[libvirt] [PATCH 0/3] Some minor IOThread API adjustments/checks
by John Ferlan 18 Aug '15

18 Aug '15

As a result of the review of a related issue for virDomainAddIOThread it was noted that it's only our implementation for qemu that doesn't want an iothread_id == 0, see: http://www.redhat.com/archives/libvir-list/2015-August/msg00310.html Continued IRC chats with the submittor of that patch discovered some inconsistencies which are dealt with in this patch series... Patch 1 - Remove the iothread_id arg check in virDomainPinIOThread. Since 0 was allowed by the API anyway and left up to the hypervisor. The argument is unsigned - so in reality all that was being checked was 0 - other similar callers work on 'int' values not 'unsigned int'. Patch 2 - Adjust the description in virDomainAddIOThread to remove the "positive non-zero value" and then rework the text to be clearer that it's up to the hypervisor to decide what values are legal and how to handle possible duplication. Patch 3 - Add check in qemu_driver Add/Del IOThread API for the invalid 0 value for iothread_id NOTE: It's not necessary to add a specific illegal argument check for iothread_id = 0 in qemuDomainPinIOThread since both the live and config paths will first search for the iothread_id value and fail if not found in the iothreadid list. I'm not opposed to adding a specific error message if so desired...

[libvirt] [PATCH] qemuDomainRename: Report error if adding domain to domainObj list fails
by Michal Privoznik 18 Aug '15

18 Aug '15

So, domain renaming works like this: new domain name is added into the list of domain objects. Then, domain definition is updated. After that, old domain name is removed from the domain object list.

[libvirt] [PATCH] qemu: Resolve Coverity UNINIT
by John Ferlan 16 Aug '15

16 Aug '15

Coverity complained that 'vm' wasn't initialized before jumping to cleanup: and calling virDomainObjEndAPI if the VIR_STRDUP fails. Rather than initialize vm = NULL, I moved the VIR_STRDUP closer to usage and used endjob for goto.

[libvirt] [PATCH 0/7] qemu: Make it possible to run domains with dirrefent seclabels
by Martin Kletzander 14 Aug '15

14 Aug '15

We offer setting seclabel for the whole domain, but we never fixed the fact that the domain will not be able to even create its monitor socket because the directory is owned by the default preconfigured user and group. Moreover the selinux context can be off as well. So this patch series fixes few preliminary problems and then changes autogenerating so that it creates path per-domain. That way we can start do mains with any seclabels we want without that annoying error message (or similar ones, depends on your configuration): error: Failed to start domain dummy error: internal error: process exited while connecting to monitor: 2015-08-13T15:26:01.474941Z qemu-system-x86_64: -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/dummy.monitor,server,nowait: Failed to unlink socket /var/lib/libvirt/qemu/dummy.monitor: Permission denied The idea is mentioned in this thread in which I tried fixing it pretty badly without thinking it through (feel free to read the patch for your amusement): https://www.redhat.com/archives/libvir-list/2015-February/msg01051.htmlA One thing to note here is that tests for patch 5/7 are in a separate patch 6/7 and only minimal. We can also use qemuxml2argvtest to test for the same thing and indeed that is patch 7/7 that I haven't sent. I will send it if anyone wants to have that been done as well, but I believe the qemuxml2argvtest can be left as it currently is because the patch itself has around 350KiB. It's also enough if you just tell me in the review that I should squash it in the previous commit (which I don't suppose anyone will do). Or another idea, I made it available on my github: https://github.com/nertpinx/libvirt.git (branch bz1146886) Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1146886 Martin Kletzander (7):

[libvirt] [PATCH] Inherit namespace feature 2
by ik.nitk 14 Aug '15

14 Aug '15

This patch adds feature for lxc containers to inherit namespaces. This is very similar to what lxc-tools or docker provides. Look for "man lxc-start" and you will find that you can pass command args as [ --share-[net|ipc|uts] name|pid ]. Or check out docker networking option in which you can give --net=container:NAME_or_ID as an option for sharing namespace. >From this patch you can add extra libvirt option to share namespace in following way. <lxc:namespace> <lxc:sharenet type='netns' value='red'/> <lxc:shareipc type='pid' value='12345'/> <lxc:shareuts type='name' value='container1'/> </lxc:namespace> The netns option is specific to sharenet. It can be used to inherit from existing network namespace.w --- docs/drvlxc.html.in | 21 +++++ docs/schemas/domaincommon.rng | 42 +++++++++ src/Makefile.am | 2 +- src/lxc/lxc_conf.c | 2 +- src/lxc/lxc_conf.h | 15 ++++ src/lxc/lxc_container.c | 145 ++++++++++++++++++++++++++++-- src/lxc/lxc_container.h | 1 + src/lxc/lxc_controller.c | 42 ++++++++- src/lxc/lxc_domain.c | 164 +++++++++++++++++++++++++++++++++- src/lxc/lxc_domain.h | 1 + src/lxc/lxc_process.c | 111 +++++++++++++++++++++++ tests/lxcxml2xmldata/lxc-sharenet.xml | 33 +++++++ tests/lxcxml2xmltest.c | 1 + 13 files changed, 570 insertions(+), 10 deletions(-) create mode 100644 tests/lxcxml2xmldata/lxc-sharenet.xml diff --git a/docs/drvlxc.html.in b/docs/drvlxc.html.in index a094bd9..d6c57c4 100644 --- a/docs/drvlxc.html.in +++ b/docs/drvlxc.html.in @@ -590,6 +590,27 @@ Note that allowing capabilities that are normally dropped by default can serious affect the security of the container and the host. </p> +<h2><a name="share">Inherit namespaces</a></h2> + +<p> +Libvirt allows you to inherit the namespace from container/process just like lxc tools +or docker provides to share the network namespace.

[libvirt] [PATCH v4 0/5] domainRename API implementation
by Tomas Meszaros 14 Aug '15

14 Aug '15

This is an effort to implement domain rename API. Presented patch series consists of the following: virDomainRename API implementation for qemu, implementation of the virsh command domrename and the additional support code. The idea behind this endeavor is to provide convenient and safe way to rename a domain. Instead of the: virsh dumpxml domain > domain.xml (change domain name in domain.xml) virsh undefine domain virsh define domain.xml user can simply type: virsh domrename foo bar or call virDomainRename() API and domain "foo" will be renamed to "bar". We currently support only renaming inactive domains without snapshots. Renaming procedure takes care of domain log, config, guest agent path and should be able to recover in case of failure. I've been working on this functionality in collaboration with Michal Privoznik who is my mentor during the GSoC 2015. If you have any questions, ideas or criticism feel free to join the discussion. v2: - removed guest agent path rename code - removed rename permission - added code for emitting undefined+renamed event for the old domain v3: - removed domain rename permission - fixed virDomainRename doc comment - added @flags parameter to the virDomainRename API v4: - removed ATTRIBUTE_UNUSED from the @flags parameter - added virCheckFlags() call - added flags to the remote_domain_rename_args Tomas Meszaros (5): Introduce virDomainRename API virsh: Implement "domrename" command domain_conf: Introducde virDomainObjListRenameAddNew() & virDomainObjListRenameRemove() Introduce new VIR_DOMAIN_EVENT_DEFINED_RENAMED event qemu: Implement virDomainRename examples/object-events/event-test.c | 4 + include/libvirt/libvirt-domain.h | 6 ++ src/conf/domain_conf.c | 35 +++++++++ src/conf/domain_conf.h | 5 ++ src/driver-hypervisor.h | 6 ++ src/libvirt-domain.c | 35 +++++++++ src/libvirt_private.syms | 2 + src/libvirt_public.syms | 5 ++ src/qemu/qemu_driver.c | 147 ++++++++++++++++++++++++++++++++++++ src/remote/remote_driver.c | 1 + src/remote/remote_protocol.x | 18 ++++- src/remote_protocol-structs | 9 +++ tools/virsh-domain.c | 63 +++++++++++++++- tools/virsh.pod | 7 ++ 14 files changed, 340 insertions(+), 3 deletions(-) -- 2.1.0

