Subject: [PATCH] tpm: Use /dev/null for cancel path if none was found

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8
|

Content-Transfer-Encoding: 8bit

|

TPM 2 does not implement sysfs files for cancellation of commands.
|
||||
We therefore use /dev/null for the cancel path passed to QEMU.

Subject: [PATCH] security: add MANAGER_MOUNT_NAMESPACE flag
|
||||
|
||||
The VIR_SECURITY_MANAGER_MOUNT_NAMESPACE flag informs the DAC driver
|
||||
if mount namespaces are in use for the VM. Will be used for future
|
||||
changes.
|
||||
|
||||
Wire it up in the qemu driver

Subject: [PATCH] security: dac: relabel spice rendernode
|
||||
|
||||
For a logged in user this a path like /dev/dri/renderD128 will have
|
||||
default ownership root:video which won't work for the qemu:qemu user,
|
||||
so we need to chown it.
|
||||
|
||||
We only do this when mount namespaces are enabled in the qemu driver,
|
||||
so the chown'ing doesn't interfere with other users of the shared
|
||||
render node path

Subject: [PATCH] qemu: ensure TLS clients always verify the server certificate
|
||||
|
||||
The default_tls_x509_verify (and related) parameters in qemu.conf
|
||||
control whether the QEMU TLS servers request & verify certificates
|
||||
from clients. This works as a simple access control system for
|
||||
servers by requiring the CA to issue certs to permitted clients.
|
||||
This use of client certificates is disabled by default, since it
|
||||
requires extra work to issue client certificates.
|
||||
|
||||
Unfortunately the code was using this configuration parameter when
|
||||
setting up both TLS clients and servers in QEMU. The result was that
|
||||
TLS clients for character devices and disk devices had verification
|
||||
turned off, meaning they would ignore errors while validating the
|
||||
server certificate.
|
||||
|
||||
This allows for trivial MITM attacks between client and server,
|
||||
as any certificate returned by the attacker will be accepted by
|
||||
the client.
|
||||
|
||||
This is assigned CVE-2017-1000256 / LSN-2017-0002

Subject: [PATCH] qemu: block: Add function to check if storage source allows
|
||||
concurrent access
|
||||
|
||||
Storage source format backing a shared device (e.g. running a cluster
|
||||
filesystem) needs to support the sharing so that metadata are not
|
||||
corrupted. Add a central function for checking this.

Disk sharing between two VMs may corrupt the images if the format driver

happening.

Pivoting to a unsupported storage type might break the assumption that

shared disks will not corrupt metadata.

Subject: [PATCH] qemu: caps: Add capability for 'share-rw' disk option
|
||||
|
||||
'share-rw' for the disk device configures qemu to allow concurrent
|
||||
access to the backing storage.
|
||||
|
||||
The capability is checked in various supported disk frontend buses since
|
||||
it does not make sense to partially backport it.

Subject: [PATCH] qemu: command: Mark <shared/> disks as such in qemu
|
||||
|
||||
Qemu has now an internal mechanism for locking images to fix specific
|
||||
cases of disk corruption. This requires libvirt to mark the image as
|
||||
shared so that qemu lifts certain restrictions.

Subject: [PATCH] qemu: monitor: Decrease logging verbosity
|
||||
|
||||
The PROBE macro used in qemuMonitorIOProcess and the VIR_DEBUG message
|
||||
in qemuMonitorJSONIOProcess create a lot of logging churn when debug
|
||||
logging is enabled during monitor communication.
|
||||
|
||||
The messages logged from the PROBE macro are rather useless since they
|
||||
are reporting the partial state of receiving the reply from qemu. The
|

Subject: [PATCH] virlog: determine the hostname on startup CVE-2018-6764
|
||||
|
||||
At later point it might not be possible or even safe to use getaddrinfo(). It
|
||||
can in turn result in a load of NSS module.
|
||||
|
||||
Notably, on a LXC container startup we may find ourselves with the guest
|
||||
filesystem already having replaced the host one. Loading a NSS module
|
||||
from the guest tree would allow a malicous guest to escape the
|
||||
confinement of its container environment because libvirt will not yet
|
||||
have locked it down.

Fortunately the extra stuff virGetHostname does is totally irrelevant to

the needs of the logging code, so we can just inline a call to the

native hostname() syscall directly.

Subject: [PATCH] qemuDomainAttachDeviceMknodHelper: Remove symlink before
|
||||
creating it
|
||||
|
||||
https://bugzilla.redhat.com/show_bug.cgi?id=1528502
|
||||
|
||||
So imagine you have /dev/blah symlink which points to /dev/sda.
|
||||
You attach /dev/blah as disk to your domain. Libvirt correctly
|
||||
creates the /dev/blah -> /dev/sda symlink in the qemu namespace.
|
||||
However, then you detach the disk, change the symlink so that it
|
||||
points to /dev/sdb and tries to attach the disk again. This time,
|
||||
however, the attach fails (well, qemu attaches wrong disk)
|
||||
because the code assumes that symlinks don't change. Well they
|
||||
do.
|
||||
|
||||
This is inspired by test fix written by Eduardo Habkost.

