qxl: switch display on entering VGA
Since commit
cd958edb1fae85d, same size console resize is skipped. This
change broke QXL incoming migration in VGA mode,
qemu_spice_display_switch() is no longer called during qxl_post_load(),
because default message surface is of the same size, and during
displaychangelistener registration, PCIQXLDevice.mode is
QXL_MODE_UNDEFINED. This triggers a later crash on refresh:

9pfs: clear migration blocker at session reset
The migration blocker survives a device reset: if the guest mounts a 9p
share and then gets rebooted with system_reset, it will be unmigratable
until it remounts and umounts the 9p share again.
This happens because the migration blocker is supposed to be cleared when
we put the last reference on the root fid, but virtfs_reset() wrongly calls
free_fid() instead of put_fid().
This patch fixes virtfs_reset() so that it honor the way fids are supposed
to be manipulated: first get a reference and later put it back when you're
done.

main-loop: Acquire main_context lock around os_host_main_loop_wait.
When running virt-rescue the serial console hangs from time to time.
Virt-rescue runs an ordinary Linux kernel "appliance", but there is
only a single idle process running inside, so the qemu main loop is
largely idle. With virt-rescue >= 1.37 you may be able to observe the
hang by doing:
$ virt-rescue -e ^] --scratch
><rescue> while true; do ls -l /usr/bin; done
The hang in virt-rescue can be resolved by pressing a key on the
serial console.
Possibly with the same root cause, we also observed hangs during very
early boot of regular Linux VMs with a serial console. Those hangs
are extremely rare, but you may be able to observe them by running
this command on baremetal for a sufficiently long time:
$ while libguestfs-test-tool -t 60 >& /tmp/log ; do echo -n . ; done
(Check in /tmp/log that the failure was caused by a hang during early
boot, and not some other reason)

This patch exactly implements Paolo's suggestion in that paragraph.
This fixes the serial console hang in my testing, across 3 different
physical machines (AMD, Intel Core i7 and Intel Xeon), over many hours
of automated testing. I wasn't able to reproduce the early boot hangs
(but as noted above, these are extremely rare in any case).

qcow2: Discard unaligned tail when wiping image
There is a subtle difference between the fast (qcow2v3 with no
extra data) and slow path (qcow2v2 format [aka 0.10], or when a
snapshot is present) of qcow2_make_empty(). The slow path fails
to discard the final (partial) cluster of an unaligned image.
The problem stems from the fact that qcow2_discard_clusters() was
silently ignoring sub-cluster head and tail on unaligned requests.
A quick audit of all callers shows that qcow2_snapshot_create() has
always passed a cluster-aligned request since the call was added
in commit
1ebf561; qcow2_co_pdiscard() has passed a cluster-aligned
request since commit
ecdbead taught the block layer about preferred
discard alignment; and qcow2_make_empty() was fixed to pass an
aligned start (but not necessarily end) in commit
a3e1505.
Asserting that the start is always aligned also points out that we
now have a dead check: rounding the end offset down can never result
in a value less than the aligned start offset (the check was rendered
dead with commit
ecdbead). Meanwhile, we do not want to round the
end cluster down in the one case of the end offset matching the
(unaligned) file size - that final partial cluster should still be
discarded.
With those fixes in place, the fast and slow paths are back in sync
at discarding an entire image; the next patch will update
qemu-iotests to ensure we don't regress.
Note that bdrv_co_pdiscard ignores ALL partial cluster requests,
including the partial cluster at the end of an image; it can be
argued that the partial cluster at the end should be special-cased
so that a guest issuing discard requests at proper alignments
everywhere else can likewise empty the entire image. But that
optimization is left for another day.