[libvirt] Entering freeze for libvirt-1.2.17
by Daniel Veillard 13 Aug '15

Following discussions on Friday, I applied the patches to deactivate the subset of Admin APIs and revert from 1.3.0 to 1.2.17. I then tagged in git and pushed signed tarballs and rpms to the usual place: ftp://libvirt.org/pub/libvirt/ I didn't run my usual tests on that one, my infra is in flux, so even more reasons for people to give it a try :-) I'm likely to make a candidate release 2 on Tuesday and if all goes well we can push 1.2.17 on Thursday, thanks, Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

Hi, [please Cc me any reply, I'm not subscribed to libvir-list.] it was reported [1] to Ubuntu that virt-aa-helper blocks access to the OVMF files needed to boot UEFI virtual machines in QEMU. After I've confirmed that on Debian sid, Jamie Strandboge suggested a fix. I've successfully tested in my environment (applied on top of 1.2.18) so I'm forwarding it here.

[libvirt] [PATCH] Drive hot-unplug: reliable parsing of HMP results
by Frank Schreuder 12 Aug '15

12 Aug '15

Hot-unplugging a disk from a guest that supports hot-unplugging generates an error in the libvirt log when running QEMU with the "-msg timestamp=on" flag. 2015-08-06 10:48:59.945+0000: 11662: error : qemuMonitorTextDriveDel:2594 : operation failed: deleting drive-virtio-disk4 drive failed: 2015-08-06T10:48:59.945058Z Device 'drive-virtio-disk4' not found This error is caused because the HMP results are getting prefixed with a timestamp. Parsing the output is not reliable with STRPREFIX as the results can be prefixed with a timestamp. Using strstr ensures that parsing the output works whether the results are prefixed or not.

[libvirt] [PATCH] domain: Fix crash if trying to live update disk <serial>
by Cole Robinson 12 Aug '15

12 Aug '15

If you pass <disk><serial> XML to UpdateDevice, and the original device didn't have a <serial> block, libvirtd crashes trying to read the original NULL serial string. Use _NULLABLE string comparisons to avoid the crash. A couple other properties needed the change too. --- src/conf/domain_conf.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index fd0450f..f1e02e3 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -5871,28 +5871,28 @@ virDomainDiskDiffersSourceOnly(virDomainDiskDefPtr disk, CHECK_EQ(transient, "transient", true); - if (disk->serial && STRNEQ(disk->serial, orig_disk->serial)) { + if (disk->serial && STRNEQ_NULLABLE(disk->serial, orig_disk->serial)) { virReportError(VIR_ERR_OPERATION_UNSUPPORTED, _("cannot modify field '%s' of the disk"), "serial"); return false; } - if (disk->wwn && STRNEQ(disk->wwn, orig_disk->wwn)) { + if (disk->wwn && STRNEQ_NULLABLE(disk->wwn, orig_disk->wwn)) { virReportError(VIR_ERR_OPERATION_UNSUPPORTED, _("cannot modify field '%s' of the disk"), "wwn"); return false; } - if (disk->vendor && STRNEQ(disk->vendor, orig_disk->vendor)) { + if (disk->vendor && STRNEQ_NULLABLE(disk->vendor, orig_disk->vendor)) { virReportError(VIR_ERR_OPERATION_UNSUPPORTED, _("cannot modify field '%s' of the disk"), "vendor"); return false; } - if (disk->product && STRNEQ(disk->product, orig_disk->product)) { + if (disk->product && STRNEQ_NULLABLE(disk->product, orig_disk->product)) { virReportError(VIR_ERR_OPERATION_UNSUPPORTED, _("cannot modify field '%s' of the disk"), "product"); -- 2.4.3

[libvirt] [PATCH v5 0/4] qemu: Allow PCI virtio on ARM "virt" machine
by Pavel Fedin 12 Aug '15

12 Aug '15

Virt machine in qemu since v2.3.0 has PCI generic host controller, and can use PCI devices. This provides performance improvement as well as vhost-net with irqfd support for virtio-net. However libvirt currently does not allow ARM virt machine to have PCI devices. This patchset adds the necessary support. Changes since v4: - Rebased onto current master - Added possibility to plug virtio-net-pci adapter directly into PCIe bus. This is necessary for irqfds to work in qemu. Changes since v3: - Capability is based not on qemu version but on support of "gpex-pcihost" device by qemu - Added a workaround, allowing to pass "make check". The problem is that test suite does not build capabilities cache. Unfortunately this means that correct unit-test for the new functionality currently cannot be written. Test suite framework needs to be improved. Changes since v2: Complete rework, use different approach - Correctly model PCI Express bus on the machine. It is now possible to explicitly specify <address-type='pci'> with attributes. This allows to attach not only virtio, but any other PCI device to the model. - Default is not changed and still mmio, for backwards compatibility with existing installations. PCI bus has to be explicitly specified. - Check for the capability in correct place, in v2 it actually did not work Changes since v1: - Added capability based on qemu version number - Recognize also "virt-" prefix Pavel Fedin (4): qemu: Introduce QEMU_CAPS_OBJECT_GPEX Add PCI-Express root to ARM virt machine Build correct command line for PCI NICs on ARM Allow to plug virtio-net-pci into PCIe slot src/qemu/qemu_capabilities.c | 10 ++++++++++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 11 ++++++++++- src/qemu/qemu_domain.c | 17 +++++++++++++---- 4 files changed, 34 insertions(+), 5 deletions(-) -- 1.9.5.msysgit.0

[libvirt] [PATCH] qemu: fix qemuDomainSupportsPCI() for ARM machines of "virt" machinetype
by Laine Stump 11 Aug '15

11 Aug '15

Commit e8d5517 updated the domain post-parse to automatically add pcie-root et al for certain ARM "virt" machinetypes, but didn't update the function qemuDomainSupportsPCI() which is called later on when we are auto-assigning PCI addresses and default settings for the PCI controller <model> and <target> attributes. The result was that PCI addresses weren't assigned, and the controllers didn't have their attribute default values set, leading to an error when the domain was started, e.g.: internal error: autogenerated dmi-to-pci-bridge options not set This patch duplicates the check made in the earlier patch, so that PCI address auto-assignment and target/model default values will be set. --- The example Cole gave in his email reporting this bug is fixed by this patch. src/qemu/qemu_command.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index ae03618..84cbfe1 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -1742,7 +1742,7 @@ qemuCollectPCIAddress(virDomainDefPtr def ATTRIBUTE_UNUSED, } static bool -qemuDomainSupportsPCI(virDomainDefPtr def) +qemuDomainSupportsPCI(virDomainDefPtr def, virQEMUCapsPtr qemuCaps) { if ((def->os.arch != VIR_ARCH_ARMV7L) && (def->os.arch != VIR_ARCH_AARCH64)) return true; @@ -1750,6 +1750,11 @@ qemuDomainSupportsPCI(virDomainDefPtr def) if (STREQ(def->os.machine, "versatilepb")) return true; + if ((STREQ(def->os.machine, "virt") || + STRPREFIX(def->os.machine, "virt-")) && + virQEMUCapsGet(qemuCaps, QEMU_CAPS_OBJECT_GPEX)) + return true; + return false; } @@ -2267,7 +2272,7 @@ qemuDomainAssignPCIAddresses(virDomainDefPtr def, if (!(addrs = qemuDomainPCIAddressSetCreate(def, nbuses, false))) goto cleanup; - if (qemuDomainSupportsPCI(def)) { + if (qemuDomainSupportsPCI(def, qemuCaps)) { if (qemuValidateDevicePCISlotsChipsets(def, qemuCaps, addrs) < 0) goto cleanup; -- 2.1.0

