[libvirt] [PATCH] configure: clarify rationale for checking pkcheck
by Daniel P. Berrange 22 Jul '15

22 Jul '15

We don't need pkcheck binary, but we must detect it in order to see if we're preferring polkit-1 over polkit-0 when both are installed. We should also check $with_dbus to see if we have dbus-devel available, as that's required to talk to polkit-1. Signed-off-by: Daniel P.

[libvirt] ANNOUNCE: libguestfs 1.30 released
by Richard W.M. Jones 22 Jul '15

22 Jul '15

I'm pleased to announce libguestfs 1.30, a library and set of tools for accessing and modifying virtual machine disk images. This release took 9 months of work by a considerable number of people, and has many new features (see release notes below). You can get libguestfs 1.30 here: Main website: http://libguestfs.org/ Source: http://libguestfs.org/download/1.30-stable/ You will also need latest supermin from here: http://libguestfs.org/download/supermin/ Fedora 22+: http://koji.fedoraproject.org/koji/packageinfo?packageID=8391 It will appear as an update for F22/F23 in about a week. Debian/experimental coming soon, see: https://packages.debian.org/experimental/libguestfs0 [ From http://libguestfs.org/guestfs-release-notes.1.html ] NAME guestfs-release-notes - libguestfs Release Notes RELEASE NOTES FOR LIBGUESTFS 1.30 These release notes only cover the differences from the previous stable/dev branch split (1.28.0). For detailed changelogs, please see the git repository, or the ChangeLog file distributed in the tarball. New features New tools virt-dib(1) is a secure and safe alternative to the OpenStack "diskimage-builder" tool. It is compatible with diskimage-builder elements. (Pino Toscano) virt-get-kernel(1) extracts the kernel and ramdisk from a disk image. Previously this functionality was part of virt-builder(1), but the new tool is more featureful. (Pino Toscano) New features in existing tools virt-v2v(1) -i ova mode can now read a wider range of OVA files, and also unpacked files (directories). virt-v2v now securely passes options to curl, so passwords, cookies and so on cannot be seen by users with shell access on the same machine. virt-v2v has a new --password-file option to allow you to securely pass in a password, and to avoid an interactive prompt. virt-v2v disables Windows autoreboot, making debugging conversion failures on Windows easier. virt-v2v now comes with an extensive external test suite. See virt-v2v-test-harness(1). virt-v2v allows virtio drivers to come from any location (Roman Kagan), and drivers can be read directly from the virtio ISO. virt-v2v supports conversion of Windows ≥ 8. Note this is experimental, and possibly broken. Use with caution. virt-v2v can now convert UEFI guests. virt-p2v(1) adds a network configuration dialog. virt-p2v now has p2v.pre, p2v.post and p2v.fail triggers, allowing arbitrary scripts for preparing the host for conversion and tidying up post-conversion. virt-p2v now uses the more advanced metacity window manager (instead of matchbox). virt-sysprep(1) will remove /var/spool/mail/username for non-root accounts (Hu Tao). virt-customize(1), virt-builder(1) and virt-sysprep have the following new options: --commands-from-file allow long lists of commands to be read from a file instead of from the command line (Pino Toscano) --copy copy files inside the guest (Maros Zatko) --copy-in copy host files recursively into the guest (Pino Toscano) --move move files inside the guest (Maros Zatko) --ssh-inject inject SSH keys into a guest (Pino Toscano) --sm-attach --sm-credentials --sm-register --sm-remove --sm-unregister register and unregister a guest from subscription-manager (Pino Toscano) --touch touch a file in the guest (Pino Toscano) --truncate --truncate-recursive truncate files (Maros Zatko) Improvements to virt-customize firstboot support. In particular, Windows firstboot should work as well as Linux (Roman Kagan). virt-df(1) can now use PolicyKit, SASL and other authentication methods when getting the list of domains from libvirt. Improvements to guestfish bash completion (Pino Toscano). Bash completion now completes short options as well as long options (Pino Toscano). guestfish(1) now displays a command synopsis if the number of parameters given to a command is wrong (Hu Tao). virt-builder now supports Red Hat Enterprise Linux versions back to RHEL 3. virt-builder supports SUSE guests using zypper (Cédric Bosdonnat). Language bindings The Java bindings now include validated Javadoc, and other improvements (Pino