Cole Robinson 856965b362 qemu: fix qemu.conf security_driver
Since a9331394 (first release v2.1.0), specifying a manual
security_driver setting in qemu.conf causes the daemon to fail to
start, erroring with 'Duplicate security driver X'.

The duplicate checking was incorrectly comparing every entry
against itself, guaranteeing a false positive.

Cole Robinson 6fd8a1e614 test: Add scsi vport nodedev to test:///default
A nodedev device definition like this is required for testing
NodeDeviceCreateXML and NodeDeviceDestroy. So unless it's part

Cole Robinson 03ce132808 conf: Remove dead console compat formatting
This code was attempting to handle some implicit <console> XML
formatting for manually assembled DomainDef, since previously the

Nowadays it's done via virDomainDefPostParse ->
virDomainDefAddConsoleCompat, which all manual DomainDef builders
already call, so we can drop this workaround.

Cole Robinson 383833e230 qemu: Call virDomainDefPostParse via CONFIG hotplug
hotplug APIs with the AFFECT_CONFIG flag are essentially replicating
'insert <device> into XML document, and redefine XML'. Thinking of
it this way, it's natural that we call virDomainDefPostParse after
manually editing the XML here.

Not only does doing so allow us to drop a bunch of open coded calls
to qemuDomainAssignAddresses, but it also means we are going through
the standard channels for XML validation and potentially catching
errors in user submitted XML.

Cole Robinson 5d7314bbcf qemu: Assign device addresses in PostParse
This wires up qemuDomainAssignAddresses into the new

Cole Robinson b6238738ea rpc: use virNetMessageClearPayload in client
This removes the opencoded payload freeing in the client, to use
the shared virNetMessageClearPayload call. Two changes:

- ClearPayload sets nfds=0, which fixes a potential crash if
  an error path called virNetMessageFree/Clear on the message
  after fds was free'd
- We drop the inner loop VIR_FORCE_CLOSE... this may mean fds are
  kept open a little bit longer if the call is blocking but in

Cole Robinson a5481546d6 fdstream: don't raise error on SIGPIPE if abort requested
The iohelper dies on SIGPIPE if the stream is closed before all data
is processed. IMO this should be an error condition for virStreamFinish
according to docs like:

  * This method is a synchronization point for all asynchronous
  * errors, so if this returns a success code the application can
  * be sure that all data has been successfully processed.

However for virStreamAbort, not so much:

  * Request that the in progress data transfer be cancelled
  * abnormally before the end of the stream has been reached.
  * For output streams this can be used to inform the driver
  * that the stream is being terminated early. For input
  * streams this can be used to inform the driver that it
  * should stop sending data.

Without this, virStreamAbort will realistically always error for
active streams like domain console. So, treat the SIGPIPE case
as non-fatal if abort is requested.

Note, this will only affect an explicit user requested abort. An
abnormal abort, like from a server error, always raises an error
in the daemon.
2016-05-02 10:13:05 -04:00
Cole Robinson 66a03d0af2 daemon: stream: Don't force error when client aborts
Every time a client aborts a stream via the virStreamAbort API,
the daemon always logs an error like:

  error : daemonStreamHandleAbort:617 : stream aborted at client request

and that same error is returned to the client. Meaning virStreamAbort
always returns -1, which seems strange.

This reworks the error handling to only raise an error on virStreamAbort
if the actual server side abort call raises an error. This is similar
to how virStreamFinish works.