[libvirt] [PATCHv2] util: don't overwrite stack when getting ethtool gfeatures
by Laine Stump 11 Aug '15

11 Aug '15

This fixes the crash described here: https://www.redhat.com/archives/libvir-list/2015-August/msg00162.html In short, we were calling ioctl(SIOCETHTOOL) pointing to a too-short object that was a local on the stack, resulting in the memory past the end of the object being overwritten. This was because the struct used by the ETHTOOL_GFEATURES command of SIOCETHTOOL ends with a 0-length array, but we were telling ethtool that it could use 2 elements on the array. The fix is to allocate the necessary memory with VIR_ALLOC_VAR(), including the extra length needed for a 2 element array at the end. --- V2 difference: eliminate all the other cleanups that were in V1, just fix the crash.

[libvirt] [PATCH] util: fix virNetDevSendEthtoolIoctl() and its callers
by Laine Stump 11 Aug '15

11 Aug '15

This started out as a fix for a crash reported in IRC and on libvir-list: https://www.redhat.com/archives/libvir-list/2015-August/msg00162.html but as I examined the existing code I found so many nits to pick that I just did them all. The most important fix here is that virNetDevGetFeatures was creating a struct ethtool_gfeatures object as a local on the stack and, although the struct is defined with 0 elements in its features array, we were telling the ethtool ioctl that we had made space for 2 elements. This led to a crash, as outlined in the email above. The fix for this is to allocate the memory for the ethtool_gfeatures object using VIR_ALLOC_N to a char*, giving it the length: sizeof(ethtool_gfeatures) + (2 * sizeof(ethtool_get_features_block) because VIR_ALLOC_N is a macro and fails when you try to typecast a pointer to char* within the invocation, I made a union that has both a char* and an ethtool_gfeatures*, and used the char* of the union for VIR_ALLOC_N, and the other for everything else. Beyond that crash fixer, the following fixups were made to the hierarchy of functions between virNetDevGetFeatures() and virNetDevSendEthtoolIoctl(): * macros used to examine the gfeatures bits were renamed from FEATURE_* to GFEATURE_* virNetDevSentEthtoolIoctl(): * no need to initialize sock to -1, since it is always set at the top of the function. * remove VIR_DEBUG log (and subsequent *skipping* of error log!) when errno is EPERM, EINVAL or EOPNOTSUPP. If one of those errors were ever encountered, this would have been *very* problematic, as it would have led to one of those situations where virsh reports "an error was encountered but the cause is unknown" (or whatever the message is when we have an error but no log message). * always call VIR_FORCE_CLOSE(sock) since we know that sock is either a valid fd, or else -1 (which VIR_FORCE_CLOSE() will skip). virNetDevFeatureAvailable() * simplify it - no need for ret. * follow libvirt convention of checking for "bobLobLaw(lawblog) < 0" instead of "!bobLobLaw(lawblog)". virNetDevGFeatureAvailable() * eliminate this function, as it was ill-conceived (it really was only checking for one gfeature (TX_UDP_TNL), not *any* gfeature. virNetDevGetFeatures() * move all data tables (struct elem) out of the function so that they will be statics instead of taking up space on the stack. * remove pointless/incorrect initialization of i = -1. * remove unnecessary static initialization of struct ethtool_value cmd * put struct ethtool_gfeatures into a union with a char* as described above * use libvirt convention of checking return from virNetDevFeatureAvailable() < 0, instead of "!virNetDevFeatureAvailable()", and immediately return to caller with an error when virNetDevFeatureAvailable() returns an error (previously it was ignored). * remove superfluous size_t j, and just re-use i instead. * runtime allocation/free of proper size object for ethtoolfeatures as described above. * directly call virNetDevSentEthtoolIoctl() instead of now defunct virNetDevGFeatureAvailable(). === NB: This patch does *not* attempt to determine the proper number of elements for the gfeature array at runtime, as proposed in this patch: https://www.redhat.com/archives/libvir-list/2015-August/msg00263.html since that wasn't the cause of the crash. I'll leave it up to Moshe to repost that patch rebased around this one (or whatever ends up being pushed) if he thinks there is value to it. Also - as I mentioned in earlier mail in response to the crash, I noticed when looking into the gfeatures ethtool code that it looks to me like TX_UDP_TNL should actually be 26 rather than 25, but I may be missing something. Moshe - can you either confirm or deny that?