Toscano). Multiple fixes and improvements to the PHP bindings (Pino Toscano). Inspection Inspection can now get icons from RHEL 7 and CentOS 7. /etc/favicon.png is now allowed to be a symbolic link. For RPM-based guests, inspection now returns RPM Epoch fields. Debian packages now have separate Epoch and Version fields (Nikos Skalkotos). OpenBSD detection added, FreeBSD and NetBSD added as separate "distros", and other BSD inspection improvements and bug fixes (Nikos Skalkotos). CoreOS detection added (Nikos Skalkotos). The package manager in Fedora ≥ 22 is dnf. ReactOS guests can be inspected (Maros Zatko). Add support for UEFI guests. Inspection now works when kernel modules are gzip or xz compressed (Pino Toscano). Inspection now recognizes ppc64 and ppc64le guests (Maros Zatko). Inspection lists the installed applications on Archlinux guests (Nikos Skalkotos). Architectures and platforms PPC64 (POWER7) and PPC64LE (POWER8) architectures are now much better supported, and should work out of the box. For aarch64, we use AAVMF (an open source UEFI implementation based on OVMF) if available to run the appliance. For armv7, we now use the -M virt machine type by default. There is better support for compiling on non-Linux platforms (Pino Toscano, Margaret Lewicka). Libguestfs should now work on MIPS 32 bit little endian ("mipsel"). I have not been able to try 64 bit or big endian. Security CVE-2014-8484 CVE-2014-8485 Libguestfs previously ran the strings(1) utility on untrusted files. Strings could parse BFD headers in an unsafe way, leading to possible arbitrary code execution. Libguestfs now runs strings with a flag to ensure it does not try to parse BFD headers. This could have led to exploitation of the libguestfs appliance, but since libguestfs further constrains the appliance through virtualization, SELinux and other techniques, it was unlikely to have caused any privilege escalation on the host. XPath injection in virt-v2v One possible XPath injection vulnerability was fixed in virt-v2v. This might have allowed a malicious guest which was being converted by virt-v2v to construct an arbitrary XPath expression which would have been evaluated on the host (by the libxml2 library linked to the virt-v2v binary). It is not clear what the effects of this might be. For further information, see upstream commit https://github.com/libguestfs/libguestfs/commit/6c6ce85f94c36803fe2db35a98d… Denial of service problems when using qemu-img info When using the American Fuzzy Lop fuzzer (afl-fuzz) on the qemu-img info command, Richard W.M. Jones found that certain files can cause the qemu-img program to use lots of memory and time (for example 6GB of heap and 14 seconds of CPU time on a fast Intel processor), and in some cases to crash. Since libguestfs may run qemu-img info on disk images to find out what they contain, this transitively could cause libguestfs to hang or consume lots of memory. Libguestfs was modified so that it uses resource limits to limit the space and time used by qemu-img info, to avoid this problem. If a malicious user tries to pass one of these disk images to libguestfs, qemu-img will crash and the crash is reported back to libguestfs callers as an error message. API New APIs guestfs_add_libvirt_dom This exposes a previously private API that allows you to pass a virDomainPtr object directly from libvirt to libguestfs. guestfs_blockdev_setra Adjust readahead parameter for devices. See blockdev --setra command. guestfs_btrfs_balance guestfs_btrfs_balance_cancel guestfs_btrfs_balance_pause guestfs_btrfs_balance_resume guestfs_btrfs_balance_status Balance support for Btrfs filesystems (Hu Tao). guestfs_btrfs_filesystem_defragment Filesystem defragmentation support for Btrfs filesystems (Hu Tao). guestfs_btrfs_image Create an image of a Btrfs filesystem (Chen Hanxiao) guestfs_btrfs_qgroup_assign guestfs_btrfs_qgroup_create guestfs_btrfs_qgroup_destroy guestfs_btrfs_qgroup_limit guestfs_btrfs_qgroup_remove guestfs_btrfs_qgroup_show guestfs_btrfs_quota_enable guestfs_btrfs_quota_rescan Quote support for Btrfs filesystems (Hu Tao). guestfs_btrfs_rescue_chunk_recover Scan and recover the chunk tree in Btrfs filesystems (Hu Tao). guestfs_btrfs_rescue_super_recover Restore superblocks in Btrfs filesystems (Hu Tao). guestfs_btrfs_replace Replace a device in a Btrfs filesystem (Cao Jin). guestfs_btrfs_scrub guestfs_btrfs_scrub_cancel guestfs_btrfs_scrub_resume guestfs_btrfs_scrub_status Scrub a Btrfs filesystem (Hu