[libvirt] [PATCH] build: fix 'make -C src check' under subset builds
by Eric Blake 03 Oct '13

03 Oct '13

Another build failure detected on cygwin, where lxc is not built. The lxc_monitor_protocol.c file requires the use of $(XDR_CFLAGS), but should only be built on platforms where WITH_LXC is true; however, 'make -C src check' was unconditionally trying to build the .o file (and with the wrong CFLAGS) in order to validate the matching -structs file.

(EXTRA_DIST): Ensure that -structs files are shipped even when not built. (check-protocol): Declare unconditionally, now that the condition has been moved into PROTOCOL_STRUCTS.

[libvirt] [PATCH] Fix crash in libvirtd when events are registered & ACLs active
by Daniel P. Berrange 03 Oct '13

03 Oct '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> When a client disconnects from libvirtd, all event callbacks must be removed. This involves running the public API virConnectDomainEventDeregisterAny This code does not run in normal API dispatch context, so no identity was set. The result was that the access control drivers denied the attempt to deregister callbacks. The callbacks thus continued to trigger after the client was free'd causing fairly predictable use of free memory & a crash. This can be triggered by any client with readonly access when the ACL drivers are active. Signed-off-by: Daniel P.

[libvirt] [PATCH] qemu: check actual netdev type rather than config netdev type during init
by Laine Stump 03 Oct '13

03 Oct '13

This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1012834 Note that a similar problem was reported in: https://bugzilla.redhat.com/show_bug.cgi?id=827519 but the fix only worked for <interface type='hostdev'>, *not* for <interface type='network'> where the network itself was a pool of hostdevs. The symptom in both cases was this error message: internal error: Unable to determine device index for network device In both cases the cause was lack of proper handling for netdevs (<interface>) of type='hostdev' when scanning the netdev list looking for alias names in qemuAssignDeviceNetAlias() - those that aren't type='hostdev' have an alias of the form "net%d", while those that are hostdev use "hostdev%d". This special handling was completely lacking prior to the fix for Bug 827519 which was: When searching for the highest alias index, libvirt looks at the alias for each netdev and if it is type='hostdev' it ignores the entry. If the type is not hostdev, then it expects the "net%d" form; if it doesn't find that, it fails and logs the above error message. That fix works except in the case of <interface type='network'> where the network uses hostdev (i.e. the network is a pool of VFs to be assigned to the guests via PCI passthrough). In this case, the check for type='hostdev' would fail because it was done as: def->net[i]->type == VIR_DOMAIN_NET_TYPE_HOSTDEV (which compares what was written in the config) when it actually should have been: virDomainNetGetActualType(def->net[i]) == VIR_DOMAIN_NET_TYPE_HOSTDEV (which compares the type of netdev that was actually allocated from the network at runtime). Of course the latter wouldn't be of any use if the netdevs of type='network' hadn't already acquired their actual network connection yet, but manual examination of the code showed that this is never the case. While looking through qemu_command.c, two other places were found to directly compare the net[i]->type field rather than getting actualType: * qemuAssignDeviceAliases() - in this case, the incorrect comparison would cause us to create a "net%d" alias for a netdev with type='network' but actualType='hostdev'. This alias would be subsequently overwritten by the proper "hostdev%d" form, so everything would operate properly, but a string would be leaked. This patch also fixes this problem. * qemuAssignDevicePCISlots() - would defer assigning a PCI address to a netdev if it was type='hostdev', but not for type='network + actualType='hostdev'. In this case, the actual device usually hasn't been acquired yet anyway, and even in the case that it has, there is no practical difference between assigning a PCI address while traversing the netdev list or while traversing the hostdev list. Because changing it would be an effective NOP (but potentially cause some unexpected regression), this usage was left unchanged. --- src/qemu/qemu_command.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index ba102f4..e976466 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -817,7 +817,8 @@ qemuAssignDeviceNetAlias(virDomainDefPtr def, virDomainNetDefPtr net, int idx) for (i = 0; i < def->nnets; i++) { int thisidx; - if (def->nets[i]->type == VIR_DOMAIN_NET_TYPE_HOSTDEV) { + if (virDomainNetGetActualType(def->nets[i]) + == VIR_DOMAIN_NET_TYPE_HOSTDEV) { /* type='hostdev' interfaces have a hostdev%d alias */ continue; } @@ -987,8 +988,9 @@ qemuAssignDeviceAliases(virDomainDefPtr def, virQEMUCapsPtr qemuCaps) /* type='hostdev' interfaces are also on the hostdevs list, * and will have their alias assigned with other hostdevs. */ - if ((def->nets[i]->type != VIR_DOMAIN_NET_TYPE_HOSTDEV) && - (qemuAssignDeviceNetAlias(def, def->nets[i], i) < 0)) { + if (virDomainNetGetActualType(def->nets[i]) + != VIR_DOMAIN_NET_TYPE_HOSTDEV && + qemuAssignDeviceNetAlias(def, def->nets[i], i) < 0) { return -1; } } -- 1.7.11.7

I confirmed this analysis by adding a sleep(10) to the QEMU driver startup code, and then triggering a firewalld restart. Sure enough it crashed & burned with the same trace. The reason why it has suddenly hit us is that we are unlucky enough to have a firewalld update in Fedora repos at the same time as a libvirt update, and lots of people are pulling both updates down in one yum transaction! After wasting time figuring out how to avoid the race condition with mutexes and other synchronization ideas, I realized that the nwfilter code was in fact bogus. The only reason it gets a virConnectPtr is so that the code for reloading filters can access its nwfilterPrivateData field to get the virNWFilterDriverStatePtr object instance. This is insanely convoluted, since the nwfilter driver can trivially pass the driver state instance into the virNWFilterConfLayerInit method at startup. Thus these patches just rip out all use of virConnectPtr from the nwfilter driver code, thus avoiding the race with the QEMU driver initialization code. This also fixes the nwfilter driver in cases where the QEMU driver is disabled, but LXC driver still wants to use nwfilter. Daniel P.
