the same AHB Peripheral Protection Controller that handles

in the block diagram but the ethernet controller was omitted
from the table listing devices connected to the PPC.)

Legacy -drive supports "password-secret" parameter that isn't

Addressed by the rename.

Parameter auth-client-required lets you configure authentication
methods. We tried to provide that in v2.9.0, but backed out due to
interface design doubts (commit 464444fcc1).
This commit is similar to what we backed out, but simpler: we use a
list of enumeration values instead of a list of objects with a member
of enumeration type.
Let's review our reasons for backing out the first try, as stated in
the commit message:
* The implementation uses deprecated rados_conf_set() key
"auth_supported". No biggie.
Fixed: we use "auth-client-required".
* 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.
That fix is commit 2836284db6. This commit doesn't bring the bugs
back.
* BlockdevOptionsRbd member @password-secret applies only to
authentication method cephx. Should it be a variant member of
RbdAuthMethod?
We've had time to ponder, and we decided to stick to the way Ceph
configuration works: the key configured separately, and silently
ignored if the authentication method doesn't use it.
* 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?
Likewise.
* 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.
Again, we decided to stick to the way Ceph configuration works, except
we make auth-client-required a list of enumeration values instead of a
string containing keywords separated by delimiters.
* How BlockdevOptionsRbd member @auth-supported interacts with
settings from a configuration file specified with @conf is
undocumented. I suspect it's untested, too.
Not actually true, the documentation for @conf says "Values in the

-blockdev and blockdev-add silently ignore empty objects and arrays in
their argument. That's because qmp_blockdev_add() converts the
argument to a flat QDict, and qdict_flatten() eats empty QDict and
QList members. For instance, we ignore an empty BlockdevOptions
member @cache. No real harm, as absent means the same as empty there.
Thus, the flaw puts an artificial restriction on the QAPI schema: we
can't have potentially empty objects and arrays within
BlockdevOptions, except when they're optional and "empty" has the same
meaning as "absent".
Our QAPI schema satisfies this restriction (I checked), but it's a
trap for the unwary, and a temptation to employ awkward workarounds
for the wary. Let's get rid of it.

Configuration flows through the block subsystem in a rather peculiar
way. Configuration made with -drive enters it as QemuOpts.
Configuration made with -blockdev / blockdev-add enters it as QAPI
type BlockdevOptions. The block subsystem uses QDict, QemuOpts and
QAPI types internally. The precise flow is next to impossible to
explain (I tried for this commit message, but gave up after wasting
several hours). What I can explain is a flaw in the BlockDriver
interface that leads to this bug:
$ qemu-system-x86_64 -blockdev node-name=n1,driver=nfs,server.type=inet,server.host=localhost,path=/foo/bar,user=1234
qemu-system-x86_64: -blockdev node-name=n1,driver=nfs,server.type=inet,server.host=localhost,path=/foo/bar,user=1234: Internal error: parameter user invalid
QMP blockdev-add is broken the same way.
Here's what happens. The block layer passes configuration represented
as flat QDict (with dotted keys) to BlockDriver methods
.bdrv_file_open(). The QDict's members are typed according to the
QAPI schema.
nfs_file_open() converts it to QAPI type BlockdevOptionsNfs, with
qdict_crumple() and a qobject input visitor.
This visitor comes in two flavors. The plain flavor requires scalars
to be typed according to the QAPI schema. That's the case here. The
keyval flavor requires string scalars. That's not the case here.
nfs_file_open() uses the latter, and promptly falls apart for members
@user, @group, @tcp-syn-count, @readahead-size, @page-cache-size,
@debug.
Switching to the plain flavor would fix -blockdev, but break -drive,
because there the scalars arrive in nfs_file_open() as strings.
The proper fix would be to replace the QDict by QAPI type
BlockdevOptions in the BlockDriver interface. Sadly, that's beyond my
reach right now.
Next best would be to fix the block layer to always pass correctly
typed QDicts to the BlockDriver methods. Also beyond my reach.
What I can do is throw another hack onto the pile: have
nfs_file_open() convert all members to string, so use of the keyval
flavor actually works, by replacing qdict_crumple() by new function
qdict_crumple_for_keyval_qiv().
The pattern "pass result of qdict_crumple() to
qobject_input_visitor_new_keyval()" occurs several times more:
* qemu_rbd_open()
Same issue as nfs_file_open(), but since BlockdevOptionsRbd has only
string members, its only a latent bug. Fix it anyway.
* parallels_co_create_opts(), qcow_co_create_opts(),
qcow2_co_create_opts(), bdrv_qed_co_create_opts(),
sd_co_create_opts(), vhdx_co_create_opts(), vpc_co_create_opts()
These work, because they create the QDict with
qemu_opts_to_qdict_filtered(), which creates only string scalars.
The function sports a TODO comment asking for better typing; that's
going to be fun. Use qdict_crumple_for_keyval_qiv() to be safe.

Commit a290f085 exposed a latent bug in qemu-img map introduced
during the conversion of block status to be byte-based. Earlier in
commit 5e344dd8, the internal interface get_block_status() switched
to take byte-based parameters, but still called a sector-based
block layer function; as such, rounding was added in the lone
caller to obey the contract. However, commit 237d78f8 changed
get_block_status() to truly be byte-based, at which point rounding
to sector boundaries can result in calling bdrv_block_status() with
'bytes == 0' (a coding error) when the boundary between data and a
hole falls mid-sector (true for the past-EOF implicit hole present
in POSIX files). Fix things by removing the rounding that is now
no longer necessary.

As qemu_new_net_client create new ncs but error happens later,
ncs will be left in global net_clients list and we can't use them any
more, so we need to cleanup them.

The spec does not justify clearing of any E1000_ICR_OTHER_CAUSES when
E1000_ICR_OTHER is set in EIAC. In fact, removing this code fixes the
issue the Linux driver runs into since 4aea7a5c5e94 ("e1000e: Avoid
receiver overrun interrupt bursts") and was worked around by
745d0bd3af99 ("e1000e: Remove Other from EIAC").

If user forgets to provide any backend types for '-netdev' in qemu CLI,
It triggers seg fault.
e.g.
Expected:
$ qemu -netdev id=net0
qemu-system-x86_64: Parameter 'type' is missing
Actual:
$ qemu -netdev id=net0
Segmentation fault (core dumped)

A guest boot hangs while probing the network interface when
iommu_platform=on is used.
The following qemu cli hangs without this patch:
# $QEMU \
-netdev tap,fd=3,id=hostnet0,vhost=on,vhostfd=4 3<>/dev/tap67 4<>/dev/host-net \
-device virtio-net-pci,netdev=hostnet0,id=net0,iommu_platform=on,disable-legacy=on \
...
Commit: c471ad0e9b (vhost_net: device IOTLB support) took care of
setting vhostfd to non-blocking when QEMU opens /dev/host-net but if
the fd is passed from qemu cli then we need to ensure that fd is set
to non-blocking.