Tao). guestfs_btrfs_subvolume_get_default Get the default subvolume of a Btrfs filesystem (Hu Tao). guestfs_btrfs_subvolume_show List detailed information about the subvolume of a Btrfs filesystem (Hu Tao). guestfs_btrfstune_enable_extended_inode_refs guestfs_btrfstune_enable_skinny_metadata_extent_refs guestfs_btrfstune_seeding Various tuning parameters for Btrfs filesystems (Chen Hanxiao). guestfs_c_pointer Return the C pointer to the underlying guestfs_h *. This allows interworking of libguestfs bindings with bindings from other libraries. For further information see https://bugzilla.redhat.com/1075164 guestfs_copy_in guestfs_copy_out Flexible APIs for recursively copying directories of files between the host and guest filesystem. Previously these were available only as guestfish commands, but now any API users can call them (Pino Toscano). guestfs_part_get_gpt_guid guestfs_part_set_gpt_guid Get and set the GPT per-partition GUID. guestfs_part_get_mbr_part_type Get MBR partition type (Chen Hanxiao). guestfs_set_uuid_random Set the UUID of a filesystem to a randomly generated value; supported filesystems currently are ext2/3/4, XFS, Btrfs, and swap partitions. (Chen Hanxiao). Other API changes guestfs_disk_create can now use VMDK files as backing files. guestfs_btrfs_subvolume_snapshot takes extra optional parameters (all added by Hu Tao): ro for creating a read-only Btrfs snapshot qgroupid for adding the snapshot to a qgroup guestfs_btrfs_subvolume_create can also take the optional qgroupid parameter (Hu Tao). guestfs_set_uuid can set UUID of swap partitions, Btrfs (Hu Tao, Chen Hanxiao). guestfs_copy_device_to_file and guestfs_copy_file_to_file have a new optional append parameter, allowing you to append to the output file instead of truncating it. guestfs_mkfs has a new optional label parameter to set the initial label of the new filesystem (Pino Toscano). guestfs_set_label and guestfs_set_uuid now set ENOTSUP as errno when there is no implemented support for the filesystem of the specified mountable (Chen Hanxiao). Environment variables now let you write LIBGUESTFS_DEBUG=true, LIBGUESTFS_DEBUG=0 and so on. All guestfs_sfdisk* APIs have been deprecated. Because sfdisk(8) was rewritten, incompatibly, upstream, we don't recommend using these APIs in future code. Use the guestfs_part* APIs as replacements. APIs such as guestfs_download do not truncate /dev/stdout or /dev/stderr when writing to them, meaning that if you redirect stdout or stderr to a file, the file is no longer truncated. Build changes The daemon no longer uses its own separate copy of gnulib. Instead it shares a single copy with the library. OCaml .annot files are now created, so IDEs and editors like emacs and vi can browse OCaml types in the source code. Various fixes to allow different host/appliance architecture builds (Pino Toscano). Automake is now used directly to build all the OCaml programs, instead of ad hoc Makefile rules. One side effect of this is to enable warnings in all the C code used by OCaml programs. -fno-strict-overflow is used throughout the build to avoid dubious GCC optimizations. Multiple cleanups to support GCC 5. OCaml OUnit2 is needed to run some OCaml tests. Creating a statically linked libguestfs.a should work again. The src/api-support subdirectory and its scripts are no longer used. Instead we store in the generator/actions.ml when the API was added to libguestfs. Internationalization The translation service has changed from Transifex to Zanata. Many more translations are available now, for both library and tools messages and documentation. Internals In all OCaml tools, there are now common error, warning, info functions, and common way to set and get the --quiet, -x (trace) and -v (verbose) flags, and colour highlighting used consistently. COMPILE_REGEXP macros are used to simplify PCRE constructors and destructors. In the generator, Pointer arguments have finally been implemented. Internal identifiers no longer use double and triple underscores (eg. guestfs___program_name). These identifiers are invalid for C99 and C++ programs, although compilers would accept them. The daemon no longer parses guestfs_* options from /proc/cmdline. Instead it only takes ordinary command line options. The appliance init script turns /proc/cmdline into daemon command line options. The tests can now run the daemon as a "captive process", allowing it to be run directly on the host. The main advantage of this is we can run valgrind directly on the daemon during testing.

