ca86608f7b qga/qapi-schema: Plug trivial documentation holes
Add missing return member documentation of guest-get-disks,
guest-get-devices, guest-get-diskstats, and guest-get-cpustats.

The NVMe SMART information returned by guest-getdisks remains
undocumented.  Add a TODO there.

0cec50119f qapi: Require member documentation (with loophole)
The QAPI generator forces you to document your stuff.  Except for
command arguments, event data, and members of enum and object types:
these the generator silently "documents" as "Not documented".

We can't require proper documentation there without first fixing all
the offenders.  We've always had too many offenders to pull that off.
Right now, we have more than 500.  Worse, we seem to fix old ones no
faster than we add new ones: in the past year, we fixed 22 ones, but
added 26 new ones.

To help arrest the backsliding, make missing documentation an error
unless the command, type, or event is in listed in new pragma
documentation-exceptions.

List all the current offenders: 117 commands and types in qapi/, and 9
in qga/.

fd62bff901 sphinx/qapidoc: Drop code to generate doc for simple union tag
QAPISchemaGenRSTVisitor._nodes_for_members() has a special case to
auto-generate documentation for a union tag member of implicit (enum)
type that lacks documentation.

This was useful for simple unions, where the tag member's type was
implicitly.  The only implicit enum type left today is 'QType'.  Not
worth a special case.  Drop.  No change to generated documentation.

d988487882 qapi/block-core: Fix BlockLatencyHistogramInfo doc markup
The description of @bins ends with a literal block:

    # @bins: list of io request counts corresponding to histogram
    #     intervals, one more element than @boundaries has.  For the
    #     example above, @bins may be something like [3, 1, 5, 2], and
    #     corresponding histogram looks like:
    #
    # ::
    #
    #        5|           *

Except it actually ends *before* the block: the unindented '::' line
starts a new section.  Makes no sense.

We could fix this by indenting the '::' line.  Instead, double the
colon at the end of the preceding paragraph, and drop the '::' line.

This shifts the box for the literal block right in generated
documentation, so it lines up with the description.

Fixes: commit a0fcff383b (qapi: Use rST markup for literal blocks)

9b60a3ed55 hw/net/tulip: add chip status register values
Netbsd isn't able to detect a link on the emulated tulip card. That's
because netbsd reads the Chip Status Register of the Phy (address
0x14). The default phy data in the qemu tulip driver is all zero,
which means no link is established and autonegotation isn't complete.

Therefore set the register to 0x3b40, which means:

Link is up, Autonegotation complete, Full Duplex, 100MBit/s Link
speed.

Also clear the mask because this register is read only.

HP-UX 11 and HP ODE tools use the "rsm 0,%reg" instruction in not priviledged
code paths to get the current PSW flags. The constant 0 means that no bits of

f410b688af hw/pci-host/astro: Implement Hard Fail and Soft Fail mode
The Astro/Elroy chip can work in either Hard-Fail or Soft-Fail mode.

Hard fail means the system bus will send an HPMC (=crash) to the
processor, soft fail means the system bus will ignore timeouts of
MMIO-reads or MMIO-writes and return -1ULL.

The HF mode is controlled by a bit in the status register and is usually
programmed by the OS. Return the corresponing values based on the current
value of that bit.

dbca083513 target/hppa: Add "diag 0x101" for console output support
For debugging purposes at the early stage of the bootup process,
the SeaBIOS-hppa firmware sometimes needs to output characters to the
serial console. Note that the serial console is the default output
method for parisc machines.

At this stage PCI busses and other devices haven't been initialized
yet. So, SeaBIOS-hppa will not be able to find the correct I/O ports
for the serial ports yet.

Instead, add an emulation for the "diag 0x101" opcode to assist here.
Without any other dependencies, SeaBIOS-hppa can then load the character
to be printed in register %r26 and issue the diag assembly instruction.

The qemu diag_console_output() helper function will then print
that character to the first serial port.

35286daeca block: Support detached LUKS header creation using qemu-img
Even though a LUKS header might be created with cryptsetup,
qemu-img should be enhanced to accommodate it as well.