[libvirt] [PATCH] network: validate network NAT range
by Laine Stump 11 Aug '15

11 Aug '15

This patch modifies virSocketAddrGetRange() to function properly when the containing network/prefix of the address range isn't known, for example in the case of the NAT range of a virtual network (since it is a range of addresses on the *host*, not within the network itself). We then take advantage of this new functionality to validate the NAT range of a virtual network. Extra test cases are also added to verify that virSocketAddrGetRange() works properly in both positive and negative cases when the network pointer is NULL. This is the *real* fix for: https://bugzilla.redhat.com/show_bug.cgi?id=985653 Commits 1e334a and 48e8b9 had earlier been pushed as fixes for that bug, but I had neglected to read the report carefully, so instead of fixing validation for the NAT range, I had fixed validation for the DHCP range. sigh. --- The changes to virSocketAddrGetRange() *look* like they are extensive, but really they almost completely consist of: 1) reordering and reindenting some of the checks so that they are only executed when we have a valid network address 2) modifying the error messages that could occur when there isn't a valid network so that they don't attempt to use the network address or prefix. src/conf/network_conf.c | 4 ++ src/util/virsocketaddr.c | 168 +++++++++++++++++++++++++---------------------- tests/sockettest.c | 46 ++++++++++++- 3 files changed, 136 insertions(+), 82 deletions(-) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index f77af15..b8d918c 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -1731,6 +1731,10 @@ virNetworkForwardNatDefParseXML(const char *networkName, goto cleanup; } + /* verify that start <= end */ + if (virSocketAddrGetRange(&def->addr.start, &def->addr.end, NULL, 0) < 0) + goto cleanup; + /* ports for SNAT and MASQUERADE */ nNatPorts = virXPathNodeSet("./port", ctxt, &natPortNodes); if (nNatPorts < 0) { diff --git a/src/util/virsocketaddr.c b/src/util/virsocketaddr.c index 81539b3..900aa5b 100644 --- a/src/util/virsocketaddr.c +++ b/src/util/virsocketaddr.c @@ -628,126 +628,136 @@ virSocketAddrGetRange(virSocketAddrPtr start, virSocketAddrPtr end, virSocketAddr netmask; char *startStr = NULL, *endStr = NULL, *netStr = NULL; - if (start == NULL || end == NULL || network == NULL) { + if (start == NULL || end == NULL) { virReportError(VIR_ERR_INTERNAL_ERROR, - _("NULL argument - %p %p %p"), start, end, network); + _("NULL argument - %p %p"), start, end); goto error; } startStr = virSocketAddrFormat(start); endStr = virSocketAddrFormat(end); - netStr = virSocketAddrFormat(network); - if (!(startStr && endStr && netStr)) + if (!startStr || !endStr) goto error; /*error already reported */ - if (VIR_SOCKET_ADDR_FAMILY(start) != VIR_SOCKET_ADDR_FAMILY(end) || - VIR_SOCKET_ADDR_FAMILY(start) != VIR_SOCKET_ADDR_FAMILY(network)) { + if (VIR_SOCKET_ADDR_FAMILY(start) != VIR_SOCKET_ADDR_FAMILY(end)) { virReportError(VIR_ERR_INTERNAL_ERROR, - _("mismatch of address family in " - "range %s - %s for network %s"), - startStr, endStr, netStr); + _("mismatch of address family in range %s - %s"), + startStr, endStr); goto error; } - if (prefix < 0 || - virSocketAddrPrefixToNetmask(prefix, &netmask, - VIR_SOCKET_ADDR_FAMILY(network)) < 0) { - virReportError(VIR_ERR_INTERNAL_ERROR, - _("bad prefix %d for network %s when " - " checking range %s - %s"), - prefix, netStr, startStr, endStr); - goto error; - } - - /* both start and end of range need to be in the same network as - * "network" - */ - if (virSocketAddrCheckNetmask(start, network, &netmask) <= 0 || - virSocketAddrCheckNetmask(end, network, &netmask) <= 0) { - virReportError(VIR_ERR_INTERNAL_ERROR, - _("range %s - %s is not entirely within " - "network %s/%d"), - startStr, endStr, netStr, prefix); - goto error; - } - - if (VIR_SOCKET_ADDR_IS_FAMILY(start, AF_INET)) { - virSocketAddrIPv4 t1, t2; - virSocketAddr netaddr, broadcast; + if (network) { + /* some checks can only be done if we have details of the + * network the range should be within + */ + if (!(netStr = virSocketAddrFormat(network))) + goto error; - if (virSocketAddrBroadcast(network, &netmask, &broadcast) < 0 || - virSocketAddrMask(network, &netmask, &netaddr) < 0) { + if (VIR_SOCKET_ADDR_FAMILY(start) != VIR_SOCKET_ADDR_FAMILY(network)) { virReportError(VIR_ERR_INTERNAL_ERROR, - _("failed to construct broadcast or network " - "address for network %s/%d"), - netStr, prefix); + _("mismatch of address family in " + "range %s - %s for network %s"), + startStr, endStr, netStr); goto error; } - /* Don't allow the start of the range to be the network - * address (usually "...0") or the end of the range to be the - * broadcast address (usually "...255").

[libvirt] [PATCH 0/9] Add missing QoS implementation

The first patch is unrelated to the rest, but I have it on the same branch. The patches 2..5 fix a daemon crasher (since domain_write ACL is required, I'm not going through libvirt-security). Then, since after patch 5 we have nearly everything prepared, patches 6..9 implement new feature: setting @floor live on domain interfaces.

[libvirt] [PATCH v2 0/5] domainRename API implementation
by Tomas Meszaros 10 Aug '15

10 Aug '15

s is an effort to implement domain rename API. Presented patch series consists of the following: virDomainRename API implementation for qemu, implementation of the virsh command domrename and the additional support code. The idea behind this endeavor is to provide convenient and safe way to rename a domain. Instead of the: virsh dumpxml domain > domain.xml (change domain name in domain.xml) virsh undefine domain virsh define domain.xml user can simply type: virsh domrename foo bar or call virDomainRename() API and domain "foo" will be renamed to "bar". We currently support only renaming inactive domains without snapshots. Renaming procedure takes care of domain log, config, guest agent path and should be able to recover in case of failure. I've been working on this functionality in collaboration with Michal Privoznik who is my mentor during the GSoC 2015. If you have any questions, ideas or criticism feel free to join the discussion. v2: - removed guest agent path rename code - removed rename permission - added code for emitting undefined+renamed event for the old domain Tomas Meszaros (5): Introduce virDomainRename API virsh: Implement "domrename" command domain_conf: Introducde virDomainObjListRenameAddNew() & virDomainObjListRenameRemove() Introduce new VIR_DOMAIN_EVENT_DEFINED_RENAMED event qemu: Implement virDomainRename examples/object-events/event-test.c | 4 + include/libvirt/libvirt-domain.h | 4 + src/access/viraccessperm.c | 3 +- src/access/viraccessperm.h | 6 ++ src/conf/domain_conf.c | 35 +++++++++ src/conf/domain_conf.h | 5 ++ src/driver-hypervisor.h | 5 ++ src/libvirt-domain.c | 31 ++++++++ src/libvirt_private.syms | 2 + src/libvirt_public.syms | 5 ++ src/qemu/qemu_driver.c | 144 ++++++++++++++++++++++++++++++++++++ src/remote/remote_driver.c | 1 + src/remote/remote_protocol.x | 17 ++++- src/remote_protocol-structs | 8 ++ tools/virsh-domain.c | 63 +++++++++++++++- tools/virsh.pod | 7 ++ 16 files changed, 336 insertions(+), 4 deletions(-) -- 2.1.0

[libvirt] [PATCHv3 00/13] Add new PCIe controllers
by Laine Stump 10 Aug '15

10 Aug '15

Since the first 3 patches of V2 were ACKed and uncontroversial, I fixed the small problems pointed out in the reviews and pushed them. Thus, Patches 01-13 here correspond to Patches 04-17 in V2. Most of these patches were already ACKed in V2 (pending my making small fixes pointed out in review), but the main things that need review are: 1) changing of model name from a char* to an enum in Patch 01, and corresponding blowback in patches 02, 07, 10, and 13 2) range checking of chassisNr in Patch 03 and chassis+port in patch 06. 3) check for duplicate <model> in patch 01, and duplicate <target> in patch 03. I did add one new negative test, and reworded some documentation, but I'm about to go mostly offline for 10 days, and would rather not have these patches bitrotting during that time if they are okay other than that. (also, I see both of those tasks as having no practical end, but do give my word to add more to both in later followups). If by chance everything is ACKed before DV freezes for RC1, but after I'm already offline (which will happen Sunday morning U.S. east coast time), I would appreciate if the reviewer could push the patches so they'll get the RC testing and be in the 1.2.18 release. (If not, I'll take care of it when I return). P.S. I ran "git rebase -i master -x "make -j8 check && make -j8 syntax-check" before sending.

[libvirt] [PATCH] virNetDevBandwidthParseRate: Reject negative values
by Michal Privoznik 10 Aug '15

https://bugzilla.redhat.com/show_bug.cgi?id=1022292 The following XML really does not make any sense: <inbound average="-1" burst="-2" peak="-3" floor="-4"/> There can't be a negative packet rate. Well, so far we haven't assigned any meaning to it. So reject it unless users harm themselves, because otherwise we turn the negative numbers into really big values.

[libvirt] [PATCH v3] rpc: Remove keepalive_required option
by Martin Kletzander 10 Aug '15

10 Aug '15

Since its introduction in 2011 (particularly in commit f4324e329275), the option doesn't work. It just effectively disables all incoming connections. That's because the client private data that contain the 'keepalive_supported' boolean, are initialized to zeroes so the bool is false and the only other place where the bool is used is when checking whether the client supports keepalive. Thus, according to the server, no client supports keepalive. Removing this instead of fixing it is better because a) apparently nobody ever tried it since 2011 (4 years without one month) and b) we cannot know whether the client supports keepalive until we get a ping or pong keepalive packet. And that won't happen untile after we dispatched the ConnectOpen call. Another two reasons would be c) the keepalive_required was tracked on the server level, but keepalive_supported was in private data of the client as well as the check that was made in the remote layer, thus making all other instances of virNetServer miss this feature unless they all implemented it for themselves and d) we can always add it back in case there is a request and a use-case for it.