qcow (v1) does not support internal snapshots, so this change

nbd: Tidy up blockdev-add interface
SocketAddress is a simple union, and simple unions are awkward: they
have their variant members wrapped in a "data" object on the wire, and
require additional indirections in C. I intend to limit its use to
existing external interfaces, and convert all internal interfaces to
SocketAddressFlat.
BlockdevOptionsNbd is an external interface using SocketAddress. We
already use SocketAddressFlat elsewhere in blockdev-add. Replace it
by SocketAddressFlat while we can (it's new in 2.9) for simplicity and
consistency. For example,
{ "execute": "blockdev-add",
"arguments": { "node-name": "foo", "driver": "nbd",
"server": { "type": "inet",
"data": { "host": "localhost",
"port": "12345" } } } }
becomes
{ "execute": "blockdev-add",
"arguments": { "node-name": "foo", "driver": "nbd",
"server": { "type": "inet",
"host": "localhost", "port": "12345" } } }
Since the internal interfaces still take SocketAddress, this requires
conversion function socket_address_crumple(). It'll go away when I
update the interfaces.
Unfortunately, SocketAddress is also visible in -drive since 2.8:
-drive if=none,driver=nbd,server.type=inet,server.data.host=127.0.0.1,server.data.port=12345
Nobody should be using it, as it's fairly new and has never been
documented, so adding still more compatibility gunk to keep it working
isn't worth the trouble. You now have to use
-drive if=none,driver=nbd,server.type=inet,server.host=127.0.0.1,server.port=12345

[mreitz: Change iotest 147 accordingly]
Because of this interface change, iotest 147 has to be adapted.
Unfortunately, we cannot just flatten all of the addresses because
nbd-server-start still takes a plain SocketAddress. Therefore, we need
both and this is most easily achieved by writing the SocketAddress into
the code and flattening it where necessary.

block: Document -drive problematic code and bugs
-blockdev and blockdev_add convert their arguments via QObject to
BlockdevOptions for qmp_blockdev_add(), which converts them back to
QObject, then to a flattened QDict. The QDict's members are typed
according to the QAPI schema.
-drive converts its argument via QemuOpts to a (flat) QDict. This
QDict's members are all QString.
Thus, the QType of a flat QDict member depends on whether it comes
from -drive or -blockdev/blockdev_add, except when the QAPI type maps
to QString, which is the case for 'str' and enumeration types.
The block layer core extracts generic configuration from the flat
QDict, and the block driver extracts driver-specific configuration.
Both commonly do so by converting (parts of) the flat QDict to
QemuOpts, which turns all values into strings. Not exactly elegant,
but correct.
However, A few places access the flat QDict directly:
* Most of them access members that are always QString. Correct.
* bdrv_open_inherit() accesses a boolean, carefully. Correct.
* nfs_config() uses a QObject input visitor. Correct only because the
visited type contains nothing but QStrings.
* nbd_config() and ssh_config() use a QObject input visitor, and the
visited types contain non-QStrings: InetSocketAddress members
@numeric, @to, @ipv4, @ipv6. -drive works as long as you don't try
to use them (they're all optional). @to is ignored anyway.
Reproducer:
-drive driver=ssh,server.host=h,server.port=22,server.ipv4,path=p
-drive driver=nbd,server.type=inet,server.data.host=h,server.data.port=22,server.data.ipv4
both fail with "Invalid parameter type for 'data.ipv4', expected: boolean"
Add suitable comments to all these places. Mark the buggy ones FIXME.
"Fortunately", -drive's driver-specific options are entirely
undocumented.

rbd: Fix regression in legacy key/values containing escaped :
Commit
c7cacb3 accidentally broke legacy key-value parsing through
pseudo-filename parsing of -drive file=rbd://..., for any key that
contains an escaped ':'. Such a key is surprisingly common, thanks
to mon_host specifying a 'host:port' string. The break happens
because passing things from QDict through QemuOpts back to another
QDict requires that we pack our parsed key/value pairs into a string,
and then reparse that string, but the intermediate string that we
created ("key1=value1:key2=value2") lost the \: escaping that was
present in the original, so that we could no longer see which : were
used as separators vs. those used as part of the original input.
Fix it by collecting the key/value pairs through a QList, and
sending that list on a round trip through a JSON QString (as in
'["key1","value1","key2","value2"]') on its way through QemuOpts,
rather than hand-rolling our own string. Since the string is only
handled internally, this was faster than creating a full-blown
struct of '[{"key1":"value1"},{"key2":"value2"}]', and safer at
guaranteeing order compared to '{"key1":"value1","key2":"value2"}'.
It would be nicer if we didn't have to round-trip through QemuOpts
in the first place, but that's a much bigger task for later.
Reproducer:
./x86_64-softmmu/qemu-system-x86_64 -nodefaults -nographic -qmp stdio \
-drive 'file=rbd:volumes/volume-
ea141b5c-cdb3-4765-910d-
e7008b209a70'\
':id=compute:key=AQAVkvxXAAAAABAA9ZxWFYdRmV+DSwKr7BKKXg=='\
':auth_supported=cephx\;none:mon_host=192.168.1.2\:6789'\

