[libvirt] [PATCH v4 0/7] Add support for LUKS encrypted devices
by John Ferlan 19 Jul '16

19 Jul '16

According to Dan's post commit response: http://www.redhat.com/archives/libvir-list/2016-July/msg00088.html to the v3 series: http://www.redhat.com/archives/libvir-list/2016-June/msg01935.html using a 'passphrase' usage is not desired, rather a 'volume' usage model should be used for LUKS. So patches 1 & 2 make those alterations to already pushed docs and tests Patch 3 then repurposes the 'passphrase' usage to a 'tls' usage type. I posted with this series since it removed the 'passphrase' usage and thus flushed out any errors in subsequent patches. I could hold off and repost it with the TLS changes that will also need to be made... Patches 4-7 were reviewed previously and had been given what I took as provisional ACK's; however, I reposted the changes after the most recent review "just in case". Fortunately (I guess) I didn't push them along with the other changes. In any case, there are once again posted here - the primary difference between what's posted in this series vs. what was posted previously is the change to use a "volume" secret plus a tweak to the qemuxml2argvtest to fix some issues found while making the change. John Ferlan (7): tests: Adjust LUKS tests to use 'volume' secret type docs: Update docs to reflect LUKS secret changes Repurpose the 'passphrase' secret to 'tls' storage: Add support to create a luks volume qemu: Add secinfo for hotplug virtio disk qemu: Alter the qemuDomainGetSecretAESAlias to add new arg qemu: Add luks support for domain disk docs/aclpolkit.html.in | 2 +- docs/formatsecret.html.in | 81 +++++--- docs/formatstorage.html.in | 16 ++ docs/formatstorageencryption.html.in | 29 ++- docs/schemas/secret.rng | 6 +- include/libvirt/libvirt-secret.h | 2 +- src/access/viraccessdriverpolkit.c | 2 +- src/conf/secret_conf.c | 12 +- src/conf/virsecretobj.c | 2 +- src/libvirt_private.syms | 1 + src/qemu/qemu_alias.c | 10 +- src/qemu/qemu_alias.h | 3 +- src/qemu/qemu_command.c | 9 + src/qemu/qemu_domain.c | 40 +++- src/qemu/qemu_hotplug.c | 126 +++++++++++- src/storage/storage_backend.c | 218 +++++++++++++++++++-- src/storage/storage_backend.h | 3 +- src/util/virqemu.c | 23 +++ src/util/virqemu.h | 6 + .../qemuxml2argv-luks-disk-cipher.xml | 45 ----- .../qemuxml2argvdata/qemuxml2argv-luks-disks.args | 36 ++++ tests/qemuxml2argvdata/qemuxml2argv-luks-disks.xml | 2 +- tests/qemuxml2argvtest.c | 24 ++- .../qemuxml2xmlout-luks-disk-cipher.xml | 1 - tests/qemuxml2xmltest.c | 1 - tests/secretxml2xmlin/usage-passphrase.xml | 7 - tests/secretxml2xmlin/usage-tls.xml | 7 + tests/secretxml2xmltest.c | 2 +- tests/storagevolxml2argvtest.c | 3 +- tests/storagevolxml2xmlin/vol-luks-cipher.xml | 2 +- tests/storagevolxml2xmlin/vol-luks.xml | 2 +- tests/storagevolxml2xmlout/vol-luks-cipher.xml | 2 +- tests/storagevolxml2xmlout/vol-luks.xml | 2 +- 33 files changed, 577 insertions(+), 150 deletions(-) delete mode 100644 tests/qemuxml2argvdata/qemuxml2argv-luks-disk-cipher.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-luks-disks.args delete mode 120000 tests/qemuxml2xmloutdata/qemuxml2xmlout-luks-disk-cipher.xml delete mode 100644 tests/secretxml2xmlin/usage-passphrase.xml create mode 100644 tests/secretxml2xmlin/usage-tls.xml -- 2.5.5

[libvirt] [PATCH] Debug: Record the VM PID in per-VM logs.
by Prerna Saxena 19 Jul '16

19 Jul '16

For certain situations such as Out-of-memory scenarios, it is helpful to record the QEMU PID in the per-VM logs, so that correlation with kernel-reported events is easier. While this is already recorded in libvirt daemon logs as a DEBUG message, I believe it merits more attention :-) Hence introducing it in per-VM log.

[libvirt] [PATCH] virt-admin: Output srv-threadpool-info data as unsigned int rather than signed
by Erik Skultety 19 Jul '16

19 Jul '16

Internally, all the data are represented as unsigned int, it is also documented in the header file that users should use our exported constants that also indicate that the data should be unsigned int. However, when polling for the current server threadpool's configuration, virt-admin uses an incorrect formatting parameter '%d' for printf. Instead, virt-admin should use formatting parameter '%u'.

