which is silly. This will be cleaned up shortly.

runtime_opts is used for three different purposes:
* qemu_rbd_open() uses it to accept options it recognizes, such as
"pool" and "image". Other .bdrv_open() methods do it similarly.
* qemu_rbd_open() accepts additional list-valued options
auth-supported and server, with the help of qemu_rbd_array_opts().
The list elements are again dictionaries. qemu_rbd_array_opts()
uses runtime_opts to accept their members. Thus, runtime_opts
contains recognized sub-sub-options "auth", "host", "port" in
addition to recognized options. No other block driver does that.
* qemu_rbd_create() uses it to convert the QDict produced by
qemu_rbd_parse_filename() to QemuOpts. No other block driver does
that. The keys produced by qemu_rbd_parse_filename() are "pool",
"image", "snapshot", "conf", "user" and "keyvalue-pairs".
qemu_rbd_open() accepts these, so no additional ones here.
This is a confusing mess. Dates back to commit 0f9d252. First step
to clean it up is documenting runtime_opts.desc[]:
* Reorder entries to match the QAPI schema, like we do in other block
drivers.
* Document why the schema's "server" and "auth-supported" aren't in
.desc[].
* Document why "keyvalue-pairs", "host", "port" and "auth" are in
.desc[], but not the schema.
* Delete "filename", because none of the three users actually uses it.
This fixes -drive to reject parameter filename instead of silently
ignoring it.

We laboriously enforce that parameter values are between one and some

from is unclear.
Drop the length checking. The limits librbd actually imposes must be
checked by librbd anyway.
There's one minor complication: BDRVRBDState member name is a
fixed-size array. Depends on the length limit. Make it a pointer to

9pfs: fix file descriptor leak
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
For a packed struct like 'P9Hdr' the fields within it may not be
aligned as much as the natural alignment for their types. This means
it is not valid to pass the address of such a field to a function
like le32_to_cpus() which operate on uint32_t* and assume alignment.
Doing this results in a SIGBUS on hosts like SPARC which have strict
alignment requirements.
Use ldl_le_p() instead, which is specified to correctly handle
unaligned pointers.

Success for bdrv_flush() means that all previously written data is safe
on disk. For fdatasync(), the best semantics we can hope for on Linux
(without O_DIRECT) is that all data that was written since the last call
was successfully written back. Therefore, and because we can't redo all
writes after a flush failure, we have to give up after a single
fdatasync() failure. After this failure, we would never be able to make
the promise that a successful bdrv_flush() makes.

After the switch to reading replies in a coroutine, nothing is
reentering pending receive coroutines if the connection hangs.
Move nbd_recv_coroutines_enter_all to the reply read coroutine,
which is the place where hangups are detected. nbd_teardown_connection
can simply wait for the reply read coroutine to detect the hangup
and clean up after itself.
This wouldn't be enough though because nbd_receive_reply returns 0

The multithreaded TCG implementation exposed deadlocks in the win32
condition variables: as implemented, qemu_cond_broadcast waited on
receivers, whereas the pthreads API it was intended to emulate does
not. This was causing a deadlock because broadcast was called while
holding the IO lock, as well as all possible waiters blocked on the
same lock.
This patch replaces all the custom synchronisation code for mutexes
and condition variables with native Windows primitives (SRWlocks and
condition variables) with the same semantics as their POSIX

vnc server in reverse mode (qemu -vnc localhost:$nr,reverse) interprets
$nr as display number (i.e. with 5900 offset) in recent qemu versions.
Historical and documented behavior is interpreting $nr as port number
though. So we should bring code and documentation in line.
Given that default listening port for viewers is 5500 the 5900 offset is
pretty inconvinient, because it is simply impossible to connect to port
5500. So, lets fix the code not the docs.

virtio_input_send buffers input events until it sees a SYNC. Then it
either sends or drops the entire batch, depending on whether eventq
has enough space available. The case to avoid here is partial sends
where only part of the batch would get to the guest.
Using virtqueue_get_avail_bytes to check the state of eventq was not
correct. The queue may have a smaller number of larger buffers
available so bytes may be enough but the batch would still not be
possible to send, leading to the "Huh? No vq elem available" error.
Instead of checking available bytes, this patch optimistically pops
buffers from the queue and puts them back in case it runs out of
space and the batch needs to be dropped.

hw/i386/trace-events has an amdvi_mmio_read trace that is used for
both normal reads (listing the register name, address, size, and
offset) and for an error case (abusing the register name to show
an error message, the address to show the maximum value supported,
then shoehorning address and size into the size and offset
parameters). The change from a wide address to a narrower size
parameter could truncate a (rather-large) bogus read attempt, so
it's better to create a separate dedicated trace with correct types,
rather than abusing the trace mechanism. Broken since its
introduction in commit d29a09c.
[Change trace event argument type from hwaddr to uint64_t since
user-defined types should not be used for trace events. This fixes a
build failure with LTTng UST.

hw/scsi/trace-events lists cmd as the first parameter for both
megasas_iovec_overflow and megasas_iovec_underflow, but the caller
was mistakenly passing cmd->iov_size twice instead of the command
index. Also, trace_megasas_abort_invalid is called with parameters
in the wrong order. Broken since its introduction in commit
e8f943c3.

block/trace-events lists the parameters for mirror_yield
consistently with other mirror events (cnt just after s, like in
mirror_before_sleep; in_flight last, like in mirror_yield_in_flight).
But the callers were passing parameters in the wrong order, leading
to poor trace messages, including type truncation when there are
more than 4G dirty sectors involved. Broken since its introduction
in commit bd48bde.
While touching this, ensure that all callers use the same type
(uint64_t) for cnt, as a later patch will enable the compiler to do
stricter type-checking.

Commit 9a6d1ac assumed that 'qom-type' could be removed from QemuOpts
with no ill effects. However, this command line proves otherwise:
$ ./x86_64-softmmu/qemu-system-x86_64 -nodefaults -nographic -qmp stdio \
-object rng-random,filename=/dev/urandom,id=rng0 \
-device virtio-rng-pci,rng=rng0
qemu-system-x86_64: -object rng-random,filename=/dev/urandom,id=rng0: Parameter 'qom-type' is missing
Fix the regression by restoring qom-type in opts after its temporary
removal that was needed for the duration of user_creatable_add_opts().

Just a single bugfix in this batch. It's not strictly in ppc code,
though it's for the pseries machine's benefit. Eduardo suggested it
go through my tree however.
