With some authentication mechanism (PLAIN for example), sasl_client_start()
can return SASL_OK, which translates to virNetSASLSessionClientStart()
returning VIR_NET_SASL_COMPLETE.
cyrus-sasl documentation is a bit vague as to what to do in such situation,
but upstream clarified this a bit in
http://asg.andrew.cmu.edu/archive/message.php?mailbox=archive.cyrus-sasl&msg=10104
When we got VIR_NET_SASL_COMPLETE after virNetSASLSessionClientStart() and
if the remote also tells us that authentication is complete, then we should
end the authentication procedure rather than forcing a call to
virNetSASLSessionClientStep(). Without this patch, when trying to use SASL
PLAIN, I get:
error :authentication failed : Failed to step SASL negotiation: -1
(SASL(-1): generic failure: Unable to find a callback: 32775)
This patch is based on a spice-gtk patch by Dietmar Maurer.
The array of sasl_callback_t callbacks which is passed to sasl_client_new()
must be kept alive as long as the created sasl_conn_t object is alive as
cyrus-sasl uses this structure internally for things like logging, so
the memory used for callbacks must only be freed after sasl_dispose() has
been called.

remote: fix dom->id after virDomainCreateWithFlags
The virDomainCreateWithFlags remote client helper was made to
invoke REMOTE_PROC_DOMAIN_LOOKUP_BY_UUID to refresh the 'id'
of the domain, following the pattern used in the previous
virDomainCreate method impl.
The remote protocol for virDomainCreateWithFlags though did
actually fix the design flaw in virDomainCreate, by directly
returning the new domain info. For some reason, this data was
never used. So we can just use that data now instead.

Without the socket path explicitly specified, the remote driver tried to
connect to the "/system" instance socket even if "/session" was
specified in the uri. With this patch this configuration now produces an
error.
It is still possible to initiate a session connection with specifying
the path to the socket manually and also manually starting the session
daemon. This was also possible prior to this patch,
This is a minimal fix. We may decide to support remote session
connections using ssh but this will require changes to the remote driver
code so this fix shouldn't cause regressions in the case we decide to do
that.
The same issue as (already fixed) in virDomainCreate -
REMOTE_PROC_DOMAIN_CREATE_WITH_FLAGS doesn't return new domain ID, only
-1 on error or 0 on success.
Besides this one fix it is more general problem - local domain object
ID can desynchronize with the real one, for example in case of another
client creates/destroys domain in the meantime. Perhaps virDomainGetID
should be called remotely (with all performance implications...)? Or
some event-based notification used?

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
This requires a custom function for remoteNodeDeviceDetachFlags,
because it is named *NodeDevice, but it goes through the hypervisor
driver rather than nodedevice driver, and so it uses privateData
instead of nodeDevicePrivateData. (It has to go through the hypervisor
driver, because that is the driver that knows about the backend drivers
that will perform the pci device assignment).
Ensure that all drivers implementing public APIs use a
naming convention for their implementation that matches

The last Viktor's effort to fix the race and memory corruption unfortunately
wasn't complete in the case the close callback was not registered in an
connection. At that time, the trail of event's that I'll describe later could
still happen and corrupt the memory or cause a crash of the client (including
the daemon in case of a p2p migration).
Consider the following prerequisities and trail of events:
Let's have a remote connection to a hypervisor that doesn't have a close
callback registered and the client is using the event loop. The crash happens in
cooperation of 2 threads. Thread E is the event loop and thread W is the worker
that does some stuff. R denotes the remote client.
1.) W - The client finishes everything and sheds the last reference on the client
2.) W - The virObject stuff invokes virConnectDispose that invokes doRemoteClose
3.) W - the remote close method invokes the REMOTE_PROC_CLOSE RPC method.
4.) W - The thread is preempted at this point.
5.) R - The remote side receives the close and closes the socket.
6.) E - poll() wakes up due to the closed socket and invokes the close callback
7.) E - The event loop is preempted right before remoteClientCloseFunc is called
8.) W - The worker now finishes, and frees the conn object.
9.) E - The remoteClientCloseFunc accesses the now-freed conn object in the
attempt to retrieve pointer for the real close callback.
10.) Kaboom, corrupted memory/segfault.
This patch tries to fix this by introducing a new object that survives the
freeing of the connection object. We can't increase the reference count on the
connection object itself or the connection would never be closed, as the
connection is closed only when the reference count reaches zero.
The new object - virConnectCloseCallbackData - is a lockable object that keeps
the pointers to the real user registered callback and ensures that the
connection callback is either not called if the connection was already freed or
that the connection isn't freed while this is being called.
remoteDeserializeTypedParameters can now be called with either
preallocated params array (size of which is announced by nparams) or it
can allocate params array according to the number of parameters received
from the server.
Like virNodeDeviceCreateXML, virNodeDeviceLookupSCSIHostByWWN
has to be treated specially when generating the RPC codes. Also
new rules are added in fixup_name to keep the name SCSIHostByWWN.
Upon successful return of virNetClientStreamEventAddCallback() the
allocated cbdata field will be freed by virNetClientStreamEventRemoveCallback()
as cbOpaque using the free function remoteStreamCallbackFree().
This patch adds a new API, virDomainOpenChannel, that uses streams to
connect to a virtio channel on a guest. This creates a secure
communication channel between a guest and a libvirt client.
This behaves the same as virDomainOpenConsole, except on channels
instead of console/serial/parallel devices.
https://bugzilla.redhat.com/show_bug.cgi?id=866524
Since the virConnect object is not locked wholely when doing
virConenctDispose, a thread can get the lock and thus might
cause the race.