Add the 'detached-header' option to specify the creation of
a detached LUKS header. This is how it is used:
$ qemu-img create --object secret,id=sec0,data=abc123 -f luks
> -o cipher-alg=aes-256,cipher-mode=xts -o key-secret=sec0
> -o detached-header=true header.luks

Using qemu-img or cryptsetup tools to query information of
an LUKS header image as follows:

Assume a detached LUKS header image has been created by:
$ dd if=/dev/zero of=test-header.img bs=1M count=32
$ dd if=/dev/zero of=test-payload.img bs=1M count=1000
$ cryptsetup luksFormat --header test-header.img test-payload.img
> --force-password --type luks1

Header image information could be queried using cryptsetup:
$ cryptsetup luksDump test-header.img

or qemu-img:
$ qemu-img info 'json:{"driver":"luks","file":{"filename":
> "test-payload.img"},"header":{"filename":"test-header.img"}}'

When using qemu-img, keep in mind that the entire disk
information specified by the JSON-format string above must be
supplied on the commandline; if not, an overlay check will reveal
a problem with the LUKS volume check logic.

d0112eb415 block: Support detached LUKS header creation using blockdev-create
Firstly, enable the ability to choose the block device containing
a detachable LUKS header by adding the 'header' parameter to
BlockdevCreateOptionsLUKS.

Secondly, when formatting the LUKS volume with a detachable header,
truncate the payload volume to length without a header size.

Using the qmp blockdev command, create the LUKS volume with a
detachable header as follows:

1. add the secret to lock/unlock the cipher stored in the
   detached LUKS header
$ virsh qemu-monitor-command vm '{"execute":"object-add",
> "arguments":{"qom-type": "secret", "id": "sec0", "data": "foo"}}'

2. create a header img with 0 size
$ virsh qemu-monitor-command vm '{"execute":"blockdev-create",
> "arguments":{"job-id":"job0", "options":{"driver":"file",
> "filename":"/path/to/detached_luks_header.img", "size":0 }}}'

3. add protocol blockdev node for header
$ virsh qemu-monitor-command vm '{"execute":"blockdev-add",
> "arguments": {"driver":"file", "filename":
> "/path/to/detached_luks_header.img", "node-name":
> "detached-luks-header-storage"}}'

4. create a payload img with 0 size
$ virsh qemu-monitor-command vm '{"execute":"blockdev-create",
> "arguments":{"job-id":"job1", "options":{"driver":"file",
> "filename":"/path/to/detached_luks_payload_raw.img", "size":0}}}'

5. add protocol blockdev node for payload
$ virsh qemu-monitor-command vm '{"execute":"blockdev-add",
> "arguments": {"driver":"file", "filename":
> "/path/to/detached_luks_payload_raw.img", "node-name":
> "luks-payload-raw-storage"}}'

6. do the formatting with 128M size
$ virsh qemu-monitor-command c81_node1 '{"execute":"blockdev-create",
> "arguments":{"job-id":"job2", "options":{"driver":"luks", "header":
> "detached-luks-header-storage", "file":"luks-payload-raw-storage",

9ad5c4e7ee crypto: Support LUKS volume with detached header
By enhancing the LUKS driver, it is possible to implement
the LUKS volume with a detached header.

Normally a LUKS volume has a layout:
  disk:  | header | key material | disk payload data |

With a detached LUKS header, you need 2 disks so getting:
  disk1:  | header | key material |
  disk2:  | disk payload data |

There are a variety of benefits to doing this:
 * Secrecy - the disk2 cannot be identified as containing LUKS
             volume since there's no header
 * Control - if access to the disk1 is restricted, then even
             if someone has access to disk2 they can't unlock
             it. Might be useful if you have disks on NFS but
             want to restrict which host can launch a VM
             instance from it, by dynamically providing access
             to the header to a designated host
 * Flexibility - your application data volume may be a given
                 size and it is inconvenient to resize it to
                 add encryption.You can store the LUKS header
                 separately and use the existing storage
                 volume for payload
 * Recovery - corruption of a bit in the header may make the
              entire payload inaccessible. It might be
              convenient to take backups of the header. If
              your primary disk header becomes corrupt, you
              can unlock the data still by pointing to the
              backup detached header

Take the raw-format image as an example to introduce the usage
of the LUKS volume with a detached header:

1. prepare detached LUKS header images
$ dd if=/dev/zero of=test-header.img bs=1M count=32
$ dd if=/dev/zero of=test-payload.img bs=1M count=1000
$ cryptsetup luksFormat --header test-header.img test-payload.img
> --force-password --type luks1

