MIME-Version: 1.0
|

Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
We never release the reference on the GSource created for
|
||||
interrupting the main loop, nor do we remove it from the
|
||||
main context if our thread is woken up prior to the wakeup
|
||||
callback firing.
|
||||
|
||||
This can result in a leak of GSource objects, along with an
|
||||
ever growing list of GSources attached to the main context,
|
||||
which will gradually slow down execution of the loop, as
|
||||
several operations are O(N) for the number of attached GSource
|
||||
objects.

|
||||
The root cause is a bad assumption in the virNetClientIOEventLoop
|
||||
method. This method is run by whichever thread currently owns the
|
||||
buck, and is responsible for handling I/O. Inside a for(;;) loop,
|
||||
this method creates a temporary GSource, adds it to the event loop
|
||||
and runs g_main_loop_run(). When I/O is ready, the GSource callback
|
||||
(virNetClientIOEventFD) will fire and call g_main_loop_quit(), and
|
||||
return G_SOURCE_REMOVE which results in the temporary GSource being
|
||||
destroyed. A g_autoptr() will then remove the last reference.
|
||||
|
||||
What was overlooked, is that a second thread can come along and
|
||||
while it can't enter virNetClientIOEventLoop, it will register an
|
||||
idle source that uses virNetClientIOWakeup to interrupt the
|
||||
original thread's 'g_main_loop_run' call. When this happens the
|
||||
virNetClientIOEventFD callback never runs, and so the temporary
|
||||
GSource is not destroyed. The g_autoptr() will remove a reference,
|
||||
but by virtue of still being attached to the event context, there
|
||||
is an extra reference held causing GSource to be leaked. The
|
||||
next time 'g_main_loop_run' is called, the original GSource will
|
||||
trigger its callback, and access data that was allocated on the
|
||||
stack by the previous thread, and likely SEGV.
|
||||
|
||||
To solve this, the thread calling 'g_main_loop_run' must call
|
||||
g_source_destroy, immediately upon return, to guarantee that
|
||||
the temporary GSource is removed.

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>

Content-type: text/plain
|

|

The previous check was all wrong since it calculated the how long would
|

the netlink message be if the netlink header was the payload and then
|
||||
subtracted that from the whole message length, a variable that was not
|
||||
used later in the code. This check can fail if there are no additional
|
||||
payloads, struct rtattr in particular, which we are parsing later,
|
||||
however the RTA_OK macro would've caught that anyway.

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 3/3] virarptable: End parsing earlier in case of NLMSG_DONE
|
||||
Content-type: text/plain
|
||||
|
||||
Check for the last multipart message right as the first thing. The
|
||||
presumption probably was that the last message might still contain a
|
||||
payload we want to parse. However that cannot be true since that would
|
||||
have to be a type RTM_NEWNEIGH. This was not caught because older
|
||||
kernels were note sending NLMSG_DONE and probably relied on the fact
|
||||
that the parsing just stops after all the messages are walked through,
|
||||
which the NLMSG_OK macro successfully did.

||||

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
