[libvirt] [PATCH 2/2] qemu: add new disk type='lun' for bus='virtio'

As a result of CVE-2011-4127 (see: http://seclists.org/oss-sec/2011/q4/536), qemu (and the kernel) now disable all SG_IO commands on disks via qemu by default. To continue providing this capability to those who specifically ask for it (and hopefully understand the risks), a new libvirt disk type has been created. This new disk type is identical to disk type='block', except that: 1) It is only allowed if bus='virtio' and the qemu version is "new enough" to support it ("new enough" == qemu 0.11 or better), otherwise the domain will fail to start and a CONFIG_UNSUPPORTED error will be logged). 2) The option "scsi=on" will be added to the -device arg to allow SG_IO commands (if type!='lun', "scsi=off" will be added to the -device arg so that SG_IO commands are forbidden). Guests which continue to use disk type='block' will no longer be able to use SG_IO commands on the disk; those that have their disk type changed to type='lun' will still be able to use SG_IO commands. --- docs/formatdomain.html.in | 26 ++++++---- docs/schemas/domaincommon.rng | 16 ++++++ src/conf/domain_conf.c | 5 ++- src/conf/domain_conf.h | 1 + src/locking/domain_lock.c | 1 + src/qemu/qemu_command.c | 25 +++++++++ src/qemu/qemu_driver.c | 4 +- tests/qemuhelptest.c | 24 ++++++--- .../qemuxml2argv-boot-complex-bootindex.args | 4 +- .../qemuxml2argv-boot-complex.args | 4 +- .../qemuxml2argvdata/qemuxml2argv-boot-order.args | 2 +- .../qemuxml2argv-disk-ioeventfd.args | 2 +- .../qemuxml2argvdata/qemuxml2argv-disk-order.args | 4 +- .../qemuxml2argv-encrypted-disk.args | 2 +- tests/qemuxml2argvdata/qemuxml2argv-event_idx.args | 2 +- .../qemuxml2argvdata/qemuxml2argv-virtio-lun.args | 11 ++++ tests/qemuxml2argvdata/qemuxml2argv-virtio-lun.xml | 57 ++++++++++++++++++++ tests/qemuxml2argvtest.c | 22 ++++++-- tests/qemuxml2xmltest.c | 1 + 19 files changed, 178 insertions(+), 35 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-virtio-lun.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-virtio-lun.xml diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 9cf0f12..4245708 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -996,7 +996,7 @@ <dt><code>disk</code></dt> <dd>The <code>disk</code> element is the main container for describing disks.
