It is no longer needed thanks to the great virfilewrapper.c. And this way we don't have to add a new set of functions for each prefixed path. While on that, add two functions that weren't there before, string and scaled integer reading ones. Also increase the length of the string being read by one to accompany for the optional newline at the end (i.e. change INT_STRLEN_BOUND to INT_BUFSIZE_BOUND).

This mock (which is actually not mock at all, see later) can redirect all accesses to a path into another path. There is no need to create mocks for particular directories, you just create a directory with all the data a redirect the test there. In the future, this should also be able to register callbacks for calls/paths, e.g. when the test is going to write into anything under "/sys/devices", call function fce(); Then in the open() call we would add information about the fd into some structure and in write() we would call fce() with parameters like @path to write to, @data to be written and pointer to optional return value, so that fce() itself could stop the call from happening or change its behaviour. But that's an idea for a latter day. This is not a mock because it will not be preloaded, but compiled in the test itself. See future patches for usage.

A previous commit changed the spec to use librbd1-devel on RHEL-7, since this replaces ceph-devel from RHEL-6: commit 6cfc8834 Author: Peter Krempa <pkrempa@redhat.com> Date: Thu Mar 5 11:40:54 2015 +0100 spec: Enable RBD storage driver in RHEL-7 Use correct package names too as they differ. RHEL-7 inherited this rename from Fedora though, so it should have also made Fedora use the new names. This was missed, because Fedora still provides a (deprecated) back-compat RPM for ceph-devel that just pulls in librbd1-devel (and others). Fixing this stops libvirt pulling Java into the build root in Fedora. Reviewed-by: NPavel Hrdina <phrdina@redhat.com> Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

The API docs extractor, ESX code generator and keycodemapdb tools rely on python. Historically every platform that this present, but with switch to Python3 by default, we're increasingly seeing installs without a /usr/bin/python. This tightens up the check during configure, so it exits immediately if python is missing, rather than leaving an empty $(PYTHON) make variable which leads to more obscure errors later. Also add it as a build dep for Mingw, since Fedora build roots no longer get python2 by default. This was not previously a major problem, since both ESX & API generated files were included in EXTRA_DIST, but the keycodemapdb generated files are not, so we require python all the time now.

After bdcf6e48 there is a crasher in libvirt. The commit assumes that priv->perf is always set. That is not true. For inactive domains, the priv->perf is not allocated as it is set in qemuProcessLaunch(). Now, usually we differentiate between accesses to inactive and active definition and it works just fine. Except for 'domstats'. There priv->perf is accessed without prior check for domain inactivity. While we could check for that, more robust solution is to make virPerfEventIsEnabled() accept NULL. How to reproduce: 1) ensure you have at least one inactive domain 2) virsh domstats Signed-off-by: NMichal Privoznik <mprivozn@redhat.com> Reviewed-by: NDaniel P. Berrange <berrange@redhat.com>

The problem resides in virHostdevUpdateActiveMediatedDevices which gets called during qemuProcessReconnect. The issue here is that virMediatedDeviceListAdd takes a pointer to the item to be added to the list to which VIR_APPEND_ELEMENT is used, which also clears the pointer. However, in this case only the local copy of the pointer got cleared, leaving the original pointing to valid memory. To sum it up, during cleanup phase, the original pointer is freed and the daemon crashes basically any time it would access it.

Use a local variable to hold data, rather than accessing the pointer after calling virMediatedDeviceListAdd (therefore VIR_APPEND_ELEMENT). Although not causing an issue at the moment, this change is a necessary prerequisite for tweaking virMediatedDeviceListAdd in a separate patch, which will take a reference for the source pointer (instead of pointer value) and will clear it along the way.

Even though there are several checks before calling this function and for some scenarios we don't call it at all (e.g. on disk hot unplug), it may be possible to sneak in some weird files (e.g. if domain would have RNG with /dev/shm/some_file as its backend).

While the code allows devices to already be there (by some miracle), we shouldn't try to create devices that don't belong to us. For instance, we shouldn't try to create /dev/shm/file because /dev/shm is a mount point that is preserved. Therefore if a file is created there from an outside (e.g. by mgmt application or some other daemon running on the system like vhostmd), it exists in the qemu namespace too as the mount point is the same. It's only /dev and /dev only that is different. The same reasoning applies to all other preserved mount points.

