[libvirt] [PATCH v2] test: fix nwfilter tests following changes in virfirewall.c
by Stefan Berger
Some of the nwfilter tests are now failing since --concurrent shows
up in the ebtables command. To avoid this, implement a function
preventing the probing for lock support in the eb/iptables tools
and use it in the tests.

[libvirt] [PATCH v3] network: Bring netdevs online later
by Matthew Rosato
Currently, MAC registration occurs during device creation, which is
early enough that, during live migration, you end up with duplicate
MAC addresses on still-running source and target devices, even though
the target device isn't actually being used yet.
This patch proposes to defer MAC registration until right before
the guest can actually use the device -- In other words, right
before starting guest CPUs.
Signed-off-by: Matthew Rosato <mjrosato(a)linux.vnet.ibm.com>

Associated BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1081461
Changes for v3:
* Some minor formatting fixes.
* in qemuNetworkIfaceConnect, set VIR_NETDEV_TAP_CREATE_IFUP
unconditionally.
* in qemuDomainAttachNetDevice, call qemuInterfaceStartDevice only for
VIR_DOMAIN_NET_TYPE_DIRECT, _BRIDGE and _NETWORK.
* in qemuProcessStartCPUs, use 'reason' to determine whether or not
qemuInterfaceStartDevices needs to be called. Basically, it needs
to be called for any reason that the system would be initializing
(or re-initializing).

The first 3 patches have been already reviewed by Eric and the first patch has been pushed in the main stream.
Based on the remarks after this 3 reviews, I will produce a V2 for the whole set of patches.
It will be more convenient for me to submit V2 versions patch after patch, only after the previous one has been approved and pushed in the main branch.
The V2 of patch 02/21 has been submitted the 27th of October here:

[libvirt] [PATCH v2 2/21] hyperv: implementation of virConnectGetVersion
I've not received any feedback since, and it has not been pushed in the main stream.
Is there any issue?
I'm still waiting for its approval before submitting the next patch...
Thanks for you answer,
Yves.

[libvirt] [PATCH v4 00/17] LXC IP configuration feature
by Cédric Bosdonnat
Hi all,
Here is an updated version of the lxc IP configuration patch series.
Diffs to v3:
* Took care of Daniel's feedback
* Fixed openvz driver to add support for multiple --ipadd
* Report an error for drivers using IP addresses, but only the first one
in case there are more provided.
* Squashed Patch 11 to have virDomainNetIpsFormat right in the first place
* Fixed regression introduced in qemuConnectDomainXMLToNative: IPs were not
kept over memset for bridge type.
* Reformatted to fit latest make syntax-check changes
Cédric Bosdonnat (17):
Forgot to cleanup ifname_guest* in domain network def parsing
Domain conf: allow more than one IP address for net devices
LXC: set IP addresses to veth devices in the container
lxc conf2xml: convert IP addresses
Allow network capabilities hostdev to configure IP addresses
lxc conf2xml: convert ip addresses for hostdev NICs
Domain network devices can now have a <gateway> element
lxc conf2xml: convert lxc.network.ipv[46].gateway
LXC: use the new net devices gateway definition
LXC: honour network devices link state
virNetDevSetIPv4Address: libnl implementation
Renamed virNetDevSetIPv4Address to virNetDevSetIPAddress
virNetDevAddRoute: implementation using netlink
virNetDevClearIPv4Address: netlink implementation
Renamed virNetDevClearIPv4Address to virNetDevClearIPAddress
Openvz --ipadd can be provided multiple times
Report error if a driver can't handle multiple IP addresses

