Subject: [PATCH] Fix off-by-one error in udevListInterfacesByStatus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Ever since this function was introduced in 2012 it could've tried
filling in an extra interface name. That was made worse in 2019 when
the caller functions started accepting NULL arrays of size 0.
This is assigned CVE-2024-1441.

Subject: [PATCH] interface: fix udev_device_get_sysattr_value return value
check
Reviewing the code I found that return value of function
udev_device_get_sysattr_value() is dereferenced without a check.
udev_device_get_sysattr_value() may return NULL by number of reasons.
v2: VIR_DEBUG added, replaced STREQ(NULLSTR()) with STREQ_NULLABLE()
v3: More checks added, to skip earlier. More verbose VIR_DEBUG.

Subject: [PATCH] rpc: avoid leak of GSource in use for interrupting main loop
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] rpc: fix race in waking up client event loop
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The first thread to issue a client RPC request will own the event
loop execution, sitting in the virNetClientIOEventLoop function.
It releases the client lock while running:
virNetClientUnlock()
g_main_loop_run()
virNetClientLock()
If a second thread arrives with an RPC request, it will queue it
for the first thread to process. To inform the first thread that
there's a new request it calls g_main_loop_quit() to break it out
of the main loop.
This works if the first thread is in g_main_loop_run() at that
time. There is a small window of opportunity, however, where
the first thread has released the client lock, but not yet got
into g_main_loop_run(). If that happens, the wakeup from the
second thread is lost.
This patch deals with that by changing the way the wakeup is
performed. Instead of directly calling g_main_loop_quit(), the
second thread creates an idle source to run the quit function
from within the first thread. This guarantees that the first
thread will see the wakeup.

daemon: Export SDL audio environment variables
/etc/sysconfig/libvirtd has a few environment variables for configuring
libvirt SDL audio. The libvirtd process doesn't see these, however, because
they are never exported. Let's export the variables after sourcing the
sysconfig script.
There is another problem here that the commented out values in the
sysconfig script are not neccessarily the actual defaults, we are qemus
mercy here. Not sure how to solve that.

qemu: Allow using regular audio backends with VNC
Currently all host audio backends are disabled if a VM is using VNC, in
favor of the QEMU VNC audio extension. Unfortunately no released VNC
client supports this extension, so users have no way of getting audio
to work if using VNC.
Add a new config option in qemu.conf which allows changing libvirt's
behavior, but keep the default intact.
v2: Fix doc typos, change name to vnc_allow_host_audio

Fix CDROM media change for QEMU when using -device syntax
Disk devices in QEMU have two parts, the guest device and the host
backend driver. Historically these two parts have had the same
"unique" name. With the switch to using -device though, they now
have separate names. Thus when changing CDROM media, for guests
using -device syntax, we need to prepend the QEMU_DRIVE_HOST_PREFIX
constant
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add helper function
qemuDeviceDriveHostAlias() for building a host backend alias
* src/qemu/qemu_driver.c: Use qemuDeviceDriveHostAlias() to determine
the host backend alias for performing eject/change commands in the
monitor

Subject: [PATCH] qemu: Fix USB by product with security enabled
We need to call PrepareHostdevs to determine the USB device path before
any security calls. PrepareHostUSBDevices was also incorrectly skipping
all USB devices.

Trivial virsh.pod additions --all for "list" command and similar
This is just a trivial patch to virsh.pod (from git master). It adds the
following pieces to the virsh man page:
+ Shows the --inactive and --all optional parameters for the list
command.
Closes Bugzilla #575512, reported by Renich Bon Ciric
https://bugzilla.redhat.com/show_bug.cgi?id=575512
+ Corrects the existing description of the list command, to now say
that only running domains are listed if no domains are specified.
The man page up until this point has said all domains are listed if
no domains are specified, which is incorrect.
+ Adds the "shut off" state to the list of states for the list
command.
+ Adds a missing =back around line 755, that pod2man was complaining
was missing.

network: bridge: Don't start network if it collides with host routing
Fedora bug https://bugzilla.redhat.com/show_bug.cgi?id=235961
If using the default virtual network, an easy way to lose guest network
connectivity is to install libvirt inside the VM. The autostarted
default network inside the guest collides with host virtual network
routing. This is a long standing issue that has caused users quite a
bit of pain and confusion.
On network startup, parse /proc/net/route and compare the requested
IP+netmask against host routing destinations: if any matches are found,
refuse to start the network.
v2: Drop sscanf, fix a comment typo, comment that function could use
libnl instead of /proc
v3: Consider route netmask. Compare binary data rather than convert to
string.
v4: Return to using sscanf, drop inet functions in favor of virSocket,
parsing safety checks. Don't make parse failures fatal, in case
expected format changes.
v5: Try and continue if we receive unexpected. Delimit parsed lines to
prevent scanning past newline

qemu: Report cmdline output if VM dies early
qemuReadLogOutput early VM death detection is racy and won't always work.
Startup then errors when connecting to the VM monitor. This won't report
the emulator cmdline output which is typically the most useful diagnostic.
Check if the VM has died at the very end of the monitor connection step,
and if so, report the cmdline output.

v2 of Cole's wlan support
* Incorporated Jim's feedback (v1 & v2)
* Moved case of DEVTYPE == "wlan" up as it's definitive that we have a network interface.
* Made comment more detailed about the wired case to explain better
how it differentiates between wired network interfaces and USB
devices.

Subject: [PATCH] conf: Restore setting default bus for input devices
Prior to v9.3.0-rc1~30 we used to set default bus for <input/>
devices, during XML parsing. In the commit this code was moved to
a post parse callback. But somehow the line that sets the bus in
one specific case disappeared. Bring it back.
Resolves: https://gitlab.com/libvirt/libvirt/-/issues/577
Fixes: c4bc4d3b82fbe22e03c986ca896090f481df5c10
