-Subject: [PATCH] qemu: Allow creating ppc64 guests with graphics and no USB
- mouse
-
-The existing behavior for ppc64 guests is to always add a USB
-keyboard and mouse combo if graphics are present; unfortunately,
-this means any attempt to use a USB tablet will cause both pointing
-devices to show up in the guest, which in turn will result in poor
-user experience.
-
-We can't just stop adding the USB mouse or start adding a USB tablet
-instead, because existing applications and users might rely on the
-current behavior; however, we can avoid adding the USB mouse if a USB
-tablet is already present, thus allowing users and applications to
-create guests that contain a single pointing device.

- qemuAgentGetInterfaces
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Since its introduction in commit 0977b8aa071 (released in v1.2.14)
-qemuAgentGetInterfaces calls qemuAgentCommand with needReply=false,
-which allows qemuAgentCommand to return 0 even when it did not get
-any reply from the agent.
-
-Set needReply to true, since we dereference it right after.
-
-This can be hit if libvirt is waiting for an event from the agent
-(e.g. shutdown) and the agent cannot reply in time (e.g. due to
-the guest being shut down), as reported in:

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The microcode version checks are used to invalidate cached CPU data we
-get from QEMU. To minimize /proc/cpuinfo parsing the microcode version
-was only read when libvirtd started and cached for the daemon's
-lifetime. However, the CPU microcode can change anytime (updating the
-microcode package can automatically upload it to the CPU) and we need to
-stop caching it to avoid using stale CPU model data.

+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

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-My earlier commit be46f61326 was incomplete. It removed caching of
-microcode version in the CPU driver, which means the capabilities XML
-will see the correct microcode version. But it is also cached in the
-QEMU capabilities cache where it is used to detect whether we need to
-reprobe QEMU. By missing the second place, the original commit
-be46f61326 made the situation even worse since libvirt would report
-correct microcode version while still using the old host CPU model
-(visible in domain capabilities XML).

+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.
+
+Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1378242

-Subject: [PATCH] Revert "qemu: hotplug: Prepare disk source in
- qemuDomainAttachDeviceDiskLive"
-
-Preparing the storage source prior to assigning the alias will not work
-as the names of the certain objects depend on the alias for the legacy
-hotplug case as we generate the object names for the secrets based on
-the alias.
-
-This reverts commit 192fdaa614e3800255048a8a70c1292ccf18397a.

-Subject: [PATCH] tests: rewrite socket to do something sensible and reliable
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The current socket test is rather crazy in that it sets up a server
-listening for sockets and then runs a client connect call, relying on
-the fact that the kernel will accept this despite the application
-not having called accept() yet. It then closes the client socket and
-calls accept() on the server. On Linux accept() will always see that
-the client has gone and so skip the rest of the code. On FreeBSD,
-however, the accept sometimes succeeds, causing us to then go into
-code that attempts to read and write to the client which will fail
-aborting the test. The accept() never succeeds on FreeBSD guests
-with a single CPU, but as you add more CPUs, accept() becomes more and
-more likely to succeed, giving a 100% failure rate for the test when
-using 8 CPUs.
-
-This completely rewrites the test so that it is avoids this designed in
-race condition. We simply spawn a background thread to act as the
-client, which will read a byte from the server and write it back again.
-The main thread can now properly listen and accept the client in a
-synchronous manner avoiding any races.

+
+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
+actual full reply is still logged in qemuMonitorJSONIOProcessLine once
+the full message is received.

+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.

+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 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.
+
+CVE-2017-5715

+Subject: [PATCH 19/19] cpu: define the 'virt-ssbd' CPUID feature bit
+ (CVE-2018-3639)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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
