When running libvirtd from a build directory, libvirtd would load lock drivers from system directory unless explicitly overridden by setting LIBVIRT_LOCK_MANAGER_PLUGIN_DIR environment variable. Since we already autodetect driver directory if libvirt is build with driver modules, we can use the same trick to automagically set lock driver directory.

The following config elements now support a <vlan> subelements: within a domain: <interface>, and the <actual> subelement of <interface> within a network: the toplevel, as well as any <portgroup> Each vlan element must have one or more <tag id='n'/> subelements. If there is more than one tag, it is assumed that vlan trunking is being requested. If trunking is required with only a single tag, the attribute "trunk='yes'" should be added to the toplevel <vlan> element. Some examples: <interface type='hostdev'/> <vlan> <tag id='42'/> </vlan> <mac address='52:54:00:12:34:56'/> ... </interface> <network> <name>vlan-net</name> <vlan trunk='yes'> <tag id='30'/> </vlan> <virtualport type='openvswitch'/> </network> <interface type='network'/> <source network='vlan-net'/> ... </interface> <network> <name>trunk-vlan</name> <vlan> <tag id='42'/> <tag id='43'/> </vlan> ... </network> <network> <name>multi</name> ... <portgroup name='production'/> <vlan> <tag id='42'/> </vlan> </portgroup> <portgroup name='test'/> <vlan> <tag id='666'/> </vlan> </portgroup> </network> <interface type='network'/> <source network='multi' portgroup='test'/> ... </interface> IMPORTANT NOTE: As of this patch there is no backend support for the vlan element for *any* network device type. When support is added in later patches, it will only be for those select network types that support setting up a vlan on the host side, without the guest's involvement. (For example, it will be possible to configure a vlan for a guest connected to an openvswitch bridge, but it won't be possible to do that for one that is connected to a standard Linux host bridge.)

To allow for the possibility of vlan "trunks", which have more than one vlan tag associated with them, we need a vlan struct. Since it will be used by multiple files in src/util, src/conf, src/network, and src/qemu, it must be defined in src/util. Unfortunately there isn't currently a common file for simple netdev data definitions, so I created a new file.

Currently there is a hook function that is invoked when a new client connection comes in, which allows an app to setup private data. This setup will make it difficult to serialize client state during process re-exec(). Change to a model where the app registers a callback when creating the virNetServerPtr instance, which is used to allocate the client private data immediately during virNetClientPtr construction.

This patch adds three utility functions that operate on virNetDevVPortProfile objects. * virNetDevVPortProfileCheckComplete() - verifies that all attributes required for the type of the given virtport are specified. * virNetDevVPortProfileCheckNoExtras() - verifies that there are no attributes specified which are inappropriate for the type of the given virtport. * virNetDevVPortProfileMerge3() - merges 3 virtports into a single, newly allocated virtport. If any attributes are specified in more than one of the three sources, and do not exactly match, an error is logged and the function fails. These new functions depend on new fields in the virNetDevVPortProfile object that keep track of whether or not each attribute was specified. Since the higher level parse function doesn't yet set those fields, these functions are not actually usable yet (but that's okay, because they also aren't yet used - all of that functionality comes in a later patch.) Note that these three functions return 0 on success and -1 on failure. This may seem odd for the first two Check functions, since they could also easily return true/false, but since they actually log an error when the requested condition isn't met (and should result in a failure of the calling function), I thought 0/-1 was more appropriate.

The current virRandomBits() API is only usable if the caller wants a random number in the range [0, n-1) where n is a power of two. This adds a virRandom() API which generates a double in the range [0.0,1.0) with 48 bits of entropy. It then also adds a virRandomInt(uint32_t max) API which generates an unsigned in the range [0,@max) Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

libvirt creates invalid commands if wrong locale is selected. For example with locale that uses comma as a decimal point, JSON commands created with decimal numbers are invalid because comma separates the entries in JSON. Fortunately even when decimal point is affected, thousands grouping is not, because for grouping to be enabled with *printf, there has to be an apostrophe flag specified (and supported). This patch adds specific internal function for converting doubles to strings with C locale.