'serial=
ea141b5c-cdb3-4765-910d-
e7008b209a70,cache=writeback'
Even without an RBD setup, this serves a test of whether we get
the incorrect parser error of:
qemu-system-x86_64: -drive file=rbd:...cache=writeback: conf option 6789 has no value
or the correct behavior of hanging while trying to connect to
the requested mon_host of 192.168.1.2:6789.

qga: don't fail if mount doesn't have slave devices
In some cases the slave devices of a virtual block device are tracked
by the parent in the corresponding sysfs node. For instance, if we
have a loop-back mount of the form:
/dev/loop3p1 on /home/mdroth/mnt type ext4 (rw,relatime,data=ordered)
this will be reflected in sysfs as:
/sys/devices/virtual/block/loop3/
...
/sys/devices/virtual/block/loop3/slaves
/sys/devices/virtual/block/loop3/loop3p1
The current code however assumes the mounted virtual block device,
loop3p1 in this case, contains the slaves directory, and reports an
error otherwise. This breaks 'make check' in certain environments.
Fix this by simply skipping attempts to generate disk topology
information in these cases. Since this information is documented
in QAPI as optionally-reported, this should be ok from an API
perspective.
In the future, this can possibly be improved upon by collecting
topology information from the parent in these cases.

vhost: generalize iommu memory region
We assumes the iommu_ops were attached to the root region of address
space. This may not be true for all kinds of IOMMU implementation and
especially after commit
3716d5902d74 ("pci: introduce a bus master
container"). So fix this by not assuming as->root has iommu_ops,
instead depending on the regions reported by memory listener through:
- register a memory listener to dma_as
- during region_add, if it's a region of IOMMU, register a specific
IOMMU notifier, and store all notifiers in a list.
- during region_del, compare and delete the IOMMU notifier from the list
This is also a must for making vhost device IOTLB works for all types
of IOMMUs. Note, since we register one notifier during each
.region_add, the IOTLB may be flushed more than one times, this is
suboptimal and could be optimized in the future.

configure: Don't claim 'unsupported host OS' when better message available
The change in commit
898be3e0415c6d which made completely
unrecognized OSes cause an error_exit "Unsupported host OS"
has some unfortunate unintended effects:
* if you run 'configure --help' on an unsupported host OS
(eg if intending to use it as a build machine for a
cross compile to a supported host) then the message
is printed instead of --help
* if the C compiler doesn't work or is missing (eg if
you passed an incorrect --cross-prefix by mistake)
the message is printed instead of the more useful
'compiler does not exist or does not work' message
Fix this by postponing the error_exit in this situation
until later, when we have already identified the more
useful cases for this.
The long term fix for this would be to move handling
of --help much further up in the configure script,
and make its output not dependent on checks that configure
runs. However for 2.9 this would be too invasive.

If we take a closer look to the guest kernel log, we can see when
we try to unplug the memory:
pseries-hotplug-mem: Attempting to hot-add 4 LMB(s)
What happens:
1- The kernel has ignored the memory hotplug event because
it was not started when it was generated.
2- When we hot-unplug the memory,
QEMU starts to remove the memory,
generates an hot-unplug event,
and signals the kernel of the incoming new event
3- as the kernel is started, on the QEMU signal, it reads
the event list, decodes the hotplug event and tries to
finish the hotplugging.
4- QEMU receive the the hotplug notification while it
is trying to hot-unplug the memory. This moves the memory
DRC to an invalid state
This patch prevents this by not allowing to set the allocation
state to USABLE while the DRC is awaiting release.

i386: Don't override -cpu options on -cpu host/max
The existing code for "host" and "max" CPU models overrides every
single feature in the CPU object at realize time, even the ones
that were explicitly enabled or disabled by the user using
"feat=on" or "feat=off", while features set using +feat/-feat are
kept.
This means "-cpu host,+invtsc" works as expected, while
"-cpu host,invtsc=on" doesn't.
This was a known bug, already documented in a comment inside
x86_cpu_expand_features(). What makes this bug worse now is that
libvirt 3.0.0 and newer now use "feat=on|off" instead of
+feat/-feat when it detects a QEMU version that supports it (see
libvirt commit
d47db7b16dd5422c7e487c8c8ee5b181a2f9cd66).
Change the feature property getter/setter to set a
env->user_features field, to keep track of features that were
explicitly changed using QOM properties. Then make the
max_features code not override user features when handling "-cpu
host" and "-cpu max".
This will also allow us to remove the plus_features/minus_features
hack in the future, but I plan to do that after 2.9.0 is
released.

