startPool creates the vHBA if it's not existed yet, stopPool destroys the vHBA. Also to support autostart, checkPool will creates the vHBA if it's not existed yet.

The helper iterates over sysfs, to find out the matched scsi host name by comparing the wwnn,wwpn pair. It will be used by checkPool and refreshPool of storage scsi backend. New helper getAdapterName is introduced in storage_backend_scsi.c, which uses the new util helper virGetFCHostNameByWWN to get the fc_host adapter name.

It's possible to support fc_host adapter for phyp driver too, but at this stage I'd like to not allow it when I'm not that clear how it works.

It's only used by iscsi backend.

node device driver names the HBA like "scsi_host5", but storage driver uses "host5", which could make the user confused. This changes them to be consistent. However, for back-compat reason, adapter name like "host5" is still supported.

This introduces 4 new attributes for storage pool source adapter. E.g. <adapter type='fc_host' parent='scsi_host5' wwnn='20000000c9831b4b' wwpn='10000000c9831b4b'/> Attribute 'type' can be either 'scsi_host' or 'fc_host', and defaults to 'scsi_host' if attribute 'name' is specified. I.e. It's optional for 'scsi_host' adapter, for back-compat reason. However, mandatory for 'fc_host' adapter and any new future adapter types. Attribute 'parent' is to specify the parent for the fc_host adapter. * docs/formatstorage.html.in: - Add documents for the 4 new attrs * docs/schemas/storagepool.rng: - Add RNG schema * src/conf/storage_conf.c: - Parse and format the new XMLs * src/conf/storage_conf.h: - New struct virStoragePoolSourceAdapter, replace "char *adapter" with it; - New enum virStoragePoolSourceAdapterType * src/libvirt_private.syms: - Export TypeToString and TypeFromString * src/phyp/phyp_driver.c: - Replace "adapter" with "adapter.data.name", which is member of the union of the new struct virStoragePoolSourceAdapter now. Later patch will add the checking, as "adapter.data.name" is only valid for "scsi_host" adapter. * src/storage/storage_backend_scsi.c: - Like above * tests/storagepoolxml2xmlin/pool-scsi-type-scsi-host.xml: * tests/storagepoolxml2xmlin/pool-scsi-type-fc-host.xml: - New test for 'fc_host' and "scsi_host" adapter * tests/storagepoolxml2xmlout/pool-scsi.xml: - Change the expected output, as the 'type' defaults to 'scsi_host' if 'name" specified now * tests/storagepoolxml2xmlout/pool-scsi-type-scsi-host.xml: * tests/storagepoolxml2xmlout/pool-scsi-type-fc-host.xml: - New test * tests/storagepoolxml2xmltest.c: - Include the test

When reading the inotify FD, we get back a sequence of struct inotify_event, each with variable length data following.

The virNetlinkCommand() method takes an 'unsigned char **' parameter to be filled with the received netlink message.

The way we do the cast inside virNetlinkCommand does not have any alignment issues. Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

By default, libtool builds two .o files for every .lo rule: src/foo.o - static builds src/.libs/foo.o - shared library builds But since commit ad42b34b disabled static builds, src/foo.o is no longer built by default. On a fresh checkout, this means our protocol check rules using pdwtags were testing a missing file, and thanks to a lousy behavior of pdwtags happily giving no output and 0 exit status (http://bugzilla.redhat.com/949034), we were merely claiming that "dwarves is too old" and skipping the test. However, if you swap between branches and do incremental builds, such as building v0.10.2-maint and then switching back to master, you end up with src/foo.o being leftover from its 0.10.2 state, and then 'make check' fails because the .o file does not match the protocol-structs file due to API additions in the meantime. A simpler fix would be to always look in .libs for the .o to be parsed; but since it is possible to pass ./configure options to tell libtool to do a static-only build with no shared .o, I went with the approach of finding the newest of the two files, whenever both exist. * src/Makefile.am (PDWTAGS): Ensure we test just-built file.

Currently when getting an instance of virCgroupPtr we will create the path in all cgroup controllers. Only at the virt driver layer are we attempting to filter controllers. This is bad because the mere act of creating the dirs in the controllers can have a functional impact on the kernel, particularly for performance. Update the virCgroupForDriver() method to accept a bitmask of controllers to use. Only create dirs in the controllers that are requested. When creating cgroups for domains, respect the active controller list from the parent cgroup Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

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.

This patch refactors various places to allow removing of the defaultConsoleTargetType callback from the virCaps structure. A new console character device target type is introduced - VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_NONE - to mark that no type was specified in the XML. This type is at the end converted to the standard VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_SERIAL. Other types that are different from this default have to be processed separately in the device post parse callback.

This patch adds instrumentation that will allow hypervisor drivers to fill and validate domain and device definitions after parsed by the XML parser. With this patch, after the XML is parsed, a callback to the driver is issued requesting to fill and validate driver specific details of the configuration. This allows to use sensible defaults and checks on a per driver basis at the time the XML is parsed. Two callback pointers are stored in the new virDomainXMLConf object: * virDomainDeviceDefPostParseCallback (devicesPostParseCallback) - called for a single device parsed and for every single device in a domain config. A virDomainDeviceDefPtr is passed along with the domain definition and virCaps. * virDomainDefPostParseCallback, (domainPostParseCallback) - A callback that is meant to process the domain config after it's parsed. A virDomainDefPtr is passed along with virCaps. Both types of callbacks support arbitrary opaque data passed for the callback functions. Errors may be reported in those callbacks resulting in a XML parsing failure.
