[libvirt] [PATCH 0/4] qemu: Fix CPU model broken by older libvirt
by Jiri Denemark 17 Oct '17

17 Oct '17

When libvirt older than 3.9.0 reconnected to a running domain started by old libvirt it could have messed up the expansion of host-model by adding features QEMU does not support (such as cmt). This series fixes the reconnection code and adds a hack which fixes CPU definitions which were broken by older libvirt. https://bugzilla.redhat.com/show_bug.cgi?id=1495171 Jiri Denemark (4): qemu: Separate CPU updating code from qemuProcessReconnect conf: Introduce virCPUDefFindFeature qemu: Filter CPU features when using host CPU qemu: Fix CPU model broken by older libvirt src/conf/cpu_conf.c | 40 +++++++++++++++-------- src/conf/cpu_conf.h | 4 +++ src/libvirt_private.syms | 1 + src/qemu/qemu_domain.c | 76 ++++++++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_domain.h | 4 +++ src/qemu/qemu_driver.c | 14 ++++++++ src/qemu/qemu_process.c | 83 ++++++++++++++++++++++++++++++++++-------------- 7 files changed, 186 insertions(+), 36 deletions(-) -- 2.14.2

[libvirt] [PATCH] qemu: Check QEMU error on failed migration
by Jiri Denemark 17 Oct '17

17 Oct '17

When migration fails, QEMU may provide a description of the error in the reply to query-migrate QMP command. We can fetch this error and use it instead of the generic "unexpectedly failed" message.

[libvirt] [PATCH v3] qemu: argv: parse qemu commandline memory arguments
by Kothapally Madhu Pavan 16 Oct '17

16 Oct '17

Existing qemuParseCommandLineMem() will parse "-m 4G" format string. This patch allows it to parse "-m size=8126464k,slots=32,maxmem=33554432k" format along with existing format. And adds a testcase to validate the changes.

[libvirt] LSN-2017-0002 - TLS certificate verification disabled for clients
by Daniel P. Berrange 16 Oct '17

16 Oct '17

Libvirt Security Notice: LSN-2017-0002 ====================================== Summary: TLS certificate verification disabled for clients Reported on: 20171005 Published on: 20171016 Fixed on: 20171016 Reported by: Daniel P. Berrange <berrange(a)redhat.com> Patched by: Daniel P. Berrange <berrange(a)redhat.com> See also: CVE-2017-1000256 Description ----------- The default_tls_x509_verify (and related) parameters in qemu.conf control whether the TLS servers in QEMU request & verify certificates from clients. This works as a simple access control system for QEMU 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 libvirt code was using these configuration parameters 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 any errors while validating the server certificate. Impact ------ A MITM attacker can attack any client connection made by QEMU's character devices and disk devices which have TLS enabled. The attacker can send an arbitrary certificate back to the client QEMU and it will ignore all errors that result during validation. Workaround ---------- Enable the 'default_tls_x509_verify' parameter in qemu.conf restart libvirtd. This will trigger libvirt to turn on certificate verification in QEMU clients. Unfortunately this will also turn on use of client certificates in QEMU servers.

[libvirt] [PATCH] qemu: ensure TLS clients always verify the server certificate
by Daniel P. Berrange 16 Oct '17

16 Oct '17

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.