Currently, all we need to do in qemuDomainCreateDeviceRecursive() is to take given @device, get all kinds of info on it (major & minor numbers, owner, seclabels) and create its copy at a temporary location @path (usually /var/run/libvirt/qemu/$domName.dev), if @device live under /dev. This is, however, very loose condition, as it also means /dev/shm/* is created too. Therefor, we will need to pass more arguments into the function for better decision making (e.g. list of mount points under /dev). Instead of adding more arguments to all the functions (not easily reachable because some functions are callback with strictly defined type), lets just turn this one 'const char *' into a 'struct *'. New "arguments" can be then added at no cost. Signed-off-by: NMichal Privoznik <mprivozn@redhat.com> Reviewed-by: NCedric Bosdonnat <cbosdonnat@suse.com>

When setting up mount namespace for a qemu domain the following steps are executed: 1) get list of mountpoints under /dev/ 2) move them to /var/run/libvirt/qemu/$domName.ext 3) start constructing new device tree under /var/run/libvirt/qemu/$domName.dev 4) move the mountpoint of the new device tree to /dev 5) restore original mountpoints from step 2) Note the problem with this approach is that if some device in step 3) requires access to a mountpoint from step 2) it will fail as the mountpoint is not there anymore. For instance consider the following domain disk configuration: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/dev/shm/vhostmd0'/> <target dev='vdb' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/> </disk> In this case operation fails as we are unable to create vhostmd0 in the new device tree because after step 2) there is no /dev/shm anymore. Leave aside fact that we shouldn't try to create devices living in other mountpoints. That's a separate bug that will be addressed later. Currently, the order described above is rearranged to: 1) get list of mountpoints under /dev/ 2) start constructing new device tree under /var/run/libvirt/qemu/$domName.dev 3) move them to /var/run/libvirt/qemu/$domName.ext 4) move the mountpoint of the new device tree to /dev 5) restore original mountpoints from step 3) Signed-off-by: NMichal Privoznik <mprivozn@redhat.com> Reviewed-by: NCedric Bosdonnat <cbosdonnat@suse.com>

When we get a POLLHUP or VIR_EVENT_HANDLE_HANGUP event for a client, we still want to read from the socket to process any accumulated data. But doing so inevitably results in an error and a call to virNetClientMarkClose before we get to processing the hangup event (and another call to virNetClientMarkClose). However the close reason passed to the second virNetClientMarkClose call is ignored because another one was already set. We need to pass the correct close reason when marking the socket to be closed for the first time. https://bugzilla.redhat.com/show_bug.cgi?id=1373859Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

While fixing a bug with incorrectly freed memory in commit v3.1.0-399-g5498aa29, I accidentally broke persistent migration of transient domains. Before adding qemuDomainDefCopy in the path, the code just took NULL from vm->newDef and used it as the persistent def, which resulted in no persistent XML being sent in the migration cookie. This scenario is perfectly valid and the destination correctly handles it by using the incoming live definition and storing it as the persistent one. After the mentioned commit libvirtd would just segfault in the described scenario. https://bugzilla.redhat.com/show_bug.cgi?id=1446205Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

If we are encoding a block of data that is 16 bytes in length, we cannot leave it as 16 bytes, we must pad it out to the next block boundary, 32 bytes.

The parser had been clearing out *all* suggested device names for type='direct' (aka macvtap) interfaces. All of the code implementing macvtap allows for a user-specified device name, so we should allow it. In the case that an interface name starts with "macvtap" or "macvlan" though, we do still clear it out, just as we do with "vnet" (which is the prefix used for automatically generated tap device names), since those are the prefixes for the names we autogenerate for macvtap and macvlan devices.

Nothing that could happen during networkNotifyActualDevice() could justify unceremoniously killing the qemu process, but that's what we were doing. In particular, new code added in commit 85bcc022 (first appearred in libvirt-3.2.0) attempts to reattach tap devices to their assigned bridge devices when libvirtd restarts (to make it easier to recover from a restart of a libvirt network). But if the network has been stopped and *not* restarted, the bridge device won't exist and networkNotifyActualDevice() will fail. This patch changes networkNotifyActualDevice() and qemuProcessNotifyNets() to return void, so that qemuProcessReconnect() will soldier on regardless of what happens (any errors will still be logged though).

Currently we use iohelper for virFDStream implementation. This is because UNIX I/O can lie sometimes: even though a FD for a file/block device is set as unblocking, actual read()/write() can block. To avoid this, a pipe is created and one end is kept for read/write while the other is handed over to iohelper to write/read the data for us. Thus it's iohelper which gets blocked and not our event loop. This approach has two problems: 1) we are spawning a new process. 2) any exchange of information between daemon and iohelper can be done only through the pipe. Therefore, iohelper is replaced with an implementation in thread which is created just for the stream lifetime. The data are still transferred through pipe (for now), but both problems described above are solved.