[libvirt] ANNOUNCE: libguestfs 1.26 released
by Richard W.M. Jones
I'm pleased to announce libguestfs 1.26, a library and set of tools
for accessing and modifying virtual machine disk images. This release
took more than 6 months of work by a considerable number of people,
and has many new features (see release notes below).
You can get libguestfs 1.26 here:
Main website: http://libguestfs.org/
Source: http://libguestfs.org/download/1.26-stable/
You will also need latest supermin from here:
http://libguestfs.org/download/supermin/
Fedora 20/21: http://koji.fedoraproject.org/koji/packageinfo?packageID=8391
It will appear as an update for F20 in about a week.
Debian/experimental coming soon, see:
https://packages.debian.org/experimental/libguestfs0
The Fedora and Debian packages have split dependencies so you can
download just the features you need.
>From http://libguestfs.org/guestfs-release-notes.1.html :
RELEASE NOTES FOR LIBGUESTFS 1.26
New features
Tools
virt-customize(1) is a new tool for customizing virtual machine disk
images. It lets you install packages, edit configuration files, run
scripts, set passwords and so on. virt-builder(1) and virt-sysprep(1)
use virt-customize, and command line options across all these tools are
now identical.
virt-diff(1) is a new tool for showing the differences between the
filesystems of two virtual machines. It is mainly useful when showing
what files have been changed between snapshots.
virt-builder(1) has been greatly enhanced. There are many more ways to
customize the virtual machine. It can pull templates from multiple
repositories. A parallelized internal xzcat implementation speeds up
template decompression. Virt-builder uses an optimizing planner to
choose the fastest way to build the VM. It is now easier to use
virt-builder from other programs. Internationalization support has been
added to metadata. More efficient SELinux relabelling of files. Can
build guests for multiple architectures. Error messages have been
improved. (Pino Toscano)
virt-sparsify(1) has a new --in-place option. This sparsifies an image
in place (without copying it) and is also much faster. (Lots of help
provided by Paolo Bonzini)
virt-sysprep(1) can delete and scrub files under user control. You can
lock user accounts or set random passwords on accounts. Can remove more
log files. Can unsubscribe a guest from Red Hat Subscription Manager.
New flexible way to enable and disable operations. (Wanlong Gao, Pino
Toscano)
virt-win-reg(1) allows you to use URIs to specify remote disk images.
virt-format(1) can now pass the extra space that it recovers back to
the host.
guestfish(1) has additional environment variables to give fine control
over the ><fs> prompt. Guestfish reads its (rarely used) configuration
file in a different order now so that local settings override global
settings. (Pino Toscano)
virt-make-fs(1) was rewritten in C, but is unchanged in terms of
functionality and command line usage.
Language bindings
The OCaml bindings have a new Guestfs.Errno module, used to check the
error number returned by Guestfs.last_errno.
PHP tests now work. (Pino Toscano)
Inspection
Inspection can recognize Debian live images.
Architectures
ARMv7 (32 bit) now supports KVM acceleration.
Aarch64 (ARM 64 bit) is supported, but the appliance part does not work
yet.
PPC64 support has been fixed and enhanced.
Security
Denial of service when inspecting disk images with corrupt btrfs
volumes
It was possible to crash libguestfs (and programs that use libguestfs
as a library) by presenting a disk image containing a corrupt btrfs
volume.
This was caused by a NULL pointer dereference causing a denial of
service, and is not thought to be exploitable any further.
See commit d70ceb4cbea165c960710576efac5a5716055486 for the fix. This
fix is included in libguestfs stable branches ≥ 1.26.0, ≥ 1.24.6 and
≥ 1.22.8, and also in RHEL ≥ 7.0. Earlier versions of libguestfs are
not vulnerable.
Better generation of random root passwords and random seeds
When generating random root passwords and random seeds, two bugs were
fixed which are possibly security related. Firstly we no longer read
excessive bytes from /dev/urandom (most of which were just thrown
away). Secondly we changed the code to avoid modulo bias. These
issues were not thought to be exploitable. (Both changes suggested by
Edwin Török)
API
GUID parameters are now validated when they are passed to API calls,
whereas previously you could have passed any string. (Pino Toscano)
New APIs
guestfs_add_drive_opts: new discard parameter
The new discard parameter allows fine-grained control over
discard/trim support for a particular disk. This allows the host file
to become more sparse (or thin-provisioned) when you delete files or
issue the guestfs_fstrim API call.
guestfs_add_domain: new parameters: cachemode, discard
These parameters are passed through when adding the domain's disks.
guestfs_blkdiscard
Discard all blocks on a guestfs device. Combined with the discard
parameter above, this makes the host file sparse.
guestfs_blkdiscardzeroes
Test if discarded blocks read back as zeroes.
guestfs_compare_*
guestfs_copy_*
For each struct returned through the API, libguestfs now generates
guestfs_compare_* and guestfs_copy_* functions to allow you to
compare and copy structs.
guestfs_copy_attributes
Copy attributes (like permissions, xattrs, ownership) from one file
to another. (Pino Toscano)
guestfs_disk_create
A flexible API for creating empty disk images from scratch. This
avoids the need to call out to external programs like qemu-img(1).
guestfs_get_backend_settings
guestfs_set_backend_settings
Per-backend settings (can also be set via the environment variable
LIBGUESTFS_BACKEND_SETTINGS). The main use for this is forcing TCG
mode in the qemu-based backends, for example:
export LIBGUESTFS_BACKEND=direct
export LIBGUESTFS_BACKEND_SETTINGS=force_tcg
guestfs_part_get_name
Get the label or name of a partition (for GPT disk images).
Build changes
The following extra packages are required to build libguestfs 1.26:
supermin ≥ 5
Supermin version 5 is required to build this version of libguestfs.
flex, bison
Virt-builder now uses a real parser to parse its metadata file, so
these tools are required.
xz
This is now a required build dependency, where previously it was (in
theory) optional.
Internals
PO message extraction rewritten to be more robust. (Pino Toscano)
podwrapper gives an error if the --insert or --verbatim argument
pattern is not found.
Libguestfs now passes the qemu -enable-fips option to enable FIPS, if
qemu supports it.
./configure --without-qemu can be used if you don't want to specify a
default hypervisor.
Copy-on-write [COW] overlays, used for example for read-only drives,
are now created through an internal backend API (.create_cow_overlay).
Libvirt backend uses some funky C macros to generate XML. These are
simpler and safer.
The ChangeLog file format has changed. It is now just the same as git
log, instead of using a custom format.
Appliance start-up has changed:
* The libguestfs appliance now initializes LVM the same way as it is
done on physical machines.
* The libguestfs appliance does not write an empty string to
/proc/sys/kernel/hotplug when starting up.
Note that you must configure your kernel to have
CONFIG_UEVENT_HELPER_PATH="" otherwise you will get strange LVM
errors (this applies as much to any Linux machine, not just
libguestfs). (Peter Rajnoha)
Libguestfs can now be built on arches that have ocamlc(1) but not
ocamlopt(1). (Hilko Bengen, Olaf Hering)
You cannot use ./configure --disable-daemon --enable-appliance. It made
no sense anyway. Now it is expressly forbidden by the configure script.
The packagelist file uses m4 for macro expansion instead of cpp.