[libvirt] [PATCH 0/2] Added waiting for DAD to finish for bridge address.
by Maxim Perevedentsev 10 Aug '15

10 Aug '15

This is a fix for commit db488c79173b240459c7754f38c3c6af9b432970 dnsmasq main process which is relied on when waiting for DAD to complete exits without actually waiting for DAD. This is dnsmasq daemon's task. It seems to be a race that DAD finished before dnsmasq main process exited. The above commit needs the execution to block until DAD finishes for bridge IPv6 address because then it closes dummy tap device. Thus we need to ensure this ourselves. So we periodically poll the kernel using netlink and check whether there are any IPv6 addresses assigned to bridge which have 'tentative' state. After DAD is finished, execution continues. I guess that is what dnsmasq was assumed to do. We use netlink to dump information about existing IPv6 addresses. Netlink's response is a multi-part message. Unfortunately, the current implementation of virNetlink treats such messages as faulty and throws an error. So the patch 2/2 adds multi-part nelink response support.

[libvirt] [PATCH] qemu: fail on attempts to use <filterref> for non-tap network connections
by Laine Stump 10 Aug '15

10 Aug '15

nwfilter uses iptables and ebtables, which only work properly on tap-based network connections (*not* on macvtap, for example), but we just ignore any <filterref> elements for other types of networks, potentially giving users a false sense of security. This patch checks the network type and fails/logs an error if any domain <interface> has a <filterref> when the connection isn't using a tap device.

[libvirt] [PATCH] virt drivers: show used memory as 0 when domain is inactive
by Jim Fehlig 10 Aug '15

Commit 1ce7c1d2 changed domainGetInfo to set virDomainInfoPtr->memory to 0 when domain is inactive, but only did this for the LXC and QEMU drivers. Make a similar change to the other virt drivers so they all behave the same.

[libvirt] [PATCH] virDomainCoreDumpWithFormat: Mention enum for @dumpformat
by Michal Privoznik 10 Aug '15

10 Aug '15

So the API takes @dumpformat argument. This is what makes it special when compared to virDomainCoreDump. The argument is there so that users can choose the format of resulting core dump file. And to ease them the choosing process we even have an enum with supported values across all the hypervisors. But we don't mention the enum in the function description anywhere. Fix it!

[libvirt] [PATCHv2] conf: more useful error message when pci function is out of range
by Laine Stump 09 Aug '15

09 Aug '15

If a pci address had a function number out of range, the error message would be: Insufficient specification for PCI address which is logged by virDevicePCIAddressParseXML() after virDevicePCIAddressIsValid returns a failure. This patch enhances virDevicePCIAddressIsValid() to optionally report the error itself (since it is the place that decides which part of the address is "invalid"), and uses that feature when calling from virDevicePCIAddressParseXML(), so that the error will be more useful, e.g.: Invalid PCI address function=0x8, must be <= 7 Previously, virDevicePCIAddressIsValid didn't check for the theoretical limits of domain or bus, only for slot or function. While adding log messages, we also correct that ommission. (The RNG for PCI addresses already enforces this limit, which by the way means that we can't add any negative tests for this - as far as I know our domainschematest has no provisions for passing XML that is supposed to fail). Note that virDevicePCIAddressIsValid() can only check against the absolute maximum attribute values for *any* possible PCI controller, not for the actual maximums of the specific controller that this device is attaching to; fortunately there is later more specific validation for guest-side PCI addresses when building the set of assigned PCI addresses. For host-side PCI addresses (e.g. for <hostdev> and for network device pools), we rely on the error that will be logged when it is found that the device doesn't actually exist. This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1004596 --- Change from V1: V1 simply removed the validation from virDevicePCIAddressParseXML() in favor of allowing things later in the parse process to figure out the out-of-bounds conditions, but jtomko pointed out that there are other uses of virDevicePCIAddressParseXML() aside from the guest-side PCI addresses of devices, and that the other uses relied on the one validation check in virDevicePCIAddressParseXML() to make sure the address was sensible. So instead of simply removing the check, I had to make it smarter about what it logged. In the process, I added checks for max domain and bus. src/conf/device_conf.c | 52 +++++++++++++++++++++++++++++++++++++++++--------- src/conf/device_conf.h | 5 +++-- src/conf/domain_conf.c | 2 +- 3 files changed, 47 insertions(+), 12 deletions(-) diff --git a/src/conf/device_conf.c b/src/conf/device_conf.c index e7b7957..4e15d38 100644 --- a/src/conf/device_conf.c +++ b/src/conf/device_conf.c @@ -1,7 +1,7 @@ /* * device_conf.c: device XML handling * - * Copyright (C) 2006-2012 Red Hat, Inc. + * Copyright (C) 2006-2015 Red Hat, Inc. * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public @@ -55,12 +55,49 @@ VIR_ENUM_IMPL(virNetDevFeature, "rdma", "txudptnl") -int virDevicePCIAddressIsValid(virDevicePCIAddressPtr addr) +int virDevicePCIAddressIsValid(virDevicePCIAddressPtr addr, + bool report) { - /* PCI bus has 32 slots and 8 functions per slot */ - if (addr->slot >= 32 || addr->function >= 8) + if (addr->domain > 0xFFFF) { + if (report) + virReportError(VIR_ERR_XML_ERROR, + _("Invalid PCI address domain='0x%x', " + "must be <= 0xFFFF"), + addr->domain); + return 0; + } + if (addr->bus > 0xFF) { + if (report) + virReportError(VIR_ERR_XML_ERROR, + _("Invalid PCI address bus='0x%x', " + "must be <= 0xFF"), + addr->bus); return 0; - return addr->domain || addr->bus || addr->slot; + } + if (addr->slot > 0x1F) { + if (report) + virReportError(VIR_ERR_XML_ERROR, + _("Invalid PCI address slot='0x%x', " + "must be <= 0x1F"), + addr->slot); + return 0; + } + if (addr->function > 7) { + if (report) + virReportError(VIR_ERR_XML_ERROR, + _("Invalid PCI address function=0x%x, " + "must be <= 7"), + addr->function); + return 0; + } + if (!(addr->domain || addr->bus || addr->slot)) { + if (report) + virReportError(VIR_ERR_XML_ERROR, "%s", + _("Invalid PCI address 0000:00:00, at least " + "one of domain, bus, or slot must be > 0")); + return 0; + } + return 1; } @@ -115,11 +152,8 @@ virDevicePCIAddressParseXML(xmlNodePtr node, goto cleanup; } - if (!virDevicePCIAddressIsValid(addr)) { - virReportError(VIR_ERR_INTERNAL_ERROR, "%s", - _("Insufficient specification for PCI address")); + if (!virDevicePCIAddressIsValid(addr, true)) goto cleanup; - } ret = 0; diff --git a/src/conf/device_conf.h b/src/conf/device_conf.h index 40a2b3d..85ce40f 100644 --- a/src/conf/device_conf.h +++ b/src/conf/device_conf.h @@ -1,7 +1,7 @@ /* * device_conf.h: device XML handling entry points * - * Copyright (C) 2006-2012 Red Hat, Inc. + * Copyright (C) 2006-2012, 2014-2015 Red Hat, Inc. * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public @@ -81,7 +81,8 @@ typedef enum { VIR_ENUM_DECL(virNetDevFeature) -int virDevicePCIAddressIsValid(virDevicePCIAddressPtr addr); +int virDevicePCIAddressIsValid(virDevicePCIAddressPtr addr, + bool report); int virDevicePCIAddressParseXML(xmlNodePtr node, virDevicePCIAddressPtr addr); diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 8a89b9a..5142201 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -3133,7 +3133,7 @@ int virDomainDeviceAddressIsValid(virDomainDeviceInfoPtr info, switch (info->type) { case VIR_DOMAIN_DEVICE_ADDRESS_TYPE_PCI: - return virDevicePCIAddressIsValid(&info->addr.pci); + return virDevicePCIAddressIsValid(&info->addr.pci, false); case VIR_DOMAIN_DEVICE_ADDRESS_TYPE_DRIVE: return 1; -- 2.1.0

