[libvirt] [BUG] xenInotify/keep-alive double-free
by Philipp Hahn 02 Apr '14

02 Apr '14

Hello, There seems to be a double-free bug in libvirt; I've checked libvirt 0.9.12 and 1.2.3: With 0.9.12 xenUnifiedOpen() passes a pointer of "conn" to xenInotifyOpen(), which passes it to virEventAddHandle(...opaque=conn...). After successfully defining a new domain inotify picks up the newly created directory and generates an event, which is processes when virsh already dropped its last public reference to the domain and subsequently already freed the connection. Since *conn is not zero-filled, the data is still valid and usable, but virsh the terminates on double-freeing some internal data. I can reproduce by it doing: virsh undefine $DOM virsh -c xen:// define $DOM.xml For 1.2.3 something similar seems to happen with the keep-alive: $ grep unref ~/BUG/31032_virsh-define-segv.log virUnrefDomain:276 : unref domain 0x7f4ec4003fe0 ucs32-64-segv 1 virReleaseDomain:246 : unref connection 0x917650 2 virUnrefDomain:276 : unref domain 0x934460 ucs32-64-segv 1 virReleaseDomain:246 : unref connection 0x917650 2 virUnrefConnect:145 : unref connection 0x917650 1 virUnrefDomain:276 : unref domain 0x7f4ec4004060 ucs32-64-segv 1 virReleaseDomain:246 : unref connection 0x917650 1 Notice that there are two lines for "unref connection ... 1"! My gut feeling is that libvirt should also increment the reference counter for internal references to delay freeing still used data and add a second counter to track external references, which is used to start closing down things. Comments and ideas welcomed.

[libvirt] [bug?] unix sockets opened via chardev devices not being closed on shutdown
by Chris Friesen 01 Apr '14

01 Apr '14

I have a case where I'm creating a virtio channel between the host and guest using something like this: <channel type="unix"> <source mode="bind" path="/path/in/host/instance_name"/> <target type="virtio" name="name_in_guest"/> </channel> When qemu is started up this gets created as expected, but when qemu is shut down the unix socket is left in the filesystem. It seems to me that libvirt should be deleting this unix socket the same way that it deletes the monitor socket in qemuProcessStop(). Anyone else trying to delete it is going to be subject to race conditions since they can't know whether or not a virtual machine has been (re)created that wants to use the same socket path. Chris

[libvirt] [PATCH] maint: ensure src/ directory includes are clean
by Eric Blake 01 Apr '14

01 Apr '14

In 'make syntax-check', we have a rule that prevents layering violations between the various files in src. However, we forgot to treat conf/ and the more recently-added access/ as lower-level directories, and were not detecting cases where they might have used a driver file. Also, it's not nice that qemu can use storage/ but none of the other drivers could do so. * cfg.mk (sc_prohibit_cross_inclusion): Tighten rules for conf/ and access/, let all other drivers use storage/. Signed-off-by: Eric Blake <eblake(a)redhat.com> --- I noticed this because of my work on domain_conf.h: I want to share a struct between util/virstoragefile and conf/domain_conf, and ran into a syntax check when I tried to make util/ depend on conf/.

[libvirt] [PATCH 0/n] round 2 of storage chain refactoring
by Eric Blake 01 Apr '14

01 Apr '14

In round 1, I split out a new struct in domain_conf.h. This starts round 2: moving the struct into util/virstoragefile.h, so it can be shared by domain, snapshot, and existing virstoragefile backing chain operations. It's turned out to be a bigger process than I first thought, so I've tried splitting it into smaller patches to ease review. I also want to get review started on the parts I have compiling, while still working on the rest of the series, since I know that at least Peter will be heavily impacted by some of the changes in this series.

In https://bugzilla.redhat.com/show_bug.cgi?id=1080613 , something is causing StorageVolGetXML to fail, but it's not raising any error message. Code inspection found that most users of VolOpen are susceptible to error reporting issues.

Patch 4 fixes up the reporting issue. v2: Jan's suggestion to only report an error if caller passed in VOL_OPEN_ERROR Cole Robinson (4): storage: Rename UpdateVolInfoFlags to UpdateVolInfo storage: move block format lookup to shared UpdateVolInfo storage: Rename VolOpenCheckMode to VolOpen storage: Report error from VolOpen if proper flag is passed src/storage/storage_backend.c | 260 ++++++++++++++++++---------------- src/storage/storage_backend.h | 18 +-- src/storage/storage_backend_disk.c | 3 +- src/storage/storage_backend_fs.c | 25 ++-- src/storage/storage_backend_logical.c | 11 +- src/storage/storage_backend_mpath.c | 36 +---- src/storage/storage_backend_scsi.c | 43 +----- 7 files changed, 175 insertions(+), 221 deletions(-) -- 1.8.5.3

[libvirt] [for-1.2.3 PATCHv3] gluster: Fix "key" attribute for gluster volumes
by Peter Krempa 01 Apr '14