[libvirt] [PATCH 0/2] Manage SELinux labels on shared/readonly hostdev's
by John Ferlan
https://bugzilla.redhat.com/show_bug.cgi?id=1082521
Patch 1 is innocuous and perhaps could have been pushed as trivial...
For Patch 2 I wasn't sure if I should use the virSecuritySELinuxSetFilecon
or virSecuritySELinuxSetFileconOptional, so I went with the latter since it
follows what virSecuritySELinuxSetSecurityImageLabelInternal does. Beyond
the check for shared/readonly, the other difference would be for the else
condition which uses the Optional now as opposed to the previous code which
would call virSecuritySELinuxSetSecurityHostdevLabelHelper and use the
non optional call to set the label.
John Ferlan (2):

security: Manage SELinux labels on shared/readonly hostdev's

[libvirt] [PATCH 0/2] Exit from virsh when disconnected due to keepalive
by Martin Kletzander
When the connection in virsh got disconnected due to keepalive, virsh
was trying to reconnect. Adding the REASON_KEEPALIVE to the list of
disconnect reasons after virsh should not reconnect (patch 1/1) was
not enough because our rpc code was rewriting those and that needs to
be fixed too (patch 2/2).

[libvirt] [PATCH] nwfilter: Add support for icmpv6 filtering
by Stefan Berger
Make use of the ebtables functionality to be able to filter certain
parameters of icmpv6 packets. Extend the XML parser for icmpv6 types,
type ranges, codes, and code ranges. Extend the nwfilter documentation,
schema, and test cases.
Being able to filter icmpv6 types and codes helps extending the DHCP
snooper for IPv6 and filtering at least some parameters of IPv6's NDP
(Neighbor Discovery Protocol) packets. However, the filtering will not
be as good as the filtering of ARP packets since we cannot check on IP
addresses in the payload of the NDP packets.

[libvirt] [PATCH v2] automatic create tap device with network type ethernet
by Vasiliy Tolstov
If user not specify script in network type ethernet, assume that user
needs simple tap device created with libvirt.
This patch does not need to run external script to create tap device or
add root to qemu process.