Subject: [PATCH] nwfilter: increase pcap buffer size to be compatible with
|
||||
TPACKET_V3
|
||||
|
||||
When an nwfilter rule sets the parameter CTRL_IP_LEARNING to "dhcp",
|
||||
this turns on the "dhcpsnoop" thread, which uses libpcap to monitor
|
||||
traffic on the domain's tap device and extract the IP address from the
|
||||
DHCP response.
|
||||
|
||||
If libpcap on the host is built with HAVE_TPACKET3 defined (to enable
|
||||
support for TPACKET_V3), the dhcpsnoop code's initialization of the
|
||||
libpcap socket would fail with the following error:
|
||||
|
||||
virNWFilterSnoopDHCPOpen:1134 : internal error: pcap_setfilter: can't remove kernel filter: Bad file descriptor
|
||||
|
||||
It turns out that this was because TPACKET_V3 requires a larger buffer
|
||||
size than libvirt was setting (we were setting it to 128k). Changing
|
||||
the buffer size to 256k eliminates the error, and the dhcpsnoop thread
|
||||
once again works properly.
|
||||
|
||||
A fuller explanation of why TPACKET_V3 requires such a large buffer,
|
||||
for future git spelunkers:
|
||||
|
||||
libpcap calls setsockopt(... SOL_PACKET, PACKET_RX_RING...) to setup a
|
||||
ring buffer for receiving packets; two of the attributes sent to this
|
||||
API are called tp_frame_size, and tp_frame_nr. If libpcap was built
|
||||
with HAVE_TPACKET3 defined, tp_trame_size is set to MAXIMUM_SNAPLEN
|
||||
(defined in libpcap sources as 262144) and tp_frame_nr is set to:
|
||||
|
||||
[the buffer size we set, i.e. PCAP_BUFFERSIZE i.e. 262144] / tp_frame_size.
|
||||
|
||||
So if PCAP_BUFFERSIZE < MAXIMUM_SNAPLEN, then tp_frame_nr (the number
|
||||
of frames in the ring buffer) is 0, which is nonsensical. This same
|
||||
value is later used as a multiplier to determine the size for a call
|
||||
to malloc() (which would also fail).
|
||||
|
||||
(NB: if HAVE_TPACKET3 is *not* defined, then tp_frame_size is set to
|
||||
the snaplen set by the user (in our case 576) plus a small amount to
|
||||
account for ethernet headers, so 256k is far more than adequate)
|
||||
|
||||
Since the TPACKET_V3 code in libpcap actually reads multiple packets
|
||||
into each frame, it's not a problem to have only a single frame
|
||||
(especially when we are monitoring such infrequent traffic), so it's
|
||||
okay to set this relatively small buffer size (in comparison to the
|
||||
default, which is 2MB), which is important since every guest using
|
||||
dhcp snooping in a nwfilter rule will hold 2 of these buffers for the
|
||||
entire life of the guest.
|
||||
|
||||
Thanks to Christian Ehrhardt for discovering that buffer size was the
|
||||
problem (this was not at all obvious from the error that was logged!)

Subject: [PATCH 12/19] cpu_x86: Copy CPU signature from ancestor
|
||||
|
||||
When specifying a new CPU model in cpu_map.xml as an extension to an
|
||||
existing model, we forgot to copy the signature (family + model) from
|
||||
the original CPU model.
|
||||
|
||||
We don't use this way of specifying CPU models, but it's still supported
|
||||
and it becomes useful when someone wants to quickly hack up a CPU model
|
||||
for testing or when creating additional variants of existing models to
|
||||
help with fixing some spectral issues.

capabiltiies
|

|

A microcode update can cause the CPUID bits to change; an example
|
||||
from the past was the update that disabled TSX on several Haswell and
|
||||
Broadwell machines.
|
||||
|
||||
In order to track the x86 microcode version in the QEMU capabilities,
|
||||
we have to fetch it and store it in the host CPU. This also makes the
|
||||
version visible in "virsh capabilities", which is a nice side effect.

|
||||
Subject: [PATCH 16/19] qemu: capabilities: force update if the microcode
|
||||
version does not match
|
||||
|
||||
A microcode update can cause the CPUID bits to change; an example
|
||||
from the past was the update that disabled TSX on several Haswell
|
||||
and Broadwell machines.
|
||||
|
||||
Therefore, place microcode version in the virQEMUCaps struct and
|
||||
XML, and rebuild the cache if the versions do not match.

||||

||||

Some AMD processors only support a non-architectural means of
|
||||
enabling Speculative Store Bypass Disable. To allow simplified
|
||||
handling in virtual environments, hypervisors will expose an
|
||||
architectural definition through CPUID bit 0x80000008_EBX[25].
|
||||
This needs to be exposed to guest OS running on AMD x86 hosts to
|
||||
allow them to protect against CVE-2018-3639.
|
||||
|
||||
Note that since this CPUID bit won't be present in the host CPUID
|
||||
results on physical hosts, it will not be enabled automatically
|
||||
in guests configured with "host-model" CPU unless using QEMU
|
||||
version >= 2.9.0. Thus for older versions of QEMU, this feature
|
||||
must be manually enabled using policy=force. Guests using the
|
||||
"host-passthrough" CPU mode do not need special handling.