[libvirt] [PATCH] Inherit namespace feature

This patch adds feature for lxc containers to inherit namespaces. This is very similar to what lxc-tools or docker provides.

[libvirt] [PATCH 00/18] cpu: Fix and improve the ppc64 driver
by Andrea Bolognani 07 Aug '15

07 Aug '15

This series depends on [PATCH 0/4] cpu: Rename {powerpc,ppc} => ppc64 which has been already ACKed[1] and is pending upload. Patches 1-11 are fixes and cleanups that don't introduce any new feature in the driver and just lay the groundwork for the second part of the series. Patches 12-18 rework the driver and add some test cases to cover both existing an new features. Cheers.

[libvirt] [PATCH] virNetDevBandwidthParseRate: Reject negative values
by Michal Privoznik 07 Aug '15

07 Aug '15

https://bugzilla.redhat.com/show_bug.cgi?id=1022292 The following XML really does not make any sense: <inbound average="-1" burst="-2" peak="-3" floor="-4"/> There can't be a negative packet rate. Well, so far we haven't assigned any meaning to it. So reject it unless users harm themselves, because otherwise we turn the negative numbers into really big values.

[libvirt] [PATCH] qemu: Fix reporting of physical capacity for block devices
by Peter Krempa 07 Aug '15

07 Aug '15

Qemu reports physical size 0 for block devices. As 15fa84acbb55ebfee6a4 changed the behavior of qemuDomainGetBlockInfo to just query the monitor this created a regression since we didn't report the size correctly any more. This patch adds code to refresh the physical size of a block device by opening it and seeking to the end and uses it both in qemuDomainGetBlockInfo and also in qemuDomainGetStatsOneBlock that was broken since it was introduced in this respect.

[libvirt] Reproducible live disk detach bug
by Frank Schreuder 06 Aug '15

Hey guys, I am currently running into a reproducible libvirt bug when I detach a disk from a running VM using libvirt 1.2.18 and qemu 2.3.0. I can attach a disk to a running VM without any problems. During the attach operation I don't create a disk alias name, which results in libvirt generating an unique alias. Using virsh dumpxml I get the following output(snippet): <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source file='/var/local/mnt/test-storage/test-storage.raw'/> <backingStore/> <target dev='vde' bus='virtio'/> <iotune> <read_bytes_sec>94371840</read_bytes_sec> <write_bytes_sec>31457280</write_bytes_sec> <read_iops_sec>1000</read_iops_sec> <write_iops_sec>200</write_iops_sec> </iotune> <alias name='virtio-disk4'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/> </disk> As you can see, libvirt generates 'virtio-disk4' as an alias. But as soon as I try to detach the disk from the running VM, I will receive the following two errors in my libvirt log: 2015-08-06 10:48:59.943+0000: 11657: warning : qemuMonitorJSONHandleDeviceDeleted:939 : missing device in device deleted event 2015-08-06 10:48:59.945+0000: 11662: error : qemuMonitorTextDriveDel:2594 : operation failed: deleting drive-virtio-disk4 drive failed: 2015-08-06T10:48:59.945058Z Device 'drive-virtio-disk4' not found Apparently libvirt tries to detach the disk with a drive- prefix, which doesn't exist? The drive seems to detach correctly though. I hope somebody with more extensive knowledge about libvirt can help me solve this issue. If more information is needed, feel free to contact me.

The drive seems to detach correctly though. I hope somebody with more extensive knowledge about libvirt can help me solve this issue. If more information is needed, feel free to contact me.

[libvirt] [PATCH] qemu: Forbid image pre-creation for non-shared storage migration
by Peter Krempa 05 Aug '15

05 Aug '15

Libvirt doesn't reliably know the location of the backing chain when pre-creating images for non-shared migration. This isn't a problem for full copy, but incremental copy requires the information. Forbid pre-creating the image in cases where incremental migration is required. This limitation can perhaps be lifted once libvirt will fully support loading of backing chain information from the XML.

[libvirt] [PATCH 0/5] domainRename API implementation
by Tomas Meszaros 05 Aug '15

05 Aug '15

This is an effort to implement domain rename API. Presented patch series consists of the following: virDomainRename API implementation for qemu, implementation of the virsh command domrename and the additional support code. The idea behind this endeavor is to provide convenient and safe way to rename a domain. Instead of the: virsh dumpxml domain > domain.xml (change domain name in domain.xml) virsh undefine domain virsh define domain.xml user can simply type: virsh domrename foo bar or call virDomainRename() API and domain "foo" will be renamed to "bar". We currently support only renaming inactive domains without snapshots. Renaming procedure takes care of domain log, config, guest agent path and should be able to recover in case of failure.

[libvirt] [PATCHv2 0/2] Added waiting for DAD to finish for bridge address.
by Maxim Perevedentsev 05 Aug '15

05 Aug '15

This is a fix for commit db488c79173b240459c7754f38c3c6af9b432970 dnsmasq main process which is relied on when waiting for DAD to complete exits without actually waiting for DAD. This is dnsmasq daemon's task. It seems to be a race that DAD finished before dnsmasq main process exited. The above commit needs the execution to block until DAD finishes for bridge IPv6 address because then it closes dummy tap device. Thus we need to ensure this ourselves. So we periodically poll the kernel using netlink and check whether there are any IPv6 addresses assigned to bridge which have 'tentative' state. After DAD is finished, execution continues. I guess that is what dnsmasq was assumed to do. We use netlink to dump information about existing IPv6 addresses. Netlink's response is a multi-part message. Unfortunately, the current implementation of virNetlink treats such messages as faulty and throws an error. So the patch 2/2 adds multi-part nelink response support. Update v2: fixed syntax.

[libvirt] [PATCH] conf: Resolve Coverity FORWARD_NULL
by John Ferlan 05 Aug '15

05 Aug '15

The recent changes to perform SCSI device address checks during the post parse callbacks ran afoul of the Coverity checker since the changes assumed that the 'xmlopt' parameter to virDomainDeviceDefPostParse would be non NULL (commit id 'ca2cf74e87'); however, what was missed is there was an "if (xmlopt &&" check being made, so Coverity believed that it could be possible for a NULL 'xmlopt'. Checking the various calling paths seemingly disproves that. If called from virDomainDeviceDefParse, there were two other possible calls that would end up dereffing, so that path could not be NULL. If called via virDomainDefPostParseDeviceIterator via virDomainDefPostParse there are two callers (virDomainDefParseXML and qemuParseCommandLine) which deref xmlopt either directly or through another call. So I'm removing the check for non-NULL xmlopt.