The above race is caused by the eventLoop thread tries to handle
the net client event by calling the callback set by:
virNetClientSetCloseCallback(priv->client,
remoteClientCloseFunc,
conn, NULL);
I.E. remoteClientCloseFunc, which lock/unlock the virConnect object.
This patch is to fix the bug by setting the callback to NULL when
doRemoteClose.
Currently to deal with auto-shutdown libvirtd must periodically
poll all stateful drivers. Thus sucks because it requires
acquiring both the driver lock and locks on every single virtual
machine. Instead pass in a "inhibit" callback to virStateInitialize
which drivers can invoke whenever they want to inhibit shutdown
due to existance of active VMs.

This will simplify the refactoring of the ESX storage driver to support
a VMFS and an iSCSI backend.
One of the tasks the storage driver needs to do is to decide which backend
driver needs to be invoked for a given request. This approach extends
virStoragePool and virStorageVol to store extra parameters:
1. privateData: stores pointer to respective backend storage driver.
2. privateDataFreeFunc: stores cleanup function pointer.
virGetStoragePool and virGetStorageVol are modfied to accept these extra
parameters as user params. virStoragePoolDispose and virStorageVolDispose
checks for cleanup operation if available.
The private data pointer allows the ESX storage driver to store a pointer
to the used backend with each storage pool and volume. This avoids the need
to detect the correct backend in each storage driver function call.
The libvirt coding standard is to use 'function(...args...)'
instead of 'function (...args...)'. A non-trivial number of
places did not follow this rule and are fixed in this patch.

It turns out that calling virNodeGetCPUMap(conn, NULL, NULL, 0)
is both useful, and with Viktor's patches, common enough to
optimize. Since this interface hasn't been released yet, we
can change the RPC call.
A bit more background on the optimization - learning the cpu count
is a single file read (/sys/devices/system/cpu/possible), but
learning the number of online cpus can possibly trigger a file
read per cpu, depending on the age of the kernel, and all wasted
if the caller passed NULL for both arguments.

to work with transient devices, wake-ups etc. This patch is not
aiming for that functionality.
When auto-probing hypervisor drivers, the conn->uri field will
initially be NULL. Care must be taken not to access members
when doing auth lookups in the config file

Currently we search along the hard-coded names:
SBINDIR "/libvirtd"
SBINDIR "/libvirtd_dbg"
but if the environment variable $LIBVIRTD_PATH is set to the
name of the libvirtd binary, that is used instead. Fix the
error message so it accurately reflects current behaviour
($PATH is NOT searched).

that's needed are:
* src/remote/remote_driver.c: add pointer to autogenerated
remoteNetworkUpdate to the function table for the remote
network driver.

item to the remote_procedure enum for this function.

The remote driver first looks at the libvirt auth config file to
fill in any credentials. It then invokes the auth callback for
any remaining credentials. It was accidentally invoking the
auth callback even if there were not any more credentials
required.

Introduce 2 APIs to support emulator threads in remote driver.
1) remoteDomainPinEmulator: call driver api, such as qemudDomainPinEmulator.
2) remoteDomainGetEmulatorPinInfo: call driver api, such as qemudDomainGetEmulatorPinInfo.
They are similar to remoteDomainPinVcpuFlags and remoteDomainGetVcpuPinInfo.

This patch adds URI options to support libssh2 transport in the remote
driver.
A new transport sceme is introduced eg. "qemu+libssh2://..." that
utilizes the libssh2 code added in previous patches.
The libssh2 code requires the authentication callback to be able to
perform keyboard-interactive authentication or to ask t passprhases or
add host keys to known hosts database.
Added URI components:
- known_hosts - path to a knownHosts file in OpenSSH format to check
for known ssh host keys
- known_hosts_verify - how to deal with server key verification:
* "normal" (default) - ask to add new keys
* "auto" - automaticaly add new keys
* "ignore" - don't validate host keys
- sshauth - authentication methods to use. Default is
"agent,privkey,keyboard-interactive". It's a comma separated
string of methods to try while authenticating. The order is
preserved. Some of the methods may require additional
parameters.
Locations of the known_hosts file and private keys are set to default
values if they're present. (~/.ssh/known_hosts, ~/.ssh/id_rsa,
~/.ssh/id_dsa)
This patch updates libvirt's API to allow applications to inspect the
full list of security labels of a domain.

Currently the virNetClientPtr constructor will always register
the async IO event handler and the keepalive objects. In the
case of the lock manager, there will be no event loop available
nor keepalive support required. Split this setup out of the
constructor and into separate methods.
The remote driver will enable async IO and keepalives, while
the LXC driver will only enable async IO

Remove spaces before function calls and some other coding nits in some
parts of the remote driver and refactor getting of URI argument
components into variables used by libvirt later on.