Subject: [PATCH] domain_conf: add "default" to list of valid spice channels
|
||||
|
||||
qemu's behavior in this case is to change the spice server behavior to
|
||||
require secure connection to any channel not otherwise specified as
|
||||
being in plaintext mode. libvirt doesn't currently allow requesting this
|
||||
(via plaintext-channel=<channel name>).

Subject: [PATCH] qemu: replace deprecated fedora-13 machine type with pc-0.14
|
||||
|
||||
This addresses https://bugzilla.redhat.com/show_bug.cgi?id=754772 .
|
||||
It should only be applied to Fedora builds of libvirt, F15 and
|
||||
later, so there is no upstream equivalent patch.
|
||||
|
||||
Background:
|
||||
|
||||
During the lifetime of Fedora 13, some features were backported into
|
||||
the F13 build of qemu-kvm from upstream. These features were part of
|
||||
the functionality of machine type "pc-0.13" in upstream qemu-kvm, so a
|
||||
special "fedora-13" machine type was created for the F13 qemu-kvm.
|
||||
Since "fedora-13" became the new "canonical machine type", all new
|
||||
domains created with F13 libvirt tools by default contained that
|
||||
machine type in their configuration file.
|
||||
|
||||
In Fedora 14, a patch was made to qemu to treat the fedora-13 machine
|
||||
type as equivalent to "pc-0.13". When Fedora 15 was released, this was
|
||||
inadvertently changed to make it equivalent to "pc-0.14".
|
||||
|
||||
With the release of Fedora 16, qemu-kvm initially removed support for
|
||||
this machine type, which caused failure of many guest configurations
|
||||
to start. qemu-kvm subsequently re-added the patch to support
|
||||
fedora-13 (as equivalent to pc-0.14), but with the promise that they
|
||||
could remove it with the release of Fedora 17. (see
|
||||
https://bugzilla.redhat.com/show_bug.cgi?id=748218 ).
|
||||
|
||||
Solution:
|
||||
|
||||
In order to create a repeat of the recent problems, prior to F17
|
||||
existing guest configurations need to be updated to change fedora-13
|
||||
to pc-0.14 (which has been determined to be equivalent for all
|
||||
practical purposes in both F15 and F16). That's what this patch does:
|
||||
|
||||
1) Each time libvirtd is started, it calls virDomainLoadAllConfigs()
|
||||
which calls virDomainLoadConfig(); this function has been modified to
|
||||
check for os.machine == "fedora-13", and change it to "pc-0.14" then
|
||||
write the updated config back to disk.
|
||||
|
||||
2) Also, any other time a domain definition is parsed, the parsed
|
||||
version in memory is changed to turn "fedora-13" into "pc-0.14". This
|
||||
handles domains that had been saved to disk prior to the upgrade, and
|
||||
are subsequently restarted.
|
||||
|
||||
3) Finally, whenever a domain definition is formatted into a string,
|
||||
any occurrence of fedora-13 is replaced with pc-0.14 *directly in the
|
||||
virDomainDef* (to avoid multiple warning messages for the same object
|
||||
when it's formatted multiple times). This should deal with those cases
|
||||
where a domain was running at the time of upgrade, and is later
|
||||
saved/snapshotted.
|
||||
|
||||
I had considered doing this with some sed commands in the specfile,
|
||||
but that wouldn't do anything to help the xml saved in image files.
|
||||
|
||||
(Also, one of the xml tests was using the machine type "fedora-13",
|
||||
and since that machine type is treated specially by the rest of this
|
||||
patch, it was failing. That has been changed in a separate patch,
|
||||
which must be applied with this patch, and which *is* also upstream).

commit acbd4965c44c4dbc676dfe89aff970052e376073

|
||||
|
||||
Add support for shared sanlock leases
|
||||
|
||||
A sanlock lease can be marked as shared (rather
|
||||
than exclusive) using SANLK_RES_SHARED flag. This
|
||||
adds support for that flag and ensures that in auto
|
||||
disk mode, any shared disks use shared leases. This
|
||||
also makes any read-only disks be completely
|
||||
ignored.
|
||||
|
||||
These changes remove the need for the option
|
||||
|
||||
ignore_readonly_and_shared_disks
|
||||
|
||||
so that is removed
|
||||
