Subject: [PATCH] qemuProcessRefreshDisks: Don't skip filling of disk
information if tray state didn't change
Content-type: text/plain
Commit 5ef2582646eb98 added emitting of even when refreshign disk state,
where it wanted to avoid sending the event if disk state didn't change.
This was achieved by using 'continue' in the loop filling the
information. Unfortunately this skips extraction of whether the device
has a tray which is propagated into internal structures, which in turn
broke cdrom media change as the code thought there's no tray for the
device.

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.

The CURLOPT_PUT constant causes a deprecation warning when compiling on
Alpine Edge. The docs indicate it is deprecated since 7.2.1
https://curl.se/libcurl/c/CURLOPT_PUT.html
Since 7.87 the deprecation is now exposed at build time via a compiler
warning.
We already use CURLOPT_UPLOAD in the ESX driver, so this brings the CH

Subject: [PATCH] storage: Fix returning of locked objects from
'virStoragePoolObjListSearch'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
CVE-2023-3750
'virStoragePoolObjListSearch' explicitly documents that it's returning
a pointer to a locked and ref'd pool that maches the lookup function.
This was not the case as in commit 0c4b391e2a9 (released in
libvirt-8.3.0) the code was accidentally converted to use 'VIR_LOCK_GUARD'
which auto-unlocked it when leaving the scope, even when the code was
originally "leaking" the lock.
Revert the corresponding conversion and add a comment that this function
is intentionally leaking a locked object.
Fixes: 0c4b391e2a9
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=2221851

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Repeatedly querying an SR-IOV PCI device's capabilities exposes a
memory leak caused by a failure to free the virPCIVirtualFunction
array within the parent struct's g_autoptr cleanup.

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.