The meat of this patch is just moving the calls to virNWFilterRegisterCallbackDriver from each hypervisor's "register" function into its "initialize" function. The rest is just code movement to allow that, and a new virNWFilterUnRegisterCallbackDriver function to undo what the register function does. The long explanation: There is an array in nwfilter called callbackDrvArray that has pointers to a table of functions for each hypervisor driver that are called by nwfilter. One of those function pointers is to a function that will lock the hypervisor driver. Entries are added to the table by calling each driver's "register" function, which happens quite early in libvirtd's startup. Sometime later, each driver's "initialize" function is called. This function allocates a driver object and stores a pointer to it in a static variable that was previously initialized to NULL. (and here's the important part...) If the "initialize" function fails, the driver object is freed, and that pointer set back to NULL (but the entry in nwfilter's callbackDrvArray is still there). When the "lock the driver" function mentioned above is called, it assumes that the driver was successfully loaded, so it blindly tries to call virMutexLock on "driver->lock". BUT, if the initialize never happened, or if it failed, "driver" is NULL. And it just happens that "lock" is always the first field in driver so it is also NULL. Boom. To fix this, the call to virNWFilterRegisterCallbackDriver for each driver shouldn't be called until the end of its (*already guaranteed successful*) "initialize" function, not during its "register" function (which is currently the case). This implies that there should also be a virNWFilterUnregisterCallbackDriver() function that is called in a driver's "shutdown" function (although in practice, that function is currently never called).

This introduces a fairly basic reference counted virObject type and an associated virClass type, that use atomic operations for ref counting. In a global initializer (recommended to be invoked using the virOnceInit API), a virClass type must be allocated for each object type. This requires a class name, a "dispose" callback which will be invoked to free memory associated with the object's fields, and the size in bytes of the object struct. eg, virClassPtr connclass = virClassNew("virConnect", sizeof(virConnect), virConnectDispose); The struct for the object, must include 'virObject' as its first member eg struct _virConnect { virObject object; virURIPtr uri; }; The 'dispose' callback is only responsible for freeing fields in the object, not the object itself. eg a suitable impl for the above struct would be void virConnectDispose(void *obj) { virConnectPtr conn = obj; virURIFree(conn->uri); } There is no need to reset fields to 'NULL' or '0' in the dispose callback, since the entire object will be memset to 0, and the klass pointer & magic integer fields will be poisoned with 0xDEADBEEF before being free()d When creating an instance of an object, one needs simply pass the virClassPtr eg virConnectPtr conn = virObjectNew(connclass); if (!conn) return NULL; conn->uri = virURIParse("foo:///bar") Object references can be manipulated with virObjectRef(conn) virObjectUnref(conn) The latter returns a true value, if the object has been freed (ie its ref count hit zero) Signed-off-by: NDaniel P.

All callers used the same initialization seed (well, the new viratomictest forgot to look at getpid()); so we might as well make this value automatic. And while it may feel like we are giving up functionality, I documented how to get it back in the unlikely case that you actually need to debug with a fixed pseudo-random sequence. I left that crippled by default, so that a stray environment variable doesn't cause a lack of randomness to become a security issue. * src/util/virrandom.c (virRandomInitialize): Rename... (virRandomOnceInit): ...and make static, with one-shot call. Document how to do fixed-seed debugging. * src/util/virrandom.h (virRandomInitialize): Drop prototype. * src/libvirt_private.syms (virrandom.h): Don't export it. * src/libvirt.c (virInitialize): Adjust caller. * src/lxc/lxc_controller.c (main): Likewise. * src/security/virt-aa-helper.c (main): Likewise. * src/util/iohelper.c (main): Likewise. * tests/seclabeltest.c (main): Likewise. * tests/testutils.c (virtTestMain): Likewise. * tests/viratomictest.c (mymain): Likewise.

Security manager is not a dynamically loadable driver, it's a common infrastructure similar to util, conf, cpu, etc. used by individual drivers. Such code is allowed to be linked into libvirt.so. This reverts commit ec5b7bd2 and most of aae5cfb6. This patch is supposed to fix virdrivermoduletest failures for qemu and lxc drivers as well as libvirtd's ability to load qemu and lxc drivers.