[libvirt] Libvirt error in Openstack Tempest attaching disk on arm64 system
by Clark Laughlin 04 Aug '15

04 Aug '15

I am running Openstack Tempest on an arm64 platform and am seeing some test failures related to attaching volumes to an instance. This is an example of the disk XML generated by one of the tests: <disk type="block" device="disk"><driver name="qemu" type="raw" cache="none"/<source dev="/dev/disk/by-path/ip-10.7.1.2:3260-iscsi-iqn.2010-10.org.openstack:volume-5a204339-80cb-4d06-aecf-2a8a2c970b0e-lun-1"/><target bus="virtio" dev="vdb"/><serial>5a204339-80cb-4d06-aecf-2a8a2c970b0e</serial></disk> The test is failing with the error "XML error: No PCI buses available". I am trying to find the relevent source locations for this functionality in either in the nova libvirt driver or in the libvirt source itself. I am not sure why I am getting an error about no PCI buses when the bus specified in the XML is "virtio". I would appreciate any pointers / help. Thank you, Clark L

[libvirt] [PATCH] qemuProcessStart: Be tolerant to relabel errors for session mode
by Michal Privoznik 04 Aug '15

04 Aug '15

https://bugzilla.redhat.com/show_bug.cgi?id=1124841 When the daemon is running under unprivileged user, that is under qemu:///session, there are plenty of operations we can't do. What we can do is to go with best effort. One of such cases is relabeling domain resources (be it disks, sockets, regular files, etc.) during domain startup process. While we may successfully set DAC labels, we can be fairly certain that any attempt to change SELinux labels will fail. Therefore we should tolerate relabelling errors and just let qemu to try access the resources. If it fails, our error reporting system is strong enough to articulate the exact error to the user anyway.

In gnutls 3.4.3 there is a regression in the loading of private keys via gnutls_x509_privkey_import. We already have a workaround to deal with failures on older gnutls, but the error code that the new gnutls returns is different. Extend the workaround so that is checks for GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE too. See also gnutls https://bugzilla.redhat.com/show_bug.cgi?id=1250020 Signed-off-by: Daniel P.

[libvirt] [PATCH v2 0/3] Disable floppy disk for PowerPC VMs
by Kothapally Madhu Pavan 04 Aug '15

04 Aug '15

This is an attempt to fix: Libvirt BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1180486 Libvirt currently assumes ISA_based floppy disks to be available across all architectures and machine types. However, PowerPC Book 3S compatible ('ie pseries) virtual machines do not support Floppy disks. This patch series prevents libvirt from launching ppc64[le] -based 'pseries' VMs with floppy devices. This version of patch attempts to fulfill the coments of Andrea Bolognani and Jan Tomko on previous version of patch. --- Kothapally Madhu Pavan (3): Caps: Disable floppy disk for PowerPC VM Avoid starting a PowerPC VM with floppy disk test: Introduce test case to disallow floppy disk on pseries src/qemu/qemu_capabilities.c | 15 +++++-- src/qemu/qemu_command.c | 8 ++++ .../qemuxml2argv-disk-floppy-pseries.args | 6 +++ .../qemuxml2argv-disk-floppy-pseries.xml | 41 ++++++++++++++++++++ tests/qemuxml2argvtest.c | 1 5 files changed, 67 insertions(+), 4 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-floppy-pseries.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-floppy-pseries.xml -- Kothapally Madhu Pavan

[libvirt] [PATCH 00/13] Move generic virsh data to a separate module vsh
by Erik Skultety 04 Aug '15

04 Aug '15

The idea behind this is that in order to introduce virt-admin client (and later some commands/APIs), there are lots of methods in virsh that can be easily reused by other potential clients like command and command argument passing or error reporting. !!! IMPORTANT !!! These patches cannot be compiled separately, the series is split more or less logically into chunks only to be more readable by the reviewer. I started this at least 4 times from scratch and still haven't found a way that splitting virsh could be done with several independent applicable commits, rather than having one massive commit in the end. Erik Skultety (13): tools: Introduce new client generic module vsh vsh: Remove client specific data, only generic data are kept tools: apply s/vshX/virshX to all virsh specific data virsh: remove generic data, only client specific are kept virsh: Rename client specific methods in virsh.h vsh: vshControl now includes client private data and client specific progname vsh: Make use of introduced private data vsh: Introduce client hooks vsh: Make use of newly introduced client side hooks vsh: Introduce new global initializer vsh: Make separated generic methods public virsh: Introduce connection handler tools: Update makefile to include 'vsh' sources as well cfg.mk | 2 +- po/POTFILES.in | 3 +- tools/Makefile.am | 4 + tools/virsh-console.c | 13 +- tools/virsh-console.h | 8 +- tools/virsh-domain-monitor.c | 201 ++-- tools/virsh-domain-monitor.h | 4 +- tools/virsh-domain.c | 532 +++++---- tools/virsh-domain.h | 14 +- tools/virsh-edit.c | 8 +- tools/virsh-host.c | 131 ++- tools/virsh-interface.c | 80 +- tools/virsh-interface.h | 12 +- tools/virsh-network.c | 72 +- tools/virsh-network.h | 10 +- tools/virsh-nodedev.c | 37 +- tools/virsh-nwfilter.c | 33 +- tools/virsh-nwfilter.h | 10 +- tools/virsh-pool.c | 104 +- tools/virsh-pool.h | 10 +- tools/virsh-secret.c | 27 +- tools/virsh-snapshot.c | 75 +- tools/virsh-volume.c | 103 +- tools/virsh-volume.h | 14 +- tools/virsh.c | 2673 ++++-------------------------------------- tools/virsh.h | 481 +------- tools/vsh.c | 2332 ++++++++++++++++++++++++++++++++++++ tools/vsh.h | 489 ++++++++ 28 files changed, 3906 insertions(+), 3576 deletions(-) create mode 100644 tools/vsh.c create mode 100644 tools/vsh.h -- 1.9.3

[libvirt] libvirt 1.2.17 fails
by Jason Helfman 04 Aug '15

04 Aug '15

Hello All, I am getting build failures on the latest build, and it is currently blocking my commit of the update. Looks like xhtml, is a new build requirement. I added it to the list of dependencies, however it is failing to build within our build cluster. http://meatwad.mouf.net/rubick/poudriere/data/93i386-jgh/2015-07-27_15h41m2… (also attached for historical purposes) I am able to get this to build locally, but trying to distinguish what is different compared with a clean system. Here is the listing of files contained in the xhtml package: xhtml-1.0.20020801_4: /usr/local/share/xml/dtd/xhtml/catalog.xml /usr/local/share/xml/dtd/xhtml/xhtml-dcl.soc /usr/local/share/xml/dtd/xhtml/xhtml-lat1.ent /usr/local/share/xml/dtd/xhtml/xhtml-special.ent /usr/local/share/xml/dtd/xhtml/xhtml-symbol.ent /usr/local/share/xml/dtd/xhtml/xhtml.soc /usr/local/share/xml/dtd/xhtml/xhtml1-frameset.dtd /usr/local/share/xml/dtd/xhtml/xhtml1-strict.dtd /usr/local/share/xml/dtd/xhtml/xhtml1-transitional.dtd /usr/local/share/xml/dtd/xhtml/xhtml1.dcl Thanks in advance!

