Subject: [PATCH] PowerPC : Add support for launching VM in 'compat' mode.
PowerISA allows processors to run VMs in binary compatibility ("compat")
mode supporting an older version of ISA. QEMU has recently added support to
explicitly denote a VM running in compatibility mode through commit 6d9412ea
& 8dfa3a5e85. Now, a "compat" mode VM can be run by invoking this qemu
commandline on a POWER8 host: -cpu host,compat=power7.
This patch allows libvirt to exploit cpu mode 'host-model' to describe this
new mode for PowerKVM guests. For example, when a user wants to request a
power7 vm to run in compatibility mode on a Power8 host, this can be
described in XML as follows :
<cpu mode='host-model'>
<model>power7</model>
</cpu>

Subject: [PATCH] PowerPC:Improve PVR handling to fall back to cpu generation.
IBM Power processors differ uniquely across generations (such as power6,
power7, power8). Each generation signifies a new PowerISA version
that exhibits features unique to that generation.
The higher 16 bits of PVR for IBM Power processors encode the CPU
generation, while the CPU chip (sub)version is encoded in lower 16 bits.
For all practical purposes of launching a VM, we care about the
generation which the vCPU will belong to, and not specifically the chip
version. This patch updates the libvirt PVR check to reflect this
relationship. It allows libvirt to select the right CPU generation
in case the exact match for a a specific CPU is not found.
Hence, there will no longer be a need to add each PowerPC CPU model to
cpu_map.xml; just adding entry for the matching ISA generation will
suffice.
It also contains changes to cpu_map.xml since processor generations
as understood by QEMU compat mode go as "power6", "power7" or "power8"

Subject: [PATCH] polkit: Allow password-less access for 'libvirt' group
Many users, who admin their own machines, want to be able to access
system libvirtd via tools like virt-manager without having to enter
a root password. Just google 'virt-manager without password' and
you'll find many hits. I've read at least 5 blog posts over the years
describing slightly different ways of achieving this goal.
Let's finally add official support for this.
Install a polkit-1 rules file granting password-less auth for any user
in the new 'libvirt' group. Create the group on RPM install
https://bugzilla.redhat.com/show_bug.cgi?id=957300
(cherry picked from commit e94979e901517af9fdde358d7b7c92cc055dd50c)

Subject: [PATCH 2/2] daemon: Avoid resetting errors before they are reported
https://bugzilla.redhat.com/show_bug.cgi?id=690733
Commit f44bfb7 was supposed to make sure no additional libvirt API (esp.
*Free) is called before remoteDispatchConnError() is called on error.
However, the patch missed two instances.

Subject: [PATCH] rpm: fix /var/lib/libvirt permissions
https://bugzilla.redhat.com/show_bug.cgi?id=649511
Regression of forcing 0700 permissions (which breaks guest startup
because the qemu user can't see /var/lib/libvirt/*.monitor) was
introduced in commit 66823690e, as part of libvirt 0.8.2.
* libvirt.spec.in (%files): Drop %{_localstatedir}/lib/libvirt,
since libvirt depends on libvirt-client.
(%files client): Guarantee 755 permissions on
%(_localstatedir}/lib/libvirt, since the qemu user must be able to
do pathname resolution to a subdirectory.

Subject: [PATCH] qemu: don't use %.3d format for bus/addr of USB devices
When using 0-prefixed numbers, QEmu will interpret them as octal numbers
(as C convention says); this means that if you attach a device that has
addr > 10 (decimal) you're going to attach a different device.

Subject: Add missing checks for read only connections
X-Git-Url: http://libvirt.org/git/?p=libvirt.git;a=commitdiff_plain;h=71753cb7f7a16ff800381c0b5ee4e99eea92fed3;hp=13c00dde3171b3a38d23cceb3f9151cb6cac3dad
Add missing checks for read only connections
As pointed on CVE-2011-1146, some API forgot to check the read-only
status of the connection for entry point which modify the state
of the system or may lead to a remote execution using user data.
The entry points concerned are:
- virConnectDomainXMLToNative
- virNodeDeviceDettach
- virNodeDeviceReAttach
- virNodeDeviceReset
- virDomainRevertToSnapshot
- virDomainSnapshotDelete
* src/libvirt.c: fix the above set of entry points to error on read-only
connections
Rebased to 0.8.2, mostly changed the call of the error routines

Subject: [PATCH] remote: protect against integer overflow
https://bugzilla.redhat.com/show_bug.cgi?id=717204
CVE-2011-2511 - integer overflow in VirDomainGetVcpus
Integer overflow and remote code are never a nice mix.
This has existed since commit 56cd414.
* src/libvirt.c (virDomainGetVcpus): Reject overflow up front.
* src/remote/remote_driver.c (remoteDomainGetVcpus): Avoid overflow
on sending rpc.
* daemon/remote.c (remoteDispatchDomainGetVcpus): Avoid overflow on
receiving rpc.