[libvirt] [PATCH 0/7] Error path cleanup for hotplug and one function move/rename
by John Ferlan 19 Jul '16

19 Jul '16

During review of the LUKS series: http://www.redhat.com/archives/libvir-list/2016-July/msg00488.html it was noted that the error paths should use bools rather than goto failxxx type labels. So this series does that for a few of the affect APIs. There's also changes to qemuDomainAttachMemory since it seems it wasn't properly handling 'props' at least w/r/t how qemuDomainAttachRNGDevice would clean things up. Finally - another part of the review noted that the qemu command line comma escaping could be made more available since the storage driver would potentially need it to build the qemuimg command line. So I moved to virqemu and renamed.

[libvirt] Adding ips and routes to type="ethernet" devices
by Ruben Kerkhof 19 Jul '16

19 Jul '16

Hi all, I've been playing with the recently added support for adding ips and routes to a type"ethernet" kind of device. My goal is to get rid of bridging and use host routes (/32) combined with Bird for a pure layer3 setup. Something similar to what https://www.projectcalico.org/ is doing Instead of p2p addresses with peers they use device routes (ip route add 192.168.0.1/32 dev vnet0) combined with static arp entries. I am a bit stuck though. I've created the vm with a tap device: <interface type='ethernet'> <mac address='00:1a:4a:1b:d9:cc'/> <model type='virtio'/> <rom bar="off"/> <source> <ip address='192.168.42.41' family='ipv4' peer='192.168.42.42' prefix='32'/> <route family='ipv4' address='192.168.100.0' prefix='24' gateway='192.168.42.42'/> </source> </interface> After starting, the link stays down and no ips or routes are being created: root@test1: ~# ip link show dev vnet0 15: vnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether fe:1a:4a:1b:d9:cc brd ff:ff:ff:ff:ff:ff root@test1: ~# ip route show default via 10.10.5.1 dev br1010 10.10.5.0/24 dev br1010 proto kernel scope link src 10.10.5.2 I feel like I'm missing a step. Who is responsible for setting the link up, it this libvirtd, qemu, or do I need to write a qemu-ifup script? Any help is greatly appreciated. Kind regards, Ruben Kerkhof

[libvirt] [PATCH] fs: Fix '<' comparison of value produced by logical not '!'

Commit da665fbd introduced the following condition to virLXCProcessEnsureRootFS and openvzReadFSConf: if (!(<some_var> = virDomainFSDefNew()) < 0) which broke the build on fedora with GCC 5.3.1: "logical not is only applied to the left hand side of comparison".

[libvirt] [PATCH] security: compilation error due to wrong parameter for vah_add_path().
by Julio Faracco 19 Jul '16

19 Jul '16

The commit da665fbd introduced virStorageSourcePtr inside the structure _virDomainFSDef. This is causing an error when libvirt is being compiled. make[3]: Entering directory `/media/julio/8d65c59c-6ade-4740-9cdc-38016a4cb8ae /home/julio/Desktop/virt/libvirt/src' CC security/virt_aa_helper-virt-aa-helper.o security/virt-aa-helper.c: In function 'get_files': security/virt-aa-helper.c:1087:13: error: passing argument 2 of 'vah_add_path' from incompatible pointer type [-Werror] if (vah_add_path(&buf, fs->src, "rw", true) != 0) ^ security/virt-aa-helper.c:732:1: note: expected 'const char *' but argument is of type 'virStorageSourcePtr' vah_add_path(virBufferPtr buf, const char *path, const char *perms, bool recursive) ^ cc1: all warnings being treated as errors Adding the attribute "path" from virStorageSourcePtr fixes this issue.

[libvirt] [PATCH 00/10] Remove caching of address sets
by Tomasz Flendrich 19 Jul '16

19 Jul '16

These patches delete the caching of pci, virtioSerial and ccw address sets. I am deleting them, because they can be recalculated from the domain definition, and there's no point in keeping redundant data, especially because handling a persistent cache of addresses required using functions that released addresses. These functions aren't useful anymore, so they are dropped too. Tomasz Flendrich (10): add virDomainVirtioSerialAddrSetCreateFromDomain qemu_hotplug: generate vioserial address list on demand qemu: remove vioserialaddrs caching Add qemuDomainCCWAddrSetCreateFromDomain qemu_hotplug: generate ccw address list on demand qemu: remove ccwaddrs caching add qemuDomainPCIAddrSetCreateFromDomain qemu_hotplug: generate pci address list on demand qemu: remove pciaddrs caching Remove unused functions that release addresses src/conf/domain_addr.c | 123 ++++++++----------------------- src/conf/domain_addr.h | 15 +--- src/libvirt_private.syms | 4 +- src/qemu/qemu_domain.c | 3 - src/qemu/qemu_domain.h | 4 -- src/qemu/qemu_domain_address.c | 160 ++++++++++++++++++----------------------- src/qemu/qemu_domain_address.h | 11 ++- src/qemu/qemu_hotplug.c | 153 ++++++++++++++++++++++----------------- 8 files changed, 200 insertions(+), 273 deletions(-) -- 2.7.4 (Apple Git-66)
