migration/rdma: Send error during cancelling

When we issue a cancel and clean up the RDMA channel
send a CONTROL_ERROR to get the destination to quit.

The rdma_cleanup code waits for the event to come back

destination quits and there's currently nothing to force

It may not always be possible, as in the existing case when a filesize

7 years agolive-block-ops.txt: Rename, rewrite, and improve it
Kashyap Chamarthy [Mon, 17 Jul 2017 10:52:05 +0000 (12:52 +0200)] 
live-block-ops.txt: Rename, rewrite, and improve it

This patch documents (including their QMP invocations) all the four
major kinds of live block operations:

  - `block-stream`
  - `block-commit`
  - `drive-mirror` (& `blockdev-mirror`)
  - `drive-backup` (& `blockdev-backup`)

Things considered while writing this document:

  - Use reStructuredText as markup language (with the goal of generating
    the HTML output using the Sphinx Documentation Generator).  It is
    gentler on the eye, and can be trivially converted to different
    formats.  (Another reason: upstream QEMU is considering to switch to
    Sphinx, which uses reStructuredText as its markup language.)

  - Raw QMP JSON output vs. 'qmp-shell'.  I debated with myself whether
    to only show raw QMP JSON output (as that is the canonical
    representation), or use 'qmp-shell', which takes key-value pairs.  I
    settled on the approach of: for the first occurrence of a command,
    use raw JSON; for subsequent occurrences, use 'qmp-shell', with an
    occasional exception.

  - Usage of `-blockdev` command-line.

  - Usage of 'node-name' vs. file path to refer to disks.  While we have
    `blockdev-{mirror, backup}` as 'node-name'-alternatives for
    `drive-{mirror, backup}`, the `block-commit` command still operates
    on file names for parameters 'base' and 'top'.  So I added a caveat
    at the beginning to that effect.

    Refer this related thread that I started (where I learnt
    `block-stream` was recently reworked to accept 'node-name' for 'top'
    and 'base' parameters):
    https://lists.nongnu.org/archive/html/qemu-devel/2017-05/msg06466.html
    "[RFC] Making 'block-stream', and 'block-commit' accept node-name"

All commands showed in this document were tested while documenting.

Thanks: Eric Blake for the section: "A note on points-in-time vs file
names".  This useful bit was originally articulated by Eric in his
KVMForum 2015 presentation, so I included that specific bit in this
document.

nbd: Fix server reply to NBD_OPT_EXPORT_NAME of older clients

A typo in commit 23e099c set the size of buf[] used in response
to NBD_OPT_EXPORT_NAME according to the length needed for old-style
negotiation (4 bytes of flag information) instead of the intended
2 bytes used in new style.  If the client doesn't enable
NBD_FLAG_C_NO_ZEROES, then the server sends two bytes too many,
and is then out of sync in response to the client's next command
(the bug is masked when modern qemu is the client, since we enable
the no zeroes flag).

While touching this code, add some more defines to nbd_internal.h
rather than having quite so many magic numbers in the .c; also,
use "" initialization rather than memset(), and tweak the oldstyle
negotiation to better match the spec description of the layout
(since the spec is big-endian, skipping two bytes as 0 followed by
writing a 2-byte flag is the same as writing a zero-extended 4-byte
flag), to make it a bit easier to follow compared to the spec.

    when a segment-table entry or entries are
    invalidated. IDTE also performs the clearing-by-
    ASCE operation. Unless bit 4 is one, IDTE simply
    purges all TLBs. Bit 3 is one if bit 4 is one.

We can simply set STFL bit 4 ("idtes") and still purge the complete TLB.
Purging more than advertised is never bad. E.g. Linux doesn't even care
about this bit. We can optimized this later.
This is helpful, as the z9 base model contains this facility.

STFL bit 5 (clearing TLB region-table-entries) was never implemented on
real HW, therefore we can simply ignore it for now.

the export is not present, breaking a couple of iotests.  The error
message is now directly given by the server (a failed NBD_OPT_GO)

reword the error message to be slightly less verbose (as this is
one particular error message likely to be hit by a user).

Note that the error message is now sensitive to which binary is
running the server as well as the client (since the expected
output is replaying a message received from the server - for that
matter, it depends on a server new enough to understand NBD_OPT_GO);
in general iotests are run on client and server from the same source
code base so the default setup will pass; but if it proves
problematic for people overriding QEMU_PROG, QEMU_IMG_PROG,
QEMU_IO_PROG, and QEMU_NBD_PROG to point across multiple builds for

HyperV, Xen, BHyve) all do the same thing, which leaves
TCG as the odd one out.

The CPUID signature is used by software to detect which
virtual environment they are running in and (potentially)
change behaviour in certain ways. For example, systemd
supports a ConditionVirtualization= setting in unit files.
The virt-what command can also report the virt type it is
running on

Currently both these apps have to resort to custom hacks
like looking for 'fw-cfg' entry in the /proc/device-tree
file to identify TCG.

This change thus proposes a signature "TCGTCGTCGTCG" to be

qdev: fix the order compat and global properties are applied

The current code recursively applies global properties from child up to
parent types. This can cause properties passed with the -global option to
be silently overridden by internal compat properties.

This is exactly what happened with virtio-*-pci drivers since commit:

"9a4c0e220d8a hw/virtio-pci: fix virtio behaviour"

Passing -device virtio-blk-pci.disable-modern=off had no effect on 2.6
machine types because the internal virtio-pci.disable-modern=on compat
property always prevailed.

A workaround for this was included with commit 0bcba41f ("machine:
Convert abstract typename on compat_props to subclass names").

This patch fixes the issue properly by reversing the logic: we now go
through the global property list and, for each property, we check if it
is applicable to the device.

This results in compat properties being applied first, in the order they
appear in the HW_COMPAT_* macros, followed by global properties, in the
order they appear on the command line.

vfio-pci, ppc64/spapr: Reorder group-to-container attaching

At the moment VFIO PCI device initialization works as follows:
vfio_realize
vfio_get_group
vfio_connect_container
register memory listeners (1)
update QEMU groups lists
vfio_kvm_device_add_group

Then (example for pseries) the machine reset hook triggers region_add()
for all regions where listeners from (1) are listening:

ppc_spapr_reset
spapr_phb_reset
spapr_tce_table_enable
memory_region_add_subregion
vfio_listener_region_add
vfio_spapr_create_window

This scheme works fine until we need to handle VFIO PCI device hotplug
and we want to enable PPC64/sPAPR in-kernel TCE acceleration on,
i.e. after PCI hotplug we need a place to call
ioctl(vfio_kvm_device_fd, KVM_DEV_VFIO_GROUP_SET_SPAPR_TCE).
Since the ioctl needs a LIOBN fd (from sPAPRTCETable) and a IOMMU group fd
(from VFIOGroup), vfio_listener_region_add() seems to be the only place
for this ioctl().

However this only works during boot time because the machine reset
happens strictly after all devices are finalized. When hotplug happens,
vfio_listener_region_add() is called when a memory listener is registered
but when this happens:
1. new group is not added to the container->group_list yet;
2. VFIO KVM device is unaware of the new IOMMU group.

This moves bits around to have all necessary VFIO infrastructure
in place for both initial startup and hotplug cases.

[aw: ie, register vfio groups with kvm prior to memory listener
registration such that kvm-vfio pseudo device ioctls are available
during the region_add callback]