If the abort code path is triggered by an unexpected message type
then we continue to raise an unconditional error. Also drop a redundant
VIR_WARN call there, since virReportError will raise a VIR_ERROR anyways

Cole Robinson 75e1999042 daemon: stream: set stream->closed on removal
These are the only places where we don't set stream->closed when
aborting the stream. This leads to spurious errors when the client
hangs up unexpectedly:

error : virFDStreamUpdateCallback:127 : internal error: stream is not open
2016-05-02 10:13:04 -04:00
Cole Robinson a680dde643 daemon: stream: don't update events if stream->closed
Calling virStreamFinish prematurely seems to trigger this code path
even after the stream is closed, which ends up hitting this error
message later:

error : virFDStreamUpdateCallback:127 : internal error: stream is not open

Skip this function if stream->closed, which is used in many other places
like read/write handlers
2016-05-02 10:13:04 -04:00
Cole Robinson e7407872a4 daemon: stream: Close stream on send failure
This is the only place in daemon/stream.c that sets

Cole Robinson 441e881e9a nwfilter: Save config to disk if we generated a UUID
libvirt-daemon-config-nwfilter will put a bunch of xml configs
into /etc/libvirt/nwfilter. These configs don't hardcode a UUID
and depends on libvirt to generate one. However the generated UUID
is never saved to disk, unless the user manually calls Define.

This makes daemon reload quite noisy with many errors like:

error : virNWFilterObjAssignDef:3101 : operation failed: filter 'allow-incoming-ipv4' already exists with uuid 50def3b5-48d6-46a3-b005-cc22df4e5c5c

Because a new UUID is generated every time the config is read from
disk, so libvirt constantly thinks it's finding a new nwfilter.

Detect if we generated a UUID when the config file is loaded; if so,
resave the new contents to disk to ensure the UUID is persisteny.

This is similar to what was done in commit a47ae7c0 with virtual
networks and generated MAC addresses

Cole Robinson ab05abdbc3 nwfilter: Fix potential locking problems on ObjLoad failure
In virNWFilterObjLoad we can still fail after virNWFilterObjAssignDef,
but we don't unlock and free the created virNWFilterObjPtr in the
cleanup path.

The bit we are trying to do after AssignDef is just STRDUP in the
configFile path. However caching the configFile in the NWFilterObj
is largely redundant and doesn't follow the same pattern we use
for domain and network objects.

So just remove all the configFile caching which fixes the latent
bug as a side effect.

Trying to define a pool name containing an embedded '/'

This patch explicitly rejects names containing a '/'

Besides our stateful driver, there are two other storage impls:
esx and phyp. esx doesn't support pool creation, so this should
doesn't apply.

phyp does support pool creation, and the name is passed to the
'mksp' tool, which google doesn't reveal whether it accepts '/'
or not. IMO the likeliness of this impacting any users is near zero

Trying to define a network name containing an embedded '/'

This patch explicitly rejects names containing a '/'

Besides the network bridge driver, the only other network
implementation is a very thin one for virtualbox, which seems to

accept '/' anyways, so I think this is fine to do unconitionally.

to avoid this validation check, which is enabled in every
non-stateful driver that already has xmlopt handling wired up.

 '/foo', however at least for the qemu driver that falls over
 later when starting qemu)

Cole Robinson 84371303d8 remote: Don't reject remote polkit if client lacks support

polkit auth, the connection will fail with:

error: failed to connect to the hypervisor
error: authentication failed: unsupported authentication type 2

This is because the client side portion of the polkit handling is
compiled out. However, nothing polkit specific is actually required
of the client.

Fix that error by unconditionally compiling the basic polkit client
handling.

This unifies the test scripts to all use the similar pattern added for

- Drops redundant abs_* definitions, which are set by test-lib.sh
- Drops unnecessary srcdir variable which was only used for sourcing

Behavior changes:

- srcdir can no longer be overwritten, but I don't know why anyone would
    really need to...
- Script VERBOSE setting no longer prints commands executed by test-lib.sh.

Cole Robinson fa90464faa tests: remove 'reconnect' and 'statstest'
These old tests expect to run against a real xen connection via
xend running on the host. Our intentions for the test suite are
that it doesn't require interacting with any specific host resources,
so these don't really belong here.

the case when a config file doesn't end in a newline, and manually
append a newline to the content before parsing

Cole Robinson 272c622475 storage: drop the plumbing needed for kvm-img/qcow-create
Remove all the plumbing needed for the different qcow-create/kvm-img
non-raw file creation.