sockets: Fix socket_address_to_string() hostname truncation
We first snprintf() to a fixed buffer, then g_strdup() the result
*boggle*.
Worse, the size of the fixed buffer INET6_ADDRSTRLEN + 5 + 4 is bogus:
the 4 correctly accounts for '[', ']', ':' and '\0', but
INET6_ADDRSTRLEN is not a suitable limit for inet->host, and 5 is not
one for inet->port! They are for host and port in *numeric* form
(exploiting that INET6_ADDRSTRLEN > INET_ADDRSTRLEN), but inet->host
can also be a hostname, and inet->port can be a service name, to be
resolved with getaddrinfo().
Fortunately, the only user so far is the "socket" network backend's
net_socket_connected(), which uses it to initialize a NetSocketState's
info_str[]. info_str[] has considerable more space: 256 instead of
55. So the bug's impact appears to be limited to truncated "info
networks" with the "socket" network backend.
The fix is obvious: use g_strdup_printf().

rbd: Fix bugs around -drive parameter "server"
qemu_rbd_open() takes option parameters as a flattened QDict, with
keys of the form server.%d.host, server.%d.port, where %d counts up
from zero.
qemu_rbd_array_opts() extracts these values as follows. First, it
calls qdict_array_entries() to find the list's length. For each list
element, it formats the list's key prefix (e.g. "server.0."), then
creates a new QDict holding the options with that key prefix, then
converts that to a QemuOpts, so it can finally get the member values
from there.
If there's one surefire way to make code using QDict more awkward,
it's creating more of them and mixing in QemuOpts for good measure.
The extraction of keys starting with server.%d into another QDict
makes us ignore parameters like server.0.neither-host-nor-port
silently.
The conversion to QemuOpts abuses runtime_opts, as described a few
commits ago.
Rewrite to simply get the values straight from the options QDict.
Fixes -drive not to crash when server.*.* are present, but
server.*.host is absent.
Fixes -drive to reject invalid server.*.*.
Permits cleaning up runtime_opts. Do that, and fix -drive to reject
bogus parameters host and port instead of silently ignoring them.

rbd: Revert -blockdev and -drive parameter auth-supported
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.

rbd: Clean up runtime_opts, fix -drive to reject filename
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.

rbd: Don't limit length of parameter values
We laboriously enforce that parameter values are between one and some
arbitrary limit in length. Only RBD_MAX_IMAGE_NAME_SIZE comes from
librbd.h, and I'm not sure it applies. Where the other limits come
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
a dynamically allocated string.

rbd: Fix to cleanly reject -drive without pool or image
qemu_rbd_open() neglects to check pool and image are present. Missing
image is caught by rbd_open(), but missing pool crashes. Reproducer:
$ qemu-system-x86_64 -nodefaults -drive driver=rbd,id=rbd,image=i,...
terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_M_construct null not valid
Aborted (core dumped)
where ... is a working server.0.{host,port} configuration.
Doesn't affect -drive with file=..., because qemu_rbd_parse_filename()
always sets both pool and image.
Doesn't affect -blockdev, because pool and image are mandatory in the
QAPI schema.
Fix by adding the missing checks.

rbd: Reject -blockdev server.*.{numeric, to, ipv4, ipv6}
We use InetSocketAddress in the QAPI schema. However, the code
doesn't use inet_connect_saddr(), but formats "host" and "port" into a
configuration string for rados_conf_set(). Thus, members "numeric",
"to", "ipv4" and "ipv6" are silently ignored. Not nice. Example:
-blockdev rbd,node-name=nn,pool=p,image=i,server.0.host=h0,server.0.port=12345,server.0.ipv4=off
Factor a suitable InetSocketAddressBase out of InetSocketAddress, and
use that. "numeric", "to", "ipv4" and "ipv6" are now rejected.

block: Declare blockdev-add and blockdev-del supported
It's been a long journey, but here we are.
The supported blockdev-add is not compatible to its experimental

x-blockdev-remove-medium, x-blockdev-insert-medium and
x-blockdev-change need a bit more work, so leave them alone for now.