[libvirt] [PATCH 0/5] Additional SCSI generated device address checks
by John Ferlan 21 Jul '15

https://bugzilla.redhat.com/show_bug.cgi?id=1210587 These patches will resolve a couple issues with generation of the <address type='drive' .../> for a SCSI <disk> and <hostdev>. The <disk> generation algorithm 'assumes' that when presented with <target dev='sda'.../> that it can use controller=0 and unit=0 since sda would conceivably be the first device; however, a <hostdev> could attempt to assign itself to that address and it doesn't have a target device name, so it bypasses the virDomainDiskDefDstDuplicates checks that would normally 'catch' two <disk>'s attempting to use the same name. Likewise, if a <hostdev> occupies an <address> and we attempt to hotplug a <disk> without providing an address, the address generation could attempt to place the disk on the already existing host device. John Ferlan (5): conf: Enforce SCSI hostdev address type conf: Add 'bus' and 'target' to SCSI address conflict checks conf: Add SCSI hostdev check for disk drive address already in use conf: Refactor virDomainDiskDefParseXML to pass vmdef conf: Check for hostdev conflicts when assign default disk address docs/formatdomain.html.in | 4 +- src/conf/domain_conf.c | 115 ++++++++++++++++++++++++++++++++-------------- src/conf/domain_conf.h | 3 +- src/qemu/qemu_command.c | 4 +- src/vmx/vmx.c | 22 +++++---- src/vmx/vmx.h | 3 +- 6 files changed, 101 insertions(+), 50 deletions(-) -- 2.1.0

[libvirt] [PATCH 00/13] Improve virsh block job handling
by Peter Krempa 21 Jul '15

21 Jul '15

This series refactors the block job command code so that it is handled by separate functions rather than one mega-method. Additionally this series then fixes the routine for waiting for a block job. As it's perhaps obvious from the patches the API design for the block job APIs is rather unfortunate for users. This series contains a few patches that already were submitted and partially reviewed previously. Peter Krempa (13): virsh: blockjob: Extract block job info code into a separate function virsh: cmdBlockJob: Switch to declarative flag interlocking virsh: blockjob: Split out vshBlockJobSetSpeed from blockJobImpl virsh: block job: separate abort from blockJobImpl virsh: Split out block pull implementation from blockJobImpl virsh: Kill blockJobImpl by moving the final impl into cmdBlockCommit virsh: Refactor argument checking in cmdBlockCommit virsh: Refactor argument handling in cmdBlockCopy virsh: Refactor argument handling in cmdBlockPull qemu: Update state of block job to READY only if it actually is ready virsh: Refactor block job waiting in cmdBlockPull virsh: Refactor block job waiting in cmdBlockCommit virsh: Refactor block job waiting in cmdBlockCopy src/qemu/qemu_driver.c | 10 +- src/qemu/qemu_monitor.h | 1 + src/qemu/qemu_monitor_json.c | 7 + tools/virsh-domain.c | 962 ++++++++++++++++++++++++------------------- 4 files changed, 551 insertions(+), 429 deletions(-) -- 2.4.5