2. block-add a protocol blockdev node of payload image
$ virsh qemu-monitor-command vm '{"execute":"blockdev-add",
> "arguments":{"node-name":"libvirt-1-storage", "driver":"file",
> "filename":"test-payload.img"}}'

3. block-add a protocol blockdev node of LUKS header as above.
$ virsh qemu-monitor-command vm '{"execute":"blockdev-add",
> "arguments":{"node-name":"libvirt-2-storage", "driver":"file",
> "filename": "test-header.img" }}'

4. object-add the secret for decrypting the cipher stored in
   LUKS header above
$ virsh qemu-monitor-command vm '{"execute":"object-add",
> "arguments":{"qom-type":"secret", "id":
> "libvirt-2-storage-secret0", "data":"abc123"}}'

5. block-add the raw-drived blockdev format node
$ virsh qemu-monitor-command vm '{"execute":"blockdev-add",
> "arguments":{"node-name":"libvirt-1-format", "driver":"raw",
> "file":"libvirt-1-storage"}}'

6. block-add the luks-drived blockdev to link the raw disk
   with the LUKS header by specifying the field "header"
$ virsh qemu-monitor-command vm '{"execute":"blockdev-add",
> "arguments":{"node-name":"libvirt-2-format", "driver":"luks",
> "file":"libvirt-1-format", "header":"libvirt-2-storage",
> "key-secret":"libvirt-2-format-secret0"}}'

7. hot-plug the virtio-blk device finally
$ virsh qemu-monitor-command vm '{"execute":"device_add",
> "arguments": {"num-queues":"1", "driver":"virtio-blk-pci",
> "drive": "libvirt-2-format", "id":"virtio-disk2"}}'

Starting a VM with a LUKS volume with detached header is
somewhat similar to hot-plug in that both maintaining the
same json command while the starting VM changes the
"blockdev-add/device_add" parameters to "blockdev/device".

cb8ded0f6d chardev: close QIOChannel before unref'ing
The chardev socket backend will unref the QIOChannel object while
it is still potentially open. When using TLS there could be a
pending TLS handshake taking place. If the channel is left open
then when the TLS handshake callback runs, it can end up accessing
free'd memory in the tcp_chr_tls_handshake method.

Closing the QIOChannel will unregister any pending handshake
source.

0e74eb86ea ui: drop VNC feature _MASK constants
Each VNC feature enum entry has a corresponding _MASK constant
which is the bit-shifted value. It is very easy for contributors
to accidentally use the _MASK constant, instead of the non-_MASK
constant, or the reverse. No compiler warning is possible and
it'll just silently do the wrong thing at runtime.

By introducing the vnc_set_feature helper method, we can drop
all the _MASK constants and thus prevent any future accidents.

03e471c41d qemu_init: increase NOFILE soft limit on POSIX
In many configurations, e.g. multiple vNICs with multiple queues or
with many Ceph OSDs, the default soft limit of 1024 is not enough.
QEMU is supposed to work fine with file descriptors >= 1024 and does
not use select() on POSIX. Bump the soft limit to the allowed hard
limit to avoid issues with the aforementioned configurations.

Of course the limit could be raised from the outside, but the man page
of systemd.exec states about 'LimitNOFILE=':

> Don't use.
> [...]
> Typically applications should increase their soft limit to the hard
> limit on their own, if they are OK with working with file
> descriptors above 1023,

If the soft limit is already the same as the hard limit, avoid the
superfluous setrlimit call. This can avoid a warning with a strict
seccomp filter blocking setrlimit if NOFILE was already raised before
executing QEMU.

deb0ff0c77 target/riscv: add rv32i, rv32e and rv64e CPUs
A bare bones 32 bit RVI CPU, rv32i, will make users lives easier when a
full customized 32 bit CPU is desired, and users won't need to disable
defaults by hand as they would with the rv32 CPU. [1] has an example of
a situation that would be avoided with rv32i.

In fact, add bare bones CPUs for RVE as well. Trying to use RVE in QEMU
requires one to disable every single default extension, including RVI,
and then add the desirable extension set. Adding rv32e/rv64e makes it
more pleasant to use embedded CPUs in QEMU.