01 Apr '14

According to our documentation the "key" value has the following meaning: "Providing an identifier for the volume which identifies a single volume." The currently used keys for gluster volumes consist of the gluster volume name and file path. This can't be considered unique as a different storage server can serve a volume with the same name. Unfortunately I wasn't able to figure out a way to retrieve the gluster volume UUID which would avoid the possibility of having two distinct keys identifying a single volume. Use the full URI as the key for the volume to avoid the more critical ambiguity problem and document the possible change to UUID. --- Notes: Version 3: - fix the example too, also state that UUID might be used - repost so we don't have yet another release containing this docs/storage.html.in | 8 +++++--- src/storage/storage_backend_gluster.c | 10 ++++++++-- 2 files changed, 13 insertions(+), 5 deletions(-) diff --git a/docs/storage.html.in b/docs/storage.html.in index 2706bc5..4bbf378 100644 --- a/docs/storage.html.in +++ b/docs/storage.html.in @@ -711,12 +711,14 @@ correspond to the files that can be found when mounting the gluster volume.

In https://bugzilla.redhat.com/show_bug.cgi?id=1080613 , something is causing StorageVolGetXML to fail, but it's not raising any error message. Code inspection found that most users of VolOpen are susceptible to error reporting issues. The first 3 patches are some code reorganization and cleanups that make it easier to identify the VolOpen callers. Patch 4 fixes up the reporting issue.

[libvirt] [PATCH tck 0/6] Fix tests which need a full OS image
by Daniel P. Berrange 31 Mar '14

31 Mar '14

A bunch of tests currently attempt to kickstart a full Fedora OS image install. Everytime I try to update this kickstart to a new version of Fedora it causes no end of pain. Switch the tests over to use Richard Jones' virt-builder command which is part of libguestfs. This makes it trivial to deploy and customize full OS images from pre-built templates. Mike - does Suse include a new enough version of libguestfs to get access to the 'virt-builder' tool yet ? Daniel P.

[libvirt] [PATCH] bhyve: don't leak tap devices on failures
by Roman Bogorodskiy 31 Mar '14

31 Mar '14

On failures, virBhyveProcessStart() does not cleanup network interfaces that could be created by virBhyveProcessBuildBhyveCmd(), which results in a leaked tap device. To fix that, extract network cleanup code to bhyveNetCleanup() and use it in cleanup stage of virBhyveProcessStart(). --- src/bhyve/bhyve_process.c | 34 ++++++++++++++++++++++------------ 1 file changed, 22 insertions(+), 12 deletions(-) diff --git a/src/bhyve/bhyve_process.c b/src/bhyve/bhyve_process.c index b37855e..a557bc5 100644 --- a/src/bhyve/bhyve_process.c +++ b/src/bhyve/bhyve_process.c @@ -63,6 +63,24 @@ bhyveProcessAutoDestroy(virDomainObjPtr vm, return vm; } +static void +bhyveNetCleanup(virDomainObjPtr vm) +{ + size_t i; + + for (i = 0; i < vm->def->nnets; i++) { + virDomainNetDefPtr net = vm->def->nets[i]; + int actualType = virDomainNetGetActualType(net); + + if (actualType == VIR_DOMAIN_NET_TYPE_BRIDGE) { + ignore_value(virNetDevBridgeRemovePort( + virDomainNetGetActualBridgeName(net), + net->ifname)); + ignore_value(virNetDevTapDelete(net->ifname)); + } + } +} + int virBhyveProcessStart(virConnectPtr conn, bhyveConnPtr driver, @@ -167,6 +185,8 @@ virBhyveProcessStart(virConnectPtr conn, ignore_value(virCommandRun(destroy_cmd, NULL)); virCommandFree(destroy_cmd); } + + bhyveNetCleanup(vm); } virCommandFree(load_cmd); @@ -181,7 +201,6 @@ virBhyveProcessStop(bhyveConnPtr driver, virDomainObjPtr vm, virDomainShutoffReason reason ATTRIBUTE_UNUSED) { - size_t i; int ret = -1; virCommandPtr cmd = NULL; @@ -203,17 +222,8 @@ virBhyveProcessStop(bhyveConnPtr driver, vm->def->name, (int)vm->pid); - for (i = 0; i < vm->def->nnets; i++) { - virDomainNetDefPtr net = vm->def->nets[i]; - int actualType = virDomainNetGetActualType(net); - - if (actualType == VIR_DOMAIN_NET_TYPE_BRIDGE) { - ignore_value(virNetDevBridgeRemovePort( - virDomainNetGetActualBridgeName(net), - net->ifname)); - ignore_value(virNetDevTapDelete(net->ifname)); - } - } + /* Cleanup network interfaces */ + bhyveNetCleanup(vm); /* No matter if shutdown was successful or not, we * need to unload the VM */ -- 1.8.4.2