[libvirt] [PATCH v2] network: add an option to make dns public
by Cédric Bosdonnat 21 Jul '15

21 Jul '15

In some use cases we don't want the virtual network's DNS to only listen to the vnet interface. Adding a publiclyAccessible attribute to the dns element in the configuration allows the DNS to listen to all interfaces. It simply disables the bind-dynamic option of dnsmasq for the network. --- This patch is v2 for this one: https://www.redhat.com/archives/libvir-list/2015-June/msg00018.html Diff to v1: * Use bind-interface if public DNS is requested * Add more tests * Write out the public value in the format function * Fixed the rng * Renamed the attribute to public: shouldn't mislead users I tested this patch with several configurations of running networks. The only thing I noted though is that the user may need to adapt the system dnsmasq to avoid address:port conflicts... but hey, when one uses such a hacky feature of the libvirt network, he needs to take care of the rest ;) docs/formatnetwork.html.in | 9 +++++++ docs/schemas/network.rng | 5 ++++ src/conf/network_conf.c | 28 ++++++++++++++++++++-- src/conf/network_conf.h | 1 + src/network/bridge_driver.c | 3 ++- .../nat-network-dns-not-public.conf | 15 ++++++++++++ .../nat-network-dns-not-public.xml | 15 ++++++++++++ .../nat-network-dns-public.conf | 15 ++++++++++++ .../networkxml2confdata/nat-network-dns-public.xml | 15 ++++++++++++ tests/networkxml2xmlin/nat-network-dns-public.xml | 9 +++++++ tests/networkxml2xmlout/nat-network-dns-public.xml | 11 +++++++++ tests/networkxml2xmltest.c | 1 + 12 files changed, 124 insertions(+), 3 deletions(-) create mode 100644 tests/networkxml2confdata/nat-network-dns-not-public.conf create mode 100644 tests/networkxml2confdata/nat-network-dns-not-public.xml create mode 100644 tests/networkxml2confdata/nat-network-dns-public.conf create mode 100644 tests/networkxml2confdata/nat-network-dns-public.xml create mode 100644 tests/networkxml2xmlin/nat-network-dns-public.xml create mode 100644 tests/networkxml2xmlout/nat-network-dns-public.xml diff --git a/docs/formatnetwork.html.in b/docs/formatnetwork.html.in index 6abed8f..0141d93 100644 --- a/docs/formatnetwork.html.in +++ b/docs/formatnetwork.html.in @@ -851,6 +851,15 @@ DNS server. + + The dns element + can have an optional <code>public</code> attribute + Since 1.2.17.

[libvirt] [PATCH v6 0/5] nodeinfo: Add support for subcores
by Andrea Bolognani 21 Jul '15

21 Jul '15

Changes from v5 to v6: * updated to work on top of [PATCH v2 00/10] nodeinfo: Various cleanups I'm only sending patch 1/5 to the list, because all the other commits haven't changed since v5 and because this way there's no need to perform moderation due to the message size. For the same reason, I've heavily edited the following summary by cutting out everything that belonged to a test case. Cheers. Andrea Bolognani (3): tests: Add subcores-default nodeinfo test tests: Add subcores-partial nodeinfo test tests: Add subcores-invalid 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 | 144 ++++++++++++++++++++- src/nodeinfo.h | 1 + tests/Makefile.am | 6 + [...] tests/nodeinfomock.c | 35 +++++ tests/nodeinfotest.c | 5 +- 1348 files changed, 2122 insertions(+), 6 deletions(-) [...] create mode 100644 tests/nodeinfomock.c -- 2.4.3