[libvirt] [PATCH v11 0/5] nodeinfo: Add support for subcores
by Andrea Bolognani 03 Aug '15

Only patch 1/5 has been updated, all the other patches are the same as v8: 2/5 https://www.redhat.com/archives/libvir-list/2015-July/msg01045.html 3/5 https://www.redhat.com/archives/libvir-list/2015-July/msg01048.html 4/5 https://www.redhat.com/archives/libvir-list/2015-July/msg01049.html 5/5 https://www.redhat.com/archives/libvir-list/2015-July/msg01050.html I'm including the full history below. Cheers. Changes in v11: * don't declare variables only used inside a code block guarded by #ifdef outside of said code block * use virBitmapNextSetBit() instead of going through all possible index values and calling virBitmapIsBitSet() for each one Changes in v10: * don't attempt to close a file that wasn't opened * report a detailed error to help with diagnosis Changes in v9: * take into account the fact that kvm might not be loaded or even installed Changes in v8: * shortened test names so that make dist doesn't stop working again Changes in v7: * rebased on top of master now that the series this one builds on have been merged Changes in v6: * updated to work on top of [PATCH v2 00/10] nodeinfo: Various cleanups Changes in v5: * streamlined the logic used to decide whether the subcore configuration is valid and moved it to a separate function * split the tests into separate commits for easier review and to hopefully avoid having trouble with the list due to the message size Changes in v4: * removed a printf() statement * fixed typo in a commit message Changes in v3: * the function to get the number of threads per subcore has been moved to the from virarch.c, which deals with architecture names only and is therefore not the right place to read host configuration, to nodeinfo.c where the rest of this stuff lives * said function has also been given a shorter name * the "valid subcore mode" boolean has been removed: threads_per_subcore will be a positive number if subcores should be taken into account, and if that's not the case (x86 host, tainted configuration) it will simply be zero, so now the code needs to keep track of a single variable instead of two * the test case has been renamed to be more descriptive * the test data has been cleaned up by removing all cpu/cpu*/node* links, which prevented 'make dist' from working due to recursive linking Andrea Bolognani (3): tests: Add subcores1 nodeinfo test tests: Add subcores2 nodeinfo test tests: Add subcores3 nodeinfo test Shivaprasad G Bhat (2): nodeinfo: Fix output on PPC64 KVM hosts tests: Prepare for subcore tests src/libvirt_private.syms | 1 + src/nodeinfo.c | 153 ++++++++++++++++++++- src/nodeinfo.h | 1 + tests/Makefile.am | 6 + [...] tests/nodeinfomock.c | 35 +++++ tests/nodeinfotest.c | 8 +- 1348 files changed, 2134 insertions(+), 6 deletions(-) [...] create mode 100644 tests/nodeinfomock.c -- 2.4.3

[libvirt] [PATCH] qemu: Remove double unlock for domains
by Martin Kletzander 03 Aug '15

03 Aug '15

The virDomainObjListRemove() function unlocks a domain that it's given due to legacy code. And because of that code, which should be refactored, that last virObjectUnlock() cannot be just removed. So instead, lock it right back for qemu for now. All calls to qemuDomainRemoveInactive() are followed by code that unlocks the domain again, plus the domain should be locked during qemuDomainObjEndJob(), so the right place to lock it is right after virDomainObjListRemove(). The only place where this would cause a problem is the autodestroy callback, so we need to get another reference there and uref+unlock it afterwards. Luckily, returning NULL from that function doesn't mean an error, and only means that it doesn't need to be unlocked anymore.

[libvirt] ambiguous ret of qemuDomainDetachVirtioDiskDevice
by zhang bo 03 Aug '15

03 Aug '15

static int qemuDomainDetachVirtioDiskDevice(virQEMUDriverPtr driver, virDomainObjPtr vm, virDomainDiskDefPtr detach) { ....... rc = qemuDomainWaitForDeviceRemoval(vm); if (rc == 0 || rc == 1) ret = qemuDomainRemoveDiskDevice(driver, vm, detach); else ret = 0; /*the return value of 2 is dismissed here, which refers to ETIMEOUT.*/ ........ } ------------------------------------ If it timeouts when qemu tries to del the device, the return value would be modified from 2 to 0 in function qemuDomainDetachVirtioDiskDevice(), which means that, the users would be misleaded that the device has been deleted, however, the device maybe probably failed to be detached after timeout and still in use. That is to say, the function qemuDomainDetachVirtioDiskDevice()'s return value is ambiguous when it's 0, maybe successful, or timeout. Will it be better to pass ETIMEOUT to user? or any other advises? for example, let users themselves dumpxml the guest to check whether the device has been actually detached or not? -- Oscar oscar.zhangbo(a)huawei.com

[libvirt] [PATCH v2] rpc: Remove keepalive_required option
by Martin Kletzander 03 Aug '15

03 Aug '15

Since its introduction in 2011 (particularly in commit f4324e329275), the option doesn't work. It just effectively disables all incoming connections. That's because the client private data that contain the 'keepalive_supported' boolean, are initialized to zeroes so the bool is false and the only other place where the bool is used is when checking whether the client supports keepalive. Thus, according to the server, no client supports keepalive. Removing this instead of fixing it is better because a) apparently nobody ever tried it since 2011 (4 years without one month) and b) we cannot know whether the client supports keepalive until we get a ping or pong keepalive packet. And that won't happen untile after we dispatched the ConnectOpen call. Another two reasons would be c) the keepalive_required was tracked on the server level, but keepalive_supported was in private data of the client as well as the check that was made in the remote layer, thus making all other instances of virNetServer miss this feature unless they all implemented it for themselves and d) we can always add it back in case there is a request and a use-case for it.

[libvirt] [PATCH] lxc: Add option to inherit namespace from a name container or a pid or a netns
by ik.nitk 03 Aug '15

03 Aug '15

lxc / docker containers gives option to inherit the namespaces. Example lxc-start has option [ --share-[net|ipc|uts] name|pid ] where --share-net name|pid means Inherit a network namespace from a name container or a pid. This patch tries to add the similar option to libvirt lxc.

[libvirt] [PATCH 0/4] manage the shmem device source
by Luyao Huang 03 Aug '15

03 Aug '15

Since there is a shmobj leak when let qemu create shmobj by themselves, also the label of shmobj/shmem-server socket is not right. Guest cannot direct use the shmem-server if users enabled selinux. So it will be better to manage it in libvirt. The way i chosed is region the shmem deivce in a list, and save it status to a local file to avoid losing it after restart libvirtd, and count the guest which use it, and let the callers know if there is no guest is using it (then we can relabel/cleanup some resource). Notice: you still cannot use the ivshmem-server if the process label is not correct, just set the socket label is not enought, selinux still will forbid qemu use it, because the shmem-server's process is not correct, you will find the AVC like this (i set up the ivshmem server via shell): type=AVC msg=audit(1437642157.227:73784): avc: denied { connectto } for \ pid=6137 comm="qemu-kvm" path="/tmp/ivshmem_socket" \ scontext=system_u:system_r:svirt_t:s0:c703,c707 \ tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=unix_stream_socket But the problem is we cannot change the running shm-server process label, We need wait ivshmem-server to be a part of qemu progrem, then setup the ivshmem-server by libvirt. we cannot do nothing for the ivshmem-server right now.

Hi All I am currently getting up to speed with the libvirt api, but have noticed there are some big gaps in the Application Development Guide available on the libvirt website. Is there a more recent version of this document available? Kind regards Kevin Walker +968 97651742

Use I/O vector (iovec) instead of one huge memory buffer as suggested in https://bugzilla.redhat.com/show_bug.cgi?id=1026137#c7.