We can drop the error messages because CreateQemuImg will thrown an
error for us but with slightly less fidelity (unable to find qemu-img),
which I think is acceptable given the unlikeliness of that error in
practice.

Cole Robinson 487d211d20 storage: remove support for /usr/bin/kvm-img
This an ubuntu/debian packaging convention. At one point it may have
been an actually different binary, but at least as of ubuntu precise
(the oldest supported ubuntu distro, released april 2012) kvm-img is
just a symlink to qemu-img for back compat.

I think it's safe to drop support for it

Cole Robinson 1196fed2e3 storage: remove support for /usr/bin/qcow-create
qcow-create was a crippled qemu-img impl that shipped with xen. I
think supporting this was only relevant for really old distros
that didn't have a proper qemu package, like early RHEL5. I think
it's fair to drop support

Cole Robinson cdb4caac81 network: Don't use ERR_NO_SUPPORT for invalid net-update requests
VIR_ERR_NO_SUPPORT maps to the error string

    this function is not supported by the connection driver

and is largely only used for when a driver doesn't have any
implementation for a public API. So its usage with invalid
net-update requests is a bit out of place. Instead use
VIR_ERR_OPERATION_UNSUPPORTED which maps to:

    Operation not supported

And is what qemu's hotplug routines use in similar scenarios

Cole Robinson 3b9100a4d2 Revert "daemon: use socket activation with systemd"
This reverts commit 1e9808d3a1.

We shouldn't advertise libvirtd.socket activation, since currently
it means VM/network/... autostart won't work as expected.

We tried to find a middle ground by installing the config file without
an [Install] section, since systemd won't allow .socket to be enabled
without one... or at least it did do that; presently on f24 it allows
activating the socket quite happily. This also caused user confusion[1]

Just remove the socket file. I've filed a new RFE to track coming up
with a solution to the autostart problem[2], we can point users at that
if there's more confusion:

Cole Robinson 0d1579572a Explicitly error on uri=qemu://system
It's a fairly common error that a user tries to connect to a URI
like qemu://system or qemu://session (missing a slash). This errors
like:

$ virsh --connect qemu://session
error: failed to connect to the hypervisor
error: Unable to resolve address 'session' service '16514': No address associated with hostname

If you already know that the standard qemu URI has 3 slashes, that
error will make it obvious enough. But new user's may not get it.
There's even a RHEL support page explicitly mentioning it!:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Virtualization_Deployment_and_Administration_Guide/sect-Troubleshooting-Common_libvirt_errors_and_troubleshooting.html

Catch this error early in libvirt.c virConnectOpen for qemu (and vbox
which has similar rules

The common idiom in the driver API implementations is roughly:

seem to serve much use. Drop them

Cole Robinson dae0e22714 qemu: migration: Drop dead VNC cookie handling
The only caller of this code is:

    for (i = 0; i < dom->def->ngraphics; i++) {
       if (dom->def->graphics[i]->type == VIR_DOMAIN_GRAPHICS_TYPE_SPICE) {
           if (!(mig->graphics =
                 qemuMigrationCookieGraphicsAlloc(driver, dom->def->graphics[i])))
               return -1;
           mig->flags |= QEMU_MIGRATION_COOKIE_GRAPHICS;
           break;
       }
    }

So this is never triggered for VNC, and in fact VNC has no support for
seamless migration anyways so that seems correct. Drop the dead VNC
handling.

Cole Robinson 8f8c0feb11 storage: mpath: Don't error on target_type=NULL
We use device-mapper to enumerate all dm devices, and filter out
the list of multipath devices by checking the target_type string
name. The code however cancels all scanning if we encounter
target_type=NULL

I don't know how to reproduce that situation, but a user was hitting
it in their setup, and inspecting the lvm2/device-mapper code shows
many places where !target_type is explicitly ignored and processing
continues on to the next device. So I think we should do the same
